Application filed June 25, 1906. Serial No. 323,222.

To all whom it may concern:

Be it known that I,'Ooniin V. SioURnssoN, a subject of the King of Denmark, residing York, State of New certain Improvements in Type Castino and Composing Machines, o'f which the fdllowing is a specification.

Ihe ob] ect' of this' invention is the production of amachine capable of casting type at the maximum speed at which they can be automatically' assembled in words and lines and set up" in agalley. To Vthis end a plurality of similar sets of matrices and their attendant operating mechanisms, each -constituting a type font castin unit, are combined with and controlled y a single keyboard and, by vtheir driving devices, are caused to move through regular sequences of operation, simultaneously casting type in successive stages of the cycle through which each of the sets of type producing devices and mechanisms passes, the type being successively delivered as fast as they can be automatically .set up. This,

devised by me, adapted to produce the results contemplated by this invention are shown in the accompanying drawings, in which;

Figure 1 is chine showing the general arrangement of the various operating devices, with the frame partly broken away; Fig. 2, a plan view of the saine, with the up )er plate of the machine removed, on the iine 2, 2, Fig. 1; Fig. 3, a rear elevation, with some of the bracket supports of the frame broken away to ex pose the working arts behind them; Fi 4, a side elevation o the matrix bars and t cir operating and controlling mechanisms, on an enlarged scale; Fig. 5, a. rear elevation of a portion of one of the. matrix .bars and its t pe niold,'with parts in section cut on the line 5, 5, Fig. 6; Fig. 6, an end sectional view of the Same take-ii on the line 6, 6, Fig. 5; Fi 7, a plan view of Fig. 5, taken on the line 7; Fig. S represents portions of Fig. 7 with the type mold open; Fig. 9, a front view of one of the drivin wheels and its electrically controlled cliitc Fig. 10, a plan side elevation of Fig. 10, taken 'on the line 11, 11; Fig. 12 shows-:some of the key levers, their relation .to and connections with the electric controlling city of New York, have inventedl with other t novel features of construction of a machine,

The drawings illustrate three substantially '"--i similar type makin .devices or units assembled in'a suitable i board or set of keys a by the manipulation., of which the'type making units may .be set in action .and controlled, and the three umts may, underl ordinary workingl of the machine, be in action at the same time, each being controlled` by' a se arate key, orby successive manipula-tion o one ltr-when any ty e character is to be `repen i No attempt is imade to show connections between the driving wheelspf the various parts of the machine, itl bein understood of course that they will be positively driven to rame .and a. single keyinsure .harmonious operation of the various parts and devices. The driving wheels b, c and (l of' the three t pc forming units continuously rotate free y on three short shafts e, f and g', arranged in alinement in suitable bearings. The driving wheel L actuates the mechanism for making the space pieces, and the driving wheel z' secured to a short shaft j causes the resetting of the matrix bars of all of the type casting units after they have performed' their functions in the formation of the type. Both of these wheels are continuously driven.

The wheel la is shown as the actuating means of a device indicated by Lm, a for setting the type 0,-as made, in lines and setting .the lines of type-in the galley p. As this part of the machine may be able construction as for instance that disclosed in the U. S. Letters Patent No.` 528,857, dated November (i, l18%, or others known to thisart, it is not fully illustrated and will only be casually referred to here-` after.

To afford quick action and reduce the work of the operator in manipulating the character keys, electrical devices are utilized to cause the'driving Wheels I), c and CZ to engage their respective shafts. The connecftions are shown in the diagram, Fig. 12, in which y represents a source of electricity, as

- a battery, one terminal being in communication with all of the key levers and the other with the electro magnets 7j', s and t located respectively near the driving Wheels b, c and (I. The return wires of said magnets end in the insulated plugs u, o and w carried by a sliding frame 2, (Figs. 1 and 13), which is moved and controlled by cams y and z, (Figs. 2 and 3) carried by the shafts e, f and g respectively,4 as hereinafter described. Ihe electric circuit is completed by a spring contact piece 1, insulated from the metal parts of the machine and, arranged to bear against any one of the. plugs u, 'u or fw acording to the position of the frame 2, and any one of the key levers 3.xvhose inner end contacts, when the key lever is depressed, withy avplate 4, preferably spring acting, electrically connected tothe spring contactpiece 1. This plato 4. extends across the machine and is in the paths 'of motion of the ends of lill of the levers 3 of the finger pieces a of the bank of cl'iaracter keys.

The three drivingr wheels c and d are provided with .similar clutch mechanism; .being clearly shown at Figs. Adjacent the wheel and secured to the .shaft .is the .clutch controlling cam 5 between which and 'the wheei is ioeagted-:a lever' actuated friction clutchI 6 o f ondinary. construction, the horizontally arranged operating-leyer 7' of which is pivoted atriue-end tothe post 8, and provided at the 9th ndsvtlra 'pivoted latch 9 having a' of any suiti .'chine.

tracts the armature 13, pivoted in bearings on the bed of the machine and havingr an upwardly extending arm 14, with a pin or lug at its upper end fitted to slide in a groove 15 formed in the underside of the latch 9. This arm 14 also has a bracket extension 16 the end of which is in the path of a ledge 17 on the side of the cam 5 inside its active surface. This cam is broken away in Fig. 11, and shows only the active parts, and in the three views the ledge 17 rests on the top of the bracket 16 thereby holding the shaft e in normal inoperative position. Upon energization of magnet r arm 14 is moved outwardly, bracket 16 is moved away from ledge 17 and the lug 10 oflatch 9 is caused to pass beyond the periphery of the cam 5, permitting the spring 12 to operate the clutch 6 and connect the driving wheel to the shaft e. One revolution of the sha'ft causes a complete opera-tion of all the part-s of the type casting unit actuated by it, and just before the termination of a revolution, the magnet r. having been denergized by opening of itsv circuit at plate t (Fig. 13) on release of the key lever, the latch 9 is by its spring broughtinto active position to cause the release ofclutch 6, and the bracket 16 being again in the path of ledge 17 arrests further movement of shaft c. There is provided a molten meta-l reservoir 18 for the three type casting units. It has discharge spouts 19 through which the molten metal is injected into the type molds, means for heating' the reservoir to keep the metal in molten Acondition, and mea-ns for injecting the metal None of these operating Y tion. ,":Each of the typ casting units is p' ovided with similar means for actuating `the meta-l injecting devices at proper time.

means comprise cams 20, 21 and 22 Such (Figs. 2 and 3) secured to the driving sl'iafts @,--j and q respectively; levers 23, 24.-

and 25 (Figs. 1, 2 and 3) located under the cams, pivoted respectively at one end to the bed of the machine and having a roller at the central art, and connected at the other end by the links 26, 27 and 28 (Figs. 8 and 4) to the levers 29,4 3 0 and 31.respectively. Each of these latter levers consists of4 two arms and a'roc'lr Figs. 2 and 3. having bearings in the, top pate of the mathe rods32, 33 and .34 which pass into metal reservoir 18 and they actuate the metal injectors of the type 'casting unit, inthe order in which the units are set in action, by the Their inner ends are connected to springs 35, 36V and 37, arranged as shownin l described but completed bythe lug o, .the

the View of the upper partV of the machine Fig. 4, to act on the rods 3,8, 39 and 40 resting on the tops of the inner ends of the 1e vers 29, and 31 and' guided by having bearings in the frame and a bearing piecel on the top of the frame. The operating parts of the cams20, 21 and 22 are depressions in theirl p eripheries which allow the springs 35, 36 and 37 to act as quickly as is necessary to cause the molten metal to How into the molds at the proper times.

The sliding frame .2 is composed of the 'side bars 2, 2, and crossppieces or rods as 2a.

- second unit, and after it has set the frame 2 This frame has the functionv of setting the electrical controlling means, is supported at the front end by a rod or roller 41 and at the rear end by two arms 42, 43 pivoted to the ends of the side bars 2, 2, and secured to and carried by a rock shaft 44, having bearings on the bed plate of the machine,

and having secured to-it the three camlevers or arms 45, 46 and 47` ofthe cams ai, y/ and a respectively. The frame 2 is heldin normal forward` position by a spring'or springs 48. Its step by step movement is accomplished as follows; Vwith theinachine at rest it occupies the position shown at F 14 and 15 and in the main views of the drawings, with the contact. plug u on the spring 1, the other i two positionsbeing. shown by -the dotted lines, Fig. 13. Then vthecircuit is closed by the endy of one` of the key levers 3 touching, the plate 4, the-emrent traverses the electro Vmagnet o of lthe first type. casting unit, thereby putting its shaft e into action, asjdescribed when referring to Figs. 9, 10

anidhill.; the canina-,acting on' the roller of the a1'm45, see Figs.. 14, and y15, sets the framel2 `into the position shown at Figs-..16 and 17 with plug fv in contactwvith spring 1; and shaft ,e after'lnaking a full revoluf,

tion during .which -the cams carried thereby have completed their functions ina cycle of IIS operations to` cause atype to'be cast by this firstunit of the machine, will be stopped as before described. The cam arm` 46 of the cam y of the second unit is pivoted by its connection `with the shaft 44 in such manner that while compelled tolrock with the shaft it is free to move towards and from theface of the cam y, being pressed toward said face by a spring 49 (Fig. 20). This construction also applies to the camarm 47 of the cam z of the third type casting unit. Fig. 20, showing one such cam arm indicates how the ends of the rollers of the two cam arms bear against the faces of the cams when the machine is in normal condition. Now in the position occupiedl by the frame 2, Figs. 16` and`17, the roller of the arm 46 is pressed into the cam recessed in the face-of y andacts as a lock to-hold the frame 2 in this set position. Upon the manipulation of a character key, the circuit is 4Iclosed as before of arm 47 from the cam and current then passes through the e cetro-mag-V net s of the second unit,and the shaft f of this unit is then caused to make a full revolution and a type is produced by its type forming means. The working part of this cam y moves the frame 2 into the third pod sition with the spring 1 bearing on the plug.

into the third position, the roller of the arm 46 is forced beyond the face of the cam by the inclined surface 50, and to hold it in this position while the third type casting unit is going through its cycle of operations, there is rprovided a latch 5l pivoted to a post 52 and held on or towards the to of the arm 4G by a spring 53.y This latc as 'shown at Fig. 17 has ja widened end and an incline joining this end to the narrowv part lwhere a pin 54 on the end of the arm 46 will slip beyond the edge of the narrow part as the arm is pushed away from the face of the cam by the incline 50, and the latch will fall down behind the pin, which will ride up to the widened end of the latch and. so prevent the roller-.of the arm 46 catching into the cam recess during the retrograde movement of the sliding frame 2 by the springs 48, after said frame has been released from the action of the .third cam z. With these parts as now arranged, Figs. 18 and 19, on closing of the circuit, by contact of a key lever 3 with plate 4, current will pass by plug fw to the electro magnet t.. and set the thirdtype casting unit into action to produce another' type from its type forming devices. During the rotation of the shaft g of this unit the incline 55 of the cam a will release the roller permit the spring 48 to set the frame 2 in its original position with the spring 1 bearing against the plug u.

-The next operationof the first described unit follows that of the third unit. By this construction and arrangement of the starting and operating gear of the type casting units the latter may be manipulated by the i character keys, besuccessively put into operation and be caused to work at the same time each producing a different type, the various operations of the units following one another in proper sequence, so that type will be produced from each of the units at regular intervals and as fastras they can beset up. The operations of the type casting units will follow in regular order, whether the'J same key, or different keys, is manipulated-'to set Ithe type casting units into action. The' type matrices of all of the type casting units are `the sliding frame 2 to winding 'adapted to form complete similar fonts,

other ends supported by springs 63, 64 andv 65 (Fig. 1), which rest o'n a bracket at the other end of the frame; this construction permits the molding faces of theA matrix bars to be pressed firmly against and raised away from the type casting molds, as hereafter described.

The matrix bars and-.their attendant devices and operating mechanism are similar in all essential features, the differences in the construction ofsome of the parts being only changes of positions or reversals of levers &c. to meet the re uirements of practical working, as one of tiem (in the special construction illustrated) is operated from the right hand side and the other two from the left hand side of the machine, so a description of one will be readily understood as applying to all. Figs. 21 and 22 illustrate themeans employed for movi the matrix bars 56, 57 and 58 along their respective guide bars, the same consisting of spring actuated drums or pulleys 66, cords or chains 67 connecting these pulleys to one of the ends of the matrix bars, cords or chains 68 extending from the other ends of the matrix bars over guide pulle s 69 and 70 and longitudinally through the lower partiof the machine a lit-tlcl above up pulleys or drums 71 fitted freely on the short shaft j, which is continually driven by the wheel z'.

The matrix bars are normally held in thepositions shown in the main vviews of the drawings by the p ivoted latches 72 engaged in notc es formed in the underside at one end of the bars, the springs of the drums 66 then being under tension. The latches 72 are released by the connected vertical rods 73, 74 and 75, of the units respectively, being pushed upwardly as hereafter described; the springs of the druius 66 then being free to draw the matrix bars along their guide bars and at the saine time move the stop slides 7 6,

77, 78 (Fig. 13), that are secured to the' cords or chains 68, along the guide Ways formed in the pla-te 79 located above the inner ends of the key levers The key levers have extei'iding upwardly fromtheir inner ends pivotetl lingers 80, that are moved into the paths of the stops 7 6, 77 and 78 to arrest the forward or setting movement of each of the matrix bars to bring into' operative relation to the mold that one of the type' matrices Athereon corresponding to the character on the finger piece a of the lever actuated. To move the matrix bars back to nor- `plislied by cams 82,

'pivoted at one en mal position after the type are formed, the drums 71 are pressed against friction disks 81, secured to the shaft y'. This is accomi 83 and 84 (Figs. 2, 21 casting units, levers 85 to a suitable part of the frame Work Aand having rollers at their outer ends and drawn against the cams by springs 86, and rods 87 connecting the levers 85 to the short arms of bell cranks 88 whose long arms are yoked and embrace grooved hubs of' the drums V71. At the right times the cams 82, 83 and 84 canse the drums71 to be` pressed against the friction disks 81,

and 22). of the ty which quickly, through the power applied to the wheel z', draw the matrix bars back into normalpositioii to be again locked by the latchesf( 2.

Between the plate 79 (which holds and guides the stop slides 76, 77 and 78) and the sliding bar 2 is a curved, plate or bridge piece 89" (Figs. 12 and 13) having a series of transverse guide slots through which extend the upper arts of the lingers 8O of the key levers 3. he lower ends of the latch rods 73', 74 and 75'of the' matrix bars also pass through one end of this bridge piece.

The fingers 80 extend through a longitudinal opening (Figs. 12, 13 16 and 17) in the sliding frame 2 and are thereby caused to move'with this frame as it is set in the different operative positions by the cams as, y, e of the type casting units, so that the upper ends of the fingers 80 will be Iocatedin the path of the stop slide 7 6', 77 or 78 of the unit brought into action. To release the corresponding matrix bar a liftin plate 90, is located beneath the rods 73 4, 75. This plate is attached to the end of a bar` 91, having end arms 91* pivoted to the sides of the sliding frame 2, Beneath this bar 91 exl tend projections 92 from the edges of the -key lever finfrers 80. When a key lever 3 is moved the elaectric circuit is closed at late y 4 as before described, the end of the ever v80 is in the path of one of `the, matrix bar stop/slides 76, 77 or 78, and the latch 72 o f the matrix bar, of the unit just started, is disengaged'from the bar by the lifting action of plate 90 on the corresponding rod 73, 74 or 75, this operation being accomplished by the projection 92 on the key 'lever finger 80 lifting the-.bar 91. The matrix of the selected character is arrested` in molding position by engagement of the stop slide '76,

77 or 78 with the key lever finger 80 tFig. 21), where it is locked and rigidly held, the mold set and the casting operation performed by'inecha'nism now to be described.

The matrix bars 56, '57 and 58 have formed in their upper surfaces alining` or locking teeth throughout their length which -are engaged by'correspondingly formed teeth 4, 21 and 25) on the lower ends of vertical bars 93, 94 and 9'5 fitted to slide in 'ted to slide on the a plate 96 attached to or forming part of the upper frame of the machine. These locking bars\are actuated by springs 97 in a downward direction to press the bars down on to the matrix' bars and to force the 'matrix faces of said bars firmly against the tops of the molds; the springs 97 being strong enough to insure a tightq'oint between the matrix bars and tops of the molds and to overcome the resilience of the springs 63, 64 and 65, which latter springs raise the guide - bars 59, 60, 61 and lift the matrix bars 56, 57 and 58 away from the molds after the types are formed therein. T woof the locking bars 93 and 95 slide 4in grooves on one side of the late 96 with their springs 97 arran ed vto orce them down, see` Fig. 4, and the ot er bar 94 with its spring is in a groove on the other side of the plate. One of the molding devices, that at the ight handside of the machine, is shown at Figs. 5, 6, 7 and 8. It isv carried on a slide 98 fitted in suitable guide ways on the `frame, and comprisestwo main parts constructed to slide relative to one another to rovide for varia tions in the size ofthe mo ding chamber for casting type of different width and for opening the mold to discharge the type when cast. The molding chamber 99 is formed iii the recessed sliding surfaces of the two parts of the-'nlold, as shown in the plan views Figs. 7 and 8. A type letter W is shown in the moldin Fig. 7. One lpar-t of the mold 100 is securely attached to the slide 98 and the other part 101 is by dovetail guides fitpart 100 and rawii towards it by the springs 102, seated iii holes .formed in the part 100, their action being to-contriict the casting chamber 99. The mold part 100 liasin its side a recess 170 in which is lit-ted to'slidelat right angles to the direction in which the part 100 is moved by the slide 98) the mold part 101, and in its end a right angle recess 171 tlie walls of which form adjacent side walls of the vertical casting chamber or mold 99, the remainin side walls-of the mold being formed by a li e recess 172 in the laterally extending portion of the mold part 101 sliding across the end face of the part 100. The con' struction is clearly shown iii Fig. 25.

In normal position the casting `chamber 99 is over a type discharge chute or passage 103, 104 or 105, there being one for each unit. The several chutes converge or merge into a single discharge 106 opening into the type assembling device'l, m before referred to. As shown in the views now under consideration the devices are inA casting position, the matrix bar 58 having been set with the matrix of the .type to be cast over the metal discharge spout 19 withv the mold chamber 99 located between them. The mold is provided at its end with a short lever 107A pivoted to a bracket extension 108. Oppoing 109a into which the end of the lever 107,"

when in one position, -is free to enter, and when in the other position it bears against the face of the extension 109 and holds the'- chamber 99 open when the mold is at rest in normal position.

Tothe lever 107 isconnected a rod 110, fitted to slide freely in a bearing iii the lug 111 extending from a suitable part of the frame, and having two stop collars 112 and 113. As the mold is pushed into operative position the collar 112 strikes the lug 111 and pushes the end of the lever 107 over the hole in the extension109, thus allowing the springs 102 to act to close or form the casting chamber 99 by moving up the mold part 101. ,This movement of the part 101 is controlled by a projection 114, extending upwardly from the part 101, and by short pins 115 on the side of the matrix bar 58, in line with the matrices on the underside of the bar, the lengths of the pins being such as to accord with the proper width,.runningwise of the type beingcast, Another projection 116 from the part 100 of the mold behindl type, and the mold is moved back, as hereinafter described, to bring the Vmold chamber`-`r 99 over the type chute. 105, the rod 110 being arrested byV contact 'of its collar 113 with t-he lug 111, which causes the end of'the lever 107 toride up the rounded or inclined. edge of the hole in the extension 109 on to the facer of the extension, and so open the mold to its full extent and permit the type that has beenl cast to drop into chute-105. During the passage of the mold to this dischar e position it passes over the knife 117 whicli' cleans ofi they bottom of the type to make them all of uniformheight or length.'

The meansfor moving the type molds consists of cams 118, 119 and 120 on the shafts e, f, g respectively of the operating units: vertical rock shafts 121, 122 and 123 each having an arm 124 provided with a cam roller on its end; and arms 12". 126. 127

' 57 ;y and the arm 127 of thefthird vunit con- 50 which, at suitable regular intervals, forms nects by link 129 the sliding block 98 of the matrix bar 58. The connecting links of the arms 125, 126 and 127 also operate the locking bars 93, 94 and 95l of the matrix bars, and the one which controls the mold shown in the views just referred to is, with the mechanism of the casting devices, illustrated pe'rspectively at Fig. 25. This link 129 1s shaped to extend over the top of the sliding block 98 and engages a pin 130 thereon by a slotted opening 1in its end to provide for a certain amount of lost motion between them. From the end of this link extends a branch 131 having its end beveled or rounded as shown, and on this branch rests a rod 132 fitted at its lower end in a bracket of the frame and having pivoted to its upper end an arm 133 secured to the end of a rock shaft 134 fitted in suitable bearings and having atl its other end another arm 135 the outer'end of which engages a pin 136 projecting from the locking bar 95. This view, Fig. 25,`shows these parts in normal inoperative position, the pm 130 being at the end of the slot of the link 129 by which the type mold is moved away from the lmatrlx. When the lever 129 is started to bring the mold into operation the lost motion of the slot of the link is iirst taken up and then the mold is ushed under the matrix and over the meta discharge spout, and by the time it arrives in this position the end of the rod 132 slips off the extension of the link, allowing the locking bar 95, when forced down by its spring, t0 lock the matrix bar 58, which by this time has arrived in operative position. After a type has been cast the .retrograde movement of the link. 129 firstA causes the rod 132 to rise up on the extension of the link, thereby lifting the4 locking bar 95 and freeing the matrix bar 58 from the mold, which is then moved back when the link has moved a dista-nce equal to the lost motion of the slot of link 129.

The space pieces forming mechanism shown detached at Figs. 23 and 24 and also as applied to the machine at Fig. 1, is adaptl ed to make and feed space pieces of the coresqA rugated compressible kind. It comprises a pa1r of eorrugating rollers 137, 138, one of the space` ieces ofthe -length-required, and

v is provide in the corrugations with cutters 139, which sever the pieces from a strip 140, as they are formed, by acting a ainst the outer parts of the corrugations of the other wheel 138. The wheels are connected to run tolgether by a pair of gear wheels 141, one of w ich is intermittently driven by the pawl 142 acting on the ratchet wheel 143, and car- Aried by an arm 144, pivoted at one end and connected to the end of a lever 145 pivoted a-t its other end to the frame and having a roller 146 arranged to bear on a cam 147 carried by a short shaft on which the driv-l ing wheel 71. is placed. This shaft also carries another cam 148 which actuates a lever 149 connected toa bar 150' attached to a space piece carrier A151. This carrier rests on a ledge or table 152 and hasa chamber into which the space pieces drop as they Vare formed and severed from the strip by the corrugated rollers 137 and 138, and the space pieces are, at the right time, moved by the carrier, through the action of the cam 148, over the chute or passage 153 down which they fall tott the discharge opening into the type'collecting and setting mechanism. The driving wheel it is connected to the shaft when a space piece is to be made by the automatic spring clutch 154, "the operating lever 155 of which, with the clutch out of action, rest-s on a ledge of the lever 156 which is drawn towards the shaft by a spring 157, this spring also serving to .hold the roller of the lever 149 against the cam eraing key or bar 160 located in or near the` bank' of operating keys. When-this spacing bar 160 is depressed, the lever 15G is moved away from the end of the clutch lever, 155 thereby permittingl the clutch, by its spring, lo connect the driving Wheel toits shaft, and this shaft during one revolution causes the devices just described to be ac-` tuated and form and deliver a space piece; but, before the completion of a revolution, the vlever 156 is brought. forward by the spring 157, the,y space bar 160 having been released, and the lever 155, striking the incline on the t op of lever 156, disengages.the clutch 154 and is stopped by the ledge of the lever 156, thereby holding the shaft and itscams stationary, the clutch beingfsecured to the shaft.

At the sidesfof the corrugated rollers 137 and 138 are Llocated trimming 4knives'for ydke 163 supported by the shafts of the roll- V ers 137 and 138 and heldagainst the outer faces thereof.

The diiierencesin the constructionof the operating parts of the molds located in the right hand part of the machine and the moldshown at Figs. 5, 6, and 8, 'due to the mold openlng device being at the other endof the The lever 156 is, by a link 158 .(Fig.

mold, (see Fig. 26) is the extension 109 is rounded at its end, instead of having an opening for the' lever 107 to pass therein, and the lever 107 acts against said rounded end of the extension to open the mold when the mold is set in position to drop the type into the discharge chute, by the inner collar iso of the sliding` rod contacting with the lug 111; and the leverY 107 is moved to shp beyond the end of the extension of the mold to permit the mold to close when the vmold is moved into operative positlon under .the matrix barby the collar 113 of the controlling lever 107 v contacting with the lug 111. l The actions of these parts are the reverse of t those previously described but all of the molds are similarly constructed and' are similarly,..operated. The ydevice for o perating the mold to open the sliding part 101 f and permit it to be closed at the right time `springs 102, thereby applying the power` i chut and so open the mold to its (shown at Fi s. 27 and *28) is in Somerespects prefera le to the corresponding device shown in the other views, and consists of a lever having ai bearing in the part 10() of the mold, one arm 164 of which is connected to and moves the sliding ,part 101 about! in line midway between lthe closing As itis desirable, that -the mold be held open until it again isvin type casting Yposimold' moves back; and the tion, an arm or bar 167 extends from the arm 165 of the lever in such mannenthagits front edge bears against Aandslidesfall'g the face of the spring latch 168 during the forward movement of the mold, and its. end slips off the fac Vofftle latch as the mold ing position thereby leaving lthe springs 102 free to 4aetvto closethe mold as before described. The end of the arm 167 pushes the latch 168 out 'of its path as the latch springs up in front of the edge ofthe bar 168 as soon as the mold is fully openedl by the 'end of the arm 165 acting Aon the stud of roller 166. Another modiiication relates to the formation of the type chamber of the mold and consists of a jog 169 in the side Walliof the' chamber on the sliding part 1011 as shown at Fig. 27, to ai'ord an increaseinl the width of the type chamber when the mold is opened and thereby leave the type clear on all sides to drop 'freely from the mold.

It is to be understood' that any suitable number of type casting unit-s may be united with and controlled by a single key board, and that -it is not desired to limit the num ber to three, although it is thoughtby using this number of units ample timewill be afforded to enable type to be properly cast, and type, as cast, will follow one another as fast as they can be assembled. It is evident that variations in the construction and arrangement of the type casting units, their comiectingy parts and means of operation may be made without departmg from the spirit of the invention.r so a strict adherence to what is shown in the drawi is not to be considered requisite in practicing this invention.
