SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 757,030, dated April 12, 1904.

Application filed June 22, 1903. Serial No. 162,601. (No model.)

To all whom it may concern;

. Be it known that I, ERNEST A. FALLER, a citizen of the German Empire, residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Signaling-Apparatus, of which the following is a specification.

The present invention relates to improvements in apparatus for sending or transmitting signals by means of electricity.

It more particularly relates to signals capable of great variation such as, for instance,

numerical signals to be used in identifying telephone subscribers. It is,furthermore,a latentsignal transmittera'. a, a transmitter in which the act of the user in preparing the apparatus for the signal does not necessarily cause the immediate transmission of the signal so prepared, but leaves the actual transmission entirely independent of any act of the user beyond the simple preparation of the instrument for the signal act. Variable-signal or latent-signal transmitters are not new, and a great variety of such apparatus have been at various times invented and patented. hat is considered broadly new, however, is the herein-described system of cooperation between a central point provided with suitable apparatus for receiving and recording signals and the signaling-stations. The signal-transmitter ordinarily in use transmits a decimalsignal, each series or numeral-figure of which is variable at will. It is old to transmit series of impulses, one series following the other; but it is broadly new to transmit a set of two numerals at one operation or, in other words, to have the signal consist of groups or sets of numerals each comprising two or more numerals and the groups timely following each other. It will be seen that by thus transmitting two or more numerals at practically the same time the speed of transmission is doubled, trebled, &c.

Heretofore when sending signals consisting of groups timely following each other it has been the exclusive practice to make the proper sequence of recording dependent upon synchronism between the signaling apparatus and the recording-station. This arrangement has invariably necessitated delicate apparatus and has rarely been reliable.

In the present invention no synchronism need exist, and it is thought that a broadly new principle is employed to obtain distinct and separate records for each part of the signaltransmitter.

Step-by-step mechanism and variable-signal transmitters are old and well known and have been used in practically all of the automatic systems so far devised; but although used in the present invention they are brought to new and distinctly-different use, constituting an entire departure from all known systems of transmitting signals.

The system forming the subject-matter of the present invention employs, preferably, the ordinary circuits provided in a telephone system i. 0., two metallic conductors and an earth or ground return. It is assumed that the source of electrical energy for the operation of the signaling system is located at the recording-station and that no source of electrical energy is available or required at the sending apparatus, which is in keeping withmodern telephone practice. Concerning the paths for an electrical current in such a system it will be seen that there are three possible combinations of conductors available, and consequently three distinct and independently-operative though not necessarily altogether independent circuits. Two of these circuitsnamely, the two in which ground is used in combination with one of the metallic linesare employed to transmit the signals proper. One of the circuits above mentioned is in addition used to transmit a preliminary or starting impulse between the signaling instrument and the recording-station, which impulse causes certain changes in the said station tending toward the starting of the latent transmitter at the senders station. The third of the circuits above described serves to effect the restarting of the transmitter. Upon the transmitter being set in motion two circuits are utilized for the simultaneous transmission of part of the signal. An entirely different cir cuit, however, is thereupon established at the recording-station, whereby the signal-transmitter' is restarted and allowed to transmit another part of the signal. It is desirable that the same circuits over which the signal is transmitted should not be used to restart the sender, as if they were so used no variable interruption between groups of the signal would be possible without considerable loss of time. It is the recognition of this principle which forms the basis of the present invention, and it is considered that the solution offered in this application is not only the first, but the only possible one of the problem. It will further be seen that instead of using one of the circuits first described to initiate the signal operation the last-mentioned circuit could be used for the same purpose, as it differs in character from both signal-transmitting circuits; but in the system illustrated it is preferable to have the apparatus operate in the manner described.

The present application illustrates and describes an apparatus and method for transmitting and recording any one signal between 0000 and 9999; but it is evident that by the addition of more number-rings at the senders operation and more selectors at the recording-station or the dividing of the signals in group containing more than two elements the system is extensible, so as to embrace practically any number of combinations. In all these cases the restarting of the signal -transmitter between the sending of each group of signals would be effected in the same manner as the first restarting act.

To sum up, it will be seen thatthe employment of a distinct circuit for the restarting act and a circuit differing from the two circuits employed for actually transmitting the signal makes it possible to render continuous the principle of alternate actuation of the recording-station and the transmitting-station, so that there is no practical limit to the number of groups forming any particular signal.

In the accompanying drawings, forming part of the present invention, Figure l is a front View of the sending or signaling apparatus. Fig. 2 is a view from below with the casing removed. Fig. 3 is a front view similar to Fig. 1, but having part of the mechanism removed in order to show some of the'interior parts. Fig. 1 is a side elevation of the apparatus in the line A A of Fig. 1. Fig. 5 is a cross-section in the line B B of Fig. 1. Fig. 6 is a similar section in the line C O of Fig. 1. Fig. 7 is a perspective side view of a member ring provided with the characters of identification of a telephone subscriber. Fig. 8 is a perspective side View of the devices for sending the desired number of impulses. Fig. 9 and Fig. 10 are diagrammatic views of the circuits and parts of the sending and recording apparatus.

Referring to Figs. 1 to 6 of the drawings, 1 is a base-plate, made of wood or other similar material, to which there is securedaframe 2 for holding the several parts of the device. 3 is a rotatable shaft, upon which is keyed the device 4:, consisting of a number of disks insulated by suitable insulating-rings from the shaft 3, as well as from each other. 5 is a sleeve carried on the outer end of a shaft 6 and provided with a milled knob 7. Secured to the sleeve 5 is a part 8, having the form of partof a cup and is capable of rotation on the shaft 6. Secured to the shaft 6 is a sleeve 9, provided with a cam 10, against which cam 10 one of the sides of the part 8 is capable of acting. To the cam 10 is also secured one end of a helical spring 11, the other end of which is secured to the frame 2 of the device. In turning the knob 7, therefore, the part 8 will act against the cam 10 and Wind up the spring 11. To the sleeve 9 is also secured a ratchetwheel 12. Loosely mounted upon the same sleeve is a gear 13, carrying a pawl 14, cooperating with the ratchet 12. In mesh with the gear 13 is a lantern-pinion 15, secured to the shaft 3, and connected to the lantern-pinion is a gear 16, which is in mesh with the pinion 17 of an escapement device consisting of escapement-wheel 18 and a verge 19. The escapement-wheel 18 is provided with a pin 20, for a purpose hereinafter to be described. The shaft 3 carries also a disk 21, having holding-notches 22, and the outer end of the shaft 3 has secured thereto a rotating lever of insulated material 23, provided with a contactpin 24. In a plan with cam 10 there is secured to the frame of the device a doublearmed lever 25, one end of which is capable of being acted upon by the cam 10 and having a notch for receiving one side of the part 8. The other end of the double-armed lever 25 forms acontact-piece 26, for a purpose hereinafter to be described.

The disks 4 on shaft 3 are similar in form and are provided with a number of teeth 27 and diametrically opposite to the teeth with a cup-shaped rim 28. As will be seen in Fig. 8, two of the disks 1 are located with their teeth 27 in the same direction as the cupshaped rims 28 of the other two disks. As stated hereinbefore, the disks 1 are electrically insulated from the shaft 3, as well as from each other. Each of the disks is provided with ten teeth, with the exception of the thousands-disk, which has an additional eleventh tooth 29.

Secured to the frame 2 of the sending apparatus, but insulated therefrom, are a series of contact-springs 30, capable of making contact with the teeth 27, but not long enough to make contact with the rim 28. Surrounding the disks i a corresponding number of number-rings 31 are held in place by four peripheral bearings 32, so that these rings are capable of rotation without lateral displacement. The periphery of each ring is provided with the numerals from 0 to 9 and diametrically opposite with a corresponding number of indentations 33, acting against which are rollers 34, held by springs 35, secured to the frame of the apparatus for the purpose of fixing the position of any one of the rings 31. Each of the rings 31 is provided with a support for an interior contactspring 36, which is electrically connected to the ring and is capable of making contact with the rim 28 of the disks 4.

It will be understood that the frame of the sending apparatus is capable of carrying electric current to the springs 36. Adjacent to the insulated lever 23 of the device secured to one end of the shaft 3 there is an insulating-block 37, provided with a set of upper contact-springs 38 and a set of lower contactsprings 39. (Clearly shown in Figs. 2, 4, and 9 of the drawings.) Each set consists of two contact-springs capable to be bridged by the pin 24 of the lever 23.

An electromagnet 40 is located near the base 1 of the apparatus and its armature 41 secured to one end of adouble-armed lever 42, the other end of which lever consists of two

branch arms

43 and 44. The branch arm 44 is capable of acting against the pin 20 of the escapement-wheel 18, while the branch arm 43 is provided with an extension 45, capable of entering one of the notches 22 of the disk 21. The armature 41 is normally held away from the magnet 40 by means of a suitable spring.

Insulated block 37 is provided with a third set of contact-springs 46, located in the path of one end of the lever 25 and capable of being bridged by the contact-piece 26 of said lever 25. The lever 25 is held toward the contact-springs 46 by means of a suitable spring 47, (shown in Figs. 1 and 2 of the drawings,) but normally out of contact with the same.

Fig. 10 of the drawings illustrates one form of the signal-recording apparatus. This device is in part substantially the same as the selector described in page 7, line 118,0f United States Patent No. 686,892, granted November 19, 1901, to Ernest A. Faller. One selector is provided for each numeral of the signal to be sent, therefore four selectors for recording a signal between 0000 and 9999. Each selector consists of an electromagnet 48, 49, 50, and 51, each operating an

armature

52, 53, 54, and 55. Each armature-lever acts upon an escapement-wheel 56, 57, 58, and 59 and causes the rotation of contact-maker 64, 65, 66, and 67 until the same rest upon a segment of the segmental contact-ring 68, 69, 70, and 71, provided with suitable characters to indicate the signal to be recorded. A time-switch 72 73 and 74 75, controlled by a suitable motor and a pendulum 62 and 63, acting against an escapement-wheel and 61,causes the closing of a local circuit over the contact-pieces of the elements 73 and 75. The means "for establishing electrical connections between the magnets 48, 49, 50, and 51 of the selectors and the transmitting device at the senders station consist of a number of magnets and switches cooperating with a cam-disk 96, capable of rotation by means of a weight 97 or other means. The cam-disk 96 consists of two semicircles having different diameter, and therefore forming a shoulder 99 and a ridge 100. One side of the disk 96 carries a pin and the opposite side a pin 98. The shoulder 99 is adapted to act against the dogs 88 and 92 of the contact-makers 87 and 91, and the contact-springs 93 and 95 will be bridged in pairs by their respective contact-pieces on contact-makers 87 and 91, when the dogs 88 and 92 glide on the periphery of the cam having the larger diameter. They will return to their normal position under the pull of suitable springs when gliding off the ridge 100. The pin 98 of the cam-disk 96 acts against the dog of a contact-maker 89 and causes contact to be made with the contact-springs 94. This contact is of very short duration and closes a circuit between the magnet 40 of the sending apparatus and parts of the recordingstation,,for a purpose hereinafter to be described. Magnets 76, 77, and 84 cause the movement of armature-levers 78, 79, and 85 normally held away from the magnets by springs 82, 83, and 86. Each of the armature-levers is capable of being placed in the path of the pin 80 of the cam-disk 96, and may therefore prevent the rotation of said disk. A battery 101 may be brought in circuit, electrically connecting the different parts of the sending apparatus and the recording-station.

For a purpose hereinafter to be stated a single-pole switch may be placed in the conductor, connecting one of contact-plates 75 with the upper end of the battery 101.

Operation of the signaling apparatus: The first act of sending a signal consists in combining the numerals of the number-rings 31 to the figure forming the characteristic of the signal to be recorded at the receiving-station. This act constitutes properly the preestablishing of the signal, and it is done by turning by hand the number-rings 31 until the desired combination is shown between the arrows. (Illustrated in Fig. 1.) The selected figure in the present case is 2071. The rollers 34 have entered the indentations 33 corresponding to the selected numerals on the number rings 31 and the springs 36 have thereby been located so as to make contact of a predetermined length with the rim 28 of the disks 4, which constitute a controlling-contact. One of the springs 30, Figs. 6 and 9, is normally in contact with the eleventh tooth 29 of the thousand-disk. The contact-piece 26 is normally disconnected from the groundsprings 46 46, and the pin 24 normally bridges the contact-springs 38. The second operation in sending a signal is turning the knob 7 to its limit, whereby the spring 11 is wound up; but the mechanism is prevented from rotation by the extension 45 of the lever 42 entering one of the notches 22 of the disk 21 and the pin 20 resting against the end of the branch arm 44. Cam 10 on the shaft 6 remains in the wound-up position, whereas the knob 7 and the part 8 return to their normal position by the action of a suitable spring. As the cam 10 has now been removed from the end of the lever 25 the part 8 secured to the knob 7 may enter a suitable recess of that lever 25, and thereby be prevented from rotation. The spring 47 will cause the contact-piece 26 to bridge the ground-springs 46 46. The first electrical manifestation of the previous acts will be to establish a circuit as follows: from ground at the sending apparatus to ground springs 46, through the frame 2 of the sender to roller 34, ring 31, contact-spring 36, controlling-rim 28 of disk 4, eleventh tooth 29 of thousand-disk, over line (a to the magnet 7 6 of the recording-station, the frame of the recording apparatus to battery 101 and ground. The effect of completing this circuit will be to energize magnet 76 of the recording-station and to release the pin 80 of the cam-disk 96, held by the armature-lever of this magnet. The cam-disk 96 will rotate until the pin 80 rests against the end of the armature-lever 85, whereby the shoulder 99 acted against the dog 88 and closed the switch 87 93. In this moment another circuit is established from ground at the sending apparatus to groundsprings 46 46, now bridged by contact-piece 26, to upper contact-spring 38, now bridged by pin 24,through magnet 40 of the sending apparatus, over line 6 to the fourth contact of the contact device 93, now bridged contact-piece 87 to the third contact of the device 93, to the hundred-magnet 49 to battery 101 and ground. The effect of this circuit so completed is to energize the magnet 40 of the sending apparatus, withdraw the arm 44 from the pin 20 and the extension 45 from the notch 22 and allow the shaft 3, with all devices secured thereto, to rotate. The simultaneous energization of the magnet 49 at the recordingstation will cause the contact-lever to move one step for a purpose not forming part of this invention. The rotation of the shaft 3 causes the pin 24 of the insulated lever 23 to leave the upper contact-springs 38 and to break the circuit over ground just established. The eleventh tooth 29 of the thousand-disk has left the spring 30 and broken the circuit from ground through the frame of the sender, the line a, the magnet 76, the frame of the recording-station apparatus, the battery, and ground. During the first half of the revolution of the shaft 3 the impulses originating with the teeth 27 of the thousand and hundred disks will be sent simultaneously to the recording-station in the following way:

The impulses representing the thousand numeral are sent over a circuit as follows: from ground at the senders apparatus to the ground-springs 46 46, now bridged by the contact-piece 26, the frame of the sender to roller 34, contactspring 36 of the thousands number-ring, the controlling-ring 28, the teeth 27, sending in the example indicated three impulsesthat is, one for each of the numerals O, 1, and 2 the line a, the recording-station, the contact-piece 87 to first contact of the contact device 93, the magnet 48 of the thousand selector, to the battery 101 and ground at the recording-station.

The impulses representing the hundred-numeral pass oy er the following circuit: from ground at the senders apparatus to the groundsprings 46 46, now bridged by the contactpiece 26, the frame of the sender to the roller 34, in contact with the hundred number-ring 31, the contact-spring 36 of said ring, the controlling-rim 28, the teeth 27, sending in the example indicated one impulse, representing the numeral 0, over the line Z) to the fourthscontact of the contact device 93, the contactpiece 87, the third contact of the contact device 93, the magnet 49 of the hundred-selector to the battery 101 and the ground at the recording-station. By means of the pendulumcon'trolled time element 60 and 62 the contactbrush 72 will bridge the contacts 7 3 as soon as the impulses sent to the thousand and hundred selector are all recorded. This action will close a local circuit from the contacts 73 to the battery 101, through the magnet 84, and back to the contacts 73. The energization of the magnet 84 will cause the armature-lever 85 to be attracted and to release the pin 80, now held by it, so that the cam-disk 96 may resume its rotation until it is stopped again as soon as the pin 80 is held from further rotation by the lever 81 of the armature 79 of the magnet 77. Immediately before stopping at this point the pin 98 will have struck the dog 90 and for a short period of time caused the contacts 94 to be bridged in pairs by the contact-piece 89.

WVhen the circuit through the magnet 40 of the sender was broken, as previously described, the extension 45 of the lever 42 fell on the periphery of the disk 21 and entered the second notch 22 at the end of the first half of the revolution of the shaft 3 and the end of brush-arm 44 came again in the path of the pin 20 of the escapement-wheel 18, preventing its further rotation. The pin 24 of the rotating arm 23 comes now in contact with the lower springs 39. When now the contactmaker 89 of the recording station bridges the contacts 94 in pairs, a circuit is established as follows: from the lower end of the battery 101 at the receivers station to the upper contact on 94, to the next contact of the same device, over the line b to the sending apparatus, through the magnet 40 of the said apparatus to the lower contactsprings 39, now bridged by the pin 24, over the line a, back to the recording-station and to the lower contact on the device 941, to the second contact thereon, and to the upper end of battery 101. The effect of establishing this circuit is to again energize the magnet 40, but over an entirely dififerent circuit than that used for starting the sender for the first time, and to again release or restart the sender on its second half of the revolution. Near the end of the first half of the rotation of cam disk 96 and before the pin 80 was held by the lever 81 the cam 99 acted against the dog 92 and closed the contact device 95 by means of the contact-piece 91. At the same time the dog 88 of the contactpiece 87 slipped off the ridge 100 and the contact-piece 87 was brought out of contact with the contact device 93. After the first half of the revolution of the shaft 3 of the sending apparatus the teeth of the ten and unit disk 1 are now located near the springs 30, and the impulses originating with the tendisk are sent over the following circuit: from ground at the sending apparatus to the ground-springs 16 16, still bridged by the contact-piece 26, through the frame of the sending apparatus to the roller 34 and the number-ring 31 of the ten-sender, the spring 36, the controlling-rim 28, the teeth 27, sending eight impulses to represent the desired numeral 7, over the line a to the recording apparatus, to the third contact of the contact device 95, now bridged in pairs by the contactpiece 91, to the fourth contact of the same, to the magnet 50 of the ten-selector, to the upper end of the battery 101, through the battery, and to ground at the recordingstation.

The impulses originating with the unitsender travel over the followingcircuit: from ground at the sending apparatus to the ground-springs 416 16, still bridged by the contact-piece 26, through the frame of the sending apparatus to the roller 34 and the number-ring 81 of the unit-sender. Obviously by the impulses so sent the magnets 50 and 51 of the recording-station will be energized and cause the movement of the brushes 66 and 67 on the segments 70 and 71 to record the impulses received.

The pendulum-controlled time-switch between the ten and unit selector will close the switch 74: 7 5 when all impulses are received by the two selectors and a local circuit will have been established from one of the contact-plates 75 to the magnet 77 to the lower end of the battery 101, through the battery to the other contact-plate of the time-switch 75, both plates 75 being now bridged by the constant piece 7 4;. The effect of closing this local circuit is to energize the magnet 77, whereby its armature 79 is attracted, the lever 81 removed from the pin of the camdisk 96, now held by said lever 81, and the cam-disk is allowed to make its second halfrevolution until pin 80 is held again by the lever 78, and all parts and switches connected with or controlled by the cam-disk 96 are restored to their normal position.

The further use or application of the impulses received and recorded at the recording-station is no part of the present invention.

At the sending apparatus the shaft 3 has completed a full revolution and the shaft 6 has returned thereby to its initial position,

whereby the cam 10 presses again against the end of the lever 25 and removes the contactpiece 26 from the ground-spring. The shoulder of the lever 25 has been removed from the edge of the part 8 connected with the knob 7, and a new series of impulses may be preestablished at the sending apparatus by setting the number-rings and sending of the same initiated by turning the knob 7.

If it should be desired to interrupt the signal between groups, the switch 102 is left open. Only the first group of the signal will be received and recorded at the recording-station, and the remaining group will be held latent at the senders apparatus for any desired time and will only be transmitted to the recordingstation when the switch 102 is again closed by hand or suitable apparatus.
