H. HERTZBERG WET MOP Filed March 19, 1928 HIS A TTORNEY Patented Nov. 12, 1929 HARRY HEBTZBERG, or BROOKLYN, NEW YORK wn'r MOP Application filed March 19, 1828. Serial No. 262,779.

This invention relates to mops and particularly to that type of such implements which are known as wet mops in which a plurality of mop cords or strings are t1ed together by suitable metallic clamping means.

It is the object of the present invention to provide novel means for clamping the mop material which will hold said material hrmly and secure the same resiliently on a mop l0 stick.

It is another object of the invention to provide a mop head which consists of two separate parts alike in form andconstruction for holding the mop material on the mop stick and for clamping it when in co-operatmg position. p

With these and other objects in new the invention consists of certain novel features of construction and arrangements of parts hereinafter more fully described and finally pointed out in theappended claims and lllustrated on the accompanying draw ngs Wh1ch form a material part of this appllcatlon and in which: I

Fig. 1 is a front elevation of a complete mop embodying my invention showing the mop holder members in place on a mop stick and clamping mop material.

Fig. 2 is a sectional elevation of Fig. 1 on line 22 of that figure. I I

Fig. 3 is a front elevation of the two mop holder members in the position they occupy when assembled into a mop as shown in Fig. 1. I 55 Fig. 4 is a side elevatlon of Fig. 3.

Fig. 5 is a top plan of Fig. 4. Fig. 6 is a front elevatlon of a single mop holder member.

Fig. 7 is a side elevation of Fig. 6 seen from the left side of that figure.

Fig. 8 is a top plan of Fig. 7

Fig. 9 shows the shape of a flat sheet metal plate before it is shaped into a mop holder member 11.

A complete mop which embodies my 1nvention consists of the mop material or cords 10, two mop holding and clamping members 11 which are exactly alike in form and construction and complemental to each other and 559 the mop stick 12 and two rivets 13. The mop hard sheet metal as steel or hard brass.

in a plane passing vertically through the axis of the mop stick, this plane is indicated on Figs. 135 68 and 9 by line a-a. From the shell portion downward a ban shaped portion 112 integral with 110 extends symmetrically on both sides of plane aa to a plane indicated by 0+0 in Figs. 4- 6-8- and 9. Below plane c--0 (see Fig. 9) the bar continues as 113 but is only of halfthe width of 112, it is located entirely to one side of plane aa and tapers towards its lower end. The bar 112 is curved towards a plane Z1b which passes perpendicular to plane aa through the axis of the mop stick (see Figs. 2 and 5) so that its end at 00 comes close to plane bb. The bar portion 113 is curved reversely into the form of a ring so that its end comes close to the curved portion of 112 (see Fig. 7). When two such members 11 are placed together so that their concave portions face each other, their ring portions 113 will lie close to each other to either side of plane a.a (see Fig. 3) one extending clockwise and the other counter-clockwise around the cylindrical space enclosed by them and together they encirclethis space completely as shown in Fig. 4. It can be seen that the two bars 113 cross each other at the plane 5-6 35 between the shoulders at 0(: of the bars 112. Figs. 1 and 2 show that the mop material 10 is clamped in 'the'ring formed by the circular portions 113 and that the semicylindrical parts lie against opposite sides of the mop stick 12and are held thereon by the rivets 13. Theiportions 112 ofthe clamping bars serve to hold the mop material a spaced distance from mop stick 12and form a resilient connection of the mop and mop stick produced 93 by the resiliency of the material inits curved shape. I I

In the manufacture of this mop two mop holding and clamping members 11 as shown in Figs. 5to 8 are first riveted to the mop 13) a in stick 12 whereby they assume the form shown in Figs. 3 to 5. The mop, cords cut to proper length are then strung through the ring portions 113 so that they extend an equal distance to either side therefrom, whereupon the ring portions 113 are further compressed against the mop-cords so that the material of he mop holder of that portion is stressed beyond its elastic limit and permanently deformed to grip the cords firmly.

lVhile I have shown this mop in its simplest form it is of course evident that the two parts ll can be termed integral with each other to form a tube around the mop stick and other c ianges may be made in its construction and arrangements of parts as come Within the scope of the invention defined in the claims Without departure from the spirit of the invention and the principle involved.

Having thus described my invention What 1 claim as new and desire to secure by Letters Patent is:

l. A mop comprising mop material, a pair of metallicbars holding said material, sai f bars forming separate units alike to each ring, means integral With each bar to align it with the other bar Whenin place on a mop stick and means fastening said aligning means to the sides of a mop stick preventing their transverse motion.

2. A mop comprising mop cords, a pair of metallic bars clamping said mop cords, means to fasten said bars to a mop stick each bar partly encircling said mop cords fo'rminga ring having an open gap said ring portions lying adjacent to each other extending in opposite directions away from said fastening means surrounding said cords, the gap in each ring being closed by the other ring and a projection on one side or" each barat the top of said ring overlapping the other bar 3. A mop comprising in combination, a mop handle, and mop material, a pair of bars struck from sheet metal surrounding said material, a plate integral with each bar and fastening means passing though said plate into said handle for its attachment thereto, said bars extending in opposite directions partly around said material and forming together a ring completely encircling said material.

i. A mop comprising mop cords, a pair of metallic bars surrounding said cords to form a mop, means adapted to fastensaid bars to a mop stick, each bar being curved to an S shape one loop of said $5 clamping said. mop cords and the other loop adjacent saidpfastening means comprising a connection of said mop to a mopistiok.

5. A mop comprising mop cords, a'pair of metallic bars surrounding said cords to form a mop, means integral with each bar to fasten it to a mop stick, each bar having the shape of an 8 one loop of said S clamping said mop cords and the other loop spacing said mop from said fastening means, the material of said spacing loop being of greater Width than that of said clamping loop providing a shoulder to support the clamping loop of the other bar. I

6. A mop comprising mop material, a mop stick and a pair of complemental members abutting against each other along two planes perpendicular to'each other passing longitudinally through the axis of said mop stick, a ring portion on each member partly encircling said mop material, said ringportions being oppositely disposed and adjacent to each other comprising means for clamping said mop material by completelysurrounding the same.

Signed at Brooklyn, in the county of Kings and State of New York this 12th day of March, A. D. 1928.
