Abstract: A battery powered hydraulic tool including a frame; a battery connected to the frame; a motor connected to the frame and adapted to be powered by the battery; and a hydraulic pump connected to the motor by a gear reduction transmission. The motor and gear reduction transmission are adapted to output a torque of the least about 160 oz-in with the gear reduction transmission being adapted to provide a gear reduction of between about 8:1 to about 15:1 or less, and the hydraulic pump being adapted to output at least about 6000 psi of pressure or more.

Abstract: A powder operated tool including a frame, a tool body and a reusable combined cartridge holder and ram rear end receiver. The frame includes an anvil section. The tool body is adjustably connected to the frame. The tool body comprises a ram, and a breech assembly connected to a rear end of the tool body. The breech assembly includes a striker, a breach pad and a firing pin. The reusable combined cartridge holder and ram rear end receiver is removably connected to the tool body.

Abstract: A collapsible tool includes at least one handle having first and second handle portions and hinge that allows the tool to benefit from the leverage and mechanical advantage of a full-size tool, yet is easily and quickly collapsible and extendable. In one embodiment, the first handle portion includes one or more spring-biased detents that contact engagement portions (preferably semi-circular surfaces) disposed on the second handle portion and secure the handle in the extended position. A pivot is disposed through the handle portions in the direction of the force moment produced during use. Alternatively, the first handle portion includes a base having three supports, a cavity, and a biased tab disposed within the cavity. The second end includes a bevel region and a notch region. In the extended position, the biased tab engages the notch region and secures the second handle portion between the biased tab and the supports.
