Abstract: An adjustable trigger mechanism assembly for a crossbow includes a trigger housing, a sear lever, a latch, trigger lever, and a linkage arm. The sear lever is pivotally engaged with the trigger housing and controls the movement of the latch. One end of the linkage arm is pivotally engaged with the sear lever. The trigger lever is pivotally engaged with the trigger housing. The trigger lever includes at least two moment arm holes for pivotally engaging an opposing end of the linkage arm. In an alternative embodiment, the at least two moment arm holes are formed in the sear lever. The at least two moment arms cause the trigger lever to have at least two different pull distances and pull forces.

Abstract: An improved crossbow lock mechanism assembly includes a trigger housing, a seer lever, a seer lock lever, a latch, trigger, a spring, a detent ball, and a safety slide bar having one ball detent. Selectively positioning the safety slide bar in a safe position, the spring forces the detent ball into a safety detent notch, which holds the safety bar in safety position, thus preventing movement of the seer lever. Selectively positioning the safety slide bar in a fire position results in the spring creating friction between the ball and safety bar, thus holding safety bar in place and allowing movement of the seer lever. A second embodiment uses a pivoting safety lock lever. The engagement of the seer lever with the string latch is indirect, because of a roller pin spaced therebetween. A third embodiment includes a safety slide bar, which makes indirect contact with the seer lever.

Abstract: A projectile launching device includes self-timing without cam lean. The projectile launching device may include a rail, a riser, two energy storing components, (such as two limbs), two cams, a launch string, and at least one cable. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables may be coupled to the rail or riser. A mid-portion of the first and second cables are slideably engaged with the first and second cams, respectively. Alternatively, a single cable may replace the first and second cables. 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.

Abstract: A self-centering anti-dry fire device for a crossbow n improved crossbow lock mechanism assembly includes a trigger housing, a string latch, a seer lever, a combination arrow self-centering anti-dry fire and seer lock lever, a trigger and a safety slide bar. An arrow cavity is formed in a top of the combination arrow self-centering anti-dry fire and seer lock lever. A cross section of the arrow cavity may have a “V” shape, a curved shape, a notch shape or any other suitable shape. The arrow cavity ensures that the arrow shaft is centered relative to a centerline of a barrel of the crossbow.
