GEARING.

Application filed June 3, 1912. Serial No. 701,130.

To all whom it may concern:

Be it known that I, ABBA VAN Worm,

a citizen of the United States, and a resi dent of Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Gearing; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe ac companying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in operating gearing and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The improvement in gearing, as shown herein, is applied to a washing machine and is used for imparting oscillating, rotary movement to the beater or dolly shaft of a washing machine. Said gearing is of the type which may be operated by an oscillatory lever and includes a continuously rotative fiy-wheel which, by its acquired momentum, acts to reduce the effort necessary to keep the gearing in operation after it has started.

In the drawings :-Figure 1 is a View representing a top plan of a washing machine provided with my improved gearing. Fig. 2 is a view representing a similar plan showing a slightly modified form of the construction. Fig. 3 is a view representing a side elevation of the machine shown in Fig. .1.

Fig. 4 is a view representing on an en-" larged scale a partial vertical section through the gearing in a lane indicated by the line 4-4 of Fig. 1. ig. 5 is a view representing a vertical section, on an enlarged scale, through the gearing shown in Fig. 1 in a plane indicated by the line 55 of Fig. 1. Fig. 6 is a view representing a like section taken in a plane indicated-by the line 6 -6 of Fig. 2. Fig. 7 is a detail side elevation of a pulley and pinion fixed thereto which may be used when the gearing is intended to be driven from a main power shaft. Fig. 8 is a view representing a vertical section through the gearin in a.

plane indicated by the line 88 of' ig. 1.

- Referring now to that embodiment of my invention illustrated in the drawings, 10 indicates the support for the operating mechanism or gearing which in this case is a washing machine tub of familiar construction standing on upright legs 11, 11, which are connected by cross-braces 12. The support has a hinged member 13, which, in this case, consists of the hinged lid of the tu 14 indicates a fixed horizontal board attached to the top of the tub and constitutinga part of the top closure thereof. The

top is also usually provided with a second fixed part 15 which, as shown, extends at right angles to the fixed part 14 and acts as a support for the wringer where a wringer is used.

16 indicates the usual dolly shaft which depends within the tub. Said shaft carries a dasher or beater 17 at its lower end and its upper end extends through the hinged lid 13. Asshown, said dolly shaft 16 has bearing in a bearing plate 18 bolted to the lid and extending from the center of the lid in a direction parallel to the hinged side of the same.

19 indicates a beveled pinion fixed to the upper end of the dolly shaft 16 and having lid and on the side of the bearing 21 nearest said. center there is fixed to said shaft a beveled segmental gear 21" which meshes with the beveled pinion 19. At the outer end'of the shaft 20 and on the outer side of the bearing arm 21 there is fixed to the shaft 20 a crank arm 23, which, as shown, has a bifurcated end. The shaft 20 is retained against longitudinal movement in its bearing by means of the se mental gear 21" and the crank-arm 23 which have thrust bearing a ainst the faces of the bearing arms to w ich they are adjacent.

On the vertical side of the support, in this case of the washing machine tub, is secured a bearing plate 24 which has a vertical part 25 bolted to the side of the tub and a horizontal flange 26 at its upper edge near one end which is bolted to the fixed part 14 of the tub top. Said bearing'plate also has preferably'a narrow flange 25 (see is which is" adapted for theattachment ofa',

' back unovmentffor the operator in. eper atingthegearing, whereas thefo'th'er, 27

[is in a substantially horizontal position {so as to 'provideanup and downpiimp-handles motion for operating the gearing. f J 1 29 indicates an arm formingpar't of thel '35 rocking member'27, said arm extending, as shown, i'n-a direction parallel to the axis of the 'socketf2'? and-in 'adi'rection at right an lesm the axis of the socket 27 Said;

arm is bifurcated and between its bifurcated "'1'0' elidsthereis pivoted'one end ofa link 30.:

"Theopp'osite end of said link is divided and.

'- jhas two laterally s ac arms 31,32flh'1at 5 at being shorter than the former. The end 7, of the l1nk-arm'32'is connected by a link 33 ME With the-bifurcated end of the crank-arm23 on the end" of the'shaft 20. The link arm 31 "constitutes a pitman or connecting rod and is pivotally connected to a crank-pin 33 on a. large gear 33 rotatively supported by the ED bearing plate 20' and in mesh with a pinion 34"fixed-to ormade rigid with the'hub of a v fly-wheel 35; that is also rotatively supported by the bearing late 24 in a vertical planespaced from thep ane of the large gear 33.-

"" The pitman 31 thus extends between the planes of the gear 33 and the fiy-wheel 35.--

. In that form of my invention shown in Figs. 1 and 5 of the drawings, the large gear 33" is loosely mounted on a horizontal stub-shaft 36 that has bearing in an arm 37' rising from the horizontal flange 26 at the rear end of the bearing plate 24; The plane I of the gear 33 is laterally spaced from the bearing arm 37, thespacebeing filled by a washer or,sleeve 38.- I prefer to provide the .gear wheel 33 with an a erture 39 formed, as shown, in one of its spo es at a point radi- ,ally spaced from its center, which aperture -is adapted to receive a bolt which constl- *tutes t e crank-pin 33.

The. construction described is for use where hand power is used and the wringer, when placed on the tub is not connected with the gearing that-operates the dolly. For use-when the gearing is operated by a motor 01' other power device, as will presently be described, I provide a shaft which ma be readily substituted in place of the s ort stub-shaft 36, said auxiliary shaft being provided with a coupling by means of which it may be'conn'ected Wlth a reversing mechanismfor operating the wringer. Such shaft is shown in Figs. 2 and 6, thesame bein indicated at 4:0. Said shaft extends paralle to the operating shaft 20 on the tub-lid and thus at right angles to the axis of a wringer 41 that is secured on the fixed part 15 of the tub. top. 1 In connection with this shaft I provide a sleeve'42'having-a radial arm 43 I withflan aperture which when-the sleeve 43- on the shaft will register with the aper- 1 ture occupied by the crank-pin bolt 33 above referred to. I=also provide asecond washer 44 to be located on the shaft 40 at the inner side of the bearing arm '37,- Thus when the"-gj5 'machine is intended to be used as a power washer and the gearing is to be used connection with a reversing gearing adapted for operatinga wringer, the shaft 40 may be substituted for the-stub-shaft 36, the washer 142 for the washer 38 and its radial arm connected to the crank-pin bolt; Said washer is pinned to the shaft and the washer-4:4 is placed on the otherside of "the bearing arm 37 and pinned to the shaft. In this we 1 the "'10 large gear is.rigidl v. attached to the sha t 40. The operation: ofjmyimproved gearing is apparent r from the above description; By swinging the lever 28-oscillatory motion is imparted tothe radial arm 29 of the rocking member and from said radial arm by the link 30 and particularly the arm 32 thereof,

said oscillatory motion is converted into a rotary continuous movement of the gear 33" which; through the pinion 34, causes a vcontinuousrotation of the fiy-wheel 35. Through the arm 32 of the link 30 and the link 33, an oscillatory movement is communicated to the crank-arm 23 which, through. the operating shaft 20 and segmental gear"12 21, is imparted to the bevel pinion 19 at the upper end of the dolly shaft, causing a ro-- tary oscillatory movement of said dolly shaft." If desired, the gearing may be driven by a motor mounted below the tub instead of by hand through the lever28. In this case the drive pulley of the motor is connected .by a belt to the fly-wheel, as indicated by dotted lines in Fig. 3. 50 indicates an electric motor supported in any convenient manner on the cross-bars 12 that connect the legs of the tub and having a "shaft which projects through the leg and. carries a pulley 51. 52 indicates a belt connecting said driving pulley with the flywheel 35 which is provided with a groove in its periphery to accommodate the beltf Instead of the small motor carried by the tub itself the mechanism may be driven from a mainpower shaft that is used for driving other machinery. For such purpose, I prefer to provide the pulley .53 and pinionp54rzfixed i as to, hold it friotiona'llywith" theretdillustrated in Fig. 7, which may be substituted in place of the fly-wheel 35*and its pinion 34. To lock the hinged lid 13 of the tub in closed position during the washingoperation, 1 provide a projecting lug on the bearing plate 18 carried by the tub lid. 55; indicates an upright luv on the bearingplate 24: carried at the side of the tub.
