Abstract: A ball screw with a dust-proof and lubricating device comprises: a screw, a nut, a plurality of balls, an oil-absorbing member, a return unit, and two dust-proof members. The nut includes an axial oil-guiding hole, a plurality of radial oil holes in communication with the oil-guiding hole and the helical groove of the nut, and an oil-feeding hole in communication with one of the radial oil holes. The oil-absorbing member is disposed in the oil-guiding hole and the radial oil holes. The return unit is disposed in the nut to enable the turning and circulation of the balls. The two dust-proof members are located at both ends of the axial hole. The ball screw can still be lubricated when it is disposed in a vertical position, and the dust-proof and lubricating device which won't add axial length to the nut.

Abstract: A shaft seal assembly for use with a reciprocating or rotating shaft includes a shaft seal, a lubricant-storing ring, and a retainer. The retainer and ring can be formed as a subassembly and then combined with a shaft seal. The assembly provides a lubricated shaft and seal that improves the effective life of the shaft seal.

Abstract: A method of and device for applying a liquid coating to the threads and only the bearing face of a threaded nut and the resulting coated nut are provided. The method includes providing a pumping mechanism that has a container containing the liquid lubricant and a pumping mechanism connected with the container. The pumping mechanism includes a liquid ejecting device having an actuatable delivery mechanism. A foraminous pad supports the face of a nut that is to have liquid lubricant applied thereto. A nut to be coated with the lubricant is placed on the foraminous pad and thereafter the delivery mechanism is actuated to eject liquid onto the threads and the foraminous pad to provide a nut which has coating on only the threads and on the bearing surface or face.

Abstract: A tire bead lubricating assembly for lubricating the bead area of a tire includes a lubricator sleeve mounted for reciprocal movement into and out of the center of the tire. The sleeve has an hourglass shape for engagement with the opposed bead of the tire when inserted into the center of the tire.

Abstract: A low displacement lubricator for use in the process of inserting fuel injectors into fuel injector manifold pods, the lubricator has a defined reservoir having an open cell foam disposed therein and an applicator in fluid communication with the reservoir. The applicator having an open cell foam that provides capillary dispensing of the lubricant. The amount of lubricant applied is in effect metered.

Abstract: An internal mandrel assembly is provided that includes a cleaning attachment for cleaning the interior surface of a tube during a bending operation. The internal mandrel assembly includes a mandrel shank, a plurality of mandrel ball assemblies pivotally coupled to the mandrel shank in a linked configuration, a cleaning attachment pivotally coupled to the last mandrel ball assembly, and a locating rod that positions the mandrel shank within the tube. The internal mandrel assembly also cooperates with a lubricant pump and a lubricant collector. The cleaning attachment includes a wiper for cleaning the interior surface of the tube, a linking member, a first support washer, a second support washer, and a retaining shoulder.

Abstract: A new method and apparatus for quickening in the insertion of a fish tape through a conduit by reducing the occurrence of frictional adhering. The apparatus provided in several embodiments uses flexible lubricant carrying materials having pressure sensitive fluid release characteristics affixed to the free end of a fish tape. The apparatus is saturated with a fluid lubricant prior to being inserted into an opening of the conduit and pushed. As the pressure sensitive material enters a bend in the conduit, pressure is applied to the pressure sensitive material by the long radius wall surface of the bend causing lubricant to be released. The possibility of frictional adhering of anything being pushed through the bend is greatly reduced. The apparatus moves past the well lubricated area and is immediately followed by the body of the fish tape.

Abstract: A die used in a reloading press for reloading spent cartridges. The wall of the die is provided with a reservoir for liquid lubricant. A lubricating pad is provided inside the die mouth and lubricant from the reservoir is channeled to the pad. A primary reloading die feature is provided for the die, e.g. a primer removing rod, and as a cartridge is forced into the die for removal of the primer, it is additionally lubricated ready for resizing.

Abstract: An improved lubrication system for lubricating the moving parts of a walking beam compressor used in compressing low pressure natural gas. The compressor is mounted on a walking beam oil pump. The lubrication system introduces oil through the length of a piston shaft and through a plurality of oil cooling chambers in the interior of a piston. The oil is then forced out through piston outlet ports disposed between the piston's compression rings and wear rings for providing an improved lubricant seal and extending the life of rings.

Abstract: A load-carrying, shock absorbing strut is provided comprising an outer tube for carrying a wheel axle journal. There is slidably accommodated in the tube a shock absorber cylinder which is connected with the chassis frame. A downwardly emerging piston rod of the cylinder is fastened to the bottom of the outer tube. Between the shock absorber cylinder and the outer tube there is provided a lubricant annular chamber of constant volume which is closed off above and below by upper and lower guide and sealing rings arranged on the outer tube. A sealing ring is arranged above each guide ring with axially limited play and comprise lubricant-sealing felt rings. To effect good dirt-deflecting action there is present above the upper sealing ring a dirt-deflecting ring which has the dual function of limiting the sealing ring axial play as well as removing dirt from the shock absorber cylinder.

Abstract: A method and apparatus for dispensing a fluid in a conduit and more particularly for dispensing lubricant within an electrical conduit for facilitating pulling electrical cables through the conduit. The apparatus is in the form of a cartridge disposed in the conduit at an end thereof. The cartridge is made of a pair of sealed and separable members. One of the members is a flanged sleeve forming the casing of the cartridge, in which is coaxially disposed the other member forming a tubular support member or carrier for a mass of resilient and absorbent lubricant impregnated porous material compressibly packed between the inner surface of the sleeve casing and the carrier. A cable pulling strand, or fishtape, is passed through the tubular carrier, and the cables to be pulled through the conduit are attached to the end of the fishtape. A plug inserted in the open end of the tubular carrier prevents the fishtape and the cables attached thereto from being pulled back through the carrier.
