PERFORATOR FOR AUTOMATIC TELEGRAPHS.

SP1;(LIIIFIGA'I.LION forming part of Letters Patent No. 2'70,774, dated January 16, 1883,

Application filed April 27, 1882. (Modell To all whom it may concern:

7 Be it known that I, THEODORE M. Foorrn, of'Brooklyn, in the county of Kings and State of New York, have invented a new anduseful Improvement; in Perforators; and I do hereby'declare'that the following is a full, clear, and exact description of the same.

My invention relates to perforators of that 7 class used to punch the fillets employed in air tomatic telegraphy, and which are operated wholly through keylevers. It is designed to punch a fillet in accordance with the plan or method used in my improved system set forth the receiving end also dots and dashes similar to those caused by the perforations.

To this end my invention consists, first, in the general organization of the machine, in which the main elements are three keys, a series of punches in one line, a fillet-moving mechanism, one of the three keys being in connection with and operating at each alternate depression a single punch, and after eachdepression advancing the fillet forward a single or 'dot space, a second key operating at each alternate depression two punches,and after each depression moving the fillet forward double the distance of the single or dot space, and a third key connected with or adapted to operate four punches, but operating them only when depressed next in order after that depression of either of the other keys, and which moves the fillet, but does not punch, said third key being also connected to the filletmoving mechanism in such a manner as to move the fillet four times the distance of the single or dot space. This organization is designed to make, in accordance with the'requirements of the-system above referred to, perforations adapted respectively to transmit impulses sufficient to cause a dot and a short dash, indicating the parts of the integral perforations which represent letters, and a longer group of perforations adapted to transmita continuous impulse, forming a space-dash between letters or words on the receiving-fillet. At the same time the keys, by alternate depressions, move the paper without punching a distance adapted to causea break sufficient to make the dot and dash which constitute the integral perforations representing letters, and also a space between letters and words-that is to say, one key operates, for example, by its first depression, a single punch, and upon its return moves the strip forward a space sufiicient to make a break in the line long enough to cause a dot at the receiving end. A second key operates two punches, making two holes in the fillet near enough to transmit an impulse adapted to cause a short dash at the receiving end and move the paper upon its return. a distance twice that of the key first named, which space causes a break that records a like dash. The third key, on its depression, punches a group of four holes, adapted to transmit a continuousimpulse, recording a long dash, and upon its return moves forward the fillet a distance equal to four times that of the first key, which quadrupled space forms a break, recording a like elongated dash. Further, each of the firstand second keys, while moving the fillet upon return from each depression, punches only alternately, whether one key be depressed successively or two be depressed alternately, so that in the formation of the integral perforations or the groups of perforations representing letters a dot-perforation may be followed by a dot-blank or by a dash blank, and a dash-perforation may be followed by a. dot-blank or a dash-blank. Further, if the third key, perforating four holes, be depressed after either of the others, it punches if the keylast moved has not punched, but moves the fillet its proper distance without punching if the preceding key has punched; but if upon any depression the four-punch key operates the punches upop other or repeated depressions immediately succeeding the first, it continues to punch, forming a continued line of close perforations adapted to transmit an impulse to record a'dash between sentences. 0n the other hand, if the four-punch key upon any depression moves the fillet Without punching, it continues so to do upon immediately- IOU resents a side elevation of the instrument from the right, and Fig. 5, Sheet 2, a like view from the left. Fig. 6, Sheet 3, represents a section on line 00 w of Fig. 1. Fig. 7, same sheet, is a rear view; Fig. 8, a detail of Fig. 7. Fig. 9,

Sheet 4, is a bottom view. Fig. 10, Sheet 5,

is a horizontal section on line y y of Fig. 6. Fig. 11, same sheet, represents details.

Referring to Fig. 1, punches are shown at 1., 2, 3, and 4. They move in'blocks 5 and 6, and are all retracted by a spring, 7, which passes in front of pins set in-the punches and projecting downward. The strip of paper passes through a guide, 9, on the right-hand side, between the block 6 and a die, 8, and thence around behind the feed-wheel '10 and forward between it and the pressure-roller 11. The

punches are operated by means of pushers 12,

13, and 14, the pusher 12 being movedindependently by the first key, (marked A,) pusher 13 by the second key, (marked 13,) and carrying with it the first pusher by means of a pin, 15, set in the pusher 13 and working in a slot, 16, of pusher 12, said slot being shown in Fig. 11, Sheet 5. The pusher 14 has a head broad enough to meet the punches 3 and 4. It is moved by the key 0, and carries with it both of the other pushers by means of the pin 15, before described, and the pin 17, set in pusher 14 andworking in a slot, 18, shown in Fig. 11, Sheet 5. The slots 16 and 18 permit the pushers to move independently upon their connecting-pins, or to be moved by them, so that they may be operated independently or together in the manner described. The pushers are moved by arms 19, 20, and 21. They are shown in Fig. 1, Sheet 1, and in Fig. 7, Sheet 3. These arms stand vertically in the rear part of the machine, being pivoted upon a rod, 22. The arm 19 is connected to a sleeve, 23, fixed to the end of the lever of key A. The arm 20 is fixed directly to the lever of key B. The arm 21 is fixed toa sleeve, 24, which is attached to the lever of key 0, each forming with its key-lever a bell crank-lever, and when its key is depressed is swung forward. The pushers are attached to the upper ends of their re-' spective arms by means of broad-headed pins passing through slots 25 in the rear ends of the pushers, these being necessary to permit the independent movement aforesaid. The key-levers are returned, after depression, by means of springs 26, as shown in Fig 9, Sheet 4,- and in Fig.6,Sheet 3. They bear upon 'pins set in the side of the levers.

The alternate vertical movement necessary to give alternate impulses to the punches'is directly effected by a bell-crank lever, D, pivoted at 27, as shown in Figs. 1 and 6. It is pivoted upon an arm, 28, on a standard set in the side of the frame. Thehorizontal end of it projects into the slot 29 of the pusher 12. The bell-crank is rocked by means of' a sinuous slot in a wheel, E, by means of a pin setin the lower end of the vertical arm of the bell-crank and projecting into the said slot. The wheel E is fixed upon the shaft 30, having its bearings in standards on the sides of the frame. Motion is im parted to this shaft th rough ratchetwheels 31 32, fixed thereto. The ratchet-wheel 31 receives motion from a push-pawl, 33, and

is retained by a catch-pawl, 34. The pawl 33 is pivoted upon the arm19, Figs. 6 and 7, Sheet 3. There are as many teeth in the ratchet-wheel 31 as there are points in the sinuous slotof the" wheel E, and the mechanism is so adjusted that when the arm is moved forward it turns the ratchet 31 so as to cause the periphery of the wheel E to move the distance equal to the space between the centers of the opposite successive projections of the sinuous slot. This, by means of the bell-crank lever, alternately lifts and depresses the pusher 12, and as the other pushers are connected by means of the pins 15 and 17, they rise and fall at the same time. The ratchet 31, however, communicates motion only from the key A. Motion from the municated by means of a push-pawl, 35, piv-' oted upon arm 20 and operating upon ratchet 32, also fixed to the shaft 30. The ratchet 32 has the same number of teeth as ratchet 31, and they are similarly set. It will be observed, therefore, that whether the pawl 33 be operated by the key A twice in succession, or whether it be operated once, followed-by depression of the key B and operation of the pawl 31, the action upon the bell-crank lever will be the same'-that is to say, it will, upon the first movement, move the pushers one-way, and upon the second, move them the other. The special office and action of the key O,h0W'- ever, requires a different construction of the parts which operate the bell-crank lever which lifts the pushers. To accomplish the resultrequired here-that is to say, to cause the key 0 to depress the pushers if moved next aftereither of the other keys has raised them, or raise them next after one of the other keys has depressed them, or to repeat, after succes sively depressed, its operation or non-operation upon the pushersI provide a third and spe cial form of pawl. It will be understood that the wheel E is held by the various pawls heretofore described in the position in which the has a plane face, as shown at 41, which, when the pawl is thrown backward by the spring 42, bears against the forward edge of the arm 21, by which means,,when the key 0 is de pressed and the arm 21 thereby thrown forward, it carriesforward the arm 38, with it the pawl 39, the latter moving the ratchet-wheel 32, and thereby the wheel E one notch. This oscillates the hell-crank lever and raises or lowers the pushers according to the position of the lower end of the vertical part of said hell-crank lever in the sinuous or zigzag slot at the time when the movement last named commenced-thatis to say,if the vertical arm of the bell-crank were thrown to the left and the pushers therefore down, when said movement commences movement caused by the arm 21 will advance the wheel-E one step and raise the pushers; but if the pushers were up at the commencement of said movement the movement would by like advancement of the wheelE one step throw them down; but the pawl 39 is also provided with a pin, 43, Figs. 1, 4,'and 6, Sheets 1, 2, and 3, projecting laterally from its free end in a direction opposite the projection 40. This pin, when the pawl 39 is thrown forward, comes in contact with the upper end of a spring-arm, 44. This springarm is provided with a tooth, which catches into a notch in the wheel 45 upon the sleeve, and prevents the sleeve with itsarm and pawl 39 from going backward. Thus while thearm 38 and pawl 39 are in this position repeated movements of the arm 21 do not operate the wheel to elevate or depress the pushers. In order to release this pawlfi'rom its position, it

.is only necessary to depress one of the other keys and by the pawls 33 or rotate the shaft 30. This causes the ratchet-wheel 32 to advance one step, and the arm 40 to ride up on the tooth next behind it, which leaves the pawl 39,- and by means ofthe pin 43 the springarm, out of the notch, and allows the spring 42 to draw the arm 38 back. A wheel, 45, Figs. 1 and 4, Sheets 1 and 2, is fixed on the sleeve 37,- and against its periphery a spur of the spring-arm 44 rests, holding said springarm back ready for connection with the pin 43. Light springs 46and 47 bear against the pawls 33 35, and another spring, 48, is-placed by the side of the arm 19, as shown in Fig. 7, fixed at the lower end, with the upper end bearing against a pin in the rear end of the pusher 12, as shown in Fig. 1. By this spring the pusher 12 is retracted after working, and with it the other two, through the pins 15 and 17.

It is essential to the operation of the machine that the movement of the fillet shall take place immediately upon the rise of the keys. To this end the depression of the keys is made to push back the pawl which operates the paper-moving roller 10, which pawl is operated directly'by a spring. This mechanism is operated by the arms 19, 20, and 21 coming in contact, when their respective keys are depressed, with the leve'r49. (Shown in Fig. 1 and fully in Fig. 10, Sheet 5. This lever is pivoted at 50, and is thrown back by a spring,

' 51,- upon the backward movement of the arms 19, 20, and 21. The lever 49 has a bent arm, 52, which is connected by a link, 53, to a lever, 54, pivoted on the shaft 55 of the wheel 10. Just above this lever is a ratchet-wheel, 56, held to the shaft by a set-screw. The lever 54 carries a pawl, 57, engaging with the teeth of the ratchet to rotate it. The ratchet is held by a stop-pawl, 5S.

It will be apparent from an inspection of Fig. 10, Sheet 5, that the position of the arms 19, 20, and 21 is such as to give a varied amountof movementto thelever 49 the amount increasing in the order specified for a given movement of the levers. The amount of move ment is precisely regulated by means ofa stopblock, 59. (Shown in Figs. 4, 6, and 10.) This block is provided with a notch, as shown in Fig. 4, above which is a plane face. As the block stands when not depressed by key B the notch is on line with the lever 49; but the block is connected to the lever of key B, and when that key is depressed the block is drawn down, so that the face above the notch is opposed to the movement of the lever 49 and limits its movement. When the key (3 is de-- pressed the lever 49 enters the notch, and thus has an enlarged though still limited movement. These movements give the amount of feed required tor the fillet by all the different perforations and spaces. In order that backward movement of the lever 49 may be arrested long enough to allow the punches first to be retracted from the paper,I provide a bell-crank lever, 60, pivoted at 61, and having a hook upon its end engaging with teeth ab c on the end of the lever 49. The arm 62 of the bellcrank lever is thrown forward by a spring, 63, to bring the lever into engagement with the teeth. The lever is thrown out of engagement by an arm, 6!, projecting upthrough a slotin the bed-plate. This arm is set in a block attached to the shaft 65 on the under side of the machine, Fig. 9, Sheet 4. The shaft 65 is provided with a frame, 66, Figs.5 and 9,the frame extendingacrorsunderihekey-levers,bymeans of which, wnen any one of the keys is depressed, frame 66 is rocked and the arm 64 is tipped forward, allowing the spring 63 to throw the lever into engagement with the teeth of lever 49. The movement is sutticient to take the arm 64 quite away from the arm 62, and the distance to which it is removed is such that upon its return, when the keys rise, it has to move a slight distance before acting upon the arm 62 to throw the bell-crank lever out of engagement with the lever 49. This gives sufficient time for the retraction ot' the punches from the paper before the paper is fed forward. Vthen key A is depressed lever 60 hooks over the tooth c, and'the return of lever 49 moves the wheel 10 a space which I have called the dot-space, which is also sutficient for a single perforation. lVhen key B is depressed the engagement is withthe tooth b,

IlO

and the retraction of the lever 49 moves the wheel 10 double this space. \Vhen key 0 is depressed engagement is with the tooth a, and the movement of the wheel 10 is four times this first space. Pressure-roller 11 on the arm 67 is made to bear against the wheel 10 by means of a spring, 68. The fillet passes through a slot, 69, at the front right-hand corner of the machine, being held down byalatch, 70. Thence it passes in front of the punches, behind the die 8, and around the roller 10, between it and pressure-roller 11.

The gutter 72 in front of the machine conducts away the disks of paper as they are punched. The pressure-roller is spread from the driving-roller by means of the cam '74, operated by means shown in Fig. 3. v The keys may be operated either by the direct application of the fingers, or by small rubber-faced strikers adapted to beheld in the hands; or they may be operated by a plunger moved by compressed air, or by any other suitable and well-known mechanism.

I have shown the key 0 operating the four punchesplaced atone side; but it may be placed in the middle equally as well without any material alteration of the parts, if the machine be intended-for those accustomed to that arrangement of the keys. This arrangement is shown in an application filed by me in the United States Patent Office on the 8th day of May, 1882, entitled Improvement in Pert'orators.

Having thus described my invention, what I claim is- 1. A perforator for telegraphic fillets having as its main elements a series of punches in one line, a fillet-moving mechanism operating upon the retraction of the punches a key-lever and an independent punch-pusher, and intermedi-. atemechanism between said pusher and the fillet-mover, wherebysa-id key-lever punches upon each alternate depression only and moves the fillet on each depression a dot-space; asecond key-lever and a second punch-pushing device, with intermediate mechanism between said second key-lever and the second pushing device and the fillet-mover, whereby the second lever operates two punches upon each alterna'e depression only, and operates the fillet-moving mechanism after each depression twice a dotspace; and a third key-lever,with a punch-pushing device, and intermediate mechanism between said third lever and the punch-pusher and fillet-mover, whereby the said third keylever is made to alternate in punching with either of the others, but not alone, and to movethe fi'llet with each depression four times the dot-space, all substantially as described.

2. In the described kind of perforator, a series ofpunches arranged in a singleline, punchpushers connected to each other and to the keylevers, so that one pusher may be moved alone or with the second and third, in combination with mechanism, connected also to the keylevers, for throwing thepushers into and out of line with the punches upon alternate depression of the keys, substantially as described.

3. In combination with the punches arranged in a single line, the pushers 12, 13, and 14, connected by the pins 15 and 17, working in slots in the arms of the key-levers, an arm for alternately elevating and depressing the pushers, and intermediate mechanism between said arm and the key-lever arms, whereby the position of the pushers is changed on each depression, substantially as described.

4. In the described form of perforator, aseries of punches in a single line, a pusher, 12, operated by the keyA through lever and arm 19, asecond pusher, 13, connected to the pusher 12, and operated by key B through lever and arm 20, a third pusher, 14, connected to pusher 13, and moved by key 0. through lever and arm 21, a guiding-arm to shift the pushers into and out of line with the punches, operated through a shaft, 30, a pawl-and-ratchet connection with the key-lever arms, an arm, 38, loose on shaft 39, carrying a pawl adapted to be moved by the arm 21 of key 0, in combination with a catch mechanism adapted to hold arm 38 in its advanced position until tripped by the depression of key A or B through the described mechanism, all as set forth.

5. In the described form of perforator, and in combination, key-levers pivoted at their rear ends, and having vertical arms 19, 20, and 21, springs for returning the key-levers after depression, pushers operated by the arms, punch es operated by the pushers, a shaft provided with a wheel operating thelever, which changes the direction of the pushers, and pawl-andratchet mechanism, whereby the arms cause the shaft to rotate step by step, substantially as described.
