To all whom it may concern:

Be it known that It, WILLIAM RUTHVEN, acitizen of theUnited States, and resident of Chicago, in the county of Cook and State oflllinois, have invented certain new and useful Improvements in' Gearing for Washing-Machines, of which the following is a full, clear, and exact specification.

My invention is concerned with a novel mechanism primarily designed for transforming the swinging movement of the operating lever of a washing machine into the rotary movement of the stirrer highspeed rotary movement of the fly wheel associated therewith, to give evenness and ease of operation tosuch machines, despite the reciprocating movement of the main parts thereof.- a i To illustrate my invention, I annex hereto a sheet of drawings, in which the same refer'ence characters are used to designate identical parts in all the figures, of which,-

Figure l is a top plan view of a machine embodying my invention in its preferred form; Fig. 2 is a side elevation of the same; Fig. 3 is a top plan view of the casting forming the bearing for the various elements of, the mechanism; and Fig. 4 is an inverted pla n view of the transmission lever.

My invention is adapted to be employed in connection with a tub 10 of the ordinary construction, which is supported at a suit able height by legs, the lid 11 hinged thereto, as at 12, and the ,entire gearing is preferably carried by said "lid, so that when it is raised, the gearing moves with it. v The heater shaft, the upper end of which is indicated in dotted lines at 13, is journaled in the bearing 141 formed on the end of the bearing casting 15, shown detached in Fig. 3, which is secured to the lid inany suitable manner, as by the screws or bolts 16. This beater shaft carries on the upper end the pinion 17 likewise indicated in dotted lines in Fig. 1. The handle l8 is secured in theisocket 19 of the lever casting 20, which has the bearing aperture'by which the lever is mounted to swing upon the hearing pin 21 projecting horizontally from the angle of the casting 15. This lever casting 20 has projecting downwardly therefrom the arm 22 carrying the which has the link Qtpivoted thereon at one end, theother end of said link being pivoted upon the eccentric bearing pin 25 secured to not shown, and which has eccentric pin 23,

the gear wheel 26, which is mounted upon the horizontal bearing pin 27 projecting from the end of the casting 15. The inter- -m'edi at'e remaining horizontal bearing pin 28, likewise projecting from the casting 15,

has journa-led thereon hub of which has secured thereto or formed integrally therewith the pinion 30, which meshes with the gear wheels 20, so that as the handle or lever 18 is swung, thefly wheel 29 will be rotated at a high rate of speed to furnish the necessary momentum for an even and easy operation of the machine, The lever casting 2O likewise has formed thereon, opposite to the arm 22,. the segmental bevel gear teeth 31, which ing set of bevel gear teeth 32, which, in my preferred form, are carried by the adjacent end of the transmission lever '33, which is pivoted intermediate its ends upon the bearing pin 34- proj casting 15. The lever 33 has ro'ectin downwardly from p J 6 its other endthe segmental gear teeth 34, which are preferably of the internal type, so as to cover the pinion l7 and prevent the" possibility of an thin being eairght therein; and to further securh 'this end, 1 preferably extend along the sides of the lever the downwardly projecting flanges 35', so that the pinion 1'? is practically mesh with a correspond 1 Patented Sept. 28, 19ml,

the fly wheel 29, the

ectin'g vertically from the entirely inclosed. It will be readily apparent that when the lever or handle 18' is pergive ment suitably pivoted to the casting 15, and the two segments be connected by a link.

VVhil'e I have shown and described my ventionas embodied in the form which I at present consider'hest adapted to carry out its purposes, it wiiibe understood that it is capahle'ot mcdificatibns, and that I do not desire to'he limited in the interpretation of rotary motion-to the heater and 34 as carried upon,

each setof said: teeth might be carried upon a separate seg 5 the following elai'r'nsexcept as may be necessita'wd by thestat'e of the prior art'. I
