WASHING-MACHINE.

SPECIFICATION' forming part of Letters Patent No. 326,903,6lated September 22, 1885.

Application fiel April 11l 1884. (No model.)

To all whom t may concern:

Be it known that I, ELLA GOODWIN, of Chicago, State of Illinois, have invented certain new and useful Improvements in XVashing-Machines, of which the following is a specification.

The invention consists in a washing machine constructed as hereinafter described and claimed.

The accompanying drawings illustrate the invention. Figure l is a central vertical section. Fig. 2 is an open top View, the cover being taken off. Fig. 3 is an enlarged vertical section through a portion of the rubbers.

A designates a cylindrical vessel or tub, which is preferably made slightly tapering from the top to the bottom in theinterior opening. A common wash-tub will answer very well for the cylindrical vessel of a hand-machine.

In the bottom of the vessel is applied the under stationary rubber, B, which is made highest in the center` from which it gradually slopes to the circumference, the form ot' the upper surface being that of a low wide-based cone or conoid.

The upper rubber, C, is concaved on its under side to correspond with the upper convex` surface of the lower one. The rubbers are best made in sections or blocks c in the form of a sector. Their facing surfaces are corrugated, as seen at c c, Fig. 3, the corrugations in each section running about parallel with one ofthe radii.

The upper rubber is attached to a shaft, D, which passes up through the cover E and loosely through the bore ofa pinion, a,which has its hub or sleeve jourualed in a bracket, F, which supports a shaft, a, provided with a crank, G, and pinion a, engaging with pinion a. The shaft D has a long key, a, secured thereto,wl1ich slides in a groove in the bore of the pinion, so that said shaft may rise and fall while remaining subject to the rotary motion of the pinion.

The cover E is hinged together at c, the larger part thereof being free and having the bracket F firmly attached thereto, and the smaller part being secured to. the tub, so that it will supportthe other part when turned back or opened as a lid, thc crank G being first taken off. Vhen so opened, the upper rubber will be lifted out of the tub.

A is a faucet for drawing off the water. The elevated center of the rubbers prevents the clothing while being washed from collecting in a bunch in the center.

The operation is as follows: The crank being taken off, the lid is turned back and the clothes putinto the tub with soap and hot Wa4 ter. rIhe lid is then shut down. This brings thelupper rubber on top of the clothes, and the play of shaft D up and down adapts the upper rubber to the quantity of clothes between the rubbers, and when resting down upon them of its ownweightthe upper rubber is rotated or oscillated back and forth by means of the crank until sufficient rubbing is done and the clothes are cleansed, when they are taken out.

The principle of the rubbers with the elevated center may be applied both to hand and power machines, and the facility with which the rubbers so made and provided with the hinged cover, bracket, &c., may be adapted and applied to .a common wash-tub renders these parts themselves useful and valuable.

My invention does not include machines not having the facing-surfaces of the rubbers made highest at the center and gradually sloping therefrom to the circumference, nor machines with the rubbers whose surfaces are formed of radial wedge-shaped ribs or spokes with open space between the spokes,and havingastandard 01 other obstruction extending through the space between the rubbers, even though such rubbers should be highest in the center, forit is necessary that the surfaces ot' both the rubbers should be continuous, not as open spokes, in order to rub small articles or the edges of larger ones, as the collar and wrist-bands of shirts, sufficiently to cleanse them, and the space between the rubbers at the elevated center should not be obstructed. I do not wish to be understood as claiiningany machine having rubbers with flat facing surfaces; nor any machine with a standard or other obstruction extending through the space between the rubbers at the center, or with one or both of the rubbers made of raised spokes with open spaces between them.

Vhat I claim is- ICO In awashinginachine, the rubbersB C, havported on a shaft, D, terminating in and con- 1o ing their coincident faces composed of a oonnected to the upper side of said rubber, and tinuous surface made highest in the center and supported in a bracket, as F, attached to the gradually sloping therefrom to the cirouniferlid and provided with gearing and a crank for 5 ence,'such surface being laid effin sectors and operating the same, substantially as specified.

provided with corrugations in each sector run- ELLA GOODWIN. ning parallel with one of its radii, said rub- Witnesses: ber B being fitted into the bottom of a tub or J No. H. WHIPPLE,V
