SPECIFICATION forming part of Letters Patent No. 449,655, dated April '2, 1891. Application filed May 31, 1890. Serial No. 353,762. (No model.)
To all whom, it may concern.-
Be it known that I, FRANK ANDERSON, a citizen of the United States, residing at Peekskill, county of Vestchester and State of New 5 York, have made a new and useful invention in the Art of Telegraphy, of which the following is a specification.
Myinvention relates particularly to a novel method and apparatus whereby telegraphic codes are automatically transmitted and received through the agency of a prepared transmitting-record, and its objects are, first, to cause Morse or analogous characters to be automatically transmitted through the agency of an embossed orindented transmitting fillet or strip; second, to correctly reproduce an actual audible record of a Morse operators writing; third, to economize time in the various outlying line offices of a telegraphic system where inferior operators may be located; fourth, to furnish an easy and accurate system of educating persons in receiving by sound Morse or analogous telegraphic codes.
Prior to my invention it was old in the art to emboss or indent a paper or analogous fillet or strip with Morse or similar telegraphic characters, and to utilize such an indented or embossed fillet through the agency of levers 0 or analogous devices including an electrical circuit in which was located a receiving-instrument, either electro-magnetic, chemical,
or any of the equivalent or well-known types of telegraphic receivers; but with all such 3 5 constructions, so far as I am aware, it is customary to cause the indented or embossed characters to lift or elevate the circuit-closing lever or part a distance equal to the depth of the indenture or embossment, thereby depending upon the strength of the embossment and the slight depth thereof to cause the necessary contact for telegraphic work. All such devices, so far as I am aware, have failed to meet the demands made upon them, because 5 of the lack of certainty of contact maintained at each closure of the circuit by the embosslnents for the varied times represented by the dots and dashes which they effect. In my shown in diagrammatical view.
invention I overcome these difficulties by causing the embossments to simply carry or 50.
drag the circuit-closer forward in the direc' tion of motion of the embossed strip or fillet by a dragging contact, and I produce a firmness of contact at the circuitelosing points by placing said contact-points near the free end of a lever having its fixed endpivoted, as will be more fully described in connection with the accompanying drawings, to which reference is now had.
Figure 1 is a side elevatioual view of the entire apparatus, the electrical circuits being Fig. 2 is an end elevational view of the entire apparatus, as seen lookingat Fig. 1 from right to left. Fig.
3 is a detail view of the embossed transmit tin fillet or strip with a spring-pressed guide for holding it in place. Fig. 4 is an elevational view of a modified form of the apparatus.
Referring now to the drawings in detail, wherein like letters represent like parts wherever used, 'l is a paper or equivalent fil let orstri p, having Morse characters embossed in its face in three lines parallel to each other and prepared by an indenting device invented by myself, and fully described in a prior application filed by me in the United States Patent Office on the 28th day of March, 1890, Serial No. 345,777.
I have shown three rows of indentationsin the fillet T; but it is obvious that any number of such rows might be used. I prefer to use a number of such rows, for the reason that they give greater stability to the embossed characters, as will be understood in view of v the following description.
The prepared paper fillet T is'wound upon a reel R, secured to the frame A of the machine by standard N, and passes under a guide-pulley F, over a pivoted curvilinear 9o bearing-plate D, and finally between a driving-pulley B and grooved frictional pulley O,
pivotally secured to the frame by an arm a, and provided with an adjustable spring e, as
clearly shown in Figs. 1 and 2, the rows or embossed portions of the fillet being on the upper side thereof as it passes over the curved arm D. This arm D is pivoted at one end to the frame, and at its free end is provided with a handle cl, and has an adj usting-screw E and spring 0 for regulatingits vertical movement.
I is a pivoted transmitting-lever fixedly secured by a spring-support h to a metallic or conducting arm lI, electrically connected to the line-wire to, running to a distant or local station, as the necessities of the case require. On the lower end of the armIis a curvilinear spring 7c of sutficient width to cover the several rows of embossments on the fillet T. The arm I is also provided with an adjustmentspring e connected to an adj usting-screw L, secured to the frame, and carries near its lower end a pair of contact or conducting points, of platinum or other equivalent material, adapted to contact with similar adj ustable contactsi 2", secured to the frame A, and electrically connected by the wires w to the split battery BA, joined at its middle through an electrical conductor and switch 3 to earth at G. A similar earth circuit is shown in dotted lines with a second switch 5- and earth contact G which may be used when it is desired to transmit currents of one polarity, as will be hereinafter described.
Gr is a guiding strip or spring pivotally se cured to the frame and provided with an adjustment-spring 6 its free end being forked, so as to bear on both sides of the embossed record-fillet T, as clearly shown in Fig.
I will now describe in detail the operation of the apparatus: The prepared embossed fillet T having been wound upon the reel R and its free end carried under the guiding-roll F and between the brake-spring G, operatingspring 7:, and curvilinear guidingarm D, and finally between the driving-pulleys l3 and C, with the embossmcnts on the upper side as it lies upon the guiding-arm D, the driving-mo tor (not shown) attached to the pulley B is set in motion. As an embossment on the fillet T comes in contact with the free end of the spring 7:, the arm I is drawn forward until contact is made between its forward contactpoint and the contact '1', and the circuit is held closed for a dot or a dash, as the case may be. During the time that the free end of the spring 7.; is lifted and riding over the embossm cut a positive impulse is sentfrom the earth G, switch .9, and the right-hand portion of the battery BA, wire 10, contact 1;, arm I to the line-wire to. After the embossment passes under the free end of the spring 7c, the spring e" draws the arm I into the position shown in the drawings and a negative impulse is transmitted by the negative portion of the battery 13A through the wire 1r, contact i, arm I to line-wire to. It will thus readily be understood that when the forward end of any embossment strikes the free end of spring the arm I will be carried forward until a contact is effected with the contact-point and that the reliability of this contact as to pressure will depend upon the relative positions of the moving contact on the arm I, the fulcrum of the arm at II, and the distanceof the contact from the spring 7c. The relative position of the arm I and the movable transmitting fillet or strip D is such that it is substantially at right angles to said strip, so that when the latter is drawn forward by the pulley B when rotated in the direction of the arrow the embossed fillet will give tothe arm I a dragging or drawing motion, and it is obvious that the amount of this forward motion is independent of the height of the embossment. \Vith this arrangement of parts, therefore, wherein the movable electrical contact or contacts is or are located near the end of a long pivoted arm, I am enabled to give a sure or firm electrical contact with an embossment of very slight depth, a feature which has not been accomplished by devices of this generic type heretofore. In other words, the reliability of the electrical contact is made an element of a forward or dragging motion due to the embossment, of whatever depth, and notdependent upon its height.
In actual practice I find that I am enabled with this arrangement of apparatus to insure transmitting contacts with delicately embossed paper records, which are fully equal to those had in the use of Morse keys by skilled operators. In fact, the apparatus reproduces Morse records made by skilled operators upon the fillet T so accurately that when used receivingoperators, who are accustomed to read their writing in daily use, are unable to distinguish that the operators themselves are not actuallytransmitting. will thus be seen that I have devised an apparatus which so accurately reproduces Morse characters that all the peculiarities of individual operators may be correctly obtained, so that actual line-operators at outlying stations may have actual embossed copies of messages transmitted by any operator, and may reproduce them from time to time for the purpose of becoming acquainted with the personal peculiarities of such operators writing. It is also obvious that myimproved apparatus has a very desirable and importantuse in connection with learners who have only local instruments and no one to transmit or write Morse characters for them, itbeing understood that embossed messages may be prepared on transmitting strips and unreeled from the reel R at pleasure, the Morse sounder being situated in a local circuit instead of the main line. It will be understood how this may be accomplished if the switch 3 is disconnected from the ground G and the switch 5- is connected to the ground G a local sounder (not shown) being connected in a local circuit from the wire 10 to earth G under which condition of affairs the apparatus will operate on the closed-circuit principle through the front contact of the arm I and battery BA, or a circuit containing a lo cal battery and sounder might be connected to the frame A and post .l in a manner at IIO once understood by those skilled in the art. The wire-connections are shown without the battery and sounder in Fig. 2.
In Fig. t I have shown a modified form of apparatus in which the spring is secured to the arm I and bears upon the embossed fillet T, carried by an ordinary cylinder, the circuit beingopened and closed through point J and arm I as the embossed fillet '1 draws the spring 7; forward in a manner at once obvious.
I do not limit myself to the specific details of construction herein shown and described, as I believe it is broadly new with me to cause Morse or analogous telegraphic characters to be transmitted or reproduced over an electrical circuit through the agency of a circuit-closer, which is drawn forward and held closed by an embossed transmitting fillet or strip, and I desire it understood that my claims are of such scope as to include any apparatus by which this closure is effected through the agency of a drawing motion in contradistinction to a lifting motion such as I have disclaimed in the prior part of this application.
I am aware that it is old in the art of telegraphy to cause variations in an electricalcurrent passing through a conducting-arm resting on a rotary conducting-cylinder, to give to such conducting-arm a variable to-and-fro motion, and that such an apparatus is known in the art as a motograph relay, andI make no claim to any construction which does not contemplate the use of an embossed or indented transmitter in combination with a circuit-closer, which has given to it a dragging motion by the embossments or elevations on such transmitter.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

Atelegraphic transmitter having raised Morse or equivalent characters on a movable part, in combination with a pivoted transmitting-arm located substantially at right angles to the direction of motion of the movable part, and electrical connections, as described, whereby the characters are accurately reproduced electrically, substantially as described.
