PiPE, mum-Ron, AND CASING PULLER.

Too whom, it may concern Belt known that I, Josm'u' SAUL GEN- nnosga citizen of the United 'Statesfresidnods or casings-for permitting the North I)akota, ha\1e invented ,a new Pipe;

lh-ill-llod, andC asing Puller of .Whiclr the I following is a specification.

This invention relates to form of pipe. drill rod and casing puller or extractor,capable of-being easily and quicklyengaged with sections off-pipes, drill lifting or extracting of the same from theboflr and for 'allowing "the same. to b.e freel \7 rotated in order that the couplingsof other sections which may be engaged therewith and be disengaged therefromw Another "ai id equally i n'i portant object-of cthe 'inrention' is to proridei a dei'icefofthe character mentioned which when engaged with an object will have the line of pull directed -to the center of said object and as a consequence,"materiallyfacilitate the removal thereof,

' Applicatioii filed'Deceinber 26, 1917. Serial No. 208,891.

' The spaced sides of the iooped bed are otfset' as at 3, preferably at points intermediate the upper and lower ends, and as will be noted,"are spaced suflicie itly to allow the coupling element, which is of a diameter greater than the diameter of the pipe, drill rod or casing engaged thereby to pass therethrough andin this way cause said coupling element to be loosely seated on said segmental jaw-2.

The upper end of the looped body 1- is elf-settherefrom as at l and is arranged in \'ertic al al uenz' at with the center ofthe vjaw '2. 'l'len'cc, when a cable or like connection 5 is secured thereto and dis rendered taut to support the device. the resultant line fpilll or'drafi will be accurately ceiitere 'l' with respect to theccnter of the'jaw and the object engaged orresting thereon and to be lifted thereby.

From the foregoing, by those skilled in the artthat l have pro i'dcd an exceedingly sim-pleand efficient derice for use in lifting. removing ,or extract,- ing pipe's,' drill rods or casings from the bores of wells, the same by reason of its construction, being capable of being quickl) and readily engaged-with an'objcct. thus. rendering it desirable for use as a picking tool also. Further, due'tothe manner in which the device is engaged "with an object. sai i'l object can be freely rotated 'in the event that it ,is necessarv to disengage or uncouple to the particular embodiment chosen for illustration herein, nor-to the exactconstruction. arrangement and adaptation of parts shown and described, butl reserve the right to-makc an cluingcs illlll'tllttl'illlOllH that fairly fall within the spirit and scope of the invention. r r
