OSGILLA'I'ING MECHANISM FOR WASHING MACHINES.

Application filed December 17, 1923. Serial No. 681,277.

To all whom it may concem:

Be it known thatI, EDWARD F. VANnpI-r- BOSCH, a citizen of the United States, residing at Laporte, in the county of La Porte and State of Indiana, have invented certain new and useful Improvements in Oscillating Mechanism for Washing Machines, of which the following is a specification.

The invention relates to oscillating mech anism for washing machines, and has for its object to provide a device of this character' wherein a pivoted washing machine receptacle will be operated in a manner whereby jerking or hammering of the parts at the time of reversal of movement of the receptacle will be obviated.

A further object is to provide oscillating mechanism for washing machine receptacles, which mechanism comprises a slidable crosshead mounted in guides of one end of the receptacle, and provided with an internal gear driven by drive pinions at a fixed point for reciprocating the cross head in the guides and imparting an oscillatory movement to the receptacle. Also to provide an idle gear carried by the cross head and with which idle gear the drive pinion meshes" for holding the drive pinion in mesh with the internal gear during the reciprocation of the cross head by the drive pinion. The

idle gear also acts as a thrust bearing for the drive pinion.

A further object is to slidably mount the cross head radially to the axis of the receptacle, thereby insuring oscillations of equal length to either side of the axis of the receptacle.

A further object is to provide a motor for driving the drive pinion through the medium of a worm and worm gear carried by the frame of the washing machine adjacent the crosshead, thereby providing a compact structure.

A further object is to provide an oscillating mechanism for a washing machine receptacle wherein the pivoted receptacle is oscillated through the reci rocation of a radially movable crosshea mounted in guides. I

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a perspective view of a washing machine, showing the device applied thereto.

Figure 2 is a front elevation of one end of the washing machine receptacle, showing the oscillating mechanism applied thereto.

Figure 3 is an enlarged side elevation of one end of the washing machine receptacle. showing the oscillating mechanism applied thereto.

Figure 4 is a horizontal sectional view through one end of the receptacle, taken on line 44 of Figure 3.

Referring to the drawing, the numeral 1 designates the frame of the washing machine and 2 the receptacle thereof, in which receptacle, articles of clothing are placed during a washing operation. In washing machines of the oscillating type, as at present constructed, when the direction of oscillation is reversed, a jerking or hammerin of the parts takes place incident to the sudden reversal. To obviate this difficult; the receptacle 2 is oscillated on its pintles 3 by means of a crosshead 4, which crosshead is slidably mounted in crosshead guides 5 disposed within a casing 6 secured by means of rivets 7 to one end of the receptacle 2. The crosshead 4 is'radially movable in relation to the pintles 3 of the receptacle, thereby insuring the same length of oscillatory strokes to each side of the vertical longitudinal center of the receptacle 2, consequently a uniform agitation will take'place within the receptacle 2 during the operation of the device. Grosshead 4 is provided with an internal gear 8, with which gear a fixed drive pinion 9 meshes, which pinion is carried by a horizontally, disposed shaft. 10, which is rotatably mounted in a bearing 11 of the outwardly extending portion 12 of a gear casing 13. Disposed on the upper end of the gear casing 13 is a conventional form of motor 14, preferably an electric motor, which motor has its drive shaft 15 vertically disposed and provided with a worm 16, which meshes with a worm gear 17, therefore it will be seen that the drive pinion 9 is driven by the motor 14, and said drive pinion will be constantly rotated in one direction by the motor during the operation of the motor, but will remain at a fixed point, as the same is supported by the portion 12oftheicasing 13 of the frame 1. During the rotation of the drive pinion 9, the crosshead 4 is moved towards I ,the axis of the receptacle 2, and at the same internal gear as the drivepinion 9 moves time gradually moved to one side of thelongitudlnal vertical center of the receptacle, thereby swinging the receptacle on its pintles 3 to the dotted line .position shown in Figure 3, at which time the .drive pinion 9 assumes a dead center position gradually, consequently jerking or hammering of the parts is obviated, as there is'momentarily no sliding movement of the crosshead 4 when it assumes the dead center position as shown in dotted lines in Figure 3. However as the pinion 9 continues to rotate and which spider is provided with a stub shaft,

18, axially disposed in relation to the internal gear 8, and on which stub shaft is rotatably'mounted an idle gear 19. v The idle gear 19 moves with the crosshead 4, and meshes with the drive pinion 9, consequently not only ,acts as a thrust bearing for the rive inion 9, but at the same. time maintains t e drive pinion 9 in mesh with the around the internal gear 8, thereby insuring a positive operation of the device and the reciprocation and oscillation of the crossheagl9 4 during the rotation of the drive pinion From the above it will be seen that adriving mechanism is provided for oscillating washing machine receptacles wherein the structure is compact, and the receptacle oscillated by the reciprocation of a crosshead in guides, which crosshead is simultaneously oscillated. It will also be seen that the crosshead is driven by a drive pinion dis-- posed at a fixed point, and meshing with an internal gear carried by the crosshead, thereby getting a maximum oscillation in a minimum amount of movement of the crosshead.

The pintle 13 of the receptacle 2, which is 4 disposed adjacent the driving mechanism may be mounted in any manner desired,

however it is preferably carried by a bar 20,

which connects the outer sides of the guides 1 5, thereby allowing the crosshead 4 to move between the pintle 3 and the adjacent end of the rece tacle2 behind the bar 20, therefore 1t will e seen that the crossheadwill. not

come into engagement with the pintle 3 in its upward movement, and the driving mechanism may be placed relatively close to the axis of the receptacle 2. 4

The invention having been set forth what is claimed as new and useful is 1. The combination with a pivoted recep tacle, of means for oscillating said receptacle, said means comprising a crosshead, guides for said crosshead carried bythe receptacle, means for simultaneously reciprocating and. oscillating the crosshead comprising a gear carried by the crosshead, a

drive pinion meshing with the crosshead gear, and means for rotatingthe. drive pin- 1011.

guides tor said crosshead carried by the receptacle, means for simultaneously reciprocating and oscillating the crosshead, said means comprising a gear carried by the crosshead, a fixed rotatable gear meshing with the crosshead. gear. and means for'rotating the fixed rotatable gear.

3. The combination with a pivoted receptacle, of means for oscillating said receptacle. said means comprising a movable' crosshead, guides carried by the receptacle in which said crosshead is slidably mounted, an internal gear carried by the crosshead, a

" fixed drive pinion meshing with the internal gear, means cooperating with the drive pinion for maintaining the same in mesh with the internal gear, and means .for rotating the drive pinion.
