Definitions

  • Fig. 1' 1 s a longitudinal view partly n cross-section showing the portions of the machine gun mechanism relatingto the fuse setting.
  • Fig. 2 is an end view of the oscillating head mechanism.
  • a tubular clutch element 10 of the cone-faced type is mounted so that it can slide longitudinally but not turn in the bracket 11, which is integral with the gun case or other suitable fixed part of the gun mechanism.
  • the clutch element 10 is arranged so that when moved to the right as shown in Fig. 1 it can grasp the body of the shell or cartridge 12 and hold it from rotation.
  • a clutch element 13 adapted to grasp the fuse ring 14 of the shell 12 when forced into enga ement therewith.
  • This clutch element 1 is and easily as he could the direca ing in the form of a long sleeve having flanges" 15 and 16 thereon, and terminating at the other end in a collar 17 having a notch 19 therein similar to a jaw clutch, this collar 17 also having an external lug 20, which is arranged so that it can strike against an adjustable stop 21.
  • a shaft 22 extends longitudinally through the clutch element or sleeve 13, and is keyed thereto by means of a feather key connection so that the sleeve 13' can slide longitudinally relative to the shaft 22, while the rotary motion of the shaft 22 is positively transmitted to the sleeve 13.
  • A'spring 23 is locatedbetween the clutch 10 and the flange 15, and another whichis shown projecting into the notch 19.
  • This external sleeve or tube 26 is arranged to slide freely on thesleeve 13, and the sleeve 13 can also turn freely within the external sleeve 26, which is held from rotation by a stud (not shown) connecting it to the reciprocating arm 30, and also by a ridge or key 31 which lies in a suitable notch in the fork of the arm 30.
  • the rounded heads of the fork of the reciprocating arm 30 lie between the flanges 25 and 27, so that the external sleeve 26 is reciprocated by the motion ofthe arm 30.
  • the arm 30 is pivoted at 32 to a fixed portion of the gun or frame, and is oscillated by the action of a reciprocating head 33 which is slidably mounted on the reci rocatrod 34.
  • the reciprocating head 33 is driven by the rod 34 through the action of two intermediate springs 35 and 36, which bear against the head 33 and against fixed collars 37 and 38 which are securedto the rod 34.
  • These springs 35 and 36 may be omitted but are desirable to give a cushioning in the driving force, so asto prevent m due shock and strain.
  • a similar pair of springs 39 and 40 engage fixed collars 41 and 42 secured to the reciprocating rod 34 trans- 'mit the driving force to movable collars 43 so that it can oscillate through a moderateangle.
  • the other arm 45 of the be'll'crank 45 carries a air of studs or'pins47 and 47', be-
  • the torque of the shaft 22 is transmitted by a feather key to the sleeve 13 and collar 17 as has been described,the rotation of the collar 1? being limited by the lug 2O striking the adjustable'stop 21.
  • This stop 21 is attached to a worm gear 54 as shown in cross-section in Fig. 1 and can be rotated to any desired position by the worm 55 operated by the control wheel 56 through suitable gearing.
  • the control wheel 56 also operates at the same time, through the gearing 57, an adjustable stop screw 58.
  • a second adjustable stop 59 is arranged so that it can be independently adjusted by the handwheel 60..
  • An extension 61 on the bell 'crank 45 is arranged to play between the stop 58 and stop 59, and serves to absorbsome of the momentum of the apparatus when in action, though this feature is not strictly necessary and-may be omitted in some constructions if desired.
  • the apparatus may be arranged to operate with either a gas operated or recoil operated type of machine gun, as all that is necessary is to link it to the operating mechanism so a reciprocating motion is applied to the rod 34, as by an oscillating linkage 62 driven by a reciprocating element of the machine gun 63 for example.
  • the linkage 62 is preferably connected so that the rod 34 will be moved to the left on the recoil of the gun, and moved to the right on the counter-recoil; the connection may be modified of course according to the type of gun used, and it is not strictly necessary that the fuse 1setting action occurs on the counterreco1
  • the operation of the mechanism is as operations. First, the clutch 10 meets the body of the shell or cartridge 12 and grips it as shown in Fig. 1, thus holding it from rotation.
  • mosses the mechanism performs the operations of se1zing the shell and setting its'fuse by a notion in one direction, and on the return notion releases the shell and prepares for ;he next cycle by returning to its initial;
  • a drive shaft for rotatin said element, gear-' ing for rotating said s aft, and a spring arranged to store the power required to turn said shaft.
