PASSENGER-DRIVER TELEPHONE SIGNAL SYSTEM FOR VEHICLES.

Specification of Letters Patent.

Application filed January 27, 1910. Serial No. 540,409.

T all whom it may concern) Be it known that I, HERMAN G. PAPE, a

signaling apparatus for closed body vehi-.

, cles such as landaus, landaulettes, limousines, victorias, town cars, cabs, taxicabs, etc., whereby the occupant or passenger can signal to the driver or chauifeur in order to attract his attention and then convey a message telephonically in giving directions, asking information, etc, and whereby thea driver or chaufleur can respond by'speaking through a direct audible device such as a tube or sound-amplifying horn.

The invention has for one of its objects to provide an appliance of this character which is of extremely simple and inexpensive construction, thoroughly reliable and eflicient in use, and so arranged and designed as to be conveniently operated.

Another object of the invention is the provision of a speaking tube or equivalent device which passes through the body of the vehicle .at a point close to the driver whereby he can place his ear or mouth to it for reoeiving a message or conveying one through the tube, together with a sound-reproducing device which can be energized by a circuitinterrupter or vibrator for signaling, or by a telephone transmitter when t e occupant .desires to speak to the driver, the arrangement and combination of said instrumentalities being such that the sounds can be conveyed distinctly without any great efiort on the part of the occupant or passenger and without leaving the seat.

With these ob'ects in view and others, as will appear'as t e description proceeds, the invention comprises the various novel features of construction and arrangement of partsv which will be more fully described,

hereinafter andset forth with particularity in the claims appended hereto.

Similar reference characters are employed to designate corresponding parts throughout the views.

the closed-in body of an automobile or other vehicle for which the present signal and speaking system'is especially designed. At some suitable partof the body, where it is conveniently accessible to the chauffeur, is a speaking tube or direct sound conductor designated generally by B, which passes through the front wall of the body in such position that the outer end of the tube will be close to the ear of the driver; The device B is composed, in the present instance, of inner and outer tubular trumpet-shaped members 1 and QHthat are connected together by a coupling 3 passin through the front Wall 4 of the vehicle be y, the outer member B forming a combined ear trumpet and mouth piece for use by the chauffeur, while pants within the vehicle. The part 3 is a Y- coupling' into two branches of which the trumpets 1 and 2 fasten, while in the third branch, a sound-reproducing device, designated generally by C, is fitted. This device C is of any approved construction, such for instance as that disclosed in my prior Patent No. 800,677, and is intended to be used for giving out -a signal when the chaufleurs attention is to be directed, or to reproduce the f speech of the occupant in conveying, a mesv sage to the chauffeur, and the part 2 or outer horn of the direct sound conductor B serves Referring to t-he drawings, A designates as an amplifying means for the sound waves generated by the device 0. v

The sound-reproducing device G cons sts of a diaphragm 4 arranged in a suitable chambered casing 5 that has a nipplefi com nected with the Y-coupling 3, and this diaphragm is vibrated by an electro-magnet 7 which has an armature 8 connected with the diaphragm," the winding of the electro-magnet being connected with the binding posts 9 and'9 to which the wires 10 and 10 are respectively connected. An intermittent current can be passed through the electro-magnet of the sound reproducer so as to vibrate the diaphragm, which will set up a buzzing sound toserve as a signal for attracting the attention of the chauffeur, and by use of a telephone transmitter, an undulatory current of varying amplitudes will be .sent through the magnet to cause the diaphragm to respond and set up speech vibrations which will be transmitted to the chaufieur.

r Fig. 9 shows the various instrumentalities used in connection with the sound-reproducmg device and circuit connections. The wires 10 and 10 form the signal and telephone circuit connections, the current being derived from a battery or other suitable source. A transmitter 13 of any approved construction is connected by the wires 14 and 15 with the wire 10 and battery 11. These wires 14 and 15 are arranged as a cord conductor so that the transmitter can be conveniently manipulated and said transmitter, which may be of the watch case type, has a handle 16 through which the wires 14 and 15 pass to the usual coil in the transmitter.

The circuit through the transmitter is'n0r-' mally opened, and when the transmitter is to be used, the circuits must be closed, and

' for this purpose, a push button or equivalent device is arranged, preferably, on th'e handle, 16, so that the button can be pressed while gripping the transmitter handle. In the present instance, thepush button or circuit closer consists of a spring 17 fastened on the handle and connected with the wire 15 and provided with a contact pin 18 thatis 'adapted'to engage a. contact strip 19 fastened on the handle and connected with the coil of the transmitter. Thus, by pressing the spring 17, the contacts 18 and 19 are engaged so that current will flow through the transmitter, and upon vibrating the diaphragm of the transmitter by the voice directed against it, anundulatory current will be ducing device which will be audible a articulate speech to the chauffeur. Arranged in shunt relation to the transmitter is a vibrator or circuit interrupter 20 of any approved construction which has tion in the diaphragm of the. sound-reproone bindin post 21 connected by a wire 22 w ththe wire 10, and the other binding post 23 connected by a wire 24= to the side of the battery to which the wire 15 is con- I nected, the wire 24 being provided with a normally-openpush button'25. The circuit interrupter consists of'magnet coils 26 that button 25, current Wlll ture 27 the movement of which operate on an armature 27 that carries a spring contact 28, which contact normally engages a relatively fixed contact '29, and the coils 26 are connected, respectively, to the binding post 21 and spring contact 28,. while the contact 29 is connected by a wire 30 with the binding post 23. Bridging the contacts 28 and 29 is a condenser 31 connected by wires 32 and 33 with the said contacts, so as to prevent excessive sparking between the latter during the operation of the interrupter. Upon fressing the push iibw through the coils of the interrupter and attract the armawill cause the contact 28 to separate from the contact 29, thereby interrupting the current and deenergizing the magnet so that the armature' will return to normal position. and again'close the circuit by en aging the contact 28. withthe contact 29. n this manner, the circuit will be opened and closed in rapid succession by the interrupter so as to cause an intermittent current to flow through the sound-reproducing device C, and as a consequence, a buzzing sound will be emitted through the outer horn 2 for at tracting the attention of the chaufieur. By reference to Fig.1, it ,will be observed that the push button 25 is located within the closed body of the vehicle at a point conveniently within reach of the occupant, and the transmitter 13 is arranged ad acent the push bptton and is normally held in a pocket 34 or equivalent device so as to be og out of the way. v

' The battery 11 and interrupter 20 may be t installed at any convenient, oint on the vehicle, as under the seat, at t e. dashboard or other place found most desirable by the 5 formed bythe two horns 1. and 2vis always, 10

available for use by the chauffeur in order to speak to the occupant orto receive a. signal";

andmessage from the'latter-l The horn or trumpet 1 augments the sound of the chauffeurs voice so that the. occupant can readily .115 "hear what is being said. The sound-reproduced that causes a corresponding vibra producing device 4C is also located in proximity tothe chauffeur, andthe outer horn augments the. sound so that the signal or message from the insideoccupant can be,120

described, and is. highly'eflicient inpractice.v 1'30 While I have shown and. described the invention is applied to a closed body vehicle, it will be understood, of course, that itssphere of usefulness is not confined to that particular application and it is adaptwhich I now consider to he the best embodiment thereof, I desire to have it under-' stood that the apparatus shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.
