COMBINED TELEGRAPH AND TELEPHONE INSTRUMENT.

Specification of Letters Patent.

Patented July ,5, 1918.

Application filed February 1. 1915. Serial No. 5,384.

To all whom it may concern:

Be it known that I, I'IERMAN G. Pni n,a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented a certain new and useful Combined Telegraph and Telephone Instrument, of which the followin is a specification.

. v y invention relates to a sound reproducing instrument designed for-use either as a telegraphic instrument or a telephone re- 'c'eiver, and is particularly adapted for use in place of the ordinary sounder such as is commonly used in the well known Morse telegraph system.

In accordance with my invention, an instrument which may outwardly resemble a telephone-instrument such as used by telephone operators, is adapted to be held against the ear and comprises means for reproducing telegraph signals which are heard as single taps or clicks substantially like the sounds produced by an ordinary Morse sounder. As the sounds are clearly audible only tothe person wearing the instrument, the noise of the usual sounder is eliminated. This feature renders the invention of special value for use in telegraph ofiices or rooms where a number of sounder-s are employed.

In such situations, the noise of a number of instruments in operation at the same time results inponfusion and renders it necessary for each operator to have a shield or sound director for his own instrument 1n order to distinguish it from the other instruments;

By the use of the present invention the noise and confusion is eliminated, and 'each operator hears his ownv soundcror receiver without distraction.

An object of the invention is to produce a therapeutic telegraphic ear sounder, one

which will produce exhilarating instead of.

aggravating and sense dulling waves.

A further feature of the invention is the provision of sound amplifying and directing means for use in combination the sounder and to which the sounder may be connected at will to permit the sounds to be heard at a distance. Thus, for example, in a railroad station where the ticket agent is also the telegraph operator, the sounder may be worn on his head while he 1s receiving the telegraphic messages, and when through, or at any time he may remove the tion, the sounder may comprise an elcctro-' magnct having a fixed continuous circuit or winding to be connected in the telegraph circuit-n1 the same manner as the standard Morse ticker or sounder, said magnet havingan armature suspended to vibrate in response to the electrical impulses set up in the magnet. A sound reproducing member, diaphragm, sounding piece oranvil. is located adjacent a striker connected to the armature, so that the movement of the armature produccd by an electrical impulse, causes the said striker to strike the diaphragm or anvil, resulting in a tap or click substantially like that produced by the ordinary Morse sounder. In order to prevent a continued vibration of the diaphragm, sounder, or anvil and consequent continuation or lengthening of the sound, an adjustable bufl'eris set against the diaphragm or anvil which permits only an instantaneous sound or vibration. Cork or other suitable material may be interposed between the said striker and the magnet armature to furthcraid in deadening any continued vibration of the magnet armature, and to secure an agreeable and not sharp or aggravating tick.

Suitable means may be provided, for adjusting said striker, to bring it in contact with the diaphragm and thereby convert the instrument into a telephone receiver capable be directed to any part of the room. The

sounder may be quickly attached or reco-pending application, chamber of my ear piece need only be made convex instead of concave, so as to constitute moved from the amplifying device, being held thereon by spring clips or other suitable means. d

It is of course, not necessary to provide a sound amplifying device as disclosed in my a typical trumpet bell similar in design to other support, it may be instantly. used at the will of the listener, in absolute privacy, through the application of a' form of ear tube thereto, like or similar to those shown in my Patent No. 7 89,87 6. Such tubes may,

ing device, sound transmitter, sounding disk, sound box or theglike, which maybe the am- .plifier as here shown in Fig. 4, or any other more suitable amplifier or sound carrier, or even a sound-proof box or housing over a standard -Morse type table ticker, without departing from the scope of my invention,

as will be-apparent by an examination of. the appended claims, Other features and vention. will appear hereinafter.

In the accompanying drawings Fig. lis

an elevation view of a sound reproducing instrument constructed in accordance w th the principles of my invention. I Fig. 2"is an end view, -the removable top or end 28 being removed. Fig. 3 is a sectional view. as in- I dicated by the line 3-3 of Fig. 1. Fig. i is" a. part sectional elevation of the sound amplifying and directing device with the receiving instrument or sounder attached thereto.

Fig. 5 is aview of the sounder and means for attaching it to the amplifier as viewed from the right hand side of Fig. 4%. Fig. 6 is an end View of the sounder with the ear piece removed.

The recelver or sounder comprises' a disk,

mounted'an electro-magnet comprising a coil 2 and 'a shell 3 which may have a screw threaded connection l in a wall or partition 5 of the mountingfsupport or casing 1.

" Binding posts 6 for-the ends of the magnet coil are threadedinto metaLplugs 7 provided with terminal openings 8 for split pins or other terminals of the line wires. A cap or ear piece 9 is removably attached to the casing 1 by means of an annular flange or projection 10 externally threaded to engage corresponding threads on the casing 1.

threaded ring or nut 11 secures in position a diaphragm 12 preferably of metal, the periphery of which is located between a shoulder 13 formed on the casing and the cited. The outerof course, be attached to any sound direct-,-

advantages of the in-.

are placed on opposite sides of the di a' phragm betweensaid shoulder and the ring 11. The pressure or. the gaskets 14: may be regulated byrotating the ring 11- to any desired position of adjustment.

The cap or earpiece 9 is adjustable toward and from the diaphragm providing a focus regulation and is held against accidental displacement from its adjusted position by means of springclip or tongue 15 secured as by a screw 16 to the cap! Said spring is adapted to seat in notches 17 arranged at intervals around the casing 1. Indexnumbers or other indicating characters 18 may be placedon the casing adjacent the notches 17 to indicate the po'sltion of adjustment, and enable the user after having once determined the most effective adjustment for any specific use, or best suited for his ear, to readily adjust the cap to such position .at any time without further experiment. To prevent the cap 9 from being accidentally entirely unscrewed. and disconnected from the casing 1 the latter is, provided with an annular shoulder 15 in the path'of the spring 15 which offers sufficient resistance to the removal of the cap to give warning when the cap is unscrewed beyondits normal range of adjustment.

The cap or car piece 9 has a central opening 19 and an inner curved-sound reflecting surface 20 which tendsto focus or'concentratethe sound waves at the center of the diaphragm from which point they are most effectively transmitted through the sound vconductingopening 19., The surface 20 is;

surrounded by an annular depression or enlargement 21 of the sound concentrating chamber or opening between the diaphragm and cap 9, which enlargement forms, a swell chamber or capacity chamber to divert oi relieye the pneumatic pressure set up, preventlng undue pressure on the ear drum of the operator, preventing dinand fatigue and indistinct or mufiied sounds. Kerfs 19,- such as disclosed in my Patent No. 800,675, )ct.

structure creasing 1 in which or. to whi h i 8', 1905, may be formed in the outer face of v the cap and extend radially outward from the opening 19.- These kerfs form outlets to relieve the pressure in the sound concentrat.

ing chamber, and aid in producing. clear-and on the ear drum.

The electro-magnet is provided With an.

armature 22 suspended to vibrate in response P to electrical impulses in the electro-magnet.

The means for suspending the armature, comprises a sleeve or hollow extension piece A. 23 connected to a supporting spider 2a which,

as shown in Fig. 2, comprises radial arms integral with inner and outer ring 25 and 26.- The sleeve extends through a central openlng out of direct contact with the spider but produced by the common by the cement 27. The lower end of the rod may also be connected by cement 32- to a spider which may be of the same construction as" the upper spider 24. The spider 33 is held in position between washers 3a hav-.

ing a screw threaded connection with the casing 1. The material 27'and 32 uniting the sleeve 23, red 31 and upper lower spiders, may be the same as that set forth in my co pending application Serial No. 874,23 and used therein for uniting the main diaphragm and electrode. Said spiders form an elastic support permitting the armature to move freely in response to electrical impulses and at the same time permitting adjustment of the hammer or striker 29 toward and fromthe diaphragm 12. Such adjustment may be efi'ected by a plug threaded into the top piece 28 and carrying a block 86 of felt or other soft elastic material which bears against the upper end of the rod 31 or sleeve 23. By screwing down the plug 35 the striker 29 is brought closer to the diaphragm and by screwing the plug outward, the striker and connected parts are lifted upward or away from the diaphragm by the resilient supportin spiders 24, 33. Blocks 37 of felt or the like bear against the spider 33 and together with the material 36 tend to prevent any continued vibration of the stri er 29 so that when the magnetis energized the striker will give a single sharp blow to the diaphragm.

To prevent a continued or lengthened vibration of the diaphragm, a sound deadener or buffer device is provided to bear against the diaphragm. device may be widely varied, and as herein shown comprises a disk. 39 of felt or the like, eccentrically mounted on the inner end of a light' spring rod 40 extending through the casing 1 and provided externally on the casing with a thumb piece for. rotating the rod or adjusting it longitudinally, and thereby adjusting the pressure and position of the buffer 39 on the diaphragm. A set screw 40'' locks the bufl'er'in adjusted position. It will'be noted that with the buffer against the diaphragm the entire construction is designed and adapted for producing sharp, short sounds or clicks, substantially like those Morse sounder, and in marked contrast to the humming The specific form of such and poorly defined soundsproduced in an ordinary lLOlUPllOllO receiver by Morse code signals.

When the armature is operated by a magnetic impulse, the tapper produces a tap or sound on the diaphragm, and depresses and holds the same in a depressed state, until the circuit is opened or the current [low through the magnet coil shut off, when the armature and diaphragm return quickly to normal position, which action causes the diaphragm to render a second sound identical to that caused by said tap, the product ion of the two sounds in this manner being typical of and essential for producing the hlorse type of signals.

By screwing down the plug 35 until the striker 29 engages and bears with a slight tension against the diaphragm, the instrument may serve as the telephone receiver as the diaphragm will then follow the move ments of the striker and is thus capable of reproducing articulate sounds. Its action as a telephone receiver may also be improved by adjusting the buffer 39, away from the diaphragm.

The instrument is provided with a bail 41 and a spring clip or head piece 1: enabling tllv instrument to be attached to the ear of the operator in a well known manner. The adjusting plug or thumb screw 35 is held against accidental rotation from any adjusted position by a spring clip 36 secured thereto and adapted to seat in any one of a series of radial notches 37.

In Fig. d is shown a sound amplifying and directing device 43 to which the sounder may be attached for the purpose of magnr fying the sounds so that they may be distinctly heard at a distance from the sounder. Said device may comprise an outer hell or dome having a rear opening l5 at which is connected a funnel or horn 16 through which the sound waves from the diaphragm 12 are directed and amplified, said sounds striking a deflecting surface 47 formed by an inner hell or dome 48. The sound reflected from the surface 47 is thrown rearvardly and againv amplified and reflected on the surface 4-9 of the outer bell 44 and from thence again amplified as it is directed outwardly through the open mouth of the bell 44. The inner bell 48 is secured to the outer hell by brackets 50 and 51, and tothe funucl lti by brackets 52. These brackets serve the double function of rigidly uniting the parts and also preventing the bells or funnel from ringing. The sounder is removably attached to the amplifier by any suitable means such as spring clips 53 secured to the bell ll and having their free ends curved to engage a shoulder S t on the sounder and hold the latter clamped against the bell it.

In order that the bell 44 may be pointed in any direction for directing the sound, the

- aid 55 and amplif ing device carried there-- device is 'mounted'on a standard 55 rotatably supported-on a stationary base 56 whichmay be attached by screws 57 to a table or other support 58. In order to hold the standard against accidental rotation from any position of adjustment, a spring actuated hold;

ing pin 59 is mounted in a disk or support 60 fixed to the standard 55, said pin adapted to engage any one of a series of notches 6 1 placed at suitable intervals in thebase plate 56. By withdrawing the pin 59, the standby maybe rotate to point in any desired direction. i

Thesound directing device may also be tilted to any desired angle, andfor'this purpose is attached to the standard 55 by means of'a bracket-62 fixed to the bell 4:4, and a pivot screw 63. The lower end of the bracket '62 is in the form of a segmental'rack 64:, held in any desired position of adjustment about the pivot 68 by a detent 65. The latter is held in; engagement with the rack by. a spring 66 and may be withdrawn from'the rack by means of a adjustment. 7 Various modifications may be resorted to finger piece 67 to permit without departing from the spirit and scope of my invention.
