WELL-SHOOTING-TORPEDO APPARATUS.

Application filed July 5, 1921.

To all whom it may concern:

Be it known that I, ALBERT G. STooPs, a

citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and. useful Well-Shooting-Torpedo Apparatus-,-

ing generally of the character of that disclosed in Letters Patent, No. 1,382,395, granted June 21-, 1921, and in some respects an improvement on that apparatus.

An object of the invent-ion is to provide an improved torpedo shell which shall be so constructed as to not be liable to cause an explosion when being charged with an explosive such as nitro-glycerine, or to accidentally cause anexplosion when being lowered into a well.

Another object is to provide a torpedo shell which may be constructed at moderate cost and yet be strong and reliable and advantageously composed principally of nonmetallic material, so as to minimize the liability to cause accidental explosion -while permitting the shell to be quickly charged with an explosive. i

A further object is to provide a torpedo shell which shall be so constructed that when two or more small torpedoes are loweredinto a well of large diameter the tor= pedoes shall be prevented from passing or becoming located side by side in the well, but shall be compelled to remain. one above another in the well as intended.

A still further object is to provide an improved torpedo of the above-mentioned char acter which shall be so constructed as to permit the connection of an anchor either to the lower end or to the upper end thereof and which shall be strong, durable and eco-v nomical in use.

With the above-mentioned and other ob jects in view, the invention consists in a well-shooting-torpedohaving novel structural features and improved parts, and in the combinations and arrangements of parts Serial No. 482,458.

as hereinafter particularly described and further set forth in the appended claims.

Referring to the drawings,Figure 1 is an elevation of the improved torpedo shell; Fig. 2 is a longitudinal central section of the improved shell as preferably constructed, more especially when required to be of large capacity and size; Fig.3 is a top plan of the preferred form of shell, partially broken away; Fig. 4 is a section on the line IV-IV in F 2; Fig. 5 is a top plan of a slightly modified form of structure comprised in the invention; Fig. 6 is a lon 'itudina'l central sectional elevation of t e modified structure; Fig. 7 is a fragmentary longitudinal central section showing a slightly modified upper portion of the shell; and, Fig. 8 ,is a fragmentary'longitudinal sectional elevation "showing slight modification of the lower portion of the shell structure.

In the various figures .of the drawings similar reference characters indicate like elements or features of construction herein referred to in detail. i

As preferably constructed the apparatus comprlses a hollow cylindrical body or shell part 1 which preferably is non-metallic and may be composed of fibrous material and suitably water-proofed, a bottom within the lower portion of. the shell, and a funnelshaped top inthe upper portion of the shell part. Preferably the bottom comprises a plug 2 which may be composed of wood or suitably treated fibrous substance, and is tightly secured in the. shell part by any suitable means, and the plug has a guide projection 3 integral therewith, in some cases the plug-part having a cavity 4 therein so as to be hollow and economical in the use of material while being of light weight, the guide projection having a tapering or conical guide surface 5. The guide .portion of the plug part has a base portion which is dlametrically larger than the exterior of the body part 1 so as to form a projecting safety guard 6 to slide in contact with the side wall of. the well boring, which may be jagged, to prevent the body or shell part coming in contact with the side-wall. The

back of the guard portion 6 preferably has 3 has a neck 9 integral'thereon to'be inserted in a hollow anchor 10 to reinforce and strengthen the anchor which may be suitably secured thereto, the anchor preferably having a flared portion 11 receiving the guide portion 3 and secured thereto by means of a nail 12. In some cases, especially in the construction of the larger sizes of torpedoes, the bottom part is provided with a longitudinal hole 13 in which a tie rod'14 is securedso as to extend partially through the shell part, the end of the rod being provided with an eye 15. Preferably the rod extends through the guide portion 3 and has a nut or head 16 thereon in engagement with the end ofthe guide. 1 I

The shellis provided with a top part 17 as preferably constructed that .is designed to permit of being cheaply produced of wood or suitable fibrous substance, and it has a flange 18 on its outerend that extends outwardly beyond the exterior of the shellto constitute a non-metallic guard. The back of the flange preferably has an annular groove 19 therein that receives the end of the body part 1. The top part is tightly secured by suitable means to the body part and has a funnel-shape a small outlet end 21 at the bottom of the top part. The top part is provided with means for suspending the torpedo which preferably comprises two

rods

22 and 23 embedded inthe top part and having

ears

24 and 25 thereon respectively to which a 'bail.26 is connected. A1 yoke is provided which preferably comprises

side rods

27 and 28 extending integrally from' the

rods

22 and 23 respectively and so as to be convergent each towards the other and having a loop 29 integral therewith-which is connected with the eye 15, whereby the bottom part is supported substantially by the 'bail.

' In some cases the tie rod may be omitted,

especially in construction of the smaller sizes of torpedoes, and the bail ears may be.

secured to the top part alone, in which case two

ear loops

30 and 31 are arranged upon the top part, the loop 30 being connected with

anchor rods

32 and 33 that extend downwardly in the top part, the loop 31 being connected with anchor rods 34 and 35 that extend downward divergently in the top part in suitable grooves in the exterior thereof, the rods 32 and 34 being connected with a horizontal rod 36, and the

rods

33 and 35 with a horizontal rod 37 so that the bail is strongly connected with the top part ofthe torpedo.

Itmay be desired in some cases to constru'ct the top art of the torpedo so as to be of light weight, and in such event, the

upper portion of the body part 1 has a metallic thimble or liner 38 secured therein which is provided with an inwardly extending flange 39 that is arranged on a planed inner side 20 with corresponding to the end of the. body part.

'-A metallic funnel 40 is arranged within the thimble and has a flange 41 on its upper larger portion and extendingover the flange 39 and against the end of the body part, and the-flange has a bead 42 on its edge part.

When it is designed to use torpedoes of small diameter in a well of considerably ,largerdiameter inwhich two of the torpedoes might be received side by side, the torpedo is provided with means whereby to artificially augment the external diameter thereof to prevent the torpedoes from slipping out of'proper place one above the other; To th1s end a plurality of rings, which may be cheaply composed of wood, are secured on the body part, one ring 45 being arranged behind the guard 6 and preferably having a. rounded or beveled lower. edge 46, and another ring 47 is arranged adjacent to the guard 18 and likewise has: a rounded lower edge 48. The rings .-may, be placed tightly on the body part before the latter is secured to the bottom and top parts and may be cemented .or

otherwise secured to the body part. In practical use the torpedo properly charged with an explosive is lowered into a well by means of its bail and the lowering apparatus commonly used, the guards on the torpedo preventing contact of the body part or' netallic parts of the torpedo with the metallic casing. in the welLor-with rough or jagged wall'portions in the wellbelow the casing. The guard rings afl'ord extra protection to the body portion of the torpedo when a torpedo is provided with them, and they so nearly fill the well transversely that one torpedo cannot pass another, but all are maintained nearlycentrally, so that a plain anchor on the bottom of one-torpedo may be readily guided-so that its lower end shall fairly enter the flmnel in the top of the lower torpedo. The torpedo is placed in the-proper position in the well and anchored as customarily and is vsuitably exploded at the proper time, in some cases it being necessary to, use several 'of the torpedoes to obtain the desired results.
