Abstract
A spring loaded capsule that accepts a rotatable shaft upon which a launcher arm or other type of arrow support mechanism is mounted. The capsule includes a spring for exerting a biasing force against the rotatable shaft and includes a mechanism for limiting the rotation of the shaft in response to the spring bias. The capsule may be used interchangeably with a variety of similarly sized shafts and a variety of launcher arms.
Claims18
A capsule adapted for use with an archery arrow rest including a rotatable shaft and an arrow support arm connected to the shaft, said capsule comprising:
- (a) a barrel possessing a substantially hollow interior and possessing two substantially open, opposed ends in communication with the hollow interior;
- (b) a tension spring housed substantially within the hollow interior of said barrel;
- (c) a first end cap disposed at a first open end of said barrel, rotatable with respect to said barrel, and operatively connected to said spring such that any tension on said spring acts upon said first end cap to rotationally bias said first end cap relative to said barrel;
- (d) means for securing the shaft to said first end cap such that said end cap rotates concurrently with the shaft relative to said barrel;
- (e) means for limiting the rotational range of said first end cap and the shaft relative to said barrel;
- (f) a second end cap disposed at the second opposed end of said barrel and operatively connected to said spring such that selected positioning of said second end cap relative to said barrel causes the tension on said spring to selectively vary.

An arrow support device adapted for use with an archery bow and adapted for use with an arrow support arm connected to a rotatable shaft, said arrow support device including:
- (a) a tubular barrel possessing a substantially cylindrical outer periphery and a substantially cylindrical inner periphery, possessing a substantially longitudinal axis, and possessing a slot extending substantially arcuately therethrough substantially near one longitudinal end thereof and possessing a threaded hole substantially radially extending therethrough substantially near the other longitudinal end thereof;
- (b) a substantially helically configured, coiled torsion spring housed substantially within the interior of said barrel and possessing a substantially longitudinal axis, with the longitudinal axis of said barrel being substantially coextensive with the longitudinal axis of said spring when said spring is housed substantially within the interior of said barrel, each end of said spring configured in a substantially longitudinally extending finger;
- (c) a pin;
- (d) a pair of set screws;
- (e) a first end cap including a substantially cylindrical first head portion possessing a substantially longitudinal axis and a substantially cylindrical first nipple portion possessing a substantially longitudinal axis and including a substantially cylindrical first borehole substantially concentrically extending therethrough possessing a substantially longitudinal axis and adapted to receive the shaft, the diameter of said first nipple portion being smaller than the diameter of said first head portion such that a first lip is formed in said first end cap, the substantially longitudinal axes of said first head portion, said first nipple portion, and said first borehole being substantially aligned, the distal end of said first head portion possessing a first threaded hole substantially radially extending therethrough and adapted to receive one of said set screws such that said set screw maybe rotated within said first threaded hole to press forcefully against the shaft when said shaft is received in said first borehole of said first end cap, said first nipple portion possessing a hole substantially longitudinally extending therein adapted to receive one finger of said spring, said first nipple portion also possessing a hole substantially radially therein adapted to receive a first longitudinal end of said pin, said first lip of said first end cap adapted to seat against one longitudinal end of said barrel such that said first nipple portion extends into the hollow interior of said barrel and whereby said pin may extend into the substantially radially extending hole of said first nipple portion and simultaneously extend into the slot in said barrel;
- and
- (f) a second end cap including a substantially cylindrical second head portion possessing a substantially longitudinal axis and a substantially cylindrical second nipple portion possessing a substantially longitudinal axis, the diameter of said first nipple portion being smaller than the diameter of said first head portion, such that a second lip is formed on said second end cap, the substantially longitudinal axes of said second head portion and said second nipple portion being substantially aligned, the distal end of said second nipple portion possessing a hole longitudinally extending therein adapted to receive the other finger of said spring, said second lip of said second end cap adapted to seat against the other longitudinal end of said barrel such that said second nipple portion extends into the hollow interior of said barrel and whereby the other of said set screws may extend through said threaded hole in said barrel to press forcefully against said second nipple portion.
