` UNITED STATES JAMES R. RICE, OF

WASHING Application led May 2,

To all whom t may concern:

Be it known that I, JAMES R. RICE, a citizen of the United States, residing at Elkhart, in the county of Morton and State of Kansas, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification.

The present invention relates to washing machines for clothes and the like, and has for its principal object to provide a structure embodying a rotary drum, and means at the end thereof for causing the water and steam, to move to and fro in the drum, as the same is rotating.

Another important object of the invention is to provide a rotar drum having cylindrical extensions with pistons mounted thereon which will be reciprocated in unison, simultaneously with the rotation of the 1J drum.

A still further object of the invention is to provide a washing machine of this nature, which is exceedingly simple in its construction, strong, durable, and one which is efficient and reliable in its operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in View, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

Inthe drawing, the ligure is a side elevation of the washing machine, embodying the features of my invention, showing portions in section.

Referring to the drawing in detail, it will be seen that 1 designates a rectangular frame, including the top and bottom longitudinal members 2 and 3 respectively, and the end transverse members 4 and 5, which extend vertically while the longitudinal members 2 and 3 extend horizontally. Cross members 6 and 7 extend between the members 2 and 3, parallel and spaced from the end members 4 and 5. A drum S is preferably constructed of two hingedly associated sections, one forming a body, and the other a closure,.and has foraminous partitions 9 therein, between lwhich the clothes may be loosely placed. There may be any desired number of the partitions 9. Conieal extensions 10 are formed on the ends of the PATENT OFFICE.

drum 8 and terminate in cylinders 11. The drum 8, extensions 10, and cylinders 11 are all axially aligned. The ends of the cylinders 10 are journaled as at 12, in the cross members 6 and 7, and rods 13 extend into the cylinders and have fixed on their inner ends pistons or plungers 14. These rods 13 are slidable through bearings 15 provided on the ends 4 and 5. To the ends ofthe rods 13 there are attached depending bars 16, attached to rods 17 The rods 17 are slidable through bearings 18 on ends 4 and 5, and bearings 19 on cross members 6 and 7. Connecting rods 2O are pivotally engaged with the ends of the rods 17. A shaft 21 is journaled on the auxiliary frame 22 and also on the longitudinal member 3 of the frame 1. At the bottom end of this shaft 21 there is mounted a pulley 23. On the upper end of the shaft 21 there is fixed a disc 24 having a wrist pin extending eccentrically therefrom and also connected to a bevelled gear 25 journaled in the bracket 2G extending from the cross member 7. The connecting rods 20 have their inner ends pivoted to the wrist pin 24 between the disc 24 and the bevelled gear 25. A bevelled gear 27 is formed on the drum 8 and meshes with the bevelled gear 25.

The pulley 23 is rotated from any suitable prime mover for imparting rotary motion to the shaft 21, thereby causing the rotation of the disc 24, gear 25, and drum 8, through the gear 27. The wrist pin between the disc 24 and gear 25 will cause the reciprocation of rods 17 and 13 and also the reciprocation of the pistons or plungers 14 in the cylinders 1l. It will thus be seen that as the drum 8 with the clothes therein is rotating the water and steam will be agitated to and fro in the cylinder, so as to pass through the clothes and remove the dirt therefrom.

It is though that the construction, operation, and advantages of the invention will now be clearly understood without a more detailed description thereof. `The present embodiment of the invention has been disclosed merely by way of example, and it is apparent that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

VHaving thus described my invention, what I claim asrneW 1s: Y

In a Washing machine of the class described, a frame, a drum rotatably mountedYV in the frame and provided with axial end extensions in the forni of cylinders, plungers slidable in the cylinders, a gear formed on the drum, a second gear meshing therewith, a pin extending eccentrically from the gear',

1,5esg240 connecting rods pivoted thereto, means for l0 connecting the connecting rods with the plungers, and ineans for Operating the second gear thereby causing` simultaneous rotation of the drinn and reciprocation of the plnngers. I In testimony whereof I aliix my signature.

JAMES R. RICE.
