Abstract: A tool for attaching and removing threaded fittings of the type typically used to attach hoses, such as hydraulic hoses, characterized by an extended longitudinal body which is open along a length of the body to accept a hose which has a fitting on it. An adaptor is mounted on an end of the body. The adaptor accepts and rotates a fastener which is part of the hose fitting, such as a six point fastener. The adaptor has an open portion to accept the hose. The opposite end of the body accepts a drive tool, such as a ratchet or a pneumatic wrench.

Abstract: A torque transfer device allows torque to be input at one point of the device and transferred to another point of the device, at which the power or torque is taken from the device. The device incorporates a continuous direct drive comprised of a plurality of individual, and unconnected, pins which advance each other to provide the drive. The pins have enlarged ends and reduced centers. The centers of the pins ride on a centrally disposed shedder which acts as a guide rail. The direct drive communicates with the drive sprockets, traveling through the drive sprockets to rotate the drive sprockets to transfer torque.

Abstract: A torque transfer device allows torque to be input at one point of the device and transferred to another point of the device at which the power or torque can be taken from the device. The device incorporates a direct drive means comprised of links and spacers which are interconnected by a continuous loop, such as a cable. The direct drive means drives gears which are constructed to receive the links and spacers.

Abstract: A torque transfer tool which allows a torque input at one point of the tool, with the torque transferred to another point of the tool. Gears are connected by a direct drive means, contained within an elongate housing having a dog bone shape which is formed by gear housings on opposite ends of the elongate housing which are connected by a central housing. Chain guides are present on the interior of the housing where the gear housings join the central housing.

Abstract: A torque transfer device allows torque to be input at one point of the device and transferred to another point of the device at which the power or torque can be taken from the device. The device incorporates a direct drive means comprised of a plurality of links having an arcuate shape of constant radius which form a continuous loop, with alternating links having an orifice. The direct drive means drives gears which have teeth which protrude into said orifice.
