JOHN J. VVEINMANN, OF ST. PAUL, MINNESOTA.

MOP-PAIL WB/ING-ER.

Application filed April 4, 1923.

T (LZZ whom it may concern:

Be it known that I, J OHN J. Yz'nINMANN, citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Mop-Pail Wring ers, of which the following is a specification.

My invention relates to mop-wringers and the main objects are to provide an easily operated yet very efficient device of said kind.

in the accompanying drawing Fig. 1 is a top view of a pail, tilted slightly backward and equipped with my improved mop-wringer.

Fig. 2 is a front elevation of Fig. 1 with the pail not tilted and its bail omitted.

Fig. 3 is a rear elevation of a portion of Fig. 1, but the pail not tilted.

Fig. 1 is a side elevation looking as from left to right in Fig. 2, with the bail in place.

Referring to the drawing by reference numerals, 5 designates a scrubbing pail which may preferably be made of wood and have hoops 6 and a bail 7 pivoted at 8.

99 are two rollers arranged across the top of the pail and having their rear ends 10 journaled in the eyes 11 of a V-shaped spring 12 secured by a screw 13 and guided in a bracket 14 best shown in Fig. 3, and tending to force the rollers together. The front ends of the rollers are journaled at 15 in the upper ends of two flat bars 16, the lower ends of which are pivotally at tached to the upper ends of two operating rods 17 whose lower ends are pivotally connected at 18 to a foot lever composed of a pedal 19 and two curved arms 20 pivoted at 21 to the pail. The lever 1920 is normally held in raised position by one or more springs 22 in Fig. 4, or of any other suitable form.

The flat bars 16 are guided in a segmental yoke-shaped frame which may be either of cast iron or of flat bar iron and preferably composed of two flat bars 23-24 (see Fig. 1) secured together and to the pail by screws 2:3, 26, 27, 28, some of which have spacing collars 29 holding the plates properly spaced.

On the screws are pivoted the lower ends of two toggle links 30, having their upper ends pivoted at 31 to the upper portions of the bars 16.

Serial No. 629,947.

In the operation, when the bail 7 is folded backward upon the pail and the operator has used a mop on a floor and wishes to ing with the floor 38, so as to prevent tipping of the pail. Then he steps with his other foot on the lever 19. As lever 19 swings downward the bars 16 first glide on the screws or elements 28 so as to co-actwith rods 17 to cause both rollers to move toward each other. After the rollers have been thus guided the bars 16 leave the support or guidance at 28 and are now held in firm relation to each other by the toggle links until the latter are folded to the dotted position in Fig. 2, or nearly so, and thereby together with the spring 12, cause the rollers to come to about parallel position and to pinch the mop rag while the operator pulls it upward and may use it for mopping the floor as dry and clean as possible.

lVhen the lever 19 is released from the foot the spring 22 raises it and thereby causes the bars 16 and links 30 to spread the rollers t0 the position shown in Fig. 1 ready to receive and pinch the mop rag agaln.

What I claim is:

1. In a mop wringer, the combination with a pail, of rollers spaced slightly above the top of the pail, the rear ends of the rollers being journaled in bearings constantly spring-pressed toward each other, a frame secured upon the front side of the pail, a foot lever having spaced arms pivoted at opposite sides of the pail, a spring holding said lever normally in a raised position, journal bearings on the front ends of the rollers, and operative connection between said bearings and the foot lever, and means connected with the frame and outer bearing for automatically closing the rollers when the foot lever is pressed downward.

2. The structure specified in claim 1, said closing means being arranged to also guide the rollers in their movement.

3. In a mop wringer, the combination with a pail, of rollers spaced slightly above the top of the pail, the rear ends of the rollers being journaled in bearings constantly spring-pressed toward each other,

a frame secured upon the front side of the pail, a foot lever having spaced arins pivoted at opposite sides of the pail, a spring holding said lever normally in a raised position, journal hearings on the front ends of the rollers, an operative connection between said bearings and the foot lever, said operative connection and means for closing the rollers comprising two flat bars the upper entls oi? Which are normally spread apart and. formed with the bearing for the front ends of the rollers the lower ends of said bars lief g aperturerl and brought to a single center two rods having their upper encs pivotally engages in saicl aperture in the bars and their lower ends spread and pivotally attached to the foot lever, and tos' gle links connecting the upper portion or each of the flat bars to the frame.

4%. he structure specified in claim and obstructions on the pail for the outer edges of the inclined fiat bars to contact with during the sta t oi their downward movement, so as to get partly closed thereby until the toggle links get into position to complete said closing of the oars and t-herollers.

The structure specified in claim 3, the said frame he "T slotted and th said flat bars and toggle links moving in the slot of the frame.

In testimony whereof; l: atfir: signature.

JOHN J. lVElllMi-l fllli.
