Rail Interlock Patents (Class 104/246)
  • Patent number: 4155434
    Abstract: A rail electrification system for electric railways utilizing 3-phase power, comprising three conductor rails arranged in a group characterized by a staggered relationship, commonly known as a delta configuration, so that two of the rails face in one direction and the third faces in an opposite direction. For taking off the 3-phase power from the conductor rails, the car is equipped with two sets of three collectors or shoes each, with the sets being disposed on opposite sides of the conductor rail group. Three of the collectors (not all in one set) function when the car is traveling in one direction along the rails, whereas the remaining three collectors function when the car has been turned around and is traveling in the opposite direction along the rails.

  • Patent number: 4092928
    Abstract: Traveling support apparatus for supporting welding device or other apparatus for peripheral travel about a pipe. The support apparatus utilizes endless belts disposed around paired wheels at opposite sides of the apparatus to propel the apparatus along a track. The endless belts are pivotally supported for equal pressure engagements with the path along which the support apparatus travels. The support apparatus engages opposite sides of a track in the form of a strip or band spacedly surrounding a pipe to support a frame which is held firmly against movements toward or away from the track so that the supported apparatus is reliably held in position with relation to the pipe.

  • Patent number: 4056064
    Abstract: A gantry loader comprising a horizontally disposed support beam, a railway rail secured to the support beam, the rail including a head, a loader assembly including a carriage selectively displaceable along the beam, the carriage having a first pair of wheels for rollingly engaging the face of the rail head, a second pair of wheels for rollingly engaging one projecting portion of the head, a third pair of wheels for rollingly engaging the other projecting portion of the head, each of the third pair of wheels including a peripheral step selectively facing the first pair of wheels and having a beveled side wall surface, the third pair of wheels being selectively displaceable from a retracted position remote from the rail to an advanced position whereat the base and the beveled side wall surface of the step engage the other projecting head portion, and means for selectively maintaining the third pair of wheels at the advanced position.

  • Patent number: 4044688
    Abstract: There is disclosed a monorail transport apparatus for transport of golf equipment in golf links, comprising a transport vehicle body provided with a caster wheel rollable on a monorail, a driving vehicle body equipped with a prime mover and partly received in and pivotally connected to the front portion of the transport vehicle body so as to be swingable around the axis of a transverse shaft, a driving wheel and a driven wheel disposed on both sides of the transverse shaft, an endless driving belt entrained around the driving and driven wheels and pressed against the upper surface of the monorail, and an auxiliary wheel pivotally connected to the driving vehicle body so as to be swingable around the axis of the transverse shaft and pressed against the lower surface of the monorail, the arrangement being such that the transport apparatus travels while holding the monorail from above and below between said driving belt and the auxiliary wheel, thereby achieving increased hill climbing ability and increased trav

  • Patent number: 4007693
    Abstract: A train system particularly adapted to be used in tunneling operation to outwardly move the loosened earth and rock or muck and, for that purpose, which is trackless and takes its lateral guidance from the usual utility duct which is required along the tunnel. This trackless train system also distinctively includes wagons having each a walking beam suspension which supports the load carrying ground wheels in a longitudinal central row, such that the wagon adequately and undistinctively rides on a tunnel floor which is uneven or which has a transversely concave profile, such as to form an underground conduit.

  • Patent number: 3931687
    Abstract: An ejector roller and guide arrangement having a pair of rollers beveled on their outer edges, one on each side of the ejector frame, which travel between horizontal upper and lower tracks mounted on the pusher frame. The beveled edges of the rollers ride on inwardly angled surfaces of the track. Separate rollers on inwardly angled axes of rotation roll on separate track secured to the side walls of the bowl having outwardly angled surfaces. The longitudinally spaced rollers provide lateral and vertical guidance of the ejector in moving into and out of the scraper bowl for ejection of the earth material.
