Crossbow with pivoting brackets

An archery bow comprising:

• a stock assembly including a rail with a rail groove, a nock point and a trigger mechanism;
• a first bracket assembly pivotally attached to the stock assembly, wherein the first bracket assembly includes a first primary cam;
• a first limb, wherein the first limb has a rearward end attached to the stock assembly, and wherein the first limb has a forward end, wherein the first bracket assembly engages the forward end of the first limb;
• a second bracket assembly pivotally attached to the stock assembly, wherein the second bracket assembly includes a second primary cam;
• a second limb, wherein the second limb has a rearward end attached to the stock assembly, and wherein the second limb has a forward end, wherein the second bracket assembly engages the forward end of the first limb;
• wherein the first limb and the second limb extend on opposite lateral sides of the stock assembly;
• a bowstring extending between the first primary cam and the second primary cam;
• and
• wherein when the bowstring is pulled along the rail toward the nock point, the bowstring operably causes the first bracket assembly and the second bracket assembly to pivot toward the stock assembly, wherein during the pivoting the first limb bends toward the stock assembly and the second limb bends toward the stock assembly.

A method comprising:

• pulling a bowstring rearwardly along a rail of a crossbow stock assembly toward a nock point;
• pivoting a first bracket assembly mounted to the stock assembly toward the stock assembly and pivoting a second bracket assembly mounted to the stock assembly toward the stock assembly;
• wherein pivoting the first bracket assembly rolls a first roller along a surface of a first limb thereby bending the first limb toward the stock assembly;
• wherein pivoting the second bracket assembly rolls a second roller along a surface of a second limb thereby bending the second limb toward the stock assembly;
• holding the bowstring at a nock point;
• and
• pulling a trigger of a trigger mechanism of the crossbow and releasing the bowstring from the nock point of the crossbow, wherein energy stored in the first limb and the second limb is released and the first limb and the second limb flex outward when the bowstring is released from the nock point, causing the bowstring to move forward along the rail.
