ELECTRIC SIGNALING-INSTRUMENT.
SPECIFICATION forming part of Letters Patent No. 231,794, dated August 31, 1880.
Application filed Aprii17, 1880. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM HADDEN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Electric Signaling-Instruments, of which the following is a specification.
Figure l is a face view of the instrument. Fig. 2 is a section through the line a; 00, Fig. 1. Fig. 3 is a section through the lineyy, Fig. 2.
Similar letters of reference indicate corresponding parts.
The object of this invention is to furnish electric signaling-instruments so constructed that the circuit-closer will be stopped automatically as soon as the signal has been given, and held in place until the signal is to be repeated.
The invention consists in constructing an electric signaling-instrument ot'a nonconductin g block having a ring-groove, and in the bottom of the said groove contact-points connected with the circuit-wire, the crank-arm having contact-spring, a stop to receive the crank-arm of the circuit-closer, and a recess to receive the end of the contact-spring, whereby the circuit-closer will be prevented from moving farther than a complete revolution, and the contact-spring will be taken out of tension, as will be hereinafter fully described.
A is a circular block or plate, of wood or other suitable non-conducting material, which is designed to be secured to a table or wall by screws or other suitable means. In the face of the block A, at a little distance from its edge, is formed a ring-groove, B, in the bottom of which are placed contact-points G D D. The contact-points G D D are connected with one part, E, of the circuit-wire at the rear side of the block A. The first contact-point, 0, is made long to give time for the magnet at the receiving end of the line to set the recording mechanism in motion. The other points, D D, are arranged in groups to give the required signal. \Vith the arrangement shown in the drawings the signal one/ five, would be given. The other part, F, of the circuit-wire is connected with the lower end of the pivot Gr, upon the upper end of which works the crank-arm H, which is provided with a nonconducting handle, I.
To the outer end of the crank-arm H is attached the end of aspring, J, the other end of which rests and slides upon the bottom of the groove B, and is held down against the said bottom by its own elasticity, so as to make a sure contact with the points 0 D D as the crank-arm H is turned around upon the pivot Gr.
To the side of the block A, at a little distance from the forward end of the elongated point C, is attached a stop-arm, K, upon the inner side of the upper end of which is formed a shoulder, for the outer end of the crankarm H to strike against as it completes a revolution. The crank-arm H is released from the stop K and allowed to move forward by pressing its outer end below the shoulder of the said stop K.
In the bottom of the groove 13 is formed a recess, L, at such a distance from the stop K as to receive the end of the spring J when the outer end of the crank-arm H rests against the stop K, to take the tension off the spring J when the instrument is not in use, and to adapt the said spring J to serve as a pawl to prevent the crank-arm H from being turned backward.
In using the instrument the outer end of the crank-arm His pressed down to release it from the stop K, and the said crank is then turned around upon its pivot G, the tension of the spring J bringing it in close contact with the contact-points G D D as it passes over them, closing the circuit as many times as there are contact-points and at intervals corresponding with the distance apart of the said points.
Havingthus described my invention, I claim as new and desire to secure by Letters Patent- 1. An electric signaling 4 instrument constructed substantially as herein shown and described, consisting of the noneondnctin g block A, having contact-points O D D, connected with the circuit-wire E, the pivot G, connected with the circuit-wire F, the crank-arm H, having spring J, the stop K, and the recess L, as set forth.
2. In an electric signaling-instrument, the stop K, attached to the block A, having ringgroove B and contact-points (J D D, to receive the crank-arm H of the circuit-closer and stop its movement, substantially as herein shown and described, whereby the circuit-closer is kept from again coming in contact with the contact-points during the same movement, and thus confusing the signal, as set forth.
3. In an electric signaling-instrument, the recessL, formed in the bottom of the ringgroove B, having con tact-points to receix e the end of the spring J of the circuit-closer, substantially as herein shown and described,
