SAFETY DEVICE FOR GLOTHES-WRING ERS.

Application filed January 19, 1921.

To all whom it may concern:

Be it known that I, WILLIAM A. Sorrmm- LER, a citizen of the United States, and a resident of Glen Ridge, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Safety Devices for Clothes-Wringers, of which the following is a specification.

This invention relates to an improved safety device for clothes wringers, and is adapted toalso facilitate the feeding of wet clothes to the wringer, whereby not only is the safety of the operator insured, but the capacity of the wringer is increased, as clothes can be fed to it with but little interruption.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a side view of a wringer equip ed with 'my improved safety device, and ig. 2 is a detail section on line 2-2 in Fig. 1. Fig. 3 is a perspective view of the device detached from the wringer and showing a modified form of guard, and Fig. 4 is a reduced side view showing a modified form of securing means for the guard, whereby the guard is reversible.

The drawing shows only so much of an ordinary clothes wringer as to make the cooperation of the parts plain, the upright or side posts 10 of the wringer supporting the usual spring-pressed rolls 11. The device for insuring the safety of the operator and to facilitate and speed up the feeding of wet clothes, consists of a belt, the upper reach of which forms an apron for feeding clothes between the rolls of the wringer, since the upper reach passes between the rolls, and which is furthermore provided with a guard which, while it permits substantially flat articles to go through, and while it can be raised to permit an excess of material to go through, must be intentionally raised to permit the hands of the operator to get anywhere near the rolls of the wringer, and there is thus no possibility of having the fin are or hand caught between the rolls.

tructures for carrying out the inventionare illustrated in the drawing. The belt 12,

which is an endless belt and can be made of canvas or other similar tough fabric, is

mounted so that its upper reach passes be tween the rolls '11 and its lower reach passes underthe lower roll 11, and is supported at its ends by suitable rollers 13 which are mounted in bearings 14 which are arranged Specification of Letters Patent.

in the ends of the arms 15, which arms form parts of brackets which extend preferablyto both sides of the frame 10, so that when the wringer is reversed the functioning of the device is the same except in a reverse direction. The arms 15 are secured to back plates 16 which are secured to the posts 10, a pair of' these back plates being included in each bracket, and a bracket being fastened to each side of the posts 10 on each side of the wringer, and the arms 15 projecting therefrom in opposite directions, a substantial support for the rolls 13' and the belt 12 being provided.

The belt 12 is preferabl held under a tension, one form of doing t is being by means of springs 17 which abut against the bearings 14 onone end and on the other end against an adjustable fixture, in the form shown this comprising pins 18 in rear of each spring 17, which .pins can be fitted selectively in holes 19, so that if a spring weakens or a belt stretches slightly, the pins 18 can be moved toward the outer holes and the tension of the springs 17 thus increased.

In Fig. 2 ll illustrate, in section, one manner of making the side frames 15, which includes the tubular portion 20 to receive the springs 17 and also the pins 18.

The device can be further stiffened by suitable braces 21. It will thus be evident that when wet clothes are placed on the end of the upper reach of the belt 12 they are carried by the belt, which forms an apron, to the rolls 11, since the rolls 11, by their friction with the belt, drive the belt, and small articles, like handkerchiefs and towels and the like, can be fed rapidly on the belt and thus pass through between the rolls.

To guard against' thoughtless or accidental contact with the rolls, thus reventlng bodily injury, I provide a guar which in the form shown consists of arms or strips 22 pivoted at their top ends,'as at 23, to

ears 24 on the back plates 16 and which can swing freely upward, but which are limited bunched clothing or other materialpassing to the wringer will not cause a drag on the belt and the roller will permit the goods to pass on, but the guard will slightly raise, but still be in position to prevent accidental contact of the fingers of the hand with the rolls 11 and deter an operator from acting hastily to relieve any jamming of clothes between the rolls 11. When the accumulated or bunched material has passed the roller 28, the guard, by its own weight, will then descend to the position shown in full lines in Fig. 1, from its raised position which is shown in dotted outline in the same figure.

If desired, I may make a single guard to be used on alternate sides of the wringer, this construction being shown in Fig, 4:, in which a single pair of arms 22 is journaled, as at 29, at the top of the frame of the device and can be swung over to the other side of the frame, depending, of course, from which side clothes are being fed to the wringer.

This device can be made as a part of the wringer or it can be attached to a wringer now in use, the whole structure being light in weight so as not to add materially to the weight of the wringer itself.

I claim:

1. A safety device for clothes wringers comprising a pair of oppositely rojecting arms having bearings at their en s for supporting rollers in said bearings, a belt passing over the rollers and adapted to pass on its upper reach between the rolls of a wringer, and a guard hinged at its top end above the rolls and projecting at an angle downwardly and outwardly and having at its* lower end a transverse fender normally resting slightly above the upper reach of the belt, the guard being adapted to swing freely in an upward direction.

2- A safety device for clothes wringers comprising brackets having means for securing them to the supports of a wringer, each bracket including a projecting arm having a hearing at its end, rollers rotating in the bearings, a belt to pass over the rollers, a guard hinged at its top end to a pair of the brackets near the top thereof, the lower end of the guard resting on the arms near their outer ends, and a roller supported transversely near the bottom end of the guard and normally spaced slightly above the reach of the belt, the guard being adapted to swing freely in an upward direction.

3. A safety device comp-rising oppositely disposed brackets, each bracket including a pair of back plates with projecting arms, rollers mounted at the ends of the arms, a belt to pass over the rollers in each bracket, a guard including side strips hinged at their tops to the back plates and swinging freely thereon, the side strips being in line with the arms and adapted to rest thereon, and a roller secured on the side strips and disposed so as to be slightly above the belt when the strips rest on the arms.

In testimony that I claim the foregoing, I have hereto set my hand, this 18th day of January, 1921.
