TELEPHONIC RELAY.
Specification of Letters Patent.
Patented Jan. 23, 1917.
Application filed July 11, 1916. Serial No. 108,?01.I
To all 'whom it may concern:
Be it known that I, FRANK E. SUMMEns, a I`itizen of the United States, residing at Memphis, in the county of Scotland and State of Miouri, have invented certain useful Improvements in Telephonie Relays, of which Lhe following is a specification, ref-ei`- ence bang had therein to the accompanying drawing.
This invention relates to improvements in telephonie relays, one object of the invention bein!)l the provision of an amplifying relay of the microphonic type in. which a diaphragm is provided and is disposed -in ceoperative relation with tWo oppositely disposed electro-magnets, the cores of which are disposed upon opposite sides of the diaphra-gm and such cores adjacent the diaphragm being like poles.
A further object of this invention is the provision of a device of this character which 1s readily connected in atelephone circuit to amplify the sound Waves transmitted to the'receiving instrument, there being provided means to tune the diaphragm to the different vibrations per second, so thatsu'ch rso diaphragm will respond and be sensitive to such vibrations.
A still further object of this invention is the provision of a telephone relay which l employs a polarized receiver having a tuned 2 1s a sectional vieu7 diaphragm which makes the present device exceedingly sensitive to Weak currents.
Withthe foregoing and other objects in View and which will appear 'as the description proceeds, the present invention resides in the novel arrangement and combination of parts hereinafter set forth and particu.- larly claimed, it being o ssible to ina-ke many changes in the prcise embodiment Without departing from the spirit 0f the invention. j i
In the accompanying drawings :-Fi'gure 1 is a side elevation df the complete relay with the telephone circuit in diagram. Fig. through the diaphragm and the adjacent portions-thereto, the miorophonic device being shown in section. vFig-3 is a side-elevation of the device taken 'from theright as shown in Fig. 2. Fig. 4 1s a view taken from the opposite side thereof. j
Referring tothe drawings, the' numeral 5 designates the base of the present apparatus which hassupported thereon the' two rightangled brackets 6 and I carrying respon tively the electro-magnets 8 and 9, the north poles ot' which are projected toward each other. Also mounted upon the base of each of the brackets 6 and 7 are the' permanent bar magnets l0 and l1 respectively which are adjustable longitudinally through the instrumentality of the screw and bracket supporting device 12. It will be noted that the north poles thereof are disposed adjacent to the respective brackets 6 and 7 and that therefore said magnets vvillV polarize the respective cores Sand 9, the purpose of which will presently appear.
The winding of the clectro-magnet 8 opposite to the Winding ol: the electro-magnet 9, and the core of such electro-magnets is preferably soft iron or steel. ryhus, the inner poles, here shown as. the north poles of the respective coils 8 and 9, will have' a permanent magnetic ellect adjacent the center and upon'both sides ot the diaphragm 13, and it is thus evident that an alternating current will tend to inagnetize one core of one of the electro-magnets and polarize the other core of the remaining electro-magnet upon the opposite side of the diaphragm, as the lion' of the current, being alternating, will first flow in one. direction and then in the other. Thus, one core at one side of the diaphragm `1will become magnetized, while upon the opposite side it will become polarized, and vice versa. The strength ofA the polarization or permanent magnetic field upon the respective cores of the electro-mag nets 8 and 9 is adjusted through the screw connection 12. By this construction, the
present device can be used as a. polarized receiver for telegraphic messages, but Where the same is used as a telephonie relay, the core of -the electrofmagnet 9 isconnected in a sleeve or tube l4of insulating material, anddisposed in said tubeare the particles 15 which with the metal disk. 16 attached to the diaphragm 13 and the metal disk 17 at the opposite side of the particles 15, form a microphone.
The adjusting screw 18 is mounted in the core 'of the electro-magnet 9 and is adjustable to vary-the compressive effect of the u particles 15 between the disks 16 and 17.
With this arrangement, it is apparent that `any vibrating of the diaphragm 13 under the iniuence of the alternating or vibrating currents in the transmittin.
presently appear, varies t e resistance of circuit, as will the conducting particlesd` so that the ourrent -from the battery 19 will be varied and influence in a similar manner the induction coil i2() and consequently the received niessagc at the receiver 21.
As many of these amplifying devices may be used as are i'iccessary, the same being connected in series so that each amplifier will increase the intensity of the incoming signal.
ln order to assist in producing a better result. l employ a rod 22 having one end 255 connected to the center oi the diaphragm 13, the aj'ieiture 2l. (herr-ol' surrounding the pin 25 carried by the diaphragm support 'Zl and having thereon the adjustable spring Q7 `lor providing an adjustable Jr'ulc'ium Jfor the rod Adjustably mounted upon the upper free end oi' the rod 22 is au adjustable weight 25', thus providing a resilient connection for the fulcruin of the rod or lever and having means that will vary the vibrations thereof as to nunibers and length.
n connecting the present apparatus` for use, the transmitter :ii is connectedV in cir Cuit with the battery 2o and the induction coil tlf), one conductor El() being connected M the binding post lil. while the core ot the -electi'o-niagi'iet FS is also connected to the binding posiv 3l. tlie.oj'iposite end of said core being connected to the binding post 3Q.
The conductor Bil is led from the, binding post Bi! to the binding post 34, while such binding post is connected to the inner end of the winding of the coil 9. while the binding post 35 is connected io the outer end of such winding, a conductor 26 connecting said l'iinding post lo the induction coil 29. .v
The binf'ling post 3T has the conductor 38 connected thereto, has the conductor 40 connected thereto, said conductors and l() being connected to the induction coil 2.0 and the battery 19 in the receiving portion of the circuit.
It is also apparent with this arrangenn-nt of appa atus that either a polarized tuned receiver or a polarized tuned transmitter may he used in conjunction therewith, and that when properly installed, the received .vibrations or alterations will be amplified or magnified so that atransmitter with eX- ceedingly weak currents possible.
lt is to be understood that in addition to the use of conducting particles there may be employed two loose resilient contacts of conducting material, ,such as two pieces of platinum, one piece being secured rigidly to the diaphragm and the other jiiece secured i n a resilient manner to the end of the ad- ]isting screw 12 as may be optional with the manufacturer or user of. the device.
