Application filed October 29, 1902i. Serial No. 129,232. (No model.)

To all whom t may concern,.-

zen of the French Republic, residing at Clermont-Ferrand, in the Republic of France, have invented certain new and useful Improvements in or Relating to Machines for Producing Perforated Strips for Gomposing or Like Machines, of which 'the following is a specification.

lThe present invention relates to a machine for perforating strips of paperin which groups or columns of perforations dilfering in the number` and disposition of the perforations represent the lettersof the alphabet or other characters, the perforated strips being destined for actuating or controlling automatic composing or like machines.

An essential feature of the improved'machine consists in the strips being not only provided with groups or columns of perforations, but having also added to each vgroup of perforations the printed'mark of the letter or character represented by each group, where'- by the verification or correction of the proof during the composing is greatly facilitated.

In the accompanying drawings, Figure 1 is a rear elevation and partly in longitudinal vertical section of amachine according to`t`his invention. Fig. 2 is a plan View and partial horizontal section on the line A B C of Fig. 1. Fig. 3 is a side elevation and partial sec# tional view on the line C D of Fig. 1^.- Fig. 4 is a partial front view. Fig. 5 shows a portion of a perforated strip produced by the machine, and Fig. 6 illustrates a modified constructional form of the punching device.

The machine rests upon a bottom plate l, to which the different supporting parts are attached. Four of these supports, preferably in the form of posts 2, carry a table or plate 3, on which two double electromagnets On the plate 3 and between the electromagnets 4 there is arranged a standard 5, to which is pivoted at 6 a balance-lever 7, carrying at its extremities hooks 8,V provided with set-screws 9, the object of which will hereinafter be described. To both arms of the balance-lever 7 are linked connecting-rods 10, t0 the middle part of which are'pivotally connected levers 11, revolubly mounted atv 12 in supports or standards 13, mounted on the plate 3, and provided at their free ends with toothed segments 14, engaging one on either side of a common pinion 15, revolubly mounted at 16 in the standard 5 and in another standard 17, fixed to the plate 3.

The vshaft 16 of the pinion 15 carries a disk 18, preferably made of insulating material, the circumference of which is'provided with a copper flange 19,V on the circumference of which are arranged the different characters, letters, or other typographical signs.

Between its axis of oscillation 6 and the 4connecting-Irods 10 the balance-lever 7 carries transverse arms 20, to which 'are fastened the extremities of armatures 21, the middle portions of which are provided with energizing-coils. l the upper poles of the electromagnets 4 4, and the coils of the armatures are in circuit with the coils ofthe corresponding electromagnets.

At both'sides of the plate 3 standards 22 are fixed to-the bottom plate l, to whichbrackets 26 and 27, carrying the supports 28 and29 for two other series of vertical andV horizontal electromagnets 24, arranged in a These armatures coperate with l similar manner to the magnets 24 just reits corresponding elect'romagnety 24. Some of the levers 32 therefore carry their larmatures on their horizontal arms, while others have them iixed to their lower vertical arms. The electromagnets are arranged in two rows on each side, and the two rows are so dis- ICC placed or break joint with regard to one another that the armature of a lever actuated by an electromagnet in the more remote row will not interfere or be interfered with by the adjacent electromagnet in the inner row. This arrangement enables a comparatively large number of independently operating electromagnets to be arranged in a given space. The levers 32 are kept at equal distances apart by means of insulating-disks mounted on the axle 3l.

Though alternately the horizontal and the lower vertical arms of the levers 32 are used as support-s for the armatures, each lever 32 is, nevertheless, provided with three arms, in order to obtain a better balance, the horizontal arms serving to return the levers to their initial positions when the current is cut off. If desired, springs could be used for the latter purpose. In their initial positions the lower arms 32lie against a cross-rod 32, iixed to the support 30.

Upon the bar 23, beyond each end of the balance-lever 7, are arranged bearings 34, carrying hinged to them the arms of stirrups or a frame 35, connected to a transverse bar 3G, arranged above the upper ends of the vertical arms of the levers The middle portion of the frame-bar 35, opposite to the har 36, engages between a set-screw 9, carried by the balance-lever 7, and a hook 8 thereon, so that this frame or forked lever participates in the oscillating movement of the balance-lever 7, the necessary free space or play between the moving and the driven part being obtained by adjusting the setscrew 9.

Each bar 3G carries a series of adjustable screws 37, arranged in two rows and equal in number to the levers 32. The lower ends of these screws 37 are arranged at different heights above their corresponding levers 32, the distance between the lower end of each screw and the upper end of its corresponding lever 32 being adjustable. The upper end of each lever is cut out or otherwise shaped in such manner that the screw 37 will not come in contact with the corresponding lever when the bar 3b' is moved by the balance-lever 7 unless the lever 32 has been acted upon by its corresponding electromagnet 24. The lever 32 when operated by its electromagnet comes opposite the corresponding screw 37 and acts as a stop to the bar 36, determining therebyihe amountof movement of the balance-lever 7.

All the screws 37 being arranged at different heights from the upper ends of the corresponding levers, each lever 32 when brought into action by its electromagnet will determine a different oscillation of the balancelever 7. These oscillationsof different angles are transmitted through connecting-rods 10, levers 1l, and the toothed segments 14 to the pinion 15, which in turn rotates the disk 18 to a corresponding extent, which is therefore determined by the amplitude of the oscillation of one or other of the bars 35.

The mechanism connecting the balance-lever 7 to the segments 14 constitutes a kind of linked parallelogram, both segments acting at the same time, so that the pinion 15 may be rotated in one direction or the other, according as the electromagnet 24 in action is situated on the left-hand or on the right-hand side of the balance-lever 7.

Springs 38 of suitable strength are fixed to blocks of insulating material and operate upon the lower ends of the connecting-rods 1Q to return the balance-lever 7 to its initial horizontal position after each oscillation. The free end of each spring 38 presses against a set-screw 39, so that by suitably adjusting the screws the initial position of the balancelever 7 may be made exactly horizontal. At the end of each rotatory movement of the disk 18 the paper strip is perforated and then advanced. For this purpose the disk 18 is provided on its exterior circumference corresponding to the characters or signs engraved upon the ring 19 with a certain number of holes 40, which are arranged in this case in seven circumferential rows. A corresponding number of punches 41, formed on the extremities of levers 42, are arranged and are adapted to enter these holes. The levers 42, the number of which is here seven, in correspondence with the seven rows of holes upon the disk 18, are mounted on shaft 43, carried by a bracket 44, secured to the bottom plate 1. Each lever 42 is formed on its boss or hub with a projection or stop 45, abutting against a bar 46, fixed to the bracket 44 and maintaining all the levers 42 in a horizontal position. y

The extremities of the levers 42 are provided on their under sides with recesses 47, constituting matrices, into which enter the pointed ends 4S of levers 49, loosely mounted upon a common shaft 50, fixed to the bracket 44, and corresponding in number and position with the levers 42. The levers 49 are also formed with projections 5l on the hubs resting against a bar 52, and thus serving to maintain the levers in a horizontal position when the levers are not acted upon.

The strip 53 to be perforated passes between the two rows of levers 42 and 49.

Fig. 6 illustrates a modified construction of the punching mechanism, the lever 42 heilig provided instead of the matrix with a point 83, coperatingwith a matrix S4, carried by lever 43. The s ection of this matrix is preferably enlarged toward the lower end. The modified construction of the punching mechanism facilitates the removal of the stampedout bits of paper.

Transversely and underneath the levers 45) there is arranged a hammer 55, formed on the extremity of a lever 54, pivotcd to the bracket 44. The surface of this hammer is coated, as may be best seen in Fig. 4, with india-rubber.

ICO

, ter with the driving-roller 76.

The hammer is provided with a lateral extension 56, also coated with india-rubber, adapted to come into contact with the periphery of the copper ring 19 of the disk 18 when the hammer is raised. The under side of the hammer 55 rests upon the extremity of a lever 57, pivoted at 58 tothe bottom plate 1, the other extremity of the lever 57 being provided with a rounded head 59, against which bears on each side one of thearms 60 of angle-levers pivoted Vto the bottom plate, the vertical arms 61 of which pass through and project above the plate 3 and are acted upon by transverse bars 62, oscillating in horizontal planes. The bars 62 carry attached to them electromagnets 63, coperating with the lower poles of the electromagnets 4. AA spring 64, bearing against the under side of the head 59 ot' the lever 57, causes the lever 61 and the bar 62 to resume their initial positions after the current has been interrupted.

As the object of the different parts above described is to record upon a strip of -paper the matter to be composed by'means of perforations and impressions, it is necessary to move the strip after each record corresponding to a character in order to enable another record to be made. This feeding movement of the strip is brought about in the following manner: The lever 57 carries at its extremity adjacent to the hammer 55 a pin or projection 65, which when the hammer 55 returns to its initial position bears against an elastic spring 66 and depresses the spring into contact with another spring 67, whereby a circuit including a d ouble electromagnet 68 is closed. This electromagnet attracts an armature 69 at the extremity of a lever 70, pivoted to a bracket 71 and carrying at its opposite end a spring-pawl 72. A spring 74 tends always to return the lever to its initial position'. Upon each rising movement of the pawl end of the lever 70 the pawl 72 operates a ratchet-wheel 73, the shaft of which is mounted in bearings 75 and is integral with a roller 76, over which the paper strip- 53 passes. A counter-roller 77, bearing against the strip, insures a perfect contact of thelat- A set-screw 78 serves for adjusting the angle of oscillation of the lever 70, and consequently the number of teeth by which the pawl 72 moves the ratchet-wheel, so that the feeding movement eected by the rollers 76 and 77 may be regulated as desired.

In order to obtain simultaneously with the perforations a printedmark of the character upon the edge of the strip, two inking-rollers 79 are placed on opposite sides of the metallic ring' 19 and are mounted on pivoted levers 80, provided with counterweights 81 orappropriate springs.

The series of electromagnets 24 of the maboard or any other suitable apparatus-such as, for instance, is described in my former application, Serial No.69,950,' Iiled July 27, 1901.

The electrical connection of the various coils of the apparatus is as follows: One end of each coil 24 is connected to the corresponding part of the electric keyboard or other device-as, for instance, described in my said patent. The other ends of all the coils 24 situated on the same side of the' apparatus are connected to a single flexible wire leading to the two coils 4, arranged on the side of the machine opposite to the coils 24Vin question. In the same manner the opposite lcoils 24 are connected with the two coils 4, situated on the other side of the balance-lever 7. The return-wires of the coils 4are connected to a common return-conductor. The coils of the armature 21 and the electromagnets 63, fixed to the bar 62, are contained in the same circuit as the`electromagnets 4, so that the current energizing the stoppingelectromagnets 24 energizes at the same time the armature 21 and the coil 63. It is obvious from the foregoing description thatwhen the operator touches with the stylus one of the blocks of the board or operates one of the keys of the keyboard an electric current is sent into the corresponding electromagnet 24, which attracts the armature 33, situated in front of it, and thus places the upper end of the corresponding lever 32 in the part of the.

Thecurrentpassingatthe Y transverse bar 36. same time through the two coils 4, situated on the other side of the balance-lever 7, will attract the corresponding armature 21, and thus oscillate the balance-lever and move the transverse bar 36 in opposite directions. That one of the bars 36 which is situated on the same side as the lever 32 broughtinto action presses against this lever with its corresponding screw 37 and determines thereby the amount of movement imparted to the balance-lever 7, which movement, as above described, is transmitted to the disk 18, as shown in Fig. 4.

The double electromagnet 4 through which the current iows attracts by the lower end of its core the bar 62, carrying the coils 63, whereupon the lever 57 is moved through the intermediary angle-lever 61. This movement brings about an instantaneousupward movement of the hammer 55, which liftsall the points 84 against the strip 53. Those of the IOO IIC

points which are stopped in their upward movement by the matrices 47 will `perforate the strip 53, so that the number and the position ofthe perforations are determined by the levers which are stopped in their upward electromagnets 24, 4, 21, and 63, the disk being stopped in the proper position by the contact of the balance-lever with the leveri32,

corresponding to the character chosen, before the hammer 55 has accomplished its movement. It is obvious, however, that instead of the disk and the hammer moving simultaneously a successive movement of the two parts in question could be easily obtained, for instance, by arranging a contact device upon the bar 62,by which the circuit ofan electromagnet arranged under the extremity 59 of the lever 57 would be closed. It has been already mentioned above that the disk 18 is provided on its whole periphery with a number of holes arranged in seven circular rows corresponding with the seven levers 42. If, for instance, the disk 18 presents at the end of its rotatory movement four holes lying in the same line transversely to the seven rows, these four holes coincide with the points of the levers 412 and enable, therefore, four of these levers to move upward, while the other three levers are maintained in position and serve as matrices for the punches 48, so that three holes will be made in the strip transversely to the length of the strip. Besides the action of the hammer 55 on the levers 42 and 49 a mark or record of the character corresponding with the group of perforations will be obtained by the coperation of the projection 5G with the ring 19 of the disk 18. It will be easily understood that by the arrangement of different groups of perforations containing different numbers of holes arranged in a diierent way a great number of different characters may be obtained. The strips thus perforated by means of the machine above described may be used for controlling or actuating machines serving for direct or telegraphic typographie composition.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A machine for producing perforated strips for composing and like machines comprising a keyboard for actuating electrically the various corresponding parts of the perforating-machine, a wheel having a printing and a matrix surface, a series of punches and dies and a presser all adapted to coperate to produce a strip having, besides the ordinary perforations in determined combinations, the impressions of the letter or character corresponding to each group of perforations, for the purpose of facilitating the verification and the correction of the strip by means of these marks or signs during the composing operation, the perforations and the production of the impressions being effected simultaneously substantially as described.

2.
