Specification of Letters Patent.

Patented Mar. 27, 1217.

Application filed May 22, 1916. Serial N0. 99,051.

To all whom it may concern:

Be it known that I, GLENN More, a citi- Zen of the United States, and a resident of Jamestown, in the coun of Chautauqua and State of New York, have invented certain new and useful Improvements in Qperating Gearing for Washing Machines; 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, which form a part of this specification.

This invention relates to improvements in operating mechanism for washing machines and the like and consists of the matters hereinafter described and more particularly pointed out in the appended claims. 7

One object of my invention is to provide a simple, effective device in which a part of the operating mechanism is mounted upon a fixed support and another part upon a movable support but in which the two sets of mechanisms are constantly in operative connection, whereby the movable support may be moved from its normal position or retained operatively therein, without the necessity of connecting or disconnecting any of the operative elements of the mechanism.

Another object of the invention is to provide a mechanism wherein when the prime mover is actuated manually, the force of the power exerted by the operator is applied with substantial directness to the operating shaft and also is materially assisted by a high speeded fly wheel operatively connected to said prime mover.

These objects and the many advantages of my improved operating mechanism will appear as I proceed with my specification.

In the drawings:

Figure 1 represents a view in side elevation of a washing machine provided with my improved operating mechanism.

Fig. 2 represents a top plan view thereof.

Fig. 3' represents a view similar to that shown in Fig. 1 but with the parts in a changed relation.

Figs. 4 and 5 represent detail sectional views on an enlarged scale, through parts of my improved operating mechanism, the planes of said sections being indicated by the lines 44 and 5-5 respectively of Fig. 2.

Referring now to that embodiment of my invention illustrated in the accompanying drawings, 10 indicates the tub body of a washing machine which is mounted upon upright supporting legs 11 in the familiar manner. The tub body 10 has a stationary top wall 12 to which a lid 13 is hinged along one edge 13 as hereinafter described. Said stationary top wall 12 and lid 13 in this case provide supports for the operating mechamsm.

14 indicates an upright, vertically reciprocating beater shaft which projects through the tub lid 13. Said shaft is arranged, preferably, coaxially with respect to the tub body 10 and has a beater head 15 fixed to that end within the tub body. The shaft 14 has sliding bearing in a sleeve 16 which projects through a suitable aperture in the tub lid 13, and said sleeve is made integral with a bracket plate 17 fixed to and supported upon the top surface of said lid. The opposite or top end of said heater shaft 14 has fixed to it, a collar 18, to which is operatively connected the means for imparting a vertical reciprocating movement to saidshaft.

The bracket plate 17 extends toward that edge 13 of the lid which engages the stationary top wall 12 of the tub body. Adjacent said edge, said bracket 17 is provided with -upright spaced standards 1919 which have laterally extending arms 20-20% normally horizontal, adapted for hinged connection with upright standards 2121 made integral with a bracket casting or plate 22 fixed to and supported upon the stationary top wall 12 of the tub body.

23 indicates a horizontally disposed shaft which is fixed at its ends in suitable apertures formed in the top ends of the upright standards 19-19 of the bracket plate 17, said shaft being arranged parallel with the edge 13 of the lid 13. Loosely mounted in said shaft, so as to rock thereon, is a bell crank-prime mover-lever, indicated as a whole by the numeral 24.

The prime mover or lever 24 has an arm 25, disposed in a substantially horizontal direction, which extends into the vicinity of the heater or operating shaft 14. The end 25 of said arm is preferably forked and operatively connected to the collar 18 at the top end of said beater shaft. Said prime mover or lever 24 also includes a substantially upright or vertically arranged 7 their top ends, respectively, with axially ar-' ranged studs 21 21, extending parallel with the shaft 23 before mentioned. The

outer ends of the horizontal arms 2020 of the bracket plate 17 are provided with suitable bearing apertures to engage said studs 21 and, 21, thereby providing a hinged connection between said movable support or lid 13 and the stationary support or topwall 12. ,Rotatively mounted on one of the studs (in this instance, the stud 21 is a spur gear 32 of comparatively large diameter (see Fig. 4), which gear meshes with a smaller bevel gear 33 fixed to the inner end of a shaft 34. Said shaft 34 is journaled in a bearing sleeve 35 made integral with the bracket casting 22. It will be observed that said shaft 34 and its associated bearing sleeve are positioned adjacent to the proximate edges of the supports 12and l3, and that the axis of said shaft 34 is parallel with'the edge 13 of the lid or support 13. A fly wheel 36 is fixed upon the outer end of the shaft 34, beyond the bearing sleeve 35.

The gear 32 has a crank pin 37 which is operatively connected by means of a link or pitman 38, to the arm 28 of the prime mover or lever 24, whereby said gear is caused to rotate by the oscillating movement of the lever arm 28.

Made integral with the upright bearing about the studs21"21 of the bracket plate 22 into the desired openor substantially verticalposition, the shoulder 40 on the arm 20 will engage upon the shoulder 39 .on the uprightarm 21 and thus prevent the lid from'being further moved in that direction and also support it in the desired open position. A gear cover or guard 41 isfixed in. position upon the upright bearing arm 21 of the bracket 22 in a manner to protect the gears 32433 against breakage and also against'accidental engagement of the person or clothing of the operator.

The operation'of my improved operating mechanism is as follows:

With the clothing or other garments in the tub body, the tub lid 13 is locked in its closed position in the usual manner. The

operator next grasps the handle 27 of the prime mover lever and imparts a back and forth rocking movement thereto about the shaft 23 as an axis. Through the opera tive connections before mentioned, the horizontal arm 25 will impart a vertically reciprocating movement to said shaft, and the beater l5 fixed to the lower end of said shaft will operate to clean the clothing within said tub. On account of the connection afforded by the link 38 between the arm 28 of said prime mover lever and the crank pin 37 on the large gear 32, said gear will be continuously rotated in one direction and this rotative motion will be transmitted to the small gear 33 on the fly wheel shaft 34, at a considerably higher is first unlocked. It may now be swung from its horizontal or closed position, about the studs 21"-21, as an axis, into an open, substantially vertical position, and held in said position by reason of the engagement of the lugs 39 and 40 before mentioned.

- My improved operating mechanism possesses many advantages, one of which is that but a small portion of said mechanism is mounted on the movable support or lid, thus making it possible to open said lid but with little effort on the part of the operator. As will be apparent, the heavier parts of the mechanism are mounted on the stationary support or top of the tub. This relieves the lid from the great stress and strain when the device is being operated and also affords a little better balance to the whole device as a unitary portable structure.

Another advantage is that, accidental closing of the lid 13 when the same is in an open position, is impossible as the greater part of the weight of the mechanism carried thereby is located in a plane back of the vertical plane of said lugs 21"21 which forms the pintle of the hinge connection between the stationary top 12 of the'tub and the lid 13. -This follows from the relative location of the lugs 39 and 40 when engaged, as compared with the location of the axis of pins 21 and 21.
