The Newton Machine Tool Works, of Philadelphia, built a series of model machines for cutting off, covering every possible requirement and making a very interesting exhibit. A few years ago, this class of tool was unknown in the United States, except by scattered specimens of English machines. When the demand came for them they were promptly built, each problem being thoroughly solved, and in a way, to my mind, far in advance of European practice. The Newton No. 4 cold saw cutting-off machine, Fig. 6, will serve to illustrate the line. Of this tool the makers write: — “These machines are built in all sizes, from the small machine, cutting up to a limit of 2 inches, to the largest size, which has a capacity for cutting round sections up to 21 inches. These machines are now in universal use throughout the different machine shops, and the large forging shops are finding greater economy in using these machines on straight work than in using slotting machines. This No. 4 machine has a capacity for cutting square sections up to 12 inches, or is capable of cutting a slab 12 inches high by 38 inches long. The saw on the machine is 36 inches in diameter. The feed mechanism is arraigned to have a feed one-eighth of an inch per minute on the slowest, up to 1 inch on the fastest feed. This is controlled by a lever, which can instantly change the feed from one extreme to the other. The periphery of the saw runs at all times at the same speed. For ordinary work the saw travels 85 feet per minute. Where the machines are sold for cutting hard or irregular stock, such as high-carbon rails, we reduce the speed to 65 feet." |
