(Cl. 10B-60) 6 Claims.
The invention relates to tracers used in connection with antieaircrait projectiles for tracing their trajectories, and its aims to generally improve upon the construction disclosed in my U. S. Patent No. 1,518,247, issued December 9, 1924, on a .so-called Tracer fuse.
in carrying out the above end, a further object is to provide a cup attached to the body of the device and eiective to confine the booster charge and to also close the opening in which the interrupter of the firing train is mounted.
A still further object is to provide a novel structure and association of parts for normally holding the interruptor in unarmed position and for holding it against rotation.
Another aim is to make novel provision for holding the tracer charge in the body and insuring proper igniting, and burning thereof during flight.
Yet another object is to provide an improved construction insuring that the tracer charge shall invariably ignite the detonator.
A still further aim is to provide a novel construction in which the explosive charge in the projectile or shell may surround the booster charge to insure greater destruction of the entire assemblage if it fails to strike the target.
With the foregoing and minor objects in view,
the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.
Figure 1 is a longitudinal sectional View partly in elevation showing the association of the invention with a shell case, a shell or projectile, and a supersensitive percussion fuze.
Figure 2 is an enlarged longitudinal sectional vieu7 through the tracer and self-destroying device.
Figure 3 is a transverse sectional View on line 3-3 of Fig. 2.
A construction has been illustrated which has proven to be highly advantageous from numerous standpoints, and while said construction will be speciiically explained, it is to be understood that min-cr variations may be made within the scope of the invention as claimed.
A shell case 5 has been shown connected with a shell or projectile 5 having a supersensitive percussion fuze 'I at its nose, the explosive charge of said shell or projectile being denoted at 8. The improved tracer and self -destroying device 9 is carried by the rear end of the shell or projectile 8, is effective to trace the trajectory of Said shell or projectile, and is also effective to iire the charge 8 in case the fuze does not fire same by striking the target. It is thus insured that the assemblage shall be so destroyed in the air that little if any injury can be caused by falling fragments.
The tracer and self-destroying device 9 includes an elongated body I0 having an intermediate portion El of relatively large diameter, a rear portion I2 of smaller diameter, and a front portion E3 which is also of smaller diameter, said portion il being provided with external screw threads ifs to be threaded into the rear end of the shell or projectile 6.
The body I0 is provided with a socket I5 formed principally in the reduced rear portion I2 but also extending somewhat into the intermediate portion Il, said socket i5 having an enlarged rear end l, the inner wall of which constitutes a rearwardly facing shoulder Il. The socket I5 ccntains the tracer charge I8; a highly infiammable disk of thin sheet powder or other highly inflammable nitrocellulose compound lies against the rear end of the charge I5; and a Washer ring 2E! cf metal lies against the rear side of said disk IQ. This disk and washer ring are both located in the enlarged socket end I3 and they are held therein by an inwardly crimped flange 2l on the rear extremity of the body. By securing the tracer charge I3 in place in this manner, it is insured that it shall be properly ignited by the burning gases in the shell case 5 when the ammunition is fired, and it is insured also that said charge shall properly burn during night.
The reduced front portion i3 of the body IU is formed with a transverse diametrically extending opening 22 having an enlarged end 23, both ends of said opening being disposed at the periphery of said body portion I3, in the present disclosure. A longitudinal opening 24 extends from the opening 22 to the front end of the socket I 5 above described, and another central opening 25 extends from said opening 22 to a recess 25 formed in the front extremity of the reduced forward portion I3 of the body. The recess 26 contains a booster charge 21, and the openings 24 and 25 contain two of the elements 28 and 29 of a firing train extending from the tracer charge i3 to the booster charge 27, the third element 3i] of said train being carried by an interruptor SI which is slidable in the opening 22. The element 2S is an appropriate detonator, and the elements 29 and 3i! are leads of tetryl or other preferred material. The rear end of the detonator 28 projects beyond the opening 2li into the tracer charge I 3 and it is thus insured that said detonaabove described, thereby conning the inter-Y rupter 3| in said opening and protecting said interrupter.
The interrupter 3| is provided with an enlarged head in the enlarged end 23 of the opening 22, and said interrupter is formed with a central socket 36 which opens through the outer end of said head. A pin 3l' extends slidably into the outer end of the socket 36 and the outer extremity of said pin abuts the wall or sleeve 34, and a coiled compression spring 38 is housed Within said socket 36, said spring abutting the inner end of said socket and the inner end of said pin 3l. The spring thus acts to hold the detonator 3l in unarmed position but permits same to move to armed position under the action of centrifugal force.
The portion I3 of the body i6 is formed with a smaller opening 39 parallel with the opening 22 and opening into the enlarged end 23 of this opening, and the head 35 of the interrupter 3l is formed with an opening lill alined with said o-pening 39. A pin di is disposed in the two openings 39 and di) to hold the interrupter 3l against rotation, and the outer end of this pin abuts the sleeve or wall 34, being held in operative position by means of said sleeve or wall.
Opposite sides of the interrupter 3l are preferably milled off as seen at li2 in Fig. 3, relieving some of the weight at one side of the axis of the device to insure proper movement of the interrupter to armed position under the action of centrifugal force.
When the projectile B with the nose 'l and the device 9 are fired from a gun, the tracer charge I8 is ignited by means of the highly inflammable disk I9 which is in turn ignited from the hot gases within the gun. If the projectile strikes a target, the supersensitive iuze 'l' iires the explosive charge 8. If the projectile misses the target,
however, the burning tracer charge l ignites the detonator 23 and the latter ignites the leads 30 and 29, thereby firing the booster charge 2l which in turn res the explosive charge 8 of the projectile. Due to the novel construction employed, the forward portion of the body i0 and the sleeve or wall 34 are well within or surrounded by the explosive charge 8, insuring more thorough destruction o the assemblage and materially lessening the danger of anyone on the ground being injured from falling fragments.
Except, for explosive or inflammable elements, suitable metal construction is employed throughout and I have found that a hard steel alloy, when used in constructing the interrupter 3|, will prevent the detonator wave from being transmitted to the element 29 and the booster charge 2l, should the detonator 2B re prematurely from any cause.
Excellent results are obtainable from the exact details and proportions herein disclosed and I, therefore, prefer to follow same. However, attention is again invited to the possibility of making variations within the scope of the invention as claimed.
