Application February 11, 1952, Serial No. 270,914

1 Claim. (Cl. 15-170) This invention relates to a broom construction.

An object of this invention is to provide in a broom an improved means for holding the straw strands together.

Another object of this invention is to provide in a broom, a split or two part band which is formed of metal or other suitable material for holding the straw strands or fibers together.

In the forming of a broom, while various types of machines have been designed for securing the straw together, in the final steps of binding the straw the usual procedure has been to manually stitch the strands together so as to form a binding band of thread or cord or to use a very expensive and complicated machine which reduces the manual labor to some extent. It is, therefore, an object of this invention to provide a straw holding means in the form of a split band having interlocking ends with pointed tangs on the inside of the band engageable between the straw to hold the straw from shifting and the bands from pulling out of straw, the band and the securing means therefor eliminating the usual stitching.

A further object of this invention is to provide in a broom a two part straw clamping band formed of interlocking means which may be stamped or otherwise formed at the ends of each with straw gripping tangs struck from or welded to the parts.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a detailed side elevaton partly broken away of a broom constructed according to an embodiment of this invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1 with the broom straw removed from the clamping bands.

Figure 3 is a fragmentary sectional view taken on the line 33 of Figure 1.

Figure 4 is a fragmentary sectional view taken on the line 44 of Figure 1.

Figure 5 is a fragmentary sectional view taken on the line 5--5 of Figure 4.

Figure 6 is a plan view of a modified form of clamping band structure.

Figure 7 is a fragmentary sectional view taken on the line 77 of Figure 6.

Figure 8 is a sectional view taken on the line 88 of Figure 7.

Referring to the drawings and first to Figures 1 to 5, inclusive, the numeral 15 designates generally a broom head which is secured in a conventional manner to a handle 16. In order to provide a means whereby the usual stitching of the strands forming the head which are :dis posed at a point below the handle 16 may be eliminated, I have provided a straw head clamping band generally designated as 17.

The band 17 is formed of complementary U-shaped members 18 and 19 which are adapted to engage about the head 15. The band or clamping member 18 is formed with locking teeth 20 at each end thereof and on the outer side of the member 18, whereas member 19 is formed with complementary locking teeth 21 on the inner side thereof which are adapted to interlock with the teeth 20. Each member 18 and 19 has projecting from the inner side thereof a plurality of pointed or substantially triangular tangs 22 which are formed along the edges thereof with outwardly inclined prongs 23. The prongs 23 on one edge of each tang 22 will be oppositely bent with respect to the prongs on the other edge of the tang so that the prongs on one edge of the tang 22 will interlock with adjacent straw fibers 24, as shown in Figure 4, whereas the prongs on the opposite edges of the tang 22 will interlock with other fibers which are positioned on the opposite face of the tang 22. These tangs 22 are preferably staggered and are bodily struck from the clamping members, as shown in Figures 1, 3 and 4.

Referring now to Figures 6, 7 and 8, there is disclosed a modified form of head clamping means embodying complementary substantially U-shaped clamping members 18a and 19a, which are formed with complementary and interengaging locking teeth 20a and 21a. Each clamping member 18a and 19a has welded or otherwise fixed to the inner side thereof pointed pins 25 which have struck along the length thereof oppositely bent locking prongs 26. The pins 25 on clamping member 18a are preferably staggered with respect to the same pins secured to and extending inwardly from clamping member 19a.

In the assembly of the broom head 15, the straw fibers 24 are grouped together in the normal manner and secured to the lower end of the handle 16. After the fibers have been secured to the handle 16, the fibers are then disposed between the complementary clamping members 18 and 19 whereupon these members are moved toward each other so that the locking teeth 20 and 21 carried by these clamping members will interengage and will thereby firmly and securely lock the clamping members 18 and 19 about the straw fibers.

As the clamping members 18 and 19 are pressed in wardly toward each other, the pronged tangs 22 will project into the head between groups of straw fibers 24 and the outwardly inclined prongs 23 will interlock with the fibers 24. These prongs 23 are adapted to hold the straw fibers in their initially assembled condition so that these fibers cannot shift within the clamping members 18 and 19 when the broom is in use and so the band will not pull out or off.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim is:

In a broom having a head comprised of a plurality of straws secured to a handle, a pair of complementary U- shaped clamping bands adapted to encompass said head transversely of said straws to bind said straws together, outwardly directed teeth formed on the outer face portions of the opposite ends of one of said bands, inwardly directed teeth formed on the inner face portions of the 3 4 opposite ends of the other of said bands, said outwardly References Cited in the file of this patent directed teeth being complementary to and interlocking with said inwardly directed teeth, a plurality of inwardly UNITED STATES PATENTS extending substantially triangular tangs struck from each 946234 Lay 1910 band, said tangs extending transversely of and at substan- 5 983053 Hobart et a1 31, 1911 tially right angles to said bands, and a plurality of out- 1,111,553 Althouse p 1914 wardly directed prongs struck from each of the opposite 1443811 Bowman 1923 side edges of each of said tangs and extending transversely 1,468,568 Jacobson P 1923 of said tangs, with the prongs struck from one side edge FOREIGN PATENTS bent oppositely to the prongs struck from the other side 10 494,911 Belgium Aug. 1, 1950 edge of said tang. 767,775 France May 7, 1934
