A projectile launching device includes self-timing without cam lean. The projectile launching device preferably includes a rail, a riser, two energy storing components, (such as two limbs), two cams, a launch string, and at least two cables. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables are coupled to the first and second cams. A mid-segment of the first and second cables are slidably engaged with the first and second cable pulleys, respectively. The two cams are preferably built as mirror images of each other at a centerline of the rail. The two cams include a launch string track, having identical, but mirrored, upper and lower cable tracks. A stop is formed on each cam to prevent the cam from being able to rotate in a direction opposite the direction of drawing, when the bow is at rest.

A multi-stroke lever action crossbow has two sets of cocking hooks. The first cocking hooks are disposed on cocking links slidingly coupled to a crossbow body. The second cocking hooks are retractable. The second cocking hooks are disposed on a cocking arm, which is pivotally attached to a cocking lever. A retractable handover latch operatively engages the cocking arm. During the first stroke of the cocking lever, the first cocking hooks draw the bowstring past the handover latch, where the bowstring is retained in a partially drawn position. During the second stroke of the cocking lever, the second cocking hooks draw the bowstring past a trigger latch, where the bowstring is retained in a fully drawn position. When the cocking lever returns to its initial closed position, the second cocking hooks and the handover latch are retracted into the crossbow body.

An energy storage system for a bow, the system defined at least in part by a riser, a first and second limb each having a first end coupled to the riser, a first and second wheel disposed at a second end of respective first and second limbs, a first and second power cord each having a first end coupled to the riser and a second end coupled to respective first and second wheels, and a string extending between and coupled to the first and second wheels.

Crossbows are provided having a barrel with one limb and one winding system mounted to each of two opposite sides of the barrel. Each winding system has a limb string connected to one of the limbs and a limb cam about which the limb string can be wound. The limb cams are connected to and positioned apart from arrow string cams by respective interconnects and an arrow string extends across the barrel from an arrow string cam on one side of the barrel to an arrow string cam on the other side of the barrel. The limbs provide first forces urging the limb strings to unwind from the limb cams and the interconnects receive the first forces and convey a second forces to the arrow cams urging the arrow cams to rotate so as to wind the arrow strings onto the arrow cams. The arrow string is drawn against such urging.

A repeating crossbow having a pump-action reloading mechanism. The crossbow includes an elongated body with a shooting track and a holding chamber configured to house one or more projectiles. A hatch is coupled to the body and configured to move between a first position aligned with the shooting track and a second position at least partially aligned with the holding chamber. A palm rest is slidingly connected to the elongated body. Sliding the palm rest in a rearward direction causes the hatch to move from the first position into the second position. A biasing member within the holding chamber ejects a projectile onto the hatch. Sliding the palm rest in a forward direction to return to its default position causes the hatch to return to its first position, bringing the proj ectile into alignment with the shooting track.

The present invention relates to an arrow feeding device for crossbows. The feeding device positions the arrows in the feeding pall. The feeding device includes a feeding part which has a path defined through the top end and the bottom end of the feeding part. The path is defined by two sidewalls and each sidewall of the path includes a rib extending therefrom. The two ribs are located close to the rear end of the feeding part. The arrow includes two grooves defined in the tail thereof so that the two ribs of the path are received in the two grooves of the arrow. The arrow is properly positioned and restricts from shifting in the path so as to improve preciseness of shooting.

A firing system for a crossbow having an arrow rest extending along an arrow rest axis, the firing system having a right limb and a left limb, the right limb being pivotable about a right limb axis and the left limb being pivotable about a left limb axis, the firing system further including a right cam and a left cam, the right cam having a right bow string groove and being rotatable about a right cam axis, the left cam having a left bow string groove and being rotatable about a left cam axis, the firing system having a bow string extending between the right and left cams and extending within the right and left bow string grooves, the bow string positionable between an un-cocked condition and a cocked or full draw condition wherein movement of the bow string from the un-cocked condition toward the cocked condition moves the right and left cams toward each other and pivots the right and left limbs about the right and left limbs axes respectively, the firing system further including a power assembly having a power cable and a spring assembly, the power cable having a forward end operably joined to the right and left limbs and a rear end operably joined to the spring assembly, the spring assembly having a power spring extending along a power spring axis between a first spring end and a second spring end and having a central spring opening, the power spring being below the arrow rest, the power cable extending through the central spring opening from the first spring end toward the second spring end, the rear end of the power cable being operably joined relative to the second spring end of the power spring, moving the bow string from the un-cocked condition to the cocked condition causing the right and left limbs to the pull forward end of the power cable forwardly wherein the operable engagement with the second spring end compressing the power spring by pulling the second spring end toward the first spring end to produce the shooting force to propel the archery arrow.
