Abstract: A fluid actuated tool for securing together sheet metal parts comprising a power pack unit including a piston and cylinder assembly to which there is connected a jaw housing having a pair of complementary jaw members that are actuated between operative and inoperative positions by a ram connected to a piston reciprocally mounted in the cylinder of the power pack unit. The respective jaw members include complementary work engaging portions in the form of a piercing blade and complementary blade slot which function to pierce the metal parts and curl the displaced metal to positively secure the metal parts together. A valve is disposed in the power pack unit to control the flow of actuating fluid to and from the cylinder to effect the displacement of the piston to activate the jaw member, and a handle is connected to the power pack unit to facilitate the operation thereof.

Abstract: A fluid actuated orthopedic tool for cutting away degenerated or torn cartilage which includes a housing having a piston chamber in which a piston is reciprocally mounted and an associated head portion. The head portion includes an elongated tubular guide having a fixed cutter member connected thereto, and through which there extends a rotatable shaft having a movable cutter member connected thereto. The rotary shaft is driving connected by a pinion to a piston rack so that the displacement of the piston by fluid pressure and spring return effects the actuation of the movable cutter member to effect a cutting action. A lock is provided to lock the cutter members, and an internal adjustment is provided to adjust the stroke of the piston. Also, a valve means and associated actuator is provided to control the flow of actuating fluid to the piston chamber.

Abstract: A terminal block installation tool which comprises a housing having a driving and cutting bit actuated by a piston ram which can be either manually actuated mechanically or pneumatically actuated by fluid pressure.

Abstract: A fluid actuated tool for effecting a positive predetermined crimping or cutting operation on a work piece having a bleed arrangement which will prohibit the tool from completing its complete cycle of operation if the pressure of the actuating fluid falls below a pressure sufficient to effect a desired cut or crimp.
