  • INVENTORS HEINZ GAWLICK RUDOLF STAHLMANN BY @I ATTORNEYS SAFETY PROJECTILE PERCUSSION PRIMER BACKGROUND OF THE INVENTION It is known to provide a primer for a subcaliber training trench mortar with relatively axially movable firing pin and primer elements in an axially extending central bore of the projectile, which primer element has a primer composition for the ignition of the projectile charge. To prevent relative movements of the elements, a compression spring has been provided therebetween.
  • the primer element Upon impact of the projectile on the target, the primer element is forwardly displaced due to its inertia against the force of the compression spring for ignition upon engagement with the firing pin.
  • a strong compression spring is desired for safety reasons but yet is disadvantageous with respect to primer sensitivity upon striking the target; therefore, with low initial velocities, V,,, the primer may not be ignited upon striking the target and only limited safety is provided by the compression spring because of a compromise between the conflicting requirements of the spring.
  • the present invention relates to a percussion primer for rounds of ammunition to be shot from a barrel, particularly training ammunition for mortars, which primer is armed shortly after firing.
  • the two elements are retained in their unarmed spaced position by means of a locking member that is displaceably mounted in a radial bore of the projectile opening into the chamber; the locking member being in turn held in its interposed position by means of a safety member being in turn held in its interposed position by means of a safety member that radially abuts the locking member on the outside until after firing and the projectile leaves the barrel, which corresponds to movement of the safety member axially from its blocking position.
  • the locking member is constructed as a radially extending pin.
  • a spring is employed to urge the pin away from its locking position so that after it is released it will automatically move from between the elements to allow the displaceable one of the elements, the firing pin or the primer, to move axially under the effect of its inertia upon striking the target.
  • the front end wall of the cartridge case may be provided as the safety member, in accordance with the present invention.
  • the present invention may be used with a projectile that does not have a cartridge case, within the normal meaning of the term, but only has a bottom piece including the propellant charge; with such an arrangement, there is no front end of the cartridge case to serve as the safety member for holding the locking member.
  • a pin serves as the safety member and is axially displaceable in an axial blind bore rearwardly opening from the projectile body.
  • the safety member may be held in its locking position by means of an intennediate or spacer disc provided immediately adjacent the bottom of the projectile, which disc retains the safety pin in its locked position by axial abutment until the projectile and disc exit from the barrel at which time the disc will become separated and fall away from the projectile due to drag and the like to release the safety pin for rearward movement and subsequent release of the locking member to am the projectile primer.
  • the safety pin may be held in its locking position against the bias of a spring so that rearward movement of the safety pin to arm the projectile is assured.
  • the intermediate or spacer disc with a braking device, which will provide increased drag on the disc to assure its separation.
  • the braking device is preferably constructed of two radially retractable and expandable blades spring urged into their expanded position where they provide a braking effect on the disc shortly after exit of the projectile from the barrel and accordingly a serial release of the safety pin, locking member and displaceable element.
  • FIG. 1 is a cross-sectional view taken through the axis of a projectile employing a locking pin and contained within a cartridge case;
  • FIG. 2 is a similar cross-sectional view showing a modification of the FIG. 1 device
  • FIG. 3 is a partial cross-sectional view taken through the axis of another embodiment of the present invention employing a ball locking member
  • FIGS. 3a and 3b show modifications of elements of the FIG. 3 device
  • FIG. 4 is a cross-sectional view taken through the axis of a projectile and connected bottom piece according to a further embodiment of the present invention.
  • FIG. 5a is a cross-sectional view taken through the axis of the projectile at right angles to the view of FIG. 3;
  • FIG. 5b is a cross-sectional view at right angles to the axis of the FIG. 5a device.
  • the primer element comprising a primer composition and primer case
  • the projectile charge case 3 that encloses a smoke producing composition and within the axial bore or chamber 2 of the projectile 12.
  • the percussion firing pin 6 is fixedly secured to the projectile 12 at the front end of the bore 2 so that its firing pin tip extends rearwardly toward the relatively movable primer element 1.
  • a spacer compression spring 7 is provided between the front face of the bore 2 and the primer element 1.
  • a radial bore 8 or passageway is provided opening into the chamber 2 and slidably carries a locking pin or member 4 that is shown axially between the primer element and the firing pin element to prevent their relative displacement.
  • the locking pin 4 is held in its illustrated locking position against the force of the ejection spring 8a by the overlapping front end of the cartridge case 5 that radially engages the head 4b of the locking pin 4; in the illustrated locking position, the shaft of the pin 4 extends into the chamber 2 to block forward movement of the primer element 1 toward the firing pin element 6 to thus assure safety of the projectile primer during transport.
  • the projectile is provided with a propellant charge 9 that when ignited produces propellant gases, which will rupture the case surrounding the charge 9 and pass through the radial outlet openings 10 into the propellant gas pressure chamber 11.
  • the projectile With the buildup of pressure within the chamber 11 at the time of firing, the projectile will be forced forwardly out of the cartridge case 5 with the primer element being pressed rearwardly against the projectile charge within the casing 3 due to its inherent inertia caused by the acceleration of the projectile 12. Since the projectile l2 and the wall of the cartridge case 5 are not sealed off to be gastight with respect to the pressure chamber 11, the propellant gas pressure also becomes effective upon the head 4b of the locking pin 4 to press the locking pin 4 inwardly against the shoulder abutment 4a.
  • the length of the retaining path that is the path traveled by the projectile during which the locking pin is in its illustrated position, is depended upon the length of the barrel, on the one hand, and on the size and type of the propellant charge, on the other hand.
  • the length of this retaining path would correspond to the length of the firing barrel, thus ensuring the required barrel safety automatically.
  • the necessary barrel safety may be obtained in a simple manner merely by dimensioning the length of the locking pin 4 so that the pin 4 blocks the forward movement of the primer element 1 even when this pin 4 is pressed against the wall of the barrel under the effect of the ejection spring 8a. It is advantageous to construct the locking pin of a material substantially softer than the barrel wall to lessen the wear and tear on the barrel due to this sliding engagement.
  • the locking pin 4 is completely ejected from the radial bore 8 in all of the above cases by means of the compression spring 80, so that the primer body 1 is then free to move forwardly with respect to the firing pin element 6, that is, the projectile is armed.
  • this ejection of the locking pin 4- takes a finite amount of time so that arming of the projectile will only be accomplished at a distance from the muzzle of the of the barrel correlated in part to the initial velocity imparted to the projectile, which produces a desired and sometimes required safety of the projectile primer immediately in front of the barrel.
  • the primer element 1 Since the primer element 1 is mechanically blocked throughout substantially the entire travel of the projectile through the barrel, the undesired and unintended ignition of the projectile primer is safely avoided while a small relatively weak spacer spring 7 may be employed for increasing the sensitivity of the projectile ignition at the target. Thus, it is seen that the heretofore conflicting requirements of safety during transport and within the barrel and sensitivity at the target may independently be satisfied. With such a weak construction of the spacer spring 7, the primer element 1 will strike the firing pin 6 within a relatively short time and distance after the projectile strikes the target.
  • the device shown in FIG. 2 is identical with the device of FIG. 1, except for the differences to be described below.
  • the projectile 12 has a smaller diameter to the rear of the locking pin 4 so that the space immediately radially outward of the locking pin 4 is in direct free communication with the pressure chamber 11 to the rear. Accordingly, the pressure of the gases produced by the propellant charge 9 may readily become effective upon the head 4b of the locking pin 4 more rapidly and more uniformly than in the FIG. 1 arrangement.
  • the primer element 1 is provided with a primer charge and is fixedly mounted with respect to the projectile at the forward end of the chamber 2, and the firing pin element 6 is displaceably mounted in the rearward portion of the chamber 2 of the projectile.
  • the projectile 12 is mounted within the cartridge case 5, which case carries the propellant percussion cap 14 in its bottom piece 13 and forwardly thereof the propellant charge 15.
  • an intermediate or spacer disc 16 is provided in the bottom piece 13; an axially displaceable safety pin 18 is slidably mounted within the blind bore 17; the safety pin 18 rearwardly abuts against the spacer disc 16 and thus maintains the firing pin element 6 in its illustrated position by means of the interposed locking ball 19.
  • the projectile 12 with its primer element 1 and firing pin 6, and the spacer disc 16 are driven forwardly by the pressure of the propellant gases produced by the propellant charge 15; during this forward movement, the arrangement of the above-named elements is maintained as shown in FIG 3 until they leave the barrel of the firing device, not shown, that is, the safety pin 18 is retained in its blocking position by the disc 16 and accordingly the locking ball 19 and the firing pin 6 are likewise held in their locking position.
  • the gas pressure is suddenly decreased and the intennediate spacer disc 16 separates and falls away thus releasing the safety pin 18.
  • the thus-released safety pin 18 subsequently lags behind and separates from the projectile 12, because of the relatively larger mass, and to thus clear the path for radial outward movement of the ball 19 in the radial bore 8 of the projectile.
  • the firing pin 6 With radial outward movement of the ball 19, the firing pin 6 is also released so that it has complete freedom of axial movement for sliding forwardly in the chamber 2 by its won inertia upon the projectile l2 striking the target, which will ignite the charge of the primer element 1.
  • the safety pin 18 of FIG. 3 may be provided with a flangelike collar 18a at its rearward end.
  • the bore 17 is enlarged twice towards its rear to provide room for the ejection spring 20 that will ensure ejection of the safety pin 18 after the disc has fallen away to further improve the reliability of arming.
  • the modification illustrated in FIG. 3b also improves the arming of the FIG. 3 device.
  • the radial bore 8 is enlarged immediately radially outward of the locking ball 19 to prevent radial movement inwardly of the locking ball 19 in an undesired manner to its blocking position after the projectile has been armed.
  • FIG. 4 The device of FIG. 4 is similar to that shown in FIG. 3 and corresponding parts have been provided with corresponding numerals so that their specific description will be dispensed with, except for the differences.
  • the bottom piece 13 and the projectile 12 are connected together by means of the intermediate or spacer disc 16; thus, a cartridge case with a tubular casing is not needed.
  • intermediate disc 16 has a rearward extension 21 provided with one interlocking annular collar 22 that establishes a relatively weak connection between the intermediate disc 16 and the bottom piece 13. Also, the intermediate disc is provided with a forward extension 23 having three annular collars 24 providing a relatively strong connection between the disc 16 and the projectile 12.
  • the safety pin 18 extends through a bore 25 provided in the disc 16 and aligned with the bore 17 so that the safety pin rearwardly abuts against the bottom piece 13.
  • the annular bead 22 of the extension 21 is severed by the pressure of the propellant charge gases which develop; thus, the bottom piece 13 and the projectile 12 are separated from each other. Further, due to the pressure of the propellant gases, the projectile 12 together with the intermediate disc 16 is driven forwardly through the barrel (not shown) and the safety pin 18 is maintained in its locked position due to these pressure of the propellant gases. After exiting from the barrel, the intermediate disc 16 remains connected with the projectile and the safety pin 18 lags behind the projectile 13 due to its smaller mass so that it will rearwardly exit from the bore 25. Thereby, the locking ball 19 will be released to subsequently release the firing pin 6 to arm the projectile so that when the projectile 12 strikes the target, the primer element 1 may be ignited by the forward inertia movement of the firing pin 6.
  • the intermediate disc 16 is provided with a braking unit shown specifically in FIGS. 50 and 5b.
  • This braking unit comprises two opposed pistons 27 that are respectively rigidly connected with vanes or wings 26, with a compression spring 28 being disposed between the pistons 27.
  • FIGS. 3, 3a and 3b may be combined in a single device.
  • the spring urging feature of FIG. 3a may be used in the device of FIG. 4.
  • either the firing pin or the primer element may be the forwardmost os the two with the rearwardmost one being axially displaceable.
  • a projectile including a cartridge case consisting at least of a bottom piece, said projectile having a forward end; a
  • said locking member is a radially extending pin
  • said cartridge case telescopically receives said projectile therein and has a forward tubular wall portion constituting at least in part said safety member.
