MATRIX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 479,7 72, dated July 26, 1892.

Application filed May 31, 1887. Serial No. 239,735. (No model.)

To aZZ whom it may concern.-

Be it known that we, GEORGE A. GooDsoN, acitizen of Canada, and ALEXANDER S. CAPE- HART, a citizen of the United States, residents of the city of Minneapolis,in the county of Hennepin, State of Minnesota, have invented a new and useful Matrix-Making Machine, of which the following is a specification, reference being had to the accompanying drawings.

In the art of printing as now generally practiced newspapers and similar work requiring many duplicates are printed from stereotype-plates, which are cast from a matrix obtained from a form of hand-set movable type.

The object of our invention is to provide an improved mechanism by means of which the matrix may be made from the copy by the successive impression in the matrix material of dies corresponding to the required characters, instead of setting up type and then forming the matrix from the bed or forms of type.

The mechanism which constitutes our invention comprises among its more noticeable features the following: first, character-selecting devices for bringing any one of a large series of characterdies to a common center, classified into groups according to the space required by each; second, a suitable movable bed or carriage for the matrix material for supporting the same under the common center; third, independent feeding devices for feeding the matrix material, bed, or carriage the unit or the number of units of space required by the different characters; fourth, connections between each group of character-selecting devices and the proper feeding devices for that group, so that the act of selecting a given character will bringinto action the necessary devices to effect the due feed of the matrix material for that character; fifth, mechanism forinstantaneonslydepressing the die at the common center; and, sixth, construe tions, whereby the feeding devices and the die-depressing device are controlled by electricity.

In the drawings, Figure I is a plan view of our entire machine with the hammer and its actuating-magnet removed. Fig. II is a longitudinal vertical section on the line XXX X of Fig. I. Fig. III is a plan view of the bed-plate except a part of the front portion of the same and the feeding mechanism. Fig. IV is an enlarged viewof the central part of the machine on the same line as Fig. II. Fig. V is a detail showing the type-carrying rods. Fig. VI is avertioal longitudinal section of a part of theindex-plate or keyboard, and Fig. VII is a modification of the same. Fig. VIII is a vertical cross-section through the center of the machine at right angles to Fig. IV. Fig. IX is a vertical cross-section on the line. Y Y of Fig.I Fig. Xis a detailof the same in vertical section on'an enlarged scale. Fig. XI is a longitudinal vertical section of the hammer-circuit-closing magnetand its springarmaturein position on the bed-plate. Figs. XII and XIII are vertical central sections of a part of the mechanism for feeding the matrix lengthwiseof the machine. Fig.-XIVisa horizontal section of Fig. XII'or XIII or plan view of the spring-case with the cap-plate removed. Fig. XV is a plan view of the rollers,detached, for feeding the matrix crosswise of the machine; and Fig. XVI is a side elevation of the forward end of the same in position on the matrix-carriage. Fig. XVII is a view showing. the mechanism for feeding the matriX material to form new lines in front elevation.

The main frame is composed of a metallic bed-plate 1, suitably shaped to support the working mechanism. All the parts of this bed-plate are cast in one piece; but the forward part A is in a different and higher plane than the central and rearportions A and A, the two horizontal parts of the plate being connected by the vertical plate or offset a, which projects slightly above the level of the front plate A. The central and rear portions A and A are separated by the verticalcross plate or rib a, which projects above the bed-plate to the level of the plate a. This cross-rib a is cut away at its central part. as shown in Fig. III, for a purpose hereinafter named. The bed-plate is provided with suitable feet or supports, which in the drawings are shown as formed by projecting downward or the typerod held therein must come to the the end and side plates and one or more solid cross-ribs. Directly under the center of the part A is cast integral with the bed-plate the heavy longitudinalrib or base-block a. Bigidly secured to the vertical parts a and a is a hardened and smoothly-ground bearingplate'2, provided with a countersunk or tapering hole B exactly in its center,which point may be called the common center or printingpoint. This hole tapers from above downward, and is of a size on the under side of the bearing-plate corresponding exactly to the size of a die, and serves as a guide for the same. On this bearing-plate 2 rests an inverted-box-shaped capplate 3, having the central parts of all its four sides cut away. The

plates

2 and 3 and the bed-plate 1 are tightly bolted together, forming between them the

free spaces

4 and 5.

To the front part A of the bed-plate 1 is rigidly attached an index-plate or keyboardfi, which for purposes of insulation is made of vulcanized rubber. In this index-plate are apertures or holes Z7, each of the characters which it is desired to use being represented on the index-plate by an aperture or hole, and each aperture may be designated by having the character represented thereby marked on the plate near it; but whether this is done or not the plate may for convenience in the description and claims be denominated a character-board. The apertures in the indexplate are preferably arranged in a series of concentric hexagons. These apertures are adapted to receive the key or point of the lever '7, and may be termed key-seats.

7 is a combined key-leverand type-aligning plate. Its front or lever end 0 is provided with a key S, for fitting into the perforations of the index-plate, and its other extremity is enlarged into a disk D, and is provided with a series of type-rod seats or square holes 9, which correspond in number and inversely in location with the apertures or key-seats in the index-plate. -About midway of its length this aligning-plate is pivotally secured by a pivotpin and nut 10 to a small cross-head E, which is held in a longitudinal slotcin the forward part of the bed-plate by suitable guides F.

The type-rod seats or holes 9 correspond inversely in location to the apertures or keyseats in the index-plate, and they are made necessarily to do so by making the latter the gage for cutting the former-that is to say, let the punch or drill be at a fixed point a definite distance from the center of the indexplate, and let the plate 7 be pivoted in a slot in the press-plate. Then insert the key 8 successively in the apertures or key-seats of the index-plate and punch out the corresponding type-seats. Thereafter any given type-seat common center when the key 8 is in the corresponding perforation of the index-plate The type-seat disk D is provided with pen dentstuds or feet 11, which rest upon and traverse the bearing-plate 2. If so desired, these I feet may be provided with swiveled casters or ball-rollers (not shown) to minimize friction.

12 is a top type-seat plate, which is an exact duplicate of the disk D, with coincident type-rod holes, and the two plates are held to gether at a fixed distance apart by the shouldered studs or bolts 13, to the opposite ends of which the plates are riveted.

14 are short type-carrying rods, each of which has a type on its lower end and is provided with a hardened head at its other extremity. Each type-rod is also provided with an annular flange or shoulder (Z. These typerods are placed in position, each in its respective type-seat, with their type ends protruding below the disk D and their square or top ends projecting above the plate 12, and are sustained in that position by the coiled springs 15, encircling the rods and pressing against the disk D and the annular flanges d. These two plates, with their type-rods, make up what we call the type-carriage. In virtue of its pivotal connection to the cross-head in the slot of the bed-plate the aligning-plate 7 has a movement laterally and longitudinally in the horizontal plane, and its lever end 0 is a flat spring with sufiicient movement in the vertical plane to retract the key from the index-plate.

With the mechanism now described it is evident that any given type-rod may be brought to the common center. It is equally evident that if a stroke can be given to the type-rod while at the center an impression can be made on any suitable matrix material properly held on a resisting-bed. We do this by electromotive force and mechanism, as follows: The cap-plate 3 is provided with a central hole directly over the common center B. Into this fits a sleeve 16, which ismade of brass to prevent permanent magnetism. In the sleeve is a hardened metallic pin 17, which is sustained IOU in position with its head above the top of the sleeve by the spring 18. On the plate 3 we place a large helix electro-magnet 19, having the armature 20, which we make to serve as a hammer. The hammer is threaded on its upper extremity and provided with a handnut 21. A spring 22 encircles the hammer resting upon the top of the magnet and bearing against the under surface of the handnut and serves to retract the hammer after the stroke. In the hollow axis of the magnet, at the bottom of the same, is fixed a core 23 for the purpose of increasing the power and limiting the downward stroke of the hammer and the pin. This core is rigidly secured to the magnet bed-plate 3 and has its axis bored out to fit over the brass sleeve 16 and its inclosed pin 17. These parts fit snugly together. The hammeris provided with a downwardly-proj ectin g head 24, which just fits into the hollow axis of the core 23. mer nears the end of its stroke it moves Very rapidly. Sufficient outlet will not be afforded for the escape of all the air between the body of the hammer and the core 23, and an aircushion will thus be afforded, preventing jarring contact of the two surfaces. By mak; ing and breaking a circuit to this magnet 19 strokes may be made at will with the armature-hammers 20. That part of the bed-plate 1 lying directly under the index-plate O is provided with corresponding coincident holes e. In these holes are placed vulcanized rubber sleeves or bushings 25, and in the bushings are placed the short platinum-headed rods 26, which are held in position with their heads flush against the lower face of the index plate by the encircling springs 27. The lower ends of these rods are connected with branch wires 28, which form part of a circuit, as hereinafter described. In the space 4 directly under the bearing-plate 2 and resting on the bed-plate is placed a matrix carriage 29, consisting of front, rear, and side vertical plates f, the heavy central rib g, and top plate H, and the guides 71, attached to the front and rear plates and projecting above the level of the matrix bedplate or resistance-plate H. This matrix-carriage is of the same width as the bed-plate A and is held from lateral displacement by the vertical projecting flanges 30, which are rigidly attached to the bed-plate. The central rib g is solid and rests directly over the bedblock a". To the front plate of the carriage is rigidly secured the rack-bar 31, which is provided with the teeth 32 on its inner vertical face for engaging with a driving-pinion. This rack-bar is supported by the bed-plate and extends toward the rear of the same. At a suitable point in the bed-plate is fixed a vertical post 33, and on this post is placed a loose sleeve 34, provided with the pinion or gear-teeth on its periphery at 35. This pinion 35 engages with the rack 31. On the sleeve 34 is placed a cylinder-shaped springcase 36, which is provided with teeth, constituting a rack 37, on the upper two-thirds of its periphery. This spring-case is fastened to and turns with the sleeve 34, and may be adjusted vertically thereon for a limited distance. A pin 38 through the post 33 prevents any vertical movement of the sleeve and pinion and limits the vertical adjustment of the spring-case. Over the toppart of the post 33 fits a cap-sleeve 39, passing through a hole in the cap-plate of the spring-case. This capsleeve has a free vertical movement on the post, but is prevented from turning thereon by a vertical feather 40. This cap sleeve rests on the cap-plate of the spring-case by the annular flange 41, and is secured to the same in any suitable way, so that the capplate may be free to turn on the sleeve, but so that when the sleeve is raised or lowered the cap-plate and entire spring-case will be raised or lowered with it. As shown, itis held by the spring in the case.

In the case 36 is a coiled flat spring42, which at one end 43 is attached to the vertical wall of the case and at the other end 44 is attached to the sleeve 39. It is evident that this spring will be wound up by turning the case from left to right and that the spring will turn the case and pinion in the opposite direction when set free.

On the rear part of the bed-plate, in convenient suitable positions with respect to the spring case and rack, we place a series of magnets h M and M and to a series of vertical posts K, K, and I we pivot a corresponding series of armatures N, N and N the free ends of which are supported in their proper horizontal plane by a series of brackets L L L', suitably supported on the bed-plate. To the outer end of the armatures are pivotally attached a series of spring-pawls P P P held in proper position for engaging with the ratchet on the spring-case 37 by the small fiat springs ppp. After the circuit has been opened the armatures are retracted by springs Z Z 1", attached to studs 45 on the bed-plate. These magnets M, M and M have armatures which move through different distances which are multiples of a common unit of space and move the pawls through corresponding distances. For example, M moves the pawl P three times as far as M moves pawl P. As many of these magnets are used as may be required to correspond to the spaceclasses into which the type characters may be grouped. A lever 46 is fulcrumed to a post 47, fixed on the outer left-hand corner of the hammer bed-plate 3. One end of this lever is provided with a hook 48, which engages a loop or link 49 in the end of the cap-sleeve 39, and the other end is provided with a finger disk or handle 50. By pressing down on the disk 50 the spring-case may be raised from the position shown in Fig. XII to that shown in Fig. XIII and the ratchet on the periphery of the case will be thrown out of gear with the pawls and the case and pinion will be rapidly turned in the opposite direction by the spring 42. During this movement of unwinding or retraction of the carriage the pawls rest against the smooth part of the periphery of the spring-case. The smooth part is of a larger diameter and connects with the ratchet part by an inclined or cam surface, thus preventing the pawls from catching under the ends of the teeth when the case is lowered.

On the front part A of the bed-plate 1, intermediate the hammer-magnet and the index-plate, we place a circuit-closing magnet 51 and a spring-armature 52, which isbolted to the bed-plate by the bolts 53 and insulated from the same by rubber bushing 54. The free end of this armature extends beyond the magnet 51 in the direction of the hammer- -magnet and is adjustable on a post 55, made of hard rubber or other insulating material and provided with a screw-threaded top and a thumb -nut R for varying the distance through which the armature may be made to move. A- wire S connects the insulated core 59 of this magnet 51 with the hammer-magnet 19. To the under side of the bed-plate is attached by the bolts 53 a flat metal spring 56, having metallic contact through the bolts 53 with the armature 52 and extending; at right angles to the armature to the left side of the bed-plate. At this point it comes in contact when closed with the metallic sleeve 57, which is inclosed within rubber bushings 58 and extends up through the bed-plate and is connected to a wire S", leading to a source of electricity. A vulcanized-rubber key 60 rests loosely in the sleeve 57 and is provided with the hand-disk 61, within easy reach of the operators left hand. The wire S is connected at one end to the hammer-magnet 19 and at the other to a dynamo, (not shown,) and the circuit is completed through wire S, core 59, armature 52, metallic bolts 53, spring 56, sleeve 57, and return-wire S. By pressing the key 60 this hammer-circuit may be broken at will.

As hereinbefore stated, the type characters or type-rods'are classifiedinto groups according to the amount of space required by each, measured by a common unit, as the one, two, and three unit classes, &c., and from their respective corresponding metallic rods 26 branch wires 28 connect to the corresponding main Wire for any given class. The wire marked 63 is such a main wire for the class of characters requiring one unit of space, and may be called the one-unit wire. It leads from its respective branchlets 28 to and through the one-unit magnet M, and by its extension 63" connects with a source of electricity (not shown) 6 1 and 642, and 65" and 65 are the corresponding two and three unit wires,-runningfromtheirrespectivebranchlets through the magnetsM and M to the same source of electricity. From this common source of electricity, which may be either a dynamo or a battery, (not shown,) the common outleading wire 62 extends to and through the magnet 51 and is soldered to the bedplate A. From the bed-plate the current passes through the pivot-pin 10 to the keylever O and completes the circuit through the key S.

It will be noted that the feed-magnet circuits and the hammer-circuit are entirely independent and that the latter is closed by a magnet 51, placed on the former. For the hammer-magnet we use a quantity-current, employing a large wire to avoid any possible chance of shock to the operator, preferably employing a dynamo as the source. For the feed-magnets We use an intensity-current,

employing a small wire, and either a dynamoor a battery may be used as the source. By the proper independent connections the same dynamo may be made to supply the propercurrents to both circuits.

At all points where circuits are made and broken platinum surfaces are used. A pawl 76 is attached to a post 77, fixed to the bedplate A, and engages the teeth on the springcase 36 and is disengaged therefrom by the vertical movement; of the case, the same as the pawls P, P, and P'. This pawl serves to prevent any slipping backward of the case and to make the successive throws of any given pawl of exactly the same length.

The mechanism so far described will bring the type to the common center, feed the matrix material along the line, and make the stroke. The lateral movement to effect the spacing between the lines is secured by the mechanism shown in Figs. III, XV, and XVI. A pair of rollers 66 are supported on the left side of the matrix-carriage 29, one directly over the other, so that the top of the lower roller shall be on the same level as the matrix-bed plate H. The rear ends of these rollers are provided with inter-meshing gearwheels 67, and the upper roller is provided with a ratchet-wheel 68 on its forward end. A bracket 69 projects outward from the side plate of the matrix-carriage, and to the vertical arm of the same is pivoted a pawl-lever .70, which carries on its inner extremity a spring-pawl 71 for engagement with the ratchet-wheel 68. To the top of the pawl-lever is attached a finger disk or key 72 within easy reach of the operator. A resistancespring 73 is fastened to the horizontal arm of the bracket and presses up ward against the pawl-lever, serving to hold the pawl out of engagement with the ratchet-wheel. Under the free end of the pawl-lever is placed an adjustable stop, consisting of a vertical post 74, attached to the horizontal arm of the bracket, screw-threaded on its upper extremity and provided with the screw-threaded hand-nut 7 5. By adjusting this hand-nut the throw of the pawl may be made longer or shorter and the spacing between the lines be varied at will. To insure accuracy, a graduated scale may be attached or marked onthe post. As shown, these rollers are moved by hand.

In the modification shown in Fig. VII the rods 26 are dispensed with and the key 8 is itself made vertically movable Within a rubber bushing and is retracted by an encircling spring. The matrix material is shown and marked 7 S in Figs. II, IV, and VIII.

The operation of our machine is clear from the foregoing description. WVit-h the keyS the operator spells out the words on the index-plate. The resultant movement of the alignment plate brings the corresponding type-rods to the common center directly under the hammer and over the matrix material. The electrical connections through the key-point and feed-magnets move the matrix material the requisite units of space along the line. Simultaneously therewith the hammer-circuit is closed by the magnet 51, and an instant later (suflicient but almost inappreciable) the stroke is given by the hammer and the impression is made. In case increased space is wanted, as between words or at the end of the line or for paragraphs, or if for any reason it may be desirable to avoid the stroke of the hammer, the operator presses down on the disk 61 and opens the hammercircuit. In moving the matrix-carriage along the line the armatures have wound up the spring 42 within itscase about the non-revoluble sleeve 39. When the end of the line has been reached, the operator presses on the disk 50, disengaging the ratchet-teeth on the spring-case from the pawls, and the spring unwinds, retracting the carriage to its starting-point. Simultaneously therewith the operator presses on the disk 72, feeding the matrix material laterally the requisite space, and all is in readiness to start a new line. It will be noted that the stroke of the hammer is made to follow and not precede or coincide with any movement of the matrix material or the type-rod by making the armature of the hammer-closing circuit move through a larger space than the longest distance moved through by any feed-magnet armature, and the necessary proximate coincidence or simultaneity of movement is secured by closing the hammer-circuit through a magnet placed on the feed-circuit.

The common initiative, all the movements being started from the index-key, and the absolute precision with which all the parts are made, necessarily, to perform their respective functions at the right instant of time are very material features of our machine. There is no chance for the parts to fail in their functions through wear and tear and resultant lost motion.

For the matrix-body we use whatever material will best serve the. purpose. Card-board gives excellent results, and we have also found that good results can be obtained from thin sections of wood cut across the fiber or grain.

Justification is effected by the proper preparation of the copy. As hereinbefore stated, the type characters and the feed movement all correspond to certain multiples of a common space-unit. The copy is measured and prepared by the same scalethat is to say, a common space-unit is adopted for measuring the copy, the type-dies, the feed movements, and the printed line. Columns are adopted for the printed page, which are in width exact multiples of said space-unit. The unit is made sufficiently small to measure the smallest type character, and every other character used is a multiple of that. By the eye counting the characters and spaces between words or by proper machinery the copy is measured and the point which will bring the matter to the end of a line is noted thereon. If that point does not fall at the end of a syllable, the division-point is thrown back the necessary number of letters, and the corresponding necessary number of unit-spaces to be thrown in are noted above the word and may be distributed by the proper notation between the words along the line. In this way all the operator has to do is to glance at the last word of his line and he sees whether or not it will come out flush with the end of the line, and if not he throws in between the intervening words the requisite number of spaces. J ustification is thus absolutely assured. The copy can be prepared in this way with great rapidity by the eye alone.

It will be understood that modifications in the electric connections and the electric controlling devices for said electric connections, as Well as in many of the minor features of our mechanism, may be made without departing from the spirit of our invention.
