1 claim. (cl. iis-104.31y

erated by a single person for cleaning the drain pipe in a building. Y

Another object of the invention is the construction of a novel persuader that can be quickly applied to a snake, whereby the plumber can greatly increase the rotary movement of the.

snake for removing an obstruction in a drain pipe.

A still further object of the invention is the invention is the construction of an efcient apparatus wherein a novel persuader is employed in conjunction with a snake and an efficient handle for the removal of an obstruction in a drain pipe.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is an enlarged longitudinal sectional View of a drain pipe, showing in elevation an apparatus constructed in accordance with the present invention.

Figure 2 is a top plan View of the sectional persuader, while Figure 3 is a longitudinal, vertical, sectional view of the same.

Figure 4 is a transverse sectional view, taken on line 4-4, Fig. 2, and looking in the direction of the arrows.

Figure 5 is an enlarged sectional view, taken on line 5-5, Fig. 1, and looking in the direction .0f the arrows.

Referring to the drawings, in which the preferred embodiment of this invention is illustrated, I designates a drain pipe and 2 is the obstruction therein. Integral with the drain pipe I is a waste pipe 3, as well as a cleanout hub 4. A plug holder 5 is in the cleanout hub 4.

A coiled snake 6 is provided which has on its inner end a spiral 1.

The persuader 8 comprises a primary section 9 (Fig, 4) and an auxiliary section I0. Screw pins Il are threaded into the primary section 9. These pins have their inner ends smooth so that they will freely slide in the pin-receiving apertures` I2. These pins Il keep the two sections 9 and I0 in correct position for causing the screw threads I3 to register prior to threading the persuader 8 into the plug holder 5, Fig. 1. The surface of the outer end of the persuader 8 has fiat portions on its peripheral surface, so as to afford an excellent grip for a monkey wrench, or the like, when the operator is screwing the persuader into the plug holder 5. The persuader is grooved at I4, Fig. 3, to receive the coiled snake 6. These grooves I4 act similar to screw thread sockets.

On the outer end of the snake 6 these is formed an annular groove l5. A handle I6 is placed on the outer end of the snake 6 and a locking screw I'I is on the handle, whereby when screw I'I is screwed inwardly, the inner end of the screw will engage groove I5, and by tightening screw II, the handle can be held rigidly on snake 6. Interposed between the persuader 8 and the handle I6 is a free grip I8, which revolves on the snake 6. The handle I6 is provided with a stub shaft I9 that has on its outer end a head 20. On the stub shaft I9 is a free rolling grip 2|. To rotate the snake 6, the operator grasps the grip I8 with one hand and grip 2| with the other hand, and by rotating the handle I6, the snake can be either threaded into the drain pipe I or removed therefrom sufficiently to enable the plumber to easily remove the entire apparatus from its operating position.

In operation, the plumber or operator usually threads the snake into the drain pipe as far as they can easily do so, prior to applying the persuader 8 to the snake. Then when the movement becomes hard on the hands, the persuader 8, by reason of its sectional structure, can be clamped on the snake and then screwed into the plug holder 5. The handle structure can be also quickly attached to the snake. One operator can manipulate this apparatus and can secure excellent results.

By reason of the powerful rotary action that can be obtained, the snake will be forced past any obstruction in the drain pipe, thereby removing the obstruction and producing a clean drain pipe. The spiral I of the coiled snake Ii will efiiciently pass around corners and angles and bad spots in the drain pipe.

To remove the apparatus from its assembled position, Fig. 1, the screw I1 can be loosened, whereupon the handle structure can be quickly removed from the snake 6, and then the persuader 8 is removed from the plug holder 5, whereupon the interlocking sections can be quickly separated and then the snake 6 can be easily pulled out of the drain pipe. By the sim- 3 plicity of all of the parts mentioned, this removing of the apparatus can be quickly accomplished.

While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to onerskilled in the art to which this invention relates 'dur'- ing the extensive manufacture of the saine, and I, therefore, reserve the right to make such the scope of the appended claim.v

What I claim is: n v As a new article of maiiuatuie, a `ti'ifil "for 10, y changes or alterations as shall fairly fall within cleaning waste pipes, comprising a 'cylindrical "15 persuader of substantially the same thickness from end to end, said persuad'e'rliei diameti'ifcally split throughout its length and comprising a primary section and an auxiliary'seet'ioii, said sections provided with flat contacting faces the `greater part of theirfdianeter, fsaid aux iliary section provided Withtwo pin=receiving apertures, said primary section 'provided with two threaded apertures registering with sain Y pin-receiving apertures of said1auxiiisuy sentan, pins slidably mounted in said pin=receiving apertures 'andrthreaded at one of their 'outeriends in said threaded apertures, said persuader being externally screw-threaded o'neh'alf di its length, said persuaderheyonditsserew threads and at on'e'end having iiat portions-on its peripheral surface for receiving a monkey Wrench, said sections of said persuader being helica-lly grooved internally throughout their lengths to act similar to screw thread sockets. a coiled snake threaded through said persuader and in engagement with said sockets, and a handle secured to the outer end of said snake.
