WIRELESS-TELEGRAPH SYSTEM To (Ll-Z whom it may concern:
Be it known that I, HENRY H. C. DUN- W'OODY, a citizen of the United States, residing at Washington, in the District of Colum- -bia, have invented certain new and useful I Improvements in -WireIess-Telegraph Systerns, of which the following is aspecihcation. My invention relates to wireless telegraph or signaling. systems," and has for its object more particularly to provide an improved wave res onsive or detecting device, and to these en s my invention Consists in a WELXQ nesponsive or detecting device of the eharacter substan'tiallyas specified, adapted to be arranged and o crating substantially inthe manner hereinater pointed out.
In the accompanying drawing,-Figure 1 is adiagram showing asignal receiving apparatus embracing the subject-matter of my invention; Fig. 2 is another diagram showing the circuits somewhat difl'erently arranged; Fig, 3 is a detail view showing one manner of utili nng my wave responsive device; and Fig. 4' is a transverse section of an electrolytic apparatus showing another way of using my wave res onsive device. The material whic I now describe is a crystalline material, "and comprises a concrete mass or body of what is generally termed magnetite either natural or artificial, and having the general formula of Fe This material'may be of any desired shape or size, and is generally used in the form of a concrete mass or body of crystals which may vary in size and. character. This wave responsive material can be connected in the circuit of a signal receiving apparatus-in many and venous ways, some of which are indicated in the annexed drawing, and I do not, therefore, limit myself to any particular mannerof usin the material, or any particular form thereo y In the drawing A represents an aerial receiving conductorfor Wave collector or antennae, which may be of any well known or desirable form, being shown for. convenience I as embodying whatis generally known as the vice W.
fan type of aerial receiver. This receiver or collector is connected to a conductor c having a ground terminal (1,, and interposed in this conductor is the wave responsive de- In Fig. 1 there isa branch circuit including a battery Bf. and conductors I), I), which are connected to coin'luctors a, c at opposite Specification of Letters Patent.

sides of the Wave responsive device W. This circuit includes a signal receiving device,
shown in the present case as in the form of an ordinary magneto telephone receiver, in practice this being usually embodied in the ordinary head telephone form for convenience.
In Fig. 2 I have illustrated an arrangement which I have found to be practically operative, in which there IS an aerial receiver or wave collector A, in which the antennae are connected by the conductors e, a to the vice W, there being no battery or other independentsource of electric current. I
The wave responsive device may be in -many and various forms, and in Fig. 3 I have indicated it in the form ol" a mass or body W of crystalline material in the lormv of magnetite, to which the ends of the wires or conductors .a, a are: secured in any suitable way, as by being twisted or bound tightly around. the ends of the body.
In Fig. 4 I have shown a vessel V cmitaining some electrolyte as mercury, or an acid, or an alkali electrolyte, and who wave responsive device W is preferably in the form of a pointed mass, and at one end is connected to the conductor (1-, the sn'iallcr or pointed end being innnerscd to a greater or less-extent in the electrolyte, and the other cmiduetor c is either connected to the vessel V, il" it is ol conducting material, or to a separate electrode or terminal (1. immersed in the electrolytic fluid.
I do not deem it nmwessary to describe other forms and ways ol" using the material for the purposes intended, as they will befappreciatcd by those skilled in the art.
It will be understood that in actual practiec, my new wave responsive device may be used in connection with tuning devices or other adjuncts conmionly known and used in IIO type.
advantage that it will not burn out or be destroyed When located near a sending station.
as the intense disturbances or waves produced ste sending station located in proxinn ity to my improved receiver, do not destroy or injure the same, as the case with many other responsive devices of the electrolytic I have found that What is ordinarily known as the loadstone, being a natural product, is well adapted for the purposes intended, and also the artificially prepared crystalline metej rial whether in the i'ornr of the Iril'erro-l tetra oxid, commonly called the magnetic oXid and having the formula Fed) or in the 5 form of t sesqui-oxid having the general i'orl mule F0 0 although so far as iny present tests are concerned I prefer to use the former.
What i claim is,-
l. A WZLVU responsive device Concrete mass or body of comprising a. magnetite. A wave responsive device comprising a concrete mass of crystalline magnetite.
3. A wave responsive device comprising a concrete mass of loadstone.
concrete crystalline mass of iron and oxygen. 5. A wave responsive device comprising a concrete crystalline mess of material expressed by the formula Fe O In testimony whereof I afiix my sign eture in presence of two witnesses.
