MOP-WRINGER.

SPECIFICATION forming part of Letters Patent No. 415,195, dated November 19, 1889.

Application filed July 9, 1889. Serial No. 316,903- (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES GILLMANN, a citizen of the United States, residing at East Park, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Mop-\Vringers; 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.

My invention relates to improvements in mop-wringers in which the wringing-rollers are adjusted to work in stationary guides at the top of a portable standard, as hereinafter explained, this standard being so arranged as to receive a pail beneath the rollers; and the objects of my improvement are, first, to provide a mop-wringer which is at once portable, worked by foot-power, and yet disconnected with the pail, so that the latter may be more convenient for emptying and refilling; second, to furnish a more elfectivc pressure for bringing the wringingrollers together by means of the curved guides in which the roller-bars work. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure] is a side elevation of the entire wringer, showing the pail in position in the standard and the treadle depressed to bring the rollers together. Fig. 2 is a similar View showing the pail partly within the standard and the treadle raised by the springs to the position which separates the wringing-rolls widely apart. Fig. 3 is a perspective view of a device, showing the pail in position, the treadle depressed, and the rollers wringing the water from the mop as it is pulled from the pail between the rollers; and Fig 4 is an enlarged view of the upper part of the frame of the standard, showing the rollers in their depressed or adjacent position, the dotted lines showing the same in their raised or separated position.

Similar letters refer to similar parts throughout the views.

Upon the base II, which may be of wood, metal, or any desirable material, I erect the opposite and parallel upright frames A, wide enough apart to allow the passage of the largest size of pail desired. In the top of A, on either side, are made the slots C, curved, as shown in the drawings, with the lowest point of the curves nearest the center of the frame, and just far enough apart to allow the rollers, when pressed together, to give the required wringing-pressure upon the mop-cloth. The central shafts of the parallel rollers B have their bearings in these guides C, and at their outer ends are pivoted to connectingbars E, which in turn are pivoted to the forked treadle D on either side, this treadle being pivoted in the upright of A farthest from the operator. The springs F on either side, which-may be made of metal or rubber, are attached to the top of the frame A and to the treadle D in such a way as to raise the treadle D and separate the rollers B when foot-pressure is removed from the toe-plate G of the treadle D.

The standard, as described, has a handle or bail I, by means of which it can be conveniently moved from place to place with or Without the pail K, as may be desired. K is therefore entirely free from any inconvenient attachment connected with the wringing mechanism, and may be moved for emptying or refilling by its handle or bail L Without additional weight or trouble.

The operation of my wring-er is best seen in Fig. 3, which shows the mop M as being drawn through the rollers B after they have been pressed together by the depression of the treadle. The handle M of the mop is shown away from the operator only for the convenience of the draftsman. It is evident that the handle H can be held by the operator and the wringing done without any inconvenience of position or loss of time. The shape of the guide-curves gives a firmer pressure of the rollers than could be obtained if the slots 0 were straight.

I am aware that prior to my invention inopwringers have been made to work by footpower. I therefore do not claim such a device, broadly; but

\Vhat I do claim as my invention, and desire to secure by Letters Patent, is-

1. In combination with the frame A, the

curved slots 0, lowest at their adjacent ends, as described, and acting as guides for the wringing-rollers B, when the shafts of the rollers are attached to the foot-treadle D by the connecting-bars E, as and for the purpose specified.

2. In a mop-wringer, the combination of the base H, the frame A, the guides G, the rollers 13, the bars E, the bifurcated treadle D, and the springs F, all arranged substau- 1o tially as described.

In testimony whereof I affix mysign ature in presence of two Witnesses.

CHARLES GILLMANN. Witnesses:
