IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent BIO-138,379, dated April 29, 1873; application filed March 21, 1873.

To all whom it may concern:

Be it known that I. GEORGE J. COLBY, of Iteadin g, in the county of Hillsdale and in the State of Michigan, have invented certain new and useful Improvements in Washing Machines; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked to which my invention appertains to make and use the same, I will 'now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure 1 is a perspective view, and Fig. 2 a side elevation, partly in section, of my machine.

A A represent the end pieces of the frame, connected near their lower ends by a board, B, and a suitable distance above the same by a round, 0. Near the upper end of one of the end pieces A is a short vertical slot for the insertion of one journal of the large roller D, while in the upper end of the other end piece is a slot into which the crank E drops, the inner end of said crank forming the other journal of the roller D. Upon this latter end piece is pivoted a button, G, the ends of which form hooks, as shown in Fig. 2, to fasten over the inner end of the crank E, thereby holding the upper or large roller in its position. HH rep resent the smaller rollers, which form the roller-bed. The journals or .gudgeons a of the rollers H are placed in inclined slots b in. the end pieces A, and supported upon springs (1. These springs are placed in holes f made in the end pieces A, and held in the same by pins e, or other suitable means.

The rollers H H, whatever their number may be, are thus allowed to act independentof each other, which I consider the most essential feature in this class of machines to form a successful washer. Any number of rollers may be used, and they may be either smooth, fluted, or corrugated.

The machine thus constructed is fastened to the wash-tub bythe following means: A halfround 'cleat, I, is fastened on the bottom of the tub, and the lower ends of the end pieces A A are cutout to fit over the'same. A screw, J, is then passed through the board B into said cleat I, thereby holding the machine in place. By unscrewing the thumb-screw J from the cleat the machine can at once be lifted out of the tub.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of the frame A B O, crankroller D, smaller independently-operating rollers H, button-hook G,-cleat I, and thumbscrew J, all constructed and arranged substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 11th day of March, 1873.
