The present invention relates to improve,- ments in typographical machines'ofthelgeneral class shown and described in ,U.:S. Letters Patent No. 436,532, granted September 16,1890,to O. Mergenthaler, wherein matrices stored in a magazine are deliveredther'efrom selectively under control of a keyboard and are assembled, together with spacers, into lines which are presented before a mold and type bars or slugs are cast therefrom, each assembled-line of matrices and spacers being usually presented once to the mold for the casting of a single type bar or slug therefrom, after which the matrices and spacers compos ing the line are distributed or returned to their places of storage ready for reuse.

The primary object of the present inven tion is to provide simple and easily. set means whereby any one or more of the assembled lines of matrices and spacers can be presented to the mold a plurality oftimes in succession to cast a plurality of duplicate or similar type bars or slugs therefrom automatically or without the necessity of setting the machine into operation'througli' manual move ment of the usual controlling lever each time the line is presented for a cast. 7

A further object of the invention is to provide recasting means for machines of this class which is capableof being set selectively to cause the machine to operate through any predetermined or desired number of casting cycles, according to the number of similar type bars or slugs to be cast.

To these andother ends, theinvention con.- sistsin certain improvements and combinak' tions and arrangementsof parts all as will be hereinafter described, the features of novelty being pointed out particularly in the claims at the end of this specification;

.,The ,present invention, is applicable enerallyjto typographical machines of the class in. which, during normal; operation ofthe machine, ,a cast is. made from eachline'of assembled matrices and; spacers after which theinatrices andspacers composing the line are distributed or returned to their usual 8 places of storage, following which another castis made from another or different assembled li'ne'of matrices and spacers, so that one type bar or slug will ordinarily be cast for ea'cli 'line of matrices-and spacers as- 9 sembled in the machine. The Mergenthaler 'patent here'inbefore referred to shows and'describes a machineof that class, and the presderstoodfthat theinvention is not restricted to the precise constructionshown since equivthe scope of the claims.

In the present instance, 1 represents the usual so called assembling elevator in which the matrices and spacers to formeaoh line are assembled, 2 represents the usual so-called delivery channel, 3 represents the usual socalled first elevator having front and rear.

'12 represents the usual so-called transfer slide which operates, while the first elevator is in its uppermost pos1t1on,-to remove the line of matrices and spacers from the first elevator, after a cast has beeninade from such line, to the usual transfer channel 13 from which the matrices are lifted'in the space band box 14-.

usual and well known manner for distribu tion into themagazine from which-they were drawn and spacers are returned to the usual The delivery slide 10 is operated by a lever 114 and the firstelevator is reciprocated by a lever 15 which is connected to the first" elevator through the medium of the usual spring cushion '16.

The first elevator and the delivery' and transfer slides, in machines of this-type,are operated in the proper sequence by a main cam shaft 100 which causes a cam 101 cooperative with the lever 15 to operate the first elevator, the cam shaft as-islwell known, being driven through the gears 102 from the main clutch 103 of the machine and, during the normal operation of the machine, is stopped, after completing each revolution representing a complete cycle of operations, by the engagement of a pawl 18 pivotally mounted on a cam 17 carried by the cam shaft with the usual vertical stop pawl 19 which is mounted on a vertical shaft 20 and controlsthe main clutch, a starting pawl 21 rotatable on the shaft 20 being arranged to dislodge the pawl 18 from the stopping pawl 19 and thereby cause engagement of the main clutch and rotation of the main camshaft to initiate the next cycle of. operations. The

starting pawl 21 is connected to a dog 22 which bears upon a pin 23 carried by aforwardly and rearwardly reciprocatory bar 2 1 which acts on the clutch controlling lever 104 and is connected to the usual starting lever 25 by a toggle 26, pulling of the starting lever 25 forwardly or into the position shown in Fig. 5 causing the starting pawl 21 to dislodge the pawl 18 from the stopping pawl 19 and thereby setting the main cam shaft of the machine into operation, after which the starting lever25 usually returns to its nor- .maLrear position so that the pawl 18 carried by the cam 17 will engagethe stopping pawl "19' and" cause d sengagement of the main ferredto and -U. S. Patent No. 1,194,937, granted Aug. 15, l9l 6, to WV. E. Bertram, to

which -reference is made for a detailed explanation of these parts of a inachineof this class.

The means provided by the present inventionfor enabling a plurality of similar type bars orslugs to be cast from: any assembled line OfTlIELtIlCGS comprises, as shown in the present instance a lever 27 whichis pivoted lntermediately of its ends to the front of the vise cap '7 by a screw or other pivot 28, its upperendextending to a position in front of the line delivery slide 10 and forward of the path of the front jaw 4 of the :first elevator and its lower end extending preferably to a point near the lower end ofthe vise frame 6. The short line transferfinger 10 of the line delivery slidecarries anarm-29 which'is pivoted thereon asbya pivot screw30 sothat this ar m may swing forwardly into a position which will bring it into the pathofthe lever 27 as shown in Fig. 2, or said arm maybe swung upwardly into'a position where .it will clear the lever27, a spring-pressed locking detent 30 being provided for holding said arm in operative position. When the arm 29 isset in the operativeposition'so that it projects forwardly from the line delivery slide, it will engage'the upper end of the lever 27 during the final portion'of :the line transfer movement of said slide and will swing the lever 27 from its normal position-as shown by the dotted lines in Fi 1 into the full line position shown in that figure, but when the arm 29 is swung upwardly'into an inoperative p'os'ition,thelever27 will berunafiected by the movement of the line delivery slide.

The lever 27 is pivotally connected at a point below its pivot-28 to a link 31 and this link ispi-votall-y connected to the middle pivot 32of a toggle composed of links 33 and .3 1, the toggle link 33 pivotally engaging the t me;

pivot 35 on which the starting lever25 mounted and which slidably guides the bar.

24, and the link 34 having a slot 34 at its forward end which pivotally engages a pivot pin 36 which is fixed to an extension 37 which projects forwardly from the starting bar 24 so that the toggle links 33 and 34 will not be straightened by thepulling forwardof the starting lever 25. While the lever 27 occupies its normal position as shown by dotted lines in Figs. 1 andv 5, the toggle links 33 and 34 will be, in the flexed or broken position as" shown by the dotted lines in Fig. 5, but movement ofthe lever 27 into the full line position shown in Figs. 1, and 5 will straighten or lock the toggle links as shown by the full lines in Fig. 5, thereby locking the starting bar 24in its forward position after being "pulled forward by the starting lever 25 and holding the startingpawl 21 in'a position to prevent lodging of the pawl 18 on the stopping pawl 19 so that the cycle of operations of the machine will be repeated. While the toggle links 33 and 34 are flexed as shown by the dotted lines, thestarting pawl 21 will clear the pawl 18 so that the latter will engage the stop pawl 19 and thus arrest the operation of the machine after it completes a cycle of operations, but while the'toggle links 33 and 34 are in straightened or locked position as shown by the full linesin Fig. 5, the starting pawl 21 will be held in the path of the pawl 18 so that the latter will pass the stopping pawl 19, so that the main cam shaft and the mechanism operated thereby will continue in operation, after a cycle of operation has been completed.

Means is provided for automatically stopping the. machine after the desired number of casts have been made from an assembled line of matrices and spacers. Such means as shown in the present instance' comprises a toothed or ratchet wheel'38, a shaft 39 to which such ratchet wheelis fixed, said shaft being rotatably mounted in the upper end of the lever 27 and provided at the forward side thereof with a'knurled head or handle 40 by means of which it may be rotated to set it, and the shaft 39 carries a suitable number of pins 41 which are threaded or otherwise removabl mounted therein'and project radially there rom as shown in-Fig. 8, these pins and the ratchet wheel 38 being preferably arranged at the rear side of the lever 27 as shown in Fig. 2 and in front of the path of vertical movement of the front jaw 4 of the first elevator. A latch 42 is pivoted on the rear side of the lever 27 by the pivot pin 43, and one end of this latch is connected to a tension spring 44, the other end of this spring being attached to a pin 45 which is fixed to the rear side of the lever 27. The other end of the latch 42 projects into the path of a pin 46 which isfixed to and pro,- jects forwardly from the forward side of the {rent jaw 40f the era elevator. The latch will ,be normallyheld by the spring 44 in upper end of the lever 27 the pin 46 will ride against the under side of theilatch, the latter pivoting idly on its pivot 43 so that the upward movement of the'first elevator does not alter the position of the'lever 27, but during the descent of the first elevator from such an upper position toward'its normal level, which occurs, as usual, after the line delivery slide has returned to its normal right hand position where it is retained until released by lifting of the assembling elevator, as disclosed in said Mergenthaler patent, the pin 46 will bear on the upper side of the latch 42 and will swing it about its pivot 43 into the inclined position shownin Fig.

latch in a direction which will force the upper end of the lever 27 from its operative position as shown by the full lines in Fig.1 into its inoperative position as shown by the dotted lines in saidfigure. v I

' The front jaw 4 ofthefirst elevator also has a pawl 47 pivotally mounted thereon by 1 the pivot pin 48, this-pawl being thus pivoted to swing vertically and having aportion 47 which overhangs the top of the front vise jaw 4 so as to normally support the pawl in horizontal position as shown in Figs. 3 and 4. The free end of this pawl, during the vertical movements of'the first elevator, travels in a path which is in line with a tooth of the ratchet wheel 38. In'consequence, when the first elevator moves upwardly from its normal position, the free end of the pawl will act on the tooth of the ratchet wheel 38 which is in line therewith and will thereby rotate the shaft 39 one step, although when the first elevator returns to its normal level, the pawl 47 will ride idly past the Wheel 38.

V In the construction shown in Figs. 3 and 4, the number of pins 41 on the shaft 39 corresponds with the number of teeth on the ratchet wheel 38, and in consequence, when the le- Its iis

ver 27 is set for recasting from an assembled matically arrested, since the nose of the latch 42 will move into position above the pin 46 when the lever is swung into operative position and hence thesaid latch will not be acted on by said pin during the firstdescent of the first elevator to casting position but the first movement of the first elevator upwardly past r its'normal level following the first casting operation-will cause the pawl47; to iacton the ratchet wheel. 38 tocarrythe pin 41 previously engaged by the latch ,42' out ofthe path of the latch and to bring the next 'pin on the shaft 39 into position-to be engaged by the latch 42-so that on the second descent of the first elevator to casting position, followfrom its operative position shownbythe full linesin Fig. 1 and the dotted lines in Figs. 3

and 4 into theposition shown by the dotted lines in Fig. 1.. 'lVhile-thelever- 27 is in the full line position shown in Fig. '1, the toggle links 33 and 34 are locked as shown in Fig.5, and the stopping means for the machine are thus inactive so that the casting operation may be repeated, but when the, lever 27 is swung into the dotted line position shown in 1, the toggle links and 34 are flexed or unlocked as shown hythe dotted linesin Fig. 5, and the stopping means .for the main cam shaft is then operative tostop the operation of the machine in the usual way when the cycle of operationshas'been completed.

The presentinvention enables any desired number ofcasts to be madefrom any assem bled line of matrices and spacers by varying the number of pins on the shaft 39, it being obvious that by using a smaller number of pins than that shown in Figs? and'4 a greater number of recasts may 'be made automati cally from each'line. For example, Fig. 6 shows-the shaft 39 with three alternate pins removed so that it carries only'three of the pins 41 while the ratchet wheel 38 has six teeth as in Figs. 3 and 4, and'ac cordingto Fig. 6, three'casts will be made automatically from each line during each castingoperation, and by using twojpins,fourcasts will be made automatically from'eac'h lineduring each'cast-ing operation. If desired,'the'sha'ft 89 maybeprovided with ,a single pin, in

' which event, said shaft-couldbe setto cause any predetermined or desired number of casts to be made from a line during each casting operation of the machine before the operation oft-he machine is automatically arrested, the

' shaft 39 being set back after the last recasting operation so that it will then be in positionto recast the next line. I

In order to preventremoval of the assembled line of matrices and spacers from which a recast is to be made, upon ascent of the first elevator followingthe first casting operation, means is provided for preventing ascent of the first elevator to its full uppermost position. Such meanscomprises ascrew 49 ad justably mounted in an arm 50 which projects rigidly forwardly from the lower end of the first elevator slide so that the screw will be in line with and will engage ina seat or recess 51 in the lower end-0f the lever 27When the latter, is set in, its operative position for recasting, as :shown by the full lines in Fig. 1..; The. engagement of'thescrew 49 with the lower endofthe lever'27 arrests the upward movement of the first elevator toward its uppermostlevel,'the excess motion of the elevator lifting lever 15 being absorbed by the spring cushion 16, and theline'transfer slide 12,-is, preferably provided with a latch 52 such as that shown in U. S. Letters Patent No. 1,168,244 granted Jan. 11, 1916, toW. E. Bertram, this latch automatically holding the transfer slide 12 in its retracted or inactive position since the first elevator will not rise sufiicientlyto trip'thelatch. Whilethe lever '27is in its inactive position as shown by the dotted lines in Fig. 1, the screw 49.

will clear the lower end thereof so that the first elevator will be permitted to'rise to its full extent, thereby rtripping the latch 52 and allowing the transfer slide 1 2 to-remov'e the assembled line of matrices and spacers from the first elevator, following completion of the casting operation with respect to such line.

The operation is as follows: WVhile the arm 29 is in its raised'or inoperative position, themachine will operate in the usual way, casting one type bar or slug from each assembled line of matrices and spacers, since the lever 27 will not'be shifted into active position by the movement of the line delivery slide 10," and hence the starting and stopping bar 24 will not be held forward to prevent stopping of the machine in the usual way upon completion of a single casting operatiomand the first elevator will be permitted to rise to its full height for the removal of the line of matrices and spacers therefrom andthe latch 52 will be tripped to allowthe transfer slide 12 to operate to remove the line from'said elevator in the usual way, following the cast ing of a single type bar or slug therefrom.

' hen it is desired to cast'two or moretype bars or'slugs from any one or all of the as sembled lines 'ofmatrices and spacers composed in the machine, it is only necessary to swing the arm 29 on theline delivery slide 10 downwardly or forwardly so'that its path ofmovement during the line delivery stroke ofthe slide 10 will carry it against the upper end of'the lever 27. When the arm 29 is so set, the stroke of the slide 10 in delivering the line of assembled matrices and spacers 1' into the first elevator will swing the lever 27 from the dotted-line position to the fullline position shown in Fig. 1, thereby lock- Mbut the first upward moveinentof theofirst latch 52 will not be tripped but will hold-the delivery slide. 12 against movement to remove the line from-the first elevator, so that the linewill remain therein readytoobe again lowered to casting position for casting another type bar or slug therefrom. At the same time, the ratchet 38 and latch 12 on the upper end of the lever 29 will be'brought into the paths of the pawl 47 and pin'46 respectively on the first elevator'as shown in Fig. 3, so that the descent of the first elevator from its normal or line receivmg position 'to castmg posltlonx for 'the first casting operation will cause the pin 16 to descend without atl'ectingthedatch 42 elevator past its normal or linereceiving position, following the first cast from the line, will cause the shaft 39 to rotate one step which, according to the construction shown in Figs. 3 and 4, will bring'another pin 41 into engaging or blocking relation with the latch 42, so thatthe next following descent of the first elevator to lowerthe line to the casting level for the second rnext following cast will cause the descendingpin' elevator will rise to its full height, tripping the latch 52 and allowing the delivery slide 12 to remove the line therefrom in the usual way, and since the throwing of the lever-27 into inoperative position break-s or-unlocks the toggle 33, 34, the bar 24; willnolonger be held in a position to prevent stopping of the machine and hence the machine, will be stopped automatically after completion of the second casting operation. 1

In order to automatically cast more than two type barsor slugs from an assembled line of matrices and spacers, it is 'onlynecessary to employ afewernumber of pins on the shaft 39. For example,in Fig. G-Wherein the number of pins 41 is equal to only one half the number of teeth on'theratchet wheel 38,

the first elevatorwill moveupwardly past its normal or line receiving position-twicebefore a pin is brought into position to, block the lat-ch 42 andi'thereby cause throwing of the lever 27 into inoperative position upon the third descent of the first elevator to cast? ing position andconsequently, three type bars or slugs will bee-1st fromthe line before the casting operation forthat line-is com pleted andterminated and suchline is removed from the first elevator.

by providingonly one D111 on the-shaft39,

Obviously,

From the foregoingnt will'be seen that the present inventionenables the machineto be easily andquickly set by the operator, while occupying his usual position in front of the machine, to cast either' a plurality of type bars or slugs from'any or all of the matrix lines composed in the machine or to cast a;

singletype barorslug from each matrix line,

asmay be'desired by simply setting the arm 29 on the line, delivery slide accordingly, the

settings of this arm performing thedual function of bringing the recasting means into operation which causes continued operation of the machine until the desired number of casts have been made and also retaining the matrix line inthe first elevatoruntilsuch casts have been completed, whereupon the stopping brought into condition to stop the machine removedfrom the first elevator I 2, V 7 z i V,

The recasting control, it will therefore be will be recast, and if'said arm ispermitted to remainin operative position, the machine will operate automatically to make apredetermined number of Irecasts from each matrix line introduced into the first elevator before removing such line therefrom, but the recasting operation of'the machine'willbe inter- F rupted by the setting of the arm 29 in in. 105

operative position, the machine being, then restored to the normal condition so that it will operate in the usual .way to make a single cast from each matrix line.

to and equippedwith recasting control means as hereinbefore described, the matrices and mechanism of the machine is automatically clear, is effected by the setting of the arm 29 Q in operative or inoperative position; When said arm is set in operative position the line spacers are assembled in aline lathe 'assem- .bling"elevator which is thenraised tobring the line into position for delivery by theline delivery slide to the first elevator following which the line delivery slide returns to its normal right hand position whereit is held until released by lifting of the-assembling 120 elevatorinthe usual manner, and that the nextfollowing matrix line is not sent into the s first elevator until the recasting of the preceding line has been completed, any suitable Imeans being employedonthe machinefor preventing the sending of anotherline into the vfirst elevatorwhile r'ecasting of the pre ceding line is taking place.- For example, as shown in the present instance, a lever 58 may be pivoted at 54 to the transfer channel 1 operating'a r state d above.

the upperarm of this lever having a finger lever normally overlying the asscmblying elevator 1 while in its normal lowered position to prevent lifting thereof, and a pin 57 is secured to the line delivery carriage 10 in a position to engage the lower arm of the lever 53 when the line delivery carriage returns to its normal line receiving position, the pin 57 acting to swingthe lower arm 56 of the lever 53 into position above the assembling eleva- 1 tor. In operation, when thefirst elevator approaches its uppermost or line removing position following completion of the last recasting operation, thefull ascent ofthe first eleva tor being then permitted by the lever 27 which finger on the upper arm ofthe lever 53 will be swung upwardly by the first elevator,

will then be swung clear-of the stop 49, the

thereby swinging the lower arm of the lever 53 from above the assembling elevator so that the latter may be lifted to'introduce another matrix line into the line delivery'carriage 10 for transfer to the first elevator, and upon the return of the line delivery carriage to normal position after introducing the line into the first elevator, the pin 57 will engage the lower arm 56' of thelever 53 and swing its lower end into positionabove the assembling elevator and thereby prevent lifting of another line into the line delivery carriage. relation with the assembling elevator while the desired number of casts are being made from the preceding matrix line, since the lever 27 will be in a position to prevent ascent of the first elevator to its uppermost point where it engages the finger'55 on the lever 53 until the last recast has been made whereupon it is moved into normal or'ina'ctive position in the manner hereinbefore described, it then permitting full ascent of the first elevator and movement of thelever 53into posi-' tion to release the assembling elevator, as
