Application tiled February 24, 1912. Serial N o. 679,707.

To all whom t may concern Be it known that I, SIMEON C. LAwLoR, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lmprovements in Mop-Wringers; 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 improvements in wringers, and particularly to such as are adapted for use in cooperative relation to a receptacle adapted to receive the exuded fluid, the invention being designed more particularly for the wringing of mops.

To this end, an ob] ect in view is the provision of means causing the parts of the wringer to assume a position when not in use adapted to facilitate the introduction ofa mop. l

With this and further objects in view, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter described and claimed.

In the accompanying drawing,-Figure 1 is a view in side elevation of a wringer einbodying the features of the present invention. Fig. 2 is a top plan view thereof.

Referring to the drawing by numerals., '1 indicates a pail or receptacle supporting base which is formed of a strap 1a set on edge, preferably of metal, and cross straps 1b, 1", connecting opposite points of strap 1a and forming the bottom or supporting portion of the base upon which the pail or other receptacle 2 is designed to'be sustained. The base 1 is carried `preferably on casters 3, 3, whose stems are journaled in supporting brackets 4, 4, each consisting preferably of a metallic strap formed witha loop or bend at its upper end inclosing the strap 1a and extending downwardly and being formed into a loop presenting two spaced horizontal portions which are perforated for the reception of the stem of the respective vcaster 3. vrlhe upper loop of bracket l is preferably riveted to the strapla, and the brackets are spaced about the base 1 suitably for supporting the same.

Upstanding from each side of the base 1 is a side frame, which, for facility of manufacture, may consist of a standard 5, and a standard 6, which areinerely continuations ofthe straps 1b, 1", the said straps being riveted to the strap 1a at the lower end portions of the standards. For facilitating disposition of the operating parts at the upper end of the side frames, each standard 5 is preferably perfectly upright, that is rises vertically from the base, while each standard 6 is formed laterally arcuate or curved to cause its upper end to approach the upper end of the respective standard 5, and the two standards are connected by a plate 7 which is riveted to both standards. A cross bar or rod 8 connects the two plates 7 having its ends fixed to the respective plates as by a shoulder at one side of the plate, and a swaged head at the other, not herein illustrated. Each plate 7 extends vertically above the respective standards 5 and 6, and is bent to a horizontal position across the upper ends thereof, and then again bent to an upstanding position, the last named part of the respective plate 7 being slotted, as at 9, forming guiding cani plates 10 and 11. The horizontal portion of each plate 7 is slotted, as at 12, for receiving and guiding an actuating arm hereinafter mentioned.

A bail-like lever 13 has its ends pivoted, as at 14, to the standards 6, and its intermediate portion outstanding above the base 1, and provided with a suit-ably attached tread plate 15. Pivoted to the respective sides of the bail 13, intermediate the pivot point and the tread plate, are the respective upstanding arms 16, 16,y which extend through and are guided by the respective slots 12, the slots being of a size loosely accommodating the arms, but of sufficiently snug fit to prevent any excessive lateral or edgewise play. Each arm 16 is bent edgewise substantially midway of its length, as at 17, for causing the upper end of each arm to travellaterally a greater distance than it would otherwise travel for the purposes hereinafter mentioned. It is to be noted also that the connection at the lower end of each arm 16 is spaced from the respective pivot 14 a distance suflicient for causing the lower end of each arm to always remain outside the vertical, transverse planes of the slots 12, so that each arm 16 extends on an incline longitudinally through the respective slot. A spring 18 is preferably arranged lat each side frame and has Lits upper end'c'onnected to the respective standard 6 adjacent plate 7,

A wringer roller 19 extends across from.

one side frame to the .other and is journaled in the plates 11 at one side of slots 9. A similar roller 2O is journaled in the upper ends of the arms 16, one of the journalsofV roller 2O extending Vbeyond the respective arm and being formed into an .operating crank 21. The journals of each roller 19, 20, preferably consist of a reduced shaft 22 fixed to and outstanding from a disk 23 which is in turn fixed to the respective roller, as by screws 24, 24. Each roller 19, 20, is thus suiiiciently short to lie between the Plates 11, 11, 10, 10, lwithout .end contact therewith, the reduced journals 22 engaging the respective plates. The upper edges of the plates 10 are rounded offto form cams or guiding plates, and in .operation are engaged by the respective journals 22 during reciprocal movement of the arms 16.

A rod 25 is-carried by each plate 7 and extends inwardly therefrom below the rollj ers 19, 20, and is bent bac-kwardly,that is in a direction toward and beneath roller 19 for serving as mop guides, the said rods extending over the edges of the pail 2, so as to insure disposition of the mop within the pail without necessitating grasping the mop j by the hand of the operator.

In operation, the parts being in the position seen in full lines in the drawing, the operator lifts the mop merely by the use of the handle or mop stick and lowers the mop clothY between the rollers 19, 20, down into the pail 2. After the mop has been introduced for its f-ull length, the operator places his foot on tread plate 15 and lowers the lever to the position indicated in dotted lines in Fig. 1, whereupon t-he parts assume the dotted line position as indicated in both figures. During this lowering movement of lever 13 the arms 16 have been drawn downwardly, being guided first by contact of the front edges of the arms with the front ends of the slots 12 until the journals 22 of roller 2O have come in contact with the upper edges of plates 10, whereupon the said plates serve as guides, so that the final relative position of the rollers, as indicated in dotted lines, is assured. Thus the downward pressure on the lever 13 tends to draw the roller 2O toward roller 17, and if an interposed mop prevents the full movement of roller 20, thel amount of pressure exerted by the foot on the lever 13 will govern the degree to which the mopmay be exhausted of its moisture by virtue of the capacity for varying degrees of pressurey on the mop. As soon as the mop has been iirmly clamped between the rollers, the operator rotates the rollers by actuation of crank 2l until the mop has been fed baclwarclly or upwardly .out of the rollers. Thereupon the operator removes his foot from tread plate 15, and the lever 13 is drawn by springs 1S back to its former position with the connected parts restored to the position indicatedin full lines.

ltis to be noted that the incline of the larms 16 causes the roller 20 to travel forthe other roller, each of said arms being bent intermediate its ends in a direction causing the roller engaging portion of the arms to be disposed awayfrom the fixedly supported roller, guides for the arms surrounding the same, and means for thrusting the arms longitudinally through the .ouides to an extent causing the bent portions to pass the guides, whereby the roller carried bv said arms is adapted to be moved laterally away from the other roller during the movement imparted by the longitudinal thrust of the arms.

2. In a wringer, the combination of spaced supports, a roller journaled therein, each support being formed with a guiding slot adjacent the roller and with a guiding cam surface leading to the slot, a pair of arms having their free ends movable past the slot, guiding means for the arms, a roller j'ourn'aledV in the free ends of said arms and having journals adapted to contact with and be guided by the cam surfaces into the slots, and means for reciprocating said arms longitudinally to carry the second-mentioned roller toward and away from the first-mentioned roller.

3. In a wringer, the combination with a base, of spaced side frames sustained thereby, each having a plate formed with an upstanding portion and an offset horizontal portion, the horizontal portion of each plate being formed with a longitudinal slot, a roller journaled in the upstanding portions of the plates, an arm movable longitudinally and substantially vertically through each slot, a roller journaled in the upper free ends of the arms, and a lever pivoted to the side frames and connected to said arms for actuating the same.

1. In a wringer, the combination of spaced side frames, each comprising spaced standards, and a connecting plate therefor, each iio iis

L neoted to Jche standards, and each connecting plate being formed With a longitudinal slot 1n its horizontal portion, a roller journaled in the upstanding portions of the l plates, an arm movable through each slot,

a roller journaled in the upper ends of the 10 arms, and means for moving said arms longitudinally through the slots.

In testimony whereof I aiiiX my signature in presence of tWo Witnesses.
