ABSTRACT:
The present invention involves a power saw for cutting railroad rails at an angle. The power saw includes a base, a cutting location disposed proximate the base, a cutting disc and associated driving mechanism, and a device for moving the cutting disc and changing the angle of the cutting disc relative to the cutting location. A table supports the cutting disc and driving mechanism, and the base has two pivots selectively engageable with the table. The driving mechanism of the cutting disc includes a cam based oscillating device for oscillating the cutting disc during cutting of a railroad rail. The power saw also includes a guide and a conveyor system for positioning a railroad rail on the cutting location. The conveyor system moves railroad rails to the guide. A device for applying force against the direction of the cutting force of the cutting disc is located at the cutting location. A device for delivering a fluid, a coolant, lubricant, or rust-inhibiting solution, is located adjacent to the cutting disc. A device for aligning the cutting disc with the cutting location maintains the low point of the cutting disc in alignment with the cutting location. The resulting joint for a railroad rail comprises a pair of rails having matching ends disposed at an angle in the range of about: 50.degree. and 30.degree., a dielectric material disposed between the ends, and a bar attached to and connecting the rails.
