Patent number: 11254551Abstract: An apparatus for controlling tension in a pulling rope that is attached to a flying, unmanned aerial device or drone may utilize a cylinder around which the rope is wound, a shaft that longitudinally passes through the cylinder, a disc brake rotor that is mounted to the shaft, a brake caliper that is mounted circumferentially at a periphery of the disc brake rotor, and a brake lever that tensions a cable that is attached to, and movable to control movement of, the brake caliper, which may be hydraulic, against surfaces the disc brake rotor. The brake lever may be hand actuated and mounted to a handlebar. A frame may be part of the apparatus and support apparatus components and may have a protruding hitch portion that inserts into a vehicle's receiver hitch. An adjustable pulling rope guide support through which the rope is threaded, mounts to the frame.Type: GrantFiled: January 15, 2019Date of Patent: February 22, 2022Assignee: Quanta Associates, L.P.Inventors: James Alan Fulk, II, David Wendell Lapham, Timothy Dean Nutz
