IMPROVED METHOD OF TEMPERIIITG SPRINGS.
(its glilltlllllt ttftt'tth' in in time ittttets 33am imh matting part at tlge same.
TO. ALL WHOM IT MAY CONCERN:
Be it known that I, WALLACE BARNES, of Bristol, county of Hartford, and State of Connecticut, have invented certain new and useful improvements in the Method or Process of Tempering Springs; and to enable others skilled in the art to make anduse the same, I will proceed to describe it by referring to the drawings, in which the same letters indicate like parts in each of the figures.
The nature of this invention will be understood from the specification and drawings. The object desired to be attained by this invention, in addition to securing a true even position to the edge of the spring, is also to secure a true expanded coil, and at the same time secure an erect position to the edge or width of the spring, through its entire length; while in the tempering process, which is performed by placing the spring between metal plates having their surfaces (one or both) corrugated or perforated so as to allow the tempering fluid to flow freely between the expanded coils which support and hold the springs arranged therein in an erect and expanded position, or in the desired shape between said plates, while they are immersed in the tempering fluid.
In the accompanying drawings are shown two metal coils a a, which may be formed expanded or contracted more or less, as desirable. Between these coils arrange thesprings a, after hardening, and previous to the process of tempering. In this way one or more springs may be tempered together by adding one or more coils to hold them in the desired position, so that whatever the shape of the spring may be after hardening, its true fixed position will be secured in the process of tempering. The advantage of this invention is insecuring, in
addition to a perfect and even temper to the spring, a true expanded coil, together with a true even edge of the spring.
The difficulty of hardening and tempering springs, particularly light springs, cannot well be described, or fairly comprehended exeeptby persons who have made the effort to harden and temper such springs. perience in hardening has shown tha t they (the springs) will twist and curl into almost ever conceivable shape. Heretofore large quantities of springs have been imported and sold at prices which would preclude the possibility to compete therewith. But by this process, as above described, I can not only compete with the prices of the imported article, but I can also make a good remuneration, and produce a better and cheaper article for trade and use. 7
I believe I have thus shown the nature and process of operation, so as to enable others skilled to make and use the same.
What I claim, therefore, and desire to secure-by Letters Patent, is-
The employment of one or more coils, as shown and described, in the process of tempering springs.
WALLACE BARNES.
