TL;DR: In this paper, the crossbow bowstring drawing mechanism can be manually operated or motorized, and can be manufactured as part of a crossbow or retrofit into a cross bow.
Abstract: Crossbow bowstring drawing mechanisms which are integrated into or secured in the crossbow handle and which provide a straight and balanced draw to the crossbow bowstring to cock the crossbow bowstring in position in the crossbow trigger mechanism ready for firing. The cocking system can be manually operated or motorized, and can be manufactured as part of a crossbow or retrofit into a crossbow. An internal or external source of rotational power, such as hand crank, power screwdriver or an electrical motor, is preferably utilized in conjunction with a claw member including a bowstring engaging portion to translate rotation of the input source to longitudinal movement of the claw member to draw or release the crossbow bowstring resulting with minimal effort being expended by the user. The claw member may include adjustable cams used to center the claw member with respect to the crossbow barrel.

30 Mar 1992TL;DR: An apparatus for cocking a conventional crossbow, the crossbow having a stock with a first end and a second end, is described in this paper, which consists of a pair of pulleys that are removably attachable to the string of a crossbow and a cord extending through one pulley, about the second end of the stock and through the other pulley.
Abstract: An apparatus for cocking a conventional crossbow, the crossbow having a stock with a first end and a second end. The apparatus comprises a pair of pulleys that are removably attachable to the string of the crossbow, and a cord extending through one pulley, about the second end of the crossbow stock and through the other pulley, so that by pulling the opposite ends of the string the bow may be cocked.

TL;DR: In this article, a modular cam system for an archery bow or crossbow includes swappable cams that change the maximum draw weight of the archery Bow or Crossbow.
Abstract: A modular cam system for an archery bow or crossbow includes swappable cams that change the maximum draw weight of the archery bow or crossbow. Moreover, the modular cams can be affixed to a rotatable member in a number of orientations to set the desired draw length without changing the limbs, tightening or loosening limb bolts, or disassembling the bow. Further, the maximum draw weight of the bow remains substantially similar throughout a large portion of the draw length adjustment for a specified cam module.

TL;DR: In this paper, a crossbow may include a main beam, a compound bow assembly mounted to the main beam and a trigger mechanism mounted on the trigger for holding a bowstring in a cocked position.
Abstract: A crossbow may include a main beam; a compound bow assembly mounted to the main beam; and, a trigger mechanism mounted to the main beam for use in holding a bowstring in a cocked position. The crossbow may include wheels at opposite ends of the bow that operatively receive the bowstring. The wheels may be separated by a wheel distance (WD) when the crossbow is in an un-cocked position. The crossbow may also have a power stroke distance (PD) and the ratio WD/PD may be less than 2.0.
