This invention appertains to clothes-wringers of the type generally vused in connection with domestic clothes Washing machines.

One of the primary objects of my invention is to provide means for feeding clothes through a Wringe, whereby accidents to the operator of the wringer are lessened, and whereby the work vcan be expeditiously and easily accomplished.

Another salient object of my invention is to provide a clothes-feeding attachment for wring' ers which can be quickly applied to or removed from a conventional wringer without any change to the wrlnger construction.

A further important object of my invention is to .provide a clothes-feeding attachment for wringers embodying an endless conveyor belt having one stretch thereof placed between the wringerv rollers and driven thereby, with idle rollers supporting the ends thereof, novel means being provided for detachably and adjustably securing the ends of the idle rollers to the wringer drain-board.

A still further object of my invention is to provide a novel guard for the hands of the operator disposed above the conveyor belt and arranged to partially house the upper wringer roller, the guard being movable withthe upper wringer roller. whereby said guard will automatically position itself in accordance with the thickness of the clothes being passed through the wringer.

With these and other objects in view, the invention vconsists in the novelconstruction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure l is a transverse sectional View through a clothes-wringer showing my novel device applied thereto, the section being taken substantially on the line I-I of Figure 2, looking in the direction of the arrows.

Figure 2 is a front elevational view of a wringer, showing my attachmentapplied thereto, parts of the view being shown broken away and in section.

spending parts throughout the several views, the

letter A .generally indicates my novel clothesfeeding attachment for a wringer W. The wringer W can be considered -as of the ordinary type now generally used on domestic clothes washing machines, and the same has been illustrated 8 merely to show the use of my invention.

As shown, the wringer W includes the usual

side frame plates

5 and 6 connected at their lower ends by a cross-bar l, and at their upper ends by the spring housing or head 8. A drain-board 9 is l0 secured to the upright

side frame members

5 and 6. vThe shafts for the upper and lower wringer. rollers I0 and II are mounted in bearing blocks I2, `and the upper bearing blocks arearranged for sliding movement, whereby the upper wringer l5 roller I0 can rise and fall according to the thickness of the clothes being passed through the wringer. These blocks, and, consequently,v the upper wringer roller, are normally held down by a leaf spring I3, the ends of which engage the 20 upper terminals of the bearing blocks for the upper Wrlnger roller. 'I'he tension of the leaf spring I3 can be adjusted by means of a hand screw I4 carried by the head or spring housing 8. 'I'he wringer rollers are power-driven, and the 25 means for driving the rollers forms no part of the present invention, and, hence, has not been illustrated.

My clothes-feeding attachment A comprises an endless conveyor belt I5, which can be formed 30 from any desired material, such as rubber, fabric, or the like. The upper run or stretch of the conveyor is passed between the wringer rollers I 0 and II, as can be clearly seen by referring to Figures 1 and 2 of the drawing. 'I'he belt can easily be 35 applied to the machine by merely removing the rollers and the head 8 from the wringer frame. 'Ihe terminals of the belt I5 travel over idle rollers I6 and I 1, which are supported on transversely extending rods I8. 'I'hese rods rest on 40 the upper edges of the side walls of the drainboard 9, and these side walls gradually incline downwardly toward the outer ends of the drainboard.

In order to hold the rods I8 in proper position, 45 the terminals thereof have connected therewith contractile coil springs I9, and these springs have their lower ends connected to the screws 20 of the adjustable clamps 2|. The clamps 2| are preferably of a U- or C-shape for straddling 50 the side wall of the drain-board 9, and by tightening the screws 20 the clamps can be quickly and easily applied to the drain-board.

Great stress is placed upon the use of the clamps 2 I, in that my attachment can be quickly liliV and easily applied to the wringer without marring the wringer in any way and without changing the construction or shape of the wringer. Further. each of the clamps is adjustable independently of the other, and thus the rollers i8 and I1 can be positioned on the drain-board to the best advantage.

Where the attachment is t0 be sold with the wringer, the manufacturer of the wringer can -place outwardly extending lugs or pins 22 on the drain-board for receiving the lower ends of the springs I9. If desired, a removable rod can be passed throughthe side walls of the drain-board for receiving the lower ends of the coil springs, and a rod can be usedinstead of theclamps or pins. In this instance, the desired adjustment of the rollers is obtained by using coil springs of the desired length and tension.

In connection with my clothes-feeding attachment, I utilize a novel guard G, as an extra protection to prevent the hands of the operator from being drawn into the wringer. This guard G includes an elongated body 25 of a substantially inverted U-shape in cross-section; and this guard straddles the upper wringer roller I0. The ends of the body 25 have formed thereon outwardly extending arms 28, which are placed between the upper bearing blocks I2 for the wringer roller I0 and the terminals of the leaf spring i3. By this construction and arrangement, the guard will rise and fall with'the upper wringer roller, and, thus, the position of the guard will accommodate itself according to the thickness of the clothes being passed through the wringer.

In lieu of using the guard G, I canemploy at guard plates 21, 'as shownin Figure 3 of the drawing. 'I'hese guard plates 21 extend in front of the upper wringer roller andare provided with slots 28 for receiving guide pins 29 carried by the wringer, so that the plates can rise and fall. If desired, the plates can be mounted for swinging movement instead of sliding movement.

Obviously, my clothes-feeding attachment will function irrespective of the direction in which the wringer rollers are being operated.

From the foregoing description it can be seen that I have provided a novel device for feeding clothes through a wringer which will expedite such work, and which will lessen the danger of accidents occurring to the operator of the wringer.

Changes in details may be made without de; parting from the spirit or the scope of my mvention, but what I claim as new is:

1. In a safety wringer, a wringer frame, upper and lower wringer rolls rotatably mounted in said frame, a drain-board disposed below the rolls having upturned lateral side walls inclining downwardly toward their outer ends, an endless clothes-feeding .belt positioned above the drainboard having its upper stretch arranged between the wringer rolls, idle rollers supporting the belt having trunnions restingupon the upper edges of the side walls of the drain-board, contractile coil springs connected with the trunnions of the idle rollers, and means connecting the springs to the drain-board for holding the idle rollers down and away from the wringer rolls.

2. In a safety wringer, a wringer frame, wringer rolls rotatably mounted in said frame, a drainboard disposed below the rolls having upturned lateral side walls, an endless conveyor belt disposed above the drain-board and. having its upper stretch disposed between the rolls, a pair of idler rollers for supporting the belt, supporting trunnions for said idler rollers disposed upon the upper edges of the side walls of the drain-board, clamps detachably secured 4to the drain-board and projecting laterally therefrom, and contractilecoil springs connecting the trunnions with the clamps for holding the idler rollers down and away from the wringer rolls.

3. In a safety'wringer, a frame, a pair of wringer rolls rotatably mounted in said frame, a

drain-board positioned below said rolls having upturned lateral side walls, an endless clothesconveying belt disposed above the drain-board and having its upper stretch arranged between the rolls, idler rollers supporting the belt, supporting trunnions for the rollers resting upon the upper edges of the side walls of the drain-board, outwardly extending pins on the drain-board,

- and contractile coil springs connecting the trunnions with the pins for holding the idler rollers down and away from the wringer rolls.
