To all whom t may concern:

Beit known that I, HERBERT A. VINING, a citizen of the United States, residing at Arlington, county of ,Middleseig Commonwealth of Massachusetts, `have invented certain new and'useful Improvement-sin Mops, of which the following is a specification.

This invention relates to mops, and particularlyto the mop head structure and the means for clamping the mop material to the mop head. i

The object of my invention is to provide a simple, inexpensive and attractively de# signed mop head and clamp for reliably clamping the mop material in place, so con* structed andarranged as to dispose the entire working face of the mop in a pla-ne parallel totheoor 0r other surfacebeing cleaned. This object and Certain other advantages which will appear more particularly hereinafter are secured in the device of the present invention, the construction and operation of which is fully explained in the specification which follows, illustrated f in the accompanying drawings, and particularly pointed out in the appended claims. rlhroughout the specification and drawings, like reference characters are correspondingly employed, and in the drawings Figure 1 is a top plan view of a mop head in accordance with my invention.

Fig. 2 is a bottom plan view thereof. Fig. 3 is a longitudinal section through the i mop head on theline of Fig. 2,-show ing in dotted lines the position of the clamp retaining fingers before clenching,a nd

y, Fig. l is a detail view'of the resilient mop material clamping member removed, the re` silient character of said member being indicated by the solid and dotted line showing.

I have indicated at 1 a mop head and at 2 any suitable mop material adapted to be clamped to said head.

According to this invention, the mop ma terial 2 is adapted to be clamped to the head 1 in such manner as to present a substantially flat working vface to the floor. Each individual strand of the mop material is therefore clamped to the head at substantially its center so that the strands are doubled upon themselves and have their free ends exposed as flat mopping surfaces.

As here shown the head 1 is of triangular shape and is so drawn orotherwise shaped as to slope downwardly in three directions Specification of Letters Patent. Pghtntdl Dig@ Application inea October 3i, i917. serial No. 199,543.

from its center producing yahead of general pyramidal form.` This construction provides an internal cavity in which a portion of the mop material may lie. The upwardly inclined seat l1` formed by the pyramidal shape of the head is cut out to receive agenerally sphericalsocket member or cup 3 which may be rigidly secured to the head 1 by `upsetting its inner end Vto form a flange i by means of which the cup may be soldered'to the internal face of the head. The

inclined seat l1 of the generally pyramidal headprovides for the connection of the han- `dle with the head at an angle,` whereby the i working face of the mop is disposed in a plane parallel to the floor or other surface to be inopped, and the entire working face of the mop thus exposed, whilethe handle itself extends at an oblique angle to the floor.

The handle `may be secured to the head by means of a bolt 5 set through the socket member or cup 3 at substantially right angles to the plane of the seat 11, and carries on its inner end a securing iiange 6 which may be curvedto conform to the curvature of the internal surface of the cup 3 and may be secured to the bolt within said cup `in y. a, iaiaj any suitable manner as by hammering over i the head of the bolt, (see Figs.` 2 and 3), The opening in the cup 3 through which the bolt 5 passes may be concealed by any suit-` able shield 61 whichis preferably run down upon the bolt until it abuts the socket ment ber 3 and there made fast to the bolt in any desired manner.

The mop material is adapted to be clamped tothe head lwithin the perimeter thereof and at the centers of the individual strands. For this purpose `the perimeter of the head is `bent downward to provide a substantially `vertical edge 7 against the inner face of` which the materialmay be clamped `by a clamping member 8 whichmay be held to the head internally thereof by a series of spaced depending lingers 9 formed `along the edge 7 (see dotted line showing Fig. 3), and adapted to be clenched down over the clamp' 8, (see solid line showing Fig. 3). The clamp `8 may be a simple wire bent to a substantially triangular form and adapted tof snugly lfit the internal face of the `head against the clamping edge 7 thereof. By making the clamp of resilient material (sec Fig. 4l) the operation of forcing the clamp toits seat 7 puts the clamp under tension and this tension not only assists te maintain the clamp in place due to the tendency of the wire to expand, but causes the wire to firmly clamp the-mop material between it and the edge 7 of the head. This clamping action is best illustrated in Fig. 2 wherein the mop material is shown as clamped at the centers of its individual strands between the clamping wire and the edge 7 of the head, and the retaining lingers are shown as bent down over the clamping wire.

It will thus be observed that the head l may be formed as a simple stamping into which the spherical cup 3 and bolt 5 may be readily set at the proper angle, and that the clamping member 8 readily seats within the vertically disposed edge 7 of the head and by reason of its resilient nature not only. tends to lodge itself therein, but acts to firmly clamp the mop material to the head.

Various modifications in the form and construction of my device may obviously be resorted to if within the limits of the apf pended claims.

What I therefore claim and desire to secure by Letters Patent is:

l. A triangular sheet metal mop head having a raised semispherical portion extending above 'the upper surface thereof, and a downwardly extending peripheral flange,` said semi-spherical portion constituting a seat for a handle connection, and a triangular shaped length of resilient wire expansibly lodged within said head and adapted to clamp strands of mop material against said flange.

2. A sheet metal mop head having a downwardly extending peripheral flange against the internal face of which strands of mop material are adapted to be clamped, and a resilient clamping member shaped to conform to the shape of said mop head at said flange, and adapted to be compressed and lodged within said head and tending when released t0 expand and clamp the mop material between itself and said flange.

3. A triangular sheet metal mop heald having a raised seat portion extending above the upper surface thereof and a downwardly f extending peripheral flange, the working face of the mop head being substantially flat, and said seat portion adapted to receive a handle connection, a triangular shaped. length of resilient wire expansibly lodged within said head and adapted to clamp the individual strands of a body of mop material at their centers between itself and the peripheral flange of the mop head, and fingers on said flange adapted to be clenched over said wire to retain it in place.

4. A sheet metal mop head having a downwardly extending peripheral flange against the internal face of which mop material is adapted to be clamped, and a length of resilient wire shaped to conform 'to the mop head at said flange and adapted to be compressed and lodged within said head and tending when released to expand and clamp the mop material between itself and said flange.

5.1i. mop head having a seat portion for a handle connection raised above the upper surface thereof and having a downwardly extending peripheral flange, against the internal face of which strands of mop material are adapted to be clamped, and a resilient clamping member shaped to conform to the shape of said mop head at said flange, and adapted to be compressed and lodged within said head and tending when released to expand and clamp the mop inaferial between itself and said flange.

In testimony whereof I aflix my signature in presence of ltwo witnesses.
