Abstract

Abstract A crossbow structure for projecting an elongate feathered arrow having a butt portion and an elongate barrel with a bow secured to a forward or muzzle end of the elongate barrel. The barrel has a bore having longitudinally spaced resiliently supported arrow positioning members therein and longitudinal slots at each side of the bore for travel of a bow string therealong. The crossbow structure has a trigger member and linkage operatively connected to a sear for selectively holding and releasing the bow string. A cam safety is positioned to be selectively moved into and out of engagement with the trigger member and an elongate safety pin is positioned to be selectively moved into and out of engagement with the sear for holding or releasing the bow string. The stock has an aperture therein for access to a gripping portion adjacent the trigger member. An upwardly biased arrow positioning member is positioned at both the breech and the muzzle ends of the barrel.

Claim 3
Dependent Claim 95 words
The crossbow structure as set forth in claim 1 wherein said sear means includes: a. a sear guideway extending in a line transversely of the breech portion of the longitudinal slots and adjacent a rear end of the bore; b. an elongate rod having a bevelled upper end movable within said sear guideway; c. a flange adjacent a lower end of said sear rod, said flange being engaged by said trigger means for moving said rod; and d. resilient means within said stock engaging said flange for urging said sear rod into a nonfiring position.
Claim 4
Dependent Claim 85 words
The crossbow structure as set forth in claim 2 including: a. an elongate safety pin engageable with said sear flange for holding said sear rod in the nonfiring position; b. a notch in said safety pin sized to permit said sear flange to move therethrough; and c. keeper means engageable with said safety pin for selectively holding same in engagement with said sear flange and for holding said safety pin in position having said notch therein positioned to permit said sear flange to move therethrough.
Claim 5
Dependent Claim 48 words
The crossbow structure as set forth in claim 3 wherein: a. said safety pin has a pair of longitudinally spaced recesses therein to receive said keeper means; and b. said keeper means is a resilient member sized to be selectively received within said recesses in said safety pin.
Claim 6
Dependent Claim 93 words
The crossbow structure as set forth in claim 2 wherein said trigger means includes: a. a trigger guideway within said stock communicating with said sear guideway; b. a trigger member pivotally mounted within said trigger guideway, said trigger member having a lug portion extending therefrom; and c. an elongate lever within said trigger guideway, said lever being pivotally mounted intermediate its ends and having one end engaging said lug portion of said trigger member and the other end engaging said sear flange for moving said sear out of engagement with said bow string.
Claim 7
Dependent Claim 49 words
The crossbow structure as set forth in claim 5 including: a. a notch in an edge of said trigger member; and b. a rotatably mounted cam safety positioned to be selectively moved into said notch whereby said cam safety engages and positions said trigger member in a nonfiring position.
Claim 8
Dependent Claim 89 words
The crossbow structure as set forth in claim 6 including: a. resilient means engaging said trigger member and said trigger guideway for positioning said notch in said trigger member to receive said cam safety; b. friction means associated with said cam safety for retaining same in an adjusted position; and c. a recess in one side of said stock for said cam safety, said recess being sized to permit said cam safety to move between a safe position in said notch and a firing position out of said notch.
Claim 9
Dependent Claim 68 words
The crossbow structuRe as set forth in claim 7 wherein: a. said trigger member is a planar member having a forward edge and a rear edge; b. said notch is in said forward edge of said trigger member; c. said lug portion of said trigger member extends rearwardly from said rear edge of said trigger member; and d. said sear rod is positioned rearwardly of said trigger member.
Claim 10
