PATENT J AOOB LONGYEAR, OF GRASS LAKE, MICHIGAN, ASSIGNOR OF ONE-HALF HIS RIGHT TO CHARLES EDDY, OF SAME PLACE.

IMPROVEMENT IN WASHlNG-MACHINES.

Specification forming part of Letters Patent No. 175,473, dated March 28, 1876; application filed January 29, 1876.

To all whom it may concern:

Be it known that I, JACOB LONGYEAR, of Grass Lake, in the county of Jackson and State of Michigan, have invented a new and valuable Improvement in Washing-Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and tothe letters and figures of reference marked thereon.

Figures 1 and 2 of the drawings are representations of vertical central sectional views of my washing-machine.

The nature of my invention consists in the construction and arrangement of a washingmachine, as will be hereinafter more fully set forth.

In the annexed drawings, A represents the bed-frame oflny machine, in the center of which is mounted a bevel cog-wheel, B, upon a short vertical axis, at, extending downward from the center thereof. The upper side of the cog-wheel B is provided with pins 1) b, which enter holes in a disk, 0, attached to the under side of the bottom of the tub D, in which'the clothes are to be washed. Within the tub D is a perforated diaphragm, E,supported upon a series of spiralsprings, d d, and upon which diaphragm the clothes are placed to be washed. To the bed-frame A is secured a vertical frame, A, through the upper portion .of which is passed a shaft, G, formed with two cranks, G G, projecting in opposite directions, as shown, and to each crank is, by a strap-hin ge, f, connected a pounder, H. This pounder consists simply of a flat paddle, having a series of vertical bores, 0, extending upward from its lower edge. The

shaft G is rotated by suitable gear-wheels I I, connected to one end thereof, and on the other -ers H H, crank-shaft G, and

end of the shaft is afly-wheel, J, and a pulley, K. The pulley K is, by an endless belt, L, connected with a pulley, M, on a short horizontal shaft, N, in the bed-frame A, and on the inner end of said shaft N is a bevel-pinion, 0, meshing with the bevel cog-wheel B.

By this means the tub D is rotated at the same time as the pounders H are worked up and down, bringing all parts of the clothes under, and subject to the action of, the pounders.

The diaphragm E, resting upon the spiral springs 01, is perforated, as shown, to let the water act on the under side of the clothes at the same time as the pounders act on the upper side. It also gives more room for water, and adjusts itself to a greater or,less amount of clothes with the same force.

I am aware that a rotating tub, 1001' se,is not new broadly and I therefore lay no claim to such invention.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In a washing-machine, the combination of a rotating tub, a perforated yielding diaphragm placed therein, and vertically-reci )roeating pounders working therein, for the purposes herein set forth.

-2. The combination of the tub D, placed on, and rotated by, the cog-wheel B, the perforated diaphragm E, spiral springs d d, pound the gears, belt, and pulleys, as described, and f herein set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
