To rill whom itmag/ concern:

Be it known that I, CHARLES MALCOLM KEnNnR, a citizen of the United States, and resident of Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Brooms, of which the following is a specification.

This invention relates to brooms and more particularly to the means to secure the handle to the head.

Briefly stated an important object of this invention is to provide a broom wherein a corrugated orthreaded tubular attaching member is embedded in the head and is firmly engaged by the stalks or strands constituting the head so that its accidental withdrawal is positively prevented.

A further object is to provide novel means whereby the forward portion of the handle is provided with threads adapted to engage the internal threads on the attaching member or sleeve.

A further object is to provide a broom which is of highly simplified construction, durable in use and cheap to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a fragmentary side elevation of the improved broom, parts being shown in section.

Figure 2 is a fragmentary group perspective of the same,

Figure 3 is a detail sectional view through the head of the broom and the attaching portion of the handle.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 5 generally designates the body portion of a broom, which body'porti on consists of a plurality of stalks or lengths firmly bound together at their rear ends by means of a binding wire 6 or the like.

In carrying out the invention a tubula member is designated by the numeral 8 and is provided with internal and external corrugations defining internal threads and defining external ribs 9 adapted for engagement bythe adj acent's'talks so'that the withdrawal or disconnection of the tubular. member 8 is positively prevented.

It will be seen with reference to Figure 3 that the binding wire 6 draws the stalks in the head 12 firmly into engagement with the external ribs 9 and in fact in engagement with the entire outer surface of the tubular member 8 so that the displacement of the tubular member is positively prevented. It might be said that an interlocking connection is provided between the external ribs 9 and the adjacent stalks of the head 12.

Figure 2 illustrates that the rear portion of the tubular member 8 is extended laterally to define a flange 14 which may extend over the adjacent portion of the cloth covering 16.

The outer edge portion of the cloth covering 15 is firmly held in position by the binding wire 6.

The handle is designated by the numeral 20 and has its forward portion formed with a spiral groove 22 to partially receive a spirally arrange-d attaching wire 24. That portion of the attaching wire 24 which is not received in the groove 22 constitutes a plurality of threads adapted to be received in the internal threads in the tubular member whereby a secure connection is provided between the handle and the body of the broom. The rear portion of the spirally arranged wire 24 is anchored to the adjacent portion of the handle by means of a fastening nail 26 and the forward portion of the spirally arranged wire may be extended through a transverse opening 29 in the for ward portion of the handle.

In use the handle 20 is threaded'into the tubular member 8 and the spirally arranged wire 24 is of course partially received in the spiral groove in the inner side of the tubular member. The frictional contact be tween the wire and the internal threads prevents the handle from being accidentally disconnected. Figure 3 illustrates that the broom handle 20 has frictional contact with the interior of the tubular member to coact with the wire 24 in holding the handle 20 against loosening.

A broom constructed in accordance with this invention may be economically manuends and urging the same into interlocking engagement with the external ribs on said tubular member, the outer end of the tubular member being extended beyond the stalk butts and formed with a laterally projecting annular flange, and a cloth covering extending over the butt ends of said stalks, said covering confinedat its center between said flange and the stalk butts and being held in position at its outer edge by said binding wire.

CHARLES M. KEENER.
