To all whomit may concern: ft",

Be it knoivnthat I-, Wnmn H. Grouse,- a citizen of the United States of America, and residentbfDext'er; Dallas count Iowa, have invented a new and useful Mechanism for Washing- Machines, of'whic the following isl-a s'p'ecification.'

The: object of this invention'is toprovide improved means for operating the rubbing mechanism-ofawashing mac inei 1 -A further objectfbfthisinvention' is to provide=improved means for gearing" a bah;

arrangement and combination of elements hereinafterset" fortli';' poiiited outfinij my' claims and illustrated bythe" accompanying Figure l is a 'side elevation of-the niachine; Fi' 2 isan elevation of th'mecliine at right angles to. Figs} Fig; :3 a qilan of the machine.- Fig. 4 is'a bottomplan "of the machine.- v r y In the 'constructionf'of the machine as shown, the numeral designates abontaim' ing vessel or tub, which may be-of any desired form and construction, and with a. hinged cover 11. Am agitator is mounted on the lower end portion of'a" shaft 12- vertically positioned in and extending through the center ofthe cover 11; and a pinion 13' is mounted ri idly on the upper end portion of said-she above said cover. A bearing-plate 14-.- is fixed to the central portion or the bottom 15 of the tub 10, and,-

extending radially thereof, (projects at one end beyond the wall of sai tub. A lever 16 is fulciumed neurjits lower end in a bearing IT'formed on the outwardly projecting end portion of the plate 14, and

I said lever occupies an upright position norzontally mally. A lever 18 is fulcrumcd at its center on a bearing 19 fixed to and projecting horifrom the wall of the tub 10 diametrically opposite-the lever 16. The lever 18 normally occupies an upri ht position and is spaced apart from the \va 1 of the tub. The lever 18 has its end portions curved outwardly relative to the wall of the tub, and the upper end of said lever is hinged to one end portion of apitman 20. The pitman 20 is formed with a rack 21 on its innerv end portion, adapted to mesh with the pmion 13, and a roller 22 is pivoted on the cover 11 andengages the outer face of .the

rivin provided iametrically of the bot-tom 15 of thetub. A shaft 24 is journaled in a bearing 25 formed on the'pl'ate 14 adjacent the center of the bottom 15','-and also is journaled in a bearin 26 fixed to said bottom a jacent the rim't ereof. The shaft-24 extends trans-- July 26,1910;

pitman to hold the rack in mesh. A pitvman=.3 pivotally connects the lower end portions of the levers 16 and 18 and extends p 4 versely'oi the tub approximately at right anglesto the relatively same on the inner end' portion of the sha and meshes with a; spur gear 28 of relatively large'diameter, which spur gear is mounted diameter is mounted rigidly itman 23.- -A'p1mon 27 of on a stub axle 29 carried by a bearin 3O formed on and extendingdownward rom the plate 14L} The spur gear 28 is located adj a'cent the pitn'ian 23, and the axis thereof .is parallel with the axis of the shaft 24.

A wristspin -31 is niounted on the spur gear 28, and a pitman 32 connects said wrist-pin to the lower end portion of the lever-16.

The pitmen 23 and 32 are on opposite sides ,of lever 16 and spur gear 28and have.- a common point of articulation on said lever.

Suitable means may be em loyed to latch the cover 11 .to the tub; an I show these means in {fonvntional form and desi nated by the nfimeral 33. Suitable hand es 34; may be a pliedat any desired points to the wall of t e tub, whereby the tub may be carried about and positioned as desired.

In practical use, the clothinq to be washed is placed in the tub 10 and the cover is closed and latchedin such manner as to hold the agitator in contact. with the clothing. Then the rack 21 is caused to mesh with the pinion 13 and manual force isapplied to the upper end portion of the lever 16 to oscillate sa-icl lever. The lever 16 acts through the pitrnan 23 to oscillate the lever 18, and

the latter lever rectilinearl reciprocates the pit-man 20 and rack 21 to t e rotation of the pinion '13, shaft 12 and agitato The lever 16 acts through the pitman g2 and wrist- ,whecl 31 to the rotation of the spur gear 28,'

vice-to be driven on said support, a hand lever fulerumed on said support, a connecting lever fulcrumed on said support, a-p1ti'nan connecting said levers, a rack connect- 5 ing the latter lever to the device to be' of said support from said hand lever, said levers arranged for oscillation on horizontal parallel axes, a pitman connecting the lower ends of said levers, and a rack connecting the upper end of'the connecting lever and the device to he driven. 20 3. A driving mechanism 'for washing machines, eomprisinga device to be driven, a lever mounted for oscillation, a rack connectiu; said. lever and device to'be driven, a hand :lever mounted opposite the first lever, a pitman'=(au|ueetingsaid levers, a s ured-ineu-asing train of gearing, a balance- \vhcel connected to the terminal gear of the train. and apitmau connectingthe initial gear of the train to the hand-lever.

4. A driving mechanism for washing llltleh'ines, comprising a suitable support, ashaftmounted ilntlte top thereof in a vertical plane, a pinion on the upper end of said shaft, a raek in mesh with said inion, a leveranpuutul vertically on .one Sit e of said HltmmllttlHl hinged at its upper end to said,
