Abstract: The storage of pipes hoisted by means of a wire-rope sling tightly noosed around the pipes to form a pipe bundle is facilitated by clamping the rope in the sleeve of the sling choker to lock the tight noose against loosening when the pipe bundle is deposited on a support and is connected from the hoisting means. The sleeve bore is of generally keyhole section. The rope is a sliding fit in the part-cylindrical portion of the bore so as to be locked in said portion and project laterally into the adjacent channel portion of the bore. By force-fitting a pin into the channel portion in which the pin is a sliding fit, the rope length in the bore is clamped against the part-cylindrical portion of the bore.

Abstract: Mounted adjacent the end of a plastic hose remote from its connection to a kitchen sink faucet or other such water source is an improved hose-pinching clamp assembly of the present invention which enables effective watering of remotely located plants. The significant improvement in performance is that the clamp, during normal watering service, is confined to providing a desirable "soft" stream by a pliable sleeve or tube in covering relation over the clamp, said tube maintaining the clamp partially closed upon the hose so as to restrict flow to said "soft" stream. Prior art clamps, in contrast, can inadvertently be opened too much, and may therefore operate with a watering stream that splashes or otherwise is unsuitable for the purposes intended.

Abstract: A device for docking and mooring a boat including an elongate member having a series of convolutions formed therein to provide a continuous convoluted surface. When a throwline having an enlarged end portion is engaged with the convoluted surface, contact will be maintained therebetween so long as tension is maintained no matter what directional changes are made between the line and the surface. Several embodiments are disclosed ranging from catching devices alone to such devices which may be released from a remote location.

Abstract: A chock for mountain climbers is in the form of a truncated pyramid having sides of unequal width so that the chock is readily conformable for secure wedging engagement virtually in any type of crevice, the chock being manufactured in different sizes according to variations in size of cracks or crevices encountered in mountain climbing. The configuration permits central placement of one end of a carabiner, the opposite free end of which is provided with a hero loop to permit fastening of a ring for direct connection of the climbing rope thereby obviating connection of an additional carabiner.

Abstract: The clamp, operable to compressively lock a wire, comprises a casing having a cone-shaped cavity therethrough, and means engaging the cavity about the wire, the means gripping the wire as a result of constriction of the cone-shaped cavity as a result of loads applied to the wire.

Abstract: A cable gripping device which is readily adjustable and fail-safe. The device includes cylindrical inner and outer housings in telescoped relationship which contain an inner gripper member and an outer compression spring connected to the housings. When the housings are biased apart by the compression spring, the gripper member is forced into tight contact with a rope or cable passing axially through the housings, locking the assembly in position on the cable. If the housings are moved toward each other, the compression spring is compressed and the gripper member is loosened, allowing the assembly to be moved along the cable. If the operator releases the housings, such as by slipping and falling, the compression spring automatically moves the housings apart, causing the gripper to again grip the cable. This device is especially suitable for use by workers in high locations, since they can move about along a safety cable without unhooking their safety lanyards from the cable.

Abstract: A choker assembly for logging winchlines. The assembly includes a choker rope with a ferrule at one end. A choker hook is slidably mounted to the rope for releasably receiving the choker rope ferrule. The remaining end of the choker rope is releasably attached to a winchline slider. The slider includes an integral enlarged winchline opening and an angular offset choker rope opening. The choker rope opening is tapered, with a reduced outer end and an enlarged inner end for receiving the free choker rope end. A conical sleeve is releasably mounted to the free end of the choker rope so as to expand the rope end to a cross-sectional diameter greater than the diameter of the choker rope opening. Thus the choker rope end is held against outward movement through the choker rope opening. The rope may be selectively removed simply by removing the conical sleeve from the choker rope end. This allows the rope to return to its original diameter and be pulled through the choker rope opening.

Abstract: A metal housing for a splice case including a channel member and a plate which extends between the parallel sidewalls of the channel member. The channel member and associated plate thus form a first cavity, open at either end, in which a resilient splice case may be positioned. A passageway is also defined on the other side of the plate and between the outer portions of the parallel sidewalls. Flanges associated with the plate extend out of the channel member such that when the housing is securely positioned on a large pipe or the like, channel side down, the plate will be forced deeper into the channel member to further compress a splice case located therein. The rigid housing acts to protect the splice case and hold it in position.
