Patent number: 5586669Abstract: A railcar cushioning device for absorbing impact between railcars is provided having a hydraulic cylinder containing hydraulic fluid. A piston locates within the cylinder and is movable relative to the cylinder between an extended position and a contracted position in response to draft and buff forces. First and second sensors are provided with the piston and cylinder for detecting movement of the piston and cylinder substantially between the contracted and extended positions. By means of a suitable logic circuit or microprocessor, the period of time that it takes for the piston and cylinder to move between the contracted and extended positions can be monitored to determine if the period of time is less than a preselected amount thus indicating that the cushioning unit has failed. A counter may also be provided to count the number of times that the cushioning unit has failed.Type: GrantFiled: May 3, 1995Date of Patent: December 24, 1996Assignee: FM Industries, Inc.Inventors: O. Elwyn Seay, Stephen K. Nickles, John E. Haley

Patent number: 5511486Abstract: The trailing, load supporting component of a product conveyor is connected to a powered, leading component by a shock absorbing tow bar that employs a dampener tube in which a plunger moves against the resistance of a sleeve of resilient material. The head of the plunger is oversized with respect to a passageway defined by the sleeve and thus is forced to compress and displace the resilient material in order to move relative to the passageway in response to an impact caused by rapid acceleration or deceleration of the conveyor. Compression and displacement of the material occurs at a zone of contact of the head with the material, the head shifting the zone of contact and compressing and displacing the material in response to the impact communicated to the tow bar. A protective sleeve shields an exposed plunger rod from contaminants and enhances the structural integrity of the assembly.Type: GrantFiled: September 16, 1994Date of Patent: April 30, 1996Assignee: LICO, Inc.Inventors: Mark A. Pollard, Wendy L. Calvert

Patent number: 4838173Abstract: An improved strain sensor is disclosed utilizing a linear variable displacement transducer (LVDT) to precisely output the linear strain over a structural member. The LVDT is mounted utilizing a position apparatus having a similar coefficient of thermal expansion as the structural member, and effectively integrates the strain over the entire longitudinal dimension of the member by precisely measuring displacement under load. This assembly is readily incorporated in locomotive couplers and crane structures having a void or hollow coinciding with the neutral bending axis of the member being tested, as well as over relatively large spans, in pairs or singly, having bending moments present. A locomotive control system for increasing the strain on a locomotive coupler by monitoring the draw bar force with an associated generator speed and maximizing the draw bar force by manipulating the generator speed.Type: GrantFiled: March 15, 1988Date of Patent: June 13, 1989Assignee: Rockwell International CorporationInventors: Paul K. Schroeder, Gary W. Sampson

Patent number: 4794867Abstract: The invention relates to an omnibus which is suitable for train formation, can be driven independently and can either be freely steered or guided on tracks. In order not to disfigure the omnibus front by protruding coupling devices, and to be able to carry out the coupling operation without an assistant from the driver's position of the particular omnibus to be coupled, it is envisaged that at least the front coupling is designed in the form of a bar which can be extended or retracted under remote control. In the extended state, the bar can be moved under control within limits and can be engaged with the counter coupling head of the omnibus in front. The coupled omnibuses of a train are simultaneously and uniformly controlled from the driver's position of the first omnibus with regard to all their traction and braking functions.Type: GrantFiled: January 4, 1988Date of Patent: January 3, 1989Assignee: Daimler-Benz AktiengesellschaftInventor: Walter Titz

Patent number: 4586620Abstract: An alignment device for railroad car couplers including a central flexible portion with a pair of swivelable end portions connectable between couplers of adjacent cars. Each of the end portions includes a protruding stud adapted to engage an opening preformed in the knuckle body. The device end portions and their studs are inserted between misaligned adjacent couplers. One steady pull of the engine aligns the couplers so that two cars may then be quickly joined together without requiring the trainman to stand between the cars during the coupling operation.Type: GrantFiled: April 23, 1984Date of Patent: May 6, 1986Inventor: Russell J. Andrews
