JOHN S. LASH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED CLOTH ES-WRINGER.

Specification forming part of 'Letters Patent No. 59,041, dated October 23, 1866.

To all whom it may concern:

Beit known that I, JOHN S.Lnsr1, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and Improved Viringer; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawings, making a part of this specification, in whichd Figure 1 is a front view of the improved wringer. Fig. 2 is a cross-section through the supporting-plate of the driving-wheels, taken in the vertical plane indicated by red line 00 Fig. 3 is a longitudinal section, taken in a vertical plane through the center of the wrin ger. Fig. 4 is an inside view of the driving spurwheel of the upper roller and its link-connection with the crank-arm of said roller.

Similar letters of reference indicate corresponding parts in the several figures.

' both rollers of a wringer, one of the rollers Vbeing allowed to yield bodily, as above stated,

by means of two spur-wheels, which are both applied to stationary bearings so as to always remain in gear with each other, the upper spur-wheel being connected to a crank-arm on the shaft of the upper roller by means of a compensating link or pitman, as will be hereinafter described.

To enable others skilled in the art to understandmy invention, I will describe its construction and operation.

In the accompanying drawings, A A represent the two uprights which form the frame and supports for the wringingrollers and clamps. In front of these uprights is a crosspiece, A', which securely connects them together, and in rear of the uprights are clamping-pieces B, by means of which the machine is secured to a wash-tub or washing-machine.

C C' are rollers, which may be constructed of india-rubber applied to metal shafts D D', or which may be constructed in any other suit' able manner, and of any of the well-known materials of which wringing-rollers are made.

The ends of the shaft D of the lower roller pass through the uprights A A, and have their bearings therein; but the ends of the upper roller-shaft, D', have their bearings in vertically-slidin g blocks a a, (shown in Fig. 3,) which are guided in grooves formed in the uprights A A. The 'blocks a a allow the roller C' to rise and fall, restrained only by a spring, b, which is introduced between a cross-head, E, whose ends rest upon said blocks, and an eccentric or cam, c, and a cross-bar, F. eccentric or cam c is used for increasing or diminishing the pressure of the upper roller upon the lower one at pleasure, so as to adapt the rollers for wringing large and small articles.

The frame, the clamp for sccurin g the machine to a wash-tub, the device for regulating the pressure of the spring upon the upper roller and adjusting this roller to adapt the machine-for wringing very large or very small articles, and the rollers may all be constructed as I have above described, or in any wellknown manner.

One end of the shaft D ofthe lower roller, C, projects from the side of frame A, and has a hand-crank keyed on its extreme end. This projecting end of shaft D is supported in a bearing, G, which is rigidly secured to the upright A, and between this upright and the bearing G a pinion spur-wheel, J, is keyed upon the roller-shaft D. (Shown in Figs. l and 3.) This wheel J engages with the teeth of a corresponding spur-wheel, K, which has its bearing in the plate G, as shown in Fig. 3. It will be seen that thewheelK has au axis or stud projecting from its outer side only; the inner side, or that which is nearest the upright A,

is plain.

There is a space between the plain face of the wheel K and the upright A, to allow the end of the shaft D' of the upper roller, O', to project a short dist-ance through a vert-ical obA long slot, e, which is made through the said upright, and to receive upon it a short crankarm, g, by turning which the roller O' will be turned;

To a slight oiiset on the face of the wheel The. y

K, and at the required distance from the axis of this wheel, a link or pitman, h, is pivoted by a pin, i. (Shown in Fig. 4.) The opposite end of this pitman or link is pivoted to the outer end of the crank-arm g, so that when wheel K is rotated the link h carries with it the arm g, and thus rotates the wringingroller C". p

The object of' thus connecting the wheel K to a crank-arm, g, upon the shaft of the upper roller, C', is to cause said wheel to rotate this roller as it changes its position without disengaging the wheels or producing any binding or undue friction. The axes of the two driv in g-wheels J and K always remain at the same distance apart, and consequently they will run smoothly; but the aXis of the roller-shaft D is constantly changing its position with respect to the aXis of its driving-wheel K, and for this reason the compensating-link 71, is used, which will accommodate itselt` to the ecccntricity of the axis of shaft D with relation to the axis of the wheel K, as indicated in Fig. 4 by the aid of the red lines.

I am aware that it is not new to employ compensating devices for rotating the shafts ot two wringing-rollers7 and therefore I do not claim this broadly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of thejointed compensatin g-link h and arm g with the non-slidin g gears J K and the rollers C C', substantially in the manner and for the purpose described.
