signor to Lovell Manufacturing Company, Erie, Pa., a corporation of Pennsylvania Application March 10,

7 Claims.

Clothes wringers are commonly provided with what is known as a drip board. This drip board deflects the water as it is expelled from the clothes and deflects it so as to carry it on to a water board. In order that the water may be deflected in either direction, the drip board is usually pivotally mounted. Usually these reversible drip boards have been made with a plane flat base and different methods of assembling, or suporting the drip board have been provided. The present invention is designed to improve the drip board both as to function and as to cheapness of manufacture. Features and details of the invention will appear from the specification and 1 claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows;

Fig. 1 shows a front elevation of a wringer,

20' partly in section.

Fig. 2 an enlarged sectional view on the line 22 in Fig. 1.

Fig. 3 a section on the line 33 in Fig. 2.

The wringer frame, as shown, is made of pressed metal having a base 1, stiles 2, and top bar 3. It is provided with rolls 4, 4 operating in the usual manner. A water board 5 is provided with up-turned side flanges 6 and a seating portion 7 at the center. The seating portion is provided with a slot 8, preferably of key-hole shape adapted to register with a similar shaped slot 9 in the base. The water board is secured in place on the base by a bolt 10, the head of the bolt being passed through the larger part of the slot and brought into the smaller part for assembly.

An opening 11 is formed at the centers of the flanges 6. This opening is preferably struck up forming a lip 12 around the opening so as to form 1 a bearing surface. The drip board 13 has a base portion 14 and end flanges 15. Trunnions 16 are struck up and formed at the center of the flanges 15. The metal is given a cylindrical shape so as to fit the bearing opening 11 in the end flanges. In assembling the drip board the end flanges are sprung apart sufficiently to receive the trunnions 16.

It will be noted that the base portion 14 is formed with upwardly inclined sides, that is to say, the portion at one side is inclined to the portion at the opposite side, giving to the structure as a whole a somewhat trough shape. This has two very important advantages, first it stiffens the drip board and consequently makes it possible to form it of much lighter metal than 1931, Serial No. 521,433

where a straight plate is used, and, it increases the inclination of the up-turned portion of the drip board so that as the water reaches it, it is more definitely deflected back toward the tub than with the less inclination of the flat drip board. It is practical, therefore, to bring the edge of the drip board slightly closer to the center without danger of spillage over the edge. This permits of rolling the edge of the drip board, as at 1'7. This assists in stiffening the board and presenting a smoother surface as to any clothes that may reach it. Preferably the water board has shoulders 5a which the turned edges 17 overlap at the lower edge of the drip board. Thus a more effective screen against the outflow of water is accomplished.

The drip board is provided with a downwardly extending projection 18 at its center which engages an ordinary spring 19 secured to the water board. The effect of the spring is to yieldingly hold the drip board in adjustment when swung to either position. Here again the inclination of the sides of the bottom portion to each other and consequent stiffening of the metal makes the placing of the spring at the center more practical in that the stiffness of the drip board readily sustains the tension of the spring.

A shoulder 5a is provided in the drip board and the rolled edge 17 extends downwardly below this shoulder, thus more definitely preventing the passage of water from one side to the other of the wringer.

What I claim as new is:-

1. In a wringer, the combination of a frame; rolls mounted in the frame; and a pivotally mounted drip board under the rolls, the base po tion of the board having upwardly inclined sides with downwardly turned edges, said board having upwardly turned end flanges and pivotal mountings for the board on the end flanges.

2. In a wringer, the combination of a frame; rolls mounted in the frame; a pivotally mounted drip board under the rolls, the base portion of the board having end flanges with trunnions extending integrally in continuation of the walls of the flanges and forming pivotal supports for the board; and a spring yieldingly holding the board in adjustment, said spring exerting pressure on the trunnions.

3. In a wringer, the combination of a frame; rolls mounted in the frame; a water board mounted in the frame, said water board having flexible end flanges with bearing perforations therein; and a drip board having end flanges with trun- I nions extending integrally in continuation of the walls of the flanges, said trunnions extending into the bearing perforations.

4. In a wringer, the combination of a frame; rolls mounted in the frame; a Water board mounted in the frame, said water board having flexible end flanges with bearing perforations therein; a drip board having end flanges with trunnions extending integrally in continuation of the walls of the flanges, said trunnions extending into the bearing perforations; a downward projection at the center of the drip board; and a spring mounted on the water board operating against said projection yieldingly holding the drip board in adjustment.

5. In a wringer, the combination of a frame; rolls mounted in the frame; and a pivotally mounted drip board under the rolls, said drip board having end flanges with trunnions extending integrally in continuation of the walls of the flanges and forming pivotal supports for the board.

6. In a wringer, the combination of a frame; rolls mounted in the frame; a water board mounted in the frame, said water board having end flanges; a drip board having end flanges adjacent to the end flanges of the water board; and pivotal connections supporting the drip board, said pivotal connections being arranged between the flanges on the drip board and the flanges on the water board, said pivotal connections comprising pivotal members telescopically arranged one within the other, one of the flanges being resilient and permitting the separation of the flanges for assembling the pivotal members.

7. In a wringer the combination of a frame; rolls mounted in the frame; a water board mounted in the frame; a drip board pivotally mounted on the water board, said boards having end flanges, and one pair of flanges being provided with integrally formed trunnions on the flanges and the other pair of flanges having integral bearing surfaces receiving the trunnions.
