A single machine employing a centrifugal drier and embodying many of the features of the machine illustrated in Fig. 10 has been in use. This machine is provlded with a centrifugal drier basket in which the clothes are washed within the basket While the basket is in its lowermost position, by means of vacuum cups which are reciprocated vertically by more or less complicated mechanical elements, such as gears, levers, etc. The basket is raised out of the water by a foot pedal and is rotated with sufficient velocity to throw off the water in the clothes by centrifugal force. `The rotating mechanism also consists of a series of gears, clutches and friction drives. To dry the clothes after they have been washed necessitates the removal of the cups, the raising of the basket manually by means f the foot pedal and the throwing in of a clutch. It is the usual practice with a machine of this type to wash several batches of clothes in the same wash water, lay the dried clothes aside and then withdraw the wash water and substitute the rinse water, after which operation the washed clothes are rinsed in separate batches. Time in the operation is lost in waiting on two or three batches of clothes to be washed before the rinsing operation can be started, and time is also consumed in waiting for the tub to drain and the rinse water to be put in, and the machine is, of course, unavailable during the rinsing operation for washing purposes, resulting in a further loss of time. Therefore time could be saved by using two machines, first starting both machines washing and then using one for rinsing after the first batch has been washed. The rinsing operation will thereafter be more or less continuous, and the washing operation will also be continuous, except for a change of wash water as it becomes necessary. The cost of manufacturing two machines of the type illustrated in Fig. 10 would be prohibitive from a commercial standpoint, and therefore one of the principal obects of my invention is to n simplify the construction of a machine employing centrifugal driers so that two machines can be combined and mounted upon the same frame and handled as a unit. This construction also affords an increased amount of ballast for the centrifugal drier and therefore materially reduces the vibration of the machine, which is a very important advantage in view of the excessive vibration set up by the drier where a single macliine is used.
Referring to Figs. 1 and 2 disclosing the preferred form of my invention, the apparatus includes a pair of tubs or receptacles 16 and 17 preferably placed side by side in close roximity and supported upon a frame 18, W ich is held at a convenient altitude by three supporting legs 19, only two of which are Visible in the-figure. Two of the les are disposed on opposite sides of the tu 16, and the third is disposed at the extreme end of the machine adjacent the tub 17. The tubs 16 and 17 are each provided with a centrifugal drier basket 20 and 21 respectively, and a hydraulic pump 22 and 23 respectively. The pumps are mounted upon a base member 24 which also supoprts an electric motor 25 disposed between the pumps and adapted to drive them by means of connections to be hereinafter described. Each pump 22 and 23 is provided with a waste outlet controlled by valves 26 and 27 respectively, and the valves are connected to a common drain pipe 28 or hose by means of a pipe 29. lVith this apparatus water may be pumped from one tub to the other if desired by simply opening one of the valves of one tub and directing the pipe 28 into the other tub. Referring to Fig. 2, wherein a complete machine unit is illustrated, the device includes a receptacle or tub 16 adapted to contain the wash water, which is preferably placed in the machine up to the level A indicated by the broken line, the quantity being sufficient to nearly cover the container or basket 2O when it is in its lowermost position as indicated in Fig. 1 in dotted lines.
One of the principal objects of my invention is to produce a washing machine wherein the operation of washing and manipulating the fabrics and wringing or drying the fabrics is performed by means of water circulated by a simple pump, thereby eliminating the mechanical operating elements such as gears, levers and other moving parts. With this in view, I have provided a simple form of pump 22, which comprises a U-shaped Venturi tube terminating at one end in an intake opening 30 and a discharge outlet 31 and having a reduced portion 32 having a cross sectional area less than that of the intake and the outlet of the tube, forming in effect a Venturi tube, in which is mounted for rotation a screw propeller 33 of suitable design. The propeller is adapted to be rotated at high velocity by means of a shaft 34, which extends through the pump easing and is journaled therein in an extended bearing bushing 35, which is fitted in an inwardly projecting boss 36 formed integrally with the pump casing or tube. The bearing bushing 35 and the boss 36 are provided with lubricating holes 37 so that the shaft is lubricated by watcr circulating along the shaft. Leakage of water is prevented by the packing gland 38, which is adapted to be screwed into the pump casing. The shaft is rotated nessuna)A l by means of the motor through the medium of a cone clutch 36', which is adapted to be held in operative engagement with the cone sleeve 37 by the thrust of the propeller, which tends to pull the shaft awa from the motor. The clutch is disengage from the sleeve by means of the clutch lever4 39 when the said lever is moved to the right. The f lever is provided with a counter Weight 40 for the purpose of returning the lever to vertical position, and the operating sleeve 4,1 is located onthe shaft so that the lever 39 will normally hold the clutch in disengaged position. In order to start the pump, the lever 39 isv gentlyV moved toward the right until,
l tension 43, which lwill hereinafter be referred to as the outer center column. The pump 22 is securely mounted upon the base 24, which Aalso supports the motor 25 and the pump 23, and the said pumps are aligned with the motor upon this base and assembled upon the machine as a single Iunit, to which the remaining parts are adjusted Without disturbing the alignment of the motor and the pumps. The pumps are further supported by means of transverse brackets 44, 1g. 2, which straddle the flanges and which are secured to or may be integral with the frame members 18, Fig. 1, which support the tubs. The flange 45 is secured to a collar 46 carried by the bottom of the tub so as to form a water tight connection between the tub and the pump, and the flange 47 of the intake end of the pump is secured toa collar 48 carried by the bottom of the tub and which surrounds the conical intake opening 42.
The discharge end ofthe pump is pro- Ivided with `an integral socket 49 disposed 43 serves as a central support about which the container or basket 20 is adapted to rotate when thebasket is in either raised or lowered position. y
The basket 20,.Figs. 2 and 7, is circular in shape and of slightly smaller diameter than the tub. The side wall '52 is provided with a plurality of perforations 53, Fig. 7, for the purpose of permitting the escape of water from the sides of the basket when the basket is being rotated during the centrifugal drying operation, and is also 'provided with a plurality of conical projections 54, Figs. 2 and 7, which are preferably struck out of the metal forming the side wall. These lugs are for the purpeseof gently rubbing the fabric during the Washing operation as will hereinafter appear.
The central portion of the basket is hollow and consists of a Hat bottomrwall anda conical upper wall 56 forming a chamber 57 therebetween adapted to.\ receive fluid and will hereinafter be referred to as a fluid distributing chamber. The conical wall 56 and' the annular bottom 58 disposed between that Wall and the side wall, are provided with conical lugs 59 similar to those in the side wall and are for a similar purpose. The annular bottom portion 58 is also provided with perforations 60, Fig. 7, for the purpose of permitting Water to drain from the basket when the basket is raised out of the Water into the position illustrated in Fig. 2.
The basket is provided with a plurality of radially disposed water conduits 61, 62 and 63 communicating with the distributing chamber 57 at their inner'ends, and which eX- tend upwardly along the inside of the vertical walls of the basket, where they terminate in discharge nozzles 64, 65 and 66 respectively. The nozzles which are of ample capacity are directed downwardly toward the center of the basket and at an angle to a radial plane traversing each nozzle, so that the reaction of the water discharged by the nozzles tends tov rotate the basket, While the jets strike and manipulate the fabrics and keep them against the rubbing surface on the bottom of the basket. The nozzles 64, 65 and' 66, see Fig. 2` are located at different elevations in the basket and consequently discharge jets of water into the basket at different elevations.
Thenozzles are `also disposed so that they will discharge the Water at different angles with respect to the axis of the basket.
The conical bottom 56 is also provided with a series of discharge orifices or nozzles 66', which open out of the distributing chamber 57 and which discharge upwardly toward the periphery of the basket and in a direction tangent tothe orbit of revolution of the nozzles. These nozzles are disposed `at different distances from the center 'of the basket and consequently the Water jets delivered therefrom operate on different parts of the fabric above them.
The pump 22 is designed to circulate a comparatively large quantity of water, andY for the purpose of ammachine for domestic use this quantity is in excess of a hundred gallons per minute. The water under considerable pressure is discharged from the nozzles, which have comparatively large discharge orifices, and therefore the volume and velocity of the water is suicient to displace and manipulate the fabrics within the basket with such energy that they are thorough- 1y Washed within a comparatively short period of time. Each piece of fabric is subjected simultaneously with the others, to violent continuous agitation by the Water, and as the basket containing the fabrics is `rotated by the reaction of the water discharged from the nozzles, each piece as it is brought into contact with the Walls of the basket is gently rubbed, thereby aiding in the Washing process.
The center of the basket is provided with a conical valve sleeve 67 which is attached to the bottom 55 and the conical bottom 56, so that it closes the center of the chamber 57. The sleeve is provided at its upper end with an annular channel 68, the purpose of which will hereinafter appear. The basket is adapted to [it over an operating cylinder 69, which is slidably mounted for vertical and i rotary movement on the exterior of the outer upon the cylinder 69'.
The upper end of the cylinder 69 is closed by a cap 70 screwed or otherwise secured to the upper end thereof and which is provided with a downwardly projecting brake sleevek 71 fitting over and sliding upon the inner center column 51,so that the cylinder 69 carrying the basket 20 thereon is free to slide vertically on the outer and inner columns .43 and 51 respectively. The basket is therefore free to rotate about the center column as an axis, the columns serving as a bearing for the basket.
The space 72'betwee'n the outer and inner center columns is in open communicationl with the discharge outlet 31 of the pump 2Q, and therefore the cylinder 69 carrying the basket 2O is responsive to Huid pressure within the ump and the center column 72, and when tie pressure within that column exceeds a determined amount, the basket 20 will be raised to the position shown in Fig. 2 by the cylinder 69.
The conical valve 70 on the cylinder 69 is provided with two annular ports 73 and 74, the latter communicating with the interior of the cylinder 69 through ports 75 in that cylinder which are adapted to be uncovered only when the cylinder is raised to its uppermost position, at which time the ports are eX- posed to the interior of the outer center column 43. The port 73 extends through the walls of the cylinder 69 and is disposed beneath the port 74 so that when the cylinder 69 is in its lowermost position, the port 73 will register with the ports 76, Figs. 2 and 8, opening outof the outer center column 43 adjacent the bottom of the tub 16. It will be seen that the ports 75 are closed by the wall of the outer center column43 when the basket is in its lowermost position, and that water Will flow through the ports 76 into the dis- -tributing chambery 57 at this time, from whence` it is discharged into the basket throughthe nozzles 64, 65, 66 and 66 for the purpose of' manipulating andwashing the clothes or fabrics therein.'A The size of the discharge nozzles is so proportioned with respect to the capacity of the pump or the volume of water delivered thereby, that the pressure within the center column while the ports 7 6 `are open and Water is being discharged from the basket nozzles, is insuiicient to raise the basket. The entire quantity of water discharged by the pump is therefore at this time discharged into the basket, with the result that the fabrics or clothes therein are energetically tumbled and jostled about in the basket by the jets, during which operation the basket is revolving at a moderate velocity, and the fabrics are revolving slowly about the center column in the opposite direction. The clothes are rubbed gently by the lugs or knobs 59 by reason of the relative movement of the fabrics and the basket, and the water jets are discharged against different portions of the fabrics throughout the entire washing operation. Each piece is incessantly jostled and rubbed and separated from neighboring pieces in a turbulent mass of soapy water, and by reason of this energetic action the fabrics are Washed in shorter time than is usually required by washing machines, and by a4 means requiring less energY and mechanical-apparatus than is required for mechanically operated Washing elements' driven through gears, levers, etc.
The discharge of water through the ports 7 6 is controlled by a manually operable cylindrical valve or gate 77 provided with gate openings or ports 78, Figs. 2 and 8. This gate is adapted to close the three p ffts 76 shown in Fig. 8, by a rotation of the valve 77 through approximately 60 degrees, but it will be understood that a greater number of ports may be employed thereby reducing the rotary movement required for closing the ports. This gate or valve 77 is provided with a center hub 7 9 loosely fitting the inner center column 51 and the hub is connected with the gate by integral radial Webs or spokes 80 between which the water in the outer center column 43 may freely pass.
T he gate is rotated by means of an operat ingshaft or rod 81, which is rotatably mounted in the inner center column 51, which column is provided with a horizontal slot 82,
Fig. 8, through which a screw or pin 83 prothe top of the inner ,center column 51 and projects through a thrust bearing collar 84 which is screwed on or otherwise secured to the top of the center column 51, and which is provided on its underside with an Vant1- friction bearing 85 adapted to be engaged by an upwardly projecting' annular an 86 carriedby the cylinder, cap 70. This collar 84 serves `therefore as a thrust bearing limit stop for the basket when the basket is in its uppermost position, as indicated 1n Fig. 2. The collar 84 is also provided witha. packing gland 87 surrounding the operatlng rod 81, adapted to prevent the leakage of water from between' the inner center coly umn 51 and the said operating rod. A handle 88 is mounted on the upperend of the rod and serves as a means whereby the rod may be manually operated. A packing gland 89 surrounds theinner center column 51and is screwed into they upper side of the cylinder ca 70 for preyenting leakage of water from Etween the brake sleeve 71 and the inner center column.v This gland is disposed between the upperface of the cap 70 and the thrust collar 84 so that it is out of engagement with the collar 84 when the basket is in its raised position.
When it is desired to wring or dry the clothes or fabrics after they have been washed, the handle 88 is turned one-sixth of a revolution so as to turn the valve 77 into a position that will close the ports 76 in the outer center column 43, as shown in Fig. 8. A downward projecting lug 90 is provided on the under side of the handle 88 which is adapted to drop into V-shaped grooves cut in the top face of the gland 87 at spaces degrees apart so that the handle will be automatically arrested after it has been turned through 60 degrees of a revolu tion. 1 I
When the valve or gate 77 has been turned So that the ports 76 have been closed, the escape of water from the outer center col umn will be entirely shut ofi', land this will cause the pressure in the center column toy rise sufficiently to yraise the basket filled with fabric out of the wash water into the raised position illustrated in Fig. 2. AThe clothes `or 'fabrics within the basket are dried or .wrung after the basket has been raised by causing the basket to be rotated at high velocity, so as to throw ofi the water by centrifugal force.
e means for rotating the basket or centrifugal drier comprises a pair of tapered reaction' turbinetubes 91, one of which is shown in side elevation in Fig. 2, and both of which are shown in plan view in Fig. 7. These tubes are` in communication at their inner ends with ports 92 in the conical valve sleeve 67 which register with the annular valve port 74 in the conical valve 70 carried by the basket, and the tubes extend, as
l tom of the basket 'outwardly into engagement `76 will be shown, from these ports 92 through the dis tributing chamber 57 and through the botand terminate in nozzles 93 beneath the bottom ofthe basket and at the periphery thereof. The nozzles are disposed on ofpposite sides of the basket and are directe in op osite directions tangent to the periphery o the basket and slightly downward so that the water discharged therefrom will be directed downward land against the side of the tub, into the wash water directly beneath. The reaction of the water discharged b basket at the desired'velocity v Referring to Fig. 2, it` will be' seen that the discharge of water through the turbine tubes will commence immediately after the ports 75 in the cylinder 69have been uncovered by the upward movement of the basket, and that the upward movement of the basket and rotation thereof will be occasioned a11t0'- matically as a result of the turning of the handle 8 8 which closes the valve 77.
When it is desired to stop the rotation of the basket after the clothes or fabrics have been sufficiently dried, the handle 88 is again turned in the same direction that it was turned to raise the basket, and this action will cause a. cam 93, mounted in a slotk94 in the rod 81, to be moved into contact with the arcuate tapered brake shoes 95 disposed in notches 96 cut in the inner-center column, and force-them with the interior surface of the brake sleeve 71, Contactin therewith at a point adjacent the lower end thereof. The friction of the shoes 95 against the brake sleeve 71 gradually reduces the velocity of rotation of the basket which may gradually be broue'ht to rest. The basket is thus held l the turbine. whichat this time is materially reduced for the reason that the additional rotation of the valve 77 bv the rd 81 has partly opened the ports 76, so as to permit of the discharge of water into the wash water beneath the basket and thereby partially relieving the pressure within the cylinder 69. The basket mav be supported at any point intermediate the upper and lower positions by the brake shoes 95.
After the fabrics have been removed from the basket, it may be lowered for another washing operation by simply reversing the handle 88, so that it is again brouaht'to its original position, at which time the ports wide onen and the pressure in the outer center column reduced suiiiciently to permit the basket to descend into the wash water. The reverse movement ofthe rod 81greleases the brake shoes 95, so that the basket is free to respond to the pressure within the center column and descend when basket has attained its lowermost position,
the tubes rotates the Figs. 2 and 9, slidably stationary against the power of` the ports 73 will again register with the ports 76 and the discharge of water through the nozzles 64, 65, 66 and 66 will immediately thereafter be resumed. Fabrics to be washed may then be placed in the basket or they may be placed in the basket before it is lowered into the wash water.
Referring to Fig. Q, it will be seen that the basket may be removed so that the tub may be cleaned by simply sliding it upward over the cylinder 69 and thc handle 88. lVhen it is replaced the valve sleeve 67 will seatupon the conical valve 70. The sleeve and the valve are preferably fitted so that a water tight joint is formed there between when the basket is seated on the cone so that water may not leak upward or downward from between the sleeve and the cone, but in order to permit any water which mightI leak past the cone 70 from entering the basket while the basket is being rotated at high speed` the previously referred to annular channel 68 is provided at the upper end of the sleeve 67 to catch the water thrown ott' by the cylinder at this point. A tube 97 establishes communication between the channel 68 and the distributing' chamber 57, whereby water may be discharged from the channel into the chamber. vater leaking into the chamber through the tube 97, or from the ports in the conical valve 70 will be forced outwardly bv centrifugal force through the radial discharge passages (i3 in the basket, from whence it escapes through a minute vent 98. Fig. 2. provided at the elbow of each tube. lVater cannot therefore accumulate in the passages 63 or be discharged from their respective nozzles during the drying operation.
Referring to Figs. 3 and 4, a modified form of turbine for-rotating the basket at high velocity is shown. .In place of the reaction tubes 91 employed in the basket above described, a series of Pelton buckets 99 are disposed around the periphery of the basket Q0 adjacent its bottom edge, forming an impulse and reaction turbine which is adapted to receive a jet or jets of water discharged from a stationary nozzle or nozzles 100. one of which is shown suitably arranged to discharge a jet of water tangent to the periphery of the basket, so that it first strikes the upp'erhalfof each bucket. The lower half of the buckets are provided with a shroud 101 to prevent the radial escape of fiuid from the buckets. These buckets transmit, in a well known manner, rotary motion to the basket when water is discharged against them. The nozzle 100 communicates with the interior of the center column 43 ',1 through a stationarjv tube 102, which is secured to the exterior of the said center column and which receives water therefrom through a port 103 in the said column. This port is controlled by a valve 77, similar in every respect to the valve 77, illustrated in Fi 2 and 8. lVhen the valve 77 is rotated to close the ports 76 to shut off the circulation of water into the basket 20, the port 103 is uncovered and water is discharged through the tube 102 and nozzle 100. When the basket has ascended to its uppermost position the buckets 99 will register with the nozzle 100 and rotary movement will be imparted thereto immediately thereafter.
Referring to Figs. 5 and 6, another modified turbine is illustrated. In this case the basket is rotated by an impulse and reaction turbine 104 provided with vancs 105 arranged in the basket center' around the outer center column 43, so that they will receive water therefrom through the stator element 106 of the turbine. The stator comprises a series of vanes 107 arranged about the inner center column 51, which are adapted to discharge the water horizontally against the buckets or vanes 105 in the rotor 104. The buckets 105 are designed to reverse the direction of flow of the water and discharges it downward out of the turbine.
The crown 108 of the stator 106 is adapted to serve as a guide and bearing for the cylinder 69, to which the basket 20 and the rotor 104 are attached. Water may pass through ports 109 in the stator crown into the upper part of the cylinder 69 for the purpose of raising the basket and holding it in elevated position during the drying operation.
Referring again to Fig. 2, it will be seen that the basket rotates about a double bearing; the lower portion of the basket is supported adjacent its center of centrifugal force by the upper end of the outer center column 43, and the upper end of the basket is supported by the upper end of the inner center column 51. It will be observed that the onl v oil lubrication required for this machine is at the bearings and thrust bearings 110 of the motor. The propeller shaft and the bearing about which the basket rotates are constantly lubricated b v water circula ted by the pump and which is constantly accessible to all of the said bearings during the operation of the machine.
ln Fig. 16, l have shown a modified form of basket wherein the conical bottom 50 extends downward from the center and terminates at the vertical side wall 52 of the basket adjacentthe edge of the flat bottom plate This construction formsa truss inwhich the conical bottom serves as a tension and compression member preventing vertical displacement of the sides of the basket with respect to the center sleeve 67. The reaction tubes 91 are encased by the bottom members and the discharge nozzles thereof project through the bottom plate. The nozzle conduitsl 02 in this basket communicate with thc distributing chamber 57 at a point adjacent the vertical sides thereof. The fabric supiwi porting bottom 56 of this basket requires no drainage perforations as the Water will flow down the conical bottom and pass out of the basket vthrough the perforations in the side of the basket. In certain respects, this form-of basket is preferable to that shown in Fig. 2, for the reason that it is a more rigid and economical construction, and by reason of the shorter nozzle conduits, the resistance ofthe water through them is correspondingly reduced.
The simplicity of the constructions makes it possible to construct and market a ma chine such as is illustrated in Fig. 1, at practically the same cost as the single tub machines now commercially sold and which are capable of doing only half the Work within a longer period of time.
The operation of the complete machine shown in Fig. 1, is as follows Assumingzg that the clutches are disengaged from the motor and that Wash Water has been placed in each tub or receptacle to the level indicated by the dotted line A, Fig. 2, the Washine operation is started by first placing clothes or fabrics which are to be subsequently boiled in one basket and those which are not to be boiled in the other basket Q1. while the baskets are in their lowerniost position. The motor is then started and the clutches 3T moved to connect the pump propeller shafts with the motor. Water will thereafter be circulated through the nozzles (il. (i5. 66 and 66 in the manner previously described. This operation is continued until the fabrics or clothes are thoroughly washed. When the washing operation has been completed, the handle 88 of one tub 16 is turned by the operator until the ports 76 in the outer center column are closed. The basket Will then be raised by the increased pressure in the center column and the basket rotated in the manner previously described. When the fabrics have been dried sufficiently. the rotation of the basketA is arrested by further turning' of the handle 88, which applies the brakes in the manner previouslyT set forth. The other` basket 21 may then be similarlyl raised and rotated to dry the fabrics in the tub 17. during' Which interval the clothes or fabrics in the first basket 20 may be removed and placed in the basket just emptied. The basket of the first tub 16 is next caused to be lowered into the wash water by a reverse movement of the operating handle, which releases the brakes and opens the ports 76.
The fabrics in the second basket 2l are by this time sufficiently dried so that the. operator may then stop the basket by means of tne handle controlling the operation of that basket. The tub 17 containing this batch of fabrics will thereafter be used as a rinsingl machine. IVithout re1novin.r the fabrics the Wash water in this tub is pumped out of the tub through the waste pipe 28'after the valve 27 has been opened to permit of its escape. After the Water has been pumped from the tub 17, which operation requires but a few seconds, the valve 27 is closed and rinse water is placed in the machine. The basket is then lowered so that the fabrics will be manipulated and rinsed by the jets of clear water discharged into the basket. The rinse water may be changed continuously by discharging' clear water from the hydrant into the tub and at the same time permitting an equal quantity to be forced out of the drain pipe 28. The escape of water is controlled by the valve 27, which at such time is set in slightly opened position. Then the fabrics have been sufficiently rinsed they are dried by raising; the basket and rotating it in the manner previously described. The washing' and rinsing operation is henceforth carried on simultaneously until the entire quantity of fabrics have been washed.
It will be seen that during the entire operation, it is unnecessary for the operator to either rinse the fabrics by hand orv handle water saturated fabrics, as is necessary in the operation of other portable Washing` apparatus. The machine operates quietly and may be readily cleaned and inspected. The machine requires piactically no oil lubrication and is controlled by simple operating:` mechanism. rIhe tubs are supported upon a single. frame having' three supporting leg-s provided with castors` so that the frame is free to oscillate slightly when the baskets are rotated. The oscillation is dampened materially by reason of the water ballast in each t-ub and therefor the oscillation is less than that of a single t'ub machine such as is illustrated in Fig. 10, havingr half the amount of Water. A slight amount of oscillation is beneficial. as it relieves the bearings of the basket and center column from excessive strains. but the oscillations of a single. machine becomes excessive when the fabrics are nnbalanced and therefore the extra balla@ provided by the combination ot' two tubs is of decided benefit.
In Fig. 10, I have illustrated a formzoffj washing' machine now in use. in which there is a centrifugal drier and mechanically operated vacuum cups or plunger-s adapted to be reciprocated vertically into and out of Contact with the fabrics within the drier.
In this type of machine the action of the by causing the fabrics to be turned so that dlfferent arts of the fabrics are exposed to the rub ing surfaces, that the fabrics are Washed more thoroughly and in a considerably shorter time than was possible before these improvements had been applied. The fabric turning action is accomplished by meansof jets of water forced upwardly out of nozzles in the bottom of the drier basket, which strike the underside of the fabrics and turn and separate them. The basket is r0- tated with respect to the fabrics by means of a star wheel or intermittent gear, which is adapted to rotate the basket about one-sixth of a revolution during the interval in which the fabrics are being forced against the bottom of the drier by the plungers.
Briefly this type of machine includes a tub 110 having a rotary drier basket 111 rotatably mounted therein upon a center column 112 which extends upwardly through the bottom of the receptacle. The center column also projects downwardly and terminates in a sleeve 113 upon which is slidably and rotatably mounted a driving clutch wheel 114. This wheel is retained upon the sleeve bv means of acollar 115 which also supports the cone member 116 of the clutch.
The driving clutch is provided with a friction ring 117 adapted to engage a friction disc 118. which is driven by an electric motor, not shown. This clutch is provided with a pinion 119 adapted to mesh with a gear 120 when the clutch is in its lowermost position and is adapt/ed to be disengafred when the drivingr clutch 114 is raised. The gear 120 is provided at the lower end of the hub thereof, with a crank 121 havin" a ball stud 122 adapted to fit into a ball socket 123 of the wobble crank 124. The wobble crank is pivoted for universal motion at its lower end and serves to oscillate the-crank lever 125 vertically. A vertical shaft 126 is pivotally secured at its lower end to the free end of the crank lever 125, and the upper end of the shaft projects above the top of the tub and is supported in a guide 127 which also serves as one ofthe leas of the tub.
The plungers of this type of machine are bell-shaped and usually two plungers 128, only one of which is shown, are secured to a bracket 129 which is nivotally mounted on the plunger arm 130. This arm is detachably secured to the vertically operating shaft 126 b means of a socket fitting over the end of t e shaft and a set screw 131 which is adapted to be operated to grip the shaft, by means of a handle 132. lIn this type of machine the plunger arm is usually detached from the shaft during the drying operation when the basket is raised, so that the plungers will not interfere with the rotation of the basket. I have provided an improved means for mountlng the plunger arm, whereb y the arm is hinged to the shaft, so that the plungers may ,betilted back of the shaft as indicated in broken lines in Fig. 10. This construction consists of an auxiliary shaft 133 pivotally hinged to the shaft 126 by a pin 134. The auxlliary shaft has a tongue and groove connection with the shaft 126, and the joint is such that the auxiliary shaft cannot be moved pastthe vertical osition when moved toward the right. henitis desired to tilt the plunger arm, the screw 131 is loosened and the arm is raised vertically until the socket clears the hinge joint. The auxiliary shaft may then be tilted backward to the position lndicated in broken lines in Fig. 10. When the plunger arm is in this position, the center of gravity thereof will lie on the left side of the shaft 126 and therefore will remain in that position until manually tilted to operative position by the operator. Rotation of the gear 120 causes vertical reciprocatory movement of the plungers, so that they are intermittently raised and lowered into contact with the fabrics.
The basket is adapted to be raised out of the wash water and rotated at a high velocity for the purpose of drying the fabrics in the basket. The basket is raised by a center shaft 135, to which the basket is secured at its upper end, by means of a sleeve 136, which slides over the outside of the center. column 112 and forms a bearing for the basket. The shaft 135 extends below the sleeve 113 and is supported upon a lever 137 actuated by a foot lever 138. When the foot lever is pressed down the shaft 135 is raised, thereby lifting the basket out of the water. The nut 139 on the lower end of the shaft 135 engages the lower end of the hub 140 of the -cone clutch 116 and moves it upward into engagement with the driving clutch 114. The cone clutch is splined to the shaft 135 by means of a key 141, and the shaft is rotated by the cone clutch after the clutch has been moved into engagement with the driving clutch. Further upward movement of the shaft raises the driving clutch so that the pinion 119 is disengaged from the gear 120. The plunger driving mechanism is therefore non-operative when the basket 'is in raised position and is being rotated.
The means for raising the basket and rotating it after it has been raised, and the means for reciprocating the plungers are old in the art, and no claim is made to this part of the apparatus. As has been previously stated, my improvements on this type of machine consist in the means for rotating the basket when it is in washing position, whereby the fabrics are rubbed by the knobs on the bottom thereof, as shown in Fig. 10, and in the means for turning the fabrics over in the basket so that different parts of the fabrics are rubbed by the basket and the plungers.
The means for rotating the basket includes the star wheel or intermittent gear shown in Figs. 10 and 11. The gear consists of a driving Wheel 142 carrying a driving pin 143, which cooperates with a star wheel 144. This form ofwheel is well known in the gearing art and therefore its principles of operation will not be described in detail. It will be seen from Fig. 11 that the pin 143 enters a slot 145 at each revolution of the pin and turns -the star wheel through 60 degrees of a revolution, and the star wheel is locked in stationary position during the time the pin is disengaged from the starwheel according to Well known principles of operation. The driving wheel 142 is integral with the crank 121 and is rotated by the gear 120. The star wheel is rotatably mounted on the hub 140 of the cone clutch 116 and is yieldingly connected with the cone clutch by means of compression springs 146. When the driving pin 143 strikes the slot in the star wheel, the springs are first compressed and the basket which is driven by the star wheel is gradually accelerated. lVhen the star Wheel is locked, the springs gradually stop the basket, so that the springs are in effect shock absorbers which cushion the movements of the basket. The driving pin is so positioned with respect to the ball stud 122 that the movement imparted to the basket is at its maximum velocity when the plungers are in their lowermost position, as indicated in Fig. 10. The effect of this apparatus is to rotate the basket when the plungers are engaging the clothes and when they are withdrawing therefrom. The clothes are given a slight movement by the basket as the plungers are withdrawn, thereby bringing different fabrics under the plungers at each downward operation. The fabries are rubbed by the knobs on the bottom of the basket. The fabrics are turned over in the drier by means of jets of water which are discharged upward against the under side of the fabric through nozzles 147 and 148 provided in the bottom of the basket. The nozzles open out of a series of discharge conduits 149 shown in enlargedscale in a slightly modified form in Figs. 12 and 13. The conduits 149 communicate with a hood 150 integral with the lower end of the sleeve 136, which hood forms the upper part of a water chamber 151, Fig. 10, surrounding the center column 112, and closes the top of the chamber when the basket is in its lowermost position. A Venturi tube 152 communicates at one end with the water chamber 151 and at the other end with the interior of the tub 110 through the intake port 153, which is located beneath the basket.
A screw propeller pump 152 is located in the reduced neck of the Venturi tube and is adapted to be rotated at high velocity by means of a chain of gears ,154, 155, 156, the latter ofl which meshes with a bevel gear 157 continuously during the washing operation.`
It is obvious that the propellers may be driven directly by a motor, as is done in the machine illustrated in Fig. 1, or it may be driven by a friction drive operated directly by the friction dise similar to the driveshown in Fig. 14.
Referring to Figs. 14 and 15, I have shown another modified form of washing machine, which consists principally of a tub and vertically reciprocable plungers for manipulating the clothes. Washing machines have been in use employing this method of washing, and the shaft for operating the plungers in such machines is provided with a more or less complicated ratchet and pawl means for revolving the plungers in steps, so that they descend upon the fabrics at a different spot at each downward stroke. Such machines are usually provided with a smooth'bottom for the reason that no means has been provided to turn the fabrics over, and if rubbing surfaces were provided only the undermost fabric-s would be rubbed. This is undesirable for the reason that all of the rubbing would be done on the same piece at the same spot.
In improving such machines, I provide the tubs with means for discharging jets of water upwardly as in the machines previously described and for the same purpose. Instead of a flat, smooth bottom I provide a conical shaped bottom provided with rubbing knobs similar to those employed in the machines illustrated in Figs. 1 and 10.
Referring to Fig. 14, I have diagrammatically illustrated in section my improved machine, which consists of a tub 158 provided with a conical rubbing bottom 159 disposed above the bottom 160 of the tub. This bottom has an opening 161 surrounding the center column 162 and may be removed for the purpose of cleaning the tub. The Venturi tube 163 containing the propeller pump 164 communicates at the end with an annular conduit 165 at the periphery of the tub beneath the bottom thereof, and at the other end with the interior of the tub through the inlet 166 beneath the conical bottom 159. The Water circulated by the pump 164 is discharged into the annular conduit and through a series of discharge nozzles 167 opening out of the conduit and adapted to discharge jets of wash water upwardly and inwardly toward the center of the tub. The water flows through the opening 161 in the conical bottom 159 and is drawn through the pump inlet 166. The fabrics are manipulated by a pair of plungers 168, which are pivotally con nected to a cross beam 169 by means of the links 170. A reciprocable shaft 171 operates throu h the center column 162 and is connectefI to the cross beam. Any mechanical means may be employed for reciprocating the shaft so as to impart reciprocatory movement to the plungers. As the plungers descend they will move in the path indicated in dotted lines in Fig. 14 and will work the fabrics over the conical bottom toward the discharge nozzle 167. The jets from the nozzles will lift and turn the fabrics and .force them toward the center of the tub. The nozzles 167 are disposed at a slight angle with respect to an axial plane so that the jets will move the fabrics Aand revolve them around the center of the tub. -The plungers are not revolved, but as the fabrics are revolving slowly the plungers will encounter a different piece of fabric at each downward stroke. The pump in this machine is driven by means of a friction wheel 172, which contacts with a drive disc or gear 173, which may be a part of the shaft reciprocating mechanism.
In Fig. 15, I have diagrammatically illustrated a machine similar 1n essential elements to the machine illustrated in Fig. 14. The conical bottom in this machine slopes downward from the wall of the tub 158 toward the center thereof, and the nozzles 167 are disposed near 'the center of the tub and are supplied Withiwater from a central chamber The Venturi tube 163 communicates at one end with the center chamber 165 and the other end communicates with the interior of the tube throu h the inlet port 166. The water flows out o? the nozzles near the center of the tube and down toward the pump inlet through the openings 161 at the periphery of the conical bottom 159.
The plungers work the fabrics toward the center of the tub and the jets turn and work them away from the center and revolve them about the center of the tub.
In this machine I have shown a water motor 174 for reci rocating the plungers vertically and whic is adapted to be operated on fluid delivered from the pump 164 through a conduit 175. The water motor consists of a cylinder 174 in which a piston 176 reciprocates. The piston is mounted on a rod 171, which carries the plunger beam 169 and the plungers 168. The cylinder 174 is provided with fluid from conduits 177 and 178, which communicate with opposite ends of the cylinder and open into al valve chamber 179 containing a slide valve 180. The valve chamber is provided with exhaust conduits 181 and 182 which communicate with the opposite ends of the valve chamber. The valve is of the balanced type and is provided at each end with a piston fitting the valve chamber cylinder. The supply conduit 175 discharges into the valve chamber at a point between the pistons of the valve. The pistons are adapted to alternately open and close communication between the supply conduit 175 and the conduits 177 and 178, and as shown, the valve has just been shifted downward by reason of the engagement of the collar 183 secured to the valve rod 184 with the valve. lVhen the valve is in the position shown in Fig. 15, water passes through the-pump and through the conduit 175, past the valve and through conduit 178 in the lower end of the cylinder. The water on the upper side of the piston is being exhausted through conduit 177, the valve chamber, and conduit 181, to the tub. This movement of the water raises the piston and the plungers and when the collar 185 on the lower end of the valve rod strikes the lower end of the valve, the valve will be moved upward so that the flow of water through the motor is reversed.
The pump propeller 164 in this case is shown directly connected with the shaft of an electric motor 186. The hydraulic motor is sim le and less complicated than the usual machinery necessary to reciprocate the plungers. The power required is less and the time consumed in the washing operation is materially shortened by the use of the improvements herein described.
