MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,096, dated December 7, 1880.

Application filed December 8, 1879.

To all 'whom it may concern Be it known that 1, CHARLEs H. MILLER, of Erie, in the county of Erie and State of Pennsylvania, have invented a new and useful Improvement in wringing-Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates more particularly to a wringing-machine for domestic purposes,

1o and has for its object to render the machine simple, durable, and compact.

My invention consists or" a wringing-machine having an upper stationary roller and a lower movable roller, which is rendered selfadjusting by means of a spring of peculiar construction arranged between the lower portions of the side frame of the machine; also, of sliding bearings in which the movable roller is supported, and which are provided with exzo tensions having concave ends, which bear against the shaft of the stationary1 roller when the machine is not in use, whereby the rollers are held in such a position as to prevent the spring from exerting any pressure upon the 2 5 contiguous portions of the rollers when not in use; also, of a peculiar construction of the spring whereby the latter is rendered more durable and prevented from being lengthened by compression.

In the accompanying drawings, Figure l is a partly sectional front elevation of my improved wringing-machine. Fig. 2 is a crosssection thereof. Fig. 3 is an end elevation thereof. Fig. 4 is a perspective view of one of the bearings of the movable roller.

Like letters of reference designate like parts in the several figures.

A A represent the side frames of the machine, which are securely connected by a tierod, b, and the inclined plate or table c. D

represents the upper stationary roller turning in fixed bearings formed in the upper ends of the side frames, A A. E is thelower movable roller, having its shaft f supported in sliding 4 5 bearings G G, arrangedin recesses or depressions g on the inner sides of the side frames, A A. H is an upward extension formed with each bearing G, and made of such length that the upper end of the extension H will come 5o in contact with the shaft of the upper stationary roller and arrest the upward movement of the lower movable roller when the two rollers are about in contact with each other. t' are vertical slots formed in the side frames, A A, to permit the vertical movement of the shaft of the lower roller, E. is 7c are two lugs formed on the lower end of each bearing G, so as to form a recess or socket for the reception ofthe ends of the upper bar of the spring L.- The latter is composed of two flat bars bent so as to converge from their distended ends toward the middle.

Each bar is bent back or indented at the middle,so as to form two convex bearing-surfaces, m m, by which the two bars come in contact with each other. The ends of the lower spring-bar rest upon the bottom of the recesses g of the side frames, and the ends of the upper bar rest against the lower ends of the bearings G, between the lugs k thereof.

When the machine is not in use the extensions H of the bearingsl G rest against the shaft of the upper roller, D, and prevent the spring from pressing the lower roller against the upper roller, thereby avoiding the Hattening of the rollers, which always takes place to a greater or less extent when this pressure is not relieved.

Upon introducing the garments or other articles between the rollers the latter are forced apart and the distended ends of the spring L are compressed. As the distended ends of the springs approach each other the central bent portions of the spring-bars are distended, thereby avoiding the lengthening ofthe springs by compression, which takes place in ordinary springs. This peculiar construction of the springs renders the same also more powerful and more durable, thereby rendering an adjustin g device unnecessary and permitting the spring to be located between the lower portions of the side frames, which portions form one of the jaws by which the machine is secured to a tub or other vessel or support.

I claim as my inventionl. In a wringingmachine, the combination, with the side frames, A A, of the upper roller, D, supported in fixed bearings, the lower roller, E, supported in movable bearings G, and the spring L, constructed with convex bearin g roo surfaces m, and having its distended endsI arranged in the recesses g of the side frames, below the lower roller, substantially as set forth.

2. In awringing-inachine, the combination, with the side frames, A A, provided with recesses g, fixed roller D, and movable roller E, of the sliding bearings G, provided with eXtensions H, having concave ends adapted to come in contact with the shaft of the fixed roller before the surfaces of the two rollers touch each other, thereby preventing the rollers from being pressed against each other when the machine is not being used, and avoiding the flattening of the rollers, substantially as 4set forth. V

3. The spring L, composed of two at bars having distended ends, and having their middle portions bent back or indented to form two convex bearing-surfaces, m m, by which the two bars bear upon each other, substantially 2o' as set forth.
