Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed June 22, 1906. Serial Ilto. 322.915.

To all whom it may concern:

Be it known that I, THEODORE Koorr, of No. 515 Western avenue, Milwaukee, Wisconsin, citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented cer- Pipeslools, of which the following is a specification.

This invention relates to improvements in tools" for removing obstructlons in sewer pipes, cisterns and other places where it is desirable or necessar to remove obstructions and which are inaccessible except for tools of comparatively small cross diameter and considerable length.

The especial object of the improvements I which form the subject matter of this application is to provide a tool that may be inserted in a drain pipe, cistern or the like,

-which may be used in grasping and 'With-.

drawing obstructions placed in such pipes and which may be'provided with lighting devices so that the obstructions may be seen by the operator while using the tool.

\Having these and other objects of general utility in view I have invented the device hereinafter described in detail and shown in the accompanying drawings, ,in which Figure 1 is a side elevation of the tool, and Fig. 2 is a rear elevation of the same tool in its inverted position.

Referring to the details of the drawing, 3 represents a wood star! or bar which may be of l any suitable len th and thickness. Se-

cured to one end'o this stafl by screws 5,

is a clasp composed of the back piece 4, and the clamping member 6 mounted on the back piece by pivot 7, and held under tension by the flat spring 8 one end of which is secured to one end of the staff. To the upper end 11 of the clamping member is secured a chain 9 which travels over a pulley 12 mounted in a suitable recess provided therefor in the stafi.

.The' upper endof the chain is secured to a staple 10 which is fixed in one side of the staff. Secured to the side of thestafl by screws 16 is a fiat metal plate 15 to one end of which is secured a socket 13" adapted to receive a candle'14. A similar plate 15 and socket 13 are secured at the opposite end of the stafi. and at this end, a hook 17 is secured by bolts 1.8.

To use a tool constructed substantiallv as described the end of the stafi on whic the clamp is mounted, is lowered into the pipe or cistern or other place from which it is desired to remove obstructions and if necessary, the candle I4 is lighted so that the operator can see the obstruction and then by pulling upwardly on the chain 9 open the clampmg end of the member 6, and thus grasp the obstruction, which is withdrawn raising the staff. If the obstructionis. I

Having thus described my invention What I claim, 1s:- I

1. A tool consisting of a staff, a hook secured at one end of said staff, a spring-held clamping device secured at the opposite end of said staff, and means for releasing said clamping device, said means comprising a chain and apulley onsaid Staff.

2. A tool consisting of a staff, a spring-held clamping device secured at one end of said stafi, means for operating said clamping dey vice, a hook secured to the-opposite end of said stafi', and means for roviding illumination adjacent to said-hook and clamping device respectively for the purpose described;

In testimony whereof-I affix my signature in presence of two witnesses.
