UNITED STATES PATENT OFFICE,

JAMES N, PEASE, OF PANAMA, N. Y., ASSIGNOB T() THE METROPOLITAN VASHING MACHINE COMPANY, OF MIDDLEFIELD, CONNECTICUT.

wRlNclNe-MACHINE.

Specification forming part of Letters Patent No. 19,0413, dated July 25, 1865.

To all lwhom it may concern Be it known that I, JAMES N. PEAsE, of Panama, in the county of Chautauqua, in the State of NewYork, have invented certain new and useful Improvements in ClothesY\/'1-iiig ers; and the following is a full description thereof, and the accompanying drawings, forming part of this specitication, represent one of the best forms of my machine.

Figure l is an end view. Fig. 2 is a section on the line S S in Fig. 3, and Fig. 3 is a front view.

Similar letters of reference indicate like parts in all the igures.

A is a rigid frame-work forked at the bottom to allow it to be placed upon a tub in the obvious manner.

B is the lower roller, and C the upper roller. These are made of rubber, secured upon shafts ot'iron,` and the shaft of each is formed with a crank at each end, the crank at one end standing at right angles to the crank at the other end.

The crank B carries a connecting-rod, D', which is adapted to fit over and slide on the fixed rod A at the other end. The crank C carries a connecting-rod, E', which is attached to the rod or connection D bythe pivot c.

The lower roll, B, is turned by the large addil tional crank M in the ordinary manner, and at each revolution the connectionsDand Eslide outward and return on the rod A in the man.

ner which will be obvious.

The crank B2 on the end of the roll B opposite to B carries a connection, D2, which at its other end slides on the fixed rod A2. The crank C2 carries the connection E2, which is hinged to the rod D2 by the pivot or rivet e2.

The upper roll, C, is adapted to rise and sink either in a direction strictly vertical or more or less inclined or curved. It is preferable to means be introduced to compel it toy turn at the same rate as its mate. Ordinary gearing does not well allow ot' the vertical motion of the roll C, because the gearing becomes disconnected; but my device compels both ,rolls to turn together and allows them to diverge and again approach freely. The connections D' and D2, being moved outward and inward on their respective slides A and A2, compel a corresponding movement of the connections E and E2, aud consequently compel the revolution of the upper roll, C, at a proper rate, whether it bears directly upon B or is con,- siderably elevated by treating a thick mass of clothing. The cranks B and B2, being set quartering or in planes at right angles to each other, or thereabout, as practiced withl locomotives andthe like, allow one to be effective while the other is on the deadpoint; so the rolls are always certainly and powerfully connected.

G is a stoutlever hinged at g. G2 is acorresponding lever hinged at g2 to the framing A. The shaft of the Lipper roll, C, is carried in holes in these levers, as indicated.

H is a narrow bearing-piece.

l is a lever which stands above G', and which is adapted to press on the piece H, so as to produce a sufficient pressure on the clothes passing through the rolls B C, there being corresponding levers and connections on each side ot' the machine to press down both ends ofthe roll C.

The bolts J, lxed on the frame-work A, serve both as guides for the levers Gr and G2 and as tulcrums for thelevers I. The nutsj, fitted to be adjusted on the bolts J, press on the upper faces of the levers I, either directly or through suitable washers or bearing-pieces, and by being set atvarious heights by the obvious process of turningthem correspondingly affect the position of the fnlcrums ot the levers. Screwing down on the nutsjinduces a greaterpressure on the goods being wrung, other thi-ugs being equal. v

K K are gear-Wheels mounted to mesh with the racks L L on the framing. The wheels K are lixed on the shaft 7c, which is carried in holes or bearings in the levers l, and may be partially turned by the hand-lever Mi. ln operating my machine it is common to take hold the crank M with the right and the lever M* i rolls, it being obviously proper to let the roll O rise when a thick article is being wrung and sink again with force when it has passed and a thinner mass is being treated.

The operation ot' my gearing K and rocks L differs from cams which have been before used to contine the rolls of wringers, because cams are subject to greater friction.' My levers I might, it' preferred, be connected to the framing at L by a iexible strap of rubber belting or other suitable material adapted to roll around smooth wheels at K, instead ot' the gearing and racks, and l consider such an equivalent for my gearing and racks. Such devices, which are nearly i'rictionless, possess the quality ot' self-adj ustment when the weight of the levers I is alone availed of to depress the upper roll, and in this respect are superior to cams, and they allow the hand ot' the operator to be applied so soon as free from the duty ot' introducing a garment and to aid by its weight or by its positive action upward or downward in inducing the right action oi' the apparatus on the fabric or clothes being squeezed. When the machine is to receive a verythin setof articles-as ladies7 collars-the screw-nuts j aie set down by the hand or by a suitable tool, and when to receive a thick lotas bed-blankets-these screwnuts should be turned in the opposite direction. In other Words, my levers l are hand-levers so arranged and combined that they may vbe also adjusted by the nuts j, and that they are or tend to be self-acting, so as to press by their own weight and the weightot' the hand upon the clothes, and to rise automatically without care or i'orethought by the operator so soon as a thick portion ot' the goods comes into the rolls.

This portion of the invention may obviously be worked without the adjustment provided by the nuts j, or with far less scope for such adjustment than is here provided. The movement of handlever Mis alone by the will of the operator, in anticipation ot' a thick mass, or automatically with the mobile weight of the hand when the mass is actually compressed, or partly by each, as by an active movement of the hand after the mass is struck, will provide for ordinary differences in thickness sufticiently; but it is for great variations in thickness very important to provide the nuts j or some equivalent means of adjusting at that point, in combination with the hand-lever ad justment, as described.

The screw N is for attaching the machine to atub and releasing at pleasure; but the turning of a screw against a tub is liable -to deface and abrade it. The shield P, turning or sliding on the pivot p, is adapted to receive the force of the screw N and transmit it without injury. The slot in the shield where it embraces p is sufficient to allow such a sliding motion as compensa-tes for the usual difference in the size ot' tubs, while the shield is free to move to a much greater extent by swinging, so as to very readily slide down upon the tub to its place and then be very effectually tightened.

It is not absolutely necessary that the reciprocating ends of the connecting-rods B', 8vo., shall slide on a rod so as to move in precisely right line. A sufticient approximation thereto may be obtained by providing a long link eX- tending either downward or-upward from the points ot'juncture e or c2, and pivoted to a fixed portion ot' the framing A. ln such case the reciprocating motion will be curvilinear, but it may be performed with less 'riction than on a slide, and it may be made to operate successfully.

I believe my mode of communicating motion from one roll to the other to be absolutely new in the arts in all the various applications where rolls or equivalent wheels, 85e., whether hard or soft, smooth or toothed, are required to be turned toward each other. I propose to employ my invention as above described for the feedmotion rolls of planing-machines, stavedressing machines, and other lumber and metal working devices also in calendering, printing, drawing, and pressing for any and all purposes whatsoever where this motioni. e. rotation in opposite directionsis required.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

l. The cranks B C and B2 C2 and rods D E and D2 E2, with suitable guides for the reciprocating ends of the connections, all arranged for joint operation, so as to transmit the motion ot' one roll to the other, substantially as and for the purposes herein specified.

2. The gear K and rac/k L, or their equivalents, in combination with the hand-lever M* and with the movable roll C, adapted to be operate-d by the weightofitselt and ofthe hand, substantially as herein specified.

3. The hand-lever Mtl, operating to depress one end of the lever I, in combination with the adjustingscrew-nutj orits equivalent, adapted to press upon and torm a movable fulcrum at the opposite end, substantially as herein specied.

et. The sliding and swinging shield-piece P, mounted and arranged substantially as and for the purpose herein set forth.

JAMES N. PEASE.
