  • Patent number: 6945145
    Abstract: A quick action, cam operated hand tool holder, such as a tap wrench. The cam is moveable between at least one released and one locked positions, preferably by a conventional T-handle. A third position may also be provided which may be either a second locked or a second released position. An adjustable nut, or similar, retains a collet within the wrench and adjusts the wrench to different sizes of tools (i.e. taps) and adjusts the gripping force applied when the cam is locked. The collet is preferably reversible, accommodating different tool sizes on each end, but may also be single ended.

  • Publication number: 20050050734
    Abstract: A utility knife using segmented, snap-off blades, or snap knife, incorporating an improved means for snapping off the dull segments. A two part handle is pivotally interconnected so that when closed, a standard handle is formed. When open, the two parts of the handle are aligned opposite each other. The blade, contained in one part can be advanced to enter a slot in the other part. With the segment line of the blade aligned in the gap between the two parts, the blade can be snapped by closing the handles. The snapped segment is preferably retained within the handle for later disposal.

  • Patent number: 6708588
    Abstract: A self adjusting closure mechanism for a locking plier or similar device. Central to the invention is a set of one or more friction pawls which slide along a support rod, moved by a push link working against a spring. The push link is free to rotate between two positions relative to the rod as it slides. In the first position, and in between the positions, the push link bears against the center of the friction pawls and they remain free to slide along the rod. When the push link rotates to the second position, it presses on the edge of the pawls, causing them to tilt, coupling to the rod and preventing movement along the rod. In a typical locking plier, the support rod is mounted to the frame and the opposite end of the push link connects to the handle. As the handle closes, the push link rotates towards its second position and optionally slides along the support rod. When the friction pawls lock, the plier begins to grip and lock on to the work piece.

  • Patent number: 6626071
    Abstract: A multi-functional hand tool assembly includes a handle with tool attachments. The handle has opposite ends with opposite holes extending therethrough. The tool attachments are removably, interchangeably and reversibly insertable into the handle ends and each has a middle section and end tool sections connected to and extending in opposite directions from opposite ends of the middle section. Each middle section is identical to one another and has a continuous exterior surface which matches a continuous interior end surface defining each hole in a handle end such that the middle sections can snugly fit through the hole in either handle end so as to mount the tool attachments in non-rotatable relationships with the handle ends such that the tool attachments will turn with turning of the handle.

  • Patent number: 6363560
    Abstract: A compact multi-function installer's tool which combines a linear compression tool for type F fittings with at least one of a security wrench, a trap wrench, and a hex socket wrench. The wrenches are preferably aligned with the central axis of the compression tool and the compression tool handle can be extended substantially perpendicular to the tool so that it operates as a single sided T handle for the wrenches, increasing the amount of torque which can be applied. Ideally at least two of the wrenches are included in the tool. The seat for the compression tool is preferably combined with one of the wrenches, sharing the end of the tool and the clearance slot therein. In one embodiment, the body of the tool is generally cylindrical and the compression tool handle recesses at least slightly into the body, so that the body functions similarly to a conventional nut driver handle, for ease of use.

  • Patent number: 6314779
    Abstract: A tool for reducing the diameter of the center conductor of a coaxial cable allowing it to mate with a smaller receptacle without the necessity of a reducer. The tool uses plural rollers within a housing to roll form the conductor as they rotate about it. Preferably the rollers are caged for alignment but bear on the inner surface of the housing. The housing thus resists the axial loads on the rollers and transmits the rotational drive force directly to the rollers allowing the roller cage to serve solely alignment purposes. The roller cage incorporates an extended nose designed to contact the dielectric portion of the cable, serving as a depth stop. An optional indicator sleeve is visible through openings in the housing and indicates the position of the roller cage within the housing. A small lead angle on the rollers causes them to self feed onto the conductor and to crawl rearward within the chamber which provide the indication of the length of conductor reduced.

  • Patent number: 5927802
    Abstract: A bicycle seat employs a suspension platform that provides yieldable flexible support of the weight of a bicyclist through contact primarily with the buttocks rather than the crotch of the bicyclist. The suspension platform is formed by a triangular-shaped flexible membrane attached to and extending over and between rigid rear cross and front nose support members mounted respectively to a front end and a pair of rear ends of a U-shaped frame member such that the membrane is held in a taut flat condition under tension so as to provide the flexible support of the bicyclist's buttocks. The membrane is constructed of an inelastic fabric material having a pair of opposite side wing sheets and a longitudinal central band all made of longitudinal strands extending parallel to one another and held together by cross strands interwoven with the longitudinal strands.

  • Patent number: 5927738
    Abstract: A seat suspension system for a bicycle comprises an outer generally elongate hollow tube and an inner generally elongate hollow tube telescopingly received within the outer tube. Ball bearing races are provided as by metal forming in the inner and outer tubes, and ball bearings are disposed in the races. The inner tube has an inner end fitted with a bushing such that the bushing is slidingly engaged with the outer tube. A compression spring is disposed between the inner end of the inner tube and a stop pin extending through the outer tube. The bearings and bushing cooperate to permit longitudinal movement of the inner tube within the outer tube but prevent relative lateral and rotational movement of the tubes. By this construction, a seat suspension system can be constructed with standard readily available materials and without costly manufacturing procedures yet will provide a highly functional and reliable product.

  • Patent number: 5596800
    Abstract: A crimping tool for connecting a cable fitting to the end of a coaxial cable is made up of one or more die members having tapered die surfaces, a chuck which is axially spaced from the die surfaces to support the fitting in loosely assembled relation to the end of the cable, and a handle operates through a ratchet mechanism to cause axial movement of the chuck toward and away from the die surfaces and axially force the fitting into the die cavity so as to uniformly reduce the circumference of one end of the fitting into a generally conical configuration snugly engaging the cable.
