New Tenoning Machine.
The amount of attention that has been given to the design and construction of woodworking machinery would seem at first sight to leave but little chance for further improvement. Woodworking machinery in all probability ranks as high as any line of machinery made in the world in point of design, construction, economy of action and in numerous other desirable features. However, the records of the Patent Office show that continual progress is being made in the direction of improving this very important line of labor-saving devices. The changes that are being made are for the most part in the direction of economy of material and of better quality in the work produced. Among recent improvements to which our attention has been called is that of a. new tenoning machine, recently put upon the market by Messrs. Jos. O. Colladay & Bro., 626 Race street, Philadelphia, a general view of which is afforded by Fig. I of our engravings. The machine is built entirely of iron and steel, and, as may be seen from the engraving, is solid and substantial. One of the recent improvements incorporated in this machine, and which was patented only a few weeks since, is the device by which both heads may be raised or lowered together or separately. The copes are attached to the head-stocks on which the cutter heads hang, and need no separate setting. In other respects this machine has all the improvements and adjustments necessary for convenient and efficient use, and is a first-class tool throughout. The tight and loose pulleys are 9 inches in diameter with 4-inch face, and in operation are intended to make 900 revolutions per minute. |
