IMPROVEMENT IN WASHING AN-D WRINGING MACHINES COMBINED.

' Specication forming partof Letters Patent No. 122,441, dated January 2, 1872.

` improvements the following is a specification,

reference being had to the accompanying drawing, which is a perspective view of my machine.

The invention relates to that class of combined washin g and wringing machines in which three rollers are used, of which twothat is, the upper one and the lower one-are mounted in' movable bearings and are held in close contact with a third intermediate roller, whose bearings are not movable, and which is usually employed to drive the Vother two, its shaft being provided with a crank througlf which power may be applied. rhe invention consists in a novel combination and arrangement of three rollers and their actuating' springs, as

` will be fully explained.

. In the drawing myinachine is represented' as applied to a suitable tub, the side of which is broken away in order to more fully show the devices'. The frame consists of two end pieces, B, bottom girts B1, (one upon each side,) and top girt 13 2. E is the central rol1er,its shaft having a crank, E', upon one end, as shown. Its shaft is mounted in vertical slots I), and is therefore free to rise and fall within certain limits. lBy preference this roller is* made with a iiuted surface. A A are tongue-springs secured to the upper side of girt B2. rlheir free ends project beyond the fend pieces B and are connected with the shaft of roller D by means of rods a, the upper ends of said rods being threaded and provided with thumb-nuts C, whereby the tension of springs A may be increased and roller D pressed against roller E with any desired force. Dl is the wringing-roller. slots or in movable be'arin gs, and is held again st roller E by a bar-spring, D2, the pressurebein g regulated by a set-screw, d, working in a thread in. girt B2.

Although springs A A are practically two independent springs, yet for convenience Iusually make them in one piece, as shown.

In practice I usually employ a supplemental roller, F, over .which the articles pass as they go through between the wringing-roller D1 and roller E, this arrangement servingto keep said articles from contact with roller D, which is apt to be wet.

, I prefer to make roller E of rubber, as I nd that the clothesA are more readily freed from dirt by the action of the iiuted roller D against an elastic one than against an unyieldin g one.

It will, of course, be understood that the springs AA and D2 enable rollers D and D1 to yield so as to allow any desired thicknessof goods to be passed through by the action of rolle-r E operated by the crank.

I do not claim, broadly, tire combination of the three rollers D D1 and E; nor do I claim, broadly, applying the pressure to the lower roller by means of the side rods a; but

The herein-described combined washin g and wringing machine, consisting of the rollers D D1 E, springs A A D2, rods ai, adjusting-screws C d, and crank E1, these parts being combined and arranged for joint operation substantially as set forth. SOLON GONKLIN.
