A barrel clamp for a Gatling-style firearm, or “mini-gun,” provides vanes for the direction of fresh air currents into the muzzle area of the firearm. The directed air streams contribute to cooling the barrels while in the firing cycle and also towards the disruption of fuel-rich gasses which contribute to muzzle flash.
1. A barrel clamp comprising:
a. a base plate;
b. a central support structure defining an axis; and
c. a muzzle housing positioned on an extreme end of the support structure opposite the base plate, said muzzle housing further comprising a wall with a plurality of vanes, each with at least one associated vent, each said vent positioned to direct airflow into a central chamber of the muzzle housing when the barrel clamp is rotated about the axis,
wherein the base plate and said muzzle housing each have a plurality of orifices such that there is an equal number of said orifices on the base plate and on the muzzle housing, each said orifice on the muzzle housing being paired to an opposed said orifice on the base plate so that barrels may be inserted therethrough, with each said orifice on said muzzle housing opening inside the central chamber.
2. The barrel clamp of claim 1 , the plurality of said vanes equaling the plurality of said orifices in the muzzle housing.
3. The barrel clamp of claim 2 , each said vane and each said vent being positioned in a manner to direct airflow over one of the orifices in the muzzle housing.
4. The barrel clamp of claim 1 , each said vane and each said vent being positioned in a manner to direct airflow over one of the orifices in the muzzle housing.
5. The barrel clamp of claim 1 , the support structure being a tube with an opening in the central chamber of the muzzle housing, said opening serving as a vent.
6. The barrel clamp of claim 5 , the plurality of said vanes equaling the plurality of said orifices in the muzzle housing.
7. The barrel clamp of claim 6 , each said vane and each said vent being positioned in a manner to direct airflow over one of the orifices in the muzzle housing.
8. The barrel clamp of claim 5 , each said vane and each said vent being positioned in a manner to direct airflow over one of the orifices in the muzzle housing.
9. A barrel clamp comprising:
a. a base plate;
b. a central tube support structure having a length greater than its diameter, said length defining an axis; and
c. a muzzle housing, said muzzle housing further comprising a plurality of vanes, each associated with one of a plurality of wall vents positioned to direct airflow into a central chamber of the muzzle housing when the barrel clamp is rotated about the axis,
d. the central support tube having an opening within the central chamber of the muzzle housing serving as a central vent;
wherein the base plate and said muzzle housing each have a plurality of orifices such that there is an equal number of said orifices on the base plate and on the muzzle housing, each said orifice on the muzzle housing being paired to an opposed said orifice on the base plate so barrels may be inserted therethrough, with each said orifice on said muzzle housing opening inside the central chamber.
10. The barrel clamp of claim 9 , the plurality of said vanes equaling the plurality of said orifices in the muzzle housing.
11. The barrel clamp of claim 10 , each said vane and each said wall vent being positioned in a manner to direct airflow over one of the orifices in the muzzle housing.
12. The barrel clamp of claim 9 , each said vane and each said wall vent being positioned in a manner to direct airflow over one of the orifices in the muzzle housing.
