Including Cooperating, Relatively Stationary Means For Intermittently Locking Material Or Cable Patents (Class 254/252)
  • Publication number: 20100001242
    Abstract: A cable guide mechanism configured to be releasably attached to a shaft, which includes a body portion, an indent or groove and a protrusion, characterised in that said indent or groove is located on the opposite side of the body portion to the protrusion, and is dimensioned and configured to releasably retain an inside edge of a first distal end of a loop which is attached to a terminal end of a cable; the protrusion is tapered with its widest section directly opposite the indent or groove; the linear distance between the bottom of the indent or groove and the widest section of the protrusion is sufficiently close to the inside length of the loop that in use the first distal end of the loop cannot climb out of the indent or groove; said shaft is configured to freely rotate co-axially inside the cable guide mechanism.

  • Patent number: 7591451
    Abstract: Provided is a tensioning clutch to be used in a tool for tensioning bundle, or cable, ties. A tensioning clutch according to the present invention includes a pawl mechanism having a removable pawl insert adapted to be reoriented or replaced without requiring significant disassembly of the housing of the tool. A tensioning clutch according to the present invention includes a pawl link, a tension abutment at least partly contemporaneously movable with the pawl link, and a pawl mechanism movably coupled to the pawl link. The pawl mechanism includes a pawl insert having one or more tie engagement surfaces, the insert being detachably coupled to a pawl body. The tie engagement surface of the insert may be biased towards, and movable away from, the tension abutment.

  • Publication number: 20080258123
    Abstract: A cardboard baler compacts a bundle of material by drawing the cardboard upwardly towards a compacting bearing member supported by the frame of the baler. The baler is provided with a string, cord or rope tightening mechanism which relies on a hand-actuated ratchet-like mechanism to draw two portions of the rope towards each other so that the rope may be tied to secure a bundle of cardboard. The rope tightening mechanism is supported by the frame of the cardboard baler when it is in use.

  • Patent number: 6494436
    Abstract: A fence wire tensioning tool includes an arm 2 with fixed jaws 7 attached to both sides and a positioning foot 4 which pivots about a bolt 8. At the opposite end of the arm is fixed a movable jaw assembly 1, which extends to form a handle 3. This assembly rotates about a pivot pin 5, which is secured by a hexagonal socket set screw 10. The handle 3 may include a rubber or plastic hand grip 12 which affords a better purchase on the tool by the operator.

  • Patent number: 6105937
    Abstract: A wire clamp device affixed to an outer end of a bar in a wire tightener of the type having a stationary wire holding clamp at an opposite end of the bar. A carrier is mounted on the bar and is also provided with a wire holding clamp. The bar is provided with a jack rack and the carrier has a jack mechanism for forcibly driving the carrier toward the first wire holding clamp so as to pull end portions of two strands of wire held by the two wire holding clamps toward each other. The wire clamp device which also has a wire holding clamp is positioned to hold the strand held by the wire holding clamp of the carrier after it has been drawn towards the first wire holding clamp so that the wire holding clamp on the carrier may be released to allow the carrier to be reset to a position near the wire clamp device, after which the wire holding clamp on the carrier is again activated to grasp again the tightened strand which it had previously held.

  • Patent number: 4889320
    Abstract: A thick-walled housing has a longitudinal hole with an end orifice that runs in the axial direction of the housing. A spring-loaded clamping unit is axially displaceable in the hole. An oblique hole in the housing obliquely opens into the longitudinal hole. The clamping unit clamps a rope fed through the end orifice of the longitudinal hole and emerging through the oblique hole. The clamping unit has an axial projection on each side. The housing has guide slots located opposite one another that guide the axial projections. The ends of the axial projections form handles that pass through and extend beyond the housing. The clamping unit consists of a front and rear roller and a bearing part connecting the rollers one behind the other. The diameter of the front roller is smaller and depends on its forward displacement. The axial projections are provided on the larger rear roller.

  • Patent number: 4425862
    Abstract: A sail line stopper is provided for controlling the hoisting and trimming of sails in which the line may be released under heavy load without abrading the line so released. A U-shaped base member having legs with a pivot pin mounted therein is adapted to be anchored on a sailboat. A cam mechanism includes an inner element having a handle attached thereto which is eccentrically mounted for pivotal movement around the pivot pin. A movable outer element is positioned for pivotal movement and a rotational movement on the eccentrically mounted inner element. One or more springs are mounted between the inner and outer elements of the cam mechanism which are acted on when relative movement takes place between the elements. The spring is compressed when the handle is pivoted placing the outer member in locking engagement with the line in the load direction which locking action is increased with increasing load; while allowing the outer member to rotate or float over the line in the other direction.

  • Patent number: 4368769
    Abstract: A skid-resisting chain adapted to be attached to and removed from the tires of a vehicle with a minimum of effort to provide improved traction in snow, ice, mud or other slippery road conditions. The attachment-detachment means comprises a flexible metal cable adapted to tie the tire chain around the tire and wheel and a biased cam gripping means adapted to frictionally-engage the end of the cable in a manner which provides increased locking action when a withdrawal force is applied to the cable and yet permits easy release when a tightening force or a detachment force is applied to the cable.
