  • Patent number: 4090453
    Abstract: Apparatus for rerailing derailed wheels of a railway vehicle includes a bridge which is positioned beneath a derailed vehicle end. After the vehicle is leveled, a lifting jack disposed on a carriage mounted on the bridge supportingly elevates the derailed vehicle end and moves the supported derailed end over the rails, the bridge being positioned to return the derailed vehicles to a position over the rails. Since the wheels of the opposed vehicle end are stationary, the derailed vehicle end is moved along an arcuate path. A motive means such as a jack moves the carriage along the bridge axis, and supporting roller means on the carriage enable the lifting jack engaging the vehicle to move transversely to the bridge axis thereby allowing the jack and supported vehicle end to traverse an arcuate path while fully supported.

  • Patent number: 4082198
    Abstract: The apparatus of the invention is capable of loading, transporting and shredding a large bale of material. The apparatus is of a vehicle trailer type and is equipped with a box or housing unit type that is open only at the rear side of the vehicle. The apparatus has a combination tailgate and lift structure which functions as a fork lift to load and move a bale of material into the housing unit and, after such delivery, to automatically function as a tail gate to close the rear side of the housing unit. A floor conveyor within the housing moves the baled material forwardly into the path of a bale shredder which is of a flail type. The shredded material is then blown or moved by the shredder into an auger at the forward end of the housing unit for discharge into a feed bunk or storage bin.

  • Patent number: 4081091
    Abstract: A lift device particularly suitable for lifting handicapped persons with or without wheelchairs, into a vehicle or building. The lift can be incorporated into the doorway of any given vehicle, or into any step structure within a building. The lift, in its stowed position, forms the normal steps. The platform is made of three hinged parallel sections which can be withdrawn and folded into two steps. A ramp normally hidden under the steps slides forward to allow easy access to the extended platform and a safety flap housed in the ramp flips upward to form an angle stop preventing the wheelchair from rolling backward during platform motion.

  • Patent number: 4080903
    Abstract: The invention is a method of and apparatus for continuously laying sleepers at permanent positions at predetermined intervals on a bed of ballast for a railway track, by means of a vehicle travelling along the track, which method comprises feeding each sleeper in turn from a stock of sleepers to a laying mechanism where the sleeper is held a little above the level of the bed of ballast, removing vertical support from beneath the sleeper at a position in advance of the intended permanent position of the sleeper so that the sleeper falls onto the bed of ballast in advance of its intended permanent position, drawing the sleeper along the bed of ballast until it reaches its intended permanent position and then completely releasing the sleeper in its intended permanent position. The invention permits the sleepers to be laid with greater accuracy than when using prior apparatus.

  • Patent number: 4080904
    Abstract: A pair of laterally spaced wheel chocks are each normally connected in a gap in a railroad track rail, with each chock having a straight upper surface over which car wheels can roll in crossing the gap. Pivotally connected on a horizontal axis to each chock is the rear end of an arm, the front end of which is pivotally connected to a support. Means are provided for lifting the chocks after car wheels have rolled across them, whereby to cause the chocks to engage a pair of car wheels and move them forward on the track. The arms guide the upwardly-moving chocks in paths that result in there being substantially no sliding of the chocks against the wheels.

  • Patent number: 4078724
    Abstract: A rail mounting assembly is disclosed including clip members which is some cases have formable portions for effecting engagement with a base plate to retain the clip member in position on a crosstie with the base plates on opposite sides of the rail being connected by an anchor means extending internally of the crosstie. Another aspect of the invention involves clip members and base plates having engageable serrated surfaces clamped together by a bolt received in a threaded anchor in a concrete crosstie so that loosening and subsequent tightening of the bolt permits the adjustment of the clip members with respect to the radial base flange and another embodiment in which a clip is held in position by a bolt in the anchor member in the crosstie with the clip having a coined surface canted at an angle to accommodate rail tilt and sawtooth serrations engaging the bolt head for preventing loosening of the bolt member.
