Improved Scroll-Saw.
In the accompanying engraving we give a very clear representation of an improved scroll-saw invented by Mr. J. W. Moyer, and manufactured by Messrs. Hampson & Copeland, of 42 Cortlandt Street, New York. The objections to the common gate-saw are numerous and serious, while in the saw under consideration the table being free from all obstruction, the stuff can be fed much more conveniently, and larger and more complicated articles can be cut, and better work done.
The saw, which is completely free from all lateral deflection, has a perfect and uniform tension at all points of the stroke; and is guided by hard-wood crossheads, running on steel rods, this arrangement having been proved by experiment to be the best for the purpose. After the saw is “hooked on” and the springs properly adjusted, the tension is perfect; a condition which is obtained by the use of two springs, an upper and a lower. These springs are made of India rubber three and a half inches in diameter and transmit their tension to the saw through the levers seen in the cut. The tension of these springs can be readily and quickly adjusted by means of the nuts on the rods, which connect the levers with the spring bar. So perfectly do these various devices perform their work that the saw can be moved one thousand times per minute, and even more, at a stroke of five inches, without jar or noise. In practice, however, it is found that from 600 to 750 revolutions per minute is about the proper range of speed.
An examination of these saws, as furnished by Messrs. Hampson & Copeland, shows a praiseworthy attention to the quality and distribution of the material that enters into their construction. They are made in a substantial and workmanlike manner, the working parts being of malleable iron and steel, and with an iron or wood frame, as a heavy or light machine is needed. They must prove indispensable to every well-furnished woodworking establishment.
