] Application filed March 16, 1909. Serial No. 8,869. (No model.)

To all whom, it may concern:

Be it known that I, HENRY GUY OARLETON, a citizen of the United States, residing at New York, county of New York, and State of New York, having invented certain new and useful Improvements Electric Signaling Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in electric signaling devices.

It is'one object of the invention to produce an improved electric signaling device which will be compact and efficient and which will be capacitated to transmit a large number of varying signals.

A further object of invention is to produce an electric signaling device which will be capacitated to transmit a large number of varying signals and to combine with such device a recording apparatus by which the transmitted signals will be recorded.

With these and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

v In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same parts, Figure 1 is a front elevation of a form of electric signaling device embodying the invention. Fig. 2 is a'plan view of the construction shown in Fig. 1. Fig. 3 is avertical sectional elevation on the line 3 3 of Fig. 2 and looking in the direction of the arrow in said figure. Fig. 4 is a sectional plan view on the line 4 4 of Fig. 3. Fig. 5 is a side view, partly in section. Fig. 6 is an elevation of the spring-motor employed. Fig. 7 is a view illustrating a set of circuits which may be employed with the apparatus.

Referring to Fig. 1,which illustrates one embodiment of the invention, 1 indicates a base of any suitable form or construction and composed of any suitable material. The base 1 is or may be provided with suitable binding-screws 2, '3, and 4: and has rising therefrom a support 5, which is or may be a brass plate. The support 5 carries a plurality of circuit-terminals. In the preferred form of the construction two plates 6 7 are used, said plates being formed of any suitable conducting material and being insulated from the support 5 when the same is made of conducting materialas, for instance, brassby means of suitablewashers 8. The plates 6 and 7 may be of any suitable configuration. In the form of the device shown they are are shape, and each of the plates is provided in the form of the construction shown with two sets of circuit-closing terminals, the sets of terminals on the plate 6 being marked 9 and 10, respectively, and the sets on the plate 7 being marked 11 and 12, respectively.

Cooperating with the plates 6 and 7 is a carrier 13, and the construction is arranged to provide a relative movement between the plates and terminals and the carrier. In the preferred form of the construction this is accomplished by making the carrier a rotating carrier and to this end is mounted on a shaft 14, which is journaled in the support 5. When, as in the preferred construction, two terminal plates are employed, the carrier will be provided with two contacts or circuit-clos ers 15 16, which cooperate with the terminals, said contacts being shown as made of spring metal. Each of these contacts is mounted on a block of insulating material, these blocks being marked 17 and 18, respectively, and being secured to the carrierin anysuitable manner. In the preferred form of the construction the carrier will be included in two circuits, one of said circuits including the plate 6 and one of the contacts and the other circuit including the plate 7 and the other contact. A circuit-controlling device will preferably be located between each of the said 99 contacts 15 16 and the carrier. While these circuit-controlling devices may be varied in form, in the construction shown that endof the carrier which carries the contact 15 is provided with a short vertical shaft or stud 19, said shaft supporting a tumbler-block 20, which is secured to the shaft by means of a screw 20 or in any other suitable manner. The shaft 19 also carries a finger 21, said finger cooperating with another finger 22,mounted on the insulating-block 17, said finger 22 being connected to the contact 15'by means of a short wire 23 or in any other suitable manner.

manner. Similarly that end of the carrier which carries the contact 16 is provided with a short vertical shaft 24, said shaft having secured to its end by a screw 25 or in any other suitable manner a tumbler-block 26. This shaft 24 carries a finger 27, which cooperates with a finger 28, secured to the block 18, said finger being connected to the contact 16 by a short wire 29. It is apparent that by throwing the tumbler-blocks 20 and 26 in one direction or the other the fingers 21 and 27 will be rocked into and out of contact with the fingers 22 and 28. It is apparent, furthermore, that when the fingers 21 and 22 are in contact and the contact touches any one of the circuit-terminals on either of the plates a circuit will be closed from the plate through the contact 15, the wire 23, the finger 22, the finger 21, and the shaft to the carrier, and similarly when the contact 16 touches any of the terminals on either of the plates and the finger 27 is in contact with the finger 28 a circuit will be made from the plate 7 through the contact 16, the wire 29, the finger 28, the finger 27, and the shaft 24 to the carrier. If, however, either the finger 27 or 21 is moved away from the finger 28 or 22, no circuit will be made, although the contacts 15 16 touch the terminals of the two plates.

In the construction shown, as has been said, the carrier is a rotating one, and as the contacts 15 16 successively touch the circuit-terminals on the plates 6 and 7 a circuit will be made and broken, provided the fingers 21, 22, 27, and 28 of the circuit-controllers are in proper position, and a series of impulses will thus be sent over the line.

Any suitable motor may be employed for the purpose of rotating the carrier. Preferably, however, a spring-motor will be employed, and the construction will preferably be that shown in Fig. 6. Referring to this figure, the shaft 14 is provided with a pinion 30, said pinion being loose on the shaft and having connected to it a notched hub 31. This notched hub 31 is engaged by a pawl 32, said pawl being mounted on a gear 33 and being held to its duty by means of a spring 34. The gear 33 is fast on the shaft 14, which extends through and finds a bearingin a back plate 35, said back plate being secured to the support 5 by means of screws or in any other suitable manner. In order that the rotation of the gear 33 may be suitably controlled, it meshes with a pinion 37, mounted on a shaft 38, said shaft finding its hearings in the plates 5 and 35. This shaft 38 carries an ordinary escapement-wheel 39, said wheel operating in connection with an ordinary escapement 40, mounted on a stud 41, said escapement being provided with the usual fan 42, which is weighted on one side, as shown at 43, so as to cause the escapement to stop in proper position. The pinion is the driving-pinion of the shaft 14 and may be placed under spring tension and driven in any suitable In the construction shown the pinion is in mesh with a segment 44, which is mounted on a shaft 45, said shaft in the construction shown finding its bearings in the plates 5 and and extending through the latter and being provided with a handle 46. The shaft is also provided with an arm 47, said arm having connected thereto a spring 48, the other end of thespring being con nected to a pin 49 on the plate 5.

A suitable releasing device is provided to control the action of the escapement and permit the parts of the motor to be driven by its power-spring. This releasing device will be electrically controlled, and in the form of the construction shown it consists of a releasinglever 50, said lever being pivoted at 51 on the plate 5. The lever forms the armature for a magnet 52, which is secured to the plate 35 in any suitable manner, as by a bracket 53. The lower end of the lever 50 is provided with a pivoted latch 54, said latch being in the path of the arm 47 and being arranged to be struck thereby as the said arm is thrown upward by the operation of the handle 46. An inspection of Fig. 6 will show that as the arm 47 moves upward and strikes the end of the latch 54 the lever 50 will be turned on its pivot 51 and its upper end will be caused to passunder the escapement-fan 42, and the lever will therefore act as a lock to prevent any movement of the escapement, and thus any movement of the spring-motor under the operation of its spring is prevented. At the same time downward movement of the handle 46 places the spring 48 under tension and rotates the pinion 30, and with it the notched hub 31, in a backward direction, the said pinion being free to rotate in this direction on the shaft 14. When the handle 46 has been thrown downward its full distance, the movement of the segment 44, and consequently of the lever, being determined in one direction by a stop 55 and in the other direction by a stop 56, the pawl 32 falls behind one of the notches of the hub 31 and locks the pinion 30 to the gear 33, and consequently to the shaft 14, on which the gear 33 is mounted. The motor is now set, but is held from rotation by means of the rocking escapement 40. When, however, the magnet 52 is energized, the releasing-lever 50 will be caused to turn on its pivot and assume the position shown in Fig. 6. The escapement is now released, and the spring 48, pulling downward on the arm 47, rotates the shaft 45, thesegment 44, the pinion 30, and the shaft 14, the rotation of the shaft being controlled by the action of the escapement in the ordinary manner. The pivoted latch 54, it may be here remarked, permits the downward movement of the arm 47, said latch turning on its pivot to permit the arm to pass.

The parts of the motor are so arranged as to permit the pinion 30 to make a half-rotation. The shaft 14 makes a half-rotation and causes the carrier 13 to make a half-rotation, during which time the contacts 15 and 16 are caused to successively pass over the circuit-terminals on the plates 6 and 7 and to close the circuits, provided the controller-fingers 21 and 27 areproperly set. The normal condition of the controller-fingers 21 and 27 will ordinarily be that shown in Figs. 3 and 7-that is, the said fingers will be out of contact with their cooperating fingers 22 and 28, so that the circuits will be open at these points.

Means which may be varied widely in form are provided in order to cause the controllers to close their-circuits as soon as the carrier begins its movement. In the construction shown pins 57, 58, and 59 are preferably provided for this purpose. These pins 57, 58, and 59 preferably extend inward from a front plate 61, said plate being secured to the supporting-plate 5 by means of screws 62 or in any other suitable manner. These pins lie in the path of the tumbler-blocks 20 and 26. As the carrier 13 starts to rotate the tumblerblock 20 strikes the pin 57 and rocks the controller, so that the fingers 21 and 26 are brought into contact. In'the same manner the tumbler-block 26 strikes the pin 59 and brings the fingers 27 and 28 into contact. As the carrier rotates, therefore, the contacts 15 and 16 sweep over and come in contact with the circuit-terminals of the sets 9 and 11 and send impulses over the circuits to be hereinafter described.

The form of construction which has been chosen-to illustrate the invention is a hotel signal-box in which it is proposed to give orders by means of numbers, the box being constructed to also indicate the number of the room in which it is placed and the number of portions to be served. The circuit-terminals on the plate 6 in the construction shown send .in the number of the order, while the circuitterminals on the plate 7 send in the number of the room and the number of portions to be served. The box in the present instance is adapted to send in any combination of numbers up to and including one hundred. To this end, therefore, the set of terminals 9 consists of ten terminals, and the set of terminals 10 also consists of ten terminals, the set of terminals 9 indicating the units of the number to be sent in and the set of terminals 10 indicating the tens of the number to be sent in.

Adjustable means are provided to break the transmitting-circuits after any desired number of impulses have been sent in. While these means may be varied in form in the construction shown, they consist of pins, said pins being in the present instance three innumber and being marked 63 64 65.

The front plate 61 is provided with three sets of numbered perforations, there being ten of these perforations in each set-that is to say, the number of perforations in each set corresponds to the number of circuit-terminals in each set. The first set of numbered perforations is marked 66 and is arranged to position the movable controller operating pin for the set of terminals 9. The second set of perforationsis marked 67 and is arranged to position the movable controller-operating pin for the set of terminals 10, and the other set of perforations is marked 68 and is arranged to position the movable controller-operating pin for the set of terminals 12. The perforations in each set are preferably of the same size and the pins are of the same size, so that the pins can be used interchangeably; but for convenience in description the pins 63 will be assumed to be used with the set of perforations 66, the pin 64 with the set of perforations 67, and the pin with the set of perforations 68. When the pins 63, 64, and 65 are in the proper perforations of the several sets, their inner ends will lie in the path of the tumbler-blocks 20 and 26 and will produce a movement of the tumbler blocks which is opposite to that produced by the pins 57 58 59. It maybe here remarked that in the movement of the carrier the tumblerblocks travel some distance ahead of the op erating ends of the contacts 15 and 16. The perforations of each set 63, 64, and 65 are not, therefore, arranged opposite the terminals with which the contacts cooperatethat is to say, the first perforation of each set is arranged some distance ahead of the first terminals and the succeeding perforations are .the same distance ahead of their corresponding terminals.

In order to make clear the operation of the device, it will be assumed that the occupant of a room desires to send in a given order (indicated by the number 74) and that it is desired that this order be served for six persons. The movable pins are accordingly set as indicated in Fig. 1that is, the units-pin 63 is set in the units-perforation 4, the tenspin 64 is set in the tens-perforation 7, and the pin 65, indicating the number of portions, is set in the perforation 6 of the set 68. When this has been done, the handle 46 is thrown down in the manner before described and the spring 48 placed under tension. The magnet controlling and releasing lever 50 will then be energized by circuits to be hereinafter described, so that the releasing-lever is thrown out of the way of the fan and the spring-motor allowed to operate. As the shaft 14 begins to rotate the tumbler-block 20 on the carrier strikes the pin 57 and throws the finger 21 against the finger 22. Similarly the tumbler-block 26 strikes the pin 59 and throws the finger 27 against the finger 28. As the shaft 14 turns, therefore, the contact 15 sweeps over and comes successively into contact with the circuit-terminals of the set 9 until it has made contact with four of these terminals and has sent four impulses over the line. When this has occurred, the tumbler-block 2O strikes the pin 63 and the finger 21 is swung away from the finger 22, so that no more impulses aresent in from the set of terminals 9. The number of the room in the instrument shown' will be indicated by a fixed number of terminals in the set of terminals 11, so that it is not necessary to insert a pin or operate the controller for the number of the room. As the movement of the carrier produced by the shaft 14 continues and the contact 15 is about to reach the first terminal of the set 10 the tumbler-block 20 is again operated by pin 58 to throw the finger 21 against the finger 22. The circuit is now closed again, and as the contact 15 strikes the first terminal of the set 10 it begins a second set of impulses, which continue until the tumbler-block strikes the pin 64, which was set in the perforation 7. Similarly the contact 16, the controller for which was set by the pin 59, sends impulses over the circuit which contains the set of terminals 12 until the pin is reached, this pin, it will be remembered, having been set in the perforation numbered 6. \Vhen the tumblerblock 26 strikes the pin 65, this circuit is broken. Itwillberemembered thatthemotor is arranged to give the shaft a half-rotation. When this rotation is completed, therefore, the shaft comes to a stop, and in the present instance there willhave been sent over the circuit in which the plate 6 lies a series of four units impulses and seven tens impulses which have been received on a suitable recorder, to be hereinafter described, and there will have been sent over the circuit in which the plate 7 lies a series of impulses indicating the number of the room (in the present case eight) and a series of impulses (in the present case six) indicating the number of portions to be served.

It may be here remarked that in the present form of the invention the dot-and dash system of impulses will be used, and the circuit-terminals are therefore made long and short in the order desired. It will be furthermore noticed that each set of terminals is spaced from the succeeding set, the purpose of this spacing being to separate the impulses given by each set of terminals from the impulses given by the succeeding set. The recorder-tape will therefore clearly show which set of impulses has been received from any given set of terminals.

Any suitable form of recording mechanism may be used with the signaling mechanism before described. Preferably, however, the recording mechanism will be a two-pen recorder operating with different-colored inks, though each pen may use the same colored ink, if desired.

The magnets for the recording mechanism are indicated in a circuit shown in Fig. 7, the said magnets being numbered and 71, respectively. A suitable indicator will also be used in connection with the signaling mechanism, and a single indicator-drop (marked 74) is shown in Fig. 7 as included in the circuit.

Any suitable system of circuits may be employed. One arrangement of circuits is indicated in Fig. 7, the main battery being marked 75. From this battery a wire 76 is led, the

said wire dividing into two branches 77 78, the wire 77 leading to the metallic support 5 of the signaling instrument and the wire 78 leading to a push-button or switch 79. From the other side of the push-button a wire 80 is led, said wire dividing into two branches, one of which, 81, leads to the plate 6, which, as before stated, is insulated from the plate 5. The other branch, 82, leads to the center part 83 of a plug-switch, said switch also having parts 84 85. The plug which cooperates with the switch is marked 86. From the part 84 of the switch a wire 87 leads to the indicator 74. From the indicator 74 a wire 88 leads directly to the battery 7 5. From the part of the switch a wire 89 is led, said wire passing through the pen-magnet 70, after which it divides into two branches, one branch, 90, leading to a relay-magnet 91 and from there by a wire 92 to ground 93. The other branch of the wire 89 leads by a wire 94 to a wire 95, which is connected with the wire 88. The wire 95 has a branch 96 leading to one part of a switch 97, and from the other part of this switch a wir 98 leads to the wire 92, before described. The magnet 91 controls a relay-circuit the battery of which is shown at 99. From one side of this batterya wire 100 leads through the pen-magnet 71, and from the said magnet another wire 101 leads to a switch 102, one part of which forms the armature for the magnet 91, as is common in such cases. The plate 5 is connected in any suitable manner, as by one of the screws 36, to a wire 103, said wire leading to a contact= finger 104. This contact-finger rests on a conducting-plate 105, which plate is secured to the insulating-block 17. Also resting on the plate 105 is a contact-finger 106, said finger being connected by a wire 107 to the plate 7. From the plate 7 a wire 108 leads to the magnet 52, before described as controlling the releasing-lever 50, and from this magnet 52 the circuit goes, by means of a wire 109, to the ground 110. The normal condition of the circuits is that shown in Fig. 7, except that the plug 86 instead of being between the parts 83 85 of the plug-switch is between the parts 83 84. lVhen the occupant of the room has set his call-box pins to send in any desired call, he throws the lever 46, thus putting the spring 48 under tension, and then presses the push-button 79, which is located near the signaling instrument. A circuit is now made from the battery 75, through the wires 76 and 78, to the push-button, from the push-button, through the wires 80 82, the parts 83 84 0f the plug-switch, and the wire 87, to the indicator 74. From the indicator 74 the current goes by a wire 88 back to the battery. This actuates the indicator, causing the proper drop to be released. When the clerk at the office or elsewhere is ready to take the order, he changes the plug 86 into the position shown in Fig. 7 and presses the push-button 97. A circuit is now made from the battery 75, through the wires 76 and 77, to the plate 35,

from the plate 35, by means of the stud 36 and the wire 103, to the contact-finger 104 and the plate 105, from the plate 105, by means of the contact-finger 106 and the wire 107, to the plate 7, from the plate7, by the wire 108, through the magnet 52 and the wire 109, to the ground 110, from the ground 93, through the wires 92 and 98, to the button 97, and from the fingers 22 and 28. As the contact 15 strikes the circuit-terminals in the set of terminals 9 on the plate 6 the circuit is made from the battery, by the wires 76 and 77, to the plate 5, from the plate 5, through the arm 13, the shaft 19, the fingers 21 and 22, the wire 23, and the contact 15, to the plate 6 by way of the successive terminals which the contact 1.5 touches. From this plate the circuit goes by the wires 81 82, through the parts 83 85 of the plug-switch, to the wire 89, and from this wire through the magnet 70, which is one of the pen-magnets of the recorder. After passing through the magnet the circuit goes, by the wires 90, 9t, and 95, to the wire 88 andto the battery. This circuit therefore causes successive impulses to be sent through the pen-magnet as long as the contact 15 continues to touch the circuit-terminals. As the contact 16 touches the terminals in the sets 11 and 12 on the plate 7 the current which went to the plate 5 by the wires 76 and 77 is divided, a part of it going to the shaft 19, as

before described, and a part of it going to the shaft 24:. From this shaft 24 the current goes, by means of the fingers 27 28 and the wire 29,

to the contact 16. As this contact touches the terminals in succession a circuit is made from the plate 7, by means of the wire 108, through the magnet 52 and the wire 109, to the ground 110. From this ground the circuit goes, by means of the ground 93 of the wire 92, to the relay-magnet 91 and then by the wires 90, 94, 95, and 88 into the battery. The operation of the relay-magnet is therefore substantially simultaneous with the operation of the penmagnet 70, and as the relay-armature is attracted a circuit is established from the battery 99, by the wires 100 101, through the penmagnet 71. Each of the pen-magnets is accordingly operated during the time when the contacts 15 and 16 are sweeping over the terminals.

It will be understood that the shaft 14 always rotates in the same direction. The contact 15 therefore cooperates with the circuitterminals on the plate 6 during one operation of the signal-box, and on the next operation "it cooperates with the circuit-terminalson the plate 7. It is not necessary to reset the box 'sition of the pins.

into effect.

or to return the carrier to its original position, as afterthe carrier has been operated to send in a set of signals and has ceased to send in this set of signals it is in condition to be again set to send in another set of signals.

The use of a recorder in connection with a signaling apparatus of this description is of particular importance, especially in hotel use,

since an exact record is automatically kept of everything which is ordered by the occupant i of a room. In case of dispute, therefore, as to any order the original record of the instrument can be produced.

While the invention is shown as embodied in an instrument intended particularly for use in hotels and other similar places, it is to be understood that it is by no means confined to this use. Thus, for instance, by doing away with the set of terminals 11, which indicate the number of the room, and making the set of terminals 12 a hundreds-circuit, the instrument could be readily adapted for use as a fire-alarm box, the adjustable pins being in this case set to the proper number of the box and always retained therein. By this change in the instrument a set of fire-alarm boxes would be produced which would send in any number up to a thousand, the boxes being all counterparts of each other except for the po- By utilizing the set of circuit-terminals 11 as a number-circuit also and using the impulses of this circuit to designate thousands a box would be produced capable of sending in any number of signals up to ten thousand.

Many changes may be made in the mechanical details by which the invention is carried It is understood, therefore, that the invention is not confined to the specific construction which has been hereinbefore dement between the circuit-closer and the sets of terminals whereby each of the terminals of each set and the circuit-closer may be brought into operative position and means whereby the closer may be caused to cooperate with a predetermined number of the terminals of each set during the continuation of the relative movement.
