PROCESS OF FORMI NG WELL STBAINERS.
Application filed November other similar foreign material, due to the fact that the foreign material may easily be carried away by the fluid in the interior flowing from the constricted gap or opening toward the open interior.
It is an ob ect of my invention to provide a strainer wherein the straining openings are out directly in the well pipe and thereafter operated upon to constrict the outer side of the passage. It is desired that a screen of this desired formation of opening may be made with a minimum amount of operation upon the pipe, so that the strainer may be efiicient in construction and economical to manufacture.
Referring to the drawings herewith, Fig. 1
illustrates abroken side elevation of a strainer pipe, employing thereon my improved method of forming the strainer openings. 7 Fig. 2 is a broken transverse section on the plane 2-2 of Fig. 1. Fig. 3 is a small detail in transverse section of a pipe having a slightly modified form of opening. Fig. i is a perspective view of a tool which may be employed in finishing the strainer opening in the pipe. Llke numerals of reference are employed to designate like parts in all the views.
In the drawing, I have illustrated a short section of strainer pipe 1, which is adapted to be connected as a strainer to well pipe, said pipe havingopenings therein positioned in the pipe adjacent the producing stratum. I have shown this pipe as being slotted vertically, as seen in 2, with openings formed in the pipe from the outside thereof, said open ings being cut with parallel sides, the length of which may be greater on the outer face than on the inner.
It is contemplated that these openings, or slots, in the pipe will be formed by means of a milling cutter or by any other well known. means for cutting openings in pipes of this nature, and when said openings are formed by a milling cutter, the said openings will be of longer size on the outer face of the pipe.
Kin the ordinary steel pipe.

This .is due to the shape'of the milling cutter, shown in dotted lines at 3 in Fig. 1. hen the slots are thus cut in the pipe, it is contemplated that they will be cut in rows about the circumference of the pipe, the rows having the slots cut in aposition alternating with that of the cuts in the adjacent rows, so that the openings will be staggered, as shown in Fig. 1. Whilethis is a preferred method of cutting the slots, it is obvious that the invention is not confined to this sitioning of the openings.
particular polVhen the openings have thus been out the p1pe, the outer portion of the slotted opening will be upset preferably by a tool such as shown at 4, in Fig. 4. .This tool has a forward end 5 formed by faces inclined inwardly to form a blunt end. Centrally of this forward end of the tool is a forwardly extending lip 6, the purpose of which is to register the tool with the'opening 2 into which it is desired to fit. .This tool is fitted within an air hammer or other similar means of operating the same, and in operation the forward point 6. which is intendedt-o determine the width of the opening at its narrowest point, is fitted within the outer face of the slot, as shown in Fig.2. The operation of the tool will serve to work the metal on the outer face of the slot downwardly and inwardly against the forward lip 6 of the tool. The slots or openings will shortly have the appearance shown in Fig. 2, in which there is p a constricted opening 7,which diverges somewhat within the said opening, "and then has the parallel sides 8., as in the original slot. The straining openings may be thus formed interior of the slotted passage diverges from the constricted opening toward the interior of the pipe with comparative regularity.
, It will be noted that the pipe may be slotted I by my method in a most economical manner.
Slots in the pipe may be out from the outside with a minimum amount of manipulation and rapidly. When thus formed, the outer 7 portion of the openings may be constricted 5 strainer onenings Willl ie inderstdbd by tlicise skilled in the art withumv'flmtker descri ztion.
What I claim as newand tlfisfiretb pitect; by Letters Patent is:
