WILLIAM W. EASTMAN-ANDFRANIS B.` MADEN, 0F4 MEADVILLE,
. PENNSYLVANIA.
Letters Patent No. 104,945, dated July 5, 1870.
IMPROVEMENT IN JARS FOR WELL-DRILLS.
The Schedule referred to in these Letters Patent and making part of the same To whom it may concern:
Be it known that we, WILLIAM W. EASTMAN and FRANCIS B. MARDEN, of Meadville, in the county of Crawford and4 State of Pennsylvania, have invented a certain new and useful Improvement in a J ar for Drills for Oil-Vells; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing making a partof this specitication, in whichg Figure 1 represents a vertical section through (showing the drill-bar socket) tube in which the jarbar or plunger slides, the sheath or covering for the tube-packing and cap or collar for securing the upper end.
. Figure 2 shows an exterior view of the same.
Figure 3 shows a cross-section ata: x.
Figure 4 shows another below, at yy.
My invention relates to a cla-ss of machinery for boring or drilling oil-wells, and it consists iu the construction and combination of the socket, the sliding jar or plunger, thepacking-sleeve and casing,l all arranged to operate in the manner hereinafter. dcscribed.
The jar-socket Als constructed by welding two pieces of iron. or stee1 together at one end, tol form a tube' or socket, a, into which the auger-stem is seemed, the portion above the weld being formed into a tube, with a sulicient hollow space to receive the jar-har or plunger B, and allow it to slide up and down in the tube two or three inches, more or less, as may be desired.
The plunger B is -rnade larger than the stem or spindle. B', above it, and is provided withl lips, l1 b, `which slide in grooves d d in the socket A.
The lower end of the plunger is beveled where it strikes on the shoulder c c, which is beveled to correspond with it in the lower portion of the jar-socket A.
The shoulder e e above is also 'beveled where it strikes on corresponding beveled shoulders ff, in the upper portion of the socket, to lift the drill. g
Near the upper end of the socket A is a recess, t' i, in which apacking is secured, through which the stern 'or bar B' slides, so that no water or grit can get in from the top to obstruct the working of, the jar, the plunger apparatus` being provided with means at the top to attach the sinker-bar and rope-socket, in the ordinary manner.
`The tube A and plunger B being nicely tted to Work together, the plunger is inserted by springing apart the top of the tube, the packing being put round the stem and secured in the recess 't' t, when the halves are. brought together and are secured firmly by a sleeve, D, around the top.
The larger portion of the jar-socket A is covered by a sheath, E, which may be screwed into the sleeve D at the top, and held iirm'ly. by a piu or screw, h, pnt through below the jar-plunger. l
Long experience in drilling and boring oil-wells has demonstrated the fact that it is necessary to have the jar for working and loosening the drill down iu the bore or well, as near as they can be conveniently to the point, and it is also very necessary that the loose parts that form the jar be protected from grit and water getting in, to wear out the slide or links, or iu whatever way they are constructed. Grit and gravel getting in-very often stick and wedge the parts so that the jar will not operate, and the drill gets hung so fast that it cannot be extricated, and the well is lost after hundreds and sometimes thousands of dollars have been expended. y
By the jar-movement, constructed in themann'er above described, we purpose to obviate the diiliculties which have heretofore been experienced, and make the process of boring or drilling oil-wells easier, and much more certain of being completed with su'ccess.
What we claim as our invention, and desire to secure by Letters Patent, is
The jar-mechanismas constructed, consisting of the socket A, the sliding jar or plunger B, the packing it in the recess, the sleeve D, and sheath or casing E, all combined and arranged to operate in the manner herein described, and for the purpose specified.
. In testimony whereof we hereunto subscribe our names in the presence of- WILLIAM XV. EASTMAN.. FRANCIS B. MARDEN.
