OP-HEAD.

Specification of Letters Patent. Patented June 22, 1920.

Application filed October 24, 1919. Serial No. 333,072.

To all whom it may concern:

Be it known that I, WARREN B. BEAM, a citizen of the United States, residing at Mancelona, in the county of Antrim and State of Michigan, have invented certain new and useful Improvements in Mop- Heads, of which the following is a specification. I

My invention relates to improvements in mopheads, window cleaner heads, and kindred articles, and its object is to provide an implement of the kind named that may be made wholly of sheet metal and wholly by press and die work.

I attain this object by the construction shown in the accompanying drawing, in which Figure 1 is an elevation of the upper jaw of the head. Fig. 2 is a like view of the lower, or adjustable jaw of the head, and, Fig. 3 is a side elevation of the assembled implement.

Similar reference numerals indicate similar parts throughout the several views.

In the construction of these heads the back jaw or body is made of sheet metal of practically the form shownin Figs. 1,2 and 3, the jaw and the handle receptacle being made integral, and a hinge loop 2 being formed upon it and adapted to receive the hinge loop 2 on the'front jaw 3. The back jaw 3 has a right angled rim 4 formed at each edge of the head, struck inwardly from the inner surface, and a correspondin ri ht angled jaw rim 5 across the outer end he sides of the hinge loop-2 are far enough apart to easily receive the hinge'loop 2 and to form a perfectly working hinge, or pivotal joint between them, and they are pivotally connected by means of a proper pivotal connection, as the rivet 9. The front jaw 3 is formed with side edges folded down at right angles from the outer or front surface of the jaw, and with a clamping edge 5 turned in the opposite direction and in position to unite with the clamping edge 5 on the back jaw to form a complete clamping appliance toreceive and clamp a sponge,'as 10, or any other avail able form of fabric for cleaning, mopping, scrubbing, &c. 7

I provide for firmly clamping the jaws upon the element'lO, by means of a clamping bolt and nut 7-8. To insure the proper working of the bolt 7 I form a slotted aperture, 6, through the front jaw designed to give free lateral movement for the head of the bolt to compensate for the various relative positions of thetwo jaws, as, for instance, the jaws in their normal positions,

indicated by their solid lines in Fig. 3, or

their open positions indicated by the dotted outlines of the pivotal jaw 4. The corresponding hole, 6, in the stationary jaw, 4 may be made round, as shown, or any other desirable form, as oblong like 6.

The object for forming the edge flanges 4 on the pivotal jaw 3, outwardly, is two fold; first, to provide a strongly resisting jaw, without the danger of the flanges 011 the two jaws coming together and preventing free access between the jaws at the edges; second, to so form the edges as to provide a very strong, lasting hinge flange at 2, and, third, to provide a means whereby the head of the bolt 7 may be utilized without danger of unduly exposing it, or of marring surfaces bein cleaned by contact with it.

What I claim as new in the art is In a sheet metal mop head, a stationary jaw, a handle socket and hinge wings made integral, the edges of said jaw bent inwardly at right angles forming flanges, a pivotal jaw having side flanges turned outwardly at right angles with the jaw and'terminating in a two ply hinge element and the other end turned backwardly forming a flange corresponding with the end flan e on the stationary jaw, and a bolt passed through both jaws'and arranged for proper adjustment for opening and closing the jaws and securing them in desired positions for securing a fabric cleaning element.

Signed at Mancelona, Michigan, October WARREN B. BEAM.
