Abstract

A crossbow may include a stock assembly including a rail with a rail groove, a nock point and a trigger mechanism. A first bracket assembly is pivotally attached to the stock assembly, wherein the first bracket assembly includes a first roller and a first primary cam. A first limb has a rearward end attached to the stock assembly. A first roller engages a forward end of the first limb. A second bracket assembly is pivotally attached to the stock assembly. The second bracket assembly includes a second roller and a second primary cam. The second limb has a rearward end attached to the stock assembly. A second roller engages a forward end of the second limb. The first limb and the second limb extend on opposite lateral sides of the stock assembly. A bowstring extends between the first primary cam and the second primary cam. When the bowstring is pulled along the rail toward the nock point, the bowstring and control cables pull the first primary cam and the second primary cam toward the stock assembly thereby causing the first bracket assembly and the second bracket assembly to pivot toward the stock assembly, wherein during the pivoting the first roller bends the first limb toward the stock assembly to flex and store energy and the second roller bends the second limb toward the stock assembly to flex and store energy.
