Definitions

  • the present invention is a new and useful improvement in the means of holding);
  • breech block firmly in position while the shot is tired, by means of independent lockino' members which transmit the pressure fired, directly to the frame or the gun instead of to the crank i'nechauism which reci 'n-ocates the breech block.
  • Fine. 1. and 2 respectively show a vertical and. horizontal section of the gun mechanism.
  • 3 is a cross section on the line A.B Fiji. 1.
  • the operatingcrank A carries. in addition. to the journal by which. the breech block is reciprocated. through the medium of a connecting rod. a projection on each side in which a cam faced groove B is cut.
  • This groove ei'igages the rear ends of the locking' levers which are pivoted at F on the frame of the ⁇ 11111.
  • levers (I by means of the grooves B to pivot by means of the shape of the grooves B into such a. position that the shoulders formed on the forward ends of the locking levers C engage with the breech block D and'hold it firmly in position while the shot is fired.
  • the arrangement is such that the locking levers are subjected only Specification of Letters Patent.
  • arotating crank having cam faced. grooves. locking levers, subject to com ANTHONY HERMAN GERARD FOKKER.
