Definitions

  • the present invention relates to a fuse for grenades and the like, particularly for hand grenades.
  • a further object of the invention is to provide a fuse :for hand grenades and the like wherein the safety strip is interposed between the firing pin and the primer and when the safety strip is removed from the grenade the firing device is moved from an inclined position to a position in alignment with the primer while at the same time tensioning the spring.
  • a still further object of the invention is to provide a fuse wherein the firing device comprises a group of three levers movable angularly with respect to certain .pivots and arranged inoperative abutment relation to each other so as to reduce the stress exerted by the spring under the tension of the firing pin upon an external lever of such group.
  • the external lever begins its angular movement when the grenade is thrown after removal of the safety strip.
  • a further object is to provide a fuse for grenades wherein the metallic members forming the firing device fall off during the flight 'of the grenade after the firing pin has struck the primer.
  • Figure 1 is an axial cross-sectional view of a grenade "in safety position
  • Figure 2 is a similar view showing the grenade in firing position
  • Figure -3 is an axial cross-sectional view of a modified forr'n 'of t he invention.
  • Figure '4 is a plan view "(if the safety stri Referring to Figures -1 and 2 of the drawing, '17 llfdieates'th'e substantially cylindrical body or a grenade which com rises a lower portion containing the bursting charg'e atent 2,737,116 "Patented Mar. 6, 1956 and an upper portion wherein the firing device is positioned. Between the lower and upper portion of the body there is interposed a first safety member in the form of a strip 3 which covers substantially the primer 4 arranged on the detonator contained in the bursting charge.
  • the firing device comprises a shank 20 having a head 1 provided with a recess wherein an element 19 of the lever 8 penetrates.
  • the element 19 acts as -a pivot about which the shank 20 and the firing device oscillate.
  • a spiral spring 2 is mounted which is contained in a cup 22 provided with a firing pin 23.
  • a sleeve 21 which abuts against the head 1 of the shank 20. The spring is located between the bottom of the cup 22 and the sleeve 21'.
  • the shank 20 and the members associated therewith are contained in a holder 24 which is provided at the bottom with a hole for the passage of the firing pin 23.
  • the holder 24 is provided with a projection 25 which engages an opening 31 made in the strip 3.
  • a second safety device in the form of a hook 5 is pivoted at 27.
  • the hook 5 comprises a lug 2S and an arm 29.
  • the lug 28 passes through a slot made in the holder 24 and engages the lower surface of the cup 22 while an arm 29 penetrates an opening provided in the intermediate lever 7.
  • v I In the position shown in Figure l the firing device is inclined with respect to the axis of the primer and the arm 29 abuts against the lever 7 thereby preventing the latter from looking. In this position the spring 2 is unloaded.
  • the holder 24 abuts at its lower part against a slotted wall located in the upper portion 13 of the body and flush with the strip 3 which may slide in such slotted wall.
  • lever 6 jour-nalled at 9 on the upper portion 18 'of the body is located externally of the grenade body.
  • the lever 6 has an arm adjacent the body and has a slot wherein the end 32 of the strip 3 penetrates.
  • the end '32 is built to engage the lever 6 in order to prevent the latter from looking.
  • the end of lever 8 abuts against the lever 7 near the pivot point 3t thereof and the lever 7 abuts against the lever '6 near the pivot point :9. It is apparent that the relative location of the abutment points of the levers with respect to their pivot points causes a reduction in the stresses so that only a fraction of the force applied to the inner lever '8 acts on the external lever 6.
  • a device indicated at 12 which prevents the members forming the firing device and the lever from falling off during the flight of the grenade and are therefore intended to form fragments.
  • the bursting charge is contained in a metal tube provided with two end elements 34 and between the tube and the wall of the grenade there is a metal cylinder 11 provided in the form of a spiral which is intended to be broken into fragments upon bursting of the charge.
  • the grenade may be thrown by a rifle by the usual devices used therefor.
  • the grip member 13 is made with suflicient weight so as to cause the automatic removal of the strip 3 from the grenade upon the throwing thereof by means of a rifle.
  • the detonator is introduced into the bursting charge and comprises and plurality of igneous elements 14, 15 and 16 designed to delay the transmission of fire from the primer to the exploding charge. These elements are contained in a tight metal casing which permits better preservation of the grenade.
