Definitions
- the invention relates to a shooting device particularly for explosive projectiles having a head fuse for instantaneous detonation, and to a device for adjusting the explosive projectile at will to instantaneous or delayed detonation, this shooting device being a tiring device or an explosive projectile with passive or active propulsion.
- Known projectiles of this kind contain in most cases a head fuse which can be adjusted at will to one of the kinds of detonation. The adjustment is then carried out immediately before the shooting by turning the head of a switch-over pin protruding from the circumference of the fuse casing.
- Projectiles of this kind are well suited for being loaded singly into the shooting device, i.e. for example into a gun barrel or a rocket projector tube.
- the shooting device i.e. for example into a gun barrel or a rocket projector tube.
- projectiles of the kind referred to are not convenient, when the inherently novel problem is set that their adjustment to instantaneous or delayed detonation is to be carried out without the projectiles having to be taken out of the magazine.
- a shooting device comprising in combination: an explosive projectile, a head fuse set for te States ate-nt MZZS Patented July 28 1964 HCC ing both said fuses operative and a second position put-N ting the said head fuse out of operation.
- I provide an explosive projectile, a head fuse set for instantaneous detonation upon impact tted to the head of said projectile, a percussion pin slidablyv mounted in the said head fuse, an impact head connected to the said percussion pin and protruding forward from said head fuse, inertia means in the transport condition of the said projectile locking the said head fuse in aA safety condition and upon tiring said projectile releasing the said head fuse to assume a cocked condition, the said impact head when moved back relative to the said head fuse in the safety condition thereof locking said percussion pin in the said safety condition even after having been cleared by the said inertia means, a control device having a first position clearing said impact head and a second position engaging and pushing back the said impact head before ring into the position locking said perc ussion pin, and a bottom fuse set for delayed detonatlon fitted to the bottom of said projectile.
- the shooting device may comprise a magazine, explosive projectiles each having a irst fuse set for instantaneous detonation upon impact and a second fuse set for delayed detonation upon impact, and control means arranged on the said magazine having a iirst position clearing the said projectiles and a second position engaging the said rst fuses of the said projectiles and putting the same out of operation after the final insertion of the said projectiles into the said magazine and prior to firing the same.
- FIGURE 1 is a longitudinal section of an explosive projectile
- FIGURES 2 andV 3 show a longitudinal section of the forward portion of a head fuse on a larger scale namely;
- FIGURE 2 in the safety position and FIGURE 3 is in the locked position;
- FIGURE 4 is a diagrammatic front elevation of a rocket projector device
- FIGURE 5 is a diagrammatic longitudinal part section on a larger scale of a rocket projector device on the line V-V of FIGURE 4.
- FIGURE l the shell of the projectile G is denoted by l, and the explosive charge by 2.
- a fuse 4 is built-in, and moreover into the bottom 3 a further fuse 5 is screwed, which extends intov the explosive charge 2.
- This bottom fuse 5 acts in a known manner accordingly not described in detail, so that after the impact of the projectile on the target the explosive charge 2 is detonated with a delay.
- a cylindrical body 7 is inserted in to the fuse casing denoted by 6.
- a groove 8 is cut in, wherein the detonator cap carrier 9 is slidably inserted and guided which carrier is designated as a prismatic slider.
- the axis of the detonator cap 1) inserted in a through-bore of the slider 9 lies outside the fuse axis and of the detonator core 11 forming the connection to a booster charge not shown in the drawings.
- the slider 9 biased by a spring 12 is retained in the safety position by a pin 13, which is partly shown only in the drawings, and which can be shifted back.
- the axis of the blind bore 14 co-incides in this position of the slider 9 with the fuse axis, and lies in the path of the percussion pin 15.
- the percussion pin 15, held by its collar 17 in the bore 18 of the fuse casing 6 is connected with the impact head 16.
- the latter protrudes ahead of the fuse casing 6 and is subject to the bias of a spring 20 abutting the plate 19.
- a pin 22 is slidably mounted in a transverse bore 21 of the casing machined at the level of the collar 117 of the percussion pin and issuing into the longitudinal bore 18.
- the inner cylindrical end 22a of this pin is forced by the spring 23 against the surface of the collar 17 of the percussion pin, while the other end 22b has a flange-like enlargement and protrudes into a groove 24 cut into the surface of the fuse casing 6.
- the cap 25 screwed on the fuse casing 6 protects the impact head 16 and the pin 22 in transport and when handling projectiles provided with such fuses from being actuated unintentionally.
- the caps 25 are unscrewed from the fuses and removed.
- the safety pin 13 moves back relative to the fuse body under the action of inertia, and releases the slider 9, whereafter the same is moved by the spring 12 into the cocked position, in which the detonator cap 1t) lies behind the tip ofthe percussion pin 15.
- the impact head 16 with the percussion pin 15 is thrown back into the detonator cap, whereby the explosive charge 2 is instantaneously detonated without delay.
- FIGS. 4 and 5 a rocket projector device is diagrammatically illustrated.
- the rocket motors R1, R2, R3 are diagrammatically illustrated.
- a control member in the form of a latch 30 with a handle 34 is articulated on two lugs 31 and 32 by means of a pin- 33 in such a manner that its rear end engages with an inclined face 30a into a slot 29 of the end wall 28.
- the latch 30 is retained in a first position indicated in FIG. 5 in full lines by means of a pin 35', which penetrates into corresponding bores of the lugs 31, 32 and through the latch 30.
- an essential feature of the explosive projectile and of the firing mechanism i.e., of the shooting device, consists in that the device for the adjusting of the device for instantaneous or delayed detonation is arranged frontally, while the handle 34 may however be connected to any device, in order to be able to perform the aforesaid re-adjustment from any other favourably positioned place.
- the invention is not, however, intended to be limited to this single embodiment. There are other possibilities ofrconstruction open to a person skilled in the art, of arranging the means for adjusting the explosive projectiles to the manner of detonation desired after their last insertion into the magazine. v
