Abstract: A system for lubricating a wire rope includes a housing configured to be mounted adjacent a wire to be lubricated. A cartridge for housing lubricant is disposed on the housing. At least two nozzles are in fluid communication with the cartridge and configured to dispense the lubricant onto a respective wire at a position adjacent a weight bearing portion of the wire.

Abstract: A strap may be removably attachable to a container. The strap may include a retractor having an opening, a retraction spring and a brake. The strap may further include a strip of flexible material attached to the retraction spring and extending through the opening of the retractor. The strap may also include clips attaching the retractor and distal end of the flexible material to the container. The strip of flexible material may move from a fully retracted position, where the distal end of the strip of flexible material is nearest the retractor, relative to the entire length of the strip of flexible material, to an extended position where the distal end of the strip of flexible material is furthest from the retractor. The retraction spring may bias the strip of flexible material into/toward the fully retracted position.

Abstract: A pulley comprises: a monobloc sheave comprising two opposing longitudinal faces, a transverse central recess and a concave external surface forming an annular groove which is provided in order to redirect a rope, the central recess and the concave external surface being fixed relative to each other, a fixing rope of the sheave, which extends through the central recess of the sheave, the fixing rope being in direct contact with the central recess, a spacer element which is arranged in order to space the fixing rope away from the longitudinal faces of the sheave.

Abstract: A swivel mount for solar tracker shafts having a clamp having an inner surface with a spherical shape and first and second parts forming a brace adapted to hold a solar tracker shaft, wherein the brace formed by the first and second parts has an external surface having a spherical shape, such that the solar tracker shaft is axially retained by the clamp and can be oriented in any required spatial position.

Abstract: A surgical cutting instrument comprises an outer tubular member having a proximal section, an intermediate section and a central lumen. An inner tubular member is rotatably received within the central lumen and includes a distal end forming a cutting member extending distally beyond, and exposed relative to, the distal section of the outer tubular member. A bearing assembly is coupled to the outer tubular member and the inner tubular member.

Abstract: A pulley seat includes a housing including a cover including a slot on an intermediate portion, and a casing including first and second stepped diameter holes on both sides respectively wherein the housing is integrally formed by hot forging; a pulley including an axial channel; a bearing having an axial hole and being rotatably disposed in the axial channel; a stepped-diameter first sleeve disposed in the first stepped diameter hole; a stepped-diameter second sleeve disposed in the second stepped diameter hole; and a pivot pin rotatably disposed in the first sleeve, the axial hole, and the second sleeve.

Abstract: A wireline hay pulley has a support with front and back plates extending therefrom. A sheave disposed between the plates can rotate on an axle. The front plate is affixed to the support, while the back plate is removably connected to the support. The front plate has a round opening in which an eccentric bushing on the axle can rotate. When the back plate is disconnected from the support, the back plate can turn the axle fixed in a slotted opening. An eccentric bushing on the axle rotates in an opening of the front plate, thereby shifting the sheave away from the support. With the back plate moved away and the sheave shifted downward, an operator can readily rig up a wireline in the sheave's slot.

Abstract: A block with a rotating sheave mounted between a pair of side plates. Between the side plates may be a post about which a mounting loop may be mounted. The post is configured to permit the loop to be attached or detached from the block.

Abstract: A system and method for tensioning a cable. A thimble is placed over an eccentric member having a splined bore. A portion of an endless cable is placed over the thimble. The eccentric member and thimble are placed between a pair of parallel, spaced apart arms of a mounting structure. A splined shaft is inserted through holes in the arms and into the splined bore of the eccentric member to secure the eccentric member to the mounting structure. A threaded nut is placed on a threaded end of the splined shaft. The cable is tensioned by rotating a head portion of the splined shaft 180 degrees, or by a different predetermined value, which places the cable under a predetermined tension. A retaining screw is inserted through one of the mounting structure arms and into a threaded hole in the eccentric member. The system enables a precise degree of tension to be quickly and easily applied to a cable with no risk of accidentally over-tensioning the cable.

Abstract: The present invention is a sheave assembly that includes a ring supported by a support assembly instead of a solid sheave wheel supported by a central axle. The support assembly may include a plurality of rollers or a curved shoe. The ring is made of a lubricated plastic material or other similar material. The ring includes a groove for retaining the wireline or cable and an inner surface that is designed to mate with the outer surface support assembly.

Abstract: A bearing block has a head, a central hub, bearing means facilitating rotation of the sheave about the central hub. The block further has locking means for removably locking a length of high strength, fibrous material, such as cord, to the block for tethering the block to a boat deck or the like. The locking means may be a part of the block head, cheeks, or may be located at the block central hub. Preferred locking means are a plurality of passages for the cord ends to pass through, with set screws in two of the passages for removably holding the cord ends therein. A center portion of the cord length thus forms a loop for tethering the block.

Abstract: The outer race of a roller bearing sheave is omitted so that the bearings are in direct engagement with a line. A retainer for the ends of the bearings is provided to allow the bearings to rotate and recirculate around an inner race. The rollers deflect portions of the line equally to equalize the load and to prevent high stresses on individual rollers.

Abstract: A marine block employs a sheave which is rotatively mounted on an axle supported between a pair of spaced-apart cheek plates. One or more ball bearing units are provided between the axle and the sheave, each unit containing a circular array of ball bearings which engage in circular races which are disposed radially outward from the axis of the axle. Relatively large ports are formed in the cheek plates which are located directly opposite the bearing units whereby a water stream directed through the ports at one side of the block can penetrate around and between the exposed ball bearings and their races and scrub those surfaces free of dirt and film. In a preferred block embodiment, clearance spaces exist radially inboard of the sheave between the bearing units and between the sheave and the cheek plates so that water can travel directly through the block and between the sheave and the cheek plates to further facilitate cleaning the block.
