To all whom it may concern:

Be It known that I, WILLIAM H. Voss, a citizen of the United States, and a resident of.

. Davenport, in the county of Scott and State able elevation by legs a, and

of Iowa, have invented certain new and useful Improvements in Mechanical Movements for Washing-Machines," of which the following is a clear, full, and exact description.

My invention relates to the actuating mechanism of washing machines, and its obj ect is to provide means for utilizing the momentum of a fly-wheel to assist in actuating a stirrer-shaft driven by a reciprocating lever and particularly the reversing movement of said shaft and thus greatly assist in rendering the manual working of the machine less arduous. This I accomplish by the mechanism hereinafter fully described and as particularly pointed out in the claims.

In the drawings :Figure'.l is a side elevation of a washing machine having my improvements applied thereto. Fig. 2 is a vertical central section thereof taken on dotted line 22, Fig. 3. Fig. 3 is a plan view. Fig. 4 is a detail view showing the gear connecting the reciprocating lever and stirrer-shaft] on a slightly larger scale.

. Referring to the drawings A represents the tub of a washing machine supported at a suitrepresents the cover of the tub hinged, as shown in Fig. .3, to

the segmental top piece I) that is securely fastened to the upper edge of the tub.

C represents a rotar reciprocal stirrershaft, which is journale in suitable bearings c in the center of the cover B, and has a suitable stirrer-head C secured on its lower end within the tub. Above its bearings the stirrer-shaft is made square in cross-section and extends up through a pinion D, with which it rotates but can move independently in a longitudinal direction. This stirrer-shaft, after passing through the boss of pinion D, extends up into a suitable sleeve journaled in the vertical bearing 6, supported in the u per end of the frame E. Bearing e is'of such ength that its-lower end engages the upper end of the boss of the gear and prevents its displace.- ment from the position shown in the drawlugs.-

which is fulcrumed a lever F. whose upper ortion is provided with a handle of sufficient ength, and Whoselowerportion is formed into a segmental gear 9 that engages the upwardly Projecting laterally from the upper end of the bearing 6, is a suitable stud f upon projecting teeth h of a straight horizontally disposed double rack G.

ltack G is provided with a series of laterally projecting teeth j that mesh with gearD, with which it is he t in engagement by means of a squared horizontal guide-bar I-I, upon which guide-lugs I, I, projecting from the ends of said rack, are slidingly mounted. This guide-bar is maintained in about the same horizontal plane as the gear D and rack G, by havingits ends secured in short standards 7c, is, removably secured to the cover, substantially as shown.

At one end the rackG is-provided with upwardly projecting pivotal lugs m, between which the adjacent end of a horizontally disosed link J is, preferably, removably secured.

his link extends in the same direction as rack G, and has its end farthest from the rack pivotally and adjustably connected to the upper end of a rocking-beam K, which latter is fulcrumed between the lugs of a bracket M, suitably secured to the side of the tub near its bottom. The lower end of beam K extends to a suitablepoint below the plane of the bottom of the tub, and is connected by a pitman N to the crank-pin of gear 0, journaled on a stud projecting laterally from the lower extremity of an L-shaped hanger I, which latter is secured to and depends down from the bottom of the tub. T his gear 0 engages a pinion 1' on the adjacent end of a horizontal shaft Q, journaled in bearings in the angle or bend of the hanger P, and in bearings R depending from the bottom of the tub near its circumference, and has a suitable flywheel T secured to its outer end.

In 0 eration, when the lever F is reciprocated ack and forth, the segmental gear 9 engages and reciprocates rack G, which, through the medium of the pinion I) imparts a rotary reci n'ocal movement to the stirrershaft and stirrer-head. cates it rocks the beam K, through the mediumof the link J, and said beam by means of the pitman N revolves gear 0, and the latter drives shaft Q through pinion 1', with which it intermeshes. When the shaft Q is revolved the fly-wheel im )arts a momentum thereto, which, through the train of the mechanical devices illustrated and described, materially assists in actuating the rack G, and in reversing the same at the ends of the reciprocal throw thereof, and thus lessens the expenditure of physical force, which heretoforewas demanded of the operator, particularly when reversing the movement of the stirrer-shaft-at each end,

of the reciprocal throw of lever F. Y
