Definitions
- This invention relates to a gauge hywh'ich aflwatch maker is enabled to compolre the strength of different springs in such a. manner that if thesp'rih glbi a watch breaks it is. easy to find another of equal power to take itsi place.
- My gauge consists of a chamber A, which may .be square; or-of any pthenform' or shape; to which access :ishad through a slot, a, in its edge, which is Inge enough to admit theend of the sprihg to'be" tried.
- a lever, b whichjhhs' its fulcrum on a pivot, c, and the loose eiid of which is'bent up and projectsthrough'a segmentalslotfin the face of -the chamber, forming an index whichtraverses over' the scale d;
