Letters Patent No. 75,231, dated March 3, 1868.

IMPROVED CLOTHES-WRINGBR.

To ALL WHOM 1r MAY eoNeERN;

Bc it known that I, GEORGE L. WITSIL, of Philadelphia, in the county of Philadelphia., and Stateef Pennsylvania, have invented a new and useful Improvement in Wx'inging-B'Iachincs; and I do herebydcclare that` the following is n. full, clear, and exact description of the saine, reference being had to the anncxeddrawings, making part of this specification, in which- Y Figure 1 is a perspective view, and

Figure 2 is a side elevation of the shaft of the rollers.

The same letters are employed in all the iiguresin the designation of the same parts.

Myimprovements relate to machines for wringing clothes by passing them between elastic rollers, by the compression of which the water is forced from the clothes; and they consist in attaching the elastic facing of the rollers to roughencd shafts, so as to prevent the coating from turning on lthe shaft, and, secondly, in tho form and arrangement of the springs by which an equa-l pressure is maintained upon theclothes subjected to the action of the rollers. 1

The following description will enable persons skilled in the art to manufacture my improved machine:

The wringcr is attached to a cast-iron`frame forming jaws, by which it may be secured to the edge of a. \`vash-tnb. The parts of the frame A A are straight, and intended to sct on the inside of the tub, the semicireularpieee A' extending over the outside of the tub, and being secured in place by the set-screws B. The endpicces C C of the 'frame to which the jaws are attached form bearings for the journal of the lower and stationary roller, D. ,f 'lhe upper roller, D, rests upon the lower roller, D', and its journals have their bearings on the under side ofthe springs E E. The springs are made of steel, bent inte the form shown in the drawings. The ends ofthe strips of steel forming the springs arefnstencd to the sides ofthe frame C C. lThey are bent upwards in the middle of the upper part, to form semicircular recesses to receive the journals of the upper rollers. The springs, while they permit the upper roller to yield to the irregular thickness of the clothes suh- `jccted to their action, maintain a constant pressure. The lower roller is turned by a winch, F, attached to the extension of its axle. The roller is formed by a. metallic shaft, G, around which an elastic facing of India rubber is cast. In order that this facing may not turn upon the shaft, the latter is formed with projections from its face, as shown in tig. 2. V i

What I claim as my invent-ion, and desire to secure by Letters Patent, is-

Thc`combination of a fixed roller, D', yielding upper roller D, and springs E, when the latter are formed as set forth, and attached to the frame at both ends, so as to give them staunchness to resist lateral pressure, and also so constructed as to form bearings for the upper roller, by being bent into the shape substantially as set forth.

In testimony whereof, I have signed my name to this specification in thc presence of two subscribing witnesses GEO. L. WITSIL.,
