GEARING.

Specification of Letters Patent.

Patented Feb. is, rare.

Application filed. ()ctober 21,1911. Serial No. 'e55, s52.

To all whom it may concern Be it known that I, JOHN EDENS, a citizen of the United States,- and a resident of l Davenport, in the county of Scott and State -of Iowa, have invented certain new and useful Improvements 1n Gear ng; and I do hereby declare that the following is av full,

- clear, and exact description thereof, refertion.

after described and more particularly point-- ed out in the appended claims. Y

The invention as shown herein is applie to a wringer attached to a washing machine of a familiar type comprising a tub or receptacle for contaming the clothes and water, and provided with a beater or dolly mounted on a shaft depending, through the lid into the tub and adapted to be given an oscillatory, rotary movement by means of the driving mechanism, so that the clothes are agitated by a stirring motion, first in one direction and then in the reverse direction. A wringer of familiar type is attached to the top of the washing machine tub, and my improved operating mechanism includes means'for driving the'operating shaft of said wringer continuously in either direction, a reversing device being provided which may be adjusted to either of three positions, in two of which continuous rotary movement is imparted to the operating shaft of the wringer while in the intermediate position of said reversing device the driving mechanism has no effect to rotate said operating shaft of the .wringer.

My improved mechanism is particularly of advantage in connection with the use of power, although it may be operated by hand.

In the drawingsFigure 1 is a view representing in side elevation my improved operating mechanism when applied to the tub of a washing machine; Fig. 2 is a view representing a top plan view of the parts shown in Fig.1; Fig. 3 is a view representing on an enlarged scale, a partial vertical section through Fig. 1, in a plane indicated by the line 33 of Fig. 1; Fig. 4 is a detail side elevation of a part of the mechanism as looked at in the direction of the arrows 4-4 as shown in Fig. 5; Fig. 5 is a view in elevation representing, on an enlarged scale, a part'of the mechanism as viewed in the direction of the arrows indicated by '5-5 in Fig. 1; Fig. 6 is a detail sectional view taken in a plane indicated by the line 6-6 of Fig. 2; Fig. 7 is a viewrepresenting a transverse section through the part shown in Fig. 6, in the plane indicatedby the line 77 of Fig. 6.

'Referringl nowto that embodiment of my invention illustrated in :the drawings, 10 indicates a tub of familiar construction supported on upright. legs 11, 11. Said legs are rigidly braced apart near their lower ends by diagonally arranged bars 11*, 11, which also, as will presently appear, act to support the base board of a motor for driving the opera-ting mechanism. The tub has a hinged lid 12 connected by hinges 12 12 to a horizontal board 13 forming a part of the top closure of the tub. The top of the tub provides a support for the improved operating mechanism.

13 indicates the usual beater, fixed to the lower .end of a vertical shaft 14:,which depends through an aperture in the hinged lid and is rotatively suspended from a bearing formed in a base plate 15 secured to the hinged lid of the tub. Above 'the tub-lid is at one end a spur-gear 17 and projecting at its other end into a spherical shell creasing 18 within whi ch it has fixed to it a gear 19.

A bearing member 20 rises from the baseplate 15 and provides bearing for the shaft 16 at a place spaced from the shell 18. As shown in the drawings, the bearing member 20, the bearing plate 15 and one-half of the sphericalshell 18* are made in one casting. The other half of the shell 18 is punched from sheet metal and is adapted to be sprung upon an annular flange 18 formed in the cast-section of the shell and is hinged thereto by means of a loop 18 which is inserted through a slot 18 in the cast shell. 7

The vertical dolly shaft 14 extends through the casing 18 and the gear 19 at that end of the shaft 16 which projects into the casing 18, is adapted for engagement; with radial teeth 20 on a vertically. movable sleeve 21' feathered on said dolly shaft. Two

of said pins are provided. with prolonga tions 22 adapted when said sleeve reaches the limits of its intended amplitude of oscillation to engage with curved guide-plates 23 made rigid with the casing so as to hold said pins in engagement with the teeth of the gear 19. Thus the gear 19, though rotating continuously in one direction engages first the upper sides of the pins 20 and then on account of the endwise movement of the. sleeve 21 on the dolly shaft, brought about by the engagement of the pin prolongations 22 with the curved guide plates 23, engages on the lower side of said pins, so that a rotary oscillatory motion is imparted to the sleeve 21 and through it to the dolly-shaft 1 1. This construct-ion is familiar and needs no further description.

24 indicates v a short horizontal driving shaft located in the same vertical plane as the shaft 16 but at a level below said shaft and having. bearin in upright arms 25, 25 rising from a ase-plate 25 secured to the fixed top of the tub. A pinion 26 rig-- idly secured too'ne end of said shaft 24 meshes with the gear 17 at the outer end of the auxiliary driving shaft 16. To the other end of said shaft 24 is secured a large flywheel 27 having a grooved periphery so that it may act as'a pulley. As shown in the drawings, said pulley 27 is driven by an electric motor 28 mounted on aboard 29 rigidly secured in the angle of the cross bars 11*. The motor drives the fly-wheel and its shaft 2-1 continuously in one direction, and the shaft 2% in turn drives the shaft 16 continuously in one direction, and the cont-inuous rotation of the latter shaft is converted into a rotary, oscillatory movement of the dolly-shaft, as above explained. V

30 indicates the usual wringer board secured to the fixed top of the tub and pro vided with upright end boards 30 30, to which the ends of the wringer are clamped in a familiar manner. As shown herein, said wringer extends in a direction parallel to the driving shaft 24.

31 indicates the wringer, as awhole, and 32, 33, the rolls thereof. One of the wringer rolls, in this case, the lower roll, has a shaft 32 which projects beydnd the wringer frame, as clearly shown in Fig. 5. The shaft 32 beyond the wringer is journaled in upright spaced arms 35, 35, rising from the base-plate 25. On said shaft between the upright bearing arms 35 and abutting at either end against the inner faces of and arms, is rigidly secured a square bushing 36.

37, 38 indicate oppositely disposed beveled gears which, as will appear, are the reversing gears and which are made rigid with-a sleeve 39 mounted on the square bushing 36 and capable of endwise movement thereon.

4.0 indicates an auxiliary driving shaft extending at right angles to the wringer opermain driving shaft 24; and said shaft Said shaft 40 has bearing in arms -10, 10", rising from the base-plate 25. A beveled gear ll fixed to one end of the shaft 40 meshes with a beveled pinion keyed to the main driving shaft 24:. A beveled pin ion 43 secured to the other end of said shaft 410 is adapted for engagement with either of the beveled gears 37 and 38.

1% indicates a gear casing comprising shields 44?, 44 for covering and protecting the reversing gears 37, 38, and a shield 44: for the beveled pinion 43 which is adapted for driving said reversing gears, said shields being connected by an annular web 14, proatin shaft 32 and extending between the vided on its inner surface with a radial, an-.

nular flange etl. Said flange 14 engages within an annular groove 39 formed in the cylindric surface of the sleeve 39. A lever 45 (see F ig. is fulcrumed on an upright lug 45 rising from the base-plate 25. The upper end 16 of said lever has pivotal con-- iiection with the web 4.4of the gear casing 44 and its lower end 17 has pivotal connection with a link or bar 48 extending parallel to the wringer to a point beyond its right hand end, as shown in Fin 2.

To impart longitudinai movement to the sleeve 39 on its bushing 36 "o as to bring either of the beveled gears y 38 into en gagement with the beveled pinion on the auxiliary driving shaft 40 or into neutral. position and to lock it in any one of these three positions, the following mechanism is provided: 51 indicates a plate extending in a Vertical plane parallel tothe l 8 and made integral with a vertical h secured to the end board 30 of the \vringer board 30 which is farthest removed from the reversing gears and in this case at the righthand end of the wringer. A lever 52 is pivot-ally connected to said plate and its lower end has pivotal connection with the link-bar 48. The base-plate 51 has a slotted depending projection 51 which provides a guide for the link 48 adjacent the lever 52. It is apparent that by swinging said lever 52 toward or away from the 'wringer, the desired movement of the sleeve 39 carrying the beveled gears 37, 38 may be brought about; ,The plate 51 is provided with three holes 53, 54, 55, arranged in the are of a circle and corresponding in posi- 'tion, respectively, with a position of the sleeve when the gear 38 is in mesh with the pinion 43, with a neutral position of said sleeve and with a position of said sleeve when the gear 37 is in mesh with said pinion The lever '52 is made rigid with a short shaft 52 (see Fig. t), which has hearing at one end in an aperture in the plate 51 and at its other end in a lug 51 rigid with the base-plate 51 and spaced from said plate .51. A coiled spring 56 is mounted on said disengage the pin 52' from the hole within which it is engaged whereupon said lever may be swung to bring the pin opposite either one of the other holes corresponding to the desired position of the sleeve carrying the reversing gears 37, 38, whereupon the pressure of the hand on the lever is released andthe pressure of the spring against the lever causes the pin to engage in the hole opposite to which it is placed, so as to lock said sleeve in either of the desired positions.

The gear 17 is covered by means of a shield plate 17 securedtothe top of the bearing member 2-0. The beveled gear 41 is likewise covered by a shield plate suitably formed to inclose it on top, said plate being secured to the upright bearing arm 25 rising from the base-plate 25.

It will be noted that in the arrangement of the device for shifting the reversing gears, the lever for operating the same is located at the right-hand end of the wringer, as is shown in Fig. 2, so that when the tub lid is open, the person using the washing machine naturally stands on the right-hand side of the tub in a position more or less facing the driving pulley and the wringer, and the right-hand is in position to reach the operating lever with ease in orderto stop the wringer or to start it into operation in either direction;

It is apparent from the construction described, that when-the lid is open, the gear 17 is disengaged from the pinion 26, which drives it so that the continued rotation of the fly-wheel pulley andv the parts driven thereby will have no effect on the dollyshaft which remains at rest until the lid is' mon base-plate 25 supported on the top of the tub. By reason of this construction, the alinement of the several shafts is always maintained, and there is no danger of the gears becoming disengaged or inoperative by reason of the warping or other deformation of the top of the tub.
