ADDISON W. WALKER, OF ERIE, PENNSYLVANIA.

CLOl'HES- WRINGER SPECIFICATION forming part of Letters Patent No. 547,569, dated October 8, 1895.

Application filed December 19, 1894. Serial No. 532,346. (No modeL) citizen of the United States,'residing at Erie,

in. the county of 'Erie and State of Pennsylvania, have invented certain new and useful Improvements 1n0lothes-Wringersg and I do hereby declare the following to be a full, clear, 'andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i This invention relates to clothes-wringers;

. and it consists in certain improvements in the construction thereof, as will be hereinafterfully described,an d pointed out'in the claim. ,The inventionis illustrated in the accompanying drawings, as follows:

1 Figure I shows a top view'of the wringe'r,

, Fig. 2 shows a side elevation, one of the top cross-pieces being removed and the cam mechanism being in section to better show construction. Fig. 3 is a detail elevation of the cam mechanism, looking from the left of Figs.

AA mark the sides of the frame, the lower ends of which are extended by the curved clamping-fiugersA' A. The upper roll 0 is carried in sliding boxes (not shown) movably mounted in the side pieces, and the lower roll D is journaled by its shaft d in the pivoted clamping-fingers B B and is operated from the crank D. The clamping-fingers B B are pivoted on the curved fingers A A at b and are extended first forward and then downward, and the roll D is carried at the elbow of this finger, so that when a downward pressure ,is exerted on the roll 1.) these fingers B B by reason of their bell-crank shape are operated upon to clamp the wringer to whatever is between the fingers B and A, ordinarily the tub. At the ends of the rolls are guards E E to keep the clothes from the journals. An apron E serves to carry the clothes away from the wringer, and also to connect the lower vends of the side pieces A A, so as to stilfen the frame- A spring F, which rests upon the boxes (not shown) carrying the upper roll, allows an upward movement of the upper roll to accommodate the wringer to the varying thickness of the clothes passing through it. All these parts are common and their construction and operation well known.

It will be noted that thctonsion of the spring F not only regulates the pressure of the rolls, but also exerts the pressure which effects the clamping action of the fingers, so that inadjustingthe spring it must not only be adjusted to regulate the pressure of the rolls, but also to accommodate the clamping-fingers to dilferout thicknesses of tub or striptd'which the 2.

wringer is attached. It is to the Inechanisnr for adjusting and regulating the tension of this spring that my invention particularly relates. a v

. Two top cross-bars G are bolted to the sides of thewringer-frame by means of bolts a. They are each provided with a semicircular sleeve-lug g and a .guideecavity g, so that when together they form a couplet sleeve and guide. In order that the union of the crosspieces may be as rigid as possible, contact;

lugs G are placed on the inside of the crosspieces and a bolt G passed through the sides and the sides clamped together. A screwthreaded sleeve-bolt H is placed in the sleeve formed by the sleeve-lugs g. At the upper end 0t this bolt areformed two cars h, between which is journaled the cam K by means ofthe pin lo,'passed through the. cam and the ears. An internally threaded nutI is screwed on the bolt 11 and operated against the lower ends of the lugs g to draw down the sleevebolt H and the cam. A pressure-bolt J rests on the spring F and passes up through the sleeve-bolt l1 and is ofsuch length as to be operated upon by the cam to tension the spring.

The cam is operated by a cam-handle K, and the cam-surface is of such contour that its point of greatest eccentricity, as k, passes by the top of the pressure-bolt when the handle is fully depressed, so that the handle will remain in the depressed position when once so placed.

It.will be readily seen that the cam always elfects the same movement of the pressure bolt, and after the tension is properly adjusted the cam only will ordinarily be used; but when it is desired to change the tension the cam is loosened and the nut I screwed up or down, as it is desired, respectively, to increase-or diminish the tension, and, again, when the wringer is changed from a tub or strip to one of dilloront thickness and it is desired to retain the same tension the nut I isvoperated in like manner. \Vhen the wriugcr is not in use, the handle thrown. over to the left.

'lhis brings the shortest radine oi the cami'aoe in line with the prcssnre'holt, which allows the measure-bolt to move up and relieve the spring. lhis fiUl'lSilllCiLlOl'l is manifestly :1 strong; one. as there is no tendency to spread orhend the crosiepicces when under severe strain, 'lhe' nrinoipnl advantage, however, of this construction lies in the fact that the can] and adjusting mechanism can he rcmoved by unscrewing the n at I and replaced in n. like manner, so that Where there is any breakage or wear of these parts a new outfit comprising these parts can be supplied from the li-tctor y with the cam properly jonrnaled and emrything in such shape that any unskilled person could place and adjust them in the wrine'er. It also malice the work of a:- l nhiing the parts cheaper and more coniicnt, as the cam mechanism is assembled separately and placed in the frame after its romploliolr It is manifest that the cam and the adjneting mechanism can he used with other styles of wringers than that shown, and hence I do not wish to be limited to the precise style of wringer here shown.

What I claim as new is- In a clothes wringer, the combination, with the \vringcr frame; the rolls; and their eonnectionq; of a screw threaded sleeve bolt placed in said frame; a cam carried by said bolt; a handle foroperating said cam; apressure bolt passing through said sleeve bolt for communicating the cam action to the roll connections; and an adjustingnut on said sleeve bolt for adjusting the position of said cam relatively to the roll connections.

In testimony whereof I ailix my signature in presence of two witnesses.
