WASHING- MACHINE -slipncat'ion'ma February 16,19. semina. 9,6.
The present invention relates to washing machines and has for its object to provide a device of this character which embodies novel i features of construction, whereby the clothes receiving drum or basket' is mounted in such a ymanner that it can either be swung up4` wardly into an upright position and`rapidly rotated about a vertical axisto centrifugally 'expel moisture from the contents thereof, or swung downwardly tol permit of the clothes being acted upon by a Huid in a .tub or compartment.
Among the objects of the invention are to provide a washing machine of this character which admits of the clothes receiving druml or basket being readily moved into either a washing position or-a' drying position and which provides for spinning the drum at a high rate of speed when it is in an upright -position and oscillating it at acomparatively low speed when it is swung downwardly into a tub compartment. f
The invention also contemplates a mounting of the drum which enables itto have a vieldable universal swaying movement when Y it is held in an upright position. This permits the drum to'bear down upon one side or the other when the load is being placed there? in, according to the disposition of the weight 3o of the material, and the operator is thereby enabled to distribute the clothes within the drum so as to substantially balance the same. The yieldable universal swaying movement of the drum also enables the drum, when driven at a high'rate of speed, to rotate and gyrate about its true center of gravity. I The term true center of gravity as used in this application refers to the center of support of the drum at the yi eldable connection between 40 the drum and shaft, on which the drum can Vsway when unevenly loaded, and about which the drum can oscillate and gyrate during'rotation of the drum, so that-the drum may balance itself during. the drying operation,
thereby' reducing vibration to a minimum and relieving theshaft and bearings of excessive strains. -By thus mount-ing the drum so that it is permitted to have a yieldable universal swaying movement the machine is enabled to t perform its orifices without shocks and jars and unnecessary wear upon the journals and bearings. v v
The invention also' contemplates the provision of a construction in whichthe clothes or fabrics being treated can .be washed and rinsed or washed, rinsed and blued without being removed from the drum until after the' several operations have been completed.
While certain forms and embodiments of .the invention have been shown and described in detail for illustrative purposes, it willbe understood that 'many modifications andV l changes can be made in the details of construction without departing from the spirit of thev invention. ,65 The construction of the drum, and features of the drive for the drum areclaimed in application 47,205 filed by me July 3l, 1925.

lorresponding and like parts are referred to 1n the following description and ,indicated on all ofthe views of the drawings by like the bottom of the drum and the drum shaft referencecharacters.
Referring toFigures 1 and 2 of the draw- 1ngs,the.numeral 1 designates a tub which is supported 1n an elevated position by the legs 2 and which has the lower portion thereof subdivlded by. a transverse' partitionS into two separate compartments A and B. iThese compartments are adapted to contain dil'er-l ent iluidswith which the clothes or fabrics are to be treated. For illustrative .purposes it may be considered that the compartment A containsv a' cleansing fluid such as soapy water, while" the compartment B ,contains rinsing water. A chamber C is arranged under the compartments A andB and contains the gearing .which is employed for rotating the drive shaft to'actuate the drum in the required manner.
A clothes receiving drum 4 has perforated sidewalls and is mounted upon a drum shaft u 5 whichex'tends throughthe axis thereof. of the drum is provided at the central'pcrtion'fthereof with a raised portion rovides a substantially joint packing washers 7 of rubber or the hke are applied to the drum shaft and held ti htly against the upper and lower faces o the raised portion of the drum bottom by means of nuts v8 which are threaded pn the shaft.
-The edges of the drum bottommay have de- `11 which is adapted to enter an opening inthe upper edge of the drum, and at the opposlte side thereof with a sliding latch 12'1which'is adapted to lockfthe cover on the drum. The edges of the.cover may also be provided with notches 14 which interlockwith corresponding projections on the tub so"th`at the cover may be utilized as a meansfor obtaining'a driving connection between the'shaft and the drum. The central-portion of the cover has a polygonal opening 15 which engages a corresponding polygonal portion 16* on the drum shaft, so that the cover is locked to rotate with the sha-ft when itis in position. It will be obvious that when the cover 10 is removed from position the drited universal tilting movement about the y yieldable connection with the drum shaft which is provided by the rubber washer members 7 However, when the cover 10 is placed shaft is: 'extends through the @er of this' raised portionland in order to obtain a t' ht` is free to have a limin position itnot only provides a locking conncction between the drum and the drum shaft, but also 4prevents'the yield/able joint between from functioning to permit a tilting movement of the drum relative to the drum shaft. When the drum is beingl spun in an upright position to centrifugally dry the clothes the tilting movement is desirable and the cover 10 is preferably removed. When the drum is thus being spun in an uprightpos'ition the frictional engagement between the 4drum shaft and the drum at the yieldable joint is sutlcient to obtain a driving connection between the arts, because there is no successive elevatlng and dropping vofthe contents of the drum by the action of the baie platesy 29.' When the'drumis swung downwardly -into one of the compartmentsthe cover-10 is placed inv osition to hold the contents ofthe drum in p ace andlock the drum against any tilting movement relative to the drum shaft.
In thelowered position of the drum the cover is'also vdesirable toA provide a locking connection between the-drum and the 'drum shaft, because the baiiie plates'29 then act to successively elevate and drop the clothes a's 'the drum revolves, 'thereby placing a greater TheV lower end of thedrum Vshaft extends downwardly below the bottom of the drum and has a semi-spherical friction head ap. plied thereto. When the drum is in an upright position the rounded end ofthe head fits in a depression 17 in the top of a' driv-` ing head 18 which Vis applied' to the upper end of a substantially vertical drive shaft 19, said shaft being j ournaled in a bearing sleeve 2O which is arranged at the middle portion of the partition 3. A polygonal stud 21l projects from the friction head 16 of the drum shaft and is adapted to enter a polygonal pocket 22 in the base of the depression 17 in the driving head. As shown clearly by Figure 8 the stud 21 has a cross section which is somewhat less than the pocket 22, so that the stud can have a limited amount of play within the pocket, although the polygonal base ofthe stud and pocket produces an interlocln'ng connection between the drive shaft and drum shaft so that the two shafts must rotate in unison. The play of the stud 21 in the'depression 17 as the drum tilts to one'- side or the other side. This tilting of the 'drum is of assistance to the operator in distributing the clothes or fabric within the drum so as to obtain an even loading thereof, and also enables the-axis of the drum and load to tend to assume a vertical position when i being rapidly rotated to'expel moisture from the contents thereof by centrifugal force, even though the floor upon which the washing machine rests is not level and the drive shaft is not `exactly vertical. This would serve to reduce the vibration and relieve the bearings of excessive strain. y
The base of the pocket 22is shown as provided with an elastic buffer member 23 of rubber or like material which engages the lower end of the stud 21 and tendsto position the stud at the center of the pocket. However, the buifer is elastic and will yield to any force sufcient to partially compress the same.. Unnecessary looseness and play of the drum is thereby preventedalthough the drum is not held-rigidly in positionf'and can have av limited swaying movement in any direction.
-. A bearing member 24 is loosely applied to ythe drum shaft 5 andengages a guide-way 25 in a spider 26 which is arranged Vover the driving head 18, vsaid spider'beingsupported rigidly in position. When it ijs desire-d Vto swing the drum' downwardly to subject the contents thereof to the action of the fluid in one of the tub compartments, the drum is first lifted a suiiicient amount to disengage the stud 21 from the pocket 22, after which the drum is swung to one side and lowered into the desired compartment. rlhe end of the drum shaft 5 then engages a notched bearing 27 at the side ,of the tub so that'the outer end of the drum is properly supported and the periphery of the friction head 16 then rests upon the upper surface of the driving head 18, so that the two members 16 and 18 provide a friction gear connection between the drive shaftand the drum shaft. The
drum shaft is provided with a stop collar 28 which loosely engages the bearing member 24' and cooperates therewith to prevent longitudinal movement of the drum shaft toward the center of the tub. The drum is thus properly supported in a lowered position with the axis thereof substantially horizontal, andl a driving connection is provided between the drum .and the drive shaft.
When the drum is swung downwardly into a horizontal position it is partially submerged in the fluid so that the clothes or fabrics within the drum will be acted upon by the fluid when the drum is oscillated in the usual man.- ner. In order to facilitate this action the interior of the drum is provided at the periphery thereof with the balile `plates 29. The spider 26 may be supported in any suitable manner and is shown as'secured to a frame or cage 30 which is mounted upon the upper end of the bearing sleeve 20.
The spider or guide member 26 which is shownby Figure 6 has a guide-way 25 extending diametrically across the same and is intended to be used with a tubhaving two compartments,fsuch as that illustrated by Figures 1 and 2. A modified form of spiderA tion and is provided at the lower end thereofwith a sliding pinion 31 which is keyed thereon. TheA pinion is provided with an arm 31a projecting into the central Vopening thereof and sliding within a longitudinal slot 32 loo in the drive shaft. This arm 31a is connected i to a gear shifting rod 33 whichextends upwardly through the tubular shaft and is engaged by the stud 21 .of the friction head 16 when the drum is in an upright position. The sliding p'inion 31 is then pushed downwardly against the action of a coil spring 34 which surrounds the drive shaft and is interposedbetween the pinion and a collar 35 on the drive shaft; When the pinion 31 is thus moved downwardly it meshes with a gear 36 andwhen the pinion is permitted to move upwardly it disengages itself from the gear 36 and' engages a toothed segment 37. The
gear wheel 36 meshes with an intermediate i imparted thereto, while ythe gear wheel 36 is rotated continuously in one direction. When the drum 4 is swung upwardly with the axis thereof in a vertical position the gear shifting rod 33 is -forced downwardly to slide the pinion 31 into engagement with the gear wheel 36 and the ratio of the gearing is such that the shaft-and drum will then be rotated at a high lrate of speed, thereby expelling any water from the clothes or fabric within the drum by centrifugal force. When the drum is swung downwardly to bring the axis thereof into a horizontal position, as indicated by dotted lines on Figure 2, the gear shifting rod 33 is permitted to move upwardly and the spring 34 slides the pinion 31 into engagement with the toothedsegment 37. The drum is then oscillated back and forth at a much slower rate of speed. The shifting of the gears may, of course, be accomplished in any suitable manner and the exact mechanism for accomplishing this result isnotmaterial to the present invention. I' l ,A drain plate 46 is arranged within the tuband has one diameter which is greater than the. diameter of the tub, so that it rests i on the sides'of the tub in an inclined position, where it is held by the partition 3 and frame 30, about which it is adapted to be rotated over either one of the -compartments A or B. `A handle 47 extends upwardly from a marginal portion of lthe drain plate and the drain -plate is preferably4 inclined so that any liquid falling Aupon the same will be drained into the uncovered compartment. The fluid expelled from the clothes or fabrics while the latter are being centrifugally dried will thus be conveyed back into the tub compartment from-which it was originally taken.
A modified form of the Ainvention is shown by Figure 10, in which the drum is adapted to be mounted upon and driven by any selected one of a plurality of shafts. The drive shaft 48 is journaled in a bearing 49 which has an enlargement 50 at the upper end thereof. A cage 51 extends over and around the enlargementv50 and is supported ona plate 52 secured'to the bearing. The cage is provided at the top thereof with a bearing 53 .receiving the drive shaft 48, and the opposite sides thereof with auxiliary bearings 54l receiving 'inclined shafts 55. The inner ends of these lateral or inclined shafts 55 are journaledin all of the shafts arev bearings formed in the enlargement 50 of the i main bearing so'that thelateral shafts are sturdily mounted and can carry a heavy loa'd. y
The inner ends of the lateral shaftsare provided with gear wheels 56 which mesh l.with a pinion 57 on the main drive shaft 48-'so that geared together to rotate in unison.
vThe upper end of the drive shaft 48 has a polygonal cross section and is loosely received in a socket 58 formed in the bottom-of a disc 59 which normallyhas ,the lower face there. of slightly spaced from a'stop flangel 60 on the drive' shaft. The top of the` disc 59 is formed witha 'polygonal stud 61 Iwhich is detachably engaged by a socket member 62 at the lower end of a drum shaftv5 which is rigid with the drum. The'drum' is mounted upon the disc 59 when it is in an "upright position-and is intended to be rapidlyrotated to centrifugally dry the clothes, and owing p the socket 62 is then brought into engagement with the polygonal outer end of one of the lateral shafts 55. The drum then assumes one of the dotted line positions indicated by Figure 10, and the arrangement within the tub may be such that the drum is then partially submerged in the fluid with which'the clothes are to be treated. Any suitablev means maybe lprovided for operating the drive shaft in the proper manner when the drum is in the different positions. When the drum is elevated with the axis thereof substantially vertical, it will be driven at a high rate of speed to centrifugally dry the contents thereof, while when the drum is in one of the dotted line positions it is preferably voperated at a much lower rate of speed and revolves alternately in reverse directions. Any suitable means may be provided for imparting the necessary motion to the drive shaft.
A different modification is illustrated by Figure 11, in which the upright drive shaft is designated by the numeral 63, said shaft being journaled in a suitable bearing 64. The drive shaft extends upwardly above the bearing and terminates in-a substantially semi- 4spherical friction head 65 which has a polygonal socket 66 in the top thereof. The drum 4 has a cone shaped raised portion 67 in the Y and then tilted laterally to bring the friction Y Yeo lis adapted tobe received the socket 66 the purpose of subjecting the contents thereof.
to the action of a fluid, the drum is lifted to. disengage the stud 68 from the socket 66 head into engagement with the concave wall 70 of the friction ring 69. The outer face lof the friction gear ring then rests against a friction pinion 71 which is rigid with the drive shaft 63. The cover of the drum is provided with a stub shaft 72 which engages a bearing 73 at one side of the tub and serves both to support'the outer end of the tub and to prevent the tub from swinging around on the drive shaft as an axis. The drive shaft can be suitably rotated to impart the desired movement to the drum, the friction head and friction pinion engaging op posite sides of the friction gear ring 69, so that a driving connection is obtained between the shaft and the drum.
A further modification is shown by'Figure 12, in which thev up'per e'nd of the tubular shaft 74 is provided with a cup shaped head 75 which has a pocket 76 inthe bottom thereof.V The drum 4 has a raised portion 77 at the center of the bottom thereof and is provided with a drum shaft 78 which extends downwardly below the bottom of theV drum and is disposed at the axis thereof. The shaft 78 Vis rigidly connected to the drum and an internal web 7 9 may extend across the hollow interior of the raised portion 7 and' engage the shaft for assistance in obtaining a rigid connection between the shaft andthe drum. The lower end of the drum shaft terminates in a friction ballv80 which is received within the pocket 76 in the bottom of the depression in the driving head 75 when the drum is in an upright position. Just above the friction ball 80 the drum shaft is provided with an enlarged portion 81 which is engaged by a. louder ring 82 of rubber or similar elastic material which-is `arranged at the upper end of the pocket or recess 76. The lower end of the drum shaft is removably received within the pocket when the drum is supported in an pright position with the axis thereof disi 'ip-[olsed vertically and the ball 80 then has a `ctional engagement with the walls of thepocket while the enlarged portion 81 of the Vsh ft-is engaged by the bud/,er ring 82 to hold.
the drumY resiliently in position; VThe drum shaft thus has a frictional engagement with the drive shaft'so that the drum can be driven from thedrive shaft, although the drum can rotate independently of the drive shaft when starting or stopping so that sudden shocksand jars are avoided. The rubber buffer ring 82 holds the drum shaft resiliently in an Aupright position, although the drum shaft has a limited universal movement and can be tilted in any direction by compressing the buffer ring. If the machine is not level and the driving shaft is slightly out of a vertical position the buffer ring 82 will yield and permit the drum shaft to assume a'vertical position when the drum is being rapidly rotated to centrifugally expel moisture from the contentsl thereof.
A friction ring 83 is arranged within the mouth of the cup shaped drive head 75 land this ring has upper and lower concave friction surfaces 83a. is formed upon' the drum shaft 78 and the "distance between the two friction balls 84 and 80 is equal to the diameter of the friction ring 83. When it is desired to oscillate 'the drum with thek axis thereof swung downwardly int-o a substantially horizontal position, the drum is lifted to 'disengaged the lower end of the drum shaft from the pocket 76 and then swung downwardly into the position indicated by dotted lines on Figure 12. The
friction ball- 80 then engages the lower concave friction surface 83a of the friction ring 83, while the other friction ball 84 of the drum shaft .engages the upper concave friction surface of the friction ring at a diametrically opposite point on the friction ring.
-The drum'is thus supportedbythe engagement of the friction balls on the 'drumshaft with the upper and lower surfaces of the friction ring 83. The cover of the drum may be provided with a stub shaft 85 which engages a notched bearing 86 on the side of the tub to prevent the drum from rotating bodily around the upright drive shaft. The universal engagement between the friction ring A second friction ball 84 y 83 and the two friction balls 8O and 84 of the drum shaft will serve to importrotary motion from the head 75 of the drive shaft to the drum shaft and drum, and the mechanism for driving the main shaft 74 may be such that the shaft can be spun at a high rate of speed when the drum is swung upwardly and the contents thereof will be centrifugally dried, and oscillated at a compararA tively low rate of speed when the drum is swung downwardly and partially submerged in the liuid contents of a tub compartment. l
`The gearing mayjbe controlled by a. gear shifting rod 33 which is arranged within the ,tubular main shaft, just as described in connection with the embodimentl of the lnven tion shown by Fig. 2. y
Referring again to the construction shown by Figs. .2 and the cover 10 may be removed from the drum .when the drum 1s being spunlin` an upright the contents Therubber position to expel moisture .from thereof by centrifugal force.
12:5` i 5, it may 'be explained that washerv members 7 -then provide' a resilient connection between the drum and the drum shaft so that the 'drum can have a limitedl tilting movement about the drum shaft and assume -a balanced position thereon. The drum -can thus have a limited tilting movement with respect to the drum shaft, and
the drumshaft, as previously explained, has a limited tilting movement with respect to the main drive shaft, so that thedrum can adjust itself when'driven at a high rate of s eed to bring the center of gravity o f the um and load over the vertical axis, and
- thereby reduce friction and strains to a minimum. The baiiie platesv 29, which are arranged around the inside peri hery of the drum, are preferably wide at t e topof the drum and taperor 'decrease in width toward the bottom ofthe drum so as to minimize the possibility of the clothes or fabric within the drum being torn when the drum is rapidly rotated to centrifugally dry the same. As
indicated by Fig. l, the interior partition 3 of the tub is preferably hollow so as to provide an air space or vacuum between the spaced side walls thereof. This enables the different compartments of the tub to contain fluids at 'dierent temperatures without the heat from the fluid in one of the compartments being quickly conducted through the partition into'the fluid in another compartment. When washing clothes itis frequentv ly desirable to have cold water in one tub compartment and hotswater 'in another tub compartment and this is ossible where the ,partition 3 has a hollow ormation so as to provide a dead air space or a vacuum space.
When washing clothes or fabrics in a. rotating drum there is a tendency for the clothes or fabrics to roll up into a ball or balls if the it is not necessary that the drum alternate in its direction of rotation to prevent the rolling up of the clothes, since the substantially triangular baille plates 29 pick up the clothes an'd carry them out of the water, the clothes having a tendency to slide toward the narrow end of the baiile-plates as they are being carried up, due to the inclination of the drum. After being carried u by the bailie plates the clothes slide oi an drop on the conical projection in the center of the drum, and they then slide over the walls of the cone and drop upon the lower portion of the drum. The triangular bale plates and conical projection within the drum thus coopcrate with each other to cause the clothes to slide against the respective members, hitting the cone first and then the liquid after being dropped from the top of the drum, thus hitting twice each time they are carried up and dropped and sliding instead of rolling oi the obstruction. This tends to prevent the clothes or fabrics from rolling up into a ball or balls, so that if it is desirable a drum constructed in. this manner may be rotated continuously in one direction while the clothes are being subjected to the action of the cleansing fluid.
