UNITED STATES PATENT OEEICE.,

M. HARRISAND R. G. BUSH, OF JAMESTOWN, NE/V YORK.

WRINGING-IVIACHINE.

Specification forming part of Letters Patent No. 48,933, dated July 25, 1865.

To all 'whom t may concern Be it known that we, M. HARRIS and R. G. BUSH, of Jamestown, in the county ot' Chautauqua and State of' New York, have invented certain new and useful Improvements in Machines for Wringing Clothing; and we do hereby declare that the following is a full, clear,

- and exact description of the same, reference in slide-blocks O, as is customary, and saidV slide-blocks are pressed down by means of the har E and thumb-screw g, in order. to tighten the pressure upon the clothing or adjust the The shafts l and J are made of metal and tluted, as shown in Figs. 3 and 4, in order to hold the rubber covering securely upon them and prevent its turning, land they are also galvanized to prevent corrosion.

It will be observed that the shafts J and I are made longer at one end and project beyond the frame, and are so constructed that the handle which is applied to one can be applied to both, and that the handle is so constructed as to admit ot its being applied to both, and so that it will revolve when applied to either.

The great advantage of this arrangement is to prevent the wear upon one roller more than upon the other. Itis a well-established factin this class ot' wriaging-machines that when the upper roller is turned or rotated by the friction of the lower roller it will beconlein a short time completely destroyed, while the upper roller remains almost as good as new. To overcome this del'eet and make both ot' the rollers wear alike, and also to prevent the rubber from turning by wear upon the shal't, the shafts are extended and so constructed as to allow ot the handle being applied to either, and thus equalize the wear.

Krepresentsa bar, which is secured by means ot' a thumb-screw, a., to the frame A, and is used for the purpose of securing the frame to a tub or vessel in which the clothes are washed. This bar K is operated by means ot' a roller, L, which is provided with cams near its ends, which work in openings between the i'rame A and bar K. f V

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-,

The arrangement et rubber rollers upon shafts which have their ends extended, and constructed so that handles can be applied to each or both when said rollers and shaft-s are used in a frame for the purpose of wringing clothing, as is herein t'ully set forth.
