The nock may include a connection surface designed to connect the nock to the associated arrow and string guide impressions that may be designed to receive a bowstring to fire the associated arrow from the associated bow.

Abstract: An arrow nock may have at least two distinct string guide impressions each designed to receive a bowstring to fire an arrow from a bow. The nock may be operable when connected and aligned with the arrow to cause the bowstring to be received within at least one of the string guide impressions to fire the arrow. As it is received within the string guide impression, the bowstring may cause the arrow to rotate about its longitudinal axis.

Abstract: A crossbow in some embodiments may include two power cables and two power cable wheels. Each power cable may extend from a bowstring wheel, to a power cable wheel and then back to the bowstring wheel. A crossbow in some other embodiments may include four power cables and two power cable wheels. Each power cable may extend from a bowstring wheel, to a power cable wheel and then to a portion of the crossbow that does not move relative to the main beam.

Abstract: An arrow nock may have at least two distinct string guides each designed to receive a bowstring to fire an arrow from a bow. When the nock is connected to and aligned with the arrow, each distinct string guide may be designed, when receiving the bowstring, to rotate the arrow about its longitudinal axis with respect to the bow into one of a limited number of alignment orientations.

Abstract: A crossbow cable saver may have a cable engagement portion designed to engage at least one crossbow cable and a main beam engagement portion designed to engage the crossbow main beam. The cable saver may be operable to pivot with respect to the main beam between a first position where a first surface of the main beam engagement portion contacts the main beam and the second surface does not; and a second position where the second surface contacts the main beam and the first surface does not.

Abstract: A portable device for drawing the bowstring of a crossbow. The cocking device may be designed to prevent the uneven drawing of the crossbow and may eliminate the complex installation process typically required to retro-fit an existing crossbow with known cocking devices.

Abstract: An arrow nock may have three or more string guide impressions that are designed to receive a portion of a bowstring to fire an arrow. Each string guide impression may be defined by two circumferentially spaced walls separated by a floor. The walls and floors may be curvilinear in shape. The walls may have sides and a peak that are curvilinear. The walls may have widths that narrow toward the peak. The walls may have a radial length that is at least one fourth of the nock outside diameter.

Abstract: An alignment tool may be used with an arrow and a nock. The alignment tool may include a tool body, a connection member, and an opening. The alignment tool and nock may be rotatable with respect to the arrow when the nock is connected to the arrow and the connection member is connected to the nock to align the nock with respect to the arrow by aligning the opening in the tool with an arrow vane with the vane visible through the opening in the tool.

Abstract: One or more techniques and/or systems are disclosed for a nock device that may be used on an arrow. A top portion a nock device can comprise one or more pairs of string guide impression on its top surface, where the respective one or more pairs of string guide impressions may be symmetrically arranged on the top surface, with respect to each other. A first pair of string guide impression can be disposed along a first bisecting line on the top surface, and, if present, a second pair of string guide impressions can be disposed along a second bisecting line on the top surface. The respective one or more pairs of string guide impression can be configured to receive a bowstring, where the first pair may receive the bowstring in a first orientation, and the second pair, if present, may receive the bowstring in a second orientation.

Abstract: An alignment tool may be used to align a nock with respect to an arrow having vanes. The alignment tool may include a body, a connection member extending from the body, and indicating surfaces that are spaced around the outer surface of the alignment tool body at a relative angular orientation that matches the angular orientation of the arrow vanes. The connection member may be attached to the nock and then both the tool and the nock may be rotated with respect to the arrow to align the nock with respect to the arrow by aligning the indicating surfaces with respect to the vanes.

Abstract: A grip guard may be used with a crossbow that has a main beam including a stock and a barrel. The grip guard may have a first wall that is positioned between the stock and the barrel and a second wall that extends outwardly from the main beam. The first wall may have dampening properties to attenuate sounds and vibrations caused by firing the crossbow and the second wall may prevent a user's fingers from inadvertently extending from the handle toward the barrel.

Abstract: A crossbow limb pocket for use in mounting a bow limb to a crossbow may include an inner limb pocket component and an outer limb pocket component. One of the components may have at least one groove while the other has at least one key. The key may be received within the groove to prevent relative rotational movement of the components when the crossbow is operated.
