ARTHUR \VILLIAM LEJVIS, OF BRADFORD, PENNSYLVANIA.
SOCKET FOR REMOVING TOOLS FROM OIL-WELLS.
SPECIFICATION forming part of Letters Patent No. 360,311, dated March 29, 1887.
To all whom, it may concern:
Be it known that I, ARTHUR WILLIAM LEWIS, of Bradford, in the county of MeKean and State of Pennsylvania, have invented certain new and useful Improvements in the Manufacture of Sockets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in the method of manufacturing sockets for removing tools or obstructions from oil, gas, or Artesian wells; and it consists in a socket made from a tube in which the grain of the metal extends at right angles to the length of said tube, so as to form the socket with the grain of the metal extending around its circumference, and having the pin or head welded to the socket, and the slips then attached to the tool thus formed, as will be more fully described hereinafter.
The object of my invention is to simplify and cheapeu the construction over the process heretofore employed for producing sockets by lessening the amount of metal used, doing away with all forging 011 the bowl and reins of said socket, and lessening the amount of lathe-work necessary to finish and complete the tool, and thus produce a lighter and stronger socket.
Figures 1, 2, 8, 4, and 5 are views illustrating the old method of making sockets for removing lost tools or obstructions from oil-wells. Fig. 6 is a view illustrating my method.
Heretofore in the manufacture of these sockets two reins, A, are drawn out from the bar-iron under the steanrhammer to the shape shown in Fig. 1, and then these reins are welded together, as shown in Fig. 2, so as to form the upper part of the bowl of the socket, the grain of the metal running lengthwise of the reins and the part of the bowl, as shown. To the part thus formed the head or pin 13 is Application filed August 14, 1886. Serial No.2l0,912.

welded, and to the upper part of the bowl are then butt-welded a number of rings, 0, in which the grain of the metal runs around their circumference. This socket thus produced has to be turned up and bored out in the lathe, milled, and the slips secured in place. Tools thus produced are expensive, because the welding must all be done by hand, the parts are not exact, and consequently a large amount of lathe-work has to be done to complete the tool. The bowl of the socket must be formed of welded rings, with the grain of the iron running around their circumference, for the reason that as soon as the slips take hold of the article to be removed from the well they pull down in their seats and wedge between said article and the walls of the bowl of the socket, thus having a tendency to split the socket open.
In forming my sockets I take a tube with the grain of the metal extending at an angle to its length, and of the right internal and external diameter for the bowl of the socket, and from this I cut the required length. As the grain of the metal extends around the socket, .and not lengthwise of it, when the strain exerted in removing the tool comes upon the socket, the tendency is to split the bowl. As the metal has sufficient cohesion where the grain extends around the circumference of the socket to prevent all possibility of splitting, no rings are necessary, and hence the socket is lighter, more easily constructed, and much cheaper than one constructed of forged castings having a series of rings buttwelded upon them.
My socket being formed from a single thickness of metal, which is of the necessary internal and external diameter, all necessity is done away with for handforging on the body, and with a great share of the lathe-work necessary to fit and finish a rough forging. Slots are cut in the sides of the socket thus formed, so as to receive the slips used in this couuec tiou.
In case it should not be desired to weld the pins or heads upon the sockets, the upper portion of the socket may be provided with a which is provided with a head or pin and slots 10 female thread, and then the pin screwed into to receive the slips, substantially as shown position. and described.
Having thus described my invention, I In testimony whereof I affix my signature in 5 claimpresence of two witnesses.
