Watch Making Machinery
The remarkable increase in the manufacture and sale of American watches is having its natural effect in stimulating the ingenuity of the men who make the tools with which the watches are made. This, in turn, by introducing new and valuable labor-saving devices, tends to enable the watch-making companies to produce better and more accurate work at a lower price, and to swarm upon the watch-buying public in the lively way that brings trade and prestige.
One of the latest competitors, for the confidence and patronage of watch and clock making companies and of jewelers and watch makers and repairers generally, is the Sawyer Watch Tool Company, of Fitchburg, Mass., a number of whose tools are illustrated herewith.
The pinion cutting engine, shown in the cut, is designed for cutting the teeth in small pinions. It has a revolving head with three spindles, each spindle running in a quill or shell, made from the finest steel, hardened, | and has double taper bearings. The spindle is also of hardened steel, ground lo fit the quill, has a fine combination of adjustments, and can be set with great accuracy. On the back end of each spindle is a gear. In revolving the head the driving need not be stopped, as the gear on the end of the spindle will connect with the driving gear while in motion, which facilitates the working of the machine and adds to its daily production.
The automatic leaf polisher is designed for polishing the leaf or teeth of pinions. It can he set to make so many strokes a tooth; it also can be set to polish so many teeth (or as many teeth as may be in the pinion), and not run by and polish one tooth the second time, which would cause an imperfection in the pinion. It rotates the pinion itself, that is, as soon as a tooth is polished, it turns the pinion around to the next tooth, and is arranged to plane the form on the polisher without removing it from the machine. It has all the necessary adjustments for its particular use.
The automatic staff and pivot turning machine is designed for turning staffs and pivots, and is capable of doing a great amount of work. It can be adjusted to produce staffs and pivots in quantity of exact size. The machine will do the turning while the operator is preparing another piece of work to put in it, and the process is repeated. Every staff is turned upon dead centers, thereby insuring them to be perfectly true. It can be set to turn straight or taper, and to square up the shoulders, and has every adjust meat necessary to facilitate Its working, and produce accurate work at a very small cost. |
