Application filed September 12, 1923. Serial No. 662,285

To all whom it may concern:

Be it known that I, HERBERT E. WILLIAM- T son, a citizen of the United States, residing The principal object of this invention-is to provide simple means whereby when an article of clothing becomes caught in the wringer, as often happens, the same may be quickly released without the danger of the fabric being torn.

A still further object is to provide a quick release which may be operated with one hand, so that should the fingers of the operator become engaged in the rollers, the

other hand may be employed to effect the release.

A still further object is to produce a device of this character which is simple in construction, cheap to manufacture and one which will not interfere with the usual action of the wringer. j

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, I Figure 1 is a side elevation of my invention as applied to a wringer.

Figure 2 is a cross section of Figure 1,

Figure 3 is a cross section taken on the line 3-3 ofFigure 2, looking in the direction of the arrow.

Figure 4 is a cross section taken on the line 4-4 of Figure 2, looking in the direction of the arrow, and

Figure. 5 is an elevation taken on the line 5-5 of Figure 1 looking'in the direction of the arrow. I have sought to provide a clamp which contacts the housing of the upper roller in such a way as to move that roller into intimate contact with the lower roller and yet I permit the quick release of these rollers.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodimentof'my invention, the

numeral 5 designates the customary gearcasing of a power driven wringer having a casing 6 in the form of a casting secured thereto. This casting, together with the gear-casing 5, is adapted to rotate upon a shaft-tubing 7 within which the drive shaft 8 is positioned.

This drive shaft 8 has" a gear 9 mounted thereon, which gear meshes with a drive gear 11 secured to the shaft upon which the roller 12 is mounted.

The gear 9 and the gear 11 may be disengaged from each other by a hand lever 13. The customary bearings 14 and 16 are provided for this roller 12. Thus far the construction is that usually employed.

A cog wheel 17 is positioned adjacent one end of the roller 12 and is adapted to mesh with a'oog wheel 18 mounted upon a shaft 19 having a roller 21 thereon. The bearings for this roller are shown at 22 and 23 and are positioned in a housing 24. This housing is pivoted at 26 to a. U-shaped member 27, which extends downwardly and'beneath one end of a spring 28.

This spring passes beneath a cross-piece 29 of the casting 6, which cross-piece serves to maintain the spring under tension after adjustment has been made.

The opposite end of the sprin extends through the lower portion of a lin 31, ivoted as shown at 32 in a block 33. is block has a thumb-screw at extending therethrough, which thumbscrew is adapted to have its lower end 36 rest in a concave portion of a lug 37 formed integral with the housing 24.

By viewing Figures 1 and 2, it will be noted that through this arrangement the pivotal points of the link 31 are ofi-center with respect to the lower exeremity 36 of the screw 34.

By now adjusting the screw 34, the tension of the s ring28 will be caused to bear upon the U-s aped member 27 and upon the link 31. Thus tension will be transferred throughv the housing 24 to the rollers 21 and 12 It will thus be seen that when it is desired to release the upper roller from its contact with the lower roller iit is merely necesary to throw the screw 34: to the left in the drawings which results in the pivot 32 being thrown oil-center a sufficient amount to clear the lug 37 and consequently the link 31 will move to the dotted'lme position of Figure 2. This will allow the upper roller and its housing to be opened as shown, in dotted lines in Figure 1.

It is to be understood that the form of my invention, herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of" theinvention or the scope of the sub. joined claims.

Having thus described my invention, I claim 1. In a clothes wringer, a casting positioning one of the rollers of said wringer, a housing mounted above said casting, a spring positioned within said casting, a U- shaped member to which is pivotally secured said housing and which extends beneath one end of said spring, a link engaging the opposite end of" said spring and meansassociated with said link on the opposite end of said housing from said pivot for exerting a downward pressure on said housing.

2. In combination Withaolothes wringer a casting positioning one of the rollers of sa d wringer, a housing mounted above sa d casting, a spring positioned within said casting. a U-shaped member ;to which is pivotally securedsaid housing and which extends beneath one end of said spring, a link engaging the opposite end of said spring, means associated with said link and housing on the opposite end of said housing from said pivot for exertinga downward pressure on said housing, said means comprising a block pivoted to said link, a thumbscrew extending through said block. and :1 lug formed on said housing which said thumb-screw is adapted to abut.

In testimony whereof I afiix my signature.

HERBERT E. WILLIAMSON
