Adjustable silencer booster with spoked piston engagement shoulder
View Patent ↗The herein proposed device relieves an autoloading handguns' barrel from the weight of the silencer allowing it to cycle properly. This improved booster housing for a silencer affords the user ten positions of orientation. A more robust orientation mechanism which minimizes rotational movement of the associated piston when it is fully seated within the booster housing is provided for. Increased accuracy of the host firearm is achieved through the minimization of rotational play. My improved booster housing design is lighter in weight than other similar designs and utilizes a coaxial expansion chamber between the housing and the interior of the silencer tube to increase sound reduction.
1. A booster for a silencer, comprising:
a piston with a proximal end and a distal end, the proximal end of the piston configured to couple to a firearm such that a projectile can pass thorough the piston from the proximal end to the distal end, the distal end of the piston comprising a flange with a plurality of spokes; and
a housing configured to couple to a silencer, the housing comprising an internal shoulder with a plurality of notches to receive a plurality of spokes of the piston flange;
wherein the piston is translatable relative to the housing in at least one of the proximal and distal directions during discharge of a firearm coupled to the piston, and
wherein a peripheral surface of the piston flange contacts an inner surface of the housing and slides along the inner surface during translation of the piston relative to the housing,
wherein the housing is positioned within a firearm silencer and further comprises a plurality of holes such that expanding gases produced from a discharged firearm coupled to the booster can escape the housing in a direction substantially transverse to the path of a discharge projectile.
2. The booster of claim 1 , wherein the booster is configured such that when the notches of the internal shoulder receive the spokes of the piston flange, the internal shoulder prevents the housing from rotating relative to the piston.
3. The booster of claim 2 , wherein the booster is further configured such that when the internal shoulder prevents rotation of the housing relative to the piston and when the booster is coupled to a silencer and a firearm, the silencer is prevented from rotating relative to the firearm.
4. The booster of claim 1 , wherein the piston flange has ten spokes and the internal shoulder has ten notches.
5. The booster of claim 1 , the booster further comprising a rear cap configured to couple to the housing, the rear cap comprising two features outwardly protruding from the distal face of the rear cap, the two features at opposite transverse locations on the rear cap to facilitate for removal of the rear cap.
6. The booster of claim 5 , the booster further comprising an o-ring located interior to the rear cap, the o-ring positioned to contact the piston.
