SPECIFICATION formingpart of Letters Patent No. 228,585, dated June 8, 1880,

' Application flledMay 3, 1a19.

To all whom it may concern:

Be it known that we, FRANK'ANDERSON, of Peekskill, in the county of Westchester and State of New York, and THEODORE M. FOOTE,

50f llewYork city, New York, have'invented certain new and useful I-mprovementsin Meohtom of transmitting positive and negative currents over a line or conductor by means of perforated paper, whereby, after each recording impulse is sent, an impulse of opposite po- '2 5 larity is transmitted for freeing the line and insuring legibility of the characters-at the re-.

' ceiving-instruinent.

The last-mentioned patent relates to a system of transmission of negative and positive 0 currents over a line or conductor by means of perforated paper, whereby alternate currents of positive and negative electricity are transmitted over a circuit and each impulse made available lor recording at the receiving-instrument. 1

The present invention is specially adapted to perlbratin g the paper fillets employed in the above-mentioned systems oi'telegraphy. It is further designed to provide a means by which 40 thcspacebetween theletters, usuallyleft blank, is perforated wholly or in part by a single row of peribrntions, the object being to record in the space between each two letters, usually left blank, a series of dots in one row, which, 5 in long lines, the recordingourrent having been transmitted from one pole of the battery,

will be lengthened out and invariably recorded as a dash, in any case, however, distinctively marking the space between the letters.

It is essential'inthese systems. that the component perforations forming 'the integral perforations representing the characters should alternate, and as the characters of the Morse, international, and other character-alphabets employed are composed of an even and uneven number of integral component 1 arts,'the perforations would not always alternate properly. Therefore mechanism for eifecting this is of vital importanceto the transmission of a telegraphic message by alternating currents of positive and negative electricity.

The present invention is especially designed to produce the perforations in the paper employed inthe above-mentioned systems.

The special features of the invention consun; in the mechanism foroperatin g the punches and selecting the number necessary to form the perfiorations corresponding to each character to beproduced at the receiving-instrumcntfor alteimating or reversing the position of the perforations when characters of an uneven number of parts succeed each other in order to prevent two positive or two negative impulses from following each other, which would preventthe proper alternation in the our- 7 5 I rent necessary to produce the characters at the receiving-instrument, and to provide for automatically feeding the paper in proper varying lengths, as more fully hereinafter set forth.

In the drawings; Figure 1- represents a top view of our improved apparatus. Fig. 2' represents a sectional View on the line was of Fig.

1. Fig. 3 represents a side elevation. ofthe apparatus; Fig. 4, a detached view of the mechanism for operating the bar carrying the 8 5 punching and paper-feeding mechanism. Pi 5 represents a detached view of the mechanism for operating the punch-selecting bars. Fig; 6 represents a diagram of a perforated paper for producing the impulses. Fig. 7 represents de- 9o tached views of the punch-head and punches; and Figs. 8,9, 10, and 11 diagrams representing tne ditfercnt methods of forming the perforations.

The let-ter'l. represents a continuously-re; 5 volving shaft driven by any suitable power. Said shaft'has rigidly secured to it a ratchet. wheel g', and has mounted on it aloose sleeve,

2' v I ceases J, which. carries" two cam-disks, H M,adapted apawl or clutch,

' a normal position by means of a short lever,

m, pi\ 'o'ted to the stan 'lard,,and while in said position engages the end of the pawlor clutch h and holds it away from the ratchet-wheel j, permitting the shaft I to revolve independently of the,slee ve J and its attachments.

The letter P indicatesa'reciprocating latchbar, connected, byneans of an angle-lever, g, and bar W", with an oscillatingframe, Q, pivoted in suitable bearings andextending transversely .below the key-levers, hereinafter more. fully described, so as to be oscillated thereby. when one of such levers is depressed, the said frame being held in a normal position by means;

at a spring. The said bar IP is provided near its forward end with an upright projectiomp,

which sets directly under the lower arm of the an gle-lever i, Fig. 4, and forward of said projection is provided. with a shoulder, which serve to engage the lower end of the lever m and trip it when the bar 7 is drawn back by All!) depression of one of the keylevers, so as .to release the angle-lever and permit it to be shifted by 1 ne ans of the spring Z, fro1n its normal position. The lower arm of said angle-- lever, when in its normal position, engages the lower end of the pawl orclutch h and holds it away from the ratchet j on the shaft; but when it is shifted it releases said pawl. which will be thrown into gear with the ratchet-wheel by means of the spring I, so as to carry the sleeve J with the rotating shaft.

The disk H on the sleeve J is provided at its periphery with a projection, at, which serves to trip the angle-leveri '5 after the sleeve has completed one revolution and return said lever to its normal positiomso as to engage the lower end of the clutch or pawl h and release it from the ratchet-wheel.

Thebar P is capable of a slight oscillating movement in a vertical position by means of a spring. I

\Vhen the angle-lever i i is thrown out of normal position by the operation of the bar P and lever m, the lower arm, t, of the said angl'e-lever bears against the projection pen the bar I" and holds it down,.so as to keep the catch, m? clear of the lower end of the lever m. When the angle-lever is tripped by the projection a on the disk h, the arm 1' will be elevated, permitting the lever m to spring under its end, and releasing the pressure upon the plOJGGllOll 2), allowing the bar P to be elevated,

so that the catch an will engage the lower end.

of the lever m, so that the lever on will be tripped by said catch m at the next ile'oression of a key-lever. v

The letter G indicates alever, iulcrumed at which is adapted to be thrown into and out position by means of suitable springs.

g, its upper end bearin g against the cam Den the sleeve J To said lever is connected one end of a reciprocating bar, F, to the other end of which is attached thepunch-head A. Said bar and lever are held'in a normal position by means of a spring, k, and are shifted so as to operate the punch-head by the cams L, when a key is depressed and the sleeve J is rotated by the revolving shaft I.

The letter E represents the key-levers, which are fulcrumed at e and extend forward to the front of the-apparatus, terminatmgin a series of keys, E. Said levers are held in anormal The letter 0 represents a. series of end on a rod, 0, the opposite ends being fitted into a sliding rack-bar, .D. The said supplementary levers are arranged directly over the key-levers E.

To the rear ends of the key-levers are secured transverse pieces f, which serve to raise the supplemen tany levers or bars 0 upon the depression. of the keys.

These pieces f are locatedsuccessively nearer the ends of the respectivelevers as they recede from the fulcrums of the punch-selecting bars, as shown 8o supplemen tary levers or bars havn'ig bearings at one in Fig. 1 of the drawings, in order to elevate the said punch-selecting bars the same distance-at the depression of each key, asmore fully hereinafter specified.

The letter B indicates the punch-selecting bars, which extend transversely over the ends of thesupplementary levers or bars 0, and are pivoted at one end, as indicated at b. The opposite ends o'fisaid levers or bars are shaped to correspond with the punches, so that when they are elevated and brought opposite the ends of the said punches they will actuate them in proper. order to make the necessary perforations in the slip of paper. The lower edges of these punch-selecting bars are notched or recessed, as indicated in Fig.5, in such relation to the keys and supplementary bars that when a punch-selecting bar is not required to actuate the proper punch in the formation of a perforation the supplemental lever or bar will be thrown into the notch or recess as it is raised, leaving such punch-selecting bar in a nornialpositionand elevating. theother punch-selecting bars to operate in conjunction with the punches to form the perforations for producing the'required character.

The. selection of the punch-selecting bars or levers, l1owever, further depends upon the position .given' to the supplemental levers, as

ceases 2 Stand which is located transversely under the key-levers The depression of certain keys, serves to oscillate said frame, giving a reciprocatin g movement in a backward direc 'tion to the arm as, which carries the ,pawl I into, the next tooth of'the ratchet-wheel W.

Upon relieving the key of the pressure and releasing it the frame is returned to its normal position by the spring S,.thus throwing the arm and pawl in to their normal positions and moving the cam-wheel forward to the extent of one tooth.

The cam-wheel W is prevented from moving backward by the pawl P acting in and upon the ratchet-wheel W.

The reciprocating rack-bar D carries a pin, to, which is operated by means of the cams on the cam-wheel W and the spring 20 to ,move said raelebar back and forth at each depression of the keys and shift the supplemental bars to the right or lefta given distance, and change the positions of the respective supplementary bars or levers (J, in order to alternate the punch-selecting bars or levers, said supplementary levers, when in position to the right, serving to elevate one series of punch-selecting levers, and when in position to the left to releasethe first-mentioned bars and elevate others to act in conjunction with the punches.

As it is essential for the system herein mentioned that the com pouentperforations forming the integral perforation representing the character shall alternate, it becomesnecessary that the polarity interchange shall be effected when the integral perforations consist of an uneven number of component parts. If the integral perforation for a character, as is shown at S, Fig. 9, consists of an even number, then no change occurs for the next letter. If, however, the perforations are unequal, as at I I, Fig. 9, then achange must occnrfor the next letter, the change being made only when an uneven mnnber of, punches are used, and this occurs only on certain characters, as is well known, in which the key-levers of such characters rest on the frame It, so that the depression of the key will swing the frame and actuate the devices, as aforesaid.

The key-levers of such letters that require only an uneven number ofpunches to make the character are provided with a recess, as shown at 10, Fi g. 3, that will permitsuch levers, when depressed, to pass over the frame R.

A represents a punch-head, carrier, or support for the punches a. Said punch-head is supported in position opposite the punch-selecting bars in any suitable manner, and is so arranged that a reciprocating movement may be given to said punclnhead by the rod F, attachedto the upright arm G, which is pivoted at y, and'has a roller, g, secured to it. Said roller giiiipinges or rests upon the cam L, and is held firmly thereon by the spring k, as before mentioned. As the cam L is revolved a forward motion is given to the punch-head A by the action of the lever G and rod F, the

spring 7.- scrving to return the punclnhead to its normal position immediately after the point of the cam farthest from its axis has passed the roller g.

In lieu of the spring I. for returning the punch-head to place, a second cam or eccentric maybe used, thereby giving a positive and easy to-andfro motion of the punch-head by the same power and with the least shock to the parts, and with but little noise.

Attached to the punch head or carrier is a metal bar, Z, which passes across and between the punches 0. 1, lit-ting into the recesses in the same, the bar Z serving to keep the punches (to clear of the bars 15 when at rest. Attached to the frame or support I) is a bar, y, similar to the bar Z, which serves to draw the punches from the die 11' as the punch-carrier returns to place.

By the use of the pieces 1/ and Z springs that are objectionable for returning the punches are dispensed with and a positive and reliable movement obtained.

While we have shown but six punc1i'es three in each row-it is well understood that form the perforated characters.

The letter Y indicates a series of auxiliary bars, pivoted at b to the support, and parallel with the punch-selecting bars 13. The said auxiliary bars are provided with shoulders r near their forward ends, which are formed at varying distances from said ends, for the purpose of regulating the movement of lever V. The arm V is secured by a shouldered screw to a support, T, and the arm tis pivoted to a support, t and carries a pawl, P', which engages and operates a ratchet-wheel, W seas many maybe used as may be required to cured to a drum, S, journaled on a support, d. 4

The said arm V is connected to an arm, 2, by means of a link, V, so that the two will move together. The arm V is also seemed to arod, U, which is connected to an oscillating lever, u, fulcrumed at c The arm it carries a fric-. tion-roller, a, which bears against the cam M on thesleeve J. As the said cam M is rotated the rod U is drawn back from the punches by a spring it until caught by one of the bars Y, which serves as a stop to limit the movement of the arm V and control the distance of its oscillation, and regulate the feed of the paper to correspond to the length of the perforations for each particular character, the said rod being driven forward by the cam M after being arrested by the bars Y, giving a partial rotation to the drum S by the action of the pawl P in connection with theratchetwheel W'. A roller, 8, is arranged to bear against the fillet of paper and press it against the periphery of the drum S, so as to draw it through the die at eachmovement of said drum and present a fresh portion of the paper to the punches, the movement of the paper, as before stated, depending upon the movement of the arm \r,

which is regulated by the spacing-bars, whichare elevated one at a time, the particular spacing-bar elevated depending upon the length of the integral perforations to produce a given character.

In the several diagrams-indicating the perfo-' rated strip, the letter a indicates the.component parts of the integral perforations representing the characters, which alternate, as

clearly shown in Fig. 6, from one line to the the component parts of theintegral perfora tidns require to be reversed, as indicated by. the integral perforations representing the let ter S,'l3ig. 6, in order that the perforations may alternate properly.

In operation the action as follows Motion being imparted to the main shaft I by any suitable power, upon depression ofa key-lever bearing on the frames Q R the same are depressed, and the following movements take place: The frame Q, upon being depressed, carries forward the c'onnect ing-rod r which oscillates the bell-crank lever q, giving a backward motion to the catch on of rod P, which trips the oscillating stopanchor m, which permits the hell-crank lever t t" to be thrown into position shown in Fig.

-4. The arm 23, disengaging from the clutch-h and resting upon the stop-pin p serves as a lock to the stopanchor m, while the point i rests upon the surface of the flange H of the sleeve L. As the arm I is disengaged from the clutch h the clutch is thrown down upon and intotheratchetwheel jby the spring I, and revolves therewith one complete revolution at each depression of a key, and is thrown :out or disengaged therefrom by the cam n in its revolution coming against the arm tand throwing the arm trip 'into the path of the clutch It, where it is held by the stopanchor m, being thrown by the spring 8'" against the pinp" and underthe arm '5, so that i acts as a stop to the clutch h. Simultaneously with the depression of the frame Q the frame It is depressed, moving the rod 1' attached thereto and the arm X forward, and

consequently the pawl 12, which is made totake another tooth in the ratchet-wheel W, the wheels W and W being held in place by the stop-pawl p Simultaneously therewith the leverE of the key, depressedat the point f, raises one of the supplementary bars'G, which in turn raises one or more of thepnnchselectin g bars 13 and one ofthe ieed-regulatiug bars Y. It will be perceived, then, thatthe depression of the frames Q R, the action of the devices r q I p, M 'i i h and devices r o 2 and the raising of the bars Q B Y all occur in the same instant or period of time.

of the apparatus is" Immediately upon the clutch taking into the revolving ratchet or spur wheel j the said clutch and the camson the sleeve J become a part of the shaft I, and revolve therewith, and the following movement-s take place: The cam L acts upon the roller 9 on; the lever G, moving, by means of the connecting-rod. F, the punch-carrier forward and the punches up to and against the punch-selecting baRS that have been raised, thereby driving the punches into the die at and perforating the paper, the-spring is serving to throw thep'un'clr carrier back to place immediately as that part of the. cam farthest from the axis has passed in its revolution the rollerg'. Simultaneously with the movement of the cam L the cam M changes its position and permits the spring u to contract and move the rod to 'and the arm Vback from the paper until. the arm V is stopped by the raised-paper feed-spacing bar Y. The cam L and cam M are so arranged in relation to each other that immediately after the cam L has carried the punch-head forward and perforated the paper, and permitted-the return or partial return. of the punch-carrier and the withdrawal of the punches from the paper, the cam M, in its revolution, drives the rod-U, arm V and t.forw ard, partiallyrevolvin g the roller S by the action of the pawl p on the ratchet-wheel W", the movement of the paper depending upon? the backward movement ofthear-m V, which is regulated by the bars Y, as hereiubefore explained. p a

it will be observed-that the above-described operations take place upon the depression of the key.

The operations and movements that occur when the key is released are as follows: The frame (,3 is returned to place by the spring 3, thereby carrying the catch on by a forward lateral motion into normal position, as shown 'in Fig, 2. Simul-taneouslytherewith the frame it is returned to place by the spring 8 Fig.3, which carries forward the rod 1', arm X, and

pawl 12", Fig. 5, driving the compound camwheel by means of the ratchet-wheel W, the wheel W, in turn, in its movement acti n g on the pin w in the rack-bar D, and held against W by the spring a, carriesthe rack-bar D and supplementary bars 0 to the right or left, thereby changing the position of the bars 0 in relation to the levers E and bars B. Shouldnow the same key be again depressed thesame movements would occurand the same results be obtained, excepting only that, the position of the bars 0 having been changed in relation to the bars B and levers E, different punch-selecting bars B would be raised and difierent punches used; and if, for instance, the character punched had been as shown in Fig. 10, upon repeating of the same they would appear as shown'in Figtll, the first component part of the integral perforation representing the character being in one case in the top line of row perforations, and in the other case inseries of punch-selecting the bottom row, the same being caused by using the first top punch first in one case and the first bottom punch first in the other case.

It will be observed that the above explanation is only in reference to such keys that bear upon the frame R. It applies, however, to all the keys, with this exception, that such keys that are provided pass over the frame B, when they are dcpressed and donot operate the same, so that the mechanism connected with R is not operated, and the position of the bars 0 remain unchanged unless a hey is depressed that bears on the frame R.

We do not limit ourselves to the method shown of changing the position of the bars 0, as there are many other methods ofefl'ecting the same. Neither do we confine ourselves to the precise method of controlling the clutch It, as various other devices may be used without; departing from the general principle.
