c: TRIBBY.
Improvement in Watch Case Springs.
Patented FebI2O, 1872.
UNITED STATES PATENT OFFICE.
CHARLES TRIBBY, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO HIMSELF AND JACOB HOOVER, OF SAME PLACE.
IMPROVEMENT IN WATCH-CASE SPRINGS.
Specification forniin g part of Letters Patent No. 123,798, dated February 20, 1872.
To all whom it may concern:
Be it known that I, CHARLES TRIBBY, of Washington, in the county of Washington and District of Columbia, have invented a new and useful Improved WVatch-Case Lifting-Spring; and I do hereby declare that the following is a full, clear, and exact description thereof, sufficient to enable those skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanyin g drawing making part of this specification and to the letters and figures marked thereon.
The nature of my invention consists in makin g a watch-case liftin g-sprin g of brass instead of steel; and also in the peculiar construction and arrangement of the spring, as hereinafter particularly described.
In the accompanying drawing, Figure 1 is a top view, partly in section, of a watch-case with my improved lifting spring attached. Fig. 2 is a sectional view of the same taken in the line as 00 of Fig. 1. Fig. 3 is a detached View of the spring.
spring is not greater than that of the narrowest portion of the ordinary steel spring, so that the spring fits snugly in the groove which runs around the inside of the case, and is entirely out of the way of the movement and the catch which holds the cap when closed.
The spring is hardened by rolling, drawing, or hammering, the proper tempering being thus obtained. In order to give it sufficient play, it is bent or curved, as shown at a a a in Figs. 2 and 3. The spring occupies about one-fourth of the groove on the inside of the case, and is held in place therein by a pin or screw passing through the case and bearing against the spring, instead of passing through it. The large end of the springArests against the large end of the spring which forms the catch for holding the cap when closed. The pin or screw Bis placed about midw ay between the center and small end of the spring A.
What I claim as new, and desired to secure by Letters Patent, is
The brass lifting-spring A, formed with the curves (0 a a and held in place by the pin or screw B, placed in front of instead of passing through it, all as herein shown and described.
' CHARLES TRIBBY.
