  • Patent number: 6058575
    Abstract: A cable clamp may be constructed from a hollow body, a wedge-shaped member and a means for dislodging the member from the body. The body includes a tapered channel that is sized and shaped to accommodate the member and round, flat or rectangular cable sections. The means for dislodging the member include an aperture extending from one side of the member to the other, at least one cylindrical bearing surface positioned at the upper end of the body, and a camshaft. The camshaft has at least one cylindrical end with an inward facing end and an outward facing end. A cylindrical shaft in orthogonally and eccentrically mounted to the inward facing end. The camshaft is positioned so that the cylindrical shaft will bear against the inner surface of the aperture and the end portion will bear against the bearing surface. When the camshaft is rotated, the cylindrical shaft will cause the aperture and the wedge-shaped member to be displaced upwardly from the body.

  • Patent number: 5987712
    Abstract: An improved cord lock provides a mechanism for preventing a moveable slide from being drawn too far into a cord lock body by heavy forces transmitted through the cord being locked. The improved cord lock has a body of standard manufacture, and a moveable slide which has been modified to provide a positive stop to prevent the slide from entering too far into the body. The positive stop may be formed as a number of projections from the moveable slide which make its overall cross section too large to fit within the lock body.

    Abstract: A serpentine shaped wire clip is disposed in a tapered bore of a housing for axial displacement in the bore and has in a preferred embodiment three U-shaped loops interconnected by end portions. The clip has a bore dimensioned for receiving a cable or rod in radial resilient compressive engagement along the clip entire length which engagement causes the clip to axial displace with the displacement of the cable or rod. The axial displacement of the clip in the tapered bore wedges the clip to the housing and cable or rod locking the elements. The clip may have any number of loops and wire diameter. Also, the housing may have a cylindrical bore and the tapered region may be formed on a rod or bar. The clip may be locked to smooth and grooved surfaces including threads. The housing and rod each have a different one of a cylindrical surface and tapered surface. The clip radially grips the cylindrical surface while wedging in response to relative displacement of the tapered surface to the cylindrical surface.

    Abstract: This invention provides an improved cable clamp construction for telecommunication cables such as coaxial cables made from continuous filaments of optical glass fibers which are surrounded by an annulus of aramid material and contained within an outer plastic jacket. In order to provide intermediate gripping action on the continuous cable without its interruption, the gripping action must be carefully controlled and distributed over a relatively sizable intermediate area of the cable to prevent damage to the fragile fibers of the cable over a long useful life in varying climatic conditions. The gripping clamp is comprised of a limited number of components which are capable of surrounding and gripping the cable without undue flexure, the clamp being comprised essentially of a separable sleeve member and a separable plug member, both of which have tapered surfaces to positively secure the cable with compressive forces over a localized area.

  • Patent number: 5226216
    Abstract: A clamp assembly with a releasable bail for securing and suspending cables, drop wires or the like that utilizes a locking structure cooperating with an aperture in a tail of the clamp assembly to secure and lock the releasable free end of the bail to the clamp assembly. Preferably, the locking structure is a foot segment and head at the end of a leg of the bail with a reduced portion permitting passage of the foot segment from an entry portion along a connecting portion to locate the head at a lock portion. Additionally, the other leg of the bail can be slideably attached utilizing an interlocking structure that reduces bail deformations during installation. Furthermore, the present invention provides a method for assembling the cable clamp assembly wherein the first and second legs are assembled and attached to the tail, and also providing a method for simultaneously forming the reduced portion of the second leg and a deformed region in the tail to capture the first leg in the tail.

  • Patent number: 5159861
    Abstract: A lockable wire guide control handle for grasping and manipulating a wire guide. The control handle includes an elongated member and a thumb slide positioned in a retention channel formed in the distal portion of the elongated member. The proximal portion of the elongated member is cylindrical having an enclosed passageway extending longitudinally therethrough, which is offset for passage of the wire guide therethrough. The distal portion of the elongated member includes a dovetail-shaped retention channel, the bottom surface includng an inclined slot for positioning the wire guide therein. The thumb slide includes a mating dovetail-shaped tenon positioned in the retention channel. Extending from the flat surface of the dovetail-shaped tenon is an inclined projection for fixedly positioning the wire guide in the inclined slot. The inclined slot and projection have a variable, uniform spacing therebetween for fixedly positioning various diameter wire guides therein.

  • Patent number: 5137517
    Abstract: A device for gripping a medical shaft such as a guide wire or catheter tube has two operative components: a body member with a longitudinal slot for receiving the shaft and an insert member slidably received in the slot of the body member. The body member and insert member have opposed, generally parallel shaft engagement surfaces which extend longitudinally along the shaft on each side thereof. Moving the insert member longitudinally relative to the body member activates a slide arrangement which moves the opposed surfaces laterally toward one another to grip the shaft therebetween while remaining generally parallel.

  • Patent number: 4935993
    Abstract: A jam cleat for holding a rope under tension is disclosed. The cleat comprises two converging surfaces between which a roller is located. The rope is inserted between the roller and first of the converging surfaces. When the rope comes under tension friction between the rope and the roller causes the roller to roll along the second converging surface and thereby grip the rope with a wedging action. Devices are disclosed for forcing the roller to release the rope. One such, device is a lever which is optionally pivotably mounted on the cleat. In one example the cleat comprises a base and a body embodying the converging surfaces and the roller and slidably mounted on the base. The body can be moved along the base by the rope as it comes under tension and the base is provided with an abutment which is brought to bear on the roller during this movement and forces the roller to release the rope.

  • Patent number: 4916850
    Abstract: A line attachment device for fixing objects to a line such as a fishing line, a string or a piece of rope. The device includes a shank or stem securable to the object to be fixed. The line attaching portion of the device includes a plug fixed to the stem, a cleat next to the plug and extended outward from it, and a cap with a central opening that fits snuggly over the plug. To fix the line to the device, an open loop is formed in the line and is trained through the opening in the cap when the cap is removed from the plug. The loop is drawn over the end of the plug and over the cleat such that it bears against the cleat when pulling toward the plug. The cap is then secured on the plug to hold the loop in place. The loop is secured on the cleat and is prevented by the cap from passing over the cleat whereby the line is secured to the line ataching device and thus to the object.
