(01. 68-—15) Fig. 7 is a section of the ?exible coupling on This invention relates to domestic washing machines of the type in which the water con tained in a tank or the like, in which the clothes 7 are being washed, is agitated either by hand or 5 mechanically. In the usual arrangements, the machine comprises a tank or container, with or without various rubbing abutments or corruga tions on the sides, a central vertical spindle be ing adapted to carry an agitator of suitable form 10 which is immersed in the water and amongst the clothes. These known arrangements possess certain drawbacks, particularly as regards the diiliculty of providing proper bearings for the spindle, l5 straining of the clothes by lubricant, rust or so called verdigris, and the interference of the un derneath operating mechanism with devices for heating by gas or the like. ' It is one object of the present invention to avoid those disadvantages and at the same time 20 to provide a simple, e?icient and reliable washing machine intended for domestic use. Another object is to provide a turntable device between the tank and its support which device whilst allowing the tank to be freely oscillated does not 25 interfere with the heating of the tank from un derneath. I employ a tank or container arranged for oscillation on a vertical axis and provided with the motor shaft. Fig. 8 is an elevation of the reduction gearbox in vertical section on the axes of the shafts. " _ Fig. 9 is a longitudinal section and Fig. 10 a 5 transverse section of the reversing gearbox for driving the wringer. Fig. 11 is a plan of a modi?ed buffer device for the driving of the oscillating tank. ‘ Fig. 12 is a vertical section on the line |2—-|2 10 of Fig. 11, on an enlarged scale. Fig. 13 is a fragmentary view of a detail of construction showing the form of certain slots. As shown in Figs. 1 and 2, the washing ma chine is constructed in the form of a cabinet. 16 made of pressed steel or the like, preferably ?n ished in vitreous enamel, the cabinet being of rectangular shape, with four ?at sides or panels In, four legs “fitted with moulded rubber feet l2, and a top l3; the sides, legs and top are se- 20 cured together by concealed bolts l4, and the legs are reinforced by angular metal straps I5 for supporting the heavy parts in the interior of the cabinet. Carried approximately half-way down the 25 cabinet, and secured to the upper ends of the straps I5, is a‘press‘ed steel base-plate l6 form ing a central bracing for the body of the cabinet and having a large circular opening of which the 30 agitator paddles or the like moving with the tank, the tank being mounted on an annular bearing track or turn-table with an open center, periphery is shaped to form a cup or ball-race I1, 30 35 the tank and in the open center of the bearing a turn-table. The inner periphery of the ro- 35 tatable plate I9 is ?tted with a number of safety catches 2| adapted to engage under the station ary ball race I‘! to prevent the two plates from ?tted with caged balls l8. Upon this ball bearing there is rotatably mounted an annular pressed and a gas burner or other means for heatingv steel plate /,I9 forming a complementary ball race the water being placed beneath the bottom of or cone 20,; so that the two plates l6, lfcbnstitute track or turn-table. Preferably the washing machine is provided with means for power operation, a wringer or the like accommodated upon the washing ma 40 chine being also driven by power from the same source when desired. The invention is hereafter more fully de scribed with reference to the accompanying drawings, in which: .15 Fig. 1 is a part sectional elevation of the ma chine in the preferred embodiment. Fig. 2 is a part side elevation showing the top cover in use as a rinsing bath. Figs. 3 and 4 are details of a stand seen in 50 Fig. 2. Fig. 5 shows the stand folded ?at and hanging against the rear panel of the machine. Fig. 6 is a detail in section on the line 6-6 of Fig. 1, showing the mounting for the driving 55 motor. separating during normal operation. The upper flat portion 22 of the plate l9 has blocks 23 spaced 40 at intervals round its circumference and secured by bolts 24, the rim of the plate being ?anged upwards at 25 outside these blocks, upon which there rests an open-topped cylindrical tank 26, constructed of sheet metal; the peripheral ?ange 45 25 of the plate 19 forms a guide to facilitate the centering of the tank thereon and to hold it in position during operation, but allowing the tank to be lifted completely out for cleaning, or for use as a separate boiler, or for other purposes. Addi- 50 tional guide arms 21 may also be provided as shown, these arms being engaged under the blocks 23 and secured by the same bolts 24. The open top of the tank 26 has a ?anged rim Z5 doubled, back inwards to provide a bead 29 56 2 2,112,584 upon which a domed lid 38 can rest, a handle 3| being provided for lifting and replacing" the lid. The ?anged rim 28 overhangs the top l3 of the of the rubber coupling 55 is of substantially spherical form, with two cylindrical extensions 51 having! metal ferrules thereon, these exten cabinet, in which an opening is formed with a beaded or flanged edge 32, leaving a clear passage sions being of oblong section internally so as to engage with the ends of the respective shafts 48 round the tank and beneath the rim 28. The and 56, as seen in Fig. '7. The low-speed driven tank is provided internally with a plurality of shaft 58 of the gearbox 58 carries at its lower vertical paddles or vanes 33, which as shown are integral with the arms of a spider 34 resting on end an external crank 58 driving a connecting rod .68 which transmits oscillatory motion to. the rotatable plate I8 supporting the tank; bu?er I0 springs are preferably arranged to cushion the shocks at the reversal of motion, this being done for example, as shown in Fig. 1, by providing a bridge 6| between two points on the inner pe 10 the bottom- of the tank. The clothes placed in the tank for washing are therefore held away from the bottom of the tank by the~ paddles mounted on or near the bottom, and the clothes may be boiled while the agitation is taking place. 15 The spider 34 has its arms forked at their extrem ities to engage with radial driving lugs 35 of tri angular shape, having integral ?anges riveted or soldered to the walls of the tank. The spider 34 can thus be readily lifted out of place, leaving 20 a plain tank which can be used as an ordinary boiler when so desired, the spider being subse quently re?tted by engaging its arms with the driving lugs 35. If desired, the detachable lid 38 may be pro~ K1 CH vided with paddles or stirrers as indicated at 36, consisting for example of non-rusting metal tubes closed‘ at their lower ends; the lid 38 is arranged to ?t su?iciently tightly in the bead 29 to prevent slip during the oscillation. 30 Beneath the tank and projecting into the cen tral opening of the annular plate I8, there is mounted a gas burner 38, fed by a connection at 381, this burner being supported by a cross-bar 39 having its ends turned up and cranked out wards for attachment to the base-plate l6 as indicated in dotted lines at 48. A shallow tray‘ 4| is provided beneath the burner in order to collect condensation water, the edges of. this tray having a tight fit upon the turned-up ends of the cross bar 39. The outer end of the burner tube 42 is also supported by a stay 43 secured to the periphery 44 of the base-plate I6, and is provided with the usual adjusting sleeve 45 for regulating the air supply to the burner; an oval opening 48 in the side panel I8 through which the gas-connection 381 extends, allows this sleeve to be adjusted, a similar opening or openings 41 being provided in one or more of the other pan riphery of the plate I9, and mounting a vertical ' pin 82 thereon, the connecting rod 68 being at tached to this pin 62 by a stirrup 83, with springs 64 inserted between the stirrup and the nuts 65 on the connecting rod. The shaft 58 is con trolled axially by a rod 66 extending up through 20 a guide 6'! in the top I3 of the cabinet and pro vided with a knob 68 by means of which the shaft can be lifted so as to disengage the drive, as hereafter explained, the shaft being then ‘re tained in this disengaged position by turning 25 the knob 68 so that a cross-pin 68 rests on the upper edge of the guide'G‘I; in order to re-en gage the drive, the knob 684 is turned to drop the . pin 69 into its notch ‘I8 in guide 61. A second low-speed driven shaft ‘II extends up 30 from the gearbox 58, in axial alignment with the motor shaft 48, in order to drive an ac cessory such as a wringer ‘I2, which is mounted above the top l3 of the cabinet; power is con veyed to the wringer through a gearbox ‘I3 pro vidingfor reversal and interruption of the drive. and also allowing the wringer to be swung about a vertical axis in line with the shaft ‘II, the wringer being supported from the gearboxv ‘I3 as hereafter described. ~ In the position shown in Figs. 1 and 2, the wringer ‘I2 is adapted to operate on clothes lift ed out of the tank 26, such clothes passing through the rollers ‘I4 and being received at the back of the machine; as shown in Fig. 2, a rins ing bath ‘I5 is provided into which the clothes are run, this bath being supported on a col els I8 to allow of lighting and viewing the gas lapsible stand. The latter comprises two legs or uprights ‘I6 each having a' bearer ‘I‘I hinged ?ame. thereto upon a bar ‘I8 which forms a spacer be The combustion gases pass between the blocks 23 and upwards around the tank 26, emerging through the opening in the top I3 of the cabinet beneath the rim 28 of the tank. The power unit comprises an electric motor 48 with vertical shaft 48 ?exibly coupled to a gearbox 58, which is mounted upon the base plate I6 over a second circular opening in the latter; one of the rear legs II, with its reinforcing strap I5, forms in efl’ect a bed-plate for the power unit, the motor 48 being bolted to this leg over the lower end of the strap, while the base plate I_ 6 is bolted to all the four legs at the upper ends of the respective straps I5. As seen in Fig. 6, the motor 48 has a ?at face 5I secured to 65 a bracket 52 shaped to engage the angularrstrap I5, 0. single bolt 53 holding the bracket 52 in place; thusthe motor can easily be removed for inspection or repair, and a motor of any par ticular type or voltage can be ?tted to suit the available supply of current. The motor shaft 49 has its upper end formed with two' opposite ?at faces 54 whereby it has a readily detach able driving engagement with a moulded rubber coupling 55 which is similarly engaged with the primary shaft 56 of the gearbox 58; the center 40 tween the uprights and a wooden block 88 at tached thereto above the bar ‘I8; a second spacer bar ‘I9 is fitted between the lower ends of the uprights, the bath ‘I5 being mounted on the bearers 11, between the blocks 88 and the back of the cabinet. When in use, the stand is con nected to the cabinet by hooking the free ends of the bearers ‘I.‘I upon pegs 8| projecting from the rear panel I8, the bearers being provided with shoes 82 (see Figs. 3 and 4) suitably notched at 60 83 for connectionto the pegs; when the stand is not required, the bearers are detached from the pegs 8| and folded down against the up rights ‘I6, the folded stand being then turned round and mounted ?at against the rear panel 65 I8 (as shown in Fig. 5) by hooking on to the pegs 8| and also on to similar pegs 84 at a lower level, for which purpose keyhole slots 85 (as shown in Fig. 13) are formed in the uprights. The bath ‘I5 may be arranged to form a cover 70 for the cabinet when not in use, the bath being then inverted as indicated at ‘I51 in Fig. 2; the wringer ‘I2 is adapted to fold down ?at on the top of the cabinet as indicated at ‘I21 in Fig. 2, so as to ?t inside the inverted bath. 75 2,118,584 The gearbox 50 is illustrated in Fig. 8, from which it can be seen that the primary shaft 58 carries a pinion 86 meshing with a large gear wheel 81 integral with a pinion 88 and rotat able upon a stud 89 mounted in the bottom of the box; the pinion 88 meshes on one side with a large ‘gear wheel 90 ‘having its hub 9| sup ported in a bearing 92 in the top of the gear box, this hub providing a bearing for the driven of the spigot member I08, which forms a bearing for a bevel pinion I2I having the bore of its hub I22 shaped to‘ engage the ?at faces II8 on the shaft 1 I. The pinion I2I is ‘adapted to mesh with one or the other of two bevel wheels I23, I24, slidably mounted upon a horizontal shaft I25 in the upper part of the gearbox 13; one end of this shaft is reduced at I28 to take a bearing in a boss I21 in one of the ends of the box, while the other end of the shaft is formed with 10 two opposite ?at faces I28 and is engaged in a correspondingly shaped hole I29 in a bushing I30 rotatably journaled in the other end of the gearbox. The two bevel wheels I23, I24 are ?tted with a single key I3I, slidable along a key 15 way I32 in the shaft, and they are connected to gether as regards axial ‘motion by a bridge piece I33 having two parallel semi-circular ribs I34, the end of the shaft 58, so that while the gear , which engage in two circumferential grooves I35, one. on each wheel; the ?at top I38 of the 20 wheel 90 is rotating, the knob 68 of the control bridge piece I33 is slotted at I31 and is engaged rod 68 can be operated to lift the shaft 58 and thereby disengage the clutch member 94 from the by a gear-shift crank I38 with an eccentric or crank pin I39 entering the slot I31. The ver hub 9| of the wheel, the necessary axial move ment of the driven shaft 58 being allowed by tical spindle I40 of this shift-crank is rotatably mounted in a boss I4I at the top of the gearbox, clearance between the lower bearing 93 and its projecting end I42 being squared and ?tted the crank 59. The pinion 88 also meshes with another large with a lever or handle I43, retained by a screw I44 and washer I45. The boss I48 of the lever gear wheel 99 in axial alignment with the driv I43 is formed with teeth I41 engaging with a ing shaft 56, this gear wheel having its hub I00 stop-pin I48 to one side of the boss I“ in order 30 30 supported in a bearing IOI in the top of the gearbox; the hub I00 is formed with dogs I02 to limit the turning movement of the handle; a latching ball I49, backed by a spring I50, is engaging with a clutch member I03 secured upon the second low speed shaft H which drives the mounted in a hole I5I in the boss “I, the inner face of the- lever boss I48 being formed with wringer 12 through the medium of the reversing gear-box 13. The shaft TI is driven constantly shallow pits I 52 for engagement by the latch 35 so long as the motor 48 is running, the operation ing ball I49 in de?nite positions of the handle I43. In Fig. 9, the two bevel wheels I23, I24 of the wringer being controlled by the gearbox 13, as hereafter described; the speed of this shaft are out of mesh with the pinion I 2| upon the 1I, due to the reduction in the gearbox 50, may shaft 1|; this neutral position represents the middle position of the lever handle I43; by turn 40 40 be for example 70 revolutions per minute with ing the latter in one direction or the other, one a motor speed of 1425 revolutions per minute, and the speed of the shaft '58 (when coupled by or other of the bevel wheels I23, I24 can be brought into mesh with the pinion I2I, so as the clutch member 94) may also be 70 revolu tions per minute. The several pinions and gear to drive the shaft I25 and bush I30 in the for wheels are preferably immersed in oil contained ward or in the reverse direction, the movement 45 in the gearbox, the top of the box being ?tted of the spindle I40 being communicated by the eccentric pin I39 to the bridge piece I33 which in an oil-tight manner and secured by studs I04; shifts the bevel gears “I23, I24 accordingly. a detachable cap I05 is provided on the top, At the end supporting the bush I30, the gear over the stud 89, for re?lling the gearbox with box 13 is provided with a vertical web I53 against oil when necessary. The reversing gearbox ‘I3 is illustrated in Figs. which a pair of bracket plates I54 are secured by 9 and 10, from which it can be seen that the bolts I55, these brackets being-arranged to carry cabinet top I3 is ?tted with a spigot member the wringer 12 with one of its rollers 14 in line with the driven shaft I25; the spindle I56 of this I06 upon which the box 13 is mounted, the mem ber I06 being- secured by bolts I01 passing roller is extended into the bush I30, the end of the spindle being formed with two opposite ?at through an annular washer plate I08 on the in side of the cabinet. The gear box 13 comprises faces I51 for taking the drive. Upon releasing the clamping lever II8, the spigot mounting of a base I09 to which the upper part of the box is hinged upon a pivot IIO along one side, the the gearbox 13 allows the latter to be revolved about the axis of the vertical shaft 1I, together GO 60 base having along its opposite side a vertical with the wringer 12,‘ so that the latter can be ?ange III through ,which a locking screw II2 with conical point II3 enters a hole H4 in the brought to a position for use between the wash ing tank 25 and rinsing bath 15, or to a posi , corresponding side of the gearbox, so as to hold the latter rigid with the base I09; the latter is tion at right angles thereto for use between the provided with a vertical socket II5 surrounding rinsing bath and a table or basket; in each of the spigot member I05, the socket being split these positions the reversing gearbox enables radially at H0 and provided with a clamping the wringer to be driven in either direction or to be stopped at will.
