UNITED' STATES PATENT OFFICE.
JAMES B. GOODING, OF WALTHAM, MASSACHUSETTS, ASSIGNOR TO STILI'JMAN WHITE, OF SAME PLACE.
PROCESS OF MAKING CALIPERS OR DIVIDERS.
Specilication forming part of Letters Patent No. 56,323, dated July 10. 1866.
To all whom if may concern Be it known that I, JAMES B. GooDING, of Waltham, in the county ot Middlesex and State of Massachusetts, have invented a new and useful Improvement in the Manufacture ot' Spring Calipers, Dividers, and other Like Articles; and I do hereby declare the same to be fully described as follows.
The common method of making spring calipers or dividers such as are represented in Figures l and 2 of the accompanying drawings is to forge the piece of metal in one long` piece of the shape required, or a close approximation thereto, and afterward bend the same at its middle, and in other respects into the necessary shape. This process is attended with so much bending of the metal at the middle or sprin g portion ot' the implement as to greatly strain and weaken it and render it liable to break either in the process of tempering it or While the article may be in use.
In carrying out my improved process of making such articles I first form, by means of dies or otherwise, a steel blank of the articlesuch, for instance, as is represented in top view in Fig. 3 and in side view in Fig. 4. Next I bore a cylindrical hole through the head and saw the blank lengthwise from its foot to such hole, and there reduce it to the shape exhibited in top view in Fig. 5. Next I open it or spread it into the shape as shown in Fig. 6, and subsequently give the requisite bend or form and nish to each of the legs-that is, as shown in Figs. 7 or S--after which I proceed to temper the spring in the usual manner.
Thus by iny mode or process I produce a very little strain or bend of the fibers of the metal at the spring or eye of the article in comparison to what it is subjected to by the common process of making such article; and,
furthermore, I not only am able to save metal-,ek
so made.
