WILLIAM ROBERTSON, OF ERIE, PENNSYLVANIA, ASSIGNOR 'IO LOVELL MANUFAC- TUBING COMPANY, OF ERIE, PENNSYLVANIA, A CORPORATION OF PENNSYL- VA NIA.

Application filed May 31,

WVringers have been provided with rest plates which form a guide for entering the clothes between the rolls. These rest plates ordinarily extend from opposite the lower roll and are pivoted at some point above the lower roll so that the plates may be swung outwardly in case clothes wind on the lower roll. These plates are preferably formed of metal comparatively thin from top to bottom in order to give the rest plate a guiding surface of considerable dimension. There the clothes roll on the roll, thus forcing this rest plate outwardly from the roll, the edge of the rest plate is swung up by the engagement of the clothes on the roll so as to bring the strain incident to the clothes caught on the rest plate in a direction across-the edge of the plate and in line with its smaller dimensions, thus bending the plate and ruining the structure. The present invention is designed to correct this difficulty and consists in providing a stop for the rest plate which will permit the rest plate to swing to give a space for the clothes rolled on the roll approximately equal to that between the lower roll and the drip board and yet will maintain the rest plat-e with a cross dimension in the direction leading to the rolls sufficient to sustain the strain exerted on the plate where buttons or other obstructions become caught or engaged by the rest plate. Other features of the invention will appear from the specification and claims.

The invention is illustrated in the accom panying drawings as follows Fig. 1 shows an elevation of the wringer.

Fig. 2 a section on the line 2-2 in Fig. 1.

1 marks the wringer frame, 2 the lower roll, and 3 the upper roll. These are mounted in the frame in the usual manner and subjected to the tension of a spring 4, the spring 4 being adjusted by a screw 5 as commonly.

A drip board 6 is slidably and tiltably mounted between the sides of the wringer frame. It rests on pins 8 extending inwardly from these sides, these pins engaging stops 7 and the tilting movement being limited by stops 9 on the wringer frame.

Rest plates 10 are arranged at each side WRINGER.

of the wringer. They are provided with the up-turned ears 11 which are pivoted on pins 12 extending into projections 13 on the wringer frame. The structure so far described is one commonly used and the rest plate as shown is formed of comparatively thin metal. I

I provide projections 14 extending up-' wardly on the ears 11 above the pivots '12. Stop surfaces 15 engage the faces of the wringer frame thus limiting the upward movement of the rest plate as indicated in dash lines in Fig. 2. Clothes caught on the front edge of the rest plate in this position will exert strain on the rest plate nearly in line with the greater dimension of the rest plate so that the rest plate will not be injured by this strain. It will be noted also that the swinging movement of the rest plate is sufficient to give a space between the roll and the rest plate approximately equal to the space between the roll and the drip board so that the space for clothes rolled on the roll is not diminished.

What I claim as new is 1. In a wringer the combination of a frame; top and bottom rolls mounted in the frame; a clothes rest formed with a thin rest plate of greater cross dimension in a direction toward and from the rolls and up-turned ears at the ends of the plate; a pivotal mounting for the ears on the wringer frame; and a stop limiting the upward swinging movement of the rest plate to maintain the direction of pull of the superposed clothes going'to the rolls approximately in line with the greater cross dimension of said rest plate.

2. In a wringer, the combination of a frame; top and bottom rolls mounted in the frame; a clothes rest formed with a rest plate and up-turned ears at the ends of the plate; a pivotal mounting for the ears on the wringer frame; and a stop formed by projecting the ears above the pivot, said projections engaging the front face of the wringer frame and limiting the upward swinging of the rest plate.

3. In a wringer, the combination of a frame; top and bottom rolls mounted in the frame; a clothes rest formed With a rest plate and tip-turned ears at the ends of the plate; a pivotal mounting for the ears on the Wringer frame; a stop limiting the up- Ward swinging movement of the rest plate; and a drip board below the lower roll, the length of the ears and position of the stop permitting movement of the rest plate atfording a space between the roll and rest plate approximately equal to the space be- 10 tween the roll and drip board.

In testimony whereof I have hereunto set my hand.

WILLIAM ROBERTSON.
