GARING FOR WASHING-MACHINES.

Application led March 2G, 1917.

To all whom t may concern Be it known that I, WILLIAM JAcKsoN Scsoonovnn, a citizen of the United States, and a resident of Belvidere, in the county of Boone and State of Illinois, have invented certain new and useful Improvements in Gearing for lVashing-lvlachines, of which the following is a full, clear, and exact specification.

My invention is concerned with gearing for washing machines, and is designed to produce a gearing of the class described that shall be suitable primarily for hand-operated lever washing-machines of the vacuum or pounder type, in which the operating mechanism extends upward through the bottomv of the tub.

It is concerned more especially with a gearing of the class described in which the {1y-wheel rotates in a horizontal plane, and

also with a novel form of mechanism for rotating the spider carrying the cups on the non-rotating shaft that reciprocates up and down through the bottom of the tub.

To illustrate my invention, I have annexed hereto foursheets of drawings, lin which the same reference characters are used to designate identical parts in all the figures. of which,-`

Figure l isV a central vertical section through a washing-machine employing my novel gearing;

Fig. 2 is a topplan view as seen in section on the line 2-2 of Fig. l;

I yhave shown my invention as applied to e5 the ordinary tub 10 having the four :legs 11,

the bottom 12, and the lid 1'3 which is hinged Specification of Letters Patent.

on the top of the tub in any suitable man ner so that it can be lifted to remove the contents or observe the operation of the ma.- chine. rIo gain additional space for the gearing, I preferably employ the cap 14e covering an aperture l5 in the lid located centrally of the tub.

Pivoted in a fulcrumed bracket 16 suitably secured on the side of the tub is the operating l1and-lever l?, which may be of any desired construction, and which may be provided with the stirrup 18 at its lower end, so that foot-power can also be applied. Pivotally connected nearthe lower end of the hand lever 17 is the pitman I9, the other end of which is pivoted on the eccentric bearing pin 20 mounted in the bevel gearwheel 21 mounted to rotate on the horizontal stub shaft 22 pinned in the bearing bracket 23, `which in turn is secured, as by the set screw 9.4, on the upper end of the verticalV bearing shaft 25, Ythe lower end of which is seated in and supported by the bearing Q6 formed in 'the main horizontal portion 27 of a bearing bracket which is secured on the two cross pieces 98 which are secured to and connect the lower portions of the legs l1. T he last-mentioned bearing bracket has the pair of horizontal portions 29, each of which has the short upright. portions 30 having the shape of an angle iron, and running into the inclined portions 3l having the same cross section, which inclined portions in turn run into theelon'f` gated vertical portions 3;?, which in turn are preferably connected atV their upper ends by the horizontal plate 33 which rests against the under side'of the bottom of the tub and is conveniently secured thereto by the nut Sil screwed on the threaded` lower end of the vertical bearing-sleeve 35, which is mounted in the center of the bottom of the tub, it having the horizontal flange 36 resting on said bottom, as clearly seen in Fig. l. To steady` the movement of the gearing and avoid the possibility` of its stopping on dead centers, I journal onv the upright bearing? shaft ,25, between the vbracket 9.51 and the bearing 2G, the hub of a heavy fiy-wheelll, which has the bevel pinion-38 secured there on meshing with thebevel gear-wheel 21, so that as the handle 17 is swung back and forth slowly., the fiy-wheelgi will be rotated at a comparatively high speed. y

Mounted to reciprocate in the vertical bearing-sleeve tmisfthe .vertical shaft 3l), y

which has the spider 40 secured on its upper end by the mechanism which will be hereinafter described. Secured on the lower end of this shaft 39 is a guide plate having the collar 41 at its back, which is pinned to the lower end of the rod 39, the guide plate proper 42 having a pair of parallel, horizontal flanges between which reciprocates the elongated sliding block 43 pinned on the Vadjacent end of the shaft 20, which is free to turn in its bearing in the bevel gear-wheel 21. By the connections thus described, it will be obvious that the shaft 39 will be reciprocated each time the handle 17 is reciprocated, and it will further be observed that the guide plate 42 is in turn guided in its vertical movement byY its contact with the vertical portions 32 ofthe main bearing bracket located beneath the tub.

The vspider 40 has the central hub 44 and the downwardly and outwardly extended arms 45, which have the plurality, preferably three, of cups 46 secured on the ends thereof to engage the clothes being washed in theV customary manner. The spider is free to rotate on the upper end of the shaft, which isprovided with the annular groove 47, into which is swung the latchpiece 48,

best seen in Fig. 10, which is pivoted at 49 and can swing'back and forth in the horizontal recess 50 formed in the hub 44 to accommodate it. A latch 51 is pivoted to the hub at 52 and swings down over the latch 48 and holds the same in its operative position. With the construction just described, it will be obvious that the spider 40 is free to rotate on the upper end of the shaft 39, but that it can be readily removed, when desired, by raising the lid, raising the latch 51, and finally swinging out the latch 48. By this simple connection, I can easily remove the spider and the cups 46, as is desirable in putting in a fresh lot of clothes or in wringing out those that have'been already washed.

Togive the spider 40, 'and consequently the cups 46, slight angular movement about the shaft 39 at each reciprocation so that the cups will strike the clothes in a new place each time, VI employ the follow ing mechanism-z Secured near the upper end of fthe shaft i 39, as best seen in Fig. 5, by the set-screw 53,is the collar 54, in which is mounted eccentrically the rod 55, the upper end of which is circular and uis free to rotate in the circular aperture in the collar 54 through which it passes. y A flanged collar 56 'secured onthe upper end of the rodl rests o n the collar 54, and nivoted loosely on lthe upper end of Ithis-collr-ar `-,56, as bythe pin 5.7is a dog 58, the 'shape of which is best seen in Y, the overweighted nose of which tends to engage thelteeth '59 formed on theunder side ofthe hub 44, preferably by being stamped into periphery of theA circularV plate 60 secured on the under side of the hub. The' portion of the rod 55 below the collar 54 is square in cross section, and cooperates with a snugly fitting squared aperture 6l formed at one side in the top of the sleeve 35. This sleeve 35 carries the rib 62 extending along one side thereof, and the aperture 6l is located in the rib 62. The squared aperture 61 leads into al larger cir-V cular aperture 63 extending the vlength of the rib 62 to accommodate the twisted portion of the rod 55, which is twisted so as to causey it to be given a slight rotation as it rises and falls throughthe squared aperture 61 during lthe reciprocation of the rod 39. This rotation causes the dog 58 to swing over a sufficient number of ratchet teeth 59V out its purposes, it will be understood that i it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims eXcept as may be necessitated by the state of the prior art.
