GEARIN G FOR WASHING-MACHINES.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed September 27. 1905. $erial No. 280.348.

T 0 all whom it may concern:

Be it known that I, HUGH H. MUNSON, a citizen of the United States, residing at Truro, in the county of Madison and State of Iowa, have invented a certain new and useful Gearing for Washing-Machines, of which the following is a specification.

The objects of my invention are to provide a light running gearing for washing machines of simple, durable and inexpensive construction which can be readily attached to the cover of any of the ordinary makes of washing machines and which is so constructed as to impart a reciprocating motion to the agitator from a handle operating in a horizontal plane.

A further object is to provide a sprocket wheel in the gearing which is directly operated through a sprocket chain which is reciprocated by the handle.

My invention consists in certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 is a rear elevation of the washing machine with the rear upper portion of it broken away to show the agitator. Fig. 2 is a plan view of the washing machine with my gearing attached to it. Fig. 3 is a sectional view of the gearing and the cover of a washing machine, taken on the line 3-3 of Fig. 2, and Fig. 4 is a detail view of the roller bearing in which the agitator shaft operates.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the tub of the washing machine which is mounted on the legs 11. Hinged to the upper portion of the washing machine is a cover 12 constructed in the ordinary way. Extending through the central portion of the cover is an opening 13. Attached to the upper portion of the cover is a frame preferably cast in a single piece which comprises a flat plate 14 from which the bearing 15 downwardly extends, entering the opening 13, which, together with the screws passing through the frame into the cover, maintain the gearing in position relative .to the cover. These screws 1 have designated by the numeral 16. Extending upwardly from one end of the plate 14 is a curved roller bearing support 17 having an opening 18 extending through it, which opening is substantially in nal diameter line with the opening 13. Outside and above the opening 13 is a roller bearing groove 19 designed to admit a series of rollers 20 therein. Extending through the openings 13 and 18 is the agitator shaft 21 having the agitator 22 detachably connected with its lowerend. The upper end of the agitatorshaft 21 is screw threaded and a nut 23 is screwed to it to retain the rollers 20 in the roller bearing groove 19, as shown clearly in Fig.3 of the drawings.

Mounted on the shaft 13 in such a way that the lower surface of its hub engages the upper surface of the plate 14 is a sprocket wheel 24, which sprocket wheel has a longer longitudithan a cross diameter and is very nearly elliptical. Extending upwardly from the opposite end of the plate 14 from the curved roller bearing support '17 is a post 25 on which is mounted a sprocket chain holder having the two arms 26 and 27 therein. At the outer end of the arm 26 is a -hook 28, and at the outer end of the arm 27 is the hook 29. There is a nut 30 designed to be screwed on the upper screw threadedportion of the post 25 designed to maintain the sprocket chain holder in position on the post. Secured to the rear central portion of the sprocket chain holder by means of a thumb screw 31 is a handle 32 by which the gearing is operated. Connecting the hook 28 and 29 on the sprocket chain holder is a sprocket chain 33 which constantly engages sprocket wheel 24 which is away from the post 25 as the machine is operated. I

In practical operation and assuming that the device is set up for use as above described, and that the handle is oscillated, the s rocket chain will be drawn to the right and eft and cause the sprocket wheel to be reciprocated and also cause a reciprocation of the agitator. On account of the construction of the sprocket wheel 24, the sprocket chain will be constantly held taut as it is operated, and as this wheel is substantially elliptical in that portion of the shape, the wheel will have the longest leverv grasped i Q I 877,106
