Abstract: A linear bearing is made with races molded in place in a plastic shell. An inner ball cage is assembled by sliding the cage into the shell. Open ends of the ball receiving guides in the cage slide along the inward extending races. The cage and ball guide are completed with a cap fitted in an opposite end of the shell.

Abstract: To replace conventional ball-cage strips for remote controls in which push-pull blades slide on ball bearings maintained properly spaced from one another by such strips, a linkable ball-cage element has been developed to form strips of such linked elements that overcome limitations of prior ball-cage strips. Each element has a head and neck at one end and a cavity and narrow entrance at the opposite end so that the head of one element can be inserted into the cavity of another element. Each element holding a ball is thus linked with other elements to provide a very flexible strip of any desired length.

Abstract: A bearing has a self-lubricating liner including sheets of felted polytetrafluoroethylene fibers impregnated with cured phenolic resin having no surface bonding to the fibers. Sheets of fibrous fabric are felted to sheets of felted fibers. Sintered particles are dispersed in the low friction surface of the liner. Liners are formed by air drying resin-impregnated sheets of felted fibrous material. The resin may be cured in a heated platen press before assembly of the bearing. The bearing is assembled by deforming bearing members to form an interference fit between the members and a bearing liner disposed therebetween. Parting compound applied to one of the bearing members prevents bonding of the liner to that member when the liner is baked to cure the resin and bond the liner to the other member.Bushes and bushings having self-lubricating linings are disclosed. Arbors and mandrels form an interference fit between the linings and bushes and bushings during assembly.

Abstract: Bicycle Chain is made of alternating bushing links and pin links. The bushing links have parallel bushings held in interference fit in bushing plates and extended axially beyond the bushing plates, solid metal rolls with a lubricating plating are held loosely on the bushings, and loosely between the bushing plates. The bushings extend axially outward beyond the bushing plates for substantial distances. Pins extend through the bushings and are fixed in pin plates to form pin links which alternate with the bushing links. The pin plates are held outward from the bushing plates for a substantial amount by the axial bushing extensions to prevent dirt build up. The pin plates, bushing plates and bushings are plated with an anti-corrosion plating. The pins and rolls are plated with a porous metal plating with solid polymeric lubricant held within pores of the plating for lubricating the pin-bushing interior interface and for lubricating the roll-bushing and roll-bushing plate interfaces.

Abstract: Balls are loaded into ball recirculating grooves of linear bearings by snapping balls past resiliently deformable edges of slots in the linear bearings. The edges are lips on ball exposing slots adjacent races in linear bearings.

Abstract: In each end fitting of a flexible remote control, improved anchoring of the outer ball races is achieved by attaching the end of one race to a fixed anchor which is at least partially cylindrical so that it can rotate in the fitting and by attaching the end of the other race to a slidable anchor which is in sliding contact with the race attached to the fixed anchor. The push-pull blade of the control passes through a slot in each of both anchors which help prevent bowing of the blade when subjected to a heavy push load.

Abstract: A chain assembly for easy removal and replacement of a module for supporting and carrying objects along a path parallel to chain movement. The chain has a pin link with a hollow pin adjacent an extended pin. A module having cylindrical shaft and perpendicular plate is inserted into the hollow pin so that a hole in the plate fits over the extended pin. The module is secured to the chain by insertion of a cotter pin into a hole at the end of the extended pin.

Abstract: A push-pull cable assembly for use in high temperature environments, particularly for use with engines generating high temperatures in application, has a cable conduit with a natural nylon outer tubular element and a nylon inner tubular element helically wrapped by wires. Nylon 66 is preferred. A chromatic indicator is included in the outer element. Exposure to the elevated temperature environment for a long period of time causes the conduit to change from its original green color to dark brown as failure of the assembly becomes imminent. The cable assembly is replaced when the conduit turns dark tan or brown.

Abstract: A cold header or a screw machine preforms a rod end blank from rod stock. A female blank has a drilled and tapped rod portion and an undersized spherical head portion. A male blank has an unthreaded straight shank and an undersized spherical head portion. The rod portion is necked adjacent the head portion. The blank is placed on an indexing table which advances the blank through a series of processing stations. The head portion is heated for three seconds with an induction coil, rested for one second, and heated again for three seconds with an induction coil. The head portion is then flattened, shaped and enlarged in a closed die press. The head portion is quenched to room temperature. The head portion is punched in a die punch to remove the slug and flash.

Abstract: Dissimilar pairs of identical parallel longitudinal grooves having enlarged U-shape central pockets open outwardly along opposite faces of a support block for pivotally receiving correspondingly dissimilar end fittings of cable conduits. A U-shape retainer detachably connects to the block to hold the end fittings in the grooves. The block is connected to a mounting plate in any one of a plurality of positions. In use, the block is turned to match corresponding grooves and end fittings and is connected to the plate to support the cable in a desired position.

Abstract: Apparatus is provided for adapting the clamp-type end fitting of a push-pull cable assembly to a bulkhead-type fitting. Identical semi-cylindrical castings form a sleeve on the cable assembly. The castings are offset axially with respect to each other. Ridges formed on the inner surfaces of the castings cooperate to engage an annular groove formed in the cable assembly and thereby hold the sleeve on the cable assembly. Two nuts threaded onto the outer surface of the sleeve mount the assembly to a wall or bulkhead.

Abstract: A filter element has a filter medium positioned between concentrically spaced cylindrical walls. A semiflexible, urethane ledge gasket has an annular seal portion that sealingly engages one end of the walls and filter medium and an edge of a generally circular retainer plate that closes one end of the filter element. An annular gripper surface extends inwardly from the seal portion and is spaced axially from the outer surface of the retainer plate so as to provide a finger gripping surface so that the filter element can be removed from its housing. An annular lip extends outwardly from the seal portion to engage an end of the housing.

Abstract: A chain breaker has an interchangeable turret anvil plate mounted on an upper surface of a lower jaw. The lower jaw has a slotted upper portion which extends partially over the anvil plate. An upper jaw has a reduced lower portion which fits within the slotted upper portion of the lower jaw. A retainer pin extends through the slotted portion and holds the jaws together. Near the pin a retaining portion of the upper jaw extends over the anvil plate and the threaded retainer and prevents accidental dislodgement of the anvil plate and threaded retainer. An outer surface of the retaining portion abuts a chain workpiece. A pin connects two handles on a line with the jaw pivot pin, and pins connect individual handles and the jaws on a line which intersects the first line close to the handle pin. A forcer screw in an outer end of the upper jaw carries a breaker tip at its lower end which is positioned just above a cantilevered portion of the anvil plate.
