Definitions

  • This invention relates to ordnance and particularly to firing pins for projectiles adapted to operate when the projectile strikes annloj-ect.
  • An object of this invention is to provide with which it coacts to fire the charge, noveljmeans being also provided for releasing the said firing p111 to permit its operation upon ⁇ impact of the projectile and the movement of the hammer or plunger, due to such irnpartly in section therein;
  • a still further object of this invention is to provide inea 'ns for adjusting the position of the fulniina tingcap with relation to the firing pin and to retain the said cap in pr'oper relation to. the firing pin.
  • an ob ect of this nvention is to provide means for ignltmg the explosive charge o'fj-a projectile and for so timing it that the ignition will bedelayed a predetermined time after the said projectile has struck an object, the ,purpo's'e'heing to permit the projectile to penetrate *the object to insure the explosion of the proj'ecti'le on the inside rather than 'on the outside of the mark.

  • Fig. 12 illustrates a sectional view on the Fig. 13 illustrates a sectional viow on tho line 12 12 of Fig. fl-with partsin different ustinents
  • Fig. 14' lllustrates a view inelevationof on the nut is operative to hold parts of the device assembled.
  • the firing pin comprises a head 18 which is struck by the hammer, a stem 19 and a. body 20 from which the pins 21 project, it being understood that thenumber of firing pins may be increased or diminishedaccording to requirements and for the purpose of illustration, three firing pins are here shown.
  • a shoulder 22 forming an abutment for a spring 23 which spring encircles a portion of the body and has a bearing on the shoulder 21 formed in the housing 25 for the firing pin.
  • a plate 25 is secured to one end of the said housing and the sald plate has an aperture 26 in which the head 1s shdablc and in which it is guided, the said plate being secured to the housing by fastenings such as screws 26.
  • the housing is furthermore provided with a radially extending channel 27 in which cups 28 are stationed, the said cups being held in place by a sleeve 29 which encircles a portion of the housing of the firing pin, as fully shown in the drawing.
  • the guards are, however, held near the center of the casing by springs 32 seated in the cups and in the recesses of the guards, but the tension of these springs is readily overcome by the centrifugal force and they,
  • each has an aperture 33 so that air may pass therethrough to prevent cushioning of the said guards, and the faces of the said guards are concaved as shown at 34 to form seats for the shank of the firing pin and to insure clearance of the head of the firing pin.
  • the cap sockets 35 are formed in a plate 36 secured within the casing by the ring nut 15, which ring nut bears against one side near its edgeand holds it in intermediate relation with the housing of the firing pin.
  • the plate has apertures 37 which extend through the said plate and merge with the cap sockets and the inner face of the said plate 36 has an angular seat 38 in which a disk 39 is held, the said disk 39 serving to retain the caps in their sockets.
  • Thedisk is held between the plate 36 and the housing of the firing pin and it may be penetrated firing pin, the plate 36 ha ribs 41 on one of its faces, which lie in slots 0r recesses42 formed in the outer face of the firing pin housing.
  • a modificationof the cap holding plate is shown in Fig. 9, the same comprising a plate 45 having threaded apertures 46 in which apertured plugs 47 are threaded, the apertures being designed for the reception of shanks of the caps 48 and the said apertures form ways through which the flame reaches the charge.
  • the plate 45 is in other respects of the same construction as the plate 36 and further detailed description thereof is believed to be unnecessary.
  • the inner end of the fuse casing is provided with a disk or plate 49 which holds the explosive 50, which is ignited by the caps, it being understood that the charge 50 is utilized for igniting the charge contained in the projectile.
  • the device shown in Fig. 7 is employed, the same comprising a casing 51 threaded as at 52 to enter the projectile and it is the purpose of the inventor that this casing 51 be made of such appropriate length as to increase or diminish the time between the impact of the projectile and the firing of the charge.
  • the casing may, therefore, be made to extend a greater or less distaneeihto the projectile as" the requirements of practice may demand which carries the cap 57 is held in place by a' ring nut- '54 and the charge 5 5 is likewise held in place by a disk '56.
  • the plate 53 may contain any number of caps 57 for it is desired to insure against defects in the operation of one or more. igniting devices. For the purpose of illustrating the invention, however, the showing in Fig. 7 is believed to be sufficient, as one skilled in the art will readily appreciate that these parts may be duplicated.
  • the means for exploding the cartridge preferably comprises the structure heretofore described for exploding the caps of the fuse, particularly shown 1n Figs.
  • the head 63 has a leaf spring 64, which leaf spring lies in a recess 65 of the head and the said spring is anchored or secured to one end of the casing as at 66. The action of this spring is to force the head inwardly when the guards 67 move to release the head.
  • the wall of the casing tapers and the depth of the thread is graduated by being reduced in depth toward the thin end of the casing, this b ing for the purpose of maintaining the strength of the wall of the casing uniform practically throughout its length.
  • the casing 68 and housing 69 are of the construction heretofore described, but in the present embodiment of the invention, the guards 70 are slidable in the channel 71 formed in the housing and a conical spring 72 having a base of a diameter approximately the diameter of the channel is applied to the channel with the base of the spring lying against the sleeve 73.
  • the guards 7 0 have their outer faces provided with concavities 7 the walls of which are tapered approximately to the taper of the s'prii'lgs when compress-led so that the said springs will nest in the cnncavities when the guards move radially.
  • the guards have central apertures" 75 to permit the air to escape therethrough and each concavity furthermore constitutes a seat for the end 76 of the spring so that the spring is held in proper position while the guard with relation to it.
  • the face plate 77 has a slot 78 therein and the head 79 of the firing pin has a 'transve ely disposed guiding pin 80 therein which travf els in the slot of the pin 7 8 and in a slot formed in the housing.
  • the guiding pin 80v is loosely appliedto the head so that it may be inserted or removed.
  • he number of firing pins increases the etiiciency of the fuse and guards against defects of the caps so that if one or more of the caps are not exploded, one or more of the other caps will be effective to fire the charge.
  • caps from different localities may be employed so that if the caps of one locality had been tampered with, those from other localities when employed in the manufacture of the fuse would produce the de sired result.
  • a fuse a casing, a housing therein having transversely disposed ways, guards in the ways, cups with relation to which the guards telescope, springs interposed between the cups and the guards, salt guards having openings therein for the passage .of air, a firing pin slidable in the housing, the said firing pin having a head engaged by the guards to prevent movement of the firing pin, said guards being moved by centrifugal force to release the firing pin, means for imparting initial movement to the firing pin to prevent resetting of the guards, means for holding caps in front of the firing pin, and means for operating the firing pin upon impact of a projectile.
  • a casing a housing therein having transversely disposed ways, guards in the ways, cups with relation to which the guards telescope, springs interposed between the cups and the guards, said guards having openings therein for the passage of air, a firing pin slidable in the housing, the said firing pin having ahead engaged by the guards to prevent movement of the firing pin, said guards being moved by centrifugal force to release the firing pin, means for imparting initial movement to the firing pin to prevent resetting of the guards, a plate having seats for caps, a disk'on the plate for holding the caps in place, means for holding the plate With the caps in position to be exploded by the firing pin, and means for operating the firing pin upon impact of a projectile.
  • a firing pin comprising a head, shank and body, a plate on the h0us ing having an aperture in which the head.
