Application led December 13, 1883. Serial No. 114,476. (No model.)

To aZZ whom t may concern:

Be it known that I, WoR'rHINGToN BULKE- LEY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Clothes-Wringers; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the 'letters of reference marked thereon, making a part of this specification.

My invention relates to clothes-wringers in which pressure-rollers are combined with frame, springs, and adjusting devices to adapt it to general use.

The objects of my invention are, first, to provide a better spring; second, to furnish improved facilities t'or adjusting the pressureon the rollers. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a central vertical sectional view showing the clamp and apron open,ready for use. Fig. 2 is a central vertical sectional view showing the clamp and apron closed, ready for storage. Fig. 3 shows the apron detached from the machine, and Figs. 4 and 5 are end views showing the arrangement of frame, rollers, bearings, and spring, also modications in the swinging clamps, referred to hereinafter. Fig. 6 shows the lower bearing, df, with projection e3, to be used when apron E, with its pivots e2 e2, is removed.

Similar letters refer to similar parts throughout the several views.

The frame A is made in the form of an arch, which sustains the spiral spring B. The lower parts of the frame A are straight and support the rollers D D, bearings d d d d', pins dz d2, folding apron E, and swinging clamps F F. The spring B is made of coiled wire, and conforms to the arch of frame A, thus utilizing the space between the bearings dd of the upper roller, D, and forming a long-arched and easy-acting spring. (See Fig. 2.) The shaft ofthe upper roller D passes freely through vertical slots in the frame A, and rests in the bearings d d', which in turn press the spring B. The pins d2 d2 pass through the frame A, and serve to sustain the upper roller D when the support of the lower'adjusting devices E F F is removed. (See Fig. 2.) The shaft of the lower roller D also passes freely through y vertical slots inthe frame A, and rests in the sliding bearings d d, whichin turn rest on the lower adj usting devices, E F F. -The lower bearings, d d', move vertically in the frame A and rest on the projections e e e e2 of apron E, or, in the absence of said apron,

are formed with projections e3 e3, which shall rest on the swinging clamps F F. (See Fig. 6,

d e3 e3.) The folding apron E has its extremities fitted with pivots e2 e and cams e e. The pivots e'l e2, resting in the frame A or on the swinging clamps F F, allow the cams e e to move freely bythe swinging of the apron into horizontal or vertical positions, for the purpose of adjusting the rollers by their action on the sliding bearings d cl. (See Figs. 1 and 2.) The adjustable swinging clamps F F,hav

ing their outer arms tted with screws ff to secure t-he machine to a tub or support, are arranged to swing horizontally on the frame' A, (see Figs. l and 2,) and are so fitted by means of screw-threads f2 f2 that the swinging of the clamps F F about the frame A causes them to move the bearings d d vertically along the same, and thereby adjust the pressure on the rollers D D. The crank G,

attached to the projecting shaft of the lower roller D,is formed with a socket, g', and fitted with set-screw g2, to secure the sliding arm H so it may be extended, as shown by dotted lines at h', for the purpose of increasing the power of the crank.

In Figs. 4 and 5 I show modifications in the swinging clamps. Fig. 4 shows the body of clamp F formed with the incline f3, and connected to the frame A by means of the pin t'. It is evident the swinging of the clamp will cause it to move vertically along the frame A, press the bearing d', and adjust the rollers D D. In Fig. 5 the incline f* is formed on top of the clamp F, which swings ou the frame A, and is sustained by the shoulder o, the effect in action being the same as i n the preceding.

I also show in Fig. l a modification of the spring B, cutting it in two parts, B B', and inserting the half-nuts c c and taper screw C, for the purpose of further increasing the tension outhe spring, as is obvious from the drawings.

Wringers are ordinarily made with springs, which act independently at each end of the saY IOO

rollers. My spring vill admit of such con-l struction, (see Fig. 1,) but is preferably made continuous, (see Fig. 2,) that it may be free to yield fully from either end in case the strain between the rollers is greater at one end than at the other. n I do not herein claim the combination and arrangement of the folding apron E, as shown and described, as I have made said improvement the subject of separate application for Letters Patent filed March 14,1885, Serial No. 158,883.

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

1. In a Wringer, the combination,with frame,

to this specification in the presence of two sub- 25 scribing witnesses.
