H.. cAvE MOP WR I NGER Sept. l5,

Filed Oct. 10, 1939 fill Patented Sept. 15, 1942 MOP WRINGER Henry Cave, Hartford, Conn., assignor to The Fuller Brush Company, Hartford, Conn., a corporation of Connecticut Application October 10, 1939, Serial No. 298,784

1 Claim.

My invention relates to that class of mop wringers that are manually operated to compress the mop material in the act of wringing a mop and particularly one attached to a handle, and an object of my invention, among others, is the production of a wringer of this type of simple and comparatively inexpensive construction and one that will produce extremely efficient results in the expulsion of water from the mop structure.

One form .of a mop wringer embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing, in which- Figure 1 is a front view of a mop wringer embodying my invention.

Figure 2 is an end view.

Figure 3 is a View in section on a plane denoted by the dotted line 3-3 of Fig. 1.

Figure 4 is a view illustrating the operation of the wringer in wringing a mop.

Figure 5 is an end View of the device as seen in Fig. 4.

Figure 6 is a front view of a wringer of a slightly modified form of construction.

The invention forming the subject matter of this application is an improvement on the wringer shown and described in my co-pending application filed March 24, 1938, of Serial Number 197,821, to which reference is hereby made for such information concerning the complete mop as may not appear herein. In both of the structures of these applications the wringer is preferably composed of wire with jaws for clamping the mop material between them with a handle in the form of a crank for winding the mop material into a roll for expelling water from the mop. In the use of these wringers I have found that if a gap is created between the clamping jaws or, in other words, if a hump or humps is or are formed on either or'both of the jaws, more water will be expelled than in structures having straight clamping jaws, and the present invention in one of its aspects embodies this feature.

As shown in the .accompanying drawing my improved mop wringer comprises a handle composed of two lengths of wire 8 and 9 formed from a single piece with a coil spring I0 joining them at the outer end of the handle, as shown in Figs. 1 and 4. The length 8' of this handle is straight and the length 9 is inwardly bent as at II for a purpose to be hereinafter described.

At the inner end of the handle the lengths 8 and 9 are bent lat angles of substantially 45, more or less, thereby constituting clamping jaws I2 and I3 each of which terminates at its outer end in a ring, said rings overlapping each other, as shown in Figs. 1 and 4. As hereinbefore mentioned I have found increased results to flow when these jaws, either or both, is or are provided with humps which are made of consider- 'able length and the jaws are therefore bowed as at I5, thereby creating a space I6 between them within which the mop material I1 is placed at the beginning of the wringing operation, such material being wound around the humps I5 as the mop is wrung. The jaws I2 and I3 are pref.. erably crossed as shown in Fig. 1 and the overlapping rings I4 prevent the j-aws from separating as they otherwise would do when pressure is placed upon the mop material when being wrung. The operation of wringing a mop is shown in Figs. 4 and 5 wherein the outer end of the mop material is placed between the jaws I2 and I3 and within and across the space I6, the action of the spring III pressing the jaws toward each other. The wringer now being turned with one hand grasping the handle 9 and the other hand grasping the handle I8 of the mop, the mop material is wound into a roll and by this grasping of the two handles a powerful leverage is obtained to produce a very tight roll and thereby expel a maximum amount of water from the roll,'and here is where the inward bend Il comes into play. The greatest leverage will of course be obtained by grasping the handle 9 as near its outer end as possible, and the bend II will cause the hand of the user to slip toward the end of the handle and the grasp of the hand at this end of the handle is thereby ensured.

That form of the wringer shown in Fig. 6 is quite similar to that above described with the exception that both members of the handle are straight and one of the jaws I9 only is provided with the bowed portion 20. The operation of wringing the mop is the same as hereinbefore described.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the bestembodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim:

A mop wringer including two lengths of wire iiexibly connected and extending in the same direction close enough to be grasped within one hand of the user for action as a handle, and jaw members projecting from both of said lengths as extensions thereof and at substantially right angles thereto in proximity to each other with the outer ends opening to receive a at mop entered edgewise into said opening to be Wound about said jaws for a wringing operation, said jaws being bowed outwardly from each other to form an opening gradually increasing in width from opposite ends of the bowed part toward the center, said bowed portion of each jaw crossing the bowed part of the other jaw near the ends of the opening formed by said bowed portions and for increased expulsion of liquid from the mop in a wringing operation, said opening being of a length substantially of the width of a mop to be received therein.

HENRY CAVE.
