MMIII Illlwl UNITED STATES PATENT OFFICE.
JOEL KITSMILLER, OF CHICAGO, ILLINOIS.
TOOL FOR UPSETTINGENDS OF METAL TUBES.
SPECIFICATION formingk part of Letters Patent No. 472,504, dated April 5, 1892., Apnlication filed March 26, 1891. Serial No, 386,439. (o model.)
To all whom t vmay concern:
Be it known that I, JOEL KITSMILLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Tools for Upsetting Ends of Metal Tubes, of which the following is a specication.
My invention relates to the upsetting and thickening of gas and other pipes for various purposes, and particularly to such upsetting in the manufacture of tubular vdrilling-tools or drill-rods from gas-pipe or other malleable metal tubing. This tubing is used in sections adapted to be joined by screwing them together for the purpose of increasing the length of the tubular drill-rod, and this necessitates a screw-thread being cut upon the exterior or interior of the section of pipe at its ends. To avoid weakening the pipe by cutting the thread upon the pipe in its normal thickness the ends of the pipe are in practice upset and thickened to offer a heavier blank to the screw-cutting tools. It is desirable that the drill-rod to be constructed from these joints of pipe should be of an inner diameter sufiiciently great to allow a core to be formed within the tubular column and of an outer diameter but little less than the bore of the rotary drill which it follows. The diamonds or cutting-surfaces used in the drill are set to extend enough beyond the outer periphery of the drillingcolumn to give the drill clearance-way. This clearance-way must not be restricted or impinged upon. The tubular rods when upset must not, therefore, be increased in their outer diameter at the joints; but the thickening of the tubular rods at their ends must be toward the center of the rod, as shown at D of Figure 3, while the outer diameter remains the same to maintain the clearanceway aforesaid. The upsetting of these sections of pipe for this purpose has heretofore been done by frequent beatings and the use of several tools to effect the required result. To obviate the necessity of using so many tools and to save time in handling the same, and thus secure the upsetting of the tube more quickly and with fewer heats of the pipe, and consequently more cheaply than heretofore, I have invented an upsetting die or tool and method for upsetting such tubes, illustrated in the accompanying drawings, in which- Fig. l is a drawing of the die or tool. Fig. 2 shows the tool and pipe arranged under a steam-hammer ready to receive the upsetting-blow and shows in vertical section the operative parts of the die and a portion of 6o the tube. Fig. 3 represents the pipe and die in position after the blows have been delivered, showing the pipe upset to a distance from its end by the process. In performing the operation of upsetting 65 a pipe an anvil-block or table A may be provided, having a lower platform F upon which to rest the section of pipe to be treated and a way or channel A within which the pipe may be fixed in any suitable manner to 7o to receive the blow. The pipe is heated and so placed in position; but instead of using the several tools, as heretofore, I place my upsetting-die on the heated end of the tube. This die or tool ha a stem B, an annular wall O, secured to sasfmd adapted to fit snugly about the pipe D, which is to be upset and control its outer diameter by preventing the expansion thereof, and a formershank E, located within and concentric with 8o` the said annularwall and attached to said stem B and adapted to enter the pipe and at the same time prevent its collapse and govern and fix the inner diameter of the end of the upset rod. The blow is delivered upon the die or tool, and the tube is upset and its exterior and interior diameters controlled and xed by the single operation and the use of the single tool. By this means the operation of upsetting is performed with less labor, and 9o being more rapidly done greater advantage can be taken of a single heat, the pipe is upset for a longer distance without reheating than otherwise, and consequently more cheaply than heretofore, and the texture ot' 95 the metal is less liable to be impaired than by the frequent beatings of the earlier process.
What I claim as my invention, and desire to secure by Letters Patent, is
An upsetting tool or die for upsetting tubes of metal, constructed with a stem B, an anuulal1 wall C, secured to Jthe said stem, and I impact of lhe upsetting-blow, substantially a former-shank E, located Within and conas described and Shown. centric with the annular Wall and attached Y 1 t 1 to the said stem, all integrally united and JOEL KUSMILLLL' 5 adapted to mme together upon the tube to Wtnessess be upset and x its exterior and interior di- J.
