Definitions

  • the present invention relates to a breechloading bomb thrower which is light and can be divided in two parts adapted each to be carried on mans back, the novel bombthrower exhibiting, besides, the following main characteristic features:
  • Safety devices which permit liring: (1) only after the breech has been completely closed so as to be ready for tiring; (2) only after a member intended to avoid accidental tiring has been revolved in one rather than in another direction.
  • Figure 1 is a view showing the general arrangement of the bomb-thrower.
  • Figure 2 is a longitudinal section through the launching tube with the special bore proile.
  • Figure 3 is a detail section showing how the bomb-thrower is made to rest on its base, and detail of the movement which permits of the lugs being brought into horizontal position even when the base is not horizontal.
  • Figures 4 and 5 show the detail of the movement which permits of the barrel being shifted in order to load the cartridge or launching charge into it from the rear.
  • Figures 6 and .7 diagrammatically show the arrangement Jfor opening and closing the barrel, the closing being rendered semi-automatic.
  • Fig. 8 is a fragmentary view partly in section showing the eccentric mounting for the barrel.
  • the arm comprises the bomb-thrower proper and the base.
  • the bomb-thrower proper comprises: the launching tube or barrel 8; a two-legged ysupport 9, in the bottom portion 10 of Whose solid body Va hole is formed for reception of the spindle 14 connecting it to the frame; an operating fork 11 ( Figures 6 and 7); a carriage divided into two parts viz. the upper part 13 to which the support 9 is connected by the spindle 14 and which is pivotally mounted as will be seen below about a horizontal axis normal to the axis of the lugs igure 3) in order to enable the correction for lateral listing of the arm.
  • Eccentric sleeves 12 are carried by the arms of the fork and are journalled in the legs of the support 9 and receive the terminal of the trunnions l2 of the barrel 8.
  • rEhe bottom part 15 ( Figure 3) is adapted to revolve on the plate 2O and guided by the circular rim 21 as Well as by a spindle 34 normal to the said plate, the part 15 serving for pointing i-n azimuth; La stirrup 16 with pivoting handle 17 which, when in horizontal position serves for pointing in azimuth and when in vertical position serves to correct the listing.
  • two-coaxial screw spindles 18 are provided, which move in the vertical plane passing through -the axis of the launching tube; this device is operated by means of a handwheel and is 'arranged at the front and connected to the support 9 at the top and to the carriage at the ⁇ bottom.
  • the base essentially comprises: a Wood platform 19; a plate 2O and a circular rim 21, these parts being connected to one another by anchor bolts 22.
  • a plate or ploughshare 23 is applied -to the platform at the rear, extending the whole length of the platform, and two further harpoon-shaped plough-shares 24 adapted to slide in vertical direction may be applied to the front portion of the platform.
  • the said harpoons are provided with teeth which permit of the harpoons being iixed in any desired position; the ends of the bolts 22 are projecting below and tooth-shaped so that they may be considered as further harpoons.
  • Two metal arms 25, connected ⁇ to the platform sides by means of ball-joints can be opened out and loaded with earth-filled bags or other weights; they also serve to facilitate the shifting of the bomb-thrower.
  • v26 is fthe chamber for reception of the launching charge; 27 is a. connecting portion in the form of a truncated cone between the. said chamber ⁇ and the reduced portion 28; 29 is a gas eX- fpansion chamber; 30 isa further gas eXpansion chamber in which the projectile tail may find accommodation if projectiles iitted with tails are used; 31 is the lodging for the bomb; 32 is a. cardboard disc; 33 is lthe launching' charge, this charge and the said disc being contained in a case the bottom (inclusive of itsedge) of which is .lodged in a recess formed in the thickness of the breech.
  • the gases behave as tollowstIn the chamber 26.
  • the gases in which the deiiagration oi' the launching charge occurs, the gases, before the deagration is completed, owing to their extreme elasticity, tend to move toward the forward portion of the barrel and act upon the bomb; their expanding action, however, is hemmed by the narrow passage 28 due to which the pressure in the chamber 26 is increased andthe launching charge is completely burnt; this eflect is assisted, though in a very scanty proportion, by the cardboard disc 32 which, in spite of its diameter being larger than that of the reduced section, is obliged to pass through the latter.
  • the now completely disengaged gases go past the reduced section 28 into the bomb lodging 31.
  • the gases acquire a high velocity whereas their pressure sinks and such a fact would be detrimental inasmuch as the gases would iinpinge the bomb prematurely and act thereon through their velocity alone.
  • the two expansion chambers 29 and 30 have been provided, in which a portion of the gas velocity is again converted into pressure so that the gases can exert their action more rationally on a larger surface of the bomb.
  • the bomb may be fitted with a tail, this tail being accommodated in the expansion chasm ber 30.
  • the tail may be hollow, with open bottom end.
  • a recess is formed for reception of a spindle 34 secured to the bottom portion of the frame.
  • retiros/'i spindle 34 serves as a guide for the bornbl thrower when the latter is revolved in an horizontal plane for pointing in azimuth;
  • the spindle also facilitates the operation of concave surface of the bottom portion 15. Y Vith this arrangement, which permits themupper portion 13 to revolve about the spindle 35 (set at right angles to th-e axis or" the lugs) the barrel 0In the bomb-thrower may be given a lateral inclination to the rightor to the left in order to bring the lugs in horizontal position when required, thus correcting the lateral listing.
  • ligure l shows the position occupied by the throwing tube 8 when ready for firing, that is to say when the back end of the breech bears against the support 9 and in conjunction therewith forms a tight closure.
  • a tooth 3G projecting from the breech and solid therewith serves to lock the launching tube to the support in i'iring position.
  • Figures 4 and 5 show that the two sides or Shanks of the support 9 project above the support body and aii'ord bearings for the eccentric sleeves 12 ot the operating fork 11. Due to the eccentricity of the sleeve 12, when the breech is being opened, Jfor instance, the sleeves 12 revolve about anaxis arranged eccentrically relatively to the trunnions 12 so that the barrel is raised ( Figure 5) the locking tooth 36 released and the throwing tube allowed to pivot in order to be opened. After this pivoting movement, the throwing tube occupies the position indicated in dotted lines in Figure 5; now the case containing the launching charge can be introduced into the tube till the edge of said case rests in the seat formed in the breech thickness for this purpose.
  • the operating Jfork. 11 is provided with a handle 37 having an inward extension, providing a tooth 38 which serves to lock the fork in the position it occupies when the breech is closed.
  • a pin 39 is provided on the tooth 38, the pin being arranged to slide in a groove 40 formed in a member carried by one of the stationary shanks 9 for the support of the launching tube 8.
  • a portion of the groove length is an arc the center of which coincides with the center of the pieces l2, and the following length extends the direction of the tangent of the said arc.
  • a device of the class described comprising a supporting base, a support adjustably connected therewith and constituting' a breech block, a launching barrel carried by the support and cooperative with the breech block7 said support having spaced side mem-- bers, lugs carried by the .side members, a fork having its arms connected with the lugs and operable to move the barrel toward or away from the breech block, a tooth carried by the barrel adapted to engage in a recess in the breech block when the barrel is in its launching position.
  • a device of the class described comprising a supporting base, a support adjustably connected therewith7 a launching barrel connected with the support, said support constituting a breech block for the barrel, a fork member having eccentric sleeves associated with its arms for raising or lowering the barrel with respect to the breech block, and a tooth carried by the fork member adapted to engage a tooth carried by the barrel as and for the purpose .set forth.
  • a device of the class described comprising a supporting base, a support adjustably connected therewith and including spaced sides, a launching barrel associated with the support, said support constituting' a breech block for the barrel., a fork member having its arms eccentrically connected with the sides of the support and operable to raise and lower the barrel with respect to the breech block, one side of the support having a ⁇ grooved member' thereon, a tooth carried by the fork member and engageable in the groove of the member and' adapted to coact with a tooth carried by the barrel for locking the launching barrel with the breech block.
  • a device of the class described comprising a supporting base, a launching barrel mounted thereon for universal movement, said base having a ground engaging plow the purpose set forth.
