Letters Patent No. 114,231, dated April 25, 1871.

IMPROVEMENT IN CLOTHES-WRINGER S.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that 1, WILLIAM H. Townes, of Boston, in the county of Sulfolk and State of Massachusetts, have made a new and useful Improvement in Olothes-Wringers; and I hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawing which forms a part of this specification, and in which- Figure 1 is a perspective, and

Figure 2 a vertical cross-section.

The main parts, shown in the drawing, are the same as now in common use. The frame, the rolls, the crank, and general arrangement of parts, being the same as now used and well known,need not be particularly described.

My invention relates to devices for rendering the rolls self-adjusting both at their ends and also throughonttheir entire lengththat is, I employ three springs, one placed over the middle of a cross-bar, and the others placed one under each end of the same cross bar, and resting on the movable bearings which carry-- the ends of the upper roll. This arrangement makes the distance between the rolls self-adj usting, and gives a wider play than in the ordinary plan, where it is common to have a set-screw or other device instead of the middle spring, as in my plan.

The following description will enable others to make and use my invention.

1n the drawing- A A are the side pieces of the frame, connected by upper and lower cross-bars B B.

The lower or stationary roll C and the upper or movable roll .1) arem'ounted in bearings placed in a groove or recess in the side pieces A A in the usual manner.

On top of the bearing-blocks d d, which carry the roll D, are rubber springs ff.

On top of the springs ff is a cross-bar, G.

Between the middle of the cross-bar G and the upper cross-bar ot the frame is a spring, 9, fixed in a bar, B, and'kept in position by the spindle h.

This spring 9 is bound with wire bands it i, as shown, soas to give it greater strength.

The clamps are made of a movable jaw, K, in the upper end of which is a hole to move over the guidepin on, which is fixed in the upright A.

The jaw K is fastened to the upright by screw P, which binds it to the upright A, and thus clamps the machine to the side of the tub or washing-machine. The screw P is provided with a large head, so as to give greater force in turning it.

By this arrangement the jaw K moves to and from the upright A always parallel to itself. It clamps the side of the tub throughout its contact with the same force. When jaw K is hinged or attached by a swivel, as heretofore, itbites the side of the tub hardest at the upper edge, and socrushes or bruises it.

I Having thus described my invention,

What Lclaim, and desire to secure by Letters Patent of the United States, is---- The combination of the springs ff, cross-bar G, spring g, and cross-piece B, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

M. H. TOWERS.
