To all 'lUhODt/tt may concern:

Be it known that I, FRANK EvANs THOMP- SON, a citizen of the United States, residing at Newton, in the county of J asperand State of Iowa, have invented a" new and useful Gearing for Washing-Machines, of which the following is a s ecification.

The object o my invention is to rovide a washing machine of simple, durab e and inexpensive construction, so arranged that the operative mechanism thereof may be readily attached to, or detached from the machine when desired bythe user. Further, to provide an operating mechanism constructed as an independentunit, and not ca able of being thrown out of alinement shou d the parts of the machine, which come in contact with water, warp. Furthermore the user of my machine may stand erect while operating it,

should he desire, and all the working parts ofthe machine are readily accessible for cleaning and oiling.

My invention consists in the construction of an operative mechanism of a washing machine assembled as a unit, readily attached and detached from the tub portion of the machine, means for attaching said mechanism to the tub and means for transmitting the working power to the agitator within the tub, as hereinafter more fully set forth,

pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a washing machine embodying my invention. Fig. 2 is a side view of the operating mechanism attached to the. tub portion of the washing machine. Fig. 3 is a plan view of the device. Fig. 4 is an end view of the driving shaft, the Fig. 5 is a detail perspective view of one of the suppor'ting eyes upon which. the operating mechanism is mounted. Fig.6 is a detail View showing one of the spokes of the large sprocket wheel with which the operating lever is connected. Fig. 7 is a side. elevation of awashing machine vembodying a modified form of my invention. Fig.8 is an end elevation of the operative mechanism attached to one of thesup orting legs of the stand, showing the stand t own upwardly, bringing the parts into 'a'com act position. Fig. 9 is aside elevation oft e device as shown in Fig. 8.

Referring to the. accompanying drawings,

the numeral 10 indicates the tub portion of.

the washing machine; th e swinging ortion of the top is indicated by 11, attac ed by hinges 12, to the fixed portion ofthe cover 13. I have provided an agitator, comprising the head, 14 and the shaft 15, which passes through the journal plate, 1.6, and is su portedand driven by a pinion 17. Attac ed to the side-of the tub 10, near its upper portion are two eyes, 18; and beneath these eyes are the eyes, 20. I have provided a gearing supporting frame, 21-, having attached to it two pairs of sup orting hooks, 22 and '23, adapted to enter t -.e supporting eyes 18- and 20, all

of which are designed to maintain the operating mechanism of my device in position relative to the tub. Secured to the "u )per portion of the frame 21, above the hoo s 23, is a supporting bracket 24, adapted to rest upon the fixed portion of'the cover 13, the ends 25 of the supporting bracket 24 bein bent up ward at substantially right-ang es to its body portion. In the end 25, there is a j ournal '26, through which passes the driving shaft 27 upon which is mounted the sprocket wheel 28. v

Mounted upon the stub shaft 29, near the :lower end of the frame 21, is the balance.

wheel 30 The small sprocket 31 is formed 4 integral with the hub of the balance wheel 30 and a sprocket chain. 32 passes around the

sprockets

28 and 31. Attached to the central portion of frame 21 is the bracket 33 to which is pivoted the operating leverF-S i, plvotally attached to the central portion of which at one end and at its other'end to a pinion 17 and. held in operative position by the angular extension of the plate 16; ex-

tending throu h the outer end of the rackbar 38, is a bdlt 39 securingit to the guide block 40, which is fitted to reciprocate in. a channel in the extension, 40 which forms a part of the.' supporting bracket 24, this angular extension 40 bein substantially parallel with the driving s aft 27. Mounted on the outer end of the bolt 39 is a roller 41,

fitted to engage'a suitable cam 42,-which is; I

rigidly attached to the driving shaft. 27 so that as the shaft 27 i t'rotated the cam will 3 cause the rack 38 to reciprocate and impart a rotary reciprocatory motion to the agitator in the tub. Secured to the sprocket 28, is a handle 43, which may be used in operating the machine in place of theoperating lever 34 and thevpitman 35 which parts may be detached if desired to operate the machine by using the handle 43.

In the practical use of my invention'the operator applies power to the operating lever 34 or the handle 43, which causes the large and small sprockets and balance wheel to revolve, communicating a rotary motion to the driving shaft 27. volves, the cam 42 engages the roller 41 and causes the rack bar 38 to reciprocate, thus communicating a rotary reciprocntory motionto the agitator within the tub, the balance wheel 30 by its rapid movement creating a steady action of the machine. When itvis desired to move the machine, the operator may remove the operating mechanism for the purpose of dividing the weight of the device.

In a modified form of my construction shown in Figs. 7, 8, and 9, the tub 10 is detachably mounted upon the stand .48 by means of the clamps 44. To add to the stability of the construction I have provided two connecting

bars

49 and 49*, rigidly attached to the legs 45, substantially as shown in Fig. 9. I have also provided the braces 50 pivoted to the stand 43 and adapted to engage the eyes 51, which are firmly attached to the

bars

49 and 49 near the middle portion's thereof. On bars 52 firmly joined to the set of legs 45 which is connected by the bar 49, and upon said bar 49, I mount rigidly the gearing supporting frame 21. In the use of this form of my device, if desired to move the machine, the operator may readily release the clamps 44 and remove the tub 10. By disengaging the braces 50 from the eyes 51 the stand 43 may be raised upon the pivoted supporting legs to which the frame 21is attached and the other legs Willswing down war'dly so that the entire device assumes the position shown in Fig. 8, the shaft 27 and parts mounted thereon extending through the opening 58 in the stand 43 and the rack 38 folding upwardly as shown- In this way the operating mechanism and tub'supporting frame may be brought into close compass for transportation and ease in handling As this shaft re-- Having thus described my inv ention, what I claim and desire to secure by Letters Patent of the United States therefor, is

1. In a device of the class described, the combination of a support, supporting frame arranged at one side of and detachably connected with said support, a rotary element mounted in the support, a rcciprocatory bar mounted on the supporting frame and operatively connected with said. rotary element, a drive shaft mounted on the supporting frame and removable with it, a cam :hxcd on said shaft and in engagement with the recip rocatory bar for operating the bar during the rotation of the shaft, a balance wheel mounted on the supporting frame, and, a speed increasing gearing device connecting the drive shaft with said balance wheel.

2. In a device of the class described, 4: support, a supporting frame dctachably connected to one side of the support and having a bearing and guide overhanging the sup port, a rotary element mounted in the support, a reciprocatory bar connected. with said guide, and having it lateral projection, said bar being oporativcly connected. with said rotary element, a drive shaft mounted in the bearing of the supporting frame, a cam fixed on said shaft and in engagement with the projection on the reciprocatory bar, a balance wheel mounted p11 thelower portion of the supporting frame, and a speed increasing gearing device for operating said balance wheel by power from the drive shaft.

3. In a device of the class described, the combination of a support, a rotary clement mounted in the support, a supporting frame detachably mounter, on one side of the support, a drive shaft mounted on the support, means operated by the drive shaft for imparting an alternating rotary motion to the rotary element when the drive shaft is rotated -in one direction, a balance wheel mounted on the lower portion of the support, and a gearing device operatively connecting the drive shaft and the balance wheel, and means for rotating the drive shaft.
