CLOTH ES-WRINGER.

SPECIFICATION forming part of- Letters Patent No. 434,303, dated August 12, 1890.

Application filed December 10, 1889. Serial No. 333,236. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES K. STINSON, a

' citizen of the United States, residing at Bossuch as will enable others skilledin the art to which it appertains to make and use the same.

My present invention relates to an improvement in clothes-wringers, the object of the invention being to improve the construction and operation of machinery of this class and provide a simple, cheap, and durable wringer for domestic and laundry use; and the invention consists in the construction, arrangement, and combination of parts, substantially as will be hereinafter described and fully claimed.

In the accompanying drawings, illustrating the invention,Figure 1 is an end View of my improved elothes-wringer. Fig. 2 is a vertical sectional inner end view on the line 00 0c of Fig. 3. Fig. 3 is a side elevation in partial section. Fig. 4 is a detail perspective view of one of the cam-provided ends of the clothes board casting. Fig. 5 is a perspective view of one of the roller-supporting jaws. Fig. 6 represents a sideview and an edge view of the parts shown in Fig. 4. Fig. 7 is a detail plan View of the clothes-board.

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

This wringer has the usual pair of squeezerollers, A denoting the upper roller, having journals a a, and B denoting the lower roller, having journals 1) b, said rollers being of suitable and convenient length and diameter, as well as material, such as gutta-percha, rubber, or other substance.

The main frame of my improved wringer consists, essentially, of two upright end castings C C, suitably shaped and formed to permit the arrangement therewith of the several mechanical elements comprising the machine. The journals a a of the upper roller A are located in bearings c c, situated within the lower ends of the vertically-elongated boxes, niches, or casings C C, formed integral with and as a part of the end castings C C, within which end.

necting-bar or arch D, which assists in keep-,

ing the ends of the main frame in place. The

journal-bearings c c are each provided on the outer side with an upwardly-projecting pin, spindle, or extension 0, which passes through an opening in the connecting-bar D near its (See Figs. 1 and These lateral pins lie alongside of the rubber springs and enter the connectingbar loosely. They serve to better unite the parts of the wringer together, and thus make it stronger. They help to keep the rubber springs in place and are found useful in perfecting the arrangement of the upper portion of the wringer.

My present wringer, as is customary with machines of this class, is intended to be clamped or secured to the tub or other receptacle with which it is used by means of suitable jaws. jaws adapted to be on the outside of the tubare cast integral with the end portions C C of the frame, and hence are rigid and stationary. The inner jaws F F are movably'hung, and they support the lower roller B. One of these jaws is shown in perspective in Fig. 5'. The leg'or jaw proper F has a tail or extension F, which is substantially at right angles to'the partF, so that the casting of the said jaw may be said, irrespective of its particular contour, to be of a general right-angled form. Its vertex is provided with an integral j ournal-box f, projecting horizontally on each side of the main casting of the jaw and long enough to provide a sufficient bearing for the journal I) belonging to the lower roller B.

The outer jaws E E-that is, the

Said journal-boxes f f project through slots opening g, of any desired size and shape, to

receive the crescent-shaped cam I on the ends of the clothes-board casting and likewise to permitthe passage therethrough of the tie-rod on which these inner roller-supporting jaws adapted to receive the edges of board G.

The extreme ends of the rim K are preferably enlarged to a greater or less degree in a circular or other convenient shape h, thus presenting a vertical side or plate-like portion.

Each of said enlarged ends of the clothesboard casting is perforated with a circular opening 1', (see Figs. at and 6,) and through these circular openings passes the horizontal tie-rod H, which also runs through the openings g g in the tails of the inner jaws, and, furthermore, has its ends projected through the castings O (J, wherein the rod is supported and which it serves to tie together, the said projecting ends of the tie-rod being furnished with nuts that are screwed up tightly against the outside faces of castings O O, as shown in Fig. 1. The said enlarged ends of the clothes-board casting, in addition to being perforated, are provided with cams I I, preferably so placed as to be vertically above the perforations when the clothes-board is in its horizontal, or substantially horizontal, position. These cams project horizontally from the parts h it. They have what may be termed a crescent shape, one side being concave and the other convex.

perforation, while the convex side is preferably bulged or elliptically convexed, so as to make the cam of sufficient eccentricity to do its work. These crescent-shaped cams lie within the slots g g of the movable inner jaws and operate against the edges of said slots.q

It will be noticed that the combination of tierod and cam forms the pivot or support on which each inner jaw is movably mounted.

Projecting horizontally from each of the inner jaws l is a pin Z. toward each other. A connecting-tube J receives at one end one of the pins Z and at the other end the othcrof said pins. (See Fig. 3.) This tube will be arranged in place at the same time when the other wringer elements are being assembled.

The operation of my presentinvention will be obvious from the foregoing description of the construction. The shelf or table G is adapted to be grasped and swung upward toward the upper roller, (see dotted lines in Fig. 2,) and also to be reversely moved into a horizontal position, or an approximately horizontal position, as seen in Fig. 1. Upon lifting this clothes-board the inner jaws will readily open or recede from the fixed jaws,

The concave side is coincidentwith the periphery of the adjacent These pins project so as to release the machine from a tub. By depressing the board the crescent-shaped cams are caused to act on the right-angled portions of the movable jaws, and as the tierod forms an unyielding pivot for the said board, this movement of the cams will exert a lifting force upon the tail ends of the jaws, which, together with the meeting of the rollers, will press the jaws toward the tub, thus gripping all the jaws tightly upon the tub, and simultaneously with this movement the lower rollers will be pressed upward against the other roller, for obviously when the movement of the jaw is obstructed by the tub, against which it comes in contact, the continued lifting pressure of the cams will force the lower roller upward, said roller being journaled in these movable jaws, and hence it is understood that when the clothes-board is depressed this one movement thereof presses the rollers tightly together, and also grips or clamps the machine.

The contour, design, outline, and attachments of the jaws, levers, and other parts may be varied considerably without departing from my invention, and I therefore reserve the liberty to reconstruct and modify the mechanical elements of the invention without departing from the spirit of the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a clothes-wringer, the combination of stationary outer jaws, squeeze-rollers, a suitably-supported clothes-board having cams at each end, movable inner jaws held upon a suitable support and provided with journalbearings and slotted extensions, within which slotted extensions the cams operate.

2. In a clothes-wringer, the combination of stationary outer jaws, upper and lower squeeze-rollers, a cam-provided clothes-board, movable inner jaws provided with journalbearings and slotted extensions, and a tie device supporting the clothes-board and having its opposite ends held by the outer castings.

3. The combination of the end castings having stationary jaws, the upper roller carried thereby, the inner movable jaws having slotted right-angled arms and horizontal journal-boxes, the lower roller having its journals in the said jaw-boxes, the clothesboard with its casting having enlarged ends perforated and provided with crescent-shaped cams, and the tie-rod running through said perforations and the slotted jaw-arms and held by the end castings, substantially as and forthe purpose specified.

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