Abstract: A crossbow includes a center rail defining a firing plane. First upper and lower flexible limbs are coupled to the center rail and include first free ends. Second upper and lower flexible limbs are coupled to the center rail and include second free ends. A first cam assembly is rotatably coupled to the first free ends. A second cam assembly is rotatably coupled to the second free ends. A draw string is coupled to the first cam assembly and the second cam assembly and extends across the center rail. First upper and lower power cables have first ends coupled to the first cam assembly and second ends coupled with the second upper and lower flexible limbs, respectively. Second upper and lower power cables have first ends coupled with the second cam assembly and second ends coupled with the first upper and lower flexible limbs, respectively.

Abstract: A crossbow includes a frame, a riser coupled to the frame, a first flexible limb, a second flexible limb, a third flexible limb, and a fourth flexible limb. A first cam assembly couples to the first flexible limb and the second limb and includes a first draw string journal, a first power cable journal, and a second power cable journal. A second cam assembly couples to the third flexible limb and the fourth flexible limb and includes a second draw string journal, a third power cable journal, and a fourth power cable journal. A draw string is received in the first draw string journal and the second draw string journal. Power cables cross over the center rail, above and below the draw string, and are received in the first power cable journal, the second power cable journal, the third power cable journal, and the fourth power cable journal, respectively.

Abstract: A crossbow including a frame with a riser and a center rail. First and second flexible limbs are attached to the riser. A draw string is received in string guide journals in first and second cams rotatably attached to the frame. The draw string unwinds from the string guide journals as it translates between a released configuration and a drawn configuration. The first and second cams include at least first and second power cable take-up journals, respectively. At least first and second power cables are attached to the first and second limbs and received in the first and second power cable take-up journals, respectively. As the crossbow is drawn from the released configuration to the drawn configuration the first and second power cables wrap onto the respective first and second power cable take-up journals.

Abstract: A high impact strength lighted nock assembly for an arrow that is activated when the arrow is fired with a bowstring. The lighted nock assembly includes a nock molded from a high impact strength, transparent polymeric material containing at least 10% by weight reinforcing fibers. The nock includes a head configured to engage with the bowstring and a shank configured to couple with a rear end of the arrow. The shank includes a recess extending in a distal end of the shank toward the head. A light assembly including a light emitting device is located in the recess in the shank that is electrically coupled to a battery. A switch is electrically coupled to the light emitting device and the battery that is triggered when the arrow is tired to activate the light emitting device.

Abstract: A dual-cam archery bow with simultaneous power cable take-up and let-out journals. Each cam has power cable journals located on opposite sides of the draw string journal, where at least one of power cable journals is a helical journal.

Abstract: A crossbow including first and second flexible limbs attached to a center rail. A first cam is mounted to the first bow limb and rotatable around a first axis. A draw string is received in string guide journals and is secured to first and second cams. The draw string unwinds from the string guide journals as it translates from a released configuration to a drawn configuration. Power cables are received in first and second power cable take-up journals on each of the first and second cams. As the crossbow is drawn from the released configuration to the drawn configuration the first and second power cables wrap onto the respective first and second power cable take-up journals and are displaced along the first and second axes away from the first and second planes of rotation of the first and second draw string journals.

Abstract: A crossbow including pulleys rotatably attached to a center rail of the crossbow. Power cables of the crossbow connect the limbs of the crossbow to the pulleys. The draw string is enclosed in a safety cover. The crossbow includes a cocking system that translates a string carrier along the center rail to cock and de-cock the crossbow.

Abstract: A method of engaging an arrow with an anti-dry fire system on a crossbow and an arrow assembly for crossbow that engages the anti-dry fire system behind the draw string. Matched weight arrows having lighted and non-lighted nocks are also disclosed.

Abstract: A crossbow string guides that include upper and lower helical power cable journals on opposite sides of a draw string journal. A separation between first and second axis of the string guides in a drawn configuration is about 5 inches to about 10 inches and the draw string in the drawn configuration comprises an included angle of less than about 25 degrees. First and second pairs of power cables wrap and unwrap at least 300 degrees around, the respective first and second upper and lower helical power cable journals as the draw string moves between a released configuration to a drawn configuration.

Abstract: The present disclosure is directed to a crossbow having first and second limbs with distal portions pivotally coupled to the frame at distal limb mounts and proximal portions pivotally coupled to the frame at proximal limb mounts. First and second cams are attached to the first and second limbs at locations between the distal portion and the proximal portions. A cocking mechanism slides on the center rail to engage with a draw string in the released configuration and slides to a retracted position to move the draw string to the drawn configuration and to engage with a trigger assembly.

Abstract: A reduced length crossbow with a trigger located near a midpoint of the crossbow and a small included angle of the draw string when in the drawing configuration that creates a space between the draw string and the user's face. The included angle of the draw string when in the drawing configuration may be less than about 25 degrees. The trigger is typically located proximate the midpoint within about 10% of the overall length of the crossbow.

Abstract: A system for cocking mechanism for a crossbow that uses an elongated handle pivotally attached to the center support to move a traveler engaged with the draw string from a release configuration to a drawing configuration and into engagement with a trigger assembly. A ratcheting mechanism prevents the elongated handle from moving toward the open configuration as the crossbow is being cocked.
