    Abstract: The invention is a model railroad track scrubbing car with rollers set at a scrub angle of about 30° to scrubs the tops and sides of the track rails. The rollers freely rotate about fixed axels under the chassis of the weighted car. Each roller is preferably a conventional paint roller with an inner sleeve and an outer tubular roll made of an absorbent, compressible, resilient foam material. The active working surfaces of each roller compress against, frictionally engage and deform around the tops and sides of the rails. The scrub angle and rollers provide across-the-rail scrubbing action and possibly along-the-rail scrubbing action. The circumferential working areas of the rollers are wider than the width of their associated track rails. The scrub angle and height of the roller axels above the track rails are adjustable to set the amount of roller compression and scrubbing action against the track rails.

The conveyor belt revolves around a pair of rollers mounted on the framework of a conveyor belt assembly. One roller magnetically picks up the metallic objects and a hydraulic motor powers the other roller to drive the conveyor belt. The magnetized roller is mounted via two mounting bearings which slidably engage the assembly. An adjustment bolt on the assembly engages the mounting bearing to move the magnetized roller to adjust conveyor belt tension to facilitate replacement of the belt. A lift beside the assembly raises and lowers one end of the assembly which rotates about a pivot tube within the conveyor belt. The lift, pivot tube and hydraulic lines connected to the motor are all situated to allow the belt to be removed without interference therefrom.

    Abstract: A lubricant applicator for disposing lubricant onto a metal surface. The lubricant applicator generally includes a combination holder and dispenser. Lubricant is disposed from the same portion of the combination holder and dispenser as the lubricant was inserted, in the rear portion of the combination holder and dispenser. A dispensing system applies constant force to the rear portion of the combination holder and dispenser so that lubricant is disposed from the rear portion and out of the front portion of the combination holder and dispenser. Lubricant, generally in the form of a stick, can therefore be easily replaced without removing the applicator from its location or without removing its mounting arrangement. Various applications and mounting arrangements for the lubricant applicator are disclosed, as is a method for providing a lubricant applicator.

  • Patent number: 6553693
    Abstract: A snowblower apparatus and a method of using the snowblower. The snowblower apparatus is self contained and portable and may be mounted on a prime mover. A turbine engine is located within a housing and discharges its exhaust to the desired area of snow or ice removal. The housing is rotatable and tiltable about orthogonal axes so as to allow the operator to direct the discharge nozzle to a desired location. A fuel tank may be mounted separately from the housing and turbine engine. An afterburner may be used to increase the exhaust temperature thereby to remove ice and otherwise dry the desired location.

  • Patent number: 6444046
    Abstract: A groove cleaning unit has a high pressure jet nozzle from which a cleaning liquid impinges in a high pressure jet stream inclined downwardly onto a cleaning surface and is covered by a covering screen. An exit opening for the dirt liquid mixture is placed in the cover screen. The cover screen (5) covers a piece of a railtrack (17) with a railtrack groove (3). A high pressure jet nozzle (1) is placed in the region of a front wall (8) on the jet stream side. A high pressure liquid jet stream (2) is directed onto an impingement location (4) in the railtrack groove (3) by the high pressure jet nozzle (1). A reflected liquid jet stream (11) of the high pressure liquid jet stream (2) is reflected under an angle. The angle is steeper as compared to the inclination of a lower screen wall (7) disposed inclined relative to a travel advance direction (19) and is rising forwardly. The reflected liquid jet stream (11) passes essentially immediately to an exit opening (18).

  • Patent number: 6349653
    Abstract: A maintenance cart in a maintenance system is substituted for a material handling cart in a continuous train of material handling carts circulating on a closed track. The maintenance cart includes both inspection and cleaning functions which may be divided among separate maintenance carts, as desired. Inspection includes location sensing (preferably with a bar-code reader), inspection with one or more television-like cameras and clearance measurements. Cleaning functions include removal of dust and debris from a channel-like track by a vacuum arrangement. The maintenance cart or carts may be continuously left in place or substitute as needed in the train and provide continuous cleaning service and system diagnostics for scheduling repairs prior to failure while in use. The system is particularly advantageous for application to mail sorting systems which are largely unaccessible and which permit only brief time windows during which maintenance, repair and inspection can otherwise be carried out.

  • Patent number: 6148732
    Abstract: A track cleaning system mounted on a railcar and comprising track rail cleaning nozzles, leaf removal nozzles and third rail cleaning nozzles. Each of the nozzles may provide a fan-shaped spray pattern diverging to either side of a central axis and having a major axis. For each track rail nozzle, the central axis may be perpendicular to a horizontal top rail surface and the major axis may be perpendicular to the rail surface centerline. For each leaf nozzle, the central axis may be directly downwardly from the horizontal and the major axis may be parallel to an elongated spray bar on which one or more leaf nozzles are mounted. For each third rail nozzle, the central axis may be directed downwardly from the horizontal and the major axis may be positioned vertically. The third rail nozzles may be mounted to the rear of the leaf nozzles to aid in leaf removal. Main water valves are remotely actuated by air to release high pressure water to corresponding sets of nozzles.

  • Patent number: 6065721
    Abstract: An sir blowing system for use in deeping railroad track switches clear of snow utilizes flexible tubes, preferebly of rubber or plastic, located transversely beneath the main tracks, and connecting with resilient nozzles to direct a high flow of air in the direction of the track switch points. The system may include resilient ducts conveying air in protective relation with the switch control rods, extending laterally beneath the track. The rod protective air discharge may be by way of a louvered cross-tube, extending parallel with the rods, to discharge air laterally of the rods, or one or more nozzles discharging air longitudinally of hte rods.

  • Patent number: 5802983
    Abstract: The present invention include a non-motorized low-profile platform cart system for transporting heavy equipment, machinery and vehicles to limited access areas. The system includes a low profile platform cart without motorization and a portable loading ramp for loading vehicles and such onto the cart. The cart may be moved by any motor power source with hi-rail capability other than train engines. The cart also has a rear plow which is capable of removing ballast and debris from the tracks. Use of the cart and ramp allow easy access to limited access areas such as construction areas and bridge repair areas, as well as limited access railway areas where there are no access roads. This invention produces a simple, highly economical solution to the problem of limited access.

  • Patent number: 5775228
    Abstract: At least one powered disc is suspended from a locomotive and applied to a rail surface for treating the rail surface ahead of driven locomotive wheels to increase adhesion between the driven wheels and the rail surface. Torque applied to the disc varies the rate of rotation of the disc away from that of a freely-rotating disc so that a significant level of creep may be maintained between the disc and the rail surface with substantially no angle of attack between the disc and the longitudinal axis of the rail. The torque may be generated through a second disc contacting the rail and coupled to the first disc with the first and second discs rotating with differing rates of rotation, or may be generated through a passive or active actuator coupled directly to the disc. The amount of creep between the disc and the rail surface and the direction of the creep may be varied in accordance with the level of contamination of the rail and the disc may be disengaged from the rail when cleaning is not required.
