TELEGRAPI-IING INSTRUMENT.

Specification of Letters Patent.

Patented June 25, 1912.

Application filed April 4, 1911. Serial No. 618,800.

To all whom it may concern:

Be it known that I, CLAYTON C. FERGU- SON, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Telegraphing Instrument, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to produce an instrument of the character mentioned which is attachable to a typewriting machine for use in conjunction therewith whereby the telegraphing instrument is operated in harmony with the typewriting machine; to produce an instrument of the character mentioned which may be adapted as an attachment to typewriting machines of usual construction; to provide an attachment of the character described wherein the telegraphing circuit is closed when the use of the instrument is discontinued; and to provide an instrument of the character depicribed the construction whereof is simpli- One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which Figure 1 is a longitudinal vertical section of a typewriting machine and telegraphing instrument of the character mentioned shown in operative relation; Fig. 2 is a plan view of a telegraphing instrument, the type writing machine being removed; Fig. 3 is a cross section taken on the line 3-8 in Fig. 4, of the platform of the telegraphing instrument and the sliding head mounted thereon, showing in elevation the rocking member for opening and closing the line circuit; Fig. 4 is a longitudinal vertical section of the telegraphing attachment con structed and arranged in accordance with the present invention, showing in connection therewith a telegraphic sounder and typewriting machine key bar in operative position; and Fig. 5 is a detail view in vertical section showing the plate for mounting the telegraphing key bars in elevated position.

The typewriting machine shown in the accompanying drawings is provided with the usual number and arrangement of key bars 9. The key bars 9, as shown, are operatively connected with type blocks 10. The writing machine is provided with a base flange 11 to be held in grooves provided in the upper end of

standards

12, 12 when the said writing machine is mounted upon the telegraphing instrument constructed and arranged in accordance with the present inventlon.

The electric circuit members for operating the sounder 13 consists, in part, in a wire 14, main 15, binding post 16, plate 17, carriage 18 and contact spring 19, which constitute the members on what may be termed the main line side of the circuit. The spring 19 is employed to make and break the circuit by contacting with the plug of a binding post 20, which is incorporated in what may be termed the ground side of the circuit in which is incorporated the telegraphing machine. The ground side of the circuit consists in the binding post 20, which includes the adjusting plug thereof, a bridging wire 21, stud shaft 22, roller 23, arm 24, pin 25, hinge wing 26 and ground wire 27.

In the ordinary course of operation of the present telegraphing machine the operating circuit for the sounder 13 is closed when the spring 19 is brought into contact with the binding post 20, and broken when the said spring is removed from contact with the said post. To effect this operation of the spring 19 there is provided a rocker bar 28, which is pivotally mounted on a carriage supported on a platform 29 by a wheel 30. A supporting arm 31 is provided 'to permit the rocker bar 28 to be removed from its bearings, the arm 31 yielding to remove the bearing provided therein from the endof the said bar. The bar 28 has rigidly secured thereto a lever 32, the end 33 whereof is looped to encircle the end of the spring 19, as seen best in Fig. 3 of the drawings. In the normal position of the spring 19 it is depressed toward the plate 18 away from the post 20. The spring 19, therefore. rocks the bar 28 so that the upper edge thereof is maintained in substantially vertical disposition. The bar 28 is curled at the ends 34, 34: to form rests and threading portions for the string 35. In the present instance the string 35 is constructed from catgut. and is fixedly secured by being threaded through a channel formed in the

ends

34, 34; and hooked over securing plates 36, 36. The

plates 36 are of any suitable and usual construction. The string 35 is by this arrangement adapted to be easily and readily replaced.

To rock the bar 28 there are provided the

key bars

37, 37. The

bars

37, 37 are each provided with a series of cam-

shaped members

38,38. The

members

38, 38. are extended from the under side of the bars 37 when the said bars are placed in operative position, in which posit-ion of the bars the cam members 38 extend below the normal Y level of the string 35, as seen best in Fig. 4

of the drawings. The key bars 37 are shaped substantially as shown in said F 1g.

4, and are mounted upon a plate 39. The

plate 39 is disposed transverse the plat-form 29, and is hinged upon the said platform by means of the

hinge wings

26 and 40. The attachment of the bars 37 to the plate 39 is by means of folded clip ends 41, the said clip ends being adapted for extension over the plate 39 to hold the same in gripping relation. Between the clips 41 and the rigid portions of the bars 37, the said bars are provided with a spring portion 42, which yielding, permits the retention of the bars 37 on a rest bar 43 when any one of the said bars 37 is depressed and held by the key bars 9 of the typewriting machine.

Normally the

key bars

37, 37 rest at their forward ends upon the rest bar 43. In this position the carriage 18 is pushed rearwardly on the platform 29, and in position where the stud shaft 22 and roller 23 are in line with the upturned section 44 of the arm 24. The disposition of the roller 23 is such that when the carriage 18 is drawn toward the front of the platform 29 the roller rides from under the raised portion 44 of the arm 24 and under the forward and depressed portion of the said arm, lifting the said forward portion and with it the forward edge of the plate 39 to which the arm 24 is rigidly connected, as seen best in Fig. 2 of the drawings. Rocking the plate 39 in this manner lifts each of the

key bars

37, 37 unless the same is held in its d'epressed position to rest on the bar 43 by one of the key bars 9 of the typewriting machine. It is in this position that the cam members 38 formed on the key bar 37 which is thus held by the key bar 9 impinges upon the string 35, forcing the same backward;

thereby rocking the bar 28 and lifting the lever 32 connected therewith. The lift of the lever 32 operates to lift the spring 19 into contact with the post 20, closing the electric circuit which operates by the sounder 13.

Each of the key bars 37 is provided with short and long cams 38 disposed to effect on each key bar a separate arrangement designed to produce telegraphically one letter of the Morse telegraphic alphabet. The key bars 37 are disposed on the plate 39 with reference to the key bars 9 of the typewriting machine. Each of the bars 37 is provided at the forward end with a foot 45 upon which the corresponding key bar 9 of the typewriting machine rests when depressed to operate the type block 10 to which it is connected. In the selection of the key bars it will be understood that the elevated arrangement of the said key bars corresponds with the elevated arrangement of the key bars 9 of the typewriting machine, so that the key bar 37 held in depressed position by the key bar 9 of the typewriting machine is provided with the cam surfaces 38, 38 shaped to produce short and long dashes and intervals correspond ing with the Morse telegraphic alphabet identified with the typewriting character of the key bar 9 which is depressed.

In the operation of the telegraphing instrument herein described it will be understood that after each of the key bars 9 of the typewriting machine is depressed the carriage 18 is drawn forward to the rest bar 43, the string 35 riding under each of the cam surfaces 38 to lift the spring 19 to contact with the post 20 as the carriage is so moved. As the key bar 9 is released the spring portion 42 thereof lifts the cams from the path of the string 35 when the said carriage 18 is retracted. It will be noticed, however, that due to the resiliency of the string 35 if the key bar 9 should be accidentally returned in its depressed p'osi tion the string will pass under the cam surfaces without lifting the spring 19, the rocking direction of the bar being the reverse of that by which the lever 32 is lifted. To aid in the operation of the carriage '18 I have provided a side plate 46. Upon the plate 46 may be mounted any suitable device for advancing and retracting the car riage- 18, hand or otherwise operated.

The

bars

37, 37 are normally maintained in their depressed position by a spring rod 47 upon which tracks a roller 48. The roller 48 is rigidly mounted on a bracket 49, the bracket 49 being rigidly mounted on the plate 39. normal position the roller 48 is extended to the side of'the hinge pins of the

hinges

26 and 40 removed from the body of the bars 37. The lift of the spring 47 upon the said roller 48 therefore tends to depress the opposite edge of the plate 39 and the bars 37 connected therewith. When desired, the plate 39 is rotated into position as shown in Fig. 5 of the drawings, wherein the plate 39 is held in substantially vertical disposition. It is in this arrangement of the plate 39 that the bars 37 are mounted thereon.

The operation whereby the plate 39 is rocked to depress the forward ends of the bars 37 also operates to depress the for- It will be observed that in its ward end of the arm 24, causing the same to contact with the plate 17 This is the position of the parts under normal conditions when the carriage 18 is retracted. It is in this position that the current in which is incorporated the sounder 13 is closed as far as this instrument is concerned whereby the sounder may be operated on the line. It will be noted that the arm 24 making contact with the plate 17 operated to cut out the spring 19 and post 20, the circuit passing through the said arm 24 direct to the hinge 26 through the pin 25 and thence by way of the wire 27 to the ground.

Theoperation of the instrument is as follows: The typewriting machine is placed on the

standards

12, 12. The key bars 37, 37 are adjusted with reference to the key bars 9 of the typewriting machine to register the said key bars of the typewriting machine and telegraphing instrument with reference to the alphabetical character which they represent. This having been efl'ected the operator of the typewriting machine depresses a key to print on the paper carried by the machine a certain character. The key bar 9 effecting this character is depressed upon the foot 45 of the key bar 37 directly beneath, holding the same upon the rest bar 43. Immediately the carriage 18 is moved forward to the rest bar 43, the variously shaped and spaced cam surfaces 38, 38 operate to rock the bar 28 to thereby lift the spring 19 into contact with the post 20 to cause intermittent short and long dots and dashes and intervals disposed between the same, in conformity with the Morse telegraphic alphabetical symbols. During the sending of a message, when each key bar 9 is released, the carriage 18 is retracted to a position on the table 29 beyond the field of the cams 88, but forward of the upturned section 44 of the arm 24, and thus supports in raised posit-ion the end of the said arm. From this position the carriage is again moved forward as soon as the next succeeding key bar 9 is depressed. Throughout the sending of the message it will be noted that the arm 24 is held out of contact with the plate 17. lVhen the sending of the message has been completed the carriage is further retracted to place the supporting roller 23 under the upturned section 44 of the arm 24. The clearance afforded by the upturned section 44 permits the arm 24 to settle on Copies of this patent may be obtained for five cents each, by addressing the the plate 17 to complete the relay or closed circuit of the instrument.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is 1. In a telegraphing instrument, the combination with a typewriting machine having depressible key bars, of a plurality of auxiliary key bars disposed beneath said depressible key bars to be depressed thereby, each of said auxiliary key bars having projections formed thereon and disposed concordantly with the electric telegraphic alphabet; and an electric circuit making mechanism extending across said auxiliary key bars and movable lengthwise thereunder to be rocked by said projections when said auxiliary key bars are depressed.

2. In a telegraphing instrument, the combination with a typewriting machine having depressible key bars, of a plurality of auxiliary key bars disposed beneath said depressible key bars to be depressed thereby, each of said auxiliary key bars having projections formed thereon and disposed concordantly with the electric telegraphic alphabet; an electric circuit making mechanism extending across said auxiliary key bars and movable lengthwise thereunder to be rocked by said projections when said auxiliary key bars are depressed; and a supporting base for said auxiliary key bars, said base providing supports for holding the typewriting machine and the key bars thereof in register with said auxiliary key bars.

3. A telegraphing instrument, comprising a platform having a plurality of electric circuit terminals; a pivoted member to normally connect said terminals; a reciprocating carriage movable under said pivoted member to discontinue the engagement of said member with one of said terminals; a rocking mechanism mounted on said can riage for completing a telegraph circuit; and a series of selective keys each individually formed to rock said rocking mechanism when said carriage is reciprocated.

In testimony whereof I have signed my nam'e'to this specification in the presence of two subscribing witnesses.
