UNITED STATES PATENT OFFICE.
EMERY M. HAMILTON, or NEW YORK, N. Y.
TELEGRAPH-SOUNDER.
SPECIFICATION forming part of Letters Patent No. 379,061, dated March 6, 1888.
Serial No. 200,444. (No model.)
To aZZ whom it may concern:
Be it known that I, EMERY M. HAMILTON, of the city, county, and State of New York, and a citizen of the United States, have invented certain Improvements in Telegraph- Sounders, of which the following is a full,clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to a telegraph-sounder or analogous telegraph instrument in which an armature'lever is vibratory between stops and has a retracting-spring; and my invention consists in the combination, with the said armature-lever and retracting-spring, of the devices hereinafter described, as and for the purpose specified, and as more at length recited in the claims.
Figure l is aside elevation, partly in vertical section, showing a telegraph-sounder containing my invention; and Fig. 2 is a crossscction on the line x 00, Fig. 1.
In the instrument shown in the drawings, A is the base; B, the magnet; O, the armature; O,the armature-lever, fulcrumed at c,and thus having a short arm, 0, and long arm 0 c and c are the stops between which the lever 0 vibrates, and G is the retractingspring.
D is a post set in the base ofthe instrument, and is exteriorly threaded, as shown, to re ceive the nut D, adapted to turn thereon, and thus move up or down the post. The post is provided or formed with a channel, (1, extending longitudinally of the post in its face at one side thereof.
E is an arm carried by a stem, 6, which is at an angle, and preferably at right angles, to the arm, as shown. This stem 6 is formed and adapted to fit into the channel din the post longitudinally and to slide therein, and its arm E extends across the perimeter of and preferably beyond the rim of the nut D, the stem 6 passing transversely of the bore of the nut, and its end opposite to that carrying the arm E being turned across the opposite perimeter of the nut, to constitute a heel or clamp holding the stem in engagement with the nut. The arm E is furnished withahook, d, for attachment detachably to the retracting-spring of the armature.
It is evident that the movement of the nut longitudinally of the post by turning it on its threaded seat thereon will cause the stem 6 to traverse the channel d in the post, and consequently carry the arm E toward or away from the armature-lever, and that, the retracting'spring of the armature-lever being hooked to said arm E, such described move ment of the stem 6 in the post will operate to increase or diminish the tension of said spring.
It is obvious that by means of my described devices the tension of the retracting-spring may be readily and quickly given a fixed adjustment relatively to the electric current in the instrument. And it is also obvious that, the magnet being set perpendicular to the base, as is desirable to give compactness and economy in the structure of the instruments, the post D may be set in the base perpendicular thereto, as shown, with the arm E reaching from the stem to the axial line of the retractingspring of the horizontal armaturelever, and be thus conveniently located in the instrument for manipulation by the operator, the running of the nut D downward increas ing and the running of said nut upward decreasing the tension of the spring, and the adjustment of thespring-tension being thus fixed at any degree or point desired.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In a telegraph-sounder,the combination, with the armature-lever vibratory between stops, and its retracting-spring, of a postfixed in the base of the instrument and provided with an exterior thread and a channel extending longitudinally of its exterior surface, a nut adapted to turn upon the thread of the post, astem adapted to fit into and slide in said channel and having an angle end engaging it to said nut, and an arm carried by said stem and extending at an angle thereto and adapted to be attached to said retractingspring, as and for the purpose set forth.
2. In a telegraph-sounder, the combination, with the armature -1ever vibratory between stops, and its retracting-spring, of the threaded and slotted post D, the nut D, and the arm E, connected to said spring and attached to said nut by rod e and angle end e, all constructed and arranged to operate as and for the purpose specified.
EMERY M. HAMILTON.
