DIE FOR MAKING STEEL JARS. No. 311,648. Patented. Feb. 3, 1885 WITNESSES INVENTOR ATTORNEYS.
UNITED STATES PATENT OFFICE.
JAMES J. DAVIN, OF BRADFORD, PENNSYLVANIA.
DIE FOR MAKING STEEL JARS.
SPECIFICATION forming part of Letters Patent No. 311,648, dated February 3; 1885.
Application lilrd May 10, 1884. (Nu model.)
To (l/ZZ whom it may concern:
Be it known that 1, JAMES J. DAVIN, of Bradford, in the county of McKean and State of Pennsylvania, have invented a new and useful Improvement in Dies for Making Steel Jars, of which the following is a full, clear, and exact description.
Heretofore steel jars used in oil-wells between the sinker-bars and auger-stems have been made in parts and welded together, with the frequent result of burning and imperfect welds.
The object of my invention is to manufacto re these jars by forging from solid steel bars; and to that end I have devised the dies for striking the jars up by successive operations, as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is an end view of the die fitted with the cutters. Fig. 2 is an'interior face view of the same. Fig. 3 is a side view of one cutter, and Figs. 4 and 5 are similar views of a falling die. Fig. 6 is a side view, and Fig. 7 an end view, of the blank after being split, and Figs. 8 and 9 represent one half of the jar as completed.
A A are the main dies, recessed to the form required for the top, bottom, and sides of the jars. These are dovetailed to receive the portions that split and form the blank, so that the one pair of main dies A A may serve for both operations. The cutters a (shown in Figs. 1 and 3) have rounded forward ends and sharp cutting-edges, and they are of a width to nearly meet when the dies are closed. The fullers 0, Figs. 4 and 5, are wider, so as to separate the slit made by the cutter, and to round the inner edges.
In the first operation the solid bar of steel for the half-jar is operated upon and split to the form shown in Figs. 6 and 7, the cutting operation being commenced at the crotch. The cutters a are then removed from the main dies and the fullers I) inserted. 'lhese act to spread the slit and properly form the reins or slides d, as shown in Figs. 8 and 9. head 6 is afterward grooved, and the reins set out to the proper width by common pulleys. In these operations a narrow web of metal is left in the split, which (an be readily broken out, and thejars are then ready for being welded to the pin and socket picc:s by which they are to be connected in place. The jars made by these operations are of superior excellence, from the fact that not being welded at the crotch they will withstand the shocks without danger of splitting, which frequently occurs from imperfect welding.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The apparatus for making steel jars, consisting of main dies A A, fitted with cutters or fullers for cutting and shaping the reins, as specified.
2. The dies A A for forming steel jars, having removable central portions, or b, as and for the purpose specified.

It is hereby certified that in Letters Patent No. 311,648, granted February 3, 1885, upon the application of James J. Davin, of Bradford, Pennsylvania, for an improvement in Dies for Making Steel Jars, an error appears in line 51 of the printed specification requiring the following correction, viz: The word pulleys should be fullers and that the Letters Patent should be read with this correction therein to make it con form to the record of the case in the Patent Office.
Signed, countersigned, and sealed this 17th day of March, A. D. 1885.
