No; 889,820. Specification of Letters Patent. Patented June 2, 1908.-

Application filed June 29, 1907. Serial No. 381,395.

To all whom it may concern:

5 letters to adapt it to different fonts. A mold Be' it known that I, ODDUR V. SIGURDS- j (suitable for use in connection with this in- SON, a subject of the King ofDenmark, residing in the borough of Brooklyn, city and State of. New York, have invented certain Improvements in Type-Casting Machines, of

which the following is a specification.

.This invention relates to typecasting niachines having a character keyboard and opcrating, on depression of a key, to present a corresponding matrix tothe mold.

The invention comprises a novel organization inwhich the matrices of a font are divided among a plurality of bars or carriers mounted upon a rotative support. If the of a complete machine as is desirable to illus- 70 requiredmatrix carr1er is not'in operative potrate the subject-matter of this invention. sition, the support IS rocked'to bring it into It has been-deemed unnecessary to illustrate actuate it to bring a desired matrix carrierinto position. If all thematrices of a font be placed in line upon a bar, the latter would necessarily be about eighteen inches long and v speed of-operation be limited .byits inertia If, however, the font be and momentum. distributed over two bars, each need bebut nine inches long; and if over three, each need be but six inches long. By dividing the font among a. plurality of carriers and-movably' mountmgthe carriers on a rocking support,

experience has shown that the speed and efficiency of this-class of'machines may be lvery materially increased. All the matrix carriers may cooperate, of course, with a single mold automatically adjustable .ru'nningwise of the type to adapt itfor type of dili'erent width.

, A further feature of the invention is the employment of a plurality of series of matrix carriers, each series carrying a different font of matrices, and all the series mounted on the rotative support. By adjustment of the support either of the series carrying a complete'font may be set in operative relation to the key controlled mechanism of the machine. 1 In all cases the automatic adjust merit of the mold runningwis'e 7 of the type .wilhprovide'for variation of width of the By dividing tive view of one of the roller clutches; 12, a frontelevation thereof; Fig. 13, an-end extends longitudinally I vention) automatically adjustable runningwise and manually adjustable for fonts of different hei hts of letters is disclosed in my application filed March 8, 1907, No; 361,416.

The supporting drum or cylinder is herein after, for convenience, in the literal descrip; tion called the dmmfl, This drum 0 has three sets of matrix bars, twoin each. set i fitted to slide in longitudinal ways formedin its inner wall. Those of the several sets are respectively marked 1) b.; c c; d (1. One of the matrix bars, sayb, is normally opposite the lowermost pointin' the circumference of the drum and 1S,'tll.6Ie-fOI'e,'1I;L 081131011130 be drawn out. to; present the se ected matrix thereof'to the mold which may belocatedat the pointniarked M in 1A ilpt. biar a. ougi t e [rum -most matrix bar 'when the drum is turne oted at one end on an axis a", and at the other end is spring supported in a vertically disposed guide piece a being thereby held normally in substantially horizontal position but capable of slight depression when the se' lectcd matrix is pressed against the face of the mold by an appropriately actuated plunger such as known in the art or such, for instance, as is disclosed in my ap lication No. 361,416, filed March 8, 1907. an the bar a is fitted to slide a frame e whose upper edge is rovided with gear teeth. Its under face ias formed in it transversely one or more grooves 6, preferably dovetailed, in which fit corresponding rojections on the lower- All the other matrix bars have correspondin projections so that d the matrix bar normally lowermost asses out of interlocking engagement with t e sliding frame e and that one of the matrix bars brought into lower most position passes into interlocking engagement with said frame.

A gear f meshes with the rack on the upper edge of'frame e and has rigid with it a bevel gear f meshing with a corresponding bevel gear f 2 fast on a ertical shaftf at the lower end of which is a bevel gear f Tl.- latter gear meshes with a bevel gear f rigid with a gear wheel f that engages a rack on the under side of a bar gthat is'adapted to slide transversely in suitable Ways in the bottom part of themachine adjacent the key board. The movement of this rack will, therefore, correspondingly effect movement of the sliding f the rack bar g'and the other to a spring bar- 'rel' g so that when the sliding matrix-drawing frame e is released as presently described, the reactionof the spring barrel will effect proper advance of the frame e with that'one of the matrix bars with which it is engaged.

A projection g on the upper face of the rack under side of a slide 9 mounted in ways above the rack bar 9. A rod 9 connects the slide with an arm h mounted lo sely upon a continuously driven shaft h and serves, as hereinafter described, to actuate the slide g to return the parts to normal position after a molding operation has been completed. Finger pieces 7' are mounted upon key levers j rocking about a common axis intermediate their ends, and having at their rear ends interlocking connection with vertically movable selector plates y' located below the rack 9. On the under side of this rack near its left hand end and adjacent its front edge is a stop pin 3' and at a suitable distance from it (in this case a distance equal to half the distance taken up by the selectors 1' is another 'second matrix bar.

stop pin 7' adjacent the rear edge. See Fig. 7 and, dotted lines, Fig. 8. When one of the keys in the first half of the keyboard, i. e. that half to the left of the broken line passing upwardly through the keyboard in Fig. 2, is depressed, the selector' i connected with that key is raised. The first result of this as is later described in detail, is to release the matrix-carrying sliding frame 0! which (through the connections described and by reason of the reaction of the springbarrel g is drawn forward carrying with it the matrix bar. This movement continues until stop pin 9' is arrested by the raised selector plate j".

In Fig. 7, the selector plate that is fifth in order (counting from the left hand end'of the series) is shown as so raised and when the movements described have been completed the stop pin 7' on the rack g will have passed into engagement with said plate thereby arresting, over the mold and in operative relation thereto, the corresponding matrix in the under face of the matrix bar that has been advanced by the sliding frame e. If the finger of the operator be raised from the depressed finger'piece, its key lever will nevertheless remain down by reason of the pressure of stop pin 9' against the selector plate. When the molding operation has been completed slide g will be moved to the left to return all parts to normal position by engagement of lug g with lug g and the selector plate will drop into normal position.

Matrices corresponding With the finger pieces in the left hand half of the keyboard are carried by that matrix bar I) that is nor-I mally in the lowermost position, and the matrices of the other bar 6 (of that series of two matrix bars) correspond with the characters of the finger pieces in the right hand side of pressed, the drum (1 will be moved to bring into the lowermost position and into interlocking engagement with the frame e, the second matrix bar I) of the series and it will be automatically advanced by the sliding frame 2 for a molding operation as above described. When a key in the second half of the keyboard is depressed, its corresponding selector plate 7' is raised and by reason of engagement with stop pin 1' on sliding rack g operates to determine the position of the rack and consequently the corresponding position of said Since the stop pin j will travel over some of the selector plates 7' helonging to the last few keys of the first half of the keyboard before it reaches the selector connected with the first key of tlvsecond half of the board, the rack will be stopped improperly by contact of stop pin 7' with any one of the selectors of the last few keys of the first half of the board should it, for any reason, be raised. To prevent this,.the last few selectors of the first half of the key board are permit the free passage of notched or cut away as atf (Fig. so as to A horizontal bar is norma ly rests upon the upper ends of the selector plates j belonging to the key levers of the first half of the kev' board and a second bar m (Figs. 8 and 9 rests upon the selectors belonging to the secgo its end a vertically disposed rod k that act's 0nd half of the key board. These bars rest I upon the tops of the selector plates in front of the rack g. Lever arms 7c are secured to the topof. the bar k and are connected at their" outer ends to a rock shaft 70 Similarly, lever arms m (one only being shown in Fig. 8) are connected with the bar m and are secured at their outer ends to a rock shaft m When one of the selectors of thefirst half of the key board is raised, the bar is will be elevated and Rigidly secured to when elevated-by the rocking of shaft k to disengage;..the,sliding frame 6 from a pawl 16 pivoted upon the bar a and normally acting to lock said. frame. If a selector plate be# longing to the second half of the keyboard is raised, similarly the shaft m will be rocked and an armm. fast thereon will raise a'rod m (Figs. 9' made) that acts to release the toothed hubor annular flange a (carried by the part a and turning with the drum (1) from pawl m to permit partial rotation of the drum to'bring into proper position the second matrix-bar of a series. The pawl'lc normally engages a tooth or notch in a rod 2 forming part of or rigidly attached-to the sliding frame a and extending through an opening in the'oylindrical part a of the bar a. When, therefore, lever arm k is raised and pawl 16 is disengaged from rod 6 the whole apparatus is released and reaction of the spring barrel 9 advances the rack bar g and, through'the gearing described, correspondingly advances the sliding frame ethat carries with it the matrix bar with which it isin engagement. This movement continues until'the stop pin 3' is arrested by the. raised selector plate when the matrix corresponding with the depressed finger piece will be arrested in operative position over the mold.

After the molding o eration, the slide 9 will effect a return of a l the parts to normal position in which bar e will be rengaged by the locking pawik When lever arm m is raised by elevation of. a selector plate annular-flange a of drum a and permits the reaction of a spring '0 (applied to rod 0) to belonging to a key in the second half'of the key board, rod 9% (Fig. 4) disengages pawl m from a tooth or notch m in thehub or rock the drum, thereby bringing the second one of the matrix bars 'of'the same font to lowermost oroperative position in whichthe' drum is arrested by arm 1" that comes against a stop o The matrix bar that was in nor-.

,malpo'sition will now-have passed out of en'- .gagement with the sliding 3, and. the second one'intoengagement with'said frame.

It is necessary thatthe pawl 76 lie-again ace tuatedto permit the transfer of the selected matrix, inthe said second bar, to the mold as already described andthis is effected by a cam projection 11 on an annular flange p turning with the drum, the cam projection, as the drum comes into adjusted position, riding over a latch in theend of a pivoted lever g, Figs. 3 and 6. I This lever is forked to embrace the rod is on which, above the forked end ofjthe lever, is a collar g. The other end of the. lever has a pivoted latch g movable in one direction only and held'in normal position by coiled spring 9 The cam" projection p in riding over the latch g rocks the lever and elevates rod kflthe latch immediately thereafter droppingintov the recess'or notch p in rear of the cam projection. The lever orfarm 1" 1s loosely mounted on a continuously driven shaft r and is connected with the drum a at an ear or lug aby the rode to an adjustable block on which rod the coiled spring 0 is attached. Integral I withthis lever or secured thereto is a wheel r having a notch or tooth Also loosely mounted on shaft 1" is a lever arm r car-'- rymg aspring pressed pawl rt, the free end of-which rests on and extends laterally be yond the periphery'of the wheel 1' so as to engage a stationary tripping cam r that withdraws'it from the notoh'r.

The lever 1" can'belocked to shaft r; by any suitable clutchdevice (a common rollerclutch being indicated) that will lock the lever arm 1 to the shaftwh'en a lever ris withdrawn from the stop r forming partof the lever arm 1". The sliding matrix-moving frame e at the end of its return movement abuts against a bar 8 sliding in a longitudinal and abutting at its outer end against one arm .8 of a bell crank lever thereby forcing the other arm 8 of the bellcrank lever toward the drum. Restin upon arm s is the free end of a connectingiar s pivoted to the lever r and having a shoulder s on, its under. sidethat is enga ed by arm s When, therefore, the bell cran lever is rocked, endwise motion is imparted tothe bar is causing lever 1" to. move, out of enga ement withstop r thereby permitting the c utch to engage the constantly rotating shaft 1* to effect a sufiieient extent of movement of arm 1" to return the drum to normal position in which it is locked by: pawl m s this movement is completed, a cam surface s on the free end of the arm .9 rides againstthe-face of a ,cam postor projection s and lifts the arm out of contact with the arm of the bell crank lever thereby "permitting spring 8 to return the lever r into'the path ofgstop 1* before the revolution of the clutch is completed thereby disengag- Iingr from it.

ment by cam r is such as to afford a proper extent of movement of drum a. Immediately before the pawl r is disengaged from the wheel, pawl m drops back of tooth m on the drum thereby holding the drum in position against reaction of spring 0. In this return movement of the drum to normal position, lever q will not be rocked about its axis because the spring pressed trigger will yield as the shoulder or cam projection passes over it. Although the clutch 1S thrown into 0 eration at each return movement of the s iding frame (when keys are operated in that section of the key board that requires shifting of the drum) there will be practically no movement-imparted tothe lever r after drum a is engaged by pawl m because pawl T has then by the action of earn 1' been disengaged frc n. toothr There is arccess or tooth m and ug a as well as a cam projection and shoulder p. for each set of matrix ars. The operation described is the same whichever set of bars is in use. To change from one set to another it is only necessary for the operator to connect the rod 0 with the proper one of the lugs a When the operations described have occurred, on depression of a key in either the first or second half of the keyboard, the parts should be returned to normal position against the reaction of the spring barrel g This may be conveniently effected by the following devices. After a molding operation has been completed, an endwise movable rod 11 is moved to the right as seen in Fig. '2. This rod may be connected with and be operated by the mold controlling lever (not shown). Slide is connected by a rod 5 with a lever arm '71.- loosely mounted upon a continuously driven shaft h. Integral with this lever arm or secured to it, is a'wheel or ircular hub it having a tooth or notch h. A lever arm 11- also hung on shaft 71/ carries a spring pressed pawl 71/5 that bears upon the face of the wheel h and extends laterally beyond the wheel so as to be tripped by a fixed cam 71 The lever h can be clutched to shaft II by any well known clutch mechanism (a common roller 'clutch being indicated) that will lock lever h to the shaft when the lever arm 11- withdrawn from the stop it. This is effected \by the endwise movement" of bar "i which, bearing on the projection h of lever arm 71 swings it out of engagementwith stop h after which the arm 2' is thrown upwardly into inoperative position, indicated in Fig. 2,

by a cam face 'i thereon acting upon a fixed cam face i and permitting reaction of spring h to return lever h" into the path of the stop 71. before the revolution of the clutch is completed to thereby disengage the lever arm h from the shaft at the end of a revolution. The limited mm einent of the lever arm 7: determined by the period of engagement of pawl with wheel h im arts a sullicient thrust to rod 9 to move s ide g to the left, as viewed in Figs. 2 and 7, and, by engagement of lu g with lug g on the rack bar to return a 1 parts to the normal position in which they are locked by pawl k engaging 10( 6 On one side of each matrix bar is a series of projections 00 and the side of the guideway inwhich the bar slides is grooved shown in Fig. 4, to receive them. These pinsor projections serve to control closure of the mold as shown in my prior application, Ser. No. 361,416: They formv no part of the present invention. Incidentally they serve to hold thebars in their guideways in the upper portion of the drum 1.

Figs. 11 to 14 show roller clutches such as may beemployed in this machine. They are well known devices. The hub r from which projects the arm 1' has within it a hub r with longitudinal recesses r in which are seated the clutch rollers r". This roller hub r is integral with a disk 1" and the continuously revolving shaft r passes loosely through it and the hub. Opposite the roller slots the inner wall of the hub 1 is formed with eccentric faces 1" equal in length to the length of the rollers. A coiled spring 7'" attached at one end to the-disk r and at the other end to the outer hub r. The part 1- is a lever arm pivoted in the hub 1- and hearing at its inner end on a shoulder 1 on the disk 1- \V hen the part r engages the lever 2", the inner end of the lever turns disk 1" until the roller hub is in such position that the rollers are opposite the eccentric faces 1- and the clutch is loose on the shaft. \Vhen, however, part I is withdrawn from the arm r reaction of spring 1" turns back the roller hub r and carries the rollersinto engagement with the adjacent faces of hub 1' which are of less radius than the faces '1'. The hub is now locked to the shaft and revolves with it. The pawl r then engages notch r in disk I, and arm rfintegral with the disk, is
