CLAUDE B. DAVIS, OF RICHMOND, VIRGINIA, ASSIG-NOR OF ONE-HALF TO J. WALTER KEELING, 0F DANVILLE, VIRGINIA.

WRINGER ATTACHMENT FOR TUBS.

Application filed September 5, 1919.

following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.

This invention relates to clothes wringing attachments for wash tubs and it has for its object to provide an article about which may be passed the fabric to be wrung and which will hold securely to the usual sheet metal wash tub, against the strains that are incident to the wringing operation.

A further object of the invention is to provide a construction that will be extremely simple and correspondingly cheap of manufacture and which while holding tightly in use, may nevertheless be easily and quickly removed and as readily applied.

In the drawings:

Figure 1 is a perspective view showing the article in use upon a tub.

Fig. 2 is an enlarged perspective view of the attachment, a portion of a wall of a wash tub being shown in sectional perspective to illustrate the manner in which the peculiar U-shaped clamp serves not only to fasten the attachment to the tub wall, but also to prevent rocking of the attachment upon loosening of the clamping screw and other annoyances due to the violent wrenchings to which an attachment of this character is ordinarily subjected.

Fig. 3 is a transverse section on line 3-3 of Fig. 2. 7

Referring now to the drawings, the present attachment comprises a hook made of a rod or bar of metal that is bent to form the bill 5, the shank 7 and the connecting bend 6. The shank stands horizontal, and at its end it is herein shown as bent at right angles away from the bill but in the same plane with the remainder of the hook and it is flattened at its side remote from the bend of the hook to lie snugly against the inner arm 8 of a U-shaped clamp which includes also the outer arm 9 and the curved or bent intermediate stem 10, this flattened portion of the hook being shown at 11 and being secured to the inner arm of the clamp by rivet v12- Specification of Letters Patent.

Patented Jan.'6', 1920.

Serial No. 321,843.

The spacing of the arms of the clamp is slightly more than thethickness of the head 13 that is formed by bending outward over a wire the upper edge of the usual sheet metal wash tub 14. Through the outer arm 9 is formed a threaded perforation 15 with which is engaged a thumb screw 16, the head 17 of which is disposed outwardly. The inner end of the thumb screw 16 is reduced in diameter and swiveled as shown at 18 in a perforation formed centrally through a U-shaped plate or clamping jaw 20 which is disposed between the arms 8 and 9 the parallel outturned

end portions

21 and 22 snugly but slidably engaging the parallel side edges of the outer arm 9. The perforation is countersunken so that the extremity 19 of the thumb screw may be upset thereinto, thus to pivotally connect the thumb screw with the movable clampin jaw that cooperates with the inner arm 8 which forms the opposing jaw.

By reason of the

ends

21 and 22 lying snugly against the side edges of the arm 9, this jaw 20 is prevented from oscillating on the thumb screw. By reference to Fig. 2 of the drawings, it will be noted that the jaw 20 is so positioned with respect to the bend 10 of the clamp, that when the latter is engaged over the beaded upper edge of the wash tub and the thumb screw is operated to force the jaw 20 against the outer surface of the tub, said jaw will enter snugly beneath the bead 13 and thus will not only serve to prevent upward withdrawal of the attachment from the tub, but will prevent rocking of the clamp on the tub, with the same efiiciency as if a plurality of set screws were employed and thus will the hook be held in proper position at all times. Furthermore, with this construction an extended bearing surface is provided between the outer wall of the tub and the movable clamping plate, which latter may be initially bowed on a shorter radius than that of the tub, as indicated in dotted lines in Fig. 3, so that it will be flattened or spread to the curvature of the tub wall when the thumb screw is operated and thus will hold the thumb screw more securely from unscrewing. Finally, twisting of the attachment under the strain of wringing and its eventual dislodgment from the tub, as well as buckling of the wall thereof, are avoided by the construction described. The jaw closely underlies the bead and not only holds the clamp to the tub wall but holds it down upon the bead thereof, and the inner arm of the clamp is elongated so as to have ample bearing against the inner face of the tub wall from its bead for quite a distance downward. The depending right angular stem of the hook is riveted to this arm of the clamp, so that both are strengthened and the shank of the hook is rigidly sustained in horizontal position, projecting inward over the tub from a point about flush with the bend of the clamp.

What is claimed is:

A wringer attachment comprising a clamp including an inverted U-shaped body for engagement over the beaded upper edge of a wash tub, a U-shaped clamping jaw disposed between the arms of the body below its bend with its ends outturned and slidably embracing the side edges of the outer arm, means for adjusting the jaw toward and away from the inner arm, and a hook carried rigidly by such inner arm to receive an article to be wrung.

In testimony whereof I aflix my signa ture in the presence of two witnesses.
