Definitions
- My invention relates to what I term an electro-harmonic telegraph, and is based upon the fact, well known to electricians, that an electromagnet clongates under the action of an electric current, and contracts again when the current ceases; consequently a succession of impulses or interruptions will. cause the magnet tovibrate, and if these vibrations be of suflicientfrequency a musical tone will be produced, the pitch of which will depend upon the rapidity of the vibrations.
- the object of my present invention is to utilize this discovery for the transmission of intelligible si nals to a distance by electricity
- Figure 1 represents an arrangement upon circuit of apparatus which I use for carrying'out the objects of my invention, the transmitting part of the apparatus being shownin plan and the .receiver in perspective; and Fig. 2 represents a view, in elevation, of the transmitting apparatus, Fig. 3, an end view thereof, and- Fig. 4 a detail view of one of the rheotomes.
- ihe transmitting apparatus is mounted upon a suitable frame or base, A.
- An ordinary induction-coil, B has the usual primary and secondary circuits to b.
- Automatic vibrating electrotomes O G of the usual construction.
- an eleetro-niagnet, E is placed in circuit.
- cylinder or resonator, S, of metal, is placedon the poles of the magnet.
- This resonator is composed of a circumferential baud having two end walls, disks, or
- .that is, one capable of responding to or reproducing tones of all kinds.
- W hen electrotomes of different pitch are successively operated, their tones will be correspondingly reproduced by the receiver and when two or i nore electroiomesrnre simultnneously sounded the tone of eschwill still be reproduced without confusion inthe sounder or resonator S, by which means I an enabled to reproduce composite tones, melodies, or tunes.
- Mechanical circuit-breakers may be substitnted for-the antomatically-vibrating elcetro' tomes hereiubei'ore described. I have, in fact,
- the receiver is shown and described as operated by the induced current of the secondary coil; but the secondary or extra our" rent of the primary coil may be used instead thereof with good efiect.
- the above-described apparatus is especiallyadapted to telegraph on long land and submarine lines.
- Byit letters and signals can be represented by tonesdiflering in pitch; or the ordinary Morse signals can be made by short and long interruptions in a prolonged tone of the same pitch, thus insuring great rapidity of truusmissiou.
- Thesonnd-intensifying chamber or resonator having a disk or diaphragm of metal,responsive to rhythmical impulses or vibrations representing musical impressions or sounds intervention of the electro-megnet, substantially as set forth. 3.
- Thesonnd-intensifying chamber or resonator having a disk or diaphragm of metal,responsive to rhythmical impulses or vibrations representing musical impressions or sounds intervention of the electro-megnet, substantially as set forth. 3.
- thetra-nsmitter consisting of a coil of helix, v. hereby rhythmical electrical impulses or vibrations may be induced in the telegraphic circuit without interrupting the continuity of the same
- the receiver consisting of the electro-magnet, having the metal disk or diaphragm for its armature, these being arranged to yibrate in unison with each other, and with the impulses or vibrations pro (reading from the transmittingor inducing coil, substantially as set forth.
