To all 'u ho'my 'it may concern;

Be it known that Fn'ANcrs JOSEPH McCAu'rY, deceased, ormerlya citizen of the United States, residinf,r in the city and county oi San Francisco, State of,

the following is a specification. L

This' inventionrelates to an apparatus by' which sonorous vibrations be transmitted without the i aid of wires or other mechanical intermediateconnections between the stations.

It consists in the combination of devices, and in details oi construction which will be more fully explained hy reference to the accompanying drawings, in whichthe figure is a diagrammatic view illustrating the in vention.

In this invention an induction coil. is employed having a secondary winding A, and two primary windings 2 and 3. manner to the two sides o a spark gap 4.

5 is a suitable source oi electrical energy,.and one of the primary coils 2 is put in series with this source of electrical energy, and.A the 'current while flowing through this primary, is continually' varied by an'in terrupter 'as indicated at `6. The other primary 3 is connected in series -with the same source oi electrical energy, in such a manner that the current`through this primary coil is nia-de to flow in the opposite direction io the previously described current in the primary 2.

An arc light 7 is introduced in series in the primary 3, and the current flowing through this primary in series with the arc light being a continuous one, gener'ai-es an unyaried magnetic ield which, owing to its steailiness, neutralizes the variations of th'e magnetic field of .the primary 2 which are caused by the interrupter- G; and consequently no discharge takes place .the ciment in the circuit il, which is in series with thel arc light, `is effected by means oi a telephone transmitter 9 which is connected through batteries 10 to an This magnet is energized by the impulses created by the voice aci-ing through the dis.- l'ilnngin of the transmitter, and the magnet is placed in .close proximity to the arc light. The lines oi iorce thus generated through the magnet influence the'arc so that the current flowing through the circuit 3 andthe arc. are varied in unison with the variations induced through the transmitter and its connections. The primary 3, which is in series with the'arc light, is now The secondary coil is connected inthe usual A 1. In apparatus f'r transmitting sonorous vlbretlons,' primary coils, a secondary coll with Vconnected spark gap device. a source of electrical enecgy with which the primaries are connected, and menus whereby the passing electricsl currents are independently varied. p
