Tools for Extracting Obstructions from Deep Wells] JAMES, H. LUTHER-,- or KAnNs orrY, rnnnsrnvn sm.
' IMPROVEMENT m TOOLS FOR' EXTRACTING ossrnucnous mom DEEPVWELLS.
' Specification forming part of Letters Patent No; 209.486, dated October 29,'1878 application filed r October 12, 1878.
To all whom it may concern? Be it known that I, Jsnrns H. LUTHER, of KarnsGity, in the county of Butler and State 'of Pennsylvania, have invented a new, and useful Improvement in Tools for-Extracting Obstructions fromDeep Wells; and I do here.
by declare the following to be afull, clear, andexact description thereof, reference being had to the accompanying drawings, forming part of this specification, in which-- 1 Figure 1 is asectional view of devices emdrills, and other like obstructions from deep wells, and isan improvementon Letters Batent No. 50,896, granted to William Bowden November 14, 1865.
It consists in the combination of an internally-tapered cylinder with a set of serrated wedges or wickers', the wedges being of such width and length that 'theycan-neither turn in the cylinder nor escape through the small opening thereof, while the diameter of the large opening of the cylinderis such as to admit the wedge or wedges, whereby a strong and ,ef--
fective tool is obtained.
The main object of the invention is to obtain such a construction. as will admit theuse of large and effective wickers, that are not liableto be lost in the well,-and to so construct the cylinder without weakening it that the wickers or wedges can, bereadilyinsertedand withdrawn. I
I will now proceed to describe my invention,
so that others skilled in theart to which it appertains may apply the same.
In the drawing, A represents a cylinder of suitable diameter, having an internal tapering:
cavity, terminatingin a contracted openingvor mouth, a, sufiiciently large to admit an end of any piece to be'extracted from the well. The
opening in the cylinder opposite mouth a is threaded for the attachment of a connectingpin, B, and is of such diameter as will admit readily a wedge or wicker of the desired size.
b breprefsent wickers or wedges whose taper corresponds to the. internal taper of'cylinder A, and whose bite, whe drawn together. is lessFt-han the bore of th cylinder. at a. The
length and width of these wedges are such that they cannot turn in the cylinder, and their greatest width slightly less than the threaded opening, so that while reatlily insertedjn the cylinder they cannotlescape at the mouth a thereof. Said wedgesane-serrated, as at c,
' whereby they are enabled to seize eitherarough or-smooth surface.
In order the bettpr to preserve the relation of the wickers and to insure their holdupon a smooth surface, such as a sniooth pin, a plate,
6, is placed over'the wickersand held in con-- 1 taetaiherewith by a coiled "dr other suitable r afv In constructing cylinder A, Lpreferably proceed as follows: Take a metal cylinder of the desired diameter-and length, and boreit out somewhat less than the size required for the moutlroa then here it from one end half'its length, -more;or less','to a diameter somewhat greater'thanfthe greatest width of the wicker or wedge to -be used, and thread the opening thusformed. Having secured the cylinderin a lathe,"turn down the interior of the cylinder from the mouth to the thread, giving such taper thereto as isdesired.
i The wedges arepreferablyformed from a v suitable piece of metal by boring. the same, cutting a thread therein, turning it to a suite ble taper, and dividing it into sections.
The devices-are employed as follows: The cylinder A, having been attached to suitable extensible connections, such as rods, pipes, or
drilling-tools, is lowered into the well until the obstruction is reached. The flare will direct or guidethe tool, so that any projecting part of the broken tool or substance tobe re- 1 moved will enter mouth a, forcing up and separating thewed-ges or wickers, which latter,
when trawtion ismade on cylinder A, will seize and hold the projecting portion of the article which is between them. Should the substance held between-gtlie wedges b b crush up or break off, there will be no liability of the wickers slipping thijoiigh the mouth a of the cylinder and belngliist unless the wicker-be actually crushed. If simplybrokemthe spring 2 menace will wedge the pieces so that they will remainin the cylinder.
Insneh cases as require it, a pin or projection will be milled or otherwise formed on the obstruction in manner and by means Well known in the trade; and the tool will be used with jars, and in every respect like similar tools now employed in removing obstructions from deep wells.
In describing one method of making the artiele, I do not Wish to be understood as limiting myself thereto,-as the skilled workman may select any other way he sees fit, provided he preserves the relative proportions of cylinder and wicker specified.
Having thus described the nature and advantages of my invention, what I "claim, and desire to secure by Letters Patent, is-- In a tool for extracting obstructions from deep wells, the combination of acylinder ha.v-
inga. tapered cavity with wickers of such width and length as will prevent their turning in the cylinder or escaping from the month thereof, substantially as described.
In testimony whereof I, the said J AMEB H. LUTHER, have hereunto set my hand. i
