Abstract
An arrow gun is provided having a controllable retention force on the arrow. By setting the retention force on the arrow, increased energy from motive compressed gas can be imparted to the arrow. The arrow gun also includes a damping coupling for reducing vibration of an unsupported length of the barrel.
Claims16
A method of releasably engaging a hollow portion of an arrow with a barrel of a gun, the barrel extending along a longitudinal axis and having an outer diameter sized to be slideably received with the hollow portion of the arrow, the method comprising:
- (a) disposing a length of the barrel within the hollow portion of the arrow and engaging a gripping surface of the gun with an outside surface of the arrow, wherein a damping coupling is located between an outside surface of the barrel and the gun, the damping coupling longitudinally intermediate the gripping surface and a fixed connection of the barrel and the gun.
A method of securing a barrel to a gun, the barrel extending along a longitudinal axis and having an outer diameter sized to be slideably received within a hollow portion of an arrow, the method comprising:
- (a) making a connection between a first end of the barrel and the gun, wherein a second end of the barrel defines a free end of the barrel;
- (b) locating a damping coupling between the gun and an outer surface of the barrel, the damping coupling being longitudinally intermediate the connection and the free end of the barrel, and
- (c) providing a gripping surface to contact an outside surface of the arrow with one of at least one of a first retention force and a different second retention force.
A method of engaging an arrow having a hollow portion with a barrel of a gun, the barrel extending along a longitudinal axis and having an outer diameter sized to be slideably received within the hollow portion, the method comprising:
- (a) disposing the hollow portion of the arrow onto the barrel of the gun;
- and
- (b) restricting a motion of the barrel relative to the gun with a damping coupling between an outside surface of the barrel and the gun, the damping coupling located between a first end of the barrel connected to the gun and a second end of the barrel defining a free end of the barrel.
