llVlPROVED CLOTHESnWRlNGER.

Specification forming part of Letters Patent No. 35,705, dated June 24, 1862.

-in both figures.

My invention has reference to clothes-wringers in which two pressure-rollers, generally made of india-rubber, are employed for wringing;v and it consists, principal1y,in an improved construction and arrangement for securing the proper elastic separation and closing of the rollers.

I employ a simple wooden frame, composed of the upright pieces A A, cross-piece B at the top, and another cross-piece, O, toward the bottom, of suitable dimensions and of any convenient construction. rlhe uprights or posts A A are suitably provided with notches a a, or their equivalents, for attaching to a tub or other support. An inclined board, D, is situated beneath the position of the rollers and over the lower cross-piece, O, all substantially as represented in the drawings.

rlhe rollers E F, of india-rubber'or equivalent material, are secured, in the ordinary manner, to shafts G H, one of which projects from the frame, and is provided with a winch or crank for turning the rollers. The journals of the shafts play vertically in slots b b, of the side frame-pieces, A A, both having thus a free movement up'and down sufficient to allow the rollers to separate as far as ever required. Instead of allowing. only one of these rollers to yield to accommodate the different sizes of articles to be wrung, vI cause both to yield equally and simultaneously, substantially as follows: I employ two springs, M N, generally straight and as long as practicable, in fact, reaching the whole vwidth of the frame and projecting a little at each end. One of them is located on the top of the upper cross piece, B,-of the frame, and the other is secured to the under side of the lower crosspiece, C, the exact location, however, not being essential. They are respectively attached to the cross-pieces at the middle by screws c c, or their equivalents. These springs are of equal or nearly equal strength, and at both ends alike, so that the yielding will be equal at both ends and downward as well as upward. They are as long as practicable, so as to get as little variation of force in their movement as possible, and this result is enhanced by the employment ofthe two springs,

thereby getting a double extent of spring movement with the same variation of elastic pressure.

The pressure is communicated from the springs to the journals of the rollershafts G H by means of sliding bearings P P and Q, Q, arranged in a peculiar manner. They are held in place by a vertical slot in each,

which plays respectively over a screw, f, or

,other end of each bearing is hollowed at g, so

as to :fit against and partly around the shafts G H respectively. These concave surfaces thus not only furnish bearings for the rollershafts, but, on the other hand, the shafts keep the bearings in place, preventing them from turning round out of position.

This construction of the machine is exceedingly simple in all its parts, the wood parts being plane pieces and the met-al portions being either simple castings or of such plane and round forms as to be quickly and easily made and put together. Hence the great objects aimed at-cheapness and simplicity of construction, durability, and efficiency of action-are gained.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination and arrangement of the spring or springs .M N, sliding bearing blocks P l? Q Q, having guide-slots and bearings d d g g, and the stationary guide screws or pins ff, applied to the rollers, substantially as and for the purposes herein specitied.

2. Giving an equal or nearly equal elastic pressure to both rollers simultaneously, by means of the double long springs M N, ar ranged in combination with the slotted frame, substantially as and for the purposes herein set forth.

THOMAS POOL.
