IMPROVEMENT IN APPARATUS FOR PERFORATlNG PAPER FOR TELEGRAPHIC USE.
Specification forming part of Letters Patent No. 132,456, dated October 22, 1872.
To all whom it may concern:
Be it known that I, THOMAS A; EDISON, of Newark, in the county of Essex and State of New Jersey, have invented an Improvement in Telegraphic Perforating-Machines, and the followingis declared to be a correct description of the said invention.
The strip of paper is perforated by this machine for use in transmitting telegraphic messages. The machine is made with keys that perforate either a single dot or three openings to form a dash, one of the three openings being larger than the others so as to produce a longer pulsation. The paper is fed the proper distance each perforation, and word-spaces, pauses, and sentence-spaces are produced by keys, and these keys are arranged in a small compass, and the instrumentis compact, cheap, and adapted to local offices or to individual use.
In the drawing, Figure l is a vertical section centrally of the machine and in line with the strip of paper; Fig. 2 is an elevation of the spacing-bars for words and sentences; Fig. 3 is an elevation of the spacing-bars for the letters and pauses Fig. 4 is a sectional plan at the plane of the paper; and Fig. 5 shows a piece of the perforated paper.
The bed a carries the standards I) c and frame 01. The die a is made with three openings, as in Fig. 4, for the three punches 2 3 4 that are raised by springs and depressed by the keylevcr f so as to punch the three holes at once, or when the key-lever g is depressed only the punch 4 is moved. In Fig. 1 it will be seen that the lever f, acting on the upper end of 2, carries that down, and by the arm 5 and pin 6 the punches 3 and 4 are also moved, but the pin 6 being below the arm 5 the punch 4 can be moved down separately. The perforation from the punches 2, 3, and 4 represents a dash, and in consequence of the punch 2 being the largest it removes sufficient paper to insure a paper-feeding mechanism is operated so that as the key is raised the feed takes place sufficiently to produce the required space between one letter and the next. The paperv h passes roller 1.
abovethe die e and through the slotted standard 1) between the feed-roller k and holding- The roller is is made with the ratchetteeth 8 in the middle, and m is the stop-pawl; n, the actuating-pawl on the lever 10; and o is the stop or blocking pawl on the lever 10 taking the second range of reverse ratchet-teeth. The lever 19 has its fulcrum at 10, and receives more or less vibration according to the amount that the paper is to be fed. The yoke q and springs r serve to raise the lever 19 to its full height, as determined by the stops 11 on the rods 12, and these rods 12 extend to the key s that gives motion to the lever 1) sufficient to space off between one Word and the next, as at a pause. The movement of the lever 19 is arrested by the notched slide 15, see Fig. 3, and this slide it is moved endwise to bring a deeper notch below the lever 10 and allow greater motion when the dash key-lever f is depressed, because the pin 15 upon the slide-rod 16 running down the incline 17 on t moves the same endwise against the action of the spring 18, when the said key-lever f is struck. When the dot key-lever g is struck the slide 20 moves the lever 10 and feeds the paper the same distance as when the space-key s is depressed. The
slide a, with a knob at its upper end, has a movement limited by the stop 21 and by the pin 24, moves the lever 1 and paper only a short distance, suficient to separate one Word from another, but the slide o with its pin 23 acting upon the incline 17, and also upon the yoke q of the lever p, depresses the latter to its full extent and feeds the paper a distance to denote the end of a sentence. In case the lever 9 should be depressed its full extent and it is desired to shorten the length of paperfeed the pawl n is lifted out of the ratchetv teeth 8 by the swinging finger and pin .70 that is actuated by the slide and key 20, so that as the lever 0 rises the pawl will go forward and three punches will be actuated by one key and only one by the other key, as set forth.
3. A feeding-roller actuated by a lever and pawl in combination with the perforatingpunches and keys, and intervening mechanism for regulating the movement of the lever in proportion to the length of feed-movement required for the paper.
4. The notched slide t in combination with the lever 19 and keys for spacing the distance between the perforations, substantially as set forth.
5. The finger w actuated by the key w in combination with the pawl n and paper-feeding lever 11, substantially as set forth.
Signed by me this 15th day of March, 1872.
