  • Patent number: 11629928
    Abstract: A cranking mechanism preferably includes a planetary gear, a drive shaft, a one way bearing, a clutch assembly, and at least one drive unit. The clutch preferably includes a clutch pressure plate, a flywheel, friction surfaces and at least one friction plate. Each drive unit includes a carrier, a spool and a flywheel. The one way bearing and the clutch assembly are axial on the drive shaft. A pressure locking nut is threaded on to a threaded end of the crank shaft to exert pressure on the clutch assembly. The sun gear is fixed on the drive shaft. The at least one drive unit is axial with the drive shaft, and fixed with the carrier of the planetary gear set. The pressure locking nut is tightened against the clutch assembly to frictionally engage the drive shaft with the at least one drive unit.

  • Patent number: 11499792
    Abstract: 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.

  • Patent number: 10458743
    Abstract: A crossbow with built in cocking device includes a manual crank and a built-in, removable motor gearbox assembly and power source. Rotational forces applied to a drive shaft rotate in a first direction, causing first and second string carriages to engage a bow string, moving the bow string towards a string catch. Once the string catch is latched to the bow string, a drive shaft is rotated in a second direction to move first and second string carriages to the a rest position.
