Abstract
A new and improved laser beam track alignment safety device with a tube having an inner surface and an outer surface. A first metal housing has an opening therein. The opening of the first metal housing is secured to the tube. An indicator means is secured within the first metal housing. A second metal housing has an opening therein. The opening of the second metal housing is secured to the tube. An indicator means is secured within the second metal housing. A restriction plate is secured within the inner surface of the tube. The restriction plate has a transmitting aperture formed therethrough. A plurality of securement means, each of which, couples around the outer surface of the tube and couple around the rail.
Claims1
A new and improved laser beam track alignment safety device for providing a safety device for railroad and trolley cars which monitors the alignment of the rails comprising, in combination:
- a tube having an open first end, an open second end, and an intermediate extent therebetween, the tube having an inner surface and an outer surface;
- a first metal housing having an opening therein, the opening of the first metal housing secured to the open first end of the tube;
- a laser transmitter secured within the first metal housing;
- a second metal housing having an opening therein, the opening of the second metal housing secured to the open second end of the tube;
- a laser receiver secured within the second metal housing;
- a restriction plate secured within the inner surface of the intermediate extent of the tube, the restriction plate having a transmitting aperture formed therethrough;
- a plurality of tie rods, each of the tie rods having a first end and a second end, each first end having an upper securement bracket and a lower securement bracket, the upper securement bracket and the lower securement bracket coupling around the outer surface of the tube and secured thereto by a fastening means, each second end having an inner bracket and an outer bracket, the inner bracket and the outer bracket coupling around a lower end of the rails and secured thereto by a fastening means with alternating tie rods securing to opposing rails, the plurality of tie rods being situated at interval points along the intermediate extent of the tube, the plurality of tie rods securing the tube at a position beneath an upper end of the rails at which a railroad or trolley car would be situated for travelling.
