CLOTH ES-WRING ER.

SPECIFICATION forming part of Letters Patent No. 229,129, dated June 22, 1880.

Application filed May 4, 1880. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN HERSHEY, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Glothes-Wringers, of which the following is a specification.

This invention relates to certain improvements in olothes-wringers; and it has for its object to provide a uniform pressure upon the body of the clothes as the thickness of the same may be varied, whereby the danger of bending the roller-shaft and loosening the rolls is to a great extent overcome, and the necessity of adjusting the pressure-springs to regulate the pressure of the rollers is obviated.

To this end my invention consists, first, in the combination, with end standards provided with friction -rollers journaled thereon, and with a lower wringer-roll having its end bearings arranged on said friction-rollers, of horizontally-projecting lever-arms pivoted at one end to the said standards, the friction-rollers on which the end bearings of the upper wringerroll are arranged, and links connecting the free ends of the lever-arms with the bent ends of a torsion-spring extending longitudinally along the wringer-frame, as will be more fully hereinafter described; second, in the combination, with the standards of a clothes-wringer and the lower roller thereof, jonrnaled in fixed bearings, of an upper roller journaled at each end between friction-rollers journaled at the upper ends of the respective standards, and similar friction-rollers journaled in levers pivstandards, the said levers being connected at their outer ends to a suitable spring by means of links, whereby a uniform pressure may be made to bear upon the rollers irrespective of the thickness of the body of clothes passed between the rollers, as more fully hereinafter specified.

In the drawings, Figure 1 represents a front elevation of my improved wringer with the parts in a normal position; Fig. 2, a rear elevation, showing the wringer attached to the edge of a tub. Fig. 3 represents a side elevation, showing my improvement; and Fig. 4, a

side elevation, showing a modification thereof.

The letterA indicates the base of the wri n ger, 5 o

and B B two angular standards mounted upon said base. The said standards are formed with parallel vertical walls I) b, between which are journaled the friction-rollers G D E, the rollers O D being journaled in the lower horizontal portion of the standards, and forming fixed bearings for the journals of the lower roller and the roller E at the upper part of said standards.

- The letter Findicates two levers pivoted to the upper part of the respective standards, and carrying the friction-rollers G. The outer ends of the levers F are connected, by means of the links. H, to a spring, I, adjustably secured to the base A of the \vringer. 6 5

The letters K and L indicate the respective rollers, the journals of the lower one resting upon the frictionrollersG I). The up'perroller, in anormal position, rests upon thelower roller,

L, audits journals have their bearings against the friction-rollers E G, below the bearings of said rollers in thelevers F, and below the fulcrnms M of said levers, the outer ends of said levers, to which the connecting-links H are attached, extending above thejournals of the 7 5 upper roller, for the purpose hereinafter specified.

The spring I is provided with an'arm, i, Fig.

1, having a loop or eye, which engages an annular recess. at the'end of an adj nstin g-screw, N, passing through the base of the \vringer, by means of which the tension of the spring may be regulated.

In the modification shown in Fig. 4 of the drawings, instead of two friction-rollers being employed to form the bearings for the journal of each roller of the wringer, a series of such friction-rollers are employed extending entirely around thejournal, thejournals of the i'rictioir rollers in this case being confined in circular o apertures in the standards and the levers, respectively.

The operation of my invention is as follows: Upon passing a body of clothes between the rollers they will be forced apart necessarily. The lower roller, having its shaft journaled in fixed bearings, cannot move; consequently the upper roller will be compelled to yield. The

upper one in yielding has to follow the curve described by the friction-roller E, as it moves with the pivoted lever. As the roller is raised the lever approaches the central vertical line of its fulcrum, (indicated by y y, Fig. 3,) carrying the friction-roller E with it. Now, as the outer end of the lever approaches the central vertical line the leverage is diminished, and vice versa, so that as the tension of the spring is increased as a thicker body of clothes is passed between the rollers the leverage is diminished, so as to provide a uniform pressure upon the rollers irrespective of t the thickness of the body of clothes passing between them.

The wringer attachment may be connected with a wash-tub in any suitable manner; but in the present instance the devices for supporting the wringer on the edge of a wash-tub consist of two pins, 0 0, extending from the base of the wringer, and a clamping-bar, P, to the center of which is pivoted one end. of a pivoted lever, Q. The pins 0 rest against the outside of the tub, and the bar P is clamped against the inside of the tub by merely swinging the lever on its fulcrum. What I claim, and desire to secure by Letters Patent, is-

1. The combination, with the standards B,

. provided with friction-rollers journaled thereon, and the lower wringer-roll, L, having its end bearings arranged on said friction-rollers. of the horizontally-projectin g levers F, pivoted at one end to the standards, the friction-rollers on which the end bearin gs of the upper wringerroll are arranged, the links H, attached to the outer free ends of the said levers, and the tor-v sion spring I, extending along the wringerframe and having its bent ends connected with the lower ends of the links, all substantially as and for the purpose described.

2. In combination with the standards of a clothes-wringer and the lower roller thereof, journaled in fixed bearings, an upper roller journaled at each end between friction-rollers journaled at the upper ends of the respective standards, and similar friction-rollers in the levers pivoted to the said standards, the said levers being connected at their outer ends to a suitable spring by means of links, whereby a uniform pressure may be maintained upon the rollers irrespective of the thickness of the body of clothes passed between them, substantially as and for the purposes specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

BENJAMIN HERSHEY.
