Patent Images
1. An assembly comprising:
- a crossbow stock;
a pair of limbs extending from respective sides of said stock;
a bowstring cable extending between said limbs;
a trigger assembly arranged with said stock and operable to hold and release said bowstring cable from a drawn position;
said trigger assembly having;
a cable catch assembly;
a trigger mechanism including a trigger selectively operable in a pull direction to release said cable catch assembly to release the bowstring cable;
a trigger pull weight adjustment mechanism including a pusher member biased by a resilient force against a portion of said trigger mechanism against said pull direction;
an adjustable stop; and
a resilient member arranged in compression between said stop and said pusher member, and wherein the position of said stop is movable to adjust the resilient force applied by said resilient member against said pusher member;
to change the trigger pull weight of said trigger.

14. A trigger assembly mountable with a crossbow stock, comprising:
-
a cable catch assembly; a trigger mechanism including a trigger selectively operable in a pull direction to release said cable catch assembly to release a crossbow bowstring cable; a trigger pull weight adjustment mechanism including a pusher member bracing a portion of said trigger mechanism against said pull direction; a compressible spring which applies a resilient biasing force against said pusher member; and
an adjustable stop, wherein said spring is arranged in compression between said stop and said pusher member, and wherein the position of said stop is movable to adjust the biasing force applied by said spring against said pusher member to change the trigger pull weight of said trigger. - View Dependent Claims (15, 16, 17)
