4 claims. (ci. ss-zai This invention appertains to cleaning machines and particularly to those in which the articles to be cleaned dol not have to -be moved from one container to' another. during theentire cycle of the cleaning operation.

-It has for its object a simple and compact arrangement in a casing' of the various compartments for washing and extracting and fory the actuating and motion transmitting mecha; -nisms.

It also has for its object a simple and efficient means for cleaning and 4extracting the cleaning uid from the articles being cleaned'without the necessity ofv the operator having to handle said articles during the above operations.

Another object is to provide means for elimil nating or greatly reducing the vibration during vFigure 1 is an enlarged sectional view taken approximately on the plane of line I-I Figure 2.

between the agitator and the clothes container and between theclothes container and the bottom of the compartment for thewashing liquid..

The lnventioncomprises, generally, a washing apparatus includinga casing formed with a compartment for receiving a washing liquid, or a rinsing liquid, ua.V clothes container' or basket 4 mounted in the casing, an agitator extending into the container with the container and agitator being mounted to move about a common upright axis with the agitator suspended from the top wall of the compartment, so as to seek its own axis ot rotation, actuating means connected to the agitator to oscillate it about its axis or to v rotate it about its axis, with suitable means for controlling the operation' of the agitator asto oscillation and rotation, and means operable to hold the container from movement with the agitator or to connect the container to theaglltator to move about an axis.asa unit therewith.` The wasmng nquid may be water-.with of without asuitable soap or solvent, or any othersolvent, as

a dry cleaning iiuid. l

During the washing operation, the, agitator is .oscillated, the clothes container is held from Vmovement therewith, so that the clothes are agitated within the container.\ During the extracting or drying operation, the clothes container or basket is clutched to the agitator to rotate as a unit therewith, the E,rotation being at a comparatively high extracting speed. During the extracting operation, a drain passage leading froml the washing compartment is opened, and the valve for this drain passage is controlled by the mechanism, which operates to` clutch the container to the agitator ory to unclutch it from the agitator and hold the same stationary. This operating means operates to close this valve dur# ing the washing operation, when the'container is unolutched from the agitator, and to open the valve when the container is clutched to the agitator. Preferably, the casing of the apparatus is a unitary structure with a washing compartment having a door or doors in its front through which the clothes are loaded and unloaded into and out-of the basket or container, compartments below the clothes compartment into'one of which thev liquid from the clothes compartment may be drained, and in the other of which the l'notor` and two sets of metio-n transmitting means are located. The easing also includes a rear compartment leading from the lower compartment in which the motor is located, through which a motion transmitting lrneirnber extends, this being connected to the agitator through another motion transmitting member which. er:nl tends into the upper portion of theV washing compartment.` TheV drain compartment in theV lower part of the casing maynhave a suitable drain .valve and also may be provided witlLa pump of any suitable description lor transferring the liquid from the drain compartment baci'. up into the washing compartment, if desired'for re-use. l In said drawings. ly is the casing, and in the lower rear portion of said casing is mounted the motori 2,"f'which is here shown as connected by means of a worm and gear reduction unit 3 tothe shaft 4, Figure 1. 5 At the top of the shaft 4 is mounted a driving part or disk 5 having a crank pin '6 so mounted in a slot in the disk 5 that said crank pin 6 may be fixed at various radialdistances from the center of the disk 5 lby means of the adjustment handle 1 for *purposes presently to be described,

Figure 1. f A connecting rod or link 8 connectsl the pin 6 with a crank pin- 9 on the driving section or pan I0' of a cone clutch, said pan being mounted so as 5 to revolve freely on the lower end of a shaft II, I

Figure 1. l

A driven clutch section, as a cone I2, adapted to engage with the driving clutch section or pan I0 is slidably keyed on the lower end of the shaft Il, Figure 1.

A pulley I3 is rigidly connected to the shiftable clutch section or cone I2 and both pulley and cone lare-freeA to revolve in a operating orshifting member./I,4,Lbutany movementvof. the operatingmember';A or shifter I4 in line with the axis of the shaft III-,will either raise or lower the'cone I2 and the pulleyffl3, Figure 1.

A spring I5-acts to normally keep the clutchsection or cone,.l2 engaged with the section or pan Ill, and in order to disengage them the operator must depress a pedal I6 of a lever I1, thus raising a connecting link I8, the upper end of which is connected to the rear arm of the shifting member I4; therefore, the member I4 is raised and carries the pulley I3 and the cone I2 with it, thus releasing the engagement between the clutch section or cone I2 and the section or pan I'ILFigure 1. Idler pulleys, as IB, are rotatably mounted on a forward projection of the member I4 and move up .and down with said member, thus causing a belt I9, which runs over a pulley 20 on the motor shaft, the pulley' I3 and the idiers lal to tighten when the idler pulleys vI 8* are raised and to loosen when they are lowered. In this manner, the pulley 20 on the end of the motor shaft is caused to drive the pulley I3 when the shifting member I4 is raised and is allowed to revolve freely when the shifting member I4 is lowered, Figure 1.

Figure 1 shows the member I4 raised with the o cone I2 disengaged from the pan or section lIl) V/ and the belt I9 tightened, and thus providing a driving connection between the pulley 20 and the pulley I 3 for purposes later described.

The shaft II is rotatablymounted in bearings 2I and 22 mounted in the rear compartment of the casing I and the upper 4end of the shaft I I terminates in a universal joint 23.' The shaft II extends upward from a lower compartment 44? of the casing through the upright rear compartment 44. ,Y I 'I'he universal joint 23 connects the shaft I I with another shaft24, and onthe upper end of the shaft 24 is mounted a bevel gear 25 which engages with another bevel gear 26.' The latter 5 gear is mounted on a shaft 21said shaft 21 and shaft 24 both terminating in an upper bearing 29 located .at the top of the casing I, 4Figure 1.

The shaft 21 is retained in place in any suitable manner, here shown for the purpose of illus- V tration, by the set screw, which engages in a groove in the shaft 21 and prevents said shaft from dropping out of the bearing 28, Figure 1.

Another universal joint 30 is located on the 'lower end of -the shaft 21 and connects said shaft with a shaft 3|, the upper end of an upright shaft w container.

on the lower end ofwhich an agitator 32 is o mounted, so that any motion ofthe shaft 3l is transmitted directly to said agitator 32, Figure 1. The agitator is thus supported from above or suspended, so as to seek its own axis, when ro- 5 tating, and eliminate vibration..v I

The unit 3, shaft 4, disk 5 connecting rod 8, clutch pan I0 and cone I2 constitute one set of motion transmitting means between the motor and the motion transmitting member of shaft 10 II to transmit an oscillating washing movement to the agitator 32. The belt I9 and pulleys constitute another set for transmitting a high extracting speed to the agitator and clothes container or basket clutched to the agitator.

Rotatably mounted at the bottom of the agitator 32 is an extractor basket and clothescontainer 33, and the bottom of said basket is adapted to engage with a clutch member 34 when the clutch-member 34 is held in a raised position by 20 means of a lever 35, as shown-in Figure l.

When the basket 33 is heldin this position, the member 34 engages with the jaws or projections 36 on the'bottom of the basket, thus maintainingthe basket inthe position, as shown in Figure 1, 25 and preventing any oscillation or rotation about its axis. However, it will be noted that with the basket in this position, the agitator 32 can oscillate freely. 'I

On a stem 31-of the member 34 is mounted a 30 drain valve or plate 38 held in place by the pin 39, and it will be noted that when the member 34 is raised by the lever 35 and the basket 33 is held in the cleaning position, that is, with the agitator 32 free to oscillate, the pin 39 presses the plate 35 33'up against the bottom surface 4I) ofthe container 4I, and thus cleaning liquid is kept in the washing container 4I during the washing operation.

leasing the latch 42, then the valve plate 39 is allowed to drop away from the surface 40 and expose the opening 43, then the cleansing fluid contained in the container 4I can fiow down into the lower container 44, and at the same time,.the basket 33 will be allowed to drop vertically until pins or jaws 45 on the bottom thereof engage with the holes 46y in. a clutch plate rigid with and spaced from the lower side of theagitator32 and 1 also spaced from the lower side or bottom of the 50 container 33, and now the agitator 32 and the basket 33 are locked together and will move about an axis as ay single unit for purposes presently described, Figures 1 and 6.

The member 34 constitutes a clutch operable to 55 raise and lower the container or basket, and when 'raised, to hold the basket from movement about its axis during oscillating of the agitator 32, because of the member 34 being interlocked with the jaws 36 in the bottom of the container 33. 50 'Ihe pins or jaws 45 and the holes 46 -in the clutch plate, rigid with the agitator, constitute av clutch operable to lock the container 33 and agitator 32 together` to rotate as a unit, when the container is dropped to disengage the clutch 55 member 34 from the jaws 36 on the bottom of the These two clutch means are operative alternately by the lever 35. When thehandle end of the lever 35 is depressed, the memlber 34 is elevated and also elevates the con- 70 tainer 33, and the member 34 engages the jaws 35 on the bottom of the container 33. This lifting` movement disengages the jaws or pins'45 'from the holes 46 of the clutch plate depending from Athe agitator 32. Lifting of the handle end of the 75 However, when the lever 35 is released by re. n

lever 35 lowers the clutchmember 34, releases it from the jaws36, permits the container' 33 toA drop, and the'pins or Ajaws 45 to enter the holes 46 of the clutch plate depending from the agithe lever 35 and the pedal lever'II, so that when the lever is depressed to tighten the belt I9 and open the clutch 4consisting of the sections III, I2,

the latch 42 will be released. permitting the drain valve, 38 to open and causing the basket 33 to be clutched to the agitator. The connection is here shown as a link 42m connected to the latch and the lever I1, the link being elastic or having a spring 42b therein.4 In Figure l, the spring has stretched to a point where it is about to tripthe' latch 42 with a snap action. y

Handles, as H, 'are aixed to the doors, as 4'I,

to' permit the operator to place -articles to be.

cleaned in, and remove them from, the basket 33, Figure 1. The compartment 44 has a drain valve 5I operable in any well known manner, and also a valve controlled by-pass 52 leading therefrom into the washing compartment 4I, the by-pass having a motor driven pump 54 therein operable from the shaft of the motor' 2. When the valve 52B in the by-passb'is closed, the pump merely o I4 with it. The lsp'rlng I5 assists this motion, and

the cone I2 is caused to engage with the pan I0 andat the same time the idler pulleys I8 are also lowered and the tension' on the belt I9 is released, thus disconnecting the driving effect of the pulley 20 with the pulley -I3, Figure 1.

'Ihe motor is' now started, and causes the disk 5 Since the basket 33 is held up in the position,

as shown, by the member .34, said basket is now heldstationary, and the agitator 32 is'freeto agitate and thus perform the cleansing action on the articles being cleaned, Figure 1.

After the cleaning cycle has been completed, the operator stops 'the motor 2 and releases the latch 42, thus connecting the basket 33 with the agitator 32 and allowing the cleaning fluid to flow out of the'container 4I into the container 44, as

previously described, Figure 1, or he may depress If the motor is i the pedal I'I through the link 42a. not stopped, the depression of the pedal lever Il will throw out the clutch sections IG and I2, tighten the belt I9, and clutch the basket 33 to the agitator 32 for the extracting operation.

The changing of the cleaning iluid from the container 4I down to the container tends to lower the 'center of 'gravity of the entire unit and ing member.

prepares the machine for the extracting cycle .by further stabilizing it against' any possible extractor vibration, Yand the operator now` de- `presses the pedal I6, until itis locked in place by thelatch 49, Figure 1. l' v 'Ihis movement of the pedal 6 `causes the rear arm of the'lever II to rise, thus raising the link I3 and themember I4, disengaging the cone I2 from the pan 'III-'." The idler pulleys I8 are also raised, thus taking .up any slack in the belt I9 and producing a tension vin the same, and the pulley 20 now has a driving connection through the belt I9 with the pulley I3, Figure l.v

With the motor 2 running, the pulley 20 drives the pulley I3 in a rotary motion, and this motion is transferred through the shafts II and -24 and the gears 25 v'and 26 and the shaft 3l, to the agitator 32, and, since the agitator 32 is locked together with the basket 33, the rotary motion is transmitted finally to the extractor basket 33 and thus the cleaning fiuidleft in the articles being cleaned by the cleaning cycle thrown out through the holes, as 50, in the extractor basket 33, Figure l.

Since the agitator 32 andthe basket 33, during 4the extraction cycle are free tovhang on the shaft 3l, as a` unit, then; by means of the universal joint 30, they are allowed to swing. and seek any new axis of rotation, due to the articles being not uniformly arranged in the basket 33, Figure l. r

In Figure 5, al free wheeling? or over-running clutch FW is provided in the pulley 20, in order to further eliminate any vibration ofthe extractor 32l being carried back to the motor 2, and thus set-up a series of vibration frequencies Working against the driving impulses o-f the motor 2. When the extraction cycle is completed, the operator cuts off the motorjcurrent and releases the pedal I'I, by depressingthe latch 49, thus engaging the clutches I2 and I0, said clutches now acting as a brake to stop the extractor. Any

. free wheeling or over-running clutch may be used and the construction of the over-running .clutch forms no part o! the invention. The free wheel ing clutch is here shown diagrammatically and the operation is'as follows: With the parts run-v ning in the direction of, the arrows and the inner part being.` the 'driver, the rotation of the inner part moves the shiftable roller R forwardly, with respect to the directionof rotation, in the contractedspace between a cam C on one side of the outer member and the periphery of the hub of the inner member, causing the inner member to drive the outer member. The roller is urged into wedging position, that is, the contracted portion of said space, by a spring S.
