Speccaton of Letters Patent.

Application filed .Tune 7,1906. Serial No. 320,616.

To (L7/Z when?, it may concern:

Be it known that I, HAROLD OoLBY, a citizen of the United States, residing at Spokane, in the county of Spokane, State of 1Washington, have invented certain new and useful improvements in Mop-lVringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the art of scrubbing, and consists more especially in an improved wringer for mops or clothes whose details of construction are set forth below, and which is illustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of this entire machine, ready for use as a mop wringer. Fig. 2 is a central vertical section showing the device in use and illustrating how a tub may rest upon the base. The second view illustrates how a spring or springs could be coiled on the rod which supports the bail, while the first view illustrates contractile springs as connecting the lower ends of the main levers.

Referring to the drawings, the numeral 1 designates a base, here shown as fiat so that a tub may rest thereon as seen in Fig. 2; and from the sides of this base rise two uprights 2, while to the rear extend two side supports 3 which are connected at their outer extremities by a transverse rod 4. Pivoted in the upper ends of the uprights are two pairs of main levers 5, each preferably bent at an obtuse angle near its upper end as at 6, and each preferably pivoted to the upright at a point 7 within this bend. The two levers of each pair occupy reverse positionsso that their short u per arms lie close together and nearly parallel when the long arms are forced apart as shown in Fig. 2.

Power is applied through a foot-lever 10 which preferably comprises the transverse member of a U-shaped bail 11 whose side arms extend from the foot-lever backward in parallelism over the base and are sufficiently spaced from each other to span a tub of ordinary size. At their rear ends they are pivoted as at 12 upon the rod 4, and if desired a s ring or springs 3() (see Fig. 2) may be coi ed on this rod and exert a tendency to normally raise the foot-lever.

13 designate two toggles one at each side of the machine, whose outer ends 14 are ,at their ends.

pivoted to the lower ends of the main levers 5, and whose inner ends are pivoted to each other and to the side arms of the bail as at 15. In Fig. 1 I have shown two contractile springs 31 connecting the points 14 and standing outside the mainlevers 5 and within the uprights. These springs may be used in stead of the single spring 30, and if they are employed their tendencyv is to draw the lower ends of the main levers together and raise the foot-lever as explained below.

20 designate two rollers which may be of rubber, wood, or other suitable material, and these are fast upon spindles 21 which are journaled in the upper ends of the main levers. The said rolls 2() are cylindrical rolls whose outer surfaces are concaved to the extent of one-sixteenth part of an inch,

thus making the diameter of said rolls in the center or at a point equi-distant from the ends one-eighth part of an inch less than Said concave surface makes an arc or chord of a circle extending from the ends of said rolls inward, and concaving toward the center of the rolls and thence out to the said ends. One of the spindles may be continued into a crank handle 22 if desired. 23 are gears which may also be mounted on these spindles if desired, and they are of such size and shape that they will intermesh When the faces of the rollers all but touch each other. The parts are of desired proportions and materials, and if pre'- ferred the springs may be entirely omitted.

When this device is in use as a mop wringer, the tub usually sits upon the base within the bail. As the operator lifts the mop-head out of the tub he raises it (still dripping) and lets it down between the rollers, and then by applying pressure to the footlever the toggles cause the main levers to swing and the rollers to be approximated so as to squeeze the mophead between them. If suflicient wringing is not accomplished by forcibly withdrawing the mop-head, the crank-handle may be used to supplement this operation. When this device is used as a wringer for clothes, the bale is depressed further than when used as a mop wringer, so that its foot-lever rests upon the floor or the base as seen in Fig. 2, and willretain this position where it will not interfere with the insertion or removal of the tub, above which latter the rollers stand and are operated in the usual way. If the spring 30 is employed, the removal of the foot allows the bail to rise TOO and the rollers to open at any time; if the springs 3l are employed, itis possible to depress the foot-lever until the toggles are straight or their central pivots have passed a straight line between their end pivots, when the springs 3l will hold the foot-lever depressed; and if no springs are employed, it will be necessary to lift the foot-lever before inserting the article to be wrung out.

Itis possible to use this device in the ordidary operation of washing clothes and the like. When so employed, the tub containing the wet pieces of wash is placed on the base, and said pieces are successively raised by hand or with the laundry stick and inserted between the rollers, the pressureis then applied by the foot-lever, and by turning the crank the clothes are wrung out and forced up where they can be passed on to the next operation-the water wrung out meanwhile running back into the tub.

What is claimed as new is:

The herein described wringer, the same comprising a base having spaced uprights, duplicate pairs of main levers of which each lever is bent at an obtuse angle and pivoted at its bend to one of said uprights, two rollers connecting the up er ends of the levers, gears on the ends o said rollers a crank handle on the shaft of one roller, toggle levers connecting the lower ends of the levers of each pair, contractile springs drawing said lower ends normally toward each other rigid supports projecting to the rear from sai uprights, a transverserod connecting the outer ends of said supports, and a U- shaped bail whose ends are pivoted on said rod, whose sides are pivoted to the central pivots of said toggles and whose transverse central piece forms a foot-lever, the position of said rod being such that when. said footlever is completely depressed the central pivots of the toggles are below a line through their end pivots, for the purpose set forth.

YIn testimony whereof I hereby affix my l signature in presence of two witn esses.

HAROLD COLBY. Vitnesses:
