SPECIFICATION forming part of Letters Patent No. 314.304. dated March 24, 1885.
Application lcd September 20, 18e-i.
(No model.) Patented in England June 7, 1882, No. 2,675; in France December 7, 1F82,
No. 152,487, and in Germany December 9, 1882, No. 23,992.
Our invention relates to a novel construe` tion and arrangement of a telephonie receiving-instrument, and to the combination therewith of any known transmitting-instrument.
The object of our invention is to produce increased efficiency in telephonie apparatus, and this we effect by the use of the apparatus which we now proceed to describe.
At each end of a suitable case we fix a plate and stretch between these plates an iron or steel wire, round which are closely wound two coils of insulated wire. One of these coils, which may be of coarse wire, connects the poles of a local battery. The other coil ,which is preferably of fine wire, is connected to the line at its one end and to earth at its other end.'
Vhen electrical undulations produced by pulses of sound on a transmitting-instrument of any known kind are sent along the line, the iron or steel wire of the receiving-instrument above described is acted on electro-magnetically, and its plates are caused to vibrate by conduction of the magnetic vibrations from the wire to the plates, reproducing the soumis which actuate the transmitter. It is conv enient to inclose the two plates of the instrument in casings, and lead from these casings ileXible tubes, so that the sounds can be conveyed to both ears. A transmitting-instrument of any known kind can be connected into the wire of the local batter'fy,and this transmitter will serve for sending to the distant station.
Figure .l of the accompanying drawings represents a telephonie receiving-instrument according to our invention, with its connections shown diagrammatically.
The instrument, as shown iii/Fig. 1, consists of a thin wire, A, of iron, steel, or other magnetic metal, attached to two disks, D D, which may be of thin wood, or of metal, or of other more or less sonorous material. On the wire A is wound, in the first place, an insulated conducting-wire, XV, completing the circuit of a local-battery B, in which circuit may be introduced any known telephonie transmitting-instrument T; also, on the wire A is wound, in the second place, an insulated wire, X, forming part of the line-circuit L L', communicating with a distant station.- Then electrical impulses are set up in the line L L' at the distant station by a telephonie transmit-ter, sounds corresponding with those that caused the impulses are emitted by the instrument shown in Fig. l.
The instrument may be connected as shown diagrammatically by Fig. 2.
The disks D D may form the ends of soundboxes S S, having flexible tubes leading from them to funnel-mouths E E, that can be held to both ears; also, the one wire NV may include in its circuit the primary coil of an inductorium, I, the other wire, X, including in its circuit the secondary coil of the inductorium.
Having thus described the nature of our invention and in what manner the same is to,
be performed, we would have it understoodthat we make no general claim to the use of an iron or steel wire coiled with a conductingwire for producing sounds under the influence of electric currents; but
IVe clainil. In a telephonie receiver, the combination consisting of two resonating disks, a wire or rod of magnetic material stretched between them perpendicularly to their faces, and a coil of insulated wire in an electric circuit surrounding the magnetic wire or rod.
2. Ina telephone, the combination of two resonating boxes, with a magnetic rod extending between and secured to the same, im inductorium having its primary in a local-battery transmitter-circuit, which also includes a coil upon the magnetic rodgand its secondary in the line-circuit, which includes another coil upon said rod, and exible listening-tubes pro- HARRY ROBERT KEMPE ceeding from the resonator -boxes, snbstan- `Vitnesses: tially as described.
