ALFRED J. BASSETT, 0F BBONXVILLE, NEW YORK.

SEWER-CLEANER.

Specification of Letters Patent.

Patented Apr. 23, 191%..

Application filed July 23, 1915. Serial No. 41,486.

Y '0 all whom it may concern:

Be it known that I, ALFRED J. BASSETT, a citizen of the United States, residing at- Bronxville, county of l/Vestchester, State of New York, have invented new and useful Improvements in Sewer-Cleaners, of which the following is a specification.

This invention relates to a device which is essentially adapted for cutting through any impediment or obstruction lodged in the interior of a drain or sewer pipe.

The object of the invention is to provide the implement with a plurality of radially positioned blades mounted between equallegged angle irons for giving transverse and lateral strength to the blades.

The novel features of the invention are more fully described in the following specification and claims and illustrated in the accompanying drawings in which:

Figure 1 represents a side elevation of the implement.

Fig. 2 is a detail view of a blade.

Fig. 3 is a transverse section of Fig. 1.

In this drawing is shown an implement equipped with a series of blades as which are arranged to radiate from the longitudinal axis of the tool. There are four of these blades shown and each blade has a sharp cutting edge 6 extending from the forward to the rear end of the device. The blades have curved ends 0 so that the sharp ends can be readily thrust into a root of a tree or other obstacle situated in the pipe.

The blades are mounted on holding members cl of angle iron with the legs thereofof the same dimensions and forming fixed angles. Each blade is fastened between the legs of the holders by means of a bolt 6 passing through holes located in the holder and slots 2' formed in the blade. A nut f is inserted on the threaded end of the bolt and when tightened will firmly clamp the blade between the opposing legs of two angular holders. As indicated in Fig. 1, one of the angle irons has extensions 9 at both ends forming an integral part of the iron and each lug is provided with a hole or eye it for attaching a rod or rope to manipulate the implement.

The blades when arranged on the angular holders form a cutting device with the axis as the center, so that the tool will approximately fit into the bore of a tubular object. The blades have their outer edges convexed longitudinally so as to give only one point of contact for each blade and excessive friction of the blades against the interior of the pipe is avoided.

As indicated in Fig. 2, the blade is shown provided with slots i whereby the blade can be moved relative to the holder when the nut is loosened, so that the same blades can be employed for different here pipes.

' It will be seen that inasmuch as the cutting blades a can be readily removed, the device can be made adjustable for various sized sewers by simply putting in wider, longer or shorter blades.

I claim:

1. A sewer cleaner comprising a series of L shaped holding members, a plurality of radially positioned blades each having a longitudinal convexed cutting edge, and bolts for fastening the blades between the legs of the holders.

2. A sewer cleaner comprising a series of l. shaped holding members one member hav ing an extension at both ends each end of which is provided with an eye, a plurality of radially positioned blades each having a longitudinal convexed cutting edge with. curved ends, and bolts for fastening the blades between the legs of the members.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ALFRED J. BASSETT.
