The machine which is shown in the drawings constitutes the preferred form or embodiment of the invention. It is primarily designed for I the power mechanism back and forth between a normal operating position and a discharging position, and means 20 for'supplying the outer shell with a washing fluid, such as water, when the outer shell is in its normal operating position.

The supporting structure I is adapted to rest on, and be 'flxedly secured to, the floor of the laundry or other establishment in which the washing machine is used. It remains stationary when in use and consists of a pair of laterally spaced U-shaped standards 2| and 22 and a plurality of tie rods 23 between the two standards. The two standards are positioned in horizontal alignment and embody base portions 24, upstanding front arms 25 and upstanding rear arms 26. They are preferably in the form of metallic castings and have floor engaging feet 21 on the bottom of their base portions 24. The tie rods 23 serve fixedly to space apart the two standards 2| and 22 and have the ends thereof suitably secured to the arms and base'portions of the standards. In addition to the parts heretofore mentionedthe supporting structure l5 comprises a horizontally extending shaft 28 and a bar. The shaft 23 extends between, and is fixedly connected to; the upperextremities of'the front arms 25 of the two standards. The bar 29 is disposed in parallel relation with the shaft 28 and extends between, and is suitably secured to, the upper extremities of the rear arms 26 of the standards 2| and 22.-

The outer shell I6 is positioned between the U-shaped standards 2| and 22 of the supporting structure l5 and embodies a cylindrical side wall 30 and a pair of circular or disc-like end walls 31. As shown in Figure 1 the end walls 3| are provided with inwardly extending annular flanges 32 and these extend around, and are welded or otherwise fixedly secured to, the ends of the cylindrical side wall 30. In addition to the flanges 32 .the end walls 3| are provided with centrally positioned bearings 33 and exteriorly disposed cup-shaped housings 34. The bearings 33 are disposed in circular holes 35 within the central portions of the end walls 3| and have radially extending flanges 36 which are bolted to the hole defining portions of the end walls 3|. The housings 34 serve to house the bearings 33 and are positioned centrally with respect to the end walls.

-'I'hey overlie the standards of the supporting structure and have on the free margins of their side walls radially extending flanges 31 which fit flatly against, and are bolted to, the outer faces of the end walls 3|. The outer shell I6 is adapted in connection with operation of the machine to be charged with water by way of the supply means 2|] and embodies'a dump valve 38 whereby the water may be discharged from the interior of the outer shell at the conclusion of a washing operation:

The dump valve 38 is of any suitable variety or type and isconnected to the bottom portionof the side wall 30 of the outer shell. The side wall,

aspen 3|| embodies in the front upper portion thereof a rectangular opening 39 and this is closed by a door 40. The latter is arcuate in cross section and is mounted .by-way of arcuate end tracks or guides 4| in order that it may he slid upwards and circumferentially with respect to the side wall oi the outer shell into an open position wherein it exposes the opening 39 for clothes charging and discharging purposes. The lower marginal portion of the door is provided with suitable latches for locking the door in its closed position. The front central portions of the inwardly extending flanges 32 on the end walls 3| are provided with collar-like elements 42 and these surround the ends of the shaft 23 of the supporting structure I5 and form pivotal connections for the outer shell whereby the latter is permitted to swing bodily upwards through substantially an arc of 90 into a discharging position wherein the opening in its side wall faces downwards, as shown in Figure 3. The outer shell ends of the pins when the outer shell is in its normal operating position. It is contemplated that the machine will be charged with the clothes and like articles to be washed while the outer shell is in its normal operating position and the power mechanism i8 is at rest. After charging of the machine the. mechanism I8 is set inmotion for clothes washing purposes. At the end of the clothes washing operation the power mechanism I8 is stopped and the door 40 is slid into its open position so as to expose the opening 39 in the upper front portion of the side wall 30 of the outer shell. a After sliding the door into its open position the outer shell is swung upwards and forwards into its discharging position wherein the opening 39 faces downward and permits the clothes and other articles to fall by gravity out of the outer shell. After discharge of the clothes and other articles the outer shell is swung rearwards and downwards into its normal operating position wherein it is supported as a result of the hooks resting on the inner ends of the pins 43;

The inner shell I! is disposed concentrically within the outer shell l6 and is adapted to hold the clothes and other articles during a washing operation. It is driven or rotated as hereinafter described by the power mechanism 3 and con sists of a foraminous cylindrical side wall 45 and a pair of circular or disc-like end walls 46. The end walls are positioned directly inwards of the .end walls 3| of the outer shell i6 and have outwardly extending flanges 41 which fit within,

and are welded or otherwise fixedly secured to,

outer shell. The cylindrical side wall 45 of the inner shell embodies inwardly projecting longitudinally extending ribs 49 for clothes tumbling purposes and has a rectangular opening 50. The latter is closed by a door 5| which is of arcuate aaoes cross section and has tracks or guides 52 at its ends in ordl r that it may be slid circumferentially with respect to the inner shell into an open position wherein it exposes the opening 50. By reason of the fact that the side wall of the inner shell is fora-minous the water in the outer shell is permitted to flow through the interior of the inner shell into contact with the clothes and other articles to be washed. In connection with charging of the machine the inner shell, after first opening the door 40 for the opening 39 in the outer shell, is rotated until the opening 50 in the innner shell is in registry with the opening 38.

Thereafter the door 5| is slid into its open position and the inner shell is charged with clothes and other articles to be washed. Upon closing of the doors SI and an the machine is in readiness for a washing operation.

The power mechanism l8 serves in connection with operation of the machine, to rotate the inner shell back and forth relatively to the outer shell and comprises a reversible electric motor 53 and speed reducinggearingbetweenthemotorand the inner shell. The electric motor 53 embodies a conventional solenoid brake 54 and is mounted on a bracket 55 on the housing 34 that is adjacent the stardard 2 l The speed reducing gearing constituting part oi the power mechanism l8 comprises a bevel pinion 55, a bevel gear 51, a pinion 58 and a gear'59. The bevel pinion 56 is mounted on one end of the armature shaft of the electric motor 53 and meshes with, and serves to drive, the bevel gear 51. The latter, as-shown in Figure 6, is mounted on the outer end of a horizontally extending shaft 60 which is positioned in parallel relation with the axis of the outer shell i6 and is supported by roller bearings 6|. The pinion 58 is keyed or otherwise fixedly secured to the inner end of the shaft 60 and meshes with,'

and serves to drive, the gear 59. Such gear is disposed in the housing 34 that is adjacent the standard 2| and has the hub thereof connected fixedly to the outer end of the adjacent trunnion 48. The upper portion of the housing 34 that is adjacent the standard 2| embodies an enlargement 62 which serves to house the bevel pinion 56, the bevel gear 57, the pinion 5B and also to support the bearings ii in which the shaft 60 is journailed. When the machine is in operationthe electric motor 53 is driven in one direction for a redetermined period of time and then in the opposite direction for a like period and hence causes the inner shell to rotate back and forth relatively to the outer shell. By reason of the fact that the power mechanism I8 consisting of the reversible electric motor 53 and the speed reducing gearing between the motor and the inner shell-is mounted in its entirety on the outer shell I6 it moves bodily with the outer shell in connectionwith swing of the latter back and forth between its normal operating position and its discharging position and hence it is at all times in If operative or driving relation with the inner shell regardless of the position of the outer shell.

The hydraulic system I 9 for swinging the outer shell I6 together with the inner shell I? and the power mechanism I8 backand forth between its normal operating position and its discharging position, comprises a pair of cylinder and piston devices 63 and these are located directly outwards of the standards of the supporting structure I5 and consists of cylinders 64 and pistons 65. The lower ends of the cylinders are pivotally connected to brackets 56 on the base portions 24 of the standards in order that the devices 53 connection with upward or substantially an age of are permitted to swing laterally in parallel relation with the standards. The brackets 88 are preferably in the form of metallic castings and project outwards and downwards from the base portions of the standards. They embody horizontally extending lower parts 51 and these, as best shown in Figure 6, embody pairs of spaced apart fixed bearings 58. The lower ends of the cylinders 54 are closed by fixed caps 59 which embody diametrically opposite pintles III. The latter. are joumalled in. the bearings 68 and together-with said bearings form the pivotal connections between the cylinders 64 and the brackets 55. The upper ends of the cylinders 64 are closed by means of cup shaped caps II which are connected in place by screw thread connections (not shown) and have centrally disposed stufling boxes (also not shown). The pistons 65 of the piston and cylinder devices are mounted in the cylinders 54 for longitudinal v sliding movement and embody fixedly connected upstandingpiston rods 12 through the stufling boxes in the cup shaped caps II. The upper ends of the piston rods are pivotally connected to brackets 13 on the'central portions of the housings 34 by means ofsleevelike elements I4 and pins 15. The brackets 13 are suitably attached or connected to the central portions of the housings 34 and carry the pins 15 so that they are in axial alignment with the trunnions 48 of theend walls of the inner shell II. The sleeve-like elements I4 are fixedly connected to the upper ends of the piston rods and are rotatably mounted on the pins 15, as shown in Figure 6. When fluid under pressure, such, for example, as

oil, is introduced into the lower ends of the cylinders 54 whilethe upper ends of the cylinders are vented the pistons 65 together with the piston rods 12 are caused to slide upwards and result in the outer shell I5 together with the inner shell I! and the power mechanism I8 being swung upwards and forwards from its normal operative position into its discharging position. When oil rods 12 are slid downwards and cause the outer shell together with the parts associated therewith to swing rearwards and downwards into it's normal operating position wherein it is supported by way of the pins 43 and the hooks 44. In downward sliding of the pistons and piston rods the cylinder and piston devices 63 swing laterally with the pintles 10 as articulation points. The stroke of the pistons 55 is such that the outer shell IS in connection with swing thereof, either into or out of its discharging position, swings throughout When the outer shell is in its normal operating position the trunnions 48 are horizontally aligned with the shaft 28 and when the outer shell isin its discharging position wherein the opening in the side wall thereof faces downwards the trunnions 48 are vertically aligned with said shaft '28. As a result of the fact that the trunnions 48 are in alignment with the shaft 28 when the outer shellis in its discharging position the outer shell is in sub- In addition to the cylinder and piston devices 63 the hydraulic system I9 comprises a gear pump 16, a control valve 11 and a particular pipe arrangement whereby oil under pressure may be which extend slidably ders,

It is of.

- conventional desi n and consists of a casing 18 and a, pair of meshing gears 19 in the casing. One of'the gears is connected for drive by -a uni directional electric motor 88 which is mounted on the outer wall of the base portion 24 of the standard 2| and is supplied with current by a pair of conductors 8| and 92. The conductor II groove I88 establishes communication between the ports 91 and98. Theiswitch 83 for controlling operation of the gear pump driving electric unidirectional motor 16 is disposed in the lower portion 01 the case 94 and is positioned so that the push button 88 thereof is located under the collar I8I between the lower end of the lever I88 and the outer end of the plug stem 99. The 'collar is provided at the bottom thereof with a flat I86 against which the switch button 88 abuts when includes a normally open switch 83 consisting of a pair of fixed spaced apart contacts '84 and 85 and a bridge 86 for the two contacts. The bridge v is urged away from the contacts by a compression spring 81 and has a push button 68 whereby it wherein the land I84 closes the port 96 and the land I85 closes the port 91. When the push button is in engagement with the flat'the switch 83 g is in its open position and the pump driving motor may be shifted against the force ofthe spring into a closed position wherein it 'crossconnects' the two contacts 84 and 85 and results in flow of current to the electric motor 88. When the switch 83 is in its closed position the motor 88' operates to drive the gear pump 18. The casing 18 of the pump includes an inlet 89 and an outlet port 98.

The control valve 11 is mounted on the'upper 88 is, therefore, inoperative. is rotated out of engagement with the switch When the flat I86 button 88 in connection with either clockwise or counterclockwise swinging of the lever I88, the

collar I8I operates to depress the button and hence closes the switch and results in operation hydraulicsystem I9 for swinging the outer shell I extremity of the front arm of the standard together with the inner shell and the power mechanism back and forth between its normal operating position and its discharging position comprises pipes I81, |88, I.89, 8 III, H2 and 3. One end of the pipe I81 leads to the base portion 24 of the standard 2| and the other endof the pipe I81 is connected to the inlet port 89 in the casing 18 of the gear pump 16. The base portion 24 of the standard 2| is hollow and, as

' shown in Figure 5, forms a reservoir II4 for 2.

9| of the control valve 11 has four

ports

95, 96,91

and 98; As shown in Figure 9,- the ports95 and 98 are formed in the side portions of the casing 9|, are positioned one diametrically opposite the other and lead outwards from the cylindrical bore 93. The port 96 is formed in the upper portion of the control valve casing 9| and communicates with, and leads'outwards from, the bore 93. The

fourth port, i. e., port 91, is'formed in the bottom portion of the casing 9|, communicates with the bore 93 and is positioned diametrically opposite the port 96. The plug 92 fits rotatablyv in the bore 93 and has at its outer end a stem 99 which, as shown in Figure 8, projects intothe cup shaped case 94 on the outer end of the valve casing 9|.

body or column of oil. .Said other end of the pipe I81 is so positioned that it communicates with the lower portion of the bodyor column of oil in the reservoir III. The pipe I88 extends between the gear pump 16 and the valve 9 I. One end of the pipe I88 is connected to the outlet port 98 in the gear pump casing 18 and the other end 'of-said-pi'pe is connected to the port 95 in the casing 9| of the control valve 11. The pipe I89 is connected to, and leads from, the port 96. The pipe H8 is in the form of a branch pipe.. It is An'upstandi ng lever I88 serves asa medium for v rotating the plug 92. The lower end of the lever is disposed in the case 94 and is connected to the outer end of the stem 99 by a collar I8 I. As

shown in Figure 8. the central portion of the lever extends through an arcuate slot in the .annular cylindrical side wall of the case 94. The plug 92 of the control valve embodies a pair of oppositely disposed arcuate grooves I82 and I83 and these are positioned in alignment with the ports .in the valve casing and are separated by a pair of lands I84 and I95. 7 when the lever I88 is positioned vertically in what may be termed a neutral position the landIIIl closes the port 96 and the land I85 closes the port v 91.

' two grooves are 'alsoarranged that when the lever is swung in a counterclockwise direction-from its The lands are arranged so that and has its ends connected to the lower ends of the cylinders 64 ofthe cylinder and piston devices 63. The pipe I II is connected to, and leads from, the port 91 in the control valve casing 9|. The pipe I I2 is in the form of a. branch pipe as shown in Figure 10. It is connected to the'discharge end of the pipe III and leads to the upper ends of the cylinders 64. The pipe 3 serves as a return pipe and has one end thereof connected to the port 98 and its other end leading into the reservoir I I4 in the base portion 24 of the standard 2|. When'the valve controlling lever I88 is swung in a counterclockwise direction from its neutral or vertical position so as to cause the plug groove I82 to establish communication between the

ports

95 and 96 and the groove I83 to establish commun'ication between

the'ports

91 and 98,

the switch 83 is automatically closed, as hereinf before pointed 'outgandas a result sets in operation'the motor 88 which, in turn, drives the pump 16 sov that it supplies .oil under pressure into the lower ends of the cylinders 64 via pipe I88, port 95, plug groove I82, port 96, pipe I89 and branch pipe II8. As soon as the oil under pressure is introducedinto the lower ends of the cylinder 64 the pistons 65 move upwards and operate through of the cylinders are vented and the oil above the pistons flows back to the reservoir I I4 via branch pipe II2, pipe III, port 91, groove I03, port '98 and return pipe I I3. When the lever I is swung from its neutral or vertical position in a clockwise direction as viewed in Figures"! and 10, so as to cause the plug groove I02 to establish communication between the ports and 91. and the groove I03 to establish communication between the ports 01 and 90, the switch 83 is automatically closed and sets in motion the unidirectional electric motor 80 which in turn drives the gear pump I6 so that the latter pumps oil under pressure into the upper ends of the cyinders 04 via pipe I00, port 35, groove I02, port 91, pipe III and'branch pipe II 2. Entrance of fluid under pressure into the upper ends of the cylinders 64 of the cylinder and piston devices 63 results in the pistons 55 sliding downwards and causing the outer shell I6 to swing rearwards and downwards into its nor-.

mal operating position. During downward sliding movement of the pistons in the cylinders the lower ends of the cylinders are vented and the oilbeneath the pistons flows back to the reservoir II4 via the branch pipe IIO, pipe I09, port 96, roove I03, port 98 and return pipe H3. When the control lever I00 is in its neutral position wherein the lands I04 and I05 close, respectively, the ports 06 and 91, the switch 83 is in its open position and the oil in the cylinders is locked with the result that the pistons remain stationary and hold the outer shell IS in a. fixed position. The pipe I00 between the outlet port 90 in the pump casing I0 and the port 95 in the valve casing 9| is provided with a relief valve I I5, the outlet port of which communicates with the reservoir II4 by way of a pipe I I8. In the event that excessive pressure develops in the pipe I08 as a result of the operator of the machine failing to return the lever I00 to its neutral position after the outer shell It has been swung into its discharging position or into its normal operating position the relief valve II5 opens and the oil which is pumped by the gear pump flows back into the reservoir II4 via the pipe II6.

The means 20 for supplying the outer shell I 6 with water when the outer shell is in its normal operating position comprises a T fitting Ill and a pipe section H8. The T fitting I I1 consists of a pair of aligned inlet branches H9 and I20 and an intermediate outlet branch I2I and is fixedly mounted on the central portion of the bar 29 of the supporting structure I5 so that the inlet branches are disposed in parallel relation with the outer shell I0 and the outlet branch I2I extends horizontally towards the outer shell. The inlet branch H0 of the T fitting is connected to a hot water pipe I22 by way of a valve I23 and the inlet branch I20 is connected to a cold water pipe I24 by way of a valve I25. The outerend of the outlet branch I2I of the fitting I I1 is canted so that it is inclined upwards and rearwards and has an annular groove I26 with a sealing gasket I21 therein. The pipe section I I3 is fixedly connected to the central rear portion of the side wall 30 of the outer shell I0 and communicates with the interior of the, outer shell. The outer or rear end of the pipe section "I I0 is canted so that it is inclined downwards and forwards, and is so arranged that it seats against the gasket I 21 when the outer shell I5 is in its normal operating position. As a result'of the manner in which the outer end of the outlet branch HI and the rear end of the pipe section. IIB are canted the pipe section is free to swing with the outer shell in connection with swinging of the latter into its discharging position. When the outer shell is in its normal operating position the pipe section II8 eiiects communication between the T fitting H1 and the interior of the outer shell and hence water may be introduced into the interior of the inner shell from hot water pipe l22-or cold water pipe I24, or bdth pipes.

When the outer shell I6 is in its normal operating position and it is desired to usethe machine the door 40 is first slid upwards into its open position wherein it exposes the opening 39 in the front upper portion of the side wall 30 of the outer shell. Thereafter the inner shell I! is rotated by proper control of the power mechanism I8 into a position wherein the opening 50 in the side wall 45 thereof is in registry with the opening 30 in the side Wall of the outer shell. Thereupon the door 5| for the opening 50 is slid into its open position and the interior of the inner shell is charged with clothes and other articles to be washed via the openings 39 and 50. After charging of the inner shell the doors 5! and 40 are closed and water is introduced into the outer shell by way of the fitting III and the pipe section II8. After filling the outer shell to the desired height the power mechanism I8 is set in motion by supplying current to the three phase reversible motor 53. During operation of the motor the inner shell II' within'the outer shell rotates back and forth for clothes washing purposes. After the clothes have been washed the power mechanism III is stopped and the dump valve 38 is opened so as to discharge thewater from they interior of the inner shell. Thereafter the door 40 is opened and the inner shell is rotated until its opening 50 is in registry with the opening 33 in the side wall of the outer shell. Upon eiiecting registration of .the openings 50 and 39 the door 5I is opened and effecting, through the medium of the piston rods I2, upward and forward swinging of the outer shell I6 into its discharging position. As soon as the outer shell reaches such position the clothes are automatically discharged by gravity through the openings 50 and 39. .After the discharging operation the lever I00 is swung to its fullest extent in a clockwise direction as viewed in Fi ures 7 and 10 in order to cause the oil under pressure to be introduced into the upper ends of the cylinders 04 and the pistons65 resultantly to slide downwards and effect return of the outer'shell to its normal operating position. As soon as the outer shell is swung intoits normal operating position wherein it is supported by the pins 43 and the hooks 44 the operator of the machine swings the lower I00 into its neutral or vertical position so as to discontinue drive of the gear pump I6.

The herein-described washing machine effectively and efllciently fulfills its intended purpose and may be operated with great facility and speed. It is automatic so far as discharge of the washed clothes and other articles is concerned 11 and ischaracterized by the fact that the power mechanism ID for operating the inner shell is entirely "mounted on the outer shell and hence is always in operative or driving relation with the inner shell regardless of whether the outer. shell is in its normal operating positlon'or its discharging position.
