GEARING.

Application filed April 19, 1919. Serial No. 291,182.

To all whomit may concern.

Be it known that I, JAMES V. E. ERICK- soN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certam new and useful Improvements in Gearing; and I do hereby declare that the following is a full, clearpand exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. I

This invention relates to improvements in gearing and" consists of the matters hereinafter described and more particularly pointed out in-the appended claims.

The improved gearing is of especial advantage for use in connection with washing ,machines of the oscillating cylinder type,

such as is shown in the patent to Gustav B. Keil, No. 1,245,109, of October 30, 1917, and it is herein illustrated and described as applied to such a machine, but as is apparent,

the improved gearing may be used in other types of washing machines where its peculiar characteristics make it advantageous to do so.

The advantages of the improved gearing will be more apparent as I proceed with my specification. I

In the drawings:

Fig. 1 is a view representing a front end elevation of an oscillating cylinder washing machine to which the improved gearing has been applied.

Fig. 2 is a view representing a longitudinal, vertical section through the same, the

plane of the section being indicated by the line 22 of Figure 1. Fig. 3 is a new representing a transverse, horizontal section through one end of.

the washing machine, the plane of the sec tion being indicated by the line 33 of fi ig. 4 is a view in elevation andon' an enlarged scale, of the improved gearing, shown as removed from the rest of' the mechanism of the washing machine.

Fig. 5 is a detail sectional view on an enlarged scale, through a part of the gearing shown in the right hand end of Figure 2.

Fig. 6 is a detail, horizontal, sectional view on an enlarged. scale, through another part of the gearing, the plane of the sec- ;ion .loeing indicated by the line 66 of 1 fi-eferring now in detail to that embodi- Speciflcation of Letters Patent. Patented F b. 1, 1922 i ment of the invention illustrated in the accompanying drawings :10 indicates a main support for the gearing which, as illustrated, 1s the tub of a washing machine of the oscillating cylinder type. Said .tub is mounted at its corners upon front and rear pairs of uprightlegs 11' and 12 respectively. Said legs are made of angle bars, so arranged that the angles thereof define the corners of the support. The front pair of legs 11 are connected together at their top ends by an angle bar 13 and all the legs 11 and. 12 are connected together near their bottom ends by the channel irons-14, which act to rigidly brace the legs.

, The tub10 is inade of sheet metal and includes a transversely rounded bottom wall 10 which blends into upright side walls,

and upright front and rear end walls 10,

10, respectively, said front wall being spaced 'rea-rwardly from the front legs 11.

v A cover'15 is hinged to the topedge of said rear wall. A horizontal plate 16 which is interposed between the angle bar 13 and the.

front wall 10", forms a top closure for the space between said front legs and front wall. A second ilate 17 is-fixed to the front face of the ang e bar 13 and to the bottom edge of saidplate is hinged an apron 18 which has a spring catch at its bottomedge, to engage and lock with the channel iron 14 that connects the front legs 11 together.

Within the tub 10 is mounted a cylinder 19 which is adapted for an oscillating movement in said tub. Said cylinder is of the usual structure for. washing machines and includes a lid 20 which may be removed for the purpose of placing. the clothin to be washed in the cylinder. Fixedto t e rear upright wall of said cylinder in a plane above its center of gravity, is a. trunnion 21 which is removably journaled in an upwardly opening groove of a yoke 22 fixed to therear wall 10 of the tub 10. To the front wall of the cylinder is fixed a bearing plate 23 which is capable of a detachable operative engagement with theinner end of a horizontal, power-driven, rotary, oscillating stub shaft. 24, which projects through the front wall 10 of the tub, in axial'alignment with the trunnion 21. When the shaft 24 is at rest, the cylinder 19 may be removed from the tab 10, by lifting it from engagement with the shaft 24 and bracket 22, the lid of the tub, of course, being first opened to persuch removal.

The front wall 10 of the tub, together with the plate 16, and apron 18, defines a compartment 25 locatedlwi'thin the plane of the front legs 11. in said compartment is located the power driven gearing which imparts the oscillating movement to the cylinat the left hand end of the body, are fixed to the other oi said front legs. Between its ends, and at the top of the bracket 26, is prov ded an over-hanging, forwardly exam a 31, which terminates in a dcpending flange 32, so arranged as to receive and provide bearing for the outer end of the stub shalt 2d, the inner end of which extends through and has bearing in a boss 33 termed on the body of said bracket.

34 indicates a forwardly extending, horirental stub shaft fined in the body 27 of the bracket 28 in a plane parallel with the opera shaft 24;, and on this shaft is ro- ,tatively mounted a spur gear 35. The teeth oil said gear mesh with the teeth of aworm gwr 3d fixedto a; horizontally disposed shaft 37 ed at an angle to the plane of nr gear. Said shalt has bearing near its ends insleeves 38, 39, made integral witha r 'w platev d0 bolted to the bracket body 2'2,

lw the gear 34. This shaft 37 is connected by'a coup w 1' 41 to the armaand, wanna with the eat of the shaft 42 of an electric motor 43 which is r a ded in an inverted position from a plate or d lhthat extends torwardl from the, body 2? of the bracket 26, in a in substantially, vertically below the overeion" 31 before referred to.

Thmtor 3 is adjustable with reference to the flange 44 so that its armature'shait may. be m with reference to the worm shalt 3'8. In the boa sleeve38is nnnntifriction bea 38 to take up the end of said-shaft 37. (See ]Fig. 6.) e -l g plate includes an oil cup 45 in which islocatedfa spur gear 46, loosely mounted on a stud 4L7. This r preternlily is inarle with teeth of felt or e niaworin 3d and-act as a wiper on said worm to hrorfdhtthe throwing or lg of 6 lubricating oil maintained in said cup for the purpose of lubricating the worm gear.

'AS the worm gear is driven at a one to one meshes with and actuates a segmental gear 49 fixed to a clutch sleeve 50 loosely mounted on the reduced outer end part 24? of the shaft 24. This clutch, sleeve (see Fig. 5) is held against .endwise movement on said shaft, by reason of its engagement between the bearing flange 32 and a shoulder 24 formed at the junction between said reduced outer part 24 and the inner end part 24: of greater diameter, of said shaft. Between its ends, one side of the clutch sleeve 50 is flattened or broached to fit ina similarly shaped hole in the segmental gear 49, and a set screw 49 rigidly secures said gear on said sleeve.

The rack bar 48 is held in engagement with the segmental gear 49 by a. swinging basket 53 which has a bearingsleevc 54: in

vwhich the rack has sliding bearing, and by spaced front and rear'apertured arms 55 that embrace and have pivotal bearing on the ends of the clutch sleeve 50, on either side of the hub of the gear 49. The inner end part 24 of the shaft 24:, is broached on one side as at 24, and on said inner end part is slidabl and non-rotatively mounted a clutch co ar 56 which may be shifted endwise on said shaft, into and out of engagement with the adjacent end of the associated clutch sleeve 50. In said clutch collar is an annular groove 57 adapted to receive the end of a clutch shifting lever 58 (see. Fig. 1) mounted on the inner end of a rock shaft 59. This rock shaft is iournaled in suitable bearing lugs on the bracket 26 and has its outer end extended beyond the left hand side wall of the machine, where it isprovided with an operating lever 60. v

The operation of the parts thus far described, 18 as follows:

When the motor is rug, it will drive the rack bar 48 which will oscillate the segmental gear 49 and clutch sleeve 50- to 80 will produce an :i lement or disengaent between the clutch collar- '56 and the clutch sleeve 50, so that when said which it is attached. Actuation of the lever collar and sleeve are enged, an oscillat ing movement is imparted to the shaft 24% which in turn will impart a like movement to the cylinder 19. \Vhen the clutch collar and sleeve are disengaged, and the motor is running, the segmental gear and clutch sleeve will oscillate on the shaft 24 withoutimparting any movement to it.

The gearing for driving the wringer mechanism is as follows:

:Rotatively mounted on a stud on the bracket 26, in a plane above the gear 35, is a combined spur and bevel gear 61, the spur gear part of which meshes with the gear.

35. The bevel gear part of said combined gear meshes with oppositely facing.

gears 62, 62, loosely mounted on a horizontal shaft 63 journaled in the bracket 26.

The opposed faces of said bevel gears have clutch members which are adapted to be engaged by a clutch collar 64, keyed to slide on said shaft between said gears. Said collar 64 is actuated by a bell crank lever 65 pivoted on a stud 66 on the bracket 26, above the combined gear 61. The horizontal arm of said lever 65 projects beyond the adjacent side of the machine where it is connected by a link to a shifting lever 67 pivoted on a stud carried by abracket 68, rigidly secured to i the machine above the adjacent front leg 11.

To the outer end of the shaft 63 is fixed a sprocket 70 which, through a chain 71, drives the shaft 72 of a clothes wringer 73, rigidly secured to the angle bar 13. It is apparent thatby shifting the lever 67, the wringer may be driven in either direction or may be stopped, even though the gear 35 is being driven to oscillate the segmental gear 49.

. The improved gearing has many advantages. By setting the shaft 37 at an angle, a worm geardrive to the spur gear 35 may be provided, and plenty of room may be had in the compartment 25 for the driving motected against breakage, or damage from such wash Water as may be spilled, during the washing operation. All of'the gearing may be assembled on the bracket 26 beforesaid bracket is secured in place Within said compartment. By the reduction of the number of parts used, frictlon and noise are re duced to a minimum. The use of the Wiper gear 47 prevents the splashing and throwing of oil, due to the high speed at which the mechanism is driven.

I claim as my invention:

A gearing device of the kind described comprising, a support including a bracket plate, a horizontal operating shaft journalled in the bracket plate, there being a horizontal outstanding flange on the bracket plate below the operating shaft and afsecond shaft below and to one side of said operating shaft, a-spur gear on said second shaft, means operatively connecting the spur gear'with the operating shaft for imparting an oscillatory movement'thereto, a

horizontally disposed worm journalled insaid worm extending in a plane at an acute angle to that of said spur gear, and a motor depending from said bracket flange and directly connected to said Worm.

In testimony, that I claim the foregoing as my invention, I aiiix my signature in the presence of two witnesses, this 15th day of April, A. D., 1919.
