MOP WRINGER, INCLUDING A SPRING URGED PRESSURE PLATE Filed May 12, 1947 Isabel M. Plamon don Patented Sept. 19, 1950 UNITED OFFICE OP WRIN'GER, INCLUDING A SPRING URGED rasssoas BLATE Isabel M. Plamondon, Goodrich, Mich. Application May 12, 1947, serial N6.747",42'5' 1 Claim. 1

This invention relates to new and useful improvements in mop wringers and the primary object of the present invention is to provide an attachment for pails including an open receptacle having a foraminous bottom wherein the mop head is securely held and a pressure plate carried by the bottom of said receptacle for bearing against the mop head.

Another important object of the present invention is to provide a novel support for the receptacle which is quickly and readily attached to a pail.

A still further purpose of the present invention is to provide a device of the character referred to which is small and compact for facility in use and transporting the same.

A still further object of the present invention is to provide a device of the class described which is simple and practical in construction, strong and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective view of the device in use;

Figure 2 is a top plan View of the receptacle and pressure plate, with parts of the latter broken away and shown in section;

Figure 3 is an end view in elevation of the receptacle and plate with parts broken away and shown in section;

Figure 4 is a vertical longitudinal sectional view of the device attached to a pail; and

Figure 5 is a perspective view of the receptacle supporting frame.

Numeral Ill represents an open receptacle generally preferably formed from a flat T-shaped blank, with one portion l2 of this blank provided with drain openings l4 and forming the bottom of the receptacle. The cross portion of the blank is folded upwardly to provide an end wall 16 with the free terminal portions of the end wall folded inwardly in alignment with the side edges of the bottom to provide side walls [8.

The end portion 20 of these side walls are folded inwardly and are secured as at 22 to the down turned edge 24 of the upwardly inclined portion 26 of bottom 12.

Carried by the bottom l2 are bolts 28 having upper eyes 30 and lower eyes 32 formed at their respective ends. A rod 34 is carried by eyes 30 and spaced from the bottom.

Suitably secured to rod 34 is a pressure plate 36 which is swung into and out of position with the bottom by a handle 38.

The lower end of bolts 28 extend downwardly past the bottom [2 and are connected. by a connecting rod 40. Coil springs 42 mounted on said bolts extend between the bottom l2 and the lower eye ends 32 of said bolts, for equalizing the pressure of plate 36, and to prevent tipping action of the pressure plate 36 relative to the bottom wall l2.

A supporting frame designated generally by the numeral 44 is preferably formed from a single length of iron rod and is adapted to support the receptacle in position to a pail or the like 46.

The frame comprises a pair of horizontally disposed parallel spaced arms 48 connected at their outer ends by a substantially U-shaped member 50 which bears against the outer side of the pail.

In the same vertical plane with arms 48 are pairs of parallel depending

inclined arms

52 and 54 having lower vertical portions 56 which bear against the inside of the pail, as more clearly shown in Figure 4 of the drawings.

In use of the device, the supporting frame is attached to the pail, as shown in Figure l of the drawings, and the receptacle supported on arms 48 of the frame.

The mop head (not shown) is placed on the bottom of the receptacle and the handle 58 of said mop head is extended outwardly between end portions 20 and above inclined portion 26.

By alternately raising the pressure plate to a position spaced parallel to the bottom l2 and pressing downwardly with the pressure plate 36 by handle 38 against said mop head,. any liquid contained in the mop head is forced through the bottom 12 of the receptacle and into the pail, see Fig. 4 of the drawing.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended c1a1m.

What I claim is:

A mop wringer comprising a receptacle having a perforated bottom wall, a pair of spaced parallel rods slidably carried by said bottom wall, a cross member connecting said rods, coil springs embracing said rods and biased between said bottom wall and said cross member for normally urging the cross member away from said bottom wall, a pivot pin carried by said rods and disposed within the receptacle, a pressure plate carried by said pin for pivotal movement relative to said bottom wall, and a handle carried by said pres-. sure plate, said springs being in tension during raising movement of said pressure plate to yield-'- ingly urge said pressure plate toward said bottom 16 Wall.
