To llfwhomt mag/concern."

Be 1t known that I, WILLIAM H. GEORGE, a citizen ofthe United States, and a resident of Fairfield, in the county of Jefferson and; State of Iowa, haveinvented Ncer-tain new and useful Improvements `in Gearing; and I .do hereby declare that the following is a full, clear, and exact description thereof,

reference being had -to the accompanying drawings, and to the ,letters'of reference marked thereon, whichform a part of this 'specication ed out in the appended claims.

The object of the lnvention 1s to provide a simple and eiiicient gearing more particularlyadapted for embodiment in a Washing machine, for imparting a rocking or oscillating movement to the water Vand clothesreceiving container thereof for the purpose of' washing/the clothes.

The advantages of the invention will be more fully set forth as I proceed with my specification. l

y Fig. 2 illustrates a horizontal, sectional View through the washing machine, 'inY a plane indicated by the line 2-2 of Fig. 1. l

Fig. 3 illustrates, on an enlarged scale, al faceview of the gear casing with the frontr cover plate removed.

Fig. 4 illustrates l af horizontal section through the gear casing, in a plane indicated by the line 4-4 of Fig. 3. Y

Fig. 5 illustrates a vertical section through the gear casing, in a plane-indicated by the line 5.-'5 of Figi.. 3. Y

Referring now in detail to that embodiment of the invention illustrated in the ac;

companying drawings, 10-10 indicatesthe side frame'members, each of which consists of 'an invertedU-shaped member made of channel iron. Each frame member includes a horizontal vtop rail 11, and, upright bars 12, that provide the legs for the washing Specification of Letters Patent. Patented June Application filed February 5, 1920. Serial No. 356,558.

L15 respectively, there being an intermediate bar 16, connecting the angle bars 13 vtogether .between their ends. The construction f just described provides a light, rigid frame or support upon which the rest of the mechanism. is mounted.

At the middle of each top' rail 11, is secured a bearing block 17, in which is jour# naled the trunnions 18 of rocking. or oscillating clothes receiver 19, which is adapted to rock about said trunnions as 'an axis, in a path parallel to the side frame members 10. As shown, said clothes receiver has horizontal top and bottom walls 20" and 21, and

semi-cylindric end walls 22 and flat upright side walls 23, to which are secured brackets or spiders 24 that carry the trunnions 18 before referred to. In the top wall of the clothes receiver 19, is a door 25, through which the clothes to 'be washed are placed within, and removed from said receiver. One of the spiders 24'is provided with a stud 26 which is -spaced from the trunnion".

18, the purpose of which will presently apear.

30 indicates a gear casing which includes a removable, upright cover plate 31. This cover plate has a hollow boss 32 which rests upon and .is secured to one of the angle bars 13 of the frame, by `means 'of bolts passing through ears .33' made integral with said hollow boss. Journaled at one end-in said gear' casing is a horizontal shaft 34, the opposite end of which is journaled in a bearing block 35, secured to another brace 36 (see Fig. 2)-

that connects the rear end and

intermediate frame bars

15 and 16 respectively together. Fixedr to this end of the shaft 34, outside of the bar 36,.is.a crank, arm 37 which is connected by a pitman or link 38 to the vstud 26 on the clothes receiver 19. Thus, as

vis apparent when thel shaft 34 is rotating, a

rocking or oscillating movement is imparted to the clothes receiver through the crank arm 37, link 38 `and stud 26 respectively.-

Fixed to that` end of the shaft 34, within the gear casing is a clutch member 40 (see Fig. 5) and loosely mounted on said end of i said shaft and capable of alongitudinal movement thereon, toward and away from the clutch 'inember 40,` is a spur pinion' 41. This pinion includes a clutch member 42,

which is adapted to be engaged with and disengaged from the clutch member 40, before referred to. rIhe pinion 41 is also provided s u 47, .meshes with a pinion 48 fixed to a horizontal shaft 49, journaled in saidgear case. To that end of the shaft 49, without the gear case is Vfixed a grooved pulley 50, driven by a belt 51 from a smaller pulley 52 on the armature s aft of an electric motor 53. Preferably, I hang said `motor from the underside of a board or like support 54, which is secured at one end to the frame bar 14, and is secured at its other end to a hanger' 55, depending from the intermediate bar 16 of the frame.

In the hollow boss 32, of the cover plate l31, is journaled the bottom end of an upright shaft'60, and fixed to said shaft within `said boss isa bevel pinion 61 that meshes with the bevel pinion 47 formed integral with the large spur gear 45. The top end of this shaft is journaled in a bearing 62, on a Shelf or board 63,` located in a plane above the top of the clothes receiver 19, said shelf being secured to suitably bent bars 64 rising from and secured as shown to each side member l0 of the frame. The top` end of the shaft is squared to engage in the gear box of a clothes wringer (not shown) which is adapted to be swung into different positions about the said shaft as an axis.

Associated with the Vlongitudinally shiftable gear pinion 41 on the shaft 34, is 'a clutch shifting member 70, the forked bottom end of which engages in the4 groove 43, provided therefor in said gear pinion.,` The top end of said shifter which extends upwardly through a slot 71 in the top wall of the gear casing has a horizontal stem 73 which extends through a hole 74 in van ear 75 of the cover plate, thereV being a spring 72, surrounding said stem between said ear and the top end of said shifter member 70,

which acts normally to engage the clutch member 42 withthe clutch member 40 on the shaft 34.

0n the outer,free end of the stem 73, is a plate 76 which is adapted to be engaged by the horizontally bent end 77 of an upright control rod 78 which is j ournaled at its top and bottom ends in the ear 75 of the cover plate and a bearing bracket 79 on the to member of the adjacent side frame l0. T e top end of said control rod is bent as at 8 0 to provide` a handle by means of which the control rod is. actuated.

Theoperation of the improved gearing as above described, is as follows: Assume that the motor' 53 isv running to drive'the pulley andishaft'O and 49 respectively. This will through the gear 45 drive continuously the upright shaft and the gear 41 which is loose on the shaft 34. VVhenit is desired to drive the shaft 34 to impart arocking or oscillating movement to the clothes container 19, the handle ,80 of the control rod-is actuated to move the bent lower end 77 away from the plate 76 on the stem 73 of the clutch shifter 'when the spring 72 will act to move the shifter `7 0 to the right as shown in Fig. 5, to cause an engagement between the clutch members 40 and 42 respectively. When the clutch members are thus engaged, the gear pinion 41 which `is meshing with the pinion 44 of the vgear 45, Will impart a driving connection to the shaft to thus rock tlie'clothes receiver as before described.

To stop the movement of the clothes receiver, the operator actuates the rod 78, so that its bent, lower end 77 ,will engage the plate 76 and move the same outwardly, together with the clutch shifter 7 0 which will move the clutch member 42 and gear 41 endwise on the shaft 34 when the engagement between said clutch members is broken.

Thus by a simple movement by the operator, the actuation of the clothes receiver is readil controlled. The gearing described provi es for the proper gear speed reduction between the motor and the clothesy receiver and said gearing may all be assembled in said casing before the casing is attached in place. All the gearing is fully inclosed.
