Description
@timed EDVVABD GUILLOD, OF TITUSVILLE, PENNSYLVANIA, ASSIGNOR TO BRYAN, DILLINGIIAM, AND COMPANY.
Letters Patent No. 84,353, dated November 24, 1.868.
IMPROVEMENT 1N vDRILLINcarene.
To all whom 'it lina/y concern Be it known that I, 'EDWARD GUILLoD, ofthe city of Titusville, county of Crawford, and State of Penn- Sylvania, have invented a new and improved Mode of' Constructing Drilling-Jars, for use in oil and other oi steel.
artesian wells; and I do. hereby declare that the iole lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which forni a part of'this specification, and in which l similar letters represent similar parts in all the views.
In describing 'my invention, it is deemed unnecessary to narrate in detail the precise manner in which drilling-jars are used, and the severe strains to which they are at times subjected, as they have been used in drilling artesian wells for many years, and their uses and defects are familiar to all well-operators." The great desideratum in manufacturing jars is to get the largest possiblearea of wearing and striking-surfaces, without weakening the parts subjected to tensile strain, and, at the same time, to so construct the several parts of the jars -that those parts giving and receiving the blow may notbecoine burred or upset, and the jars thereby become inoperative.
The form of jar almost universally used heretofore,
is that known as the link-jar.
The size of the drills used in oil-wells seldom exceeds iive and a half inches, and the cross-sectional area of the drilling-jars must not extend outside of a circleof aboutfour and a half `inches diameter.
In the' ordinary link-jar, the entire inner workingsuriace of the head of the link receiving the blow cannot exceed one and a quarter inch square, or an available area of aboutone and a hali` square inch.
In the form of jars shown, I obtain, within the same arbitrary limits, a similarl striking-surface of about four square inches, without lessening the strength of theparts subjected to tensile strain, and, in this form of l jar, I make the several parts of wrought-iron and teel, combined in the peculiar manner hereinafter set orth.
I' deem the above explanation necessary for a correct understanding of my invention.
In the drawings- Figure l is a perspective view of the jars complete.
Figure 2 is a vertical section of the same.v
Figures 3 and 4 are transverse sections, taken on lines A Band G D.
The bright tints represent steel, and the darker tints.
screw-pin, as shown, for attaching the sinker-bar of the tools. l
I construct the several parts of the jars of wroughtiron and steel, inthe peculiar manner shown, andin the drawings the letter s designates the portions made In making the bolt B, I take a piecej of wroughtiron, say about one and three quarters inch diameter,
and weld steel around it to form the bolt-head b, the
steel encasing the wrought-iron bolt as far up as may lbe desirable toprotect its wearing-surface.
It will'thus be seen that the wrought-iron extends through the bolt-head b, but that the wearing and, striking-surfaces of the latter, as well as the wearing-l suri'ace of the bolt B, are of steel, the tensile strain being borne by both the wrought-iron and steel. The
upper end of the bolt, including the collar and screwv' pin, is of wrought-iron.
In constructing the link A, I make the upper portion of wrought-iron and steel, and the lower portion `entirely oi' wrought-iron, as shown.
It will be seen that the outeir' portion of the bars a u are of wrought-iron, they being lined with steel, s s.
The wrought-iron is carried over the outer portion vof the head ofthe link c, and the steel s is also carried over the inner portion of the same and around the bolt B, the underside of the 'link-head c, upon which the bolt-head b strikes, at each stroke ofthe drill, being oi' solid steel, asshown.
In working the metals of which the link A is to be made, I take a bar of steel and at bar of the best of wrought-iron, forge each of themv into the general the link, to and throughout the opposite bar, and the .blow from the bolt-head b is received upon the inner portion of the link-head, in a direction at or nearly at right angles to the fibres of the iron, thus insuring the greatest possible amount of strength and durability.
Having thus described my mode ofconstruction,
What I claim as my invention, and desire to secure by Letters Patent, is-
The within-described drilling-jars, consisting of a singlelink and bolt,`constructed of wrought-iron and steel, combined and applied substantially in the manner represented, and for the purposes set forth.
` EDWARD GUILLOD.
