snusa Filed April 14. 1930 Patented Oct. 6, 1931 UNITED STATES GUST H. VOIGT, OF HOLGATE, OHIO BRUSH Application filed April 14,

This invention relates to a brush Which is useful in Cleaning out sediment from Water pipes and the like, particularly around traps or other bends therein.

The object of the invention is to provide a brush having a long flexible shank, the portion of the shank near the handle being flexible to a lesser degree than the remaining portion. This S-ha-nk is preferably made from Strands of Wire tWined together.

The improved brush and the manner of making the same is illustrated in the accompanying drawings, in Which Figure l represents a plan view of the Wires 7 used in making the brush.

Fi lgure 2 is a similar view showing the handle and Shank of the brush partly made.

Figure 3 is a similar view of the completed brush. i

The brush Which constitutes the subject matter of the invention comprises bristles 5 Which may be of any suitable material and interwoven With the Wires constituting the end of the -shank in a manner to provide a brush of the requisite size and thickness.

The front portion 6 of the shank is quite flexible so that it Will follow the curvature of traps and other bends in the pipe When it is inserted therein. The rear portion 7 of the shank is also flexible but to a lesser degree than the front portion, so that it may be inserted in the more gradual bends of the pipe but Will not buckle under pressure Which is applied to advance the brush through the portion of the pipe to be cleaned. The rear end of the shank is formed With a loop 8 constituting a convenient handle by Which the brush may be nianipulated.

In the form illustrated in the drawings, the shank and handle of the brush are formed from two Wires 9 and 10, one of Which is considerably shorter than the other. In making the brush the middle portions of the Wires 9 and 10 are tWined about each other to form the loop 8. The Strands of the shorter Wire 9 are then twined about the Strands of the Wire 10, as shown in Figure 2, to form the stiffer portion 7 of the shank. The Strands of the Wire 10 Which then extend beyond the shank portion 7 are then twined about each 1930. Serial No. 444,019.

other to form the more fieXible portion 6 of the shank, the bristles 5 being intertwined With the extreme end portions of the Strands 10. A bead 11 is then secured to the end of the brush to facilitate the passage of the same over the irregularities in the internal surface of the pipe as the brush is inserted.

It Will be understood that the manner in Which the Wires are associated to form the shank and handle of the brush as Well as the dimensions of the different portions tliereof may be considerably Varied in accordance With the conditions under Which the brush is to be used. It is my intention, therefore, to include such Variations Within the scope of the appended claims.

What I claim is:

1. A brush comprising a plurality of bent Wires With their bight portions intertwined and forming a loop to constitute a handle, the remaining portion of each Wire being tWined to form a flexible shank With a part of the other Wire, and the last Wire being continued beyond the other to form a more fleXible shank portion, and bristles carried at the end of said last mentioned shank portion.

2. A brush comprising two bent Wires of unequal length With their bight portions intertwined and forming a loop to constitute a handle, the remaining end portions of the shorter Wire being both tWined about both Strands of the longer Wire, the latter beyond the ends of the shorter Wire being twined about each other, and bristles intertwined With the end portions of the longer Wire.

In testimony Whereof I have hereunto signed my namel to this specification.

GUST' H. VOIGT.
