Application 1116a March 25,1916. Serial No, 86,559.

To all whom it may concern: c

Be it known that I, CHARLES J. WILEY, a citizen of the United States, residing in Yorktown, county of VVestchester, and State of New York, have invented an Improvement in Printing-Telegraphs, of which the following is a specification.

My present invention relates to a printing telegraph and particularly to that type of such apparatus in which a plurality of instruments are employed in conjunction with a common tape and means for operating the instruments in unison to simultaneously print on the tape, or to operate the instruments independently of one another, including means operated to control the feed of the tape so that there is a predetermined slack in the tape between adjacent instruments.

In Letters Patent, No. 1,116,657, granted to me November 10, 1914, for a printing telegraph, there is shown anddescribed an apparatus in which the slack in the tape between adjacent instruments is obtained and maintained by means of a mechanical device operated by electro-magnets to force the tape downwardly under certain circumstances. In Letters Patent, .No. 1,146,985, granted to me July 20, 1915, there is shown and described a somewhat similar printing telegraph instrument in which mechanical devices are employed for supporting the tape intermediate of adjacent instruments and also raising the same under certain conditions to maintain a predetermined slack therein between adjacent printing instruments. 1 7

Now as hereinbefore stated my present ap plication relates to the same general class of printingtelegraphs. In the present case, however, I have dispensed with the electro-magnetically operated mechanical devices for lowering or supporting and raising the tape between adjacent printing instruments to maintain the necessary slack therein and accomplish this result by actuating the tape feed devices of the printing instruments. As hereinafter described this is accomplished. by operating the printing magnet of one instrument a suflicient number of times to draw the tape taut between the same and the next instrument and then by operating the printing magnet ofanother instrument a' suiiicient number of times to produce the necessary or desired slack in the tape. In carrying ou his leventlon I also inc ude means for bringing the typewheels of the pr nting, instruments/to umson or an initial starting polnt whenever the same 1s necessary or desirable by the operator in working the system in which the instruments are included. The manner in which these results are accomplished will be hereinafter more particularly described. In the drawing, the figure'is a diagrammatic illustration of a pair of printing instruments and the parts associated therewith to operate the same in accordance with my nvention. 1 I P v As illustrated in the drawing I have shown a printing telegraph in which two instruments areemployeda These are indicated respectively at A and B. The instrument Aisoperate d from a transmitter (land the instrument B from a transmitter D and it will be understood that while I have shown and will describe twoprinting instruments any number of the same may be employed, each instrument having anindividual transmitter. 'The printing instrument A comprises electro-magnets 10placed in alinement with anarmature 11 placed between their cores, and the armature, 11 is mounted on an escapement lever 12 pivotally mounted as indicated at 13. To provide for bringing the type wheels of the instrument to unison a yoke escapement is employed. One arm 14 of this is fixed to the lever 12 and the other arm 15 is pivotally connected thereto as indicated at 16, and is normally maintained in position with a pin 17 against a stop 18 by meansoit' a spring 19 extending between the arms 14 and 15 and suitably connected thereto. The arms'14 and 15 are provided with projections at their ends which cotiperate with an escapement wheel 20 in the usual manner. This escapement wheel :20 is mounted on'a shatt 21 on which a type wheel 22'is also mounted as is also a collar carrying apin 23, the function. of which will be hereinafter stated.

This printing instrument A also includes a unison magnet 24, the armature 25 of which is'secured on a lever 26 pivotally mounted at one end as'indicated at 27 and normally held in positionwith the armature 25 away from the core of the magnet by a spring 28. Adjacent the opposite end of the lever 26 the'same is provided with a projection 29. adapted to engage with a pin 30 on the end ofthe movable arm 15 so as to swing the same against the action of the v spring 19 when the lever 26 is raised in order to spread the arms of the escapement which permits the type wheel 22 to return to a unison or initial position in which the pin 23 strikes against the end 31 of the lever 26 bringing the type wheel and associated parts to rest.

The instrument A also includes a printing magnet 32, the armature 33 of which is connected to one end of a lever 34 pivotally mounted at 35 and normally maintained in position with the armature away from the core of the magnet by a spring 36. At the opposite end of the lever 34 are the usual tape feed devices 37 by means of which, when the lever 34 is raised by energizing the magnet 32, a tape 38 is raised to contact with the type Wheel and the feed device is actuated to carry forward the tape to a predetermined extent. Also associated with the escapement wheel and type wheel is a train of gears indicated at 39 40, 41, 42, 43 and 44 together with a suitable weight 45 by means of which, as is customary in escapements, the shaft 21 and type wheel 22 are operated through the actuation. of the escapement lever by the magnets 10.

The transmitter C employed in conjunction with the instrument A preferably comprises a suitable base 46 on which there is a series of contacts 47 placed in a circle. An actuating arm 48 is pivotally mounted at one end centrally of. the contacts 47 and adapted to be moved so as to bear against all of these contacts individually, it being understood, of course, as is usual each contact represents a character on the type wheel. A tooth wheel 49 is connected to the same arbor on which the actuating arm 48 is mounted and this is adapted to engage with the teeth on the adjacent sides of contact arms 50 and 51. These contact arms are also adapted to bear against adjustable contacts 52 and 53 placed on the outer side thereof and adjustable contacts 54 and 55 placed on the inner sides thereof. The contact arm 50 is pivotally mounted as indicated at 56 and is made to normally bear against the contact 54 by a spring 57, while the contact arm 50 is pivotally mounted as indicated at 58 and normally bears against the adjustable contact 55 by means of a spring 59. A battery 60 or other source of electricity is connected across the pivotal points 56 and 58 of these contact arms 50- and 51.

Also associated with the printing instrument A is a switch arm 61 adapted to be moved so as to make contact with either the contact 62 or the contact 63. Suitably connected in the lines as hereinafter described I also employ in conjunction with the'printing instrument A an electro-rnagnet 64, the armature 65 of which is secured in a lever 66 pivotally mounted at one end as indicated at 67 and normally maintained in pot sition with the armature away from the magnet core by a spring 68. Furthermore in the contact 63 there is mounted an ad justable contact 69 opposite which there is a similar contact 70 against both of which: the free end of the lever 66 is adapted to bear.

With the exception of the line connections the printing instrument B and the parts associated therewith are in all respects similar to those hereinbefore described as relat ing to the printing instrument A and consequently I will not specifically describe the parts comprising the printing instrument B, except by making reference thereto hereinafter in describing the operation of the apparatus.

In order to operate the printing magnet 32 and the tape feed devices operated thereby a predetermined number of times to regulate the length of the tape between the instruments A and B I employ an electromagnet 71, the armature 7 2 of which is connected to a lever 73 pivotally mounted at one end as indicated at 74. At or adjacent the opposite end of the lever 73 is a cross arm 75. I also employ a suitably ournaled shaft 76 preferably extending beneath the lever 73 and at right angles thereto and connected to this shaft 76 is a contact arm 77. The arm 77 as illustrated is secured in a sleeve 78 fixed on the shaft 76 and as it will be understood the arm may be connected to the shaft as shown or in any suitable manner. I also employ a stop arm 79 connected to the shaft 76. As illustrated this stop arm is pivotally mounted in a sleeve 80 secured on the shaft 7 6, it also being understood that the arm 79 may be connected as shown or in any suitable manner to the shaft 76. I also employ a shaft 81 suitably journaled in bearings 82 and provided with a drum 83 around which a cord or wire passes carrying the weight 84 and by means of which the shaft 81 may be turned. Upon l the shaft 81 there is also a commutator wheel 85 bearing against which is a brush or contact 86. Also on the shaft 81 is a worm 87. At one side the commutator wheel 85 is provided with a pin 88 and in the adjacent side of the stop arm 79 is a stop pin 89, and in the end of the stop arm 79 there is a pin adapted to engage the threads in the worm 87. The worm 87 is also provided with a stop pin 155, normally in line with the pin 88 on the commutator wheel 85. The stop arm 79 is normally held in the position shown in the drawing by means of a spring 91 in which position as will be understood the pin 88 is in contact with the stop pin 89 and the shaft 81 and its commutator wheel held in a stationary position. In this position as it willbe understood the contact arm 77 and the stop arm 79 are supported by the cross arm 75 so 87. These parts are so maintained by any suitable means for holding the armature of the magnet 71 away from the core there- 'of. When, however, the magnet 71 is energized and the armature attracted thereby lowering or moving the lever 73, the contact arm 77 is brought to bear against the shaft 81, the stop arm 79 so moved as to free the stop pin 89 from the pin 88, and bring the pin 90 into engagement with the threads of the worm. This frees the shaft 81 permitting it to be turned by the weight 84, or other means employed for this purpose, and the shaft'will continue to turn until the pin 90 comes into contact with the stop pin 155 when, of course, the shaft 81 will also cease to turn. The turning of the shaft 81 permits a circuit to be made and brokena predetermined number of times through a suitable linein which are connected the shaft and the commutator wheel 85, this circuit also including the printing magnet 32 so that the same is operated the same number of times the circuit is made and broken by the commutator wheel to feed the tape through the feeding devices of instrument A as may be required. It will thus be seen that any requiredslack in the tape may be obtained by operating the printing magnet 107 of the instrument B independently of the printing magnet 32 of the instrument A and that should the instrument B be operated faster than the instrument A the increased slack in the tape may be taken up by operating the electrdmagnet 71 to actuate the printing magnet 32 as hereinbefore described.

The other features embodied in my invention will be hereinafter described in connection with the operation of the instruments and the necessary circuits employed in so doing. As hereinbefore stated the instruments may be operated simultaneously,

or independently of one another. When operated together the switch arm 61 bears against the contact 62 and the corresponding switch arm 105 against the contact 104. The circuit for operating the instrument A from the transmitter C then includes a line 92 extending from the terminal 100 of the transmitter C tothe contact 62 through the switch arm 61, through a line 93 to one terminal of the printing magnet 32, through a line 94 from the other terminal printing magnet 32 to one terminal of the magnet 10, through a line 95 from the other terminal of the magnet 10 to one terminal of a unison magnet 96, corresponding in instrumentB to the magnet 24 in instrument A, then through a line 97 from the other terminal ofthe magnet 96 to one terminal of a magnet 98, corresponding to the magnet 64, from the other terminal of the magnet 98, through a line 99 to the opposite terminal 101 of the transmitter C. The circuit throughthe instrument B, beginning from the terminal 102 of the transmitter D, passes through a line 103 to the contact 104, through the switch arm 105 and a line 106 to one termi nal of a printing magnet 107 of the instrument B, from the other terminal of the printing magnet 107, through a line 108 to the one terminal of the operating magnet 109 of the instrument B, from the other terminal of the magnet 109 through a line 110 to one terminal of the unison magnet 24, from the opposite terminal of the magnet 24 through a line 111 to one terminalof the magnet 64, from the opposite terminal of the magnet 64 through a line 112 to the opposite terminal 113 of the transmitter D.

When either instrument is to be'used independently of the other the'switch arms 61 and 105 are set accordingly, for example, if the instrument B is to be used independently of the instrument A, the switch arm 105 is brought to bear against the contact 104 and the switch arm 61 isbrought to bear against contact 63. The circuits through the instrument B are the same as' those hereinbefore described. These circuits, however, including the magnet 64 will energize the same thereby attracting the armature 65 to the core of the magnet and, bringing the lever 66 to bear against the contact 69. This closes a circuit from one terminal 100 of the transmitter C through the line 114 to the lever 66-, through the contact 63,- the switch arm 61, the line 93, the printing magnet 32, the line 94, the operating magnet 10, the unison magnet 96, through the line 97, the magnet 98, through the line 99 to the opposite terminal 101so that the printing magnet 32 is actuated in unison with the printing magnet 107 so that the relationship of the tape to and between the magnets is constant. Assuming that the instrument A is to be used independently of the instrument B the switch arm 61 is made to bear against the contact 62 and the circuits for operating theinstruments A are the same as those hereinbefore described when the instruments are used in unison. The switch arm 105, however, is brought to bear against a contact 119 corresponding to the contact 63 and inasmuch as the circuits through the instrument A include the magnet 98 o ftheinstrument B, the armature 117 of this magnet will be at-' tracted to its core and will bring the lever 118, which is pivotally mounted at 116, against the adjustable contact in the contact 119. This closes a circuit through one terminal 102 to the transmitter D, to the line 115, to the lever 118, the contact 119, theswitch arm 105, through the line 7106, to

the printing magnet 107 to the actuating magnet 109, to the unison magnet 24, to the line 111, through the magnet 64, to the line 112, and to the other terminal 113 of the transmitter D. In this operation the auxiliary contact arm 153 is turned to the dotted line position in which it lies parallel to the contact arm 105.

The apparatus employed to operate the printing magnet 32 of the instrument A a predetermined number of times is connected with the electro-magnet 71 in a local circuit including a battery 120, or other source of electricity, through a line 121, extending from one terminal of the battery to a junction point 122 in the line 106, a line 123 extending between the contact 119 and one terminal of the electro-magnet 71, a line 124 extending between the other terminal of this electromagnet and the contact 63, together with a line 125 extending from a junction point 126' in the line 93 and including a switch 127, which is normally closed, to the opposite terminal of the battery 120. It will thus be seen that by bringing the switch arm 61 to bear against the contact 63 and the switch arm 105 to bear against the contact 119 this local battery or other circuit will be closed through the electro-magnet 71. When this electro-magnet isenergized and its armature 72 moved thereby the contact arm 77 is brought to bear against the shaft 81, and the pin of the stop arm 79 is brought into engagement with the threads of the worm 87 at the same time freeing the stop pin 89 from the pin 88. This closes a circuit through the contact arm 77, the shaft 81, the segments of the commutator 85, the contact 86, the line 128, to a junction point 129 in the line 93, thence by the line 93 to the printing magnet 32, through the line 94 to the operating magnet 10, the line 95 to the unison magnet 96, the line 97 to the terminal 157 of the magnet 98, the auxiliary contact arm 153, terminal 156 of magnet 98, the line 99, to the terminal 101 of the transmitter C, through the transmitter to the terminal 100, through the line 114 and 114 to the contact arm 77. This circuit is made every time the contact 86 bears against one of the conducting segments of the commutator and is broken every time the contact 86 bears against one of the insulating segments of the commutator. Every time the circuit is made and broken at the commutator, it is, therefore, also closed and opened'through. the printing magnet 32. This operates the printing magnet 32 to feed the tape 38 therethrough a predetermined number of times. Any suitable means may be employed to control the speed at which shaft 81 maybe turned. It will furthermore be understood that the printing magnet of the instrument B may be operated independently a sufiicient number of t mes if necessary to permit any required slack in the tape.

In operating the devices for actuating the printing magnet a predetermined number of times to take up the slack in the tape and make the same taut it is necessary to keep the printing magnet 107 and the devices operated thereby inactive as otherwise the tape would be fed through the printing instrument B at the same rate it is fed through the printing instrument A. As will be apparent from the foregoing description it is therefore necessary to cut out or short circuit the magnet 98 when the devices for op erating the printing magnet 32 are operated to actuate the tape feed devices a predetermined number of times in order to make the tape taut between the instruments. For this purpose I may employ an auxiliary contact arm 153 pivotally connected at 154 to the contact arm 105. This auxiliary contact arm is preferably provided with a handle 155 by which it may be swung to the full line position at right angles to the contact arm 105 or to the dotted line position in which it lies parallel to the contact arm 105,

would otherwise be the case if the magnet 98 werenot short circuited. Also as will be understood when the instrument A is to be used independently of the instrument B, as hereinbefore described, the auxiliary contact arm 153 is moved to the dotted line position so that when the arm 105 bears against the contact 119, the auxiliary contact arm will not short circuit the magnet 98.

In order to operate the unison magnets which it will be understood are so wound as not to operate with the current ordinarily passed through their coils in using the printing instrument-s, I employ circuits for sending a current of increased strength through either one or both of these unison magnets. For this purpose the unison magnet 24 of the instrument A may be operated by a battery 130, or other source of electricity, one terminal of which is connected by a line 131 to a junction point 132 in the line 106 while the other terminal of the battery 130 is connected by a line 133 in which there is a switch 134 to a junction point 135 in the line 111. This line is normally open but by closing the switch 134' a current of increased strength may be sent through the line 133 to the line 111 through the unison magnet 24, the operating magnets 109, the printing magnet 107, and through the line 131 to the other terminal of the battery to energize the unison magnet 24 and operate the devices hereinbefore described for moving the type wheel of this instrument to its unison position.

Similarly I may also employ a battery 136 one terminal of which is connected by a line 137 to a junction point 138 in the line 97. The other terminal of this battery is connected by a line 139 in which there is a switch 140 to a junction point 141 in the line 93. This closes a circuit through the line 139, the line 93 to the printing magnet 32, the line 94, the operating magnets 10 of the instrument A, thence by the line 95 to the unison magnet 96 of the. instrument B, and by the line 97 to the line 137 to the other terminal of the battery. This as it will be understood energizes the unison magnet 96 attracting its armature 142 and actuating the lever 143 against the action of the spring 144 and causing the projection 145 to strike the pin 146 thereby swinging the arm 147 against the action of the spring 150 and permitting the type wheel of the instrument B to return to its unison or initial position in which it is brought to rest by the stop 149 coming in contact with the end 148 of the lever 143. When returning to their operating positions the action of the spring 150 brings the pin 151 against the stop 152 in which position the escapement is normally operated.

' As herein illustrated I have shown diagrammatically an apparatus for closing a circuit through the printing magnet of one instrument to regulate the feed of the tape but as it will be understood any apparatus constructed to perform the same functions may be employed without departing from the nature or spirit of my invention, and also while I have shown the circuits for operating the unison magnets independent of one another I may employ a switch so constructed as to be normally open and to be moved to close either one circuit or the other.

From the foregoing it will be apparent that in the use of my invention the instruments in any apparatus may be used together simultaneously or either instrument may be used independently of the other, that by closing a local circuit associated with any apparatus means are provided whereby the printing lever and tape feed devices may be operated a predetermined number of times 2.
