4 Claims.

This invention pertains to a clothes wringer employing a pair of rolls to extract water from material fed therebetween and is adapted for use on the ordinary power-driven domestic washing machine. o

The operator of a power-driven wringer is frequently injured by accidentally feeding herringers between the the pressure rolls and in high pressure rolls and seriously crushing any portion of the hand and arm passingtherethrough.

It is a principal object of this invention to provide a warning device adjacent the intake bite to prevent the operator from inadvertently feeding her fingers into the pressure roll bite.

More specific objects of the invention will become apparent from the specification and drawing and the novel features are summarized in the claims.

In said annexed drawing:

Fig. 1 is a side elevation wringer;

Fig. 2 is a transverse section of the same as indicated by the lines 2,-2 of Fig. 1; and

Fig. 3 is a detail showing the guard roll and stripper mounting.

Referring to Fig. 1, it will be seen that a substantially conventional two-mil wringer is attached to the conventional-washing machine post l through a reversible drive head I resting thereof improved on. The'head comprises a shaft carrying a pair of bevel gears adapted to engage'a third gear and drive the rolls in either directiomdependmg on which of the pairs of gears drivingly engages the third gear. A suitable shift handle It is provided to alternate the drive between respective bevel gears when rotation of the rolls is desired. All this is accomplished in a well-known manner and is not further explained.

Secured to the head 1 is a main frame It carrying a pair of wringing rolls, preferably mounted one above the other. The lower roll, designated at i2, is rotatably carried in the frame and driven from the head mechanism just described. The top roll 15 is not only rotatably carried, but is bodily shiftable vertically to accommodate articles at the bite between the two rolls. Suitable springs l8 hear at one end against-the roll it and at the other end against the top of the frame II to urge the two rolls together with resilient pressure in a well-known manner. Drain boards 20 are provided on each side of the roll ii to facilitate removal of water extracted'from the clothes andtoaidinfeedins.

My improved safety device comprises warning or guard rollers carried on an axis parallel with feed or drain boards gagement therewith, as shown in Fig. 2. I provide a plurality of deeply fluted rubber guard rollers 25 suitably journaled at the ends of the wringer. The guard rollers maintain suiiicient frictional contact with the adjacent wringer roll to be rotated by the former.

The rollers are each supported in slots "which are substantially concentric with the adjacent roll surface and are urged downwardly by springs '21 to normally lie in the position shown. The

rollers are journalled'in members 30 which are provided with lugs extending axially of the rolls 2t and thus prevent til radially about the to lie in respective slots shifting of the members guard rollers 25.

. To provide adequate safety to the operator the 20 are adapted to coact-witlfi; to define a limited space the adjacent rollers 25 be fed'to the roll bite. with this coactio under normal conditions, the operator will push clothes over the intake feed board into the roll bite. If. however. she allows her hands to approach too closely the pressure roll. bite, the top portions will be sharplystruck by the adjacent fluted roller 25 in the manner. above set out. To accomplish this, feed boards 20 are spaced as shown adiacent the top of the lower roll and in a position to closely approach the roll bite. In ordinary operation it is desirable to space the said feed boards from the adjacent roller 25 far enough to permit passage of clothes to the roller, but not far' enough to permit the operatorshand when in wringing position, passing between the feed board and roller without being struck by the latter.

The rollers 25 and feed or drain are duplicatedon each side of the wringer to frictional driving ento Fig. 2, that the a direction as to of material to the main pres- This reversely turning functions. First, it acts; as a warning to the operator and causes her. tot, jerk her hand away from the presthe rolls engage the, thereon provide positive resistance to the furtherpassage boards It roller. 'I'hese.strippers are on the out-feed side 4 of the wringer to strip clothes from the pressure rolls and prevent their passage between a rolland adjacent guard roller. The strippers are fixedly supported at their ends in bracket members II. This prevents shifting of the said strippers and at the same time maintains them in proper position with respect to the roll II as the members are guided up and down in the slots 2! during operation oi the device. It will be apparent that in a wringer employing the upper guard rollers there is very little, tendency for the clothes to, pass between the roll and rollers, since they normally fall downwardly over the outfeed drain board.

A stripper is associated with each guard roller 2! and is mounted to move with the roller when the same is bodily shiftedin slots 26. To this end, brackets ll support each stripper 28 at each end and likewise embrace each end of the adjacent roll 25 to provide for common movement of the guard roller and its associated stripper. When the guard roller 25 and adjacent stripper 28 are shiftably mounted in slot 26, as heretofore stated, the roller is urged upwardly against the spring 21 if an excess thickness of material does pass the roller and into the wringer. This movement may be utilized as explained in con-' nection with the guard ill in the patent to Charles w. Williams 'No. 2,299,777, issued October 27, 1942, to actuate suitable further safety mechanism to stop the wrinser action as there shown and described.

I desire to make clear that my improved guard roller safety device may be employed in other installations than the two-roll wringer shown and, further, that I do not limit myselr toguard rollers on both sides of the wringer. In cases where there is no roll reversing there need be no duplication of guard rollers.

It will be apparent from the foregoing d tion that I have provided a rolling device to prevent injury to an operator, which device also functions positively to provide resistance to any Other modes of, applying the principle ofmy invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

This application is a substitute for abandoned application Serial No. 173,859 filed Nov. Ill, 1937, entitled "Wrin'ger."

I therefore particularly point out and distinctly claim as my invention:

1. In a wringer, a frame, a pair of horizontally mounted rolls in said frame to, establish a clothes gripping bite therebetween, power means to drive said rolls, reverse mechanism to reverse the roll rotation, a guard roller adjacent the top roll and on each side of the bite, means to rotate said rollers in a direction opposite to the direction of rotation of the adjacent roll, feed boards-carried by said frame, one on each side of the lower roll and coacting with respective guard rollers to define a limited space on each side of the wringer through which material may be fed to said clothes gripping bite, and a stripper member interposed between each guard roller and its associated roll to prevent clothes from passing between the roller and roll.

; 2. In a wringer, a frame, a pair of rolls in said frame coacting to establish a clothes gripping bite therebetween, means to drive said rolls, aguard roller contacting a side of one roll, and a stripper completely interposed between each roller and pressure roll bite.

the associated roll, said roller being capable of resilient movement substantially tangent to said roll.

3. In a wringer, a frame, a pair of rolls in said frame coacting to establish a clothes gripping bite therebetween, a guard roller contacting one of said rolls and a substantially triangular stripper completely interposed between said one of said rolls and said roller, said stripper being in close contact with said one roll and with said roller for simultaneously stripping clothes. from said one roll and from said roller. 7

4. In a wringer, a frame, a pair of rolls in said frame coacting to establish a clothes gripping bite therebetween, a guard roller coacting one of said rolls and a substantially triangular strip per completely interposed between said one of said rolls and said roller, two of the sides of said stripper being concave, one of said sides being in close contact with said one roll and the other of said sides being in close contact with said roller one roll and from said roller.
