An accelerating
assembly effectively to increase the cyclic rate at which the trigger of a semi-
automatic firearm can be actuated to
discharge the weapon. The firearm has a supporting device, a
receiver housing supported from the supporting device, a trigger and trigger mechanism secured to the
receiver housing. The accelerating mechanism incorporates structure that permits the
receiver and the trigger to translate rearwardly a predetermined distance with respect to the supporting device in response to the
recoil imparted by the
discharge of the semi-
automatic firearm. A biasing arrangement continuously urges the receiver, and trigger, to translate forwardly with respect to the supporting device substantially that same predetermined distance. A locating stop is mounted on the supporting device. The locating stop is disposed to be engaged by the shooter's finger after the trigger has been actuated to fire the semi-automatic weapon. That engagement of the shooter's
trigger finger with the locating stop effectively immobilizing the shooter's
trigger finger with respect to the supporting device until the shooter releases the trigger. The method of the present invention operates by depressing the trigger with a shooter's
trigger finger in order to
discharge the firearm. The shooter's finger is then immobilized in the position it has assumed to discharge the firearm. The trigger is translated away from the immobilized trigger finger to effect a total disengagement therebetween. Sequentially thereafter the trigger is biased into engagement with the immobilized trigger finger to effect successive discharges of the firearm.
