Description: |
"Carriages for heavy sawing are usually mounted on rollers or wheels with flanges running on parallel rails analogous to ordinary railroad-tracks. With machinery of this character, subjected to rough usage, it is not easy to avoid irregularities in motion from various sources, particularly from end-play of the wheels."I have devised and wrought out in practice means for carrying the carriage with exact uniformity, not only while new, but also after the parts have been subjected to any ordinary amount of wear. I make the bearing tapering. The gravity of the heavy carriage and of the log thereon holds the carriage centered exactly upon the wheels under all circumstances. Taking care to make the rail straight and of uniform width, and to adapt the flanged rim of the wheel accurately thereto, I can depend on the traverse of the carriage being exactly rectilinear and always in a uniform path." |
