CLOTHES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 327,616, dated October 6, 1885.

Application filed August 20, 1884. Serial No. 141.042.

To all whom it may concern:

Be it known that I, CHARLES K. STINSON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Glothes-Wringers; and I do hereby declare that the same are fully described in the following specification, and illustrated in the accompanying drawings.

This invention is in the nature of an improvement upon that set forth in my Patent N o. 287 ,782, granted October 30, 1883. In my patented machine the frame pieces at each end were pivoted to one member of the clampingl jaws, and the parts were so arranged that both the tub-pressure and the roller-pressure were applied and relaxed by tipping the machine forward and back upon the pivots by which it was attached to its clamps.

In my present improvement the same result is obtained by a similarlnlovement; but instead of pivoting the end frames to the clamps direct I connect one of the clamp -jaws by a terminal ring bearing with the shaft of the lower roller, and I form at the upper extremity of the other jaw, pivoted to the first, a laterally-projecting stud, which engages with a shoulder or recess in the end frame, and thereby I apply both the pressures simultaneously. The lower roller-shaft becomes thus the center of motion, for one clamp-jaw is pivoted upon it, and the upper roller, cross-bar, springs, and end frames move in a curved line, approximately an are, around said shaft in applying or relaxing the pressures.

The action of the parts is more fully explained in the following description, in which subordinate features of my invention are also set forth.

In the drawings, Figures 1 and 2 represent the two jaws of one pair of clamps detached from the machine and from each other. Fig. 3 shows the parts arranged in position for use, the view showing the inner face of the end frame, the roller-journals and cross-bar being in section and the position of the rollers suggested by dotted lines. Fig. 4 is an inside view of one of the end frames, a part broken away. Fig. 5 is an end elevation showing (ModeL) the rolls tipped down, as-when pressure is re- 0 laxed. Fig. 6 is a longitudinal section through the roller-bearings.

A is the shaft of the lower roller, (1, and B that of the upper roller, b.

C O are the end frames, connected trans- 5;

versely by the cross-piece D, by which the clothes are received and delivered from the tub after passing between the rollers.

E E are curved steel springs secured at their lower ends to the end frames and crossbar,

and at their free ends forming bearings e for the journals of the upper rollers.

The two clampjaws F G are pivoted to each other, preferably by a cylindrical stud,

H, formed on the outermost jaw, G, and pro- 6 jecting inwardly through the corresponding aperture, h, in the short jaw F. These studs may be considerably prolonged and enter the ends of a tube placed parallel to the rollers and between the clamps, so as to keep the studs in line axially. Instead of this arrangement, a rigid rod passing loosely through the short jaws may connect the outside clampjaws for the described pivotal movement.

The shorter clamp-j aw, F, has a sleeve or ring 7 5 an outwardly-projecting lug, L, which works in a slot or recess or against a rib or shoulder, K, on the inner face of the end frame. This recess or shoulder is preferably of the cam form, (best shown in Fig. 4,) and is at or near its middle portion considerably higher than 0 at its end it, so that the clamp-jaws will be lifted (or the end frames drawn down) by the tilting movement of the frames upon the journals A, which work in vertical slots in the frame-pieces C, while the lugs L are en- 5 gaged with the recesses or shoulders K. By this engagement of the lug L and shoulder K the springs are put under tension, the rollers The sleeve f 8 are pressed. hard together-{and the pivoted clamp-jaws grasp the edge of the tub tightly whenever the machine is tipped back from the relaxed position of Fig. 5 to the upright working position of Fig. 8, and these pressures are released by the reverse movement of the machinethat is, by again tipping it down toward the center of the tub into the position shown in Fig. 5, in which position it is readily applied to and released from the tub. In these tipping movements the lug L traverses the recess or shoulder K from the end A: most remote to and a little past the center or point of greatest pressure. The two clamp-jaws being pivoted to each other.by the stud H, and being linked to the roller-shaft by the ringf at one end of one jaw, the two'pressures desired are obtained simultaneously by the movement specified. When pressure is relaxed, both rollers drop downward a little,

the journals B of the upper roller resting then upon theupper edges of the frames 0 O, which support it against the spring-pressure, while the lower roller drops slightly farther to be free from pressure.

I claim as my invention 1. In a clothes-wringer, two yielding roll-t ers with suitable springs and two end frames connected by a cross-bar, incombination with clamping devices consisting of two jaws pivoted to each other, one of said jaws having its upper end formed as a ring or strap embracing the journal of the lower roller, while tially as and for the purpose set forth.

3. In combination with the rollers and frame of a clothes-wringer, a clamping device in two parts pivoted to each other, one of the clampjaws having a cylindrical stud cast upon it forming a pivot'for the other jaw, and also having an outward projection cast upon it to engage with a shoulder or recess of the end frame, substantially as set forth.

4. In a clotheswringer, a clamping device consisting of two jaws pivoted to each other, one of said jaws having cast upon its upper end an outwardly-projecting lug, L, in combination with the end framesprovided with the shoulder K, substantially as set forth.

In testimony whereof I hereto affix my signature-in presence of two' witnesses.

CHARLES STINSON.
