Jeans 1 Emm t F e s/m ILLINOIS- MOP-HEAD.

Specification of Letters Iatent.

Patented Oct. 1, 1918.

Application filed December 1, 1918. Serial No. 134,258.

To. all whom it may concern:

Be it known that I, James H. Bmmovno, a citizen of the United States, and resident of Chi ag i he un y of Coo n Sta of Illinois, have invented certain new and middle over and upon the frame, and

stitched between the fold of .a flexible woven fabric so loosely surrounding and free to turn and twist: on the frame that in operation the fibrous strands are forced u wcrdly into a matted mass, locked to tie frame, with the result that the effectiveness of the mop is accord ngly reduced,

As the construction of mop heads from wires ,above described is desirable notonly for cheapness of construction, lightness and durability, but that they yield "under pressure, require'less exertionand concentrated force for the operation of the mop, it is at Home apparent that a y means by wh c i is possible and practical for increasing effectiveness of the fibrous strands will be a substantial and material improvement in the mop art.

The prime object of my invention broadly stated is to provide the wire frame of a mop with means operatin to maintain the fibrous strands in su stantiall an outstretched position, prevent their matting and permanent retention within the confines of the frame, and thereby accordingly promote the effectiveness and usefulness of the li /lore specifically stated the object of my invention is a mop head consisting frame provided with means for s lfting the bending point of the fibrous strands in a plane below that occupied by the frame,

Another object of my invention is to provide-a means for shifting the bending pomt of the fibrous strands "as above stated, and which is adapted to provide a locking means for the free end of the wire of the frame and furthermoreif desired a yielding-supof a wireport for the base of the convolute forming the socket for the handle.

With these ends in View, my invention find emb d m n in. c ain fe ur s o novelty in the construction, combination and arrangement f p rts y which he ai ohi t and certa n the Obje s, ar at aine all as hereinafter fully de'scribed with referense to e comp ny g d a n and more particularly pointed ont in the'claims.

In said drawing:

Figure 1'il lustrate s a to plan view of a mop head and mop thereor, in which my invention finds its embodiment.

Fig. 2 is a fragmentary detail showing h ans for shi ng t bending lpei the fibrous strands below, outwardly from the pl ne of h frame. nd its ptabi y to form a fastening for the free end of the i of the fr m nd a support for th conv te forming the socket por i n therefor, andl Fig, 3 is a vertical section taken on the l ne '3;3 o Fig 2;

similar chara ters o re erence ndica e the same parts in the several figures of the drawing,

The wi f ame the con truc ion o th icon the correlate 6 o mi g a ocket fo the handle 7, and thebendin" of the free end 8 around a uort oa 0f the ,nm o ma it continuous, "are of the usual form and construction heretofore employed, as is also the looping of the fibrous strands 9 over the frame at their-middle, and securing them together by means of stitches 10 passing theretln'ough, and through a woven fabric 11 looped over the frame, andbetween the folds of which the fibrous strands are projected.

Projecting from the frame 4 is a flange 12 which may be of any suitable material, as

for example bars of bent wood sleeved on the frame, but preferably consists of a con tinuous strip of resilient sheet metal, the depending ends of which are brought together after being bent about the frame as indicated at 13, of a thickness and stiffness best adapted for the purposes of its use, and

, which owing to the bends therein conform in to the frame is fixed in its operative positlon so that the edge of the flan e will determinethe bending point of t e fibrous strands, and which as indicated in the drawing is substantially below the plane of the during the operation 0' the mop, owing to the fact that the stitches 10 are secured adjacent the edge of the flange.

One end 14 of the flange terminates at a point sli htl removed from the coils forming the 1am le socket, the other end 15 of which, however, preferably projects across the end of the convolute sufficiently to provide a seat for the convolute. To prevent the two members of the flange from spreading apart, they may be riveted together, but in practice their corners 16-16 are bent together over upon one of the surfaces of the flange, as shown in Fig. 2.

The end 15 of the flange may also be pro vided With a perforation 17 forming a lock for and through which to project the end of the bend in the frame, which is thereby made continuous and a rigid structure, especially when supplemented by the flange when formed as shown in Fig. 3.

As a further means for supporting the convolute, the free end of the frame is projected between coils nearthe bottom thereof as indicated at 18, but both this and the locking of the free end of the frame to the flange through the provision of a perforation therein are features which may be dis pensed with without a substantial departure from my invention, the essential feature of which resides in a flange secured in a fixed and non-rotatable position to and dependwlereby the bending point of the fibrous strands of a mop mounted thereon is low- Copies of this patent may be obtained metal surrounding below the wire frame of a mop head,

Having described my invention, What I claim and desire to secure by Letters Patent 1s:

1. A mop head, having a continuous frame, formed from a single piece of wire, a mop mounted thereon, and a substantially rigid stri) suspended from the frame for shifting the bending point to the fibrous strands of the mop to a plane substantially below the plane of said frame.

2. A mop head, having a continuous frame formed from a single piece of wire, a mop surrounding said frame, a metal flange suspended from the frame for shifting the bending point of the fibrous strands of the mop to a plane substantially below the plane of said frame.

3. A mop head, the frame of which is formed from a continuous piece of wire, a convolute for the handle continuous with said Wire, a mop surrounding said frame, and depending below'the same, a flange projecting below the frame, consisting of sheet and secured to the frame. I In witness whereof, I have hereunto set my hand and afiixed my seal, this 25th day of November, A. D. 1916.
