DEVICE FOR WBINGERS.

Application. filed October 10, 1927. SeriaTNc. 225,294.

This invention relates to feed devices for use in feeding clothes or other goods to wring-ere.

The objects of this invention are to provide a feed device of this kind which is ethcient and reliable in operation and easy to operate and which includes a swinging feed member which is constructed to feed goods to all parts of the wringer rolls; also to provide a feed device of this kindnwhich is flexibly mounted in the wringer frame to enable any portion of the feed device to move into rorrect feeding relation to any portion of the wringer rolls; alsoto provide a feed device of this kind with means of iniproved construction for preventing the rolls from gripping or binding on the feed device; also to improve the construction of feed devlces this kind in other respects hereinafter speci- In the accompanying drawings- Fig. 1 is a perspective view of a portion of a wringer showing my device applied thereto.

Fig. 2 is a fragmentary detail of a portion of a wringer and-my clothes inserting device.

In the drawing like characters of reference indicate corresponding parts in each figure.

1 indicates the frame of a wringer of any suitable construction provided with the usual upper and lower rollers 2 and 3. t is a hearing bracket secured to one of the vertical members of the frame and so formed as to utilize the usual securing bolts a and. 6 of .35 the frame for securing the bracket thereto.

The bracket 4: is provided with lugs 7 between which a curved link member 8 is pivotally secured at one end by a vertical bolt 9. The link 8 is substantially arc-shaped in form and provided intermediately of its length on its inner or concaved face with a bearing lug 10 and a teat 11.

12 is an arm or bar member provided with lugs 13 and 14lextending above and below the to lug 10 of the link 8 and pivotally secured thereto by means of a vertical belt or screw 18.

It will be noticed particularly on referring to Figure 2 that the link is so formed :0 that the outer end thereof extending beyond the lug 10 forms a stop finger 8 against which the outer face of the arm 12 may have hearing engagement.

The arm 12 in cross section may be appronimately inthe form of a right angular triangle, the base of which extends horizontally substantially on a line with the point of contact between the upper and lower rollers 2 and 3 of the wringer and thereby forming a triangular rib the apex 12 of which engages the wet clothes applied to the face of the wringer rollers so as to force the clothes therebetween as hereinafter more particu larly explained.

The arm 12 is recessed longitudinally as indicated at 13, the base of the recess being provided with a longitudinal drain slot 14*.

. 15 is an anti-friction roller mounted. within the recess 13 between the ends 16 and 17 of the longitudinal recess 13, the ends of the roller being preferably recessed as indicated at 18 and a screw 19 screwed into the orifice 20 formed in each of the ends 16 and 17 so as to project inwardly therefrom into the recess 18 and thereby journal the roller 15 at its ends so as to freely revolve within the recess 18. Other means for journaling the rollers 15 011 the arm 12 may be provided if desired.

The outer end of the arm 12 is provided with a handle 12 by which the arm may be swung toward and from the wringcr rollers as desired.

In manipulating my device the clothes are picked up from the washing machine and the upper portion thrown over the arm 12 so as to extend from the inner side of the arm over the roller 15 and isheld at its end in this position with the one hand, while the operator grasps the handle 12 and swings the arm inward towards the wringer rollers. The article is thereby forced by the blunt edge or apex 12 in between the rollers until it is gripped thereby.

In order that the arm 12 will assume a parallel position to the rollers 2 and 3 1 provide the inner end of the arm 12 with a lug 19 provided. with a teat 19 between which and the teat 11 hereinbefore described extends a compression spring 21. hen the arm is swung inward to engage the article as above described'the inner end of the arm as illustrated in Figure 2 first engages the article and swings on this point as a fulcrum cempressing the spring 21 permitting the arm to swing inward at its outer end to a parallel positionwith the rollers 2 and 8 so that the article of clothing is forced evenly between the rollers from one end thereof to the other. By mounting the arm 12 on two pivots 9 and 13* and the link 8, this arm can assume different positions relatively to the rolls of the wringer so that by pressing on the handle portion 12? articles may be pressed into engagement with the wringer rolls at any portion of the length thereof and because a of the action of the spring 19 and the pressure exerted by the operator on the handle 12 the feeding arm will be pressed toward the wringer rolls at both ends thereof. Consequently if a comparatively thick article is placed [on the feeding arm near the pivot thereof and a comparatively thin article near the outer end of the feeding arm, the arm will upon pressure of the hand on the handle 12 assume a position in which both the thick andthe thin articles will be fed between the wringer rolls. The roller 15 is so positioned as to engage with at the upper wringer rolls 2 to prevent the edge portion 12 of the feeding arm from becoming jammed between the rolls.

If desired the arm 12 may be made in the form of an equal-lateral or isosceles triangle in cross section, or of other cross sectional shape, and a roller corresponding to the roller 15 provided above and below the arm.

Also the arm might be made independent .of the machine in the form of a bar and provided with a handle centrally of its length which is held by the operator so that the clothes supported upon the a m may be forced in between the rollers in the same manner as above described.

From this description it will be seen thatI have devised a very simple device which will readily allo w of the clothes being inserted between the rollers of a power driven wringer without any danger of the fingers of the operator being caught therebetween and injured.
