UNIVERSAL RADIO AND DIRECT-SERVICE SYSTEM.
Application filed September 2, 1925. Serial No. 54,059.
This invention relates to a line delivery, signal service system for energizing remote loud-speakers, head-sets and, similar signal instruments.
The invention has for an object to provide a system whereby radio broadcasted entertainment and other features, such as various news items, special and important Government warnings, notices and reports, and other subject matter may be received at a central station and by it simultaneously sent over line apparatus to subscribers of a combined system having means adapted only for the receiving of signals and without return capacity. 1
An object 1S also to rovide for the distribution, to the line subscribers of the system, of all desired programs and information which may be collected, by the central station, from universal incoming telegraph and telephone line systems.
An object is to provide for the direct delivery of .matter which is not received from outside sources, but is originated at it.
It is an object to provide a system capable of pickin up or receiving local and far distant bro casting stations so that any desired or the best entertaining program on the air can be carefully, clearly and efliciently taken up by the receiving central station of this system, by expert operators using the highest ca acity and quality intrunk wires 9 which have numerous branches struments, and by t is station sent, over wire apparatus, to subscribers" loud-speak ers, head-sets and other receivers; the purpose being to eliminate local detecting and amplifying equipment, and yet give perfectly tuned reception.
And an object is to. provide a subscribers key-lock controlled jack outlet and jack key-plug combination.
Therefore, an object is to provide a universal radio and direct wire line delivery service, which has but one receiving medium, or rad1o detector, to deliver, by line wire, to key-lock controlled'outlet to which speaking receivers are connectible by proper key,
plugs only, therefore enabling large and remote distribution to numerous individual subscribers receivers having but one common source of intake radio energy.
A great advantage of this is the elimination of individual and troublesome tuning, the initial cost and the upkeep expense of private sets, the reduction of fire hazard from and avoid the need of house aerials, which are generally so unsightly.
Further objects and advantages will be made perceivable in the ensuing specification of an embodiment of the invention as exhibited in the related drawings; it being obvious and understood that this exposition switc In the present disclosure is shown a broadcast wave receiving aerial 2 leading into a suitable detecting and amplii'iyin set 3 with outlet lines 4 to a pair of xe terminals 5 engageable by a suitable switch S, which can be thrown over, to the circuit 6 of microphone transmitter T.
Terminals 7 of incoming telephone systems 8 are provided to be engaged by the switch S for sending purposes only to the present distributing system.
From the switch S run subscribers service,
10, to outlets, one or more of which may be located in rooms, halls or oflices of the various subscribers homes or institutions, such, for instance, as laces of amusement, dwellings, eating an drinking establishments, hospitals, etc.
Thus a community may be wired with the ap aratus above described and as new buildings are erected the service lines andwhen the cylinder is unlocked and turned the circuit to lines 10 is completed.
It is understood that a suitable number of outlets 0 may be placed in various rooms of a home or other building to allow use of a number of loud speakers at one time in the home, or permit carrying one loud speaker from room to room when so desired.
The central station is shown as having a telegraphic receiving set 12, as a source of information which can be translated and then transmitted by line to the service subscribers.
The station is equipped with a test speaker 15 to determine the quality of subscribers reception.
What is claimed is':
In a radio and tele hone system, a line outlet device having me terminals, 2) key lock including contacts coordinate to the terminals, and a key-plug having conduct-- ing leads cooperating with the contacts to close a telephone receiver circuit. EDWARD MCLARTY, SR.
