MEANS FOR PRODUCING TELEGRAPHIGITRANSMITTING-TAPES. i I i No. 889,787. Specification of Letters Patent.

Application filed January 5, 1905. Serial No. 239,802.

Patented June 2, 1908.

To all whom it may concern:

Be it known that I, ISIDOR KITSEE, of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Means for Producing Telegraphic Transmitting-T apes of which the following is a specification.

My invention relates to an improvement in means for producing telegraphic transmitting tapes. I

In Letters Patent No. 777,259, dated December 13th, 1904,1have described amethod, with the aid of which true reversals may be transmitted over conducting lines, and which method has more special reference to submarine telegraphy.

In practice, the use of a double key for the transmission of the impulses in accordance with my code has some drawbacks, and it is the aim ofmy invention to produce a transmitting tape with the aid of a perforator in a manner so that intelligence may be electrically transmitted in accordance with the above named method automatically with the aid of this tape.

The underlying principle of the method as described in the above referred to Letters Patent consists therein, that first,all impulses are of an alike duration and intensity; second,after an impulse of one polarity an im ulse of opposite polarity must always fol ow; third, the different values between dots and dashes are indicated thereby, that a dot consists of one impulse and a dash of two impulses in quick succession. It is therefore only the difference in time la sing between the different impulses which wi 1 enable the operator at the receiving end to distinguish between the symbol denoting a dot and the symbol denoting a dash. To produce a tape of a character so that this method should be carried out therewith, it is necessary to have recourse to a special punching device and in the drawing I have illustrated a preferred form for such device, it being obvious that the details of same may be varied to suit requirements without departing from the scope of my invention.

In these drawings, Figure 1 is an isometric view of the device embodying my invention. Fig. 2 is a diagrammatic view illustrating the electrical connection of the batteries, line and ground.

In Fig. 1, B is the tape adapted to be run between the friction cylinders A and adapted to pass through the punch-blocks L and I.

b are the perforations made in the tape B.

C is a friction roller in juxtaposition to a second friction roller D. The friction roller 0 is centered on and secured to the shaft C and the friction roller D is centered on and secured to the shaft D. To this shaft D are also secured, so as to move in unison with the friction roller D, the ratchet-wheel D and the ratchet-wheel D; the ratchetwheel D provided with the teeth (1 and the ratchet-wheel D provided with the teeth (1. Both the teeth d and the teeth d correspond in number. D is a ratchet engaging in the teeth 01 for the purpose of preventing a backward movement of the friction roller D.

E is a key or lever provided with the spring 6 adapted to hold the key-arm in engagement with one or the other of the teeth d; this key E is fulcrumed on the pin a E is a key or lever provided with the spring 6 adapted to hold its key-arm in engagement with one or the other of the teeth d this key E is fulcrumed on the pin 6 E is a key or lever provided with the spring 6 adapted to hold its key-arm in engagement with one or the other of the teeth (1 this key E is also fulcrumed on the pin 6 The key 6 is further provided with the projection e and also with the spring 6 which spring holds the key in contact with the stop-block J. F

is a lever fulcrumed on the pin f and provided with the spring f which spring through the cross-arm or bar F holds the keys E and E in contact with the block J. This lever F is also provided with the arm- F which arm, by means of the spring f is held in contact with the teeth h of the punch-actuating means II. This means H is in the form of a wheel and is secured to the shaft H A number of protrudences 7L2 and.

h are placed on alternate sides of the face of the wheel H, the protrudences 7L2 being on one side and the protrudences h on the other side, this for the purpose of actuating the punches G and G alternately, as willlater on be more fully described. The.number of teeth It corresponds to-the combined number of protrudences k and h The punch Gris provided with the spring g and is held in position by the punch-block L. The punch G is provided with the spring g and is held in position also by the punch-block L. K is a stop-block which regulates the movement of the lever F and also the movement of the key E through its projection e.

In Fig. 2, B is the tape and b are the perforations, which perforations here form the letters, G, O, O, D, or the word Good, according to my improved code. M is the conducting roller; m the brush connecting the same electrically to the line. N and P are the brushes connected with the batteries l and 19 respectively. Q, Q, are -the grounds. The arrow shows the direction the tape is traveling in.

Through the pressing of the key E, by reason of mechanical construction and position of shaft 6 the key E will raise one tooth d on the ratchet-wheel D Simultaneously with this-movement, the pressing of the lever E results in the pressing downwards of the lever F which results therein that the arm F will press against one or the other of the teeth h and will force the same upwards to the space of one tooth. This lever F is stop ed in its downward movement by the block K which allows the lever F only to move one tooth h By reason of mechanical construction, the turning of the wheel H one tooth h causes one of the raised portions h or h to move one of the punches G or G which punch passes through the tape B into the block I, thereby causing a perforation b to be made in said tape. These punches G and G operate alternately at all times, whether actuated by key E or E and cause the holes I) to be made on alternate sides of the tape B.

After pressing the key E till it causes the lever F to strike the sto -block K, the same should be released; the ever F being pulled downwards by the spring f will cause the key E to return to its position; on the other end, the arm F will return to position or one tooth 7L1 lower and will be held in contact with that tooth by means of the spring When the lever F causes the key E to move upward to its former position, key E being fulcrumed at 6 causes the end that is engaged in the teeth d of the ratchet-wheel D to move downward a distance of one tooth, thereby causing the friction wheel or roller D to move the space of one tooth and with the aid of this friction roller and the adjoining friction roller C, causes the tape B to be moved a predetermined space, which predetermined space will in the later using of thistape as a transmitting tape be equal to the duration of a half-time unit. Key E operates similarly to key E except by means of the pin or fulcrum e the lever E moves a distance of two teeth (Z causing a space of tape twice as great to pass over the block L, thereby causing twice as much blank tape to remain between the perforation last made and the one to follow, which predetermined space will in the later using of this tape as a transmitting tape be equal to the duration of one whole time-unit. Key E is simply a spacer and does not actuate the punches G and G By ressing key E the same strikes the bloc K and by mechanical construction the lever end moves two teeth d thereby causing the same amount of tape to pass over the block L as is caused by the key E These three keys, E, E and E give the Mowing: First,key E gives a perforation and a short space or a half-time unit following second,key E gives a perforation and a long space or whole time-unit following; and third,key E gives a corresponding long space to that of key E but without any perforation at all,

In the Letters Patent above referred to, I have, for the sake of clearer understanding, given the usual Morse code in conjunction with my improved code for the word Good which is written as follows Morse,

Cable code, Improved code,

In accordance with my improved code, the symbols to be transmitted would be as follows z-two impulses in quick succession to denote the first dash and two impulses in quick succession to denote the second dash and one impulse to denote the dot in the letter G. To perforate a tape for the transmission of the letter G, the operator has to strike first the key E to make the first perforation of the first dash with the attending short space; then the key F to make the second perforation of the first dash with its attending double space; then the key E again to make the first perforation for the second dash with its attending short space, then the key E to make the second perforation of the second dash with its attending double space; then the key E to make the dot with its attending double spaceall this for the first letter G. After this letter is perforated complete, then the operator should strike the key E to give an additional double space without any perforations. To produce the first letter O, which is composed of two dots, he strikes the key E twice which gives two perforations, each followed by a double space. He then strikes again the key E which gives the required double space without perforations. To produce the second letter 0, he strikes the key E twice which gives, as before stated, two perforations, each followed by a double space and he then again strikes the key E for the double space without perforations. To produce the letter D, which consists, as above stated, of a dash and two dots, the operator strikes first the key E to produce the first impulse and a short space and then the key E to produce the second impulse of the dash with a double space following, then he strikes the key E twice to pro- 'duce the two perforations for the two dots space key E twice so as to give twice as I much space between words as between letters.

In the drawing the tape B is perforated so as to produce the letters .G O O D. In other words, to produce a dash, it is necessary to strike first the key E and then the key E and to produce a dot it is only necessary to strike the key E and to produce an extra space it is only necessary to strike the key E I am aware that to-day the Continental Morse code is used on the cable, and the grouping of the various symbols is different from the American Morse, but I have taken the American Morse as the standardand it is easy for persons versed in the art to apply the principle to the Continental.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is In a device of the class described, three keys, means for one key to move a tape a predetermined space,means for the second key to move a tape a predetermined longer space, means for the third key to select the space for the other two keys and'means for the first named two keys to punch holes in said ta e, the third key provlded with means to se ect the punch to be operated.

In testimony whereof, I hereby sign my name in the presence of two subscribing witnesses, this twentieth day of December, A. D. 1904.

ISIDOR KITSEE.
