SPECIFICATION forming part of Letters Patent No. 699,766, dated May 13, 1902. Application filed August 26, 1901. Serial No. 73,386. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. ROBINSON, a citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in iVashing-lvlachines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference generally to washing=machines; and it consists in the novel construction of a machine of this type and in the peculiar arrangement and combination of the various parts thereof, as more fully hereinafter set forth.

In the drawings illustrating my invention, Figure l is a perspective view of the washingmachine. Fig. 2 is a vertical central section through the machine; and Fig. 3 is a sectional view of a portion of the machine, illustrating the construction of the springbacked packing for the guides.

In the drawings thus brieiiy described the reference-letter A designates a supportingframe having a laterally-extendin g overhanging section I3, as shown. Mounted within this framework and suitably secured thereto is a suds-receptacle C, the main portion ofwhich is substantially cylindrical in form. I'Vithin the receptacle and occupying the lower half thereof is a rubbing-surface D.

E designates a cross-bar forming a part of the framework A, upon which are mounted at each end thereof standards F, provided at their upper ends with tubular bearings G. Journaled within the bearings described is a drive-shaft II, which is bent to form angularly-extending cranks I and carries at one end a drive-wheel J.

K designates plunger rods extending through the cross-bar E of the framework and carrying at their lower ends pounders L, as plainly shown in Fig. 2. These pounders are preferably conical in configuration and are provided with a transverse apertured diaphragm M midway between the apex and base. The lower end of each rod extends within its respective pounder, and the extreme end portion of the rod projects through the diaphragm, as indicated, the latter forming a brace for the rod which gives rigidity to the pounder. The pounder-rods extend through rectangular openings u, formed in the crossbar E, and are provided each with a stationary packing Z) for the rear edge and a springbacked packing c for the forward edge or side of the rod. The latter packings are carried by blocks O, which tit Within recessesV P, formed in the outer edge of the cross-bar, and are connected to the cross-bar by bolts Q, extending through said cross bar and clamped thereto by suitable nuts R. The springepacking, las shown, is adapted to fit within a recess CZ, formed in the inner edge of each block, and arranged intermediate the rear portion of the packing and in the rear wall of the recess is a coiled spring e, which serves to keep the packing constantly in contact with the plunger-rod, and thus take up the wear of the latter. The upper ends of the plunger-rods are connected to their respective cranks upon the shaft II by means of springs S, each spring laterally curved in the form of a gooseneck, as plainly shown in the drawings. The upper end of each spring is sleeved over the central portion of the crank, while the lower spring end extends within a slot formed in the top portion of the pounder-bar and is retained therein by suitL able bolts or screws f.

It will be obvious from the description of the machine as thu's set forth that upon rotating the drive-shaft through the agency of the hand-wheel .I an elliptical movement will be imparted to the pounders, and the latter will be caused to effectively act upon all of the clothes in the sinds-receptacle. The springs intermediate the pounder-rods and the shaft admit of a yielding pressure upon the clothes. Thus the wear and tear on the clothes is reduced, and the jar of the machine caused by the pounder striking the clothes is obviated. It is to be further noticed that the type of spring employed intermediate the pounderrods and shaft is simple in construction, effective in operation, and may be rigidly secured to the parts to be connected. Also in view of the simplicity of the spring employed there are no parts to get out of order and to require adjustment.

Vhat I claim as my invention is- In a washing-machine, the combination with the slide-receptacle, of a drive-shaft journaled in bearings above said receptacle,

cranks upon the shaft arranged in angular In testimony whereof I affix my signature elgion to deach ther fo 1ghehpurpose set in presence of two Witnesses.
