Abstract: A bearing support member, mountable about a support stud, has two support arms extending toward side walls of a rocker arm. A bearing cup is rigidly mounted on each respective side wall and extends over the respective arm of the bearing support member, providing an annulus. Rolling members within the annulus permit the rocker arm to freely oscillate rotatably while being constrained axially. The bearing cups may include a keyed shape to limit orientation of the bearing support member. Another aspect of the invention is a rocker arm subassembly having "open" bearing cups.

Abstract: A plastic knuckle pin for a coupler on a railway car which accepts bending fatigue, eliminates rust or corrosion, and reduces the coefficient of friction during opening and closing the coupler. The pin also protects the integrity of the coupler body and the knuckle to reduce coupler maintenance and further reduces the weight of the railway car and facilitates the use of a self-locking feature.

Abstract: A bearing support member and bearings form a subassembly that can be inserted, in the direction of the axis of the bearings, into a bore of a rocker arm. A support stud can then be passed through an aperture in the rocker arm and a bore in the bearing support member so as to engage the rocker arm and maintain alignment of the rocker arm and bearings. Also disclosed are an inner sleeve and particular configuration of the bearing support member to facilitate manufacture of the bearing support member by powdered metal forming.

Abstract: A bearing apparatus includes a race, the race being tubular and having first and second axial ends. One of the axial ends having a restrainer. A separator having first and second annular rims is interconnected by separator bars being annularly spaced apart. A plurality of rolling elements are retained by the separator bars and rims. A flexure member permits the separator to be radially flexed in a first radial direction for axial displacement with respect to the race and to be radially flexed in a second radial direction, opposite said first radial direction, for being restrained with respect to the race. The race may be an inner race or an outer race. A second race interrelates with the separator to lock the separator in the second radial direction. The restrainer is preferably an annular groove formed in the race.

Abstract: The bearing assembly when pressed on a shaft will be axially located in either direction. The assembly consists of a roller bearing assembly which is pressed into an outer sleeve while entrapping an inner sleeve serving as an inner race. The inner race is pressed onto a shaft and has a turned up flange which serves as a thrust surface on both sides.

Abstract: A brake rod protector for a brake rod in a braking system of a railway vehicle to repair a worn brake rod or to provide protection against wear along an area where wear normally occurs. The protector includes a metal base plate shaped to conform with the brake rod and be attached thereto by welding or the like and a body of plastic material bonded to the outer surface of the base plate and to be slidably engageable with a member of the braking system or the railway vehicle.

Abstract: The bearing is used on a mechanical machine part or apparatus part which allows linear movement of the part along a second machine part or apparatus part and also allows angularity of one part with respect to the second part. A generally rectangular roller block is provided with raceways around its entire periphery. Rollers fill all of the raceways. Two opposite raceways have their rollers enclosed; the other opposite raceways have rollers which are in exposed operating positions so that they may contact the second machine. The rollers are retained within the roller block by one or more roller retaining members.

The coupler shank lower wall is formed with an elongate mounting slot at the location of application of the conventional wear plate, and extending longitudinally of the coupler shank, to which slot is applied a one piece bearing structure formed from an ultra high molecular weight polymer of dry self lubricating characteristics.

Abstract: A self lubricating liner for railroad car center plate assemblies comprising a bowl shaped member formed from an ultra high molecular weight polymer of dry self lubricating characteristics and shaped to define a floor portion and an upstanding side wall. The liner is stretch resistant and is received within the trunk bolster bowl on the floor of the bowl, it being proportioned to be fit on the bolster center plate and to entirely fill the space between the truck bolster bowl and the body bolster center plate 360.degree. about the side wall of the bowl to preclude high energy impacts between these parts when coupler impacts and train line action are occasioned. The liner side wall is formed to be spaced from the top surfacing of the bowl side wall and make a tight seal about the neck of the bolster center plate. In use, the liner effects resurfacing action on the surfaces engaging same to make them effectively resistant against wear.
