Abstract:
A device and reversible drill, in combination, for use in operating a multi-speed trailer landing gear drive mechanism, which device comprises:an elongated, rigid, cylindrical body having a closed end portion which is coupleable to a rotatable drive shaft of the drill, and an open end portion which is adapted to releasably grip the end of a crank shaft of a mechanical landing gear drive mechanism, such that when the drive shaft of the drill rotates, the device rotates, causing the crank shaft of the mechanical landing gear drive mechanism to rotate or when the drive shaft of the drill is moved in or out axially along the axis of rotation of the crankshaft of the landing gear drive mechanism, the device also moves in or out, causing the crankshaft of the landing gear drive mechanism to move in or out, thus effecting the raising or lowering of one or more landing gear legs of a vehicle trailer, or speed selection,the open end portion of the device comprising two identical T-shaped slots on opposite sides of the open end portion, the T-shaped slots being adapted to releasably grip the end of the crank shaft as the crank shaft rotates in either direction to raise or lower the landing gear, or pushes in or pulls out to select a speed;the closed end portion of the device comprising at least one threaded hole or shaft, which is coupleable to the drill, so that the device stays on the drill during use and can be removed from the drill when not in use, and further comprising a machined shoulder, which provides a stop as the device is tightened onto the drive shaft of the drill; andwherein the device requires no permanent alterations to the vehicle trailer; the mechanical landing gear drive mechanism is a multi-speed manual crank system without the manual crank, which is capable of raising or lowering two landing gear legs on a vehicle trailer; and the drill drive shaft, which is threaded, is screwed into the threaded hole in the closed end portion of the device, and the device is removably locked onto the drill drive shaft by means of a locking screw which passes through a nonthreaded hole in the device and into a threaded hole in the drill drive shaft.
