Patent number: 5316421Abstract: A wheel chock for restraining a motor vehicle in a transportable carrier such as a railway car, which is adapted to be selectively connected to a rail fastened to the floor of the carrier and which is made of a flexible copolymer material capable of withstanding the loads incurred by chock restrained vehicles, and further which is user friendly in that it can be maintained in a wheel-restraining position together with a wheel harness and removed from that position without the use of any tools. The wheel chock includes a torque tube for winding up a wheel harness strap to tighten the wheel harness on a vehicle wheel, a strap take-up device for quickly removing the slack in the strap, and a foot-operated actuating lever for rotating the torque tube and operating a pawl and ratchet mechanism controlling rotation of the torque tube.Type: GrantFiled: October 29, 1992Date of Patent: May 31, 1994Assignee: Standard Car Truck CompanyInventors: Robert L.

Patent number: 5176083Abstract: A friction casting for use in a railroad car truck between a side frame column and a bolster pocket slanted wall has a slanted wall to face and be in contact with the bolster pocket slanted wall and a vertical face in contact with the side frame column. The friction casting has a hollow interior, except for a support rib which is perpendicular to the slanted wall of the casting and supports the slanted wall of the casting generally at the zone of contact with the bolster pocket slanted wall. The support rib transfers the load from the slanted face of the friction casting to the vertical face of the friction casting generally at the center of pressure thereof.Type: GrantFiled: April 23, 1991Date of Patent: January 5, 1993Assignee: Standard Car Truck CompanyInventor: Robert L.

Patent number: 5011347Abstract: A wheel restraining cleat and strap for use with a pair of wheel chocks to anchor a vehicle wheel to a supporting surface such as a floor of a railway car for transporting vehicles, which includes a strap of flexible material for overlying the tire of the vehicle wheel and carrying thereon a cleat formed of a material having both flexibility and resiliency so that it grabs the tire to retain the strap in overlying relation with the wheel. The cleat includes protuberances on the tire-engaging side to prevent slippage between the tire and the cleat, thereby maintaining the strap in overlying tie-down relation to the wheel. The cleat is sufficiently bendable to conform to surfaces of tires of different diameters.Type: GrantFiled: November 29, 1989Date of Patent: April 30, 1991Assignee: Standard Car Truck CompanyInventor: Robert L. Bullock

Patent number: 4537138Abstract: A railroad truck includes a pair of side frames with wheeled axles mounted there between. A roller bearing adaptor is mounted upon a roller bearing at each end of each axle with the side frames being mounted upon a shear pad mounted on the roller bearing adaptors. There is a subframe for interconnecting the wheeled axles by connecting opposite corner adaptors and there is a rigid connection between each adaptor and the subframe. Each rigid connection includes an adaptor portion and a subframe portion, with said portions being relatively vertically disposed. There are vertical fastening means connecting said vertically disposed adaptor and subframe portions. The vertically disposed portions have cooperating means thereon which substantially eliminate horizontal shear forces upon the fastening means.Type: GrantFiled: July 5, 1983Date of Patent: August 27, 1985Assignee: Standard Car Truck CompanyInventor: Robert L. Bullock

Patent number: 4359288Abstract: A ribbon cartridge is provided to be used in a high speed impact printer having means for driving only one reel in the ribbon cartridge, the take-up reel. The ribbon cartridge comprises a cartridge housing having an open end, and supply and take-up reels rotatably mounted in said housing. The supply reel supports an inventory of unused ribbon web which runs from the supply reel to the take-up reel. The rib is mounted in the cartridge housing facing the open end in a position closer to the supply reel than to the take-up reel.The printer into which the ribbon cartridge is to be inserted contains driving means for driving only the take-up reel. The printer receiving means into which the cartridge is to be inserted includes a stop element disposed so as to block the rib to stop the engagement of the cartridge and the receiving means when the cartridge is being inserted in a direction towards the undesirable engagement of the drive means with the supply reel rather than with the take-up reel.Type: GrantFiled: June 16, 1980Date of Patent: November 16, 1982Assignee: International Business Machines CorporationInventors: Robert L. Bullock, Billy D. Purcell, William J. Thornhill, Edward E. Toutant

Patent number: 4276833Abstract: A friction member for use in the bolster pocket of a stabilized railroad car truck having a bolster positioned within a side frame window has a slanted friction surface adapted to bear against a slanted wear surface within the bolster pocket and a vertical friction surface adapted to bear against a side frame wear surface. The slanted friction surface has a profile in a generally horizontal plane consisting of a central flat portion and adjoining outside arcuate portions. The flat portion has a width equal to twice the distance between the side frame center line and the point of rotation of the side frame relative to the bolster, with said point of rotation being selected such that, during side frame rotation, the distance from the side frame center line to the point of intersection of the plane of the vertical friction surface and the plane of the side frame wear surface is no greater than one half of said friction member horizontal thickness.Type: GrantFiled: November 8, 1978Date of Patent: July 7, 1981Assignee: Standard Car Truck CompanyInventor: Robert L. Bullock

Patent number: 4196672Abstract: A railroad car truck bolster has a centrally disposed vertically arranged longitudinally extending web. The web has spaced reinforcing means with the spacing of the reinforcing means being sufficient to cause certain fractures in the web propagating along lines of maximum shear stress at approximately 45 degrees to lines of principal stress to reach a reinforcing means at a point closer to the neutral axis of the web than the next adjacent external surface of the web. The bolster side walls have openings with the above-described spaced web reinforcing means being generally in alignment with the bolster side wall openings.Type: GrantFiled: June 19, 1978Date of Patent: April 8, 1980Assignee: Standard Car Truck CompanyInventor: Robert L.
