To (ZZZ whom it mag/concern Bait khownthatl', GUsrA-vn Wen-stimulus, a citizen of the UnitedSt-ates, and residing at Galesburg, in the county of Knox and State of lllinois, have invented a new and useful Improvement in Wringer Attachmeets for l Vashihgdiiachines, of which the following is a complete specification.

The main objects oithis invention are to provide improved mechanism for mounting wringers on washing machines; to provide mechanism whereby the Wringer is adapted to be supported in one position to wring from the washing machine to a tub, and in another position to wring trom the-first tub to a second tub or vice verse; to provide mechanism adapted to swing the wringer through a vertical arcfrom one position to another; to provide mechanism for operating the wringer in any of its-adjusted positions; to provide improved means for re versing the wringer; and toprovide a strong and simple device by means of which the wringer may be quickly and easily moved from the washing" machine to the tubs and vice versa.

A specific embodiment of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a washing machine with the means for mounting and.

operating the w 'inger embodie in this in vention attached thereto. Fig. 2 is a side elevation of the gear bracket or frame. d ig. 8 is an end elevation of the gear bracket or frame. Fig. 4 is a top plan view (if-the washing machine and its attachments, with the platform removed. Fig. is a tragn'lcntary section talien'on line 55 of Fig. i. Fig. 6 is a fragmentary view of the reversing mechanism for the wring'er. Fig. 7 is a front elevation of the same.

In the construction shown the washing machine bench or frame comprises front legs or posts 1 and legs or posts 2, which are secured together by longitudinal rails or side members 3 and end members 4:. vOn the'side members P is a platform 5 on which the washing machine 6 and tub 7 are supported. A tub 8 is suitably supported the front end of the frame.

The wringer 9 is so mounted that it is adapted to be swung through a vertical are from its forward position and oppositely. For this purpose a pair of vertical swin ing arms. 10 and 11 adapted to swing in garutllolism are pivoted at each side of the rame and support the wringer. (lne of the arms 10 is pivoted at its lower end on. the outer end of the clutch shaft 12 and the other arm 10 is pivoted on a stud pin 13 at the'other side of the frame and in alinement with pivoted at their lower ends on stud pins 141- carried on the frame members 3 forwardly of'the arms 10. The upper ends of the arms 10 and ll-of each pair are connected by a horizontal supporting bar 15 whichis pivot ed to said arms and holds their upper ends the some distance apart as their lower ends.

The wringer base 16 is rigidly secured at its ends on said bars 15, and in the forward position of said arms is adapted to rest on the tops of the posts 1., and in the rearward position of said arms is adapted to rest on a ledge 17 on the washing machine, as is shown more clearly in full and dotted lines respectively in Fig. 1.

A gear bracket or frame 18 is rigidly secured on the inner side of one of the side frame members 3, and the clutch shaft 12 is journaled at its inner end in a bearing 19 in said bracket and at its outer end in a suitable bearing 20 on the under side ofsaid'irame member 3.

Loosely mounted on the shaft 12 are the gears 21 and 22, which have clutch members 23 and 2% respectively on their adjacent faces. Slidably mounted on the shaft 12,

intermediate the gears 21 and 22, is the clutch member 25 adapted to lock either .of said gears to the shaft. On the outer end of the shaft 12 is a sprocket wheel 26 in alinement with a larger sprocket wheel 27 on the \vringer shaft 28, and a sprocket chain 29 is carried on said sprocket wheels and acts to drive the wringer in either direction from the shaft 12.

A shaft 30 is journaled in bearings 31 and 32 respectively on the bracket l8 and the frame member 3, intermediate the shaft 12 and the washing machine. Gears 33 and 34 are rigidly secured on the shaft 30 in alinement with the gears 21 and 22. The gear 33 is out of mesh with the gear 21 and the gear 31 is in mesh with the gear 22. A drive pulley 35 is carried on a stud shaft 36 which is journaled in a bearin 37 in the bracket 18, and on the inner end of said stud shaft is a pinion 38 which meshes with the gears 21 and 33. On the outer end of the shaft 30 is a pinthe shaft 12. Both of the arms ill are ion 39 which meshes with a pitman gear 40 ournaled on the frame member 3. A rock shaft 11 is journaled at the rear of the frame and is provided at oneend with an 5 arm or lever 42 which is connected with the pitinan gear by means of a bar 43. An arm 44 is rigidly secured on the other end of the shaft il and is connected at its upper end to the operating mechanism of the 10 washing machine by means of a connecting link 46.

F or the purpose of controlling the direction in which the wringer is operated, shafts 4'? and 18 are journaled in the lower ends of 15 the posts 1 and 2 respectively, and are provided on their ends, at the outer sides of said posts with treadles 19. Each shaft 4:7 and 48 is provided with an upwardly directed lever 50, whichlevers are connected 20 together by a bar 'or rod 51. Rigidly secured on and extending up\vardly 'from the bar 51 is a bar 52 which is pivotally connected at its other end to one arm of a bellcrank lever 53. The bell-crank lever is piv- 2 oted to the bracket 18, and its other arm is provided with a fork 54; in engagement with the clutch member and adapted to shift the same. I The operation of the construction shown 3 is as follows: The shaft 36 is driven from any suitable source of power and operates the washer mechanism through the intermediary of the gears 38, 33, 39 and 10 and the connections with the rock shaft 41. If 5 it is desired that the washer shall remain idle while the shaft 36 is in operation, the link 16 is disconnected from the washing mechanism 45. If the drive pulley is rotated in the direction indicated by the arrow in Fig. 1, and the clutch member 25 is thrown into engagement with the clutch member 2 the gear 21 is locked to the shaft 12 and the wringer is operated in a direction to run the clothes from the rinsing tub 7 is to the bluing tub if the wringer is in the position shown in fulllines in Fig. 1, or to run the clothes from the washer-6 to the rinsing tub T, if the wringer is in the position shown in dotted lines in Fig. 1. When it ao'is desired to run the clothes from the tub .8 the clutch member is shifted into engagement with the clutch member 2%, thereby locking the gear 22 to the shaft 19., which shaft is then driven in the opposite direc- 55 tion through the gears 33 and 31, thereby reversing-the operation of the wringer. A tray may be placed on the tub 7 to catch the clothes, or said Luh may be replaced by a basket.

It will be readily understood that when the wringer is wringing from the tub 7 to the tub 8, or from the tub 8 the washer may be in operation if desired.

It will also be readily understood that the \vringer may be easily and quickly changed from the position shown in full lines in Fig. 1, to that shown in dotted lines by simply swinging the arms 10 and 11 through a vertical arc, thereby practically eliminating all friction in moving the wringer, and" without in any way disturbing the operating mec anism. The wringer, because of said pairs of arms swinging in parallelism always assumes a horizontal position regardless of the position of said arms, and is always rigidly supported when in. operative position.

Obviously many details of the construction shown and described may be varied or omitted without departing from the scope of the claims.

I claim:

1. In combination with a frame which includes side frame-rails, a shaft supported transversely of one of said rails, a sprocket wheel on said shaft, swinging arms, 10, one of them pivoted on said shaft, the other being pivoted on a stud-pin in line with said shaft, stud-pins supported transversely of said rails, swinging arms, 11, pivoted on said stud-pins, a horizontal arm pivoted to the upper ends of each couple 10, 11, of said swinging arms, a support carried on said horizontal arms, a. shaft supported thereby, a sprocket wheel on said shaft, and a chain embracing said wheel and the one first recited.
