Appiicaion inea Juiy 25,1891. sereine. 400.752. in@ model.) l
To @ZZ whom, it muy concern:
Be it known that I, ABRAHAM MARTIN, engineer, atv present residing at 1.92 Birch field Road, Birmingham, in the countyot Vv'arwick, England, have invented new and useful Improvements in the Manufacture of EX- plosive Proj ectiles, of which the following is a full, clear, and exact description.
My invention relates to the manufacture of explosive projectiles or shells; and the invention has for its object to provide in the base of the shell a screwed rocket for the fuse of suiiicient length to prevent the blowing out of the fuse and the consequent failure of the shell to burst under the force of the explosion. According to myinvention, the base-o the shell is formed by first screwing into the.
body of the shellA a ring or bush and then closingin or contracting the rear end of the shell behind or around the said ring or bush, which is thus imprisoned by the colitracted end ot` the shell, the closed-in base of the 'sheil and the internal ring or bush together, or the bush alone, as the case may be, ai'l'ording the necessary length ol socket l'or thc tuse.
Reference is to oe had to the accompanying drawings, i'oi'n'iing part ol` this spceilication, wherein- Figures 1,2, and illustrate by cenltral'transverse sections successive stages lof closing in the base wholly behind the internal ring or bush, thc fuse-socket being formed both in the turned-in portion and in the ring or bush. Figs. It, 5, and (i show the stages ot' closing in the shell behind a partially-coiled ring or bush in which alone the fuse-socket is formed. -Figs. T and S show a somewhat similar i'orm, the conical and closed-in portions being threaded.
The same letters of reference denote like parts in all the figures.
In either case the open cylindrical rear end o't' the shell A is cut with an internal screwthread a, in which the externally-'threaded steel ring or bush li is to be screwed.
In the example shown in l1`igs.1 to 3 the base end of the shell is screw-threaded internally for a sui'ticient distance, as shown ai u, to receive vthe ring or bush 'il and leave projecting suflieiently beyond said ring or bush the part c, which is to be closed in i ontracted, as hereinafter described. 'lhis part may either be iirst bored ont. sn'tieicntly to avoid the necessity ofscrew-threading it, or it may bc scre\\'-thrcaded along With ay and the screw-thread be afterward turned oit. The ring or busl1l3,l1avingits external cylindrical portion screw-threaded and the hole for the fuse lett plain, is then screwed home, and the part c ot the shell having been suiiiciently heated is placed, point downward, in a bed-die and subjected to the pressure of a closing-in die or succession of dies, by which the part c is brought to the form shown in Fig. 2 and finally to that shown, in Fig. 3, a central hole being preserved in the inwardlyturned end e by a central mandrel or core carried bvthc die. This hole extending through the ti ned-i n end ol the shell and also through the ring is afterward tapped,as shown in Fig. 3, to receive the l'use, the tota-l length of screw.- thread ed socket thus formed eonjointly by the ring and turned-in portion of the shell being" suliicicnt to prevent stripping` of the screwthread ol' thc fuse.
In the ease ol' a bushing 1i of the form shown in Figs. i, 5, and o its cylindrical part-is screw-threaded, as bclorc, but it is extended in the i'orm ol' a cone, so that the fuse-socket shall be i'ornied in the bushing' only. It is screwed into. thc shell, as bel'ore, and the part c ot' the latter is then heated and closed in around the `conical part of the bushing by dies, so'` as to imprison on the bushing, as shown i" Fig. 5, after which the Aexcess ot' the closed-in portion is turned' oil and the fusc- 1 socket, tapped to receive the fuse, as shown in Fig. (3.
In ligs. 7 and S the bushing is coned to a lesser degree and the conical as well as the" cylindrical portion is scrcw-threaded, the whole of thc-part of the shell which incloses the bushing being screw-threaded to correspond, so'that the thread ol the part c, when closed in, will engage with that of the conical part ol the bushing, as shown in Fig. S.
