Publication number: 20140283806Abstract: One or more techniques and/or systems are disclosed for 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.Type: ApplicationFiled: June 12, 2014Publication date: September 25, 2014Inventors: Richard L.

Patent number: 8794224Abstract: A crossbow may include a crossbow barrel having reduced weight and increased strength and shock resistance to the crossbow. This invention may also aid in improving torsional resistance, improving specific stiffness, and increasing compresses strength. The invention may also reduce friction between a barrel and a bow string to increase bow string life. The invention may also reduce the friction between a barrel and a bow to allow added arrow distance. Additionally, the crossbow may decrease both vibration and sound.Type: GrantFiled: January 5, 2012Date of Patent: August 5, 2014Assignee: Hunter's Manufacturing CompanyInventors: Richard L.

Publication number: 20130175817Abstract: One or more techniques and/or systems are disclosed for an arrow extractor. The arrow extractor can comprise a first and a second elongated lever that are in rotatable engagement with each other. The respective elongated levers comprise a first end configured to be manipulated by a user, and a second end that comprises a tool configured to engage a first and second part of a gripper. The gripper comprises an elongated cavity that can be configured to grip the shaft of an arrow. The first tool and the second tool are engaged with the gripper, and when the user applies a grasping force to the first end of the respective levers, the grasping force may also applied to the gripper, thereby gripping the shaft of the arrow, which may then be extracted from an object using the levers.Type: ApplicationFiled: December 18, 2012Publication date: July 11, 2013Applicant: Hunter's Manufacturing Company, Inc., d/b/a TenPoint Crossbow TechnologiesInventors: Richard L.
