4SPIECIIEIIGAJLION forming part of Letters Patent No. 270,213, dated January 9, 1883.

Application ined May 8,1882. (Modem .To au whom it may concern Be it know-n that I, THEoDoRE M. Foo'rE, ot' Brooklyn, in the county of Kings and State of' New York, have invented a new and useful Iinprovementin Perforators; andi do hereby declare that the following is a full, clear, and exact description ot' the saine.

My invention relates to perforators of that class which are adapted to punch fillets in two lines of perforations, such as are ordinarily used in the Foote t Randall system of telegraphy. As is wellknown,in this system the impulses required to form dots and dashes alternate in polarity between any two successive marks, and the record is made wholly by transmitted impulses.

The object of my invention is to provide a perforator which shall fullill all the requirements ot' that system with only three keys, and, further, to simplify the construction ofthe apparatusand to improve it in certainty of operation.

`In the leading features theinvention herein set forth is the same as that shown in an application filed by me in the United States Patent Office on the 27th day of April, 1882, and entitled improvement in perforators.

The preseiitinvention consistsin the organ-- ization ofthe machine to accomplish the pur-- pose stated, of improvements in details of construction and combination.

In the accompanying drawings, Figures 1 and 2 are substantially elevations of opposite sides ofthe machine. Figs. 3, 4, and 5 represent details of parts shown therein, allthese being on Sheet l. Fig. 6 on- Sheet 2 is a top view. Fig. 7 of,Sheet3 is a bottom view. Figs. 8, 9, and 10, Sh'eetfl, are views of details. Fig.

11 is a section otFig. 9, and Fig. 12 detail view.

In these drawings a convenient base of the inacliineis shown at D dd, in the top 'and sides` of which are bearings and supports for the [iXed and moving parts.

The three key-levers are marked respectively A, B, and O. They are all pivoted at their rear ends upon a shaft, 22. The lever A is fixed to a sleeve, `23, on the opposite end of which is a vertical arm, 19. The lever C is dnectly connected toor formed with a like arm, 2l. Lever B is fixed to a sleeve on the shaft 22, beneath the sleeve '24, and to the inner sleeve is attached a like vertical arm, 20, these vertical arms forming, with their respectfive key -1evers, practically bell -cranlr` levers, and their upper ends are tipped forward on depression ofthe key-levers. To their upper ends are connected pushers 12, 13, and 14, 12 and 13 by means of slotted ends hearing upon headed pins in the. arms, and 14 by a simple pin-connection. These three pushers are connected to. each other by a pin, 15, in pusher 13 entering a slot in pusher 12, and by a pin. 17, in pusher 14 enteringa slot in pusher 13, so that the pusher 12 may be advanced alone. Pusher 13 niaycarry pusher 12 with it by reason ofthe pin being normally in the forward end of the slot, and pusher 14 may carry both pushers with it for like reason. The rear slots in the pushers allow movement independently of their moving arms, and they are carried back by means ot' a spring, 48. (Shown in Fig. 2.) Thearinsareheld back and the keys are kept normally raised by means of springs 26 bearing underneath pins set in the sides ot' the key-levers, as shown in Figs. 2 and 7. In front ofthe pushers are two rows of punches. (Shown in`Figs. 1, 2, and 6, and marked in order, 12 3 4.) These are of ordinary construction, playing freely through guide-blocks into a die, and 'being retracted by springs, as shown in Fig. 6. Punches 1 and 2 are capable of independent act-ion; but punches 3 and 4 are connected to each other by a piu, so that they move together. The lower row is a duplicate of the upper. rllhe system for which it is intended and the principle of the machine require that the upper and lower punch, l, should act alternately ini dependently of the others, that the upper and lower punches, 1 and 2, should act together, alternating with their fellows in the lower line, butall fourof the punches in each row sliculd be capable ot' acting together by means ot'a single key, O; but each set must Valternate in action with the singleor double punch of the opposite row, and the set of fours must not .alternate with each other-that to say, it' either key Aor B be depressed, and thereby operate a punch or punches in the lower line, and then key G be IOO depressed, it will operateall four `punches in the upper line, and if depressed again, without an intermediate depression of either of the other keys, it will punch again in the same line,

land will not, so to speak, alternate with itself like the other keys. This is for the obvious purpose of doubling the space-dash between letters formed by the four punches, so as tov form a dash between words. This alternation is accomplished by {much-shifting mechanism in priticiple like that shown in my application aforesaid. This punch-shifting mechanisinis, tiist, a lever, a, Figs. 2 and 6, which has two bent arms, adapted to bear upon the notchedl periphery of a wheel, E, on a shaft, 30. The arms are so related to the wheel that the forward one tides upon a tooth while the rear is in the recess between two teeth, as shown in Fig. 2, and then tlie'forward end of the lever is thrown up and all the pushers, by reason of their aforesaid piti connections, are elevated in line with the upper row of punches. A movement of the wheel E one step i'everses the position of the arms of lever a in respect to the wheel E and depresses the forward end of said lever, bringing all the pusliers down in liiie with the lower lille of punches, and this shifting of the pusliers vertically must happen every time the wheel E moves one step. The wheel 'E receives this step-by-step movement by means of' a ratchet-Wheel, b, iiXed on a sleeve with wheel E. The pawl c, Fig. 3, ot' this ratchet is connected to the arm 20 by means of a slotted end similar to that ofthe pushers 12 and 13. lt has a pin, e. extending acrossjust in front of arms 19 atid 20, so that either ot' these arms, when tipped-forward, will carry the pawl with it and move the wheel Fi one step, but the conditions under which the arm 2l opera-tes are substantially the saine, so far as it relates to the working ofthe pushers, as. those described in my aforesaid application, and it isprovided with a similar mechanism. (Shown in Figs. l and 6.) An arm, 38, is fixed on the shaft 30, its rear end being prolonged tobear against the arm 2l. A spring, 42, attached to its paWl draws it back into connection with the arm, the pawl havingl an arm, 40, engaging with the teeth of the ratchet b. A pin, 43, on the other side of the pawl, opposite the artii 40, is adapted to come in contact with the upper end of a spring-arm, 44, when the paWl39 is thrown forward. Upon the sleeve or hub of the arm 3S is a wheel, 37, having a notch which receives a spur upon the spring-arm, by means of which, when the arm has been thrown forward, the sleeve or hub is held and the arm prevented from returning until the spur upon the spring-arm is released from the notch in the wheel. The arrangement is such that the pin 43 comes into contact with the upper end ofthe spring-arm when the spur is in the notch. At the same time the arm opposite the pin 43 rests in the space between the teeth of its ratchet-wheel. This connection just described continues through repeated movements ofthe key C and until one of the other keys is operated. Either of the other keys being operated, its proper pawl turns the shaft, and with it advances thev ratchet-wheel one tooth. As the tooth advances the arm 40 rides upon it, which lifts the pawl, and through the pin 43 raises the spring-arm, with its spur, from the notch, thereby releasing the sleeve aiid allowing the pawl 39 to be drawn back by its spring into contact with the arm 2l by key C. It will be apparent, therefore, that the key C cannot operate the devices which raise or lower the pushers twiceiii succession. Therefore, if the key C, upon depression, operate through the pushei'stlie upper row of pushes, an immediate repetition of this movement will punch the same row; but it', after the depression ot' the key C, another key be depressed, then bythe release of the pa-wl 39 and its arm these latter will be in position to be operated again by the arm 2l of the key C, Wliereby the pusher-shifting devices are brought itito operation, and alterna-tion in the operation otv the punches is effected.

l now proceed to describe the devices and combinations for moving the iillet. The plan requires that key A should move the iillet one` space, sufficient for a single dot, that the key B should cause it to Amove twice that distance, and key C tour times the distance. Further, it is requisite that the movement of the lilletmoving mechanism should take place after the depression-of the key-levers, or rather after they begin to rise. and that a stitlicient time should elapse after the return movement of the keys and before the -iillet-moving mechanism operates to allow the punch-springs to withdraw the punches from the tillet. To fultill these conditions l pivot upon the bed-plate a lever, 49, which a spring, 51,'teiids constantly to press forward. A link, 53, connects this lever to an arm, 54, carrying the pawl 57, said arm being pivoted upon the shaft 55, which carries the ratchet 56 and the drive-wheel 10. The forward movement of the pawl and wheel is stopped by a post, S0. It will be understood', more particularly by reference to Fie'. 8, that the forward movement of the paper is caused bythe spring 5l. The backward movement ofthe lever 49 for the purpose of giving the pawl 57 a new hold upon the ratchet is effected by au arm, 64, which is set on a rock shalt, 81, Figs. l and 2, underneath the plate. From this rock-shaft arms 83, 84, and 85, Figs. 7 and 12, extend along toward the rear underneath the key-levers. They differ in length according to the amount of backward movenient each key-lever isrequired to give to the rock-shaft and lever 49-that is to say, arm 8,5 extends farthest to the rear 'and hears upon a part `of the lever A where it receives least m0- tion; arm 83 is shorter and bears upon lever B where it receives more motion; arm 84 is the shortest and receives most motion,all from substantially the same amount ot' movement of the key-levers. These movements are determined with sufficient accuracy by the arrangement ofthe arms 83, 84, and 85 to give an eX- act amount of movement to the varm 4to fulfill the required conditions-that is to say, arm

85 will push back lthe pawl 57 over lone notch of the ratchet; 56, arm 83 over two notches, and arm 84 over four notches, giving corresponding forward movementl through the invariable action of the spring 5l; but in order that this forward movement may not take place im mediately upon the beginning of the return movement of the key-levers, and before the punches have retreated from the paper, I provide a tem- 'porary stop consisting of a pawl, 60, taking into notches w y z. Itis drawn in by a spring, 86, attached to an arm, 87, of the pawl 60. The Ynotches correspond in position to the three did'erent movements heretofore described of the arm 64. The arm 87 projects slightly in front of the arm 64, and is left by the lever in its backward movement against the lever 49, 'after the pawlhas engaged with a tooth; but when any key has moved part of the way on its rise, and the lever 64 is on its return,it

strikes against the arm 87 and throws the A paw'l out Vof connection with the notch, thus allowing the spring` 51 to give the forward movement to the tillet. A pressure-roller, 11, bears against the llet, asin my aforesaid application. 4

VHaving thus described my invention, what I-claim is 1. In a perforator, two series of punches arranged to punch in two lines, a pusher connected with one key, and thereby operating upon a punch ot'` the upper or lower series, a shifting mechanism connected to said key-le ver and operated thereby forshifting the pushers on successive depressions of the said keylever alternately from one series to the other, and the fillet-moving mechanism set in motion by the said key-lever and acting upon its rise, a second pusher connected to a second key-lever and to the first pusher, and a shifting mechanism connected also to said key-lever, whereby both pushers are made to operiate on their proper punches in the upper and lower-series alternately upon successive depressions ofthe said second key-lever, andconnection Abetween said fillet-moving mechanism and said second keylever, whereby the iillet sion of said third key-lever will operate all four times the distance of the movement caused l by the first key-lever, all these parts being organized in the machine substantially asdescribed.

2. Inthedescribed machine, the pusher-shifting mechanismconsisiing of the lever a, wheel E, ratchet b, and the pawl c, substantially as described.

3.
