    Abstract: A pneumatic metal-work tool includes a punch assembly mounted on the front end of a hydraulic push-rod assembly. The hydraulic push-rod assembly has a hydraulic chamber mounted with a piston rod. One end of the piston rod is mounted in a center hole of a piston. When the control valve of the metal-work tool has a high pressure air entered the casing to drive the piston to move, the pressure air will be converted into a hydraulic force via the hydraulic chamber so as to have the hydraulic push rod provide a punch force, and to have a metal sheet in the opening of the punch assembly punched with a hole.

  • Patent number: 6671966
    Abstract: A hydraulically and/or pneumatically actuated cutting tool is provided having a housing with a piston assembly slidably disposed between a fluid inlet and a fluid outlet. The piston assembly comprises a seal which is operable between two positions. In a first position the seal produces a substantially water-tight seal between the piston and the interior surface of the housing. As a result, fluid entering the chamber through the fluid inlet advances the piston assembly toward the fluid outlet. In a second position a gap is formed between the seal and the interior surface of the housing such that fluid communication is established between the fluid inlet and the fluid outlet. As the fluid is removed from the housing through the fluid outlet, a spring biases the piston assembly back to its original resting position.

  • Patent number: 6295991
    Abstract: A cigar cutter and lighter storage device for cutting off an end of a cigar is disclosed. The device has a tubular body with a first end for receiving a disposable lighter and a collar which removably secures the lighter within the body. A cutter element is secured in a second end of the tubular body. The cutter element has first and second opposed side elements and a cutting member, or knife, pivotally engaged between the first and second side members. The first and second side members define an opening for receiving the end of the cigar. The cutting member is pivotally rotated from a first, or open, position to a second, or closed, position in an arcuate manner through the opening, whereby the end of the cigar is cut.

  • Publication number: 20010002565
    Abstract: The invention is a tool for shortening threaded fasteners which does not compromise the structural integrity of the cut end or its surrounding threading. The device comprises a c-shaped plate with blade retaining grooves having a plurality of threaded bores sized to match common commercially available fastener diameters, and a blade having a striking end and a cutting edge with an angle of preferably less than 30°. Fasteners to be cut are rotatably threaded in a clockwise direction through the threaded bores so that the portion to be cut extends through the plate. The blade is then inserted into the blade retaining grooves with the cutting edge resting on top of the uppermost fastener to be shortened. Pressure is applied to the striking end with a striking tool such as but not limited to a hammer, which causes the blade to move downward while severing the extended portion of the fasteners to be cut.

  • Patent number: 6108913
    Abstract: A stripping tool for removing clothing, and the like, in emergency situations. The present tool allows for clothing to be stripped from a patient quickly, safely, and efficiently. The stripping tool may be pulled toward the operator of the tool for quickness and ease of use. A handle provided to be used within the operators palm creates an ergonomic, comfortable grip. The handle allows a blade to be pulled upward in a scissoring motion to start a cut in fabric. Therefore, thicker, and heavier fabric may be removed since an initial cut may be made.

  • Patent number: 5956801
    Abstract: An improved articulated wiper blade assembly includes a wiper blade sub-assembly having a female and male spline portions, and an internal stake located within the spline channel for preventing longitudinal movement of the male spline within the female spline channel while still permitting journaled rotation of the male spline within the female spline. The stake is preferably located adjacent to one end of the wiper blade sub-assembly, whereby the wiper blade sub-assembly can be cut at the opposing end thereof to a shorter length without affecting the stake. The stake extends inwardly from the female spline channel into a transverse notch preformed in the body of the male spline and engages the inner walls of the notch to prevent longitudinal movement in either direction. However, the notch still permits rotation of the male spline around the stake. Additional staked fingers and corresponding notches can be utilized to further prevent longitudinal movement of the male spline.

  • Patent number: 5711078
    Abstract: A tool for severing or crimping a workpiece includes a rigid mainframe having an elongate grooved channel running through most of its length. A wedge-shaped upright rigid head forms the front portion of the mainframe. The rear portion of the mainframe has an integral shaft guideway and a mount for mounting a hydraulic cylinder and components. The head and hydraulic mount form a U-shaped jaws area. The upright head has an elongate vertical slot. A cutting or crimping blade can reciprocate along the grooved channel of the mainframe and enter the head so that the blade can fully sever a workpiece placed in the gap between the blade and head. The blade can be a pointed V-shaped cutting blade or a flat crimping blade having a blunt leading edge. The base of the blade has a flange for cooperating with the grooved channel for guiding the blade. The blade is manipulated by a hydraulic piston which is positioned in a hydraulic cylinder mounted at the rear portion of the mainframe.
