Abstract: A load cell includes a bearing element configured for a hoist that includes a hook, a suspension with an orifice that receives a shaft of the hook, a nut, and housing. The bearing element, preferably a ring, contacts the suspension, and has an orifice that receives the shaft therethrough with the nut secured to the shaft proximate to the bearing element. Strain gauges are mounted on the ring side wall being equally spaced. A second suspension orifice concentric with the first orifice receives the ring with strain gauges therein. For improved accuracy, a thrust roller bearing and two thrust washers are positioned on sides of the ring, all of which are preferably positioned in a cup member that is received in the second orifice. A clearance fit is provided with respect to each of protruding upper and lower overhanging cylindrical ring lips and the cup to protect the gauges.

Abstract: A load securing pulley supports the weight of a hoisted load by restraining a load-support cord in order to maintain tension within the load-support cord between the hoisted load and the load securing pulley. The load securing pulley includes a wheel-supporting housing, a wheel-receiving opening, a hook retention eye, a rope lock, and a pulley wheel. The hook retention eye is connected to the wheel-supporting housing such that the present invention is able to be suspended from a hook to a raised horizontal support. The wheel-receiving opening laterally traverses into the wheel-supporting housing in order to allow the pulley wheel to be positioned and rotate within the wheel-supporting housing. The rope lock allows for the load-support cord to be secured to the present invention through tension due to the weight of the hoisted load.

Abstract: A pulley block has a body which rotatably supports a sheave, the block having a mounting pin which extends through a bore in the block. The pin has an enlarged head disposed internally of the body to retain the pin in the bore. Rotation of the pin may be prevented by a releasable locking arrangement comprising a groove formed transversely across the enlarged head of the pin and a lock member rotatably mounted in a hole extending within the block adjacent the head of the pin. The lock member is profiled for rotation between a locked position where a part of the lock member locates in the groove in the head of the pin to restrain rotation of the pin and a free position where the lock member is free of the head of the pin so that the pin may rotate.

Abstract: A line-handling block particularly for sailing vessels has an attachment device (30) rotatably mounted in the body. Locking device (50) are slidable in keyhole slots (60) into or out of engagement with the attachment device (30). When in engagement the locking device (50) may permit only limited rotation of the attachment device to either side of a central position. They may yield if an excessive torsional load is experienced, and may be supplied in various interchangeable forms for fitting to a given block so that its characteristics may be adjusted.

Abstract: A retractable leash for two animals which includes two spool assemblies (24A and 24B) for individual extension and retraction of each animal's cord. Each animal's cord is controlled by a button and locking mechanism. The cord holes (20A and 20B) where the leash cords (12A and 12B) exit are opposite of each other to minimize or prevent entanglement. If the leash cords cross, the operator need only rotate the lease handgrip (38) to uncross the cords. In one locking design, braking and locking buttons (18A, 18B, 18C, 18D and 16A, 16B, 16C, 16D) are placed on both the top and bottom of the leash handgrip (38) so that the operator may turn the leash and be immediately ready to control the forward movement of the animals. The leash may also be adapted to mount on the animal's collars as separate units which fasten together to form one walking leash.

Abstract: An improved dog leash for use with two or more dogs that enables two dogs to be walked simultaneously. The invention resists tangling and is designed to minimize the effect each dog has on each other in the natural course of the inventions use. Moreover, the invention takes into account the natural predilections of dogs in that the leash allows the dogs to roam more freely. However, the invention also accounts for the differences in the strength, size and activity of each dog attached to the invention by minimizing the effect each dog has on the other.

A manually operated latch mechanism is mounted in the head, and the latch may be moved into engagement with one or more recesses in the post to lock the post in a given position.

Abstract: An apparatus for guiding elongated items, such as cables, wires, hoses, and the like, onto or from spools. The apparatus includes two frame members that are pivotally and hand-releasably connected together to form an enclosed frame through which the elongated items are guided. A first pivotal and hand releasable connection is made between a first leg of the first frame member and a first leg of the second frame member. A second pivotal and hand-releasable connection is made between second legs of the frame members to provide a releasable opening of the enclosed frame. The releasable opening provides access to the enclosed frame for installation of the elongated item without requiring access to one of the ends of the elongated item to thread it through the enclosed frame. One of the frame members also includes provision for attachment to a mount, by which the enclosed frame is held in any of a plurality of selectable positions with respect to the mount.

Abstract: A U-shaped suspension ring is pivotally supported on a horizontal pin inserted through a suspension shaft supported by the top plate of a load suspending tripod or by a support member disposed at a high place. In order to lift a chain block to the position of the suspension ring, a rope passed around the hook of the chain block is divided into a hook lifting rope portion extending around the opposite ends of the horizontal pin and tension rope portions to be pulled from the ground.

Abstract: A snap roller utilized as a snatch lock employs a pulley and a rod fabricated from a wire-like spring material to which the pulley is journalled. The rod has a portion of its length, located substantially in the central regions thereof to which the pulley is journalled. A pair of portions of the length of the wire-like rod extends radially outwardly from the longitudinal axis of the pulley in a direction substantially parallel to one another. The ends of the wire-like rod are formed into oppositely directed hooks such that each of the distal ends approach, and if desired contact the opposed length of the pair of portions of the wire-like rod. In use, a rope or line may be passed between the hook-like ends so so as to engage a groove in the pulley due to the fact that each hook-like end resides in planes that are skew to one another allowing the distal ends of the hooks to be forced outwardly from the opposed one of the pair of portions of the wire-like rod.
