ATo all whom it may concern:

Be it known that I, DANA H. BENJAMIN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have' invented certain new,

and useful Improvements in Gearing for Washing-Machines, of which thefollowing is a specification..

This invention relates generally to methem successively .into and out of engage-v ment with the receptacle -driven member.

The invention may be further brieily summarized as consisting in the construction and combination of parts hereinafter set forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is a side elevatlon of the device applied with parts broken away; Fig.4 1a is a detail sec-l -tion of the wedge adjustment for the cam.;

Fig. 2 is an end view with one gear case in sect1on;.F1g. 3 1s a sectional view taken on the line corresponding to a vertical plane cutting the axis of the driven member and back of the oppositely driven friction wheels; Fig. 4 is a horizontal section taken on a line cutting the axis of the driven member; and Fig. 5 isa vertical sectional view of the driving mechanism; Fig. 6 is ato plan view of the trough and cylinder; an Fig. 7 is a cross section of these parts.

' In carrying out the invention any preferred form and construction of parts may be employed so long as it possesses the neces-- sary characteristics, but I have shown one arrangement which is effective, and in s uch embodiment 1 represents asuitable framework provided with a trough-shaped rece -Y tacle 2 having suitable heads 3 and 4, t e former being provided with a bearing consisting of a fianged sleeve 5 extending through the head and having threaded to the inner end a flange 6 adapted to be ses cured to the inner face of the head. The

opposite head 4 is provided with a bushing 7 adapted to receive a pin 8 arranged in the bushing and having a reduced trunnion portion 9. This pin 8 is held in place by a lock pin 10 passing through proJe'cting portion of the sleeve 7 and through the pin 8.

. Mounted in the bearing sleeve 5 is an agitator driven shaft or member 11 having on the outside of the head 3 a main driving member 12 provided at its periphery with a ange 13. This flange is provided internally with an annular V-shaped groove 14 for a purpose to be described.A This driven member is also provided with a suitable pilot or shaft extension 15, as shown in Fi 4. The inner end of the driven shaft 11 1s provided with a squared portion 16 entering a correspondingly shaped opening in the socket member 17 secured in the head 18 of i a cylindrical agitator 19, the other head 20 of this agitator being provided with a suit- Aable bearmg-member 21 adapted to receive and adapted to e closed by a door or plate 24 having cleats 25 on the bottom thereof. These cleats have extensions 26 extending under the wall at one ed e. About the opposite ed the outsi e wall'of the cylinder to hold the door in place at this point. The inner wall of the cylinder is also rovided with longitudinally disposed ba e plates 27 spaced around the inner wall. Y

The mechanism for driving the driven l' shaft or member is mounted ina casing 28 having diametrically disposed-bearings 29 and 30 which receive a diagonally disposed a suitable latc 27 is provided on operating shaft 31 which is further mounted 1n bearings 32 and 33 secured to the head 3. This shaft has on its lower end a gear 34 driven by a pinion 35 operated by a motor. The upper end of the shaft is provided with a bevel pinion 36 meshin wltha gear 37 secured to a verticallydisposed shaft 38, shown in dotted lines in Fig. 1, and having upon the upper end a bevel inion 39, engaging a bevel gear 40 moun u on a shaft supported in a bearing 41 and a on the opposite side of this bearinga, cutch member 42. This clutch member is adapted to be engaged by av wringer clutch member 43 slidably mounted upon a wringer i 44. This shaft is provided with a wringer 'mounted upon the shaft 49.

roll 45 engaging with another wringer roll 46, both of which are supported in a suitable framework 47.

The driving mechanism will now be described. Forming part of the front of 'the casing 28 is a bearing 48 having mounted therein a shaft 49 extending into the casing 28 and to a point within the flange 13 of the driven shaft or member 12. This shaft has loosely splined to it, just inside of the front of the case, a clutch member 51 having a groove ada ted to receive the ends of a forked shifting lever 52 pivoted to a suitable bracket 53 formin a part of the case. The handle 54 of this ever projects' up through a suitable opening in the casing. This clutch member coperates with a clutch member 55 integral with'a worm gear 56 loosely This worm gear meshes with a worm 57 secured to the shaft 31. Secured to the shaft 49, just inside of `the worm gear 56,- is a main driving gear 58 for a purpose-to be described. The shaft 49 is continued loosely through a swinging frame 59 vand through the end of a link 60 which has a bearing portion 61 at its lower'end adapted tengage the pilot shaft portion 15 of the driven shaft' 0r member. In this way the shaft 49 is supportedfatA both ends with respect to the axis of the driven shaft or member. The swinging orj pivoted frame 59 is provided with a bearing 62 for a direct drive friction wheel shaft 63, a bearing 64 for a reverse friction wheel vdrive shaft 65, and a back gear shaft supporting boss 66 carrying a back gear shaft 67. This frame is also provided with an outwardly extending bracket 68 shown in Fig. 1 and having on the outer end a pair of bearing boxes 69 which support a worm shaft 70 upon which is mounted a worm wheel 71 adapted to be driven by mechanism to be described. The outer end of the shaft 70 is provided with a cam 72 adapted for engagement with a suitable stop preferably comprising a wedge 73 mounted in a bracket 74 secured to the head 3. This wedge is held in any adjusted position by -beyond this same shaft is provided with a worm 78 meshing with the worm wheel 71. The shaft 65 is provided with a spur gear 79 meshin with a back gear 80 mounted upon the gear 80 in turn meshes with the main driving gear 58. 0n the inside of the swinging or pivoted frame 59 this shaft 65 is provided ack gear shaft 67. 'This back with a friction wheel S1 similar in all respects to the friction wheel 76 except that it has the opposite direction of rotation. 1n order to vcause the cam 72 to normally remain in engagement with the wedge 73a spring 82 is arranged between an ear 83 4on the bracket 68 and a fixed bracket 84 secured to the main frame. In this waythe entire swinging frame has a tendency to swing in a clockwise direction on its center, thus maintaining the engagement between the' cam and the wedge.'

In operation the door of the cylinder is `opened and the articles to be washed are 1nserted and the door closed, suitable washing solution having been previously placed in the trough or tub. The clutch member 51 is thrown in the proper direction to cause the driving of the main driving gear 58 with the result that the two friction wheels 76 and 81 are driven, and in like manner the cam 72 is driven, causing,the swinging frame to bring one or the other of the friction wheels into engagement with the driven shaft or member of the receptacle.

This causes the receptacle cylinder to bel 2. A mechanical movement, comprising adriven member, a movable supporting frame,
