To all 1071/0711, it 'muy (fu/merit.'

Be it known that I, O'r'I'xIAR NERGEN- 'IHALER, of Baltimore, in the State of Maryland, have invented a new and useful Improvement in Linotype-lilachines', of which the following is a specification.

This invention relates to that class of machines which, being actuated by finger-keys representing 'clnujactcrs and spaces, produce andassemblc ready for nselinotypes or typebars, each having the type characters to print ancntirc line. 'lbe type surfaces or forms thus created as demanded areused in the same. manner as forms composed of .the usual single-letter type, and being once used are returned tothe melting-pot.

Likelthose represented in the various pai-- cuts heretofore granted to me the present machine consists, essentially, of a series of mat-- ricos and spaces, mechanisms by which they are selectedA and assembled in line, the line presented against the open side of a mold to close the same, thc mold supplied with molten metal to form the linotype bearing the characters ofthe opposing matrices, and, lina'lly,

the linotype delivered and the matrices and.v

of its characters maybe brought into operai'L tive position in the same general manner as iu my application, Serial No. 375,632,filed1)e" cember :223, 1890.

The present. machine is distinguishable from thbse ofzmy earlier patents in that. the

matrices have a twofold 1nove1nent-tirst,tl1at of traveling or being transported successively from Ithe magazine. or place of storage bodily to' a common assembling or composing point, where they are assembled side by side in line,v

and, second, that of lngitudinal adjustment in relation to cach other in the composed line.

The first action brings together in line matricos which contain the requiredcharacters, while ihesccond brings the special characters demandcd,o11c on cach matrix, into a common liuc for presentation to tbc mold.

Fig. is a perspective view of one of the matrices. Fig. 21 is a perspective viewof one of thelinotypes the product of thel machine.

As the basis of my machine I provide a series of matrices A, such as shown in Fig. 20, each consisting of a plate of brass or like material bearin g in one edge a number of letters or characters a., and having in the opposite edge a corresponding number of aligning- `notches a', and in one end a notch with distributing-teeth az in its edges. Each matrix is made of a thickness corresponding with thel width of the characters borne in its edge, characters of the same or practically the same width being grouped on the. same matrix. There will be a sucient number and variety of matrices to carry all the characters to be printed,and of each matrix there will be a number of duplicates. A matrix bearing any given group of` characters differs as to the number or relation of its teeth a from a matriX bearing any other group, so that the teeth may coperate with a distributor-rail, 'and thus direct the matrices to their appropriate magazine-channels after the manner fully set forth in Letters Patent of the United States rgranted to meon' the 16th day of August,

1886, No. 347,629. I also provide for use in connection with the matrices a series of spacing-.wedges B, such as shown in Fig. 17, each consisting of a thin tapered bar of steel having a notch b in one end. These wedges are to be thrust into the assembled lines of matrices at suitable points for the purposes of producing spaces between the words, expanding or justifying the line to the predetermined length, and aidingthe matrices to close the mold, so as to confine the molten metal during the casting operation.

The first part of the .machine proper is the composing mechanism, designed to select in proper order the matrices bearing the designated characters and spaces and assemble them in line side by side, at the same time adjusting the matrices endwise in relation to each other, so that the designated characters, one on each matrix, will stand ina common line.

Thesecond part of the machine comprises mechanism for transferring the assembled lin'e of matrices and spaces to the front of the mold, that it may be closed thereby, and advancing the spaces to justify the line.

The third part comprises the 'mold and means for supplyingthe molten metal thereto and fordelivering the linotypes.'

The fourth part' is the distributing mechanism intended to return the assembled matrices andspaces to their magazines or storageplaces after each linotyp'e is cast.

Passing now to the details of the machine, attention isdirected mainly to Figs. 1, 2, 3, and 4, in which C represents a rigid main frame to be made of any form adapted to sustain theoperative parts.. In the present instance the frame consists of parallel plates spaced apart by connecting posts or pillars, as shown in Figs. 1, 2, and 3, but omitted to some extent in the other figures in order to expose more clearly the operative parts.

D, Fig. 2, is a stationary inclined magazine havinga series of channels to contain theassorted matrices. 'lhese channels converge toward their lower ends and deliver through a common mouth or channel, so that as the matrices bearing the designated characters are released they descend one after another to the same point to be added to the end of the line in course of composition. Each channel isprovided, as vshown in Fig. 4, with an escapement, which may be of any suitable Y form, but which, as shown, consists of a lever d, pivted at d', and carrying two pins d2, which, as the lever is rocked, alternately enter the -top of the channel, so that one matrix at a time is released and permitted to descend to the place of composition. Each escapement-lever is connected by a wire d, lever d4, and wire d5 with a bar da, Fig; 2, arranged to slide upward and downward in the frame.

Through each of the sliding bars d0 there is extended loosely a series of finger-keys E, Sheet 4 and Fig. 9, arranged in a vertical row and equal in number to the characters on one matrix. These keys are pivoted at their rear ends on horizontal rods EX, mounted loosely. in the main frame, as shown in Figs. 4 and 12. Each key represents one of the characters, and on operating either one of the keys in the same vertical row one and the same matrix'will be discharged from the magazine. The several keys are used to release the same matrix in order that they may respectively, through devices presently to be described, act to stop the descending matrix at different points, so as to bring one or another of its IOC characters as demanded in operative position 'dividnal matrices. A

The mechanism for arresting the ldescending matrices in dierent positions is shown iii-Figs. 2, 3, 5, 6, 7, S, and 9, in which F F', &c., arehorizontal slides mounted in the frame, so that they may be advanced one at a time into the path of 'the matrix, as in Figs.- 7 and 9, to sto'p it in one position or another, according to the character to be used. Each slide is connected to an arm f' on a rockshaft f2, carrying 'a second arm f3, which engagesaplate f4, arranged to slide beneath all the keys in a horizontal row and provided with an inclined notch f5 under each key, so that when a key is depressed to discharge a matrix it will at the same time move the bar f4 endwise, and thereby project the appropriate stop-slide F to check the matrix, with the character represented by the key, at the desired point. All the keys in each horizon- IXO ltal row aetuate the same stop-slide, so that ment, so that the machine is enabled to produce a large number of charactersvby the use of a small number of matrices and channels,

The matrix-arresting slides or'stops F F', dac., are preferably constructed, as shown in Figs. 5 and 9, with lips F5 to 'override the lower ends of the matrices as the latter are' arrested in theii` movement, and each slide is subjected to the act-ion of a spiral depressingspring F6, as shown in Fig. 5. These springs actto urge the slides down. with moderate frictional eilect on the inatrixasdt rides un- -der the lip of the slide, the etect being to vcheck the momentum of the matrix with an easy action and to'prevent it from rebounding. As the matrices are arrested one after another the resulting line is sustained upon the bed-plate c, forming part of the main frame, which bed-plate is provided with :trib

1 c', Figflti, which enters one of the notches in the lower edge of each of -the matrices and holds it from shifting endwise in relation to the others, aithough it permits the line to advance horizontally to the left as it len gthens.

As each matrix is stopped in its 'descent it is carried laterally against and added to the rear end of the line and the line'moved bodily forward to make room for the next matrix by means 'of the reciprocating pusher y, Figs. 9 and 12, which may be actuated by .lever G and magnet g' or in any other suitable manner. As the line, increasing in length,.ad vanees on the hed its advance is resisted and the line heldin close order, as shown in Figs. 3, 12, and-l2, by a plate 1I,"carried by arms h, attached to arms hon rock-shaft h2, having a Weighted arm 7L. 'lhe'magnct g will be mounted in a circuit `closed bythe action of cach finger-key, so that the action oli a kcyto bring amatrix to the line is followed bythe advance of k,the entire line by the pusher, as already explained. Fig. i? illustrates a simple method of thus closingthe cireuitby the finger-keys, the barsqd, which are actuated. by the' keys, being arranged to press conducting-fingers in len e side of the circuit into conl tacting with the bar forming a partof the other .side of the circuit.

It is to be understood, however, that the pusher may be constructed and operated in any other manner whieliwill give itessentially the same mode 0f action.

" Tf. is necessary in the course of composition to introd nee the spacing-wed ges between cach word and the' next-tl1at is to say, betweenA the matrix bearing the last character of one word andthe matrix bearing the iii-st charac- -ter Aof the next word. To this end I arrange the wedges, as shown in Fig. 16, side by side vin 'two groups with theirthin ends projected toward each other. I sustain them at their outer ends on two stationary wires or b', passing through their notches, these Wires being supported rigidly, as shown-in Fig. ll,

by lips bl", extending inward from the frame and passing through .the open vends of the ,notches in4 the spacing `wedges. The Qtwo groups of wedges are assembled normally, as shown in Figs. 12 and 16, above the pointsat which the incoming matrices are added to the line, and the inner ends of the wedges rest upon and are sustained by shoulders on the main frame, with lips b2 at the front edge tov prevent them from sliding downward oil of the shoulder. Y

In order to introduce a wedge into the line, it is onlynecessary to lift the front wedge clear of the lip h2, Figs. 11, 12, and JU, so that it may pass thereover and dropat its thin end into position behind the composed line and in front of the next matrix to be introduced. In this manner the ends'of the wedges are introduced'into and made a part of the line, with which they are free to advance by sliding along the'guide-wiresb', as clearly shown invFig. 1G. The release of the wedges that they' may thus fall into the line one after another is effected, as shown in Fig.

13, by a rocking lever bhaving in opposite sides off its axis two pins 1)4, which act beneath the front wedges of therespectivc groups, so that as the lever is vibrat'ed a guides IOO wedge is delivered first from one group and then from the other into the line. -As the successive wedges thus introduced are tapered in opposite directions and as thctapcr.

is Vcry slight the matrices are not thrown out of their parallel positions to any appreciable extent. If preferred, however, Atwo wedges may bedropped into the line for each space. In such caso their outer orldistant surfaces will be parallelA andthe adjacent matrices will consequently remain parallel, se that there will be no deviation oi' their characters from vthe vertical. 4'lhc rocking lever for deliverinsert'edin the iirst instance with. their thin ends in the line, as shown in rFig. 1U, and thatthey thus relnain until the con'ipletion of the composition, after which they are advanced cndwise through the line l rom epposte directions to ellect the justification in a manner hereinafter explained.. The stationary Wires b bf', on -which the outer ends ofthe wedges are sustained, are continu ed,.as shown in Figs. 12, 12, and 16, to sustain the wedges as they advance with the line to the casting 'position and they are also turned upward at their Aright-hand ends and carried horiz ntally to the left at a' higher elevation, as shown at bx, and this in orderthat the wedges carried from the lower ends of the wire with the line may be reapplied to the wires at their upper ends, as hereinafter explained.

In Figs.2,3, 10,1l,12,1G, and 18, I representsA a rising and falling table sustained and guided by a tubular or. box-like shank t', sliding through and guided by the plates of the main frame. When in its lower and normal position, this table forms a continuation of the rested and supported. v The table is also proy vided at its opposite side with a verticallysliding jaw i?, Fig. 12, which rises behind the transferred line to confine the same upon the table and determine its length when the j listifcation occurs. The composed line is shifted frointhe bed c to the table I. The plate H, heretofore mentioned as a yielding resistantv to sustain the front of the line during composition, is lifted' by hand from the front and transferred to the rear of the line, so that it serves as a means of carrying the line forward. The plate H will be lifted from the front and transferred to the rear by hand; but it is obvious that suitable operating mechanism could be applied, if desired. It will benoticed that this plate serves, therefore, the double function of a resistant to keep the line in close order during the course of composition and thereafter of a transferring'device to move the completed line from the bed to the table. In order to hold the matrix-line in compact form while it is being transferred to the table and after the plateH has been transferred to the right end of the line, I provide a second resisting or sup porting plateII', (see Figs."3, 12, 12, 12", &;c.,)' carried on one-end of the sliding rod h5, acted upon by a spiral spring h, which tends constantly to urge the plate to the right. When, therefore, the plate H' takes its place at the left, it offers a moderate resistance to the line as the latter is shifted to the left. 'lheelevation of the jaw 113 behind the line on the table is'effected by means of thebefore-nientioned lever h3, Fig. 12. It will be remembered that this lever isconuedted through intermediate parts with the plate 1I, and as the plate completes its movement in shifting-the linethe lever h3 encounters the jaw 113 and carries it upward. It will be understood,

however, that any equivalent means may be employed for. raising and lowering the jaw, as these parts re not of the essence of the invention and affect the speed rather than the operativeness of the machine. y When elevated, the j awa may be sustained by leaving the plate -H inside of the jaw, so as to maintain the lever H3 in the elevated position, or if said plate is lifted clear of the line the jaw maybe sustained. by friction in its guides, which will be augmented for the time being by the pressure of the expanded matrixline'. As the composed line is moved upon .the table the contained -space-bars .slide, as shown in Fig. 16, from the ends of the guidewires b'onto horizontal ribs l, formed on the upper ends of arms L, the lower ends of which are connected by vertically-swinging levers l to the lower part of the table, as shown in Fig. 11, this arrangement permitting the arms L to rise and'fallwith the table and also independently of the same to a limited extent. The ribsl when the table is down form continuations of the wires b', so that the wedges may slide freely upon them. It will be understoodthat when the wedges are thus transferred to the arms they are entirely free from the stationary wiresb b', so that when the table rises the matrices and spaces may both be lifted thereon.

- Above the table, at a considerable elevation above the position in which the line is cornposed, is located the mold M, Fig. 14, which may be of any suitable form, but .which in the present instance consists of a rotary disk or wheel having the mold-cell 'm extended therethrough from front to back, the wheel being supported by a shaft m', mounted in suitable bearings in the frame. After the composed line is .secured in place on the table the latter isl lifted until the matrices and spaces are pressed tightly against the under side of the mold-wheel and across the moldcell, so as to tightly close the latter on the under side and present the selected characters in: front thereof, as represented in Figs, 12b and 14, this closing action being essentially the same as in the numerous patents heretofore grantedv to me. When the comtoo IIO

posed line is lifted and presented to the mold,

as just described, it is necessary that the outer elevated ends of the' wedges shall be permitted to fall until they stand in line with ther matrices. It is for this reason that the arms L, Fig. 15, are .connected to the levers Z and sustained by the springs Z in orderl that they may descend and lower the outer ends of the spaces from their original position (shown in Figs. 1L andl) until they rest flatly upon the table, as shown in Fig. 14. As the rising table I lifts the upper edges of the matrices and spaces against the under face of the mold the spaces are depressed at their outer ends until they losetheirinclixicd relations to the matrices and stand inline therewith, the arms L of course sinking at `the sametime. While the spaces are in this position, as shown in Fig. 14, they are moved 'inward endwise to effect the justification of the line. After the slu g or linotype has been east the table is lowered and is followed by the end of the matrix-guide u' until the latter reaches the sustaining-pillar at the right of the' main shaft, as shown in Figs. 1 and 1l. Meantime and before the table falls away from the guide u the arms L sustain the outer ends of the spaces in an elevated relation to the table, so that the slide or carrier U may ride under the spaces and gain access to the', upper ends of the matrices. At or prior to this time thealining-blade i is lowered out of the notches in the matrices; which are thus allowed to slide down endwise until their upper ends are brought into the common line by reason of the ears on their underv sides at the upperends coming in contact with the blade. After the engagement of the carrier-slide U with the teeth in the up per ends of the matrices the alining-blade sinks until it isflush with the table, so that the matrices may be carried upward thereover to the distributing mechanism. In order to release the matrices preparatoryy to their realinement, as above stated, the spaces are withdrawn endwise by the arms L. After the matrices are-removed from the table by slide U the table sinks to its original and lowest position.

When the composed line is presented to the mold, as above described, it is necessary that kthe spacing-wedges shall be thrust inward until the line is vjustified or tightly spaced -out .to the predetermined length. This action of lthrusting the wedges inwardthrongh t-he line from opposite directions is effected by the arms L L, which are connected (see particularly Figs. 14 and 15) by links Z5 to opposite ends of a cross-arm li onarock-shaft l5,which is seated -in the table and provided with a weighted lever Z6, which on being released causes the arms L to swing inward toward each other, carrying with them the wedges.

'lhe advance of the arms is controlled and their separation to withdraw the Wedges ef fccted at the proper time by a rod Z7, connected to an angular lever Z8, one end of which is acted upon by a cam-wheel Z9 on the main shaft. The wedges are preferably advanced te justify the line as the matrices are being closed against the mold by the rising action of the table, and they are lpreferably retracted to release the matrices immediately after the casting action as the descent of the table begins; but the time of these movements may be changed so long as they do not interfere with the other actions of the machine.' The' rising` and falling movements of the table are leffected at the proper times by a lever a?, pivot-ed to the main frame and provided with a roller or projection i5, riding on a suitablyshaped cani i on the main shaft Z, mounted Figs 10, 12a, 14, 15,16, itc.

longitudinal relation byrib c', is bshifted to the table, the relation of the matrices must -be maintained, and this must be continued until the line has been raised to the mold and the casting operation completed. For this purpose the rising,r and falling blade i9. is mounted in a slot in the table, as shown in During the assembling of the line the blade stands above the table, as shown in Fig. 1G, forming a continuation of the fixed rib c'on thebed, so that when the completed line is shifted endwise from the bed to the table-the blade i9 enters the notchesin the under edges of the matrices and prevents them from moving endwise. The blade remains in its elevated position during the rising movement of the table, during the castingaction, and until the table has descended part -way to its original position, to the level at which the matrices are engaged by the slide or carrier U, which elevates them to the distributer, as will be presently explained.

In order that the risingr and falling'movement of the table and of the blade therein may be eiected by the lever i* mentioned above, the aliningblade t is attached to a plate il", mounted in the lower part or standard of the table and having a limited sliding motion up and down therein. It is to this plate 1 that the end of the lever i4 is conneeted. Through slots inthe table-standard a fixed cross-bar i2 is extended, its outereuds being held by arms connected to the main bed-plate, as shown in Fig. l. When the ta-` ble is down in position to receive the matrixline, as shown in Figs. 10 and 11, the plate 'iw rests on and is sustained by the bar 20, so that the alining-blade is held above the table-sur face in position to engage the matrices.

The links or levers Z' are mounted on pivots in the table-standard, and their inner ends engage the plate 10. Acting under the iniiuence of the springs l2 they tend to depress the plate 111, and thereby draw the aliningblade i down within the table. As the table completes its ascent to the casting position the spacing-Wedges B at their` outer or elevated ends encounter the under side of the mold-wheel, as indicated in dotted lines in IOO Fig. 11, so that as the table continues to rise f away from the mold-wheel after the casting action the springs Z2, through the'levers l and arms' L, again raise -the outer ends of the spaces above the table and above the level of the matrices, as shown by dotted lines in Fig. 15, the levers Z' at the same time and by the same motion drawing the plate Lw and -matrices being thus arrested'in their sliding motion have theirupper ends brought into a common line in order that they may be engaged by the distributer lifter or slide U, presently to be described, before the plate 1'. disappears within the table.

It will be perceived that the sinking motion of the blade 219 iscaused by the springs Z2 act ing through levers l and'that the latter are inturn controlled through their arms L and the spaces B bearin g against the mold M. As the table sinks away from the mold with the matrices the arms L for the time being remain at rest so far as vertical motion is concerned and so long as the outer ends of the operation of the spaces bea-r against the mold'. The levers l' are inthe meanwhile sinking at their inner ends with the table. It follows that theseinner ends will lower the slide and its aliningblade in" relationv to the table.

It is to be noted that although lthe lever i4, actuated by cam t'operates through the plate 'im to` raise and lower the blade and the table the motion of the blade within the table is modified or controlled in part by the levers t', actuated at one time by the springs l and held at another time by the opposing arms L and the spaces thereon bearing against the mold. The parts' are so timed and proportioned that the matrices are released and permitted to realine themselves, and the carrier U is permitted to engage them before the blade i9 sink wholly within the table, and that after such engagement the blade completely disappears, so that the matrices may be carried over it toward the distributor.

In order that the spacing-wedges may not prevent the rising action of the alining-blade, they should be made of less width vertically than-the matrices, so that they may rest upon the aliningblade',.which will support them in contact with the mold, as shown in detail in Fig. 14.

While the mold is closed on the under side by the matrices and spaces, it must be filled with molten metal in order to form the linotype. This is effected by means of a meltingpot N, Fig. 14, hinged on a'horizontal pivot at its lower outer side to the main frame, as shown in Figs. 10, l1, and 14, that it may swing to and from the top of the mold, and heated by any suitable burner n2, so that a large supply of molten .metal may -be maintained therein. The pot is provided with a month adapted to fit over and close the upper or rear side of the mold-cell and is provided with a deliveryoritice n', communicating with an internal pump n3, so that by the pump the molten metal may be forcibly delivered iuto,the mold-cell, in

which it solidies and forms a bar or linotype bearing on its edge in relief-the characters presented by the matrices which are' for the time being in front of the mold.

After the casting operation is finished andl the matrices removed from the mold, ashereinafter explained,'the mold-wheel makes 4a partial revolution and presents the linotype in front of the sliding ejector-blade R, Fig. 11, which is then frced downward by a cam r, so as to drive the linotype before it'out of the mold.. The rotation of the mold-wheel andthe movement of the ejector occur alter- -nately, as in the linotype-machine now in general use, the intermittiug rotation of the moldbeing edected by an ordinary stop-motion pinion me, mounted on anfordinary moldshaft and engaging an ordinary mutilated or speed-motion gear m21 on the upper end of the main shaft Z, as shown in Figs. 1, 10, 14, and15 and in the-diagram 14h adjacent to Fig. 14. This gear is not in itself an essential part of the present invention, as itis Swell known in the art and is similar in construction and operation to that now used for ldriving the mold-wheel in the commercial linotype-machines, in which'the wheel is rotated and the ej ectorreci procated alternately.

Motion ,may be communicated to the machine from any source through any ordinary means known to the mechanic-for example, a pulley on the lower end of the main shaft Z, as shown in Figs. l0, 11, l5, re-this feature forming no part of the invention.

The mold may be rotated, the melting-pot moved to and from the same, and the pump actuated by devices of any suitable character, as these parts 'are not of the essence of the invention. I recommend, however, the swinging of the pot to and from the mold by means of a rod n, (see Figs. 1 and 10,) lifted by a spring a7 and depressed at suitable times by a lever n, acted upon by a projection n.13 on the guide of the table, so that as the table rises to present the matrices to the under side of the mold it acts to swing the Vpot against the upper side of the mold. The

pump-plunger is operated by a lever n.9, Fig.

14, depressed by a cam al and elevated by a spring n, as shown in Fig. .14.

After the casting operation is completed it is necessary to distribute the matrices and sp ce's, returning the former to the upper en s of the magazine and restoring the latter to their sustaining-wires. This is effected in the manner following:

A slide U, Fig. 3, having its lower end provided with teeth uto engage within the upper toothed ends ofthe matrices, is arranged to slide upward and downward in thepivoted guide u', so arranged that when the guide completes its downward movement its teeth will enter and engage the entire line of matrices, so that on again` moving upward the slide will carry with it, through the guide u', all the matrices to the distributing devices at the top of the machine, leaving the space- IOO
