EDWARD RIVETT, OF BOSTON, MASSACHUSETTS.
HAIR-SPRING STUD FOR WATCHES.
SPECIFICATION forming part of Letters Patent No. 224,227, dated February 3, 1880.
Application filed December 11, 1879.
To all whom it may concern:
Be it known that I, EDWARD RIVETT, of Boston, in the county of Sutl'oll; and State of Massachusetts, have invented a new and useful Improvementin Hair-Spring Stud, of which thetollowing is a specification.
The nature of my invention consists in combining with hair-spring stud, which has a kerf extending from its upper end nearly to the lower end, projecting arms which bear on one side of the plate, ih e bearing-points being near their outer ends. To hold this stud in place, its lower end extends entirely through the plate, and is held by a screw-nut. As the outer ends of the projecting arms reston the plate, any considerable force exerted by the screw-nut to draw the stud down will cause the arms to incline upward, and thus throw that half of the stud to which they are attached in toward the other half-that is, the kerf will close up and securely grasp the hairspring.
In the drawings, Figure 1 is a plan of a watch-plate. Fig.2 is avertical section,showing the stud and a part of the plate. Fig. 3 is a plan, showing the recess in the plate. Fig. 4 is a plan of the stud. Fig. 5 is a perspective view of the stud and its screwaiut.
Let A represent the watch-plate, which is provided with a rectangular sinkage, B, Figs. 2 and 3, and has a hole, I), in the center of this sinkage, which extends entirely through the plate.
The hairspring stud L, Figs. 1, 2, 4, and 5, is made as shown in the drawings, having a kerf, K, extending nearly through its length, and two projecting arms, E E, Figs. 2, 4, and 5. These projecting arms E E are so made,
in connection with the recess in the plate, that their outer ends only bear upon the plate.
H is a screw-nut, which is attached to the lower end of the stud and serves to hold it firmly in place.
To give more elasticity to the sides 0 U of the stud, l file away a portion of the metal at the points M M, as shown in Fig. 2, immediately under the arms E E.
My hair-spring stud operates as follows: It is inserted in the plate, as shown in Fig. 2, and the screwnut H is turned onto it, but not sufficiently tobring any strain upon the arms E E. Now the hair-spring is inserted in the kert' K, and the nut H is turned on more firmly. so as to draw the stud down. This action will have a tendency to force the ends of the arms E E upward, which action willcause the parts 0 and (J to incline toward each other, and thus close up the kerf and firmly grasp the hair-sprin The recess B in the plate A (see Fig. 3) receives the projections E E, and thus prevents the stud from turning.
I claim 1. In a clock or watch, the kerfed stud L, having the projecting arms E E and screwnut H, operating together substantially as described, and for the purpose set forth.
2. In a clock or watch, the kerfed stud L, having projecting arms E E, in combination with the recessed plate A 13, substantially as described, and for the purpose set forth.
EDWARD RIVETT.
