  • Patent number: 9352760
    Abstract: A tread surface cleaning system has a cleaning element mounted to a truck frame of a steering truck in a position facing a tread surface of a wheel. The cleaning element moves freely to come into contact with and to move away from the tread surface. A pressing-load application spring biases the cleaning element toward the tread surface and a stopper restrains the cleaning element from approaching the tread surface. A forward and backward movement of a wheel axle 2 in the travel direction caused by steering is used so that the cleaning element makes contact only on the inner rail side toward which the tread surface of the wheel approaches when passing through a curved section. The cleaning element does not make contact on the outer rail side from which the tread surface moves away when passing through a curved section and when traveling through a straight section.

  • Patent number: 5775229
    Abstract: Invention relates to an on-board electrical generator system that may be retrofitted to existing railroad vehicles, such as freight cars, box cars, and the like, where rotation of the vehicle's axle powers the system. A preferred use thereof is to charge the battery for the electrically controlled brakes on the vehicle. Such vehicles typically include a chassis, having plural axles mounted thereon, and a journal box or adaptor block having a projection generally aligned parallel with the axles. Each axle contains a pair of wheels, which are inwardly mounted from the respective axle ends and rotatable with the axle. The generator includes a rotor fixed for rotative movement relative to a stationary stator, whereby such relative movement causes electric currents to be generated in the stator containing the generator in a non-rotatable housing.

  • Patent number: 5596937
    Abstract: It is frequently observed that when a real locomotive starts up, the front set of drive wheels commences to turn before the rear set of drive wheels begins to turn. The present invention is a simple device that permits this effect to be simulated in a model locomotive. The electric motor of the model locomotive drives a worm which turns a first gear. A second gear is mounted on the same shaft as the first gear but is not otherwise connected to the first gear. From the side of the first gear that faces the second gear, a pin extends at a particular radius. Similarly, two pins extend at the particular radius from the side of the second gear that faces the first gear. When the motor starts, the first gear turns immediately, but rotation of the second gear is delayed until the pin on the first gear strikes one of the pins on the second gear. In this way a delayed rotary motion is imparted to the second gear.

  • Patent number: 5562043
    Abstract: A system for moving a work element along a work surface for performing work thereon includes an elongated track of flexible plastic material formed with gear teeth along one edge thereof. A carriage having a drive motor and a drive wheel driven thereby, is moved along the track by the drive wheel engaging the gear teeth. The drive wheel is connected to the drive motor by an eccentric cam mechanism. The work element is carried by the carriage and preferably is a high-pressure fluid cutting device. The track is formed of a flexible plastic material such as a linear high density polyethylene, enabling it to bend and conform to the work surface, and has a second elongated strip of plastic material movably secured to the track and extending longitudinally therealong. A series of magnets are mounted on the track for adhering the track to the work surface. The magnets are attached to the track by fasteners extending through slotted openings in the second strip of the track when conforming to the work surface.

  • Patent number: 5220847
    Abstract: In a drive with twin helical drive gears on an axle driven by a motor with pinions at either end wherein the moto housing and axle housing are axially located by a key in mating keyways, an offset key is used to obtain axial housing adjustment by the amount of the key offset. The pinions are mounted to the motor with their teeth substantially aligned and the gears are mounted to the axle with their teeth substantially aligned, and the housings are axially positioned by an offset key to compensate for errors in tooth alignment to assure that gear backlash is centralized on both ends of the motor when the rotor is substantially centered in its range of end play.

  • Patent number: 5148754
    Abstract: A carriage lock selectively enables and prevents a mobile carriage from moving along rails embedded in a building floor. The mobile carriage includes a shaft on which are rotatably mounted a driver sprocket, a hub, and a handwheel. The hub mates with the driver sprocket. A chain and sprocket mechanism connects the driver sprocket with the carriage wheels such that rotation of the handwheel and hub causes the carriage to move along the rails. A locking knob is loosely captured between the hub and handwheel for being manually rotated through a predetermined angle relative to the hub and handwheel. A pin is translatable within the hub parallel to the shaft longitudinal axis. The pin has a head that is received within a selected one of two angularly spaced depressions in a cam formed on the locking knob. The depressions are also spaced apart in the direction of the shaft longitudinal axis.

  • Patent number: 5133265
    Abstract: A mobile carriage is movable along rails by manual rotation of a handwheel. The mobile carriage comprises a visual indicator that instantly informs a person of the locked or unlocked status of the mobile carriage. The visual indicator comprises at least one ridge on the handwheel and another ridge on a locking knob. The locking knob is loosely captured between the handwheel and a hub for selective rotation relative thereto between first and second end positions. The locking knob has a cam that slides a pin within the hub between first and second positions whereat the pin disengages and engages a stationary lock plate. When the locking knob is manually rotated to the first end position thereof, the pin disengages from the lock plate to enable handwheel rotation and carriage movement. Manually rotating the locking knob to the second end position thereof causes the pin to engage the lock plate and prevent handwheel rotation and carriage movement.

  • Patent number: 4913060
    Abstract: A running gear for an electric rolling stock has coupling devices for coupling the output shafts of traction motors to the input shafts of reduction devices which are provided with electrically resistive elements so as to prevent return current from flowing therethrough. Therefore, the coupling devices possess a higher level of resistance than the grounding resistance of the grounding devices, thereby enabling any return current to be prevented from flowing through the coupling devices. Thus, the running device can be kept free from electrolytic corrosion.
