Patented Apr. 30, 1935 UNITED STATES PATENT OFFICE MOP Conrad Fatland, Mount Prospect, Ill.

Application May 24, 1933, Serial No. 672,649

2 Claims. (Cl. 15-119) This invention relates to mops, and the object of the invention is to provide a simple and efioient combined. mop head and wringer, and one which allows the mop to be very conveniently removed from the head and replaced.

or the accompanying drawing, Fig. l is an elevation of the mop, which embodies features of my invention; Fig. 2 is a sectional view thereof along the line 2- of Fig. 1; Fig. 3 is a sectional view along the line 33 of Fig. 1.

The mop head comprises a yoke, consisting of two curved bars Ell which are suitably fastened to any ordinary form of handle H. The outer ends 39 of the bars provide bearings'for the rollers i2 and E3. These rollers may be of any suitable material and may be journaled in the outer ends of the bars it in any suitable manner. In order to provide for suitably pressing the rollers together for wringing or operating purposes, I provide a second yoke M which has openings in its arms through which the spindles iii of the roller :3 pass. These spindles also pass through slots it in the ends IQ of the yoke lil. Pins ll are fixed to one of the yokes; in this case, the yoke Hi; and these pins pass freely through openings in the bars lo; and springs l8 mounted on the pins continuously press the yoke l4 towards the roller it. As a consequence of this arrangement, the roller I3 is continuously pressed towards the roller l2 and the mop 213 is pressed between the two rollers. The compression of the springs l8 and the size of the slots iii are suitable for the purposes.

This application is a continuation in part of the Patent No. 1,966,890, issued to me July 1'7, 1934.

To secure maximum results in expelling water from the mop 20, it is essential that normally the rollers l2 and 13 shall compress the mop to the limit and that the arms l9 shall be prevented from being forced apart when the wringer is in use. Thereforain order to conveniently insert the mop or remove it from between the rollers when so compressed, and in order to prevent said arms from being forced apart, I provide an annular flange 23 on the outer end of each of the spindles 22 of the roller l2, and I form the openings 2! in the arms I9 large enough to allow said flanges to pass freely through and to permit lateral movement of said spindles 22. This arrangement makes both rollers movable longitudinally of the arms i9 sufiiciently for the purposes, and when one end of the roller 12 is pressed inwardly, so that the flange 23 registers with the opening 2!, the arm is can be bent outwardly passing the spindle 22, of the roller l2, out of the opening 2!, and the other end of the roller l2 can then be released by simply unhooking the flanged spindle 22 from its hearing.

The operation is reversed when inserting the roller. The roller is inserted by first hooking one of the flanged spindles into its opening 2! in one of the arms l9, bending the opposite arm l9 outwardly and pressing that end of the roller l2 into place so as to let the flange 23 of the spindle 22 pass through the associated opening 2!.

I claim as my invention:

1. A mop head wringer comprising a handle, a yoke-like pair of arms fixed to the handle, each arm having an outer and an inner opening adjacent its outer end, a pair of coacting rollers journaled in the respective outer and inner openings, the inner openings being elongated, and the outer openings being materially larger than the associated spindles, both rollers being movable longitudinally of the arms in the openings, resilient means normally pressing the inner roller towards the outer roller, a flange on the outer end of each of the spindles of the outer roller, each of said flanges having a lesser diameter than the diameter of its associated opening, said flanges being engaged to the outer surfaces of the associated arms when the outer roller is pressed outwardly by said resilient means to prevent the outward bending of the said arms in normal operation, one end of said outer roller being releasable by pressing it inwardly a distance slightly greater than the depth of the flange on its spindle and bending its associated arm outwardly, passing said spindle out of its bearing, and the other end of said roller then being releasable by unhooking its spindle from its bear- 2. A mop head wringer comprising a handle, a yoke-like pair of arms fixed to the handle, each arm having an outer and an inner opening adjacent its outer end, a pair of coacting rollers journaled in the respective outer and inner openings, the inner openings being elongated, the inner roller being movable longitudinally in the openings of its associated arms, resilient means normally pressing the inner roller towards the outer roller, one end of the outer roller being movable longitudinally in the opening of its associated arm, a flange on the outer end of the spindle of said outer roller end, said flange having a lesser diameter than the diameter of the associated opening, said flange being engaged to the outer surface of the associated arm when the outer roller is pressed outwardly by said resilient means to: prevent the outward bending of the said arm in normal operation, said end of said outer roller being releasable by pressing it inwardly a distance slightly greater than the depth of the flange on its spindle and bending the associated arm outwardly and passing said spindle out of its bearing.

CONRAD FATLAND.
