PIPE CLEANER Filed Sept. 3, 1929 Fatented July 15, 1930 ANTON B. MENSING, OF NEW YORK, N. Y.

PIPE CLEANER Application filed September 3, 1929. Serial No. 389,966.

This invention relates to improvement in pipe cleaners of the reanier type, adapted for use in cleaning the bowl of smokers pipes, the object of the invention being the production of a pipe cleaner from a single piece of wire, with provision for scraping the inside of a pipe-bowl, and the invention consists in the construction as hereinafter described and particularly recited in the claims.

In the accompanying drawings:

Fig. 1 is a front view of a pipe cleaner constructed in accordance with my invention;

Fig. 2 is a side view of the same;

Fig. 3 is a sectional view on the line 8-3 of Fig. 1;

Fig. 4 is a front View illustrating a modified form of my invention;

Fig. 5 is a view, showing the cutting-members provided with two cutting-surfaces;

Fig. 6 is a View of the device, showing it provided with difierentially-shaped cuttingmembers; and

Fig. 7 is a front view of the device shown inserted into a pipe-bowl.

In carrying out my invention, I longitudinally how the central portion of a piece of wire to form a top-bar 10, or, instead of howing the central portion, it may be left straight, as shown in Fig. 4. From this bar 10, sections 11 and 12 extend downwardly across each other, thence upwardly forming cutters 13 and 14, thence upwardly toward the bar 10, below which the wires are crossed, forming a loop 15, and the ends 16 and 17 turned outwardly and passed on opposite sides of the bar 10. The cutting- sections 13 and 14 are shaped to form sharp cuttingedges 18, and the ends 16 and 17 are slightly flattened and reversely offset so as to ride over the bar 10.

Instead, however, of having these ends extend beyond the bar 10, they may rest thereon, as shown in Fig. 4 of the drawings, and instead of forming blade-like edges 18, the cutting- surfaces 13 and 14 may be serrated, as also shown in Fig. 4; or the cutting- sections 13 and 14 may be longitudinally-bowed to provide two or more cutting-edges 19, as shown in Fig. 5; or, instead of forming the cutting-portions of uniform shape, they may be differentially of the drawings.

bowed, as shown in Fig. 6

In any of the foregoing constructions, the cutting end of the device is inserted into a pipe-bowl 20, as shown in Fig. 7, and one lin er inserted into the loop 15, and the movement of this loop toward the bar 10 will tend to expand the cutting- sections 13 and 14 and force them against the inner walls of the pipe-bowl with such pressure as is necessary to clean the bowl.

As the loop 15 is moved outward, the ends 16 and 17 ride or bear upon the bar 10, so as to prevent twistlng.

I claim ward therefrom upward, whlch the wires forming and crossed, thence turned cutting-members from extend upward and crossed to form a loop, the ends of the wire extend ing into contact top-bar.

with opposite sides of the 3. A pipe cleaner formed from a single piece of wire and comprising a top-bar, reaches extending downward therefrom and crossed, thence turned upward, forming cutting-members, the edges of which are formed with cutting-edges, from which the wires extend upward and crossed to form a loop, the ends of the wire extending into contact with opposite sides of the top-bar.

In testimony whereof, I have signed this specification.

ANTON B. MENSING.
