  • the rate of fire of the gun will therefore depend upon the position of the knurled disc 0" upon the regulator arm 0 If it is desired still further to reduce the rate of firing, there may be arranged upon the gun, one after another, a series of two or more spindles 0, each of which comprises an arm 0 With a regulator disc 0 and each of which spindles is situated in such a way that the lever n after .having slipped past the first spindle 0 comes into engagement with the next, and so on. The mean linear speed of the breech bolt may thus be re-' Jerusalem to an extremely low figure.
  • the lever n instead of being mounted on the breech bolt m, may evidently be carried by any other working part having a rectilinear or curvilinear stroke during the operation of the gun.
  • This movable supporting member may be constituted either by the breech slide or the like of a. gas-operated automatic fire-arm for example or by 1 the barrel or by any part moving with the barrel in guns operated by recoil.
