  • Patent number: 7216590
    Abstract: A bulk loader conveys articles in bulk and has a hopper configured for receiving the articles, such as railroad articles. A reciprocating member is configured for reciprocating between a retracted position and an extended position in a track associated with the hopper. Articles that are loaded into the hopper fall into the track when the reciprocating member is in the retracted position and are conveyed from the hopper when the reciprocating member actuates to the extended position, resulting in the removed articles being positioned in a convenient location for further handling by an operator.

  • Patent number: 6095053
    Abstract: A bulk loader conveys rigid, stick-like articles in bulk. The bulk loader has a bin for holding a plurality of the articles and a trough connected to a bin having an entrance portion for receiving the articles from the bin and a discharge portion for discharging the articles. An auger, with an inlet end and an outlet end, is rotatably positioned in the trough so that the inlet end is positioned near the entrance portion and the outlet end is positioned near the discharge portion. Upon rotation of the auger, the auger conveys the articles from the entrance portion to the discharge portion. The trough is constructed and arranged to prevent conveyed articles from becoming jammed between said auger and said trough.

  • Patent number: 5730060
    Abstract: An apparatus for removing a rail anchor from a rail, the apparatus constructed and arranged to be mounted on a railway maintenance vehicle having a frame, and including a scraper for applying a preload against the anchor and for removing the anchor from the rail, and a pusher insert for applying vertical pressure against the anchor to impact and dislodge the anchor from the rail. An improved method for removing a rail anchor from a rail involves applying a preload or a horizontal scraping force against the first, curved end of the anchor with the scraper, applying vertical pressure against the second, knobbed end of the anchor with the pusher to impact and dislodge the anchor from the rail, and removing the dislodged anchor from the rail with the scraper.

  • Patent number: 5671679
    Abstract: A system for detecting targets and for positioning at least one work module over a particular target to perform a task thereon. The system includes a movable machine having a main frame, a drive mechanism for propelling the machine across a base surface, a sensor associated with the machine for detecting locations of at least one target positioned on said base surface, and an encoder assembly associated with the machine for obtaining motion data. The motion data includes at least one of the displacement and velocity of the machine across the base surface. Also included is a control unit for receiving the target locations from the sensor, for receiving the motion data from the encoder assembly, for determining a target distance for the drive mechanism to propel the machine such that the work module is generally aligned with a particular target in a target area, and for creating a destination signal indicating when the work module is operationally aligned with the target area.
