CLOTH Es-WRINGER.

SPECIFICATION forming part of Letters Patent No. 377,545, dated February 7, 1888. v

Application filed June 23, 1856. Serial No. 206,013. (No model.) l

To all whom; it may concern.-

Be it known that I, WARREN M. YB RINKRR HOFF, a citizen of the United States, residing at Auburn, in the county of Cayuga and State or" New York, have invented certain new and useful Improvements in Clothes-Wringers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to ro which it appertains. to make and use the same. My invention is an improvement in stops for clothes-wringers, and the object of the same is to provide an efficient stop for the class of wringers provided with pressure-regulating devices.

In the drawings I have shown two forms in which I have contemplated applying my invention, and have fully disclosed such inven tion in the specification and claims.

In the drawings, Figure l is a longitudinal vertical section of a woodenframe wringer with one form of my stop attached thereto. Fig. 2 is an end elevation of such wringer. Fig. 3 is an end elevation showing a modified construction.

The frame A is of the ordinary or usual construction, and the rollers B B are mounted as usual, the lower roll in rigid and the upper in movable bearings. The springs CG are in this 3o case also of wood, with an auxiliary rubber.

sp ring,O', interposed between them. The end standards of the frame are provided with slots, within which are the movable bearingsfor the upper roll', and into which Vvthe ends of the 3,5 springs C C project. The springs 'are forced downward and the pressure applied to the "rolls and their bearings is increased and diminished by the setscrews D D, or in any other suitable manner. In order to provide a 4o stop which will arrest the pressure exerted at such point as to produce the result desired, I employ in this instance two rectangular frames, e, one of which is placed at each end of the wringer within the slot of the standard, and the ends of the lower spring are passed into such frames and rest upon the lower cross-bar of the same. A bolt, e', passes through the upper cross-bar of each frame and is provided with a nut at its lower4 end. This bolt may be reversed and the nut placed at the upper end 5o instead-ofthe lower, if desired.l The opening in the upper cross bar of the frameis large enough to permit said frame to move easily upon the bolt e.

The movable bearings of the upper roll being immediately beneath the frames e, such bear-l ings and the roll with them are forced down# ward as far asthe adjustment of the bolt e' will permit. This adjustment is such that the rolls are brought firmly in contact, but- Without any 6o injurious pressure uponeach other or upon their bearings. In this position the slightest upward movement ofthe movable bearings of the upper roll will cause them to .receive the arrested pressure, thereby insuring the full 6 5 measure of efficiency in the operation of the f machine. f

In Fig. 3, instead of employing the rectaugular frame, I construct the bolts c in such manner as toeft'ect the same results. The bolts 7o e' in this case are made longer and pass through the ends of both springs C C, the lower end of each bolt entering a nut, e-, beneath'the lower spring, said nuts formingstops in this instance; or the head'of the bolt may be placed beneath 75 the spring and have its nut at its upper end above the cross-bar of the wringerframe. I preferto, place such bolts inside the end stand ards of the wringer, as clearly shown indotted lines in Fig. l; but they may be placed inthe 8o same position as' in the other construction by making theml capable of a vertical movement through the upper spring and cross-bar.v In some cases the frame e and the movable bearings are made integral or in one piece. If

.made separate, they may, if desired, be connected together. In practice it is designed that the stopshall be adjusted by the maker and the article sold and used as it leaves the manufactory until 9o t* the wear of the rolls or other parts shall require a new adjustment.

My improved stop is effective in protecting y the rolls and their bearings from undue wear andthe frame from much injurious strain, is durable, and by its means great nicety ofadjustment is secured.

I do not confine myself tothe exact construetions herein shown and described, as great variations may be made in the same without departing from the spirit of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. The combination, with a wringer-frame, of rolls mounted therein, pressure-regulating devices for said rolls, a stop interposed between said pressure-regulatin g devices and said rolls or their journals, and a bolt extending from and connecting the said stop with a stationary part of the wringer, substantially as described.

2. The combination, with a wringer-frame, of the rolls therein, a movable bearing for one of said rolls, a stop having a part engaging
