Abstract

Apparatus for continuously monitoring the gage of a railroad track from a vehicle on said track comprising measurement means which continuously measure the distance between the rails of a railroad track and remote indication means which display data of said measurement means to a vehicle operator.

Claims

1. Apparatus for continously monitoring the gage of the rails of a railroad track from a vehicle on the track comprising:

an extra-vehicular frame having two arms extending therefrom, said frame further comprising an elongated horizontal member with substantially identical vertical arms extending from each end thereof;

a distal vertical plate secured at the end of each arm;

an inward facing yoke adjustably secured to each distal plate;

measurement means pivotally mounted to said yokes, said measurement means further comprising a horizontal telescoping rod having pivotally connected to each end thereof, a vertical telescoping multiple wheel member, each wheel member being pivotally secured at about its midsection to one of said yokes, and a tension spring interconnecting portions of said wheel members near said telescoping rod and drawing said portions toward each other, further provided that said wheel members do not support the weight of said vehicle, with said wheel member further comprising an elongated portion which houses a wheel mount and a compressed spring which presses said wheel mount away from said elongated portion in a telescoping manner, said wheel mount further comprising a top wheel for contacting the top of a railroad track rail in a rolling manner and an inside wheel for contacting the inside of a railroad track rail in a rolling manner;

measurement indication means remotely connected to said measurement means; and

means for securing said frame to the rear of a railroad vehicle.

2. The apparatus of claim 1 wherein said inside wheels continuously press laterally away from each other, thereby continuously contacting the inner surfaces of a pair of railroad rails.

3. The apparatus of claim 2 wherein said horizontal telescoping rod is connected to a contact plate such that movement of either telescoping portion of said rod causes change in the engagement of said contact plate.

4. The apparatus of claim 3 wherein said measurement indication means is connected by said contact plate by communication means which causes gage variations sensed by said contact plate to be indicated at said remote indication means.

5. The apparatus of claim 4 wherein said means for securing said frame to the rear of a railroad vehicle further comprises a means for attachment of the present apparatus to said vehicle in an inverted manner for transportation thereof.
