ROBERT G. SANFORD, OF YONKERS, NEW yYORK.

PIPE-FISHING Toor..

Application filed October 24.

T o all whom 'it may concern:

Be it known that l, ROBRET G. Sauron-n, a citizen of the United States, and a resident of Yonkers, in the county of Westchester and State of New York, have invented a new and useful Improvement in Pipe- Fishing Tools, of which the following is a full, clear, and exact description.

My invention relates to that class ot tools that is-einployed to fish for pipes in Artesian wells, with a view to withdraw the pipes or other tubular objects contained in the well.

The purpose of. the invention isv to provide a very simple, durable, and economicil'orin of such tool and one that is under the complete control of the operatr at all times, and to so construct the tool that when it is introduced into a ipe and isdrawn up by means applied to itsy ody portion, the jaws carried by the body will practically sustain it and so grapple the interior of the pipe or tube as to carry thesaine upward with it.'

l't is also a purpose of the invention to pr`o vide means whereby should it be found inipossible to dislodge the pipe that the tool grapples, the

tool can loe quickly and converiently disconnected and withdrawn there- 'troiln without in any manner injuring the too..

The inventiony consists in the novel cion'- struction and combination of the' several parts as will be hereinafter fully set forth and pointed out in the claims. j

Reference is to be had to the accompanying drawings forming apart of this specication, in which similar charactersof reference 'indicate corresponding parts in both the views.

Figure 1 is a longitudinal section through a portion of the pipe and the improved 'lool contained therein, illustrating the tool ,in positive linesV as grappling the pipe and in Vdotted lines as release( thi; .'roin; and Fig. 2 is a lo 'tndinal edge view of the tool.

The ody' A ol" the device consists of two parallel side members 1() connected at the to y a cross bar 11 that maybe integral wit i said side members, the side members being connected at the bottom by a point 12, which. point is preferably solid, as is illustrated, and constitutes an integral portion of the ffitudinal body beopening or slot 13 is provided in th tween its side members 1G.

these bars are by preference rectangular iiiy y The

jaws

14 and 15 are i the bottom portion of the opening 13 and are connected preferably` cross section.

inks 2O are brought tovet er and are made to enter a longitudinal giet 22 inthe bottom ol" a block 23, that is mounted movement in the'space between of the body, and the said upper en( links 20 are pivoted to the said block 23 by.

the saine pivot pin 24. The block23 is limited in its movement b from side to side of the bor tudinal slot 26 -in the block, therefore block 23 can only move a distance corre*` is illustrated in `Fig. 1

The bottom wall 17 ot the openl end portion of the oint fc5- Y faces 17 give a slight upward inclination to when they extend out in for sliding the sides 10.. ls ofthe Sai: l:

If by any chance the jews should puncture tlie pipe, they may iossibly drop :it alright angle to tliefrene, but are held from drop# ping lower by their ettiiched linl'is. The device ,will ripZ a pipe anywhere iii its lengt-li,

.and 'the ievice can be lowered into it pipe when the latter is inclined, und the inoie thc,`
