To Z5 whom it may concern..-

Be it known that I, OTTMAR Mimonnrna Lnu, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Machines for Producing lypc-l\Iatrices,Printing, &c., of whiehthe following is aspecification.

My invention relates to a machine for pro IO ducing impressions from type upon paper or other pliable or plastic surfaces, whereby a stereotype mold may be obtained direct; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out and indicated in the claims.

The object in general of the invention is to avoid the work ofthe compositor, and theheavy expense in type by means ofa mechanical mazo chine, through the employment of which the molds or matrices are produced direct in the machine without the aid of con'ipositors, and without any further stock of type than those contained in the machine.

2 The specific objects of the invention,among others, may be briefly said to be to produce a machine which shall be capable of having a series of disk type-wheelsarranged in such relation to each other as to present any given type in each disk at a pointwherc theimpression is to be taken, the particular type in each case being determined by a series of keys, each bearing a design corresponding to one of the types on each of the keys; to provide means 5 for automatically shifting the designating levers from one disk where the proper letter or figure has been designated to the next disk in the series; to provide means for automatically pressing the designated types together,

and locking them until the impression has been automatically taken, and then releasing them for a subsequent operation; to produce means for automatically causing the return of the designating apparatus after the impres sion of certain types has been taken, in order that other types may be designated and arranged at the point where the impression is taken for a subsequent operation; to provide means for automatically bringing the several types designated on the several disks into a line, and locking them until an automaticallyoperating platen shall have pressed the paper or other surface to the face of the designated types, and then automatically releasing t'he entire series.

To these ends the invention consists, essen tially, in the mechanisms and combinations of mechanisms fully illustrated in the accompanying drawings, which form a part of this specification, and in which Figuresl and l on Sheets 1 and 2 represent a top plan view of the device necessarily broken in each sheet. Figs. 2 and 2 are longitudinal sections taken on the line as w of Figs. 1 and 1. Fig. 3 is a transverse section taken on the line 1 1 of Fig. 2. Fig. 4 is a detail section showing the type disks,the shaft upon which they are loosely hung, and the intervening spring-friction spiders. Fig. 5 is a detail view ofone ofthe type-disks showing the radial recesses therein which receive the type. Fig. 6 is a detail showing the spring-friction spider having the spring arms projecting alternately and the key-projections for looking it to the shaft. Fig. 7 is a detail perspective of one of the type-arms. Fig, 8 is adetail of the segmentand rack-bar and some of their connections. Fig. 9 is a detail perspective of the oscillating pawl. Fig. 10 is a detail of the connectinggear on the main shaft and its 8c friction connection therewith. Fig. 11 is a detail perspective of the means for compacting and locking the designated types. Figs.

12 and 13 are detail sections of the type-pins, their concentric bearings, and the elastic band which exerts a constant force to hold the pins out of operation, one of the pins being shown as locked in position and in the act of designating one of the types.

Referring to the drawings, in which similar 0 letters of reference indicate like parts in all the figures, A designates the drive-wheel, hung rigidly upon a sleeve, 1, which in turn is loosely hung upon a shaft, 13, journaled in proper standards, as shown. The wheel A 5 and its sleeve have belt or other connection with a suitable motor, and revolve constantly when the device is in operation. The sleeve transmit motion to the'main shaft D,journaled longitudinally in the frame X by means of a concmo-convcx friction-disk, 9, located between the body of the pinion 9 and the end of the main shaft D. On the opposite end of the shaft D is an arm, 10, and pivoted in thcmain frame X, just back of the key-board, is a bellcrank, 11, operated by a key, 12. A keyspring, 13, serves withaconstantforce to hold the inner arm of the bellcrank lever 11 against the arm of the main shaft,and thus lock said main shaft against rotation, the friction-disk 9'riding idly on its bearings; but when the spring-force of 13 is overcome by the operator depressing thekey 12, the said arm of the lever 11 liberates the arm 10, and the friction-disk 9 operates to revolve the main shaft D one full revolution, or until the said 'arms again abut to lock the shaft D against further movement.

E designates a stationary drum furnishing pivotal bearings at 14 for a series of helleranklcvers, 15,in number corresponding to different symbols upon a series of type disks, which will presently be described, and with the keys upon the key-board. The keys 16 are provided with symbols correspondin; to the symbols upon the type disks, and said keys may be arranged in any convenient and approved manner, each key connecting with its appropriate bell-crank lever,17,'a'nd each lever 17 connecting with its appropriate lever 15, and a spring, 18, serving with a constant force to hold its appropriatelever, 15, at a position of rest until its force is overcome by the dcpression of the correspondingkey. For coir vcnience hereinafterthe levers 17 willbe designated as key-levers, and the levers as pinlevers.

F designates a stationary circular frame, to which is secured a cylindrical frame composed of an outer cylinder, 19, and an inner cylin der, 20," the two being arranged at a distance apart and concentric to each other. This frame is not an absolute cylinder, as at its lowest point it is reversed to form a recess, 21, in which is located a platen-guide, 22, which will be described.

I provide a series of type-disks, G, which are loosely hung on the shaft D. Each type;

adapted to be received in its appropriate recess 24. Thus arranged, the type will have lateral play due to the flexibility of the arms 25, but will each be held securely in its relative position by the arms of the disks 23, which arms form the recesses. The type-disks thus formed are hung loosely upon the shaft D, within the frame F, and between each adjacent pair of disks I locate springfriction spiders 27, having radial spring-arms 28 and inwardly-projecting ribs 29, which engage in longitudinal grooves 30, formed in the main shaft D. These spiders are hung upon the shaft D alternately with the typedisks, the arms 28 being bent in alternately-opposite directions when thus arranged, the projections 29 having formed engagements in the grooves 30, the spiders are forced to revolve with the shaft D, and the spring-arms 28-say six in number-- bear three at equidistant points upon one type-disk, while the remaining three bear similarly upon the type-disk on the opposite side.

The cylinder 19 is provided upon its outer surface with longitudinal ridges 3t, and between the ridges 31 the said cylinder is perforated at 32 to correspond radially with perfo rations made in the inner cylinder, 20. A band, 33. of rubber or other elastic material, is stretched across the ridges and arranged at one side of each circu m ferential row of holes. Pins 34,whiclr-l will designateas stop-pins, operate through the cylinders 19 and 20, and each pin is provided with an arm, 35, which arm is adapted to rest upon the outer surface of the band about midway between the adjacent ridges 31. The perforations in the inner cylinder, 20, are slightly larger than the pins,aud each pin 31 is provided with a recess, 36.- As the pin 34 isforced toward the center ofthe shaft D in a radial line the arm 35 bears upon the rubber band 33, and as this band is stretched between two of the ridgesthe tendency is to tilt the pins 34, so that their recesses 36 will receive the edges of the perforations in the inner cylinder, 20, and lock the pins in that position. The pins 34 also pass loosely through a trip-cylinder, H, and as this cylinder is forced in one direction by means yet to be described, all the pins which have locked in (see Figs. 3, 12, and 13) will be released, when the action of the several bands 33 will promptly carry them back to their normal position.

I designates a movable ring, hung on rods 37, which slide in proper guides in a direction parallel with the main shaft D, springs 38 serving to hold them with a constant force in the direction of the key-board, or toward the front of the machine. Each of these rods 37 is provided, near its end upon its lower surface, with arack, 39, which is engaged by a segmental gear, 7, one of which carries the disk 6, which is rigid with the shaft 4, and one of them,in addition to the rack 39,has a rack, 40, provided on either edge, arranged so that a tooth upon either rack 40 will be opposite the center of the space between two teeth of the rack upon the opposite side, and constructed so that the space between two adjacent teeth on either rack 40 will be equal to the space between the center of one pin 34 and the center of the next adjacent pin.

A movable ring, 41, is arranged concentric to the shaft 1), and located so that the depression of any of the keys will bring the inner arm of either of the pin-levers, 15, against its inner surface and force it toward the keyboard. This action will tilt a crank-lever, 42, upon its pivot 43, and by reason of its free end having a jaw, 44, which receives a pin, 45, upon a double pawl, 46, the said pawl is dis engaged from the inner rack 40.

It will be understood thatthe constant lendency of the movable ring I, by reason of the springs 38, is toward the key-board, and that the action of the frictional connection between the disks 5 and 6 is to overcome these springs and force the rings in the opposite direction, as would be the case but for the action of the double pawl and its connections, as described. The spring 47 serves to hold the pawl 46 engaged with the inner rack-bar40,and the ringI is locked. As soon as a key 16 is depressed, one of the levers 15 forces the ring 41 in a direction to tilt the lever 42, and said lever, acting on the double pawl, disengages it from the inner rack 40, and the friction connection 5 and 6 forces the ring I against the action of the springs 38 until the other jaw of the pawl engages the outer rack, when the ring I is again stopped. As soon as the pressure of the key is released, the spring 18 forces the lever 15 out of contact with the ring 41, and the spring 47 tilts the lever 43 back untilthe pawl 46 again engages the inner rack 40. This ring I at each of its complete strokes, as just described, passes the distance between one of the stop-pins 34 and the next adjacent stop-pin, and the said ring is provided with perforations and pins 48 to correspond with the number of pins 34, and the operation of this part of the machine will be briefly described as follows, referring to Figs. 2, 1, and 3: The operator, let it be supposed, wishes to arrange the types for a sentence commencing with K. He first depresses the key 16,

havingasymbol corresponding to K, which action tilts the corresponding key-lever, 17, through which the corresponding pin-lever, 15, is tilted until the horizontal arm thereof has forced the corresponding pin, 48, against the K stop-pin 34. This latter pin is forced inward against the influence of the band 33, (see Fig. 12,) and by the action of said band is tilted until itislocked. (See Fig. 13.) Each type-disk is provided with a stop, 49,,(sec Fig. 3,) and as soon as that stop 49 strikes against the K pin 34, thcletter K is in its position at the mouth of the platen-box 22, as will be seen by running the alphabet back from the stop 49 in Fig. 3. The action of bringing that disk in the position shown in Fig. 3, however, is not performed at this stage,

and I will continue the description with the K stop-pin locked. The action of the lever 15 has, through the lever 42 and pawl 46, released the rod 37, and as soon as the stop-pin has been locked and the key has returned to its position, the lever-pin 48 has been forced quickly back to its normal position by the action of its spring 50; the friction between the disks 5 and 6 has operated to force the ring I to the next adjacent type disk, where it is locked by the pawl 46, as influenced by the spring 47. The letter K now having been designated, and the parts all having returned to their normal positions, except that the ring I is adjusted over the succeeding annular row of stop-pins, the machine is ready for as many similar subsequent operations as there are type-disks, or until as many stop-pins are locked inward, and as many letters designated as are needed. It now being desirable to locate the several designated letters in aline opposite the mouth of the platen-box 22, the key 12 is depressed. This action, through the lever 11, releases the arm 10 of the main shaft D, the friction-disk 9 operates to revolve the shaft D, and all the type-disks turn with said shaft until one after another the stops 49 on the several disks abut against the stop-pins, as seen in Fig. 3, and the several letters desig nated by such pins are brought to one point, the frictionconnections 27 28 compelling all the disks to turn with the shaft D until each is stopped by its abutting against a stop-pin. As soon as the shaft D has made one full revolution, which is all that is required to bring all the disks into contact with the stop-pins, the arm 10 again strikes the stop-lever l1, and the friction-disk 9" acts idly on the shaft D, which again assumes a position of rest. The friction-contact between the disks 5 and 6, as has been stated, is sufficient to overcome the force of the springs 38, and as the ring I and its connections have made their complete, stroke I provide means for allowing said springs 38 to relieve the ring I inordcr that it may operate similarly in relation to the stop-pins and type-disks to designate other letters and combinations of letters. To this end, K designates a bellcrank lever pivoted to the side of the frame X at 51, and carrying upon its free end a grapple or fork, 52, which operates behind a collar, 53, to force the friction-disk5 out of contact with the disk 6. Upon the other end is formed an incline, 54, against which the arm 10 ot' the shaft D strikes when the shaft D is near the end of its revolution. As this arm 10 rides up this incline 54, the lever K tilts or rocks on its pivot 51, and disengages the friction-disk 5 from its bearing on the friction-wheel 6. To provide that no considerable friction shall retard the action of the springs 38, a trip-lever, 55, rests under a pin, 56, on the lever K until said lever is struck by a pin, 57, onthe rod 37 as the ring I passes backto its normal position, a spring, 58, forcing the lever .55 back for subsequent similar operation. As soon as the ringI and rods 87 are thus liberated from the action of the friction-disks 5 and 6, the springs 38 reassert themselves and throw said ring and its connections back to the position shown in Fig. 2, at which point the said ring strikes the trip-cylinder H, and ashort stroke of said cylinder disengages each of the designating stop-pins 34 from its locked position, and the rubber bands force them back into their normal position. Before the impression is taken it is necessary that the types should be pressed close together compactly in line and held firmlyin such position.- To this end I employ a circular reciprocating head, L, to

which are connected twolongitudiual bars, 59,

the rear ends of which act against springs 60, located in sockets 6L in clamps 62, which embrace cams 63 upon the shaft B. Rigid with the shaft B is an arm, 61, which at one point of its revolution abuts squarely against a pawl, 65, which is loosely hung on a rockshaft, M, journaled in standards 66, and carries an arm, 67. An arm, 68, upon the rear end of the main shaft D is arranged to strike this arm 67 just before it finishes its revolutionthat is to say, after said shaft D has arranged all the designated types in line-.and

. this action of the arm 68 releases the pawl from the arm 64, thus releasing the shaft B. Between a collar, 69, on the shaft B and the end of the sleeve 1, on which the drive-pulley A is hung, is located aspring friction-disk, 70, and this disk operates idly upon the collar 69 of the shaft B until the arm 64 has been liberated by the pawl 65, when, by reason of the friction, the shaft B revolves. As this revolution of the shaft B is being made, the cam action forces the rods 59 and head L against the type-disks to bring them close together, and at the same time a lever, 71, having a slot, 72, in which operates a pin, 73, of a socket, 74, forces a longitudinal bar, 75, the rear end of which operates against a spring, 76, so that its forward end, 77,will strike the line of designated types, now located at the mouth of the platen-box 22, and force them compactly together. It is also necessary that the designated types should now be held against lateral displacement, and to this end each type is providcd' upon opposite sides with recesses 78. Secured at 79 to the socket 74 is a rod, 80, which passes approximately parallel with the bar 75, and is provided at its forward end with a frame, 81, having flanges 82, which slide in guides 83, formed in the platen box near its mouth, and having also flanges 84, which slide in the type-recesses 78. It will thus be observed that at the same time the head L is forcing the type'disks together as a body the bar 75 is further forcing the particular types, which have been designated, together, and that the frame 81 has been simultaneously operated to hold the designated types in alocked position. (See Fig. 11.) As thus conditioned the machineis ready for taking the impression. For convenience, I describe the impressionreceiving surface as of paper; but it is apparcut that the kind of material is not important to the invention.

N designates a reel or roller carrying a tape, 85, which is adapted to be fed through the machine beneath the type at the mouth of the platen-box, and resting upon a platen, O,which operates loosely in the box or well 22. Under a pin, 86, on the platen O, rests the end of a power-lever, 87, pivoted at 88 to the frame X, its free end passing rearward and resting in the line or track of the arm 64. In the revolution of this arm 61 it acts upon the lever 87, the pivot 88 of which is arranged so as to multiply the power greatly to elevate the platen O, which movement carries the paper-tape 85 up against the line of designated types, now pressed and locked into a compact body, and takes the impression. As soon as this is done, the arm 64 has passed from the lever 87, the cam 88 has changed position, the spring 89 retracts the rod 75 77 and holding frame 81, and the platen 0 falls by gravity to its normal position by reason of the spring 100 acting to throw upward the free end of lever 87, which correspondingly lowers the other end of the said lever where it engages the pin 86 of the platen. The tape 85 passes between feedrollers 90, one of which is provided with a ratchet, 91. with which engages a pawl, 92, pivoted at 93 to the frame, and held forward by a spring, 9L To the free end of the pawlarm is secured a cord, 95, which, passing rearward under a pulley, 96, and upward over a pulley, 97, is secured to the socket 74. As this socket 74 is forced forward, as just described, to compress the types, the rope or cord 95 is slackened and the spring forces the pawl 92 idly over the ratchet to take up said slack; but as soon as the impression has been taken and the socket 74 is passing rearward, the cord forces the pawl 92into engagement with the ratchet, and the paper is fed forward a distance just equal to the space occupied by the compressed type, the parts being properly proportioned to that end.

It will be observed that the several movements described are automatic, and it must be understood that the several parts are propor tioned and timed to effect the operations men tioned.

The voluntary acts of the operator may properly be said to consist of the manipulation of the keys to designate the types, and, sec ond, the depression of the key 12 to set the machine in motion. The stop-pins lock and unlock automatically. The designated types are brought to a common point automatically. The types are compressed and locked auto matically. The platen is operated automatic ally. The receiving-surface is fed to the type automatically, and the several parts return to their normal positions for similar subsequent operations automatically. These movements are timed so that the first action of the machine is to designate the types, the next to bring the designated types to the platen-box in a line, and at the same time, or as soon as they are in line,'to compress them compactly and lock them, then to retract the ring I and release the stop-pins, then to take the impression, then to feed for the next impression.

Modifications in details of construction may be made without departing from the principle or sacrificing the advantages of my invention, the essential features of which will be readily understood from the foregoing description, taken in connection with the drawingsas, for instance, a positive gear or clutch may be employed instead of the friction-disks 9 and 70, and weights may be used in several connections instead of springs.

Having thus described my invention what I claim is 1. In a machine for producing impressions from type, the combination of a series of typedisks capable of rotation on an axis, with a series of keys corresponding to the type-symbols on the disks, and intermediate connecting mechanism, such substantially as de scribed, whereby the disks are rotated to bring the designated type in line at a given point.
