Abstract:
A breech device for assisting in drawing and releasing an archery bow string, said device comprising a body member having a forward end, a rearward end, an upper portion, a lower portion, and a vertically oriented longitudinally extending structural plane, said forward end comprising support wall means on each side of said plane and forming a generally vertically oriented gap means opening generally longitudinally outwardly at said forward end, trigger means positioned in said gap means and extending generally vertically along a trigger axis from said lower portion thru said upper portion and extending upwardly therebeyond, first pivot means on said trigger means and said lower portion for allowing pivoting of said trigger means back and forth generally in said plane, first and second stop means on said device for limiting the extent of pivoting of said trigger means in either the forward or rearward direction respectively, latch arrest shoulder means on said trigger means positioned above said first pivot means and within said gap means, said shoulder means having at least a first quadrant arc segment arced upwardly, latch arm means positioned in said gap means and having a forward end section and a rearward end section and having a latch point at said rearward end section, second pivot means on said forward end of said latch arm means and said forward end of said body member for allowing downward pivoting of said latch arm means within said gap means for engaging said latch point with said arrest shoulder means within said arc segment to thereby cock said trigger means and prevent pivoting rearward movement of said trigger means in its firing direction until said trigger means is manually, forcibly, rearwardly pivoted from its cocked position toward its firing position, said latch point and said second pivot means lying in a pivot radius line, a bowstring keeper means extending downwardly on said forward end section of said latch arm means and adapted to lie on said arrest shoulder means side of said pivot radius line in the cocked trigger position whereby tension applied to said keeper means by drawing of said bowstring will tend to pivot said latch arm means in a direction tending to forcibly maintain engagement of said latch point with said arrest shoulder means and thereby maintain said cocked trigger position until the trigger is pulled to fire.
