VINCENT C. DE YBARRONDO, OF LOS ANGELES, CALIFORNIA.

WIRELESS-TELEGRAPH SYSTEM.

To (LIZ whom it may concern:

lie it known that I, Vixcex'r C. DE Ynaunoxno,citizenof the llnited States, residing at Los Angeles, in the county of Los Angeles and State oi California, have invented certain new and useful Improvements in Wireless-'lelegraph Hystei11s.ot' which the following s a specification. reference being had therein to th accompanyingdrawing.

This invention relates to improvements in wireless telegraph syste1ns.and more particularly to the portable type.

It has for one'ot' its objects the provision of a central switch board equipped with suitable wiring in position to be readily connected with the aerial and sounding apparatus. 1

Another object. is to provide a swit h whereby the entire system may be cut out when desired.

further object is to provide a novel 'l'orin of wiring for the switch board.

A still further object is tt) construct the h thttlll whereby two a'erials may be used to dispcn-e with grounding the system.

With these. and other objects. in view, the preferred embodiment of my invention resides in that construction and arrangement.

ol. parts hereinafter described. illustrated in the accompanynig drawnigs. and embraced within the scope of the appended claims.

In said.-drawings:--I igure l is a plan view of the system. big. of two aerials connected to the coherer when the ground is dispensed with. Fig. 3 is a similar view with one aerial and the system grounded. Fig. -lis a bottom plan view of the switch board. Fig. 5 is a top plan view of the same. Fig. (3 is aside elevation of the switch hoard. Fig. 7 is'a similar view of the batten for the wiring. Fig. 8 is a. fragmentary vertical section of the switch board. Fig. 5) is a side elevation of one' end of the aerial. and F g. 10 is a. front elevation of one ol the aerial wire stays.

Similar nunicralsbt' reference are employed to designate corresponding parts throughout. i

In carrying out the. invention I provide what. will subsequently be termed a central switch hoard. This member is provided with suitable wiring which may be readily connected with ti 2 aerial through the coheizer. and is further equipped with connections for the local circuit consisting of a desired number otlmtteries. a relay, sounder Specification of Letters Patent.

and decoherer, and is still further provided with a switch, connecting one pole of the battery with a similar pole of the coherer, and by means of which the system may at any time be rendered inactive.

The switch board consists of a middle section (1), see Fig. 1, preferably of wood or other suitable insulating material, having a plurality of vertical openings, and is provided on its opposite faces with a number of grooves which terminate-in the said openings, the disposition of the grooves being such that by a t tive net work is formed on the opposite faces of the board. The major portions of the openings are arranged parallel with the sides a1 d ends of the middle section, and in each of these openings is fitted a machine screw (2). the threaded shank of which extends upwardly through the opening and the top section (3 The latter is preferably of the same material as the middle section and of a size to cover the upper face of the latter, as shown in Figs. 1. 5 and 8. To the thread ed terminal of each screw projecting beyond the upper section (3) a binding post (l) is secured. By referring now to Fig. 1 it. will be seen that the opposite terminals of the coherer (4:) are connected through the wiring (5) and ((3) to two of the binding posts (4) on one side of the board. and to the other two binding posts on the saute side of the board the decoherer (T; is connected by the wires (8) and (9). )u the opposite side of the board similar connection is'es'tablished with the binding posts. the wires (10) and (11) being connected to the coil end of a relay (12), the armature. end of which is connected to the other two binding posts on the same side of the board by the wires (13) and (14). Two binding posts are at one end of the boardywhich are connected to the poles of a sounder (15) by the wires (l6) and (17). 'hile atthe opposite end the board is provided with a pair of binding posts which are connected by the wires (15 and (19) to theopposite poles of a. battery (20). connection between the positive wires leading front the battery is established by a. wire (2t) the terminals of which are cared to the positive binding and contactpost (22) of a switch lever (23), the pivotal point of whiclris connected to the positive wire of the battery by a wire {24). The wire (21) runs in a diagonally disposed groove onthe lower face of the. middle secystcm of erosslng a conipara- Jun the wire disposed in a diagonal groove on the lower face of themiddle section sub-.

stantially parallel with the wire (21).

Connection is established with the opp0 site pole of the battery and the other binding post of the wire leading on thecoil side of the relay by the wire (26), which crosses the positive connection (24.) between the binding post and 'pivotal end of the lever (23), in the following manner. Suitable openings are formed in the central section on either side of the groove in which the wire (2st) is disposed, so that by inserting one end of the wire through one of these openings and then leading the same over the upper face of the central section and thence downwardly through the opposite opening, the cross is effectively made without the wires touching. A terminal on the opposite side of the relay is connected in the usual manner to the negative post of battery wire (18) by a wire 27 which crosses .the connections (21) and (25) between the coherer and coil side of the relay and battery-in the manner described .for the connection 26.

lonnection is established with the sounder wires (16) and (17), the other terminal on the armature side of the relay, and the decoherer by the wires (28) and (29) which cross the

connections

21 and 25 similar to the connection 26. The circuit is completed by the connection 30 between'the positive terminals of the coherer and decoherer. Thus it will be seen when the switch is closed, and a wave enters on the aerial (31), a portion of which passes into the earth by the ground wire (32), the cohcrer will be excited in the usual manner causing the local circuit'to close and the armature of the relay to be attracted, which transmits the current to the sounder and decoherer. When the latter vibrates, .e filings of the coherer separate in the usual manner and the circuit is opened. It can be seen by the use of two aerials the ground wire (32) may be dispensed with, and it is to be further observed that any form of sounder or pro duccr, such as a register, may be substituted for the sounder (15).

With this device the problem of portable wireless outfits will be greatly simplified, since it can be readily seen that the connections for the various lements are always in position. A batten (33), similar to the top section (3) is designed to be secured over the lower face of the middle section (1) whereby greater protection is given the wiring of the switch board.

Having thus described my invention what I claim as new is 1. In a portable wireless telegraph system, a central switch board formed of superimposed sections one of the same being provided with oppositely extending oblique the circuit between the cohcrer and locat receiving circuit, and a switch on said board to open and close the circuit of said connections.

3. In a wireless telegraph system, a central switch board, consisting of a middle section having grooves on its opposite faces forming seats for the wires, a balten covering the grooves on one face of said board, and a section provided with binding posts and a switch on the opposite face of said 7 board.

4. In a wirelesstelegraph system, a central switch board .:omprising a middle section having grooves on its opposite faces and vertical openings whereby a wire disposed in one of said grooves may cross the wire in the adjacent groove by passing through the said vertical openings, :1 top and bottom covering for said middle section and a swilcll on said top adapted to open and close the circuit of said board. I

5. In a portable wireless ltflugl'illlll system, a coherer, a relay, a sounder, a local battery, and a central switch board formed of sections one of the same being provided with grooves on its opposite face forming seats for the connections to open and close the circuit to said coherer, relay, sounder and local battery.

In testimony whereof I hereunto allix my signature in presence of two witnesses.
