Abstract
Abstract An elongated casing is connected at one end with a bow string trigger released mechanism and gunstock. A pair of bow string interconnected wings are pivotally connected to the other end portion of the casing with the wings and being normally biased forwardly in aligned opposition transversely of the casing by a spring within the casing bearing against one end of push rods pivotally engaging, at their other ends, the respective wing intermediate its ends. Adjustable sight means is secured to the casing between the pair of wings.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
196 words
A crossbow, comprising: a casing having a forward end and a rearward end and having opposing longitudinal slots in its wall intermediate its ends; wing mounting bracket means transversely connected to the forward end portion of said casing for pivoting mounting a pair of wings; a pair of wings respectively connected, at one end portion, to respective end portions of said bracket means for pivoting movement of their other end portions toward and away from said casing; a bow string extending between and connected with said other end portions of said wings; an elongated compression spring within said casing; push rod means passing through said slots and interposed between said wings and said spring for transfering a biasing force exerted by said compression spring, when the latter is compressed, to said other end portion of said wings in a forward direction to pivot the wings forwardly and cause the bow string to exert a force on a projectile and project a projectile forwardly; a plate member connected with the rearward end of said casing; and, trigger means supported by the forward end portion of said stock for releasably holding said bow string in crossbow cocked position.
Claim 2
Dependent Claim
196 words
A crossbow, comprising: a casing having a forward end and a rearward end and having opposing longitudinal slots in its wall intermediate its ends; wing mounting bracket means transversely connected to the forward end portion of said casing for pivoting mounting a pair of wings; a pair of wings respectively connected, at one end portion, to respective end portions of said bracket means for pivoting movement of their other end portions toward and away from said casing; a bow string extending between and connected with said other end portions of said wings; an elongated compression spring within said casing; push rod means passing through said slots and interposed between said wings and said spring for transfering a biasing force exerted by said compression spring, when the latter is compressed, to said other end portion of said wings in a forward direction to pivot the wings forwardly and cause the bow string to exert a force on a projectile and project a projectile forwardly; a plate member connected with the rearward end of said casing; and, trigger means supported by the forward end portion of said stock for releasably holding said bow string in crossbow cocked position.
Claim 3
Dependent Claim
104 words
The crossbow according to claim 1 in which said trigger means includes: a pair of disk latch members respectively flatly connected to opposing side surfaces of said stock in coaxial alignment, each said latch member having a bow string receiving recess in its peripheral surface, said stock having a recess communicating with said pair of latch members; a pair of side plates respectively flatly overlying opposing side surfaces of said stock; a catch pivotally mounted within the stock recess between said side plates and releasably engaging said pair of latch members; and, a trigger slidable within the stock recess and releasably supporting said catch.
Claim 4
Dependent Claim
70 words
The crossbow according to claim 2 in which said push rod means includes: a rod coaxially supported by said casing; a follower longitudinally slidably supported by said rod within said casing, said follower having opposite push rod receiving recesses; and, a pair of push rods respectively nested at one end portion by the respective follower recess and pivotally contacting at their other ends the respective said wing intermediate its ends.
Claim 5
Dependent Claim
55 words
The crossbow according to claim 3 and further including: sight means mounted on said bracket means, said sight means comprising a front sight mounted on the uppermost surface of said bracket means, a U-shaped receiving sight mounted on said bracket means for vertical pivoting movement, and, receiving sight adjusting means mounted on said bracket means.
