SPEo FmA riQN forming part or Keissued Letters Patent No. 11,393, dated Novemb'er as, 1893. QriginalNo.-345,525, dated July 13,1886. Application forreissue filed August 10,1893. sextant. 482,872.

To all whom it may concern.-

Be it known that I, 'OTTMAR MERGEN- THALER, of Baltimore, in the State of Maryland, have invented certain new and useful 5 Improvements in Machines, for Producing Type-Bars and Matrices for Type-Bars, &c., of which the, following is a specification.

This invention relates to thosemachine's in which, through the medium of finger keys,

to types or dies having individual letters or charaeters'thereon or therein are. assembled temporarily in line either to form matrix-impressions from which to cast printing-bars or to co-operate directly with a mold in which 1-5 the bars areformed. In operatingsuch machines, whatever their form, it. is found, as in type-setl-ing-by'haud, impossible to determine in advancethe spacing required .between words in order to have the characters fill out the space allotted for the line, and this not only because of the varying width of the characters, but because of the necessity of following the accepted rules as to the division of words, 850.

:5 It is theparticularaim of this invention to provide an automatic mechanism by 'which a proper and uniform spacing or justification may be instantly effected after the designated characters are assembled in-line.;

To thisend it consists in the. peculiar con struction and arrangement of mechanism herein described for distributing, inserting properly between the aligned matrices, and simultaneously operating a series of expam 5 sible space-bars which act to elongate or j ustify the line to a predetermined limit. The

space-bars'consist each of two wedge-likeportions tapered in opposite directions.

I do not claim, broadly, a space-bar con- 40 sisting of, twotapcred members, nor theparticular matters covered by application Serial 7 No. 181,576, filed November 2, 1 885.

In the accompanying drawing-s1 have shown m-y inv-ention applied to the machine fior casting type-bars set forth in Letters-Patcntot the United Statesgranted-to me on, the 'fld day of March, 1885, No 313,224, in which a series of parallel reciprocating bars,

each provided inthe edge with series of intazlio- I characters, co-operate directly with a. mold,

closing its side in such manner as to produce type on the edge of the bar formed in the lIlOfld. It is to be understood, however,,that the improvement is also applicable to a machine having cameo characters on the bars for producing stereotype matrices, .s represented in Letters-Patent of the United States, dated FebruarylO, 1885, No. 312,145, and genorally to any and all machinesin whichdies, types, or matrices representing letters, char- 6o acters, or symbols are temporarily assembled in line to produce impressions in or char-' acters upon any material, whatever,

A second part of myinvention, relatirg more particularly to machines in which the I direct casting operation is performed, has reference to a device for confining the parts or, sections of the mold during the castirg operation and subsequently releasing them that the mold may be opened for thedischarge of 710 I the casting.

A third feature of the invention relating to the same class of machines consists in pe- 'culiar devices to assemble the priuting-bars or type-bars automatically in regular order as they are delivered from the machine.

In the drawings I have represented a smachine the principal parts of which are identical or substantially identical with those described 'i n Lettelrs-Patent of theU-nited States, 8o"

No. 313,224, before'alluded to, to which pat-' ent reference may behad for a detailed de-" scription of those parts uot described herein.

In ordcrthatthe detailsofthe mechanism may be more readily understood I have rep resented in the drawings and will first describe, diagrams illustrating in a general way the relative arrangements ofthe matrix-bars and space-bars, and the manner in which the lattcr'are adjustedaud insert ;d between the former.

Figs. 1,2, 3, and {i are the diagrams above referred to. Fig. 5 is a side elevation of the main portions of the machine, the parts being represented in vertical'section on the line 5 2-2 of Fig. 7. Fig. 6 is a vertical central :sedtiddthrough the main portion of the machine-"from .front torear on the lin e 1.-1 .0E

the'part's adjacent to the casting mechanismbeing represented in vertical section 'on the line'3 3 of Figs. 5, 6, and 7. Fig. 9 is a front elevation of the matrix-bars and space-bars as they appear after the .justificatiou of the line, the parts being in position for the ca'st ing operation, ,together with a sectional rep-- resentation ofv the clamps by which the bars are confined laterally, and the bar for gaging or determining the length of the-line.- Fig... 10 is a topplan view showing the devices for,

, transferring and supporting the spacing-bars,

together with various attendant parts. Fig. 11 is a similar vie'wot the parts as they ap-' pear at an intermediate stagein thedistri- 'bution. of the spacing-bars. Fig. 12 is an.

Fig. 13 is an elevation, looking against-the oppos'ite endof said frame, showing the mechanism for determining the adjustment ofthe respective slides by which the distribution of the space-bars is seen-red. Fig-14 is'a verti? calsection throughv the middle of the ma" chine from front to rearon the line-1 1 of Figs. 7, 8, 10, and 11,.showing more particularly the spacebars and their attendant'parts.

Fig. 26 is a. view illustrating the manner in whichthe controlling-cam may be applied in place of the weight-to impart a. positive motion to'the'device by whichthe space-bars are advanced.

Referring to Figs. 1 to 5, B B represent the matrix-bars suspended side by side,'each bar provided at its edge with a series of characters, and arrangcdto descend independently of the others, so that'ei ther of its char-- ac'ters may-be bro'ugh to the aligning-point, as in the original machine. v ('3 C are the laterally-aeting clamps,be-

tween which [the matrix-bars are confined;

Fig. 17 isa when in action, and by which the-length of the line is in part determined.

D is the-mold in which the printing-bars are formed, having its open side presented towardthe matrix-bars, so that the-selected and aligned characters out'he latterT-will temporarily close its side.

E E represent the tapered space-bars to which the present invention relates.

In the normal position of, the partslhe m'atrix-bars are suspended at uniform heights,

with their lower ends above the. mold and above 'the tops of the space-bars, which latter, hang with their narrow ends uppermost, side by side, in a compact group at one side of-the: machine, out of the path of the matrix-bars.-

After the letters or characters 'to appear in the'line and the places for .the intermediate* spaces in the line have been determined by the operation of the finger-keys, as usual, and whilethe mati-ix bars.are still in, their elevated positions the space-bars are shifte'd'lat-- erally beneath the matrix-bars, as shown in.

Fig.2, and distributed thereunder, so that each space-bar'stands below apo'intat which a space is to occur i'nthe line. 'AfterZ't'his distribution of the space-bars"the 'matrixbars descend, as usual, tobring theirseleeted characters to'the aligning-point opposite the .mold-, and in so doing they pass between the J space-bars, as shownin Fig. 3. To facilitate this entrance of the matrix-bars those hav#. ing the wide ends are beveled or pointed, as"

shown. After the matrix-barshave reached their operative positions the space-bars are forced upward positively, -'si multaneou sly, V

and equally, whereby they are caused to force the matrix-bars apart laterally until they fillout the space allotted for the line, at the same time separating the matrix-bars'bet'ween the terminal letters of words, so as to produce unif-orm spacing throughout the line. The

parts thus remain untilafter the casting operation is completed when theyassume'their original positions.

Having thus explained the general nature of my justifying mechanism, I will now explain in detail the construction of the spacebarsand of -the devices by whichthey are justitled and operated, premisingfthat all parts -of' the machine, except the justifyingmechan -ism and other parts'hereinafterspecified, ar'e' Ito.

constructed and arranged to operate in the 1 manner set forth in Patent No. 313,224.

Referring more particularly to Figs. 5, 6,

7, 8, and 9, D represents the horizontal mold,

' and'G the horizontalclamp, which acts on the rear or blank edges of the matrix-bars when;

they are lowered between the clamp and mold, for the purpose of forcing them against the latter Above the clampand mold, on oppo sitesidesof the space into which the matrix-, ,b'ars descend, I place two horizontal parallel rails, H,,.which are'extendedat one end beyo'nd the path ofi-thesaid bars.

. s On andbe-y tween theseraglal suspend a series qt space bars, E, so-that they may be moved laterally. Viewed from the side, each of these bars is of an '1 form, as seenin Figs. 18 and 19, but viewed from the, edge it is of a tapered or wedge-like form, the thin end being uppermost. Each bar has its tapered body portion a made in a separate piece from its T-shaped head Z), and connected thereto by studs or lips e, on the head, entering 'an undercut or dove-tailed groove d, in the body, as in Figs. 17 to 20, so that the body portion may be pushed upward between the matrix -bars while the head remains upon the supporting rails II. A projection on the side of the body limits its .descent and holds itcommonly in suspension from the head, as seen in Figs. 17 and 19. The head diminishes laterally in thickness from the lower to, the upper end, or, in other words, tapers in the op'positedirection from the body, in consequence of which the outer face of the head and the outer face of the body are at all times parallel. This construction avoids the inclination or deviation from the vertical on the part of the matrix-bars which would result from the thrusting of the tapered space-bars between them.

The head and body. of my bar, tapered in' opposite directions and arranged to slide one upon the other, as described, constitute jointly an expansible spacing device, the operative portion of which is always of uniform thickraising and lowering the body, as hereinafter explained. The series of space-bars hangnormallyin their-lowermost positionscrowded closely together at the ends of the rails H, .as in Figs. 1, 8, and 11. The several bars have their heads made of different widths, and

are arranged in the order of'suchwidth, the widest at the side nearest the matrix-harass" guide-s beyond the sides of the main frame,

and in this sliding frame I mount two rows of horizontal transverse slides, J, the inner ends of those in one row'standing opposite those'in the other row, but normally at such distance apart that they may be carried freely past the heads of the space-bars. 'lheseslides are designed, however, to be moved inward, (such of them as circumstances may'require) so that they will, when carried to the left by the movement of the frame I, engage the heads of the space-baraand carry the latter before'them along the rails and beneath the matrix-bars.

To the end that the space-bars may be moved singly and to difieren't points, the opposing slides are moved inward toward each other different distances, the first pair called into use remaining at such distance apart that they will pass the heads of the narrower bars and engage only the last bar having the widest head, the next pair. of slides being adjusted to engage only the second bar, and so on successively.

The variation in the approximation of the different slides is plainly shown in Fig. 10, and their action on the successive space-bars is represented in Fig. 11. r

During the transfer of the space-bars by the slides,- and during the descent of the matrix-bars after the space-bars are in position,

itis desirable to lock the space-bars from turning or twisting on the rails. This is accomplished by thrusting all the slides inward to their limit of movement, after they haveengaged the space-bars, so that the head of each bar will be embraced between two slides on the forward sideand two on the rearside,

as seen in Fig. 11. This final inward move ment of, the slides is effected. by meansof'inclined plates K, attached, as shown in Figs. 10 and 11,to plates Z, herein described, which act against'the outer ends of the slides as they are'carried tothe left by the inovement of the supporting frame I.' l

The first inward movement of the slides that is to say, their adjustment 'to act upon the respective spacebars--is secured by means ence being had particularly to Figs. 5, 7, 8,

10, 11,-12, and'13. Ove'rlying'the frame which carries theslides there is a transverse bar or. head, L, arranged to'slide onzsuitable' gurdes in the same directioiiut'hat-the frameslides,

but wholly independent thereof. Pivoted to the sideof the'head L are two elbow-levers, M and M ,the inner ends of which are jointed together,--while the. outer ends extend downward 'oppesite the outer ends of the slidesJ, so that whenever the inner euds ofthe lever are raised their lower'ends -will-a ct uponthe slides-opposite which theychaneeattire-mo:

. in position to engage the-spacebars, as before explained; The sliding motiou oi the head from right to left'admits of t he' levers being brought into position toast upon the successive slides throughout,thejseries." The.

sliding head is connectedmsherein'after more fully described, by a rigid arm, N, orin any other appropriate manner, as in Figs; 5 and" 7, with the adjusting pin frame-of the origi nal machine, which frame, it will be remembored, moves to the right step by step as the takes of this movement, so that as the suc' cessive keys are operated to set the stop devices for the successive matrix-bars, the leletters M will be presented-in position to oper ate ,on the successive slides, J, the pairs of which latter should equal in number the matrix-barsin the machine. The. movement of the levers M and M to set the slides inward is effected by means of a rod, 0, carried by the lower end of an angular lever or levers, P, which is pivoted to the main frame, and the upper end of which, adjacent to the keyboard, is provided with a finger-key or bar, Q, so that every depression of the finger-key will be followed by the inward movement of a pair of slides J.

' tances.

In order to control the approximation of the dilferent slides for the purpose before explained, I mount centrallyon the sliding head L, in such position as to he carried thereb.) between the inner ends of the slides, a disk or wheel, R, having its peripher composed of two eccentric portions divide into short stops or shoulders, as shown in'Fig. 12. When the levers act upon the first pair ot'slides that is to'say, those at the left of the series the eccentric wheel stands in the position shown in Fig. 5, with its outermost portions. opposite the slides, so that the in ward movement of the latter is limited by their coming in contact with the wheel. After the-adjustment of the first pair of slides the wheel is turned slightly, so as to present a smaller diameter between the next slides, and so on repeatedly, whereby it permits the successive pair of slides to be moved increasing dis- The rotation of the wheel step by step for this purpose is secured by means of a ratchet-wheel, S, mounted on itssaxis and actuated by a pawl, T, carried by'an arm on the axis of the lever N as plaihlyrepresented in Figs. 12.and 13. p

For the purpose of restoring the wheel to 'i r original position at the proper time, its shaft is connected with one end of a coiled spring, U, the opposite end of which is fastened tothe supporting-head. To hold the wheel as it is turned step by step, and prevent it from turningv backward until the proper time has arrived, a second pawl, V, is arranged to engage the ratchet-wheel, as shown in Fig. 13, After the completion of the op eration 'theltwo pawls are automatically released by means ofbeveledstuds, W, secured to the main frame, as seen ;in.Fig. 10, in such. position as to act upon ,and raise the twopawls when their carrying head L is moved to the left to its original position. I A slot and pin, as in Fig. 12, serve to. limit the rotation of the wheel R,whichrece ilves in no case more than half a revolution;

The movement of the slide-carrying frame I is effected atthe will of the operator by means of ahand-l'ever, X, pivoted to the main frame and connected with the sliding frame ,3); means of alink, Y, as shown in Fig. 7. In

(order that this lever may servertheadditional purpose of throwing into gear the clutch by? which the machine is driven,after the slides are in position-I connect thelinbY- with .tth'e sliding {"Qmfi I flit-curler the lgQdlmfl1iranged to slide onthe frame I, and connected with the latter by springs 71. On moving the ing block g, which is pivoted to the link ar- I lever to theleft the slide g and. springs h reof movement,a continued pressure of the lever will overcome thesprings and permit thelever to receive :tcontiuuing movement independent of the frame I, which remains in the meantime at rest. This continuing orsecondary movement of the lever is rendered available for starting the machine by connecting to the 'leveralink or bar, z, the opposite'end of which will be connected with the usual driving-clutch or otherstarting devices,'whichmay be of the same construction as those in the original machine. After the slides have performed their functioncarrying the space-bars to their operative positionsit is necessary to restore the slides to their-original positions in their carrying-frame preparatory to their use in the justification of the next line. To

verse notch, k, as shown in Figs. 5, 10, 11,and

this end I provide the slides each with atrans- 14. In the frame directly over the place 00- cupied by the slides when they are in their operative positions-I suspend two pivoted blades, Z l, extending-transversely to the blade acting to move the corresponding row or series of slides outward to its original position, as indicated by the dotted lines in Fig.

swing outwardaway from each other, each 14. In this way the slides are disengaged from the heads of the space-bars, so that the i slide-carrying frame may berestored to its original position outside of the main frame. The openingact'ion of the, blades when they spring, p, as shown in Fig. 14.. Their closing action is secured by means of a headed rod, q, extending from one of their arms, 0', upward loosely through an ear on the rising and are released is secured by means of-aspiral falling head,-s, by meansot. which the manni-v bars are lifted to their normal positions, as in the'original machine, this head being the same them by the movement of the frame I. When- 'as that lettered-P in Patent No.'313,224. At; the instant, therefore, that the matrix-bars complete their rising motion the head saets through therod q, to set the blades in posi the d'escent of the head .9 and of the matrixa bars commences, the rod (1 is released, so that the spring may; spread the blades. When ..I, they carry the plates upward-in such ,positiomas topermit the slides topass therel by as they moyedgwtm metn'mi'a I.

the plates lare separated to retract the slides .make use of a heavily-weighted lever,

For the purpose of forcing the space-bars upward after they have been distributed, I

mounted in the main frame, and connected at one end by a link, it, or otherwise, with a ends of the space-bars, driving their-tapered bodies upward between the matrix-bars, as before explained.

In order torelieve the space-bars from the action of the yoke and lever, to the end'that they may descend at the proper time, I mount on themain. shaft of the machine a cam, w, which acts on a stud or roller on the lever t.

This cam will also'serve to control the movemerit of the lever when elevating the yoke and space-bars, so as to prevent the shock and strain which would result from a sudden release of the lever. I

For the purpose of drawing the space-bars downward with certainty at the proper time, I providea Weight,0'c, slidingin'vertical guides extending downward from the main clamp G or from any other suitable part of the' machine. This weight bears upon and is lifted by shoulders or enlargements on the lower ends of the matrix-bars, so that it tends eonstantlyto urge them downward. The

weight a: and the yoke 11 are both terminated at one side of the space which the group of type-bars occupied previous to the com mencement of the operation, as shown in Fig. 9, in consequence of which the yoke and weight.

act only upon those space-bars which are carried over laterally to an operative position, those bars which are .not called into use remaining arrest.

In order to insure the entrance of the ad justed or distributed space-bars at the proper "points between the matrix-bars, I find, it advantageous to lift the space-bars into engagement previous to the descent of the matrixbars; but it is to be understood that this is not a necessary feature. This action-is secured by giving'the cam 10 such form that it rails I], so thatjthe bars may move edgewise' withthc matrix-bars toward theface of'the mold when the clamp G is brought into action against the rear edges. the heads, which is very slight, is limited by rods or equivalent stops, y, as shown in Fig. 6.-

In order to lock the weighted lever and hold the yoke r positively in its depressed position' The rising motion of during the time that it is not required for use, I pivot to the yoke a pawl, .2, arranged to en'- gage with a toothed bar, a, extending downward from the main clamp G. As the yoke descends; this pawl slides over and engages with the toothed bar.

In order to release the pawl at theproper time,it is provided on one side witha pin, b, which enters a vertical groove in the edge of the fixed bar 0', located adjacent thereto. W hen, therefore, the clamp is moved forward toward the matrix-bars previous to the completion of the casting operation, the bar a disengages the pawl, leaving the yoke and weighted lever free to rise and actuate the space-bars.

As the attendant is liable to commit an error by striking the space-key and adjusting" the slides J at an improper time, provision must be made for correcting such error. This provision consists simply of two inclined blocks, d, attached to the guides'or ways on which the slide-carrying frame I is moved, as plainly-represented in Figs; 7, 10, and 11. If 0 it be found that improper slides have been adjusted, the operator has only to throwthe lever X to the right beyond its normal position, thereby moving the frame I to the right, and causing the inner ends of the slides J to 5 be. carried over the inclined faces of the blocks d' d', which have the etfect of forcing them all outward totheir original positions,

so that the operation may be commenced anew. v '100 After the casting operation is completed and the matrix-bars elevated, it'is necessary to restore'the space-bars laterally to their original positions preparatory to the corn mencement of the next line. This is accomr05 plished by means of horizontal rods e, connectedtoa hand leverf', on the left of the 'cro'ssed,as shown, so that as the blades ll are separated'to retract the slides the plates at n? are approximated. so as to bear edgewise on the matrix-barsand bring the latter in line,- 12o so-that they may descend easily and without binding between the guide-rails H and between the mold and clamp. It is to be un derstood, however. that .the plates-n 'n' are not a necessary feature of the machine,'and :25 that they may be omitted or replaced by other devices having a like function.

It is tobe particularly understood that in my machine the several space-bars are .actuated positively and simultaneously, and to I30 precisely the same extent, so that a uniformity of spacing in the line necessarilyfollows.

In this regard myconstruction is far superior to one in which the space-bars are caused or her that they may be separated endwise to permit the delivery of the completed bar.

In operating the mold, it is found in practice that if its surfaces be fitted with suificient closeness to prevent the leakage :of the molten metal, they areli-able to bind when expanded by the heat. To avoid this difliculty, I provide means whereby the two-parts may be pressed together-vertically when in operative position, but relieved. from such pressure when the mold is to beopened, These pressure devices may be modified in form and arrangement; but 'I recommend as a simple and satisfactory means for the purpose a lever, 12', pivoted to the mainframe or other suitable part of the machine, and arranged to act at one end on top of the mold, as plainly showrh in Figs. (Sand 7, its opposite end being ele-; vated at the proper time bya bar, q, attached to the rear sideof the rocking melting-pot '2', which isvpivoted at s", as in the original ma-- chine. A spring, 15-, is attached to the finder side of the lever to bear onthe operating-arm, asshown in Fig. 6. \Vhen the pot tips for-' ward to present its mouth against the mold, motion is .transmitted through the spring to the lever, and thus the two parts of the mold forced tightly together, 3 :i Another feature of my invention relates to improvements in devicesfor adjusting the matrixbars to bring the required characters in accurate alignment. In practice it has be'n'found that after the stop devices have acted to align the characters it is-desirable to make use of special mechanism to insure a very accurate adjustment of the aligned charactors. {For this purpose, I use, as-in the originalmachine, an aligning device extendin'gacross the entire series of bars andenterin'gnptches in their'rear edges; but instead ofusinga single biade, as in theoriginal m'a-' chine, I'employ two co-operatin'g blades, 11/ and a), lying horizontally-in the main clamp,

G, as plainly shown] in .Figs. 6, 7, 14,24, and

25. The two blades arefhinged together, and are movable forward and backward in the clamp, so that they may be projected beyond its face to'ente'r the notches in the: bars, as in Fig. 25, or retracted, as in Fig. 14, to permit free vertical movement of the bars. The forward and backward movement of the blades is efiected by passing the lowerblad'e,

u',loo'sely through a rock-shaft, w, and connecting therewith springs, yflwhich urge the blade forward, and by a vertically-reciprocating'bar, a, which plays through aslot in the eled toretfract When the bar, 2!

,is depressed, the blades are thrown forward by the springs to engage the matrix-bars, but the elevation of 2' draws the blades out of engagement. The rock-shaft is provided, asv shown in Figs. 8 and 24:, with a depending arm, 04?, having in the lower end an inclined surface, 00 acted upon at the proper time by bar clamps C and one of the mold-sections, as

the clamp and mold,it strikes the inclined surface a; and causes the rock-shat t to tip the forward edge of the plate to upward toward its companion 1:, which latter isprevented from rising by reason of its solid bearing against the clamp G. As the two plates are engaged in diflferent notches-of the matrixbars when thus closed together, it follows 'of the bars between them, thus bringing-the notches, and consequently the characters on all the bars, into accurate alignmentf'The bar 2, for retracting the blades is pivotally connected to an operating arm, a attached whereby the blades are permitted to advance and engage the matrix-bars before theyare closed together.

In practice it is usually desirable toadjust the machine for thecasting of bars of uniform length. Asthe mold is susceptible of beingclosed to produce shorter bars, and as with the driving devices, as in the original -machine, by springs which tend to close the mold beyond the proper point, it is desirable to provide a positive means for stoppingthe clamps and the mold whenever-they 'reachthe predetermined position; This positive-stoppageis advantageous in that itinsures a line the matrix-bars from the possibility of re spa'cing-bars from beingforced'upward betw'een them.

It will be observed on reference to the drawings herein and particularly in Figs. 19 and 2i tliat the head of the 'space-bar-is cutaway'in' one ed ge, so as to reduce its width at this point below the width of the matrix-bar B. Thus it is that the notched end of the clamping jaw C 1s enabled to straddle the inactive spacefi'bars,

In order to admit of the clamps acting to confine the matrix-bars closely, should it happen from any reason that their aggregate width is insuflicient to produce a line of full width, I connect the gage-bar b to the clamp by means of a locking-pin, 0 held in engagement by a spring, d, and on the rock-shaft which closes the clamp G, I pivot a. trip-lever, As the clamp G. completes its inward movement, the trip device acting against the beveled head of the pin 0 lifts thesame out of engagement, leaving the gage-bar free to The bars produced by this machine are used. by assembling them inthe order of their production, side by side, to constitute a solid form. I now provide the machine with automatic me us for assembling the bars, as shown in igs. 8 and 22.-' At one side of the frame I arrange an inclined table or galley, 9 having a flange or rail at. the lower edge. Above this table I fix a chute, h usually of asingle piece of sheet metal. The upper end of this chute lies immediately beneath the point atwhich the mold delivers the completed bar and it is of such form as to allow the bar to fall sidewise thereon. Toward its and ihcr'easedin height, its inner surface bemg g1ven a spiral or twisting form, so that as the bars slide downward thereirnby grgavity.

they are 'turned so as to prese t theirfirims 'ing-edges uppermost and delivered in this position endw-ise upon the galley. On the galley I place a reciprocating head or pressure device, 2' actuated by a pitman, 9' carried at oneiend by an eccentric or-crank, secured to an extension of the main shaft. In advance of the pressure device I arrange a yielding head or support, 1*. As the bars descend in succession from -the chute, they:

are forced forward one after another toward thesnpport Z which is gradually advanced as the bars accumulate behind it. The head 1' retreats at each movement a sufiicient distance to permit thenext bar to enter between it and the bar last added to the form. v

Operation: The various parts stand nor.- mally injthe positions shown in Fig. 8. The mold andtheclamps being open, the matrixbars are. elevated, the spacesbars assembled in a group at one side, and thealigni-ng-plates retracted. The operator d epresscs in proper succession the keys (lesignatingthe characters which are to appear in the line in precisely the same manner as in my original machine. The operatioin of the finger-keys is also followed by the lateral m'ovemenhofthe jadjusting-pin frame step by step, in he orig inal manner, and thislin turn carries t ehead the successive slides J. \Vhen, therefore, the space key is operated, the corresponding slides, J, are thrust inward successively different distances, the motion being limited by wheel R. At the completion of the line the adjusted slides therein, carried to the left, so that the slides take up and distribute the spacing-bars, at thesaine time engaging beneath the plates 1 Z,l which subsequently effect their retraction. The machine is now between the matrirc-bars, which latter then descend to their operative positions, the spacebars being at the same time dropped to their and disengaged from the space;bars and rethe frame by the movement-pf their carrying frame. At or about -this time the lateral their movement biiig limitednby the gagebar, and immediately thereafter, the spacebars ascend in unison, thus completing the justification of the line. The casting opera: tion isnow performed in the original manner, after which the clamps release thebars, the space-bars descend, the matrix-bars are elevated, and finally the space-bars moved to the right and grouped in their original positions. W'hile I prefer to have the slides J move trix-bars,- it is manifest that they would op- ..desired, theoperating-levers and other parts being varied 'inf position to correspond.

While I'have shown my invention in con- :nection with a machine having the reciprocating matrix-bars, it is to be understood that it is applicable in the same manner and with the same efiect in a machine having disconnected dies 'aiid mechanism to assemble them in line, as represented in my LettersPatent of-the United States, dated May 12, 1885, No. 3l7,828,issued'olii an application filed on the 21st day of'October, 1884, Serial No. 1%,128. In plage of the weighted lever to advance the space-bars'I employ a lever operated, as in Fig.26,'by the controlling-cam, which will be grooved to re'ceive a stud or roller on the side of the lever. When this device is used, the lever and space-bars will be moved in a positive manner. As the throw of the cam is invariable, but the distance to which the space-bars must be advanced is variable, I connect'the leverwith the head '22 for L, with its levers M and M, to the right past.

In the event of their being required to move but a short distance they will wedge fast between the matrix-bars and cease their motion,whereupon the sprirg will yield to permit the continued motion of the lever and cam.

It is to be understood that whether the I weight or the spring be employed to operate I vided at its lower end with the Shoulders or the space-bars they will exert sufficient force to advance the bars tightly to their places under the conditions encountered in practice, so that the bars are, in fact, operated with a positive motion. I

I believe myself to be the first to operate a series of space-bars in unison, and to force them forward untilthey have spread a line of matrices or dies tightly between the confining-clamps or other confining-device; and .it is to'be distinctly understood that. inyinvention is not limited to the precise details of construction to this end.

It will be apparent to the skilled mechanic that the same mode of action may be secured by devices the details of which may be variously constructed;
