MOP WRI NGER Filed Dec, 5. 1952 I 30 3 "Ill" 50 INVE NTOR- 4am Merger:
W-YLAW ATTORNEYS Patented Apr. 17, 1934 iJNiT STATES Tar 10 Claims.
This invention relates to improvements in mop wringers of a class adapted to be supported by a pail or bucket and the floor upon which the bucket rests, without being secured to the bucket. This application covers an improvement over the invention covered by my application Ser. No. 563,032 filed September 16, 1931.
One of the objects of my present invention is to provide a mop wringer wherein the force cmployed to squeeze or wring out a mop is adapted to be applied through pressure directed substantially downward at a point between the supporting floor and bucket.
Another object is to construct such a wringer so that an operator may stand on it to exert the maximum available wringing pressure without danger of moving or upsetting the bucket notwithstanding said bucket is not secured to the floor and the wringer is not secured to the bucket.
Another object of the invention is to provide a device of this kind in which the application of great wringing pressure may be applied to a mop through a pair of wringer rollers and the mop withdrawn therefrom without tending to slide the bucket along the floor or upset the same.
Another object of my invention is to provide a device in which the wringing rollers are adapted to stop short of contacting with one another when they are pressed into wringing position and prevent the mop from being immovably clamped between the rollers.
Another object of the invention is to provide a device of the class described with means for varying the wringing position of the rollers with respect to each other according to the thickness of the mop and prevent the wringing rollers from immovably clamping a mop between them.
Another object is to provide a mop wringer of the class described comprising treadle means for opening said device to receive a mop and treadle actuated cam means upon which an operator may stand to hold the wringer and bucket upon the floor to press the mop so that the same will be wrung out upon withdrawal therefrom, said cam means being adapted to limit the extent to which the device may be opened.
These and other objects of my invention will become apparent or be specifically referred to in connection with the following description of my invention and the drawing referred to there in, in which Figure 1 is a side elevation of my mop wringer with a mop inserted therein and showing the foot of an operator about to squeeze the mop between a pair of wringing rollers before wringing out the mop by the withdrawal thereof from between said rollers.
Figure 2 is a plan view of the device shown in Figure 1.
Figure 3 is an enlarged detailed view showing the manner of mounting the wringing rollers and the cam means for pressing the same together.
Figure 4 is a sectional view similar to that shown in .Figure 1 except that it incorporates a device adapted to limit the movement of the wringer rollers toward each other to accommodate a mop of larger size than that shown in Figure 1.
Figure 5 shows a fragmentary view of the wringer shown in Figure 1 and illustrates the manner in which the opening moveent of the devi e is limited by the cam means for closing the same.
Referring now to Figure 1, it will be seen that my mop wringer comprises a base frame 10, one end of which is adapted to restupon, and be supported by, rim 11 of a bucket or pail 12 and the other end is adapted to rest upon the floor or bucket supporting surface. In the embodiment of my invention illustrated in the accompanying drawing the frame 16 is essentially U-shaped with the closed end of the U, 13, adapted to rest upon the floor at a point somewhat removed from the bottom of the bucket. The sides 14 of the U- shaped frame 10 are formed to provide a horizontal portion 15 disposed between the closed end 13 and the bucket. At one end of the portion 15 the sides 14 are bent upwardly toward the top of the bucket forming side portions 16. These side portions 16 are bent inwardly at 1'7 and downwardly at 18 to form hooks adapted to extend into or hook onto the bucket to support the frame on the rim of the bucket. The side portions 16 are also formed to extend somewhat beyond the ends of the hooks 17-48 to afford supports 20 for a wring'er roller 21, adapted to be revolubly mounted on a roller shaft 22 carried by the supports. From Figure 2 it will be seen that the ends the supports 20 are disposed within the rim of the bucket and that the roller shaft 22 does not come in contact with the rim of the bucket. This arrangement insures that water which is wrung out of the mop by the action of the rollers, to be hereinafter described, will flow into the bucket. Moreover, inasmuch as there is no contact between the roller 21 or shaft 22 with the rim of the bucket, obviously any tendency to rotate the shaft 22 when the mop is withdrawn from between the rollers, as hereinafter described, will not cause the frame to move along the top of the bucket. A guard 23, having offset-s 24, is secured between the supports and adapted to serve the dual purpose of stiffening the sides 14 of the frame 10 to prevent the strands of the mop from becoming tangled or wound around the roller 21 when the mop is positioned against the roller and between the offsets 24.
Within the base frame 10 above described is a second frame 33, which, in the embodiment i1lustrated herein, is also substantially U-shaped. This frame is pivotally hinged or secured to the frame 10 at 31-31. The closed end of the frame 30 is designed to project a short distance beyond or behind the supporting end- 13, of the frame 10 to form a treadle 32 for rotating the frame 30 on the hinges 31-31 to open the wringer. Side pieces 33 of the frame 30 are formed somewhat similar to the side pieces 14 of the frame 10 above described, whereby the frame 30 is adapted to fit and move freely within the frame 10 about the pivots 31-31. The ends of the sides 33 are bent inwardly over the rim of the bucket at 34 and thence toward the roller supports 20 to provide supports 35 between which the second roller 36 is rotatably mounted on a shaft 37, carried by the supports 35. It will be seen from Figure 5 that when pressure is applied to the closed end or treadle 32 of the frame 30, preferably by the foot of the operator, the frame will be rotated and the roller 36 lifted through an are described about the pivots 31 and away from the roller 21 until such opening movement is arrested by the cam means to be hereinafter described. When the foot pressure is removed the frame 30 is adapted to fall by gravity toward the roller 21 and against a mop 38, as shown in Figure 1.. I also provide a stiffening brace 39 mounted between the open ends of the frame 30, to prevent the frame from spreading. The guard 23, in addition to the functions above described, serves also to stiffen the open ends of the frame 10.
I now provide a treadle actuated cam means for forcibly pressing the roller 36 toward the roller 21. This cam means comprises a pair of arms 40 pivoted by studs 41 to the frame 10 proximate the hooks 17--18 thereof. The arms 40 are formed to fit over studs 42 mounted on the side pieces 33 of the frame 30 and adapted to project generally to a position in front of the bucket and above the support 13, as shown in Figures 1 and 2. A treadle 43 is secured between the ends of the arms 40 remote from the studs 41 which secure the arms to the frame 10.
From the above the operation of my device will be readily understood by referring now to Figure 1 wherein the mop 38 is disposed between the rollers 21, 36, having been placed there by the operator after he had pressed downwardly on the end 32 to rock the frame 30 about the pivots 3131 and withdraw the roller 36 from the roller 21 sufficiently to permit said mop to be placed within the bucket against the roller 21 and between the offset portions 24 of ihe guard 23 whereupon the operator removes his foot from the end 32 to permit the frame 30 to drop by gravity against the mop. The operator is now able to apply pressure with his foot to the treadle 43 with the result that the arms 40 are rotated about the studs 41 and adapted through cooperation with the studs 42 to cam the frame 30 and roller 36 toward the roller 21 when the treadle 43 is moved to the position shown in dotted lines in Figure 1. It will be seen that the frames 10 and 30 above described are proportioned such that the operator may stand on the treadle 43 when it is in the lowermost, or dotted line, position and his weight will be disposed between the points where the hooks l7, l8 engage the rim of the bucket and the end 13 rests upon the floor. When in this position, standing on the treadle 43, the operator may then pull the mop from between the rollers 2136 to wring water from the same into the bucket. It will be observed that when the treadle is in its lowermost position it is disposed approximately midway between the horizontal portion 15 on the frame 10, and, in effect, forms a steady platform upon which the operator may safely stand without danger of upsetiing the bucket.
In Figure l I have illustrated a mechanism adapted to wring out a mop of medium size. In Figure 4, however, I provide means for wringing out a mop of larger size by preventing the treadle 43 from being pressed downwardly through its full stroke, so to speak. This means comprises a siop 45 mounted on the frame 10 and adapted to be elevated when it is desired to wring out a large mop and it is not necessary, and even undesirable, to bring the rollers 21 and 36 as close together as it is when a smaller mop is being wrung out. It will be seen from Figure 4 that in order to vary the space between the wringing rollers according to the size of the mop which it is desired to wring out the stops 45 may be elevated to limit the downward movement of the treadle, 1"
or turned downwardly to a position along the side of the frame 10, when it is desired to permit the treadle to move through its full stroke.
While I have described what now appears to me to be the preferred embodiment of my invention it should be understood that I regard the same as susceptible of modification without departing from the spirit of my invention or exceeding the scope of the appended claims.
