CLOTHES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 287,782, dated October 30, 1883.

Application filed May 16,1883. (No model) I To all whom it may concern Be it known that 1, 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 Clothes-WVi-ingers; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

The object of this invention is .to produce a wringing or squeezing machine in which,

without the employment of adjusting-screws, the pressure can be put 'upon the rollers to force them together, and upon the tub to secure the machine in position for use, and also that both these pressures can be instantly and simultaneously relaxed when desired; To accomplish these objects,the machine itself, other than the clamping device, is made alever, and is turned or swung forward and back upon the pivots by which it issecured to its clamps. These movements so change the relation of the roller-bearings to each other and to the clamps as to give powerful pressures in the one position and wholly relax them in the other.

The peculiarities of the invention are indicated in the drawings, explained in the description, and specifically stated in the claims.

In the drawings, Figure 1 is a perspective View, showing one end of the machine in its working position with the rolls under press ure. Fig. 2 is anend elevation with the pressure relaxed, showing also an adjustable clamp such as I prefer to use for set-tub wringers. Fig. 3 is afront view, on a smaller scale, of the end of the machine. 7

The pressure-rollers A'B are mounted'in a frame composed, essentially, of two vertical end pieces, 0, and two curved springs, D,

O. 4 by a cross-bar, E. These seven parts are caused to move together as one on pivots H, which connect the end pieces, 0, to the tub clamps, and it is this movement forward and back which applies and relaxes the pressure in' the use of the machine.

Each of the end pieces, 0, has a flattened projection, O,to'which the lower end of the spring 1) is seen red by the bolt F, which also rigidly connected lengthwise of the machine'- 1 passes through the end of the cross-bar E, and

is held in place bya nut, G. The upper roller I has its bearings in concavities d,'formed for the purpose at the upper ends of the springs D. The upper part of each end-piece, O, is also concaved, as at c, to bear against the 5 projecting shaft or spindle of the upper roll, while the shafts of the lower roller pass through slots Sin the end pieces, and have their principal bearings upon one of the pivoted clampbars. l

The clamping device (connected to the machine, as above described, by pivots H) con sists, essentially, at each end of the machine, of two clamp-bars, J J and K, pivoted to each other at L. The bar J has a downwardly-proj ecting member, J, made either integral with it, as in Fig. 1, oradjustable on it, as in Fig. 2. The edge of the tub occupies the space between thelower portions of the two clampbars. This space may be varied in width, according to the thickness of the tubs, in machines having theclamp shown in Fig. 2, by adjusting the movable part J upon the part J, bringing the movable part against the exterior .of the tub, .where it is. held in place, when pressureis applied, by a cramping action, or v by a fine ratchet beneath the part J, which part may have a terminal projection to retain the movable part. The pivot L, by which the members of the clamp are united, passes through a slot, T, in the end piece, O,or may so pass to strengthenthe union of the frame and clamps. -Such slot is an are described from the pivot H. I I l r i The upper end of the clamp-bar K is curved to form a bearing, upon which the shaft of the lower roller will gradually enter when the' machine is tipped down from the position shown in Fig. I to the working, position of Fig. 2. From these figures it will beobvious 0 that such movement will lift the lower roll L into forcible contact with the upper one, and by crowding back the'upper endof the piv oted bar K will cause its lower end to press with much force against the edge of the tub, thus giving simultaneously the two pressures required. The sides of the slot S act also as lateralbearings for the lower shaft.

The clothes, entering the machine from the front,'are-kept from getting beyond the ends r00 of the rollers by clothes-guards N, formed inpressure and the tub-pressure are alternately tegral with the end pieces, 0, of the frame. applied and released by turning the roller- (See Fig. 3.) carrier frame upon said horizontal pivots,
