71 Claims.

This invention relates to slug casting machines, such as Linotype machines of the general organization represented in U. S. Letters Patent to 0. Mergenthaler, No. 436,532, wherein circulating 5 matrices and expansible spacebands are composed in line by the manipulation of a keyboard, the composed line transferred to a slotted mold for the casting of a type bar or slug, and the matrices and spacebands thereafter separated and returned by a distributing mechanism to the magazines from which they started.

More particularly, it relates to lmachines equipped to handle not only lines of full length as ordinarily, but in addition lines of less `than full length' (regardless of their actual length). lUnder certain conditions, the two line clamping jaws are movable equi-distantly toward each other until arrested by contact with the opposite ends ofA the composed line for "centerin'g;'

whereas under other conditions, one jaw or the other is movable independently into contact with 'the line, for. quadding at the rightor at the left, as the case may be. Heretofcre,A the operation of the machine for centering, quadding left or-quadding right, has been determined by conditioning mechanism settable manually in one of three positionsdepending upon the condition desired, or to a fourth position if the machine is to operate normally o1'. without quadding orcentering. When the latter condition exists, the machine is free to function in the usual way, the right hand jaw being left normally stationary and the left hand jaw being adjustable by the customary devices. g Y

According to the instant invention, it is proposed to operate the conditioning mechanism automatically during a machine cycle of operation, and to control the operation of such mech- Vanism by keys arranged adjacent the keyboard 4'0 within convenient reach of the operator or by a perforated tape through mechanism similar to that used in the so-called Teletypesetter machine. More specically, the conditioning of the two line clamping jaws (which are operated through i5Y two distinct trains of connections from a vertically movable rod actuated directly from the main shaft of the machine) is effected by a grooved collar mounted. for rotation only at the upper end of the vertically movable rod, the collar `50 Ybeing rotatable from neutral positionthrough a quarter turn in one direction to engagefa pin associated with one train of connections (e. g., the

one for operating the right hand jaw) to condi.

tion the machine for quadding at the right, and

55 also rotatable from neutral position through a quarter turn in the opposite direction to engage pins associated with both trains of connections to condition the machine for centering.

When the collar is in its neutral position, ordinarily it stands clear of both pins so that neither 5 train of connections is rendered operative, the machine, under such circumstances being free to operate in the usual way.

In the present instance, however, the neutral position of the collar is utilized for left hand quad- 10 ding, the pin associated with the train of 'connections for operating the left hand jaw being made movable to engage the collar and thus bring the left hand jaw under the control of the vertically movable rod. 1 15 The rotation of the grooved collar is brought about by a pair of toothed rack bars slidably mounted on the vise frame and connected to the grooved collar through suitable gearing, the arrangement being such that when one of the rack 20 bars is moved downwardlythe grooved collar is rotated in one direction to effect the conditioning of the mechanism for quadding right, whereas when the other rack bar is moved downwardly, said collar is rotated in the opposite direction t0 25 eect the conditioning of the mechanism for centering". 'I'he return movement of the rack `gars restores the grooved collar to neutral posiion.'

'I'he movement of the pin to condition the ma- 30 chine for quadding left is brought about by a U-shaped lever, pivotally secured in the vise frame, and swingable in a. horizontal plane in one direction to eiect engagement of the pin with the collar and in the opposite direction to eiect disengagement of the pin therefrom.

The setting of the rack bars and of the U- shaped lever as well as their restoration to normal position are brought about by the line transporter or first elevator, which is equipped with 40 actuating devices (one for each rack bar and for the U-shaped lever) selectively rendered active bymechanism controlled by the operator at the keyboard or by the tapeoperated mechanism referred to, above.

These' and other features of the invention will be fully set forth in the detailed description to follow.

^ and N2 protruding The matrices X and the expansible spacebands Y (see Figs. 1, 8, and 9) are' composed in line in the assembler A under .the restraining inuence of a line resistant which can bel set for lines of different length, all in the' usual way. After the line has been composed, the assembler is raised to position the line between the fingers of the line delivery carriage B, which thereupon moves tothe left (and in doing so inaugurates the operation of the machine) and transfers the composed line through an intermediate channel B1 into the vertically movable transporter or first elevator C slidably mounted in the vise frame D. Upon receiving the line, the rst elevator immediately descends to positionit between the left hand jaw E and the right hand jaw F and in front of the slotted mold G, which latter then advances from the rear and into contact with the line and the two clamping jaws for the slug casting operation, the line, prior to casting, being allned and justied in the-usual way when the machine 4is bef ing operated under the usual conditions. After the slug has been cast, the mold is carried from its horizontal casting position (as shown in Fig. 1) to a vertical ejecting position by a. three-quarter rotation of the mold disc G1, the first elevator in the meantime being raised to deliver the composed line to the matrix and spaceband distributing devices and finally coming to rest in its original or,

nected at its upper end to the respective jaws through the medium of two similar or oppositely disposed bell crank levers E2 and F2 pivoted at E3 and F3 to the vise frame D, the longer arms of said levers being connected by short links E4 and F4 to jaw supports E1 and F1 respectively, and the shorter arms of said levers being arranged for connection to the rod H. According to this arrangement, when the rod H is moved downwardlyrom its uppermost position (which is the normal position of rest), it will move the two jaws E, F equidistantly toward each other (assuming both to be connected to the rod) until they contact with the opposite ends ofV a composed line which has previously been positioned between them, and when the rod is moved upwardly to its position of rest, it will in like manner move the jaws equi-distantly away from each other to return them to their original positions of maximum separation. Since the composed lines positioned between the jaws may vary in length, the actual extent of movement of the rod H will of course vary accordingly.

In providing for the connection and disconnection of the rod H with and from the jaws E and F, the rod (see Fig. 10) is provided at 'its upper end with a grooved collar N formed for engagement with diametrically opposed pins N1 inwardly from the extremities of the horizontal arms of the actuating levers E2 and F2 for the jaws E and F, respectively. WhileA the particular construction and operation of the collar N forms partof the present invention, suce it to say at the moment there are four conditions provided for; the iirst or normal condition wherein neither of the :laws E and F is connected with the rod H and thus will remain in their fully separated positions to accommodate lines of normal or full length; a second condition wherein the right hand jaw F is connected to the rod H for quadding right; a third condition wherein the left hand jaw E is connected to the rod H for quadding left, and

a fourth condition wherein both jaws are connected to the rod H for centering.

The rod H is slidable in suitable bearings H2 and H3 of the x'ed vise frame D, being provided about midway of itsA length with a collar H1 carrying an adjusting screw (not shown) which banks against the underside `of the bearing Hi1 when the rod is in its uppermost .or normal position of rest. 'Ihe extent to which the rod H will descend during a quadding or centering operation will depend` solely upon the length of the line between the line clampingjaws and, when the rod in its descent is arrested by the contact of the line clamping jaws with the ends of the line, it is locked in its arrested position.

In order to lock the rod H in its downwardly moved position, there is provided a toggle member J (see Fig. 4) enclosed within a box or housing D1 which carries the bearing H3 before alluded to. This toggle member J operates a clamp or grip element J1 arranged to contact with a sleeve T carried by the rod H. For the purpose of the present description it is unnecessary to go into the details of construction and operation of the actuating mechanisms for the rod H and toggle lock J, except to say that both are controlled and actuated in proper time sequence from a cam mounted on the main drive shaft of the machine.

Were the rod H and its sleeve T actually joined together as one, it is plain that there could be no spread of the composed line after the sleeve is locked in position by the toggle member J and, in such circumstances, the jaws would be locked directly in their line contacting positions which actually happens when the lines are composed without spacebands. However, the arrangement is such that the jaws may be moved outwardly from their line contacting positions to a limited extent after the locking of the sleeve T in order that a composed line may be spread to a. corresponding extent under the expanding influence ofthe spacebands Y, provision being made usually for allowing the line to spread up to three ems in extent. This is accomplished by providing for a. relative movement between the rod H and the sleeve T after the latter has been locked by the toggle member J in the downwardly moved or line clamping position.

Referring particularly to Fig. 4, it will be noted that at its lower end the rod H is provided with a fixed collar T1 which contains an expansion spring T2 encircling the rod H and pressing upwardly on the lower end of the sleeve T. 'I'his lifting tendency of the springv T2, however, in the downwardly moved position of the rod H is resisted and overcome by one or another of a pair of rotary camsV or V1 carried by a sleeve V2 rotatably mounted on a stud xed to a bracket T3 carried at the upper end of the sleeve T and arranged to engage a roller h carried by a collar H1 pinned to the rod H and, when either of the cams in its operative position is set with its high point in contact with the roller h, it will by reacting thereagainst and over the oppo- Vsition of the spring T2, hold the sleeve T in con- 1 'tact' with the xed collar T1 at the lower end of the rod. Under such setting of the cams as will now be evident, there can be no relative movement between the rod H and the sleeve T and the two parts function as if they were rigidly united, which is the condition that would exist when casting from lines without spacebands. On the other hand, when' either of the cams is set, say to bring its lowest point in contact with 'the roller h, then the sleeve T in the downwardly moved position of the rod H will be raised by the spring 'I2 out of engagement with the collar to permit the maximum spread of a composedr line during justification, which ordinarily is,`

three ems. When it is desired to provide for a less spread of a composed line, the cam V.

or V1 in use is set in an intermediate position, that is to say in a position intermediate its lowest and highest points.

The upward movement of the rod H to spread the jaws for expansion of the line is effected by mechanism not herein shown, but which is operated by a cam arranged on the main drive shaft of the machine and acting through suitable mechanism `to actuate the rod H. The c'am just referred to comes into operation after the sleeve T has been locked in its downward position by the toggle member J and acts to move the rod H upwardly with reference to the sleeve T until the rod collar. T1 banks against the 'lower end of the sleeve, the extent of such relative movement of the rod being, as previously stated, determined by the setting of the cams V or V1, whichever happens to be in operative position. It is this upward limited movement of the ro`d H which moves the. line clamping jaws outwardly from their line contacting position and thus determines the iinal q-uadding or centering position of the jaws when a composed line is to be spread or justied by the expansion of the contained spacebands.

If it is borne in mind, now, that ,the extent of line spread during justification should be uniform irrespective of Whether the line is to be presented to the mold at the centering or at either of the quadding positions, the reason for the two cams V and V1 is at once apparent. If but one cam were used and such cam were Set to produce, say a one em spread of the jaws if the rod H were connected to but oneA jaw, as in quadding right or left, the same setting of the cam would result in twice such amount of spread if the rod were connected to both of the line clamping jaws, as in centering, since any movement of the rod H is reected in a corresponding movement of any jaw which happens to be connected to the rod H at the time.

In order therefore to insure the same spread of the jaws during both centering and quadding for a line of a given measure, the two cams V and V1 have been provided, mounted for rotation about thesame axis but diiering in eccentricity, the one of greater eccentriclty being brought into register with the roller h for centering, and the one of lesser eccentricity into register with said roller during quadding, either left vor right. The adjustment, of the cams in one position or another is eiected automatically during the'conditioning of the machine for the performance of the centering and quadding functions and `will be described hereinafter.

It-should be noted Ithat if the jaws E and F are set for a maximum spread of say three ems of spread for a line of say half measure. Under normal conditlonsthe average number of spacehereinafter pointed out, is the saine as set forth in the patents to Frolander No. 1,971,400 and Morrison et al. No. 1,971,424, to which reference may be'had for any further details.

The fore-and-aft movement of.' the pin N1 is brought about through the operation of a U- shaped lever M (see Fig. 20) pivotally mounted near its center on a bracket M1 screwed to the vise frame and arranged to be swung through a limited distance in a horizontal plane under the control of mechanism on the iirst elevator which is set to operate the U-shaped lever automatically when the machine is conditioned for quadding left. This mechanism will be described in detail later. The U-shaped lever at its inner end is formed with an arcuate portion M2 (see Fig. 2) having a .groove m in its outer edge adapted to receive a iianged head N3 formed at the outer end of the pin N1. The arrangement bf the parts is such that when the Ushaped lever is in its outermost position, the pin N1 likewise will be in its outermost or normal position, where it will clear the collar N; whereas, when the lever M is in its innermost position, the pin N1 likewise will be in its innermostposition where it will engage in the groove n formed in the collar N, despite the fact the latter isv still in its neutral position, as previously described. Under such conditions, the left hand line clamping jaw E will be connected through the collar N to the vertically movable rod H and, as the latter descends,'the left hand jaw will be moved toward the right hand jaw until arrested by the composed line for quadding left. Furthermore, the connection between the U-shaped lever M and pin N1 remains unbroken throughout the quadding operation, for, as the rod H descends to eiect the inward movement of the jaw and then moves to its uppermost position to restore the parts to normal (carrying with it, as it does, the collar N) the head of the pin N1 merely tracks along inthe groove m formed in the arcuate portion M2 of the U-shaped lever (which remains in its innermost position), the shape of the arcuate portionl conforming oi' course to the path the pin N1 will followas the lever E2 turns upon its pivot. After the rod H reaches its uppermost position, the lever M is swung outwardly to dis engage the pin N1 from the collar N.

At this point, it may be stated that the collar N is heldin any of its adjusted positions by a spring detent n2 adapted to engage in any one of three depressions n3 formed in the rod H (see Fig. 12).

The collar N is turned from normal to one or another of' its adjusted positions for quadding right and for centering) by one or another of a pair of long rack bars O and. O1 arranged for limited up and down movement at the back of the rst elevator C and in front of the vise frame D. The rack bars are guided in their up and down movement, at their upper ends, by a recessed plate 03' screwed to the vise frame and, at their lower ends, in recesses formed in the rst elevator at the rear thereof (see Figs. 2, 4, and 20) The rack bars adjacent their upper ends are equippedwith teeth O3, O4 meshing at diametrically opposed points with a pinion O5' fixed to the front end of a hub O1 rotatably mounted on a lmeshiirig at the bottom with a third pinion 010,.

which latter is fixed at the front end of a shaft O11 frotatablymounted in the bracket O8 and provided at its rear end .with a small bevelledl gear O12 adapted to mesh with a corresponding bevelled gear N4 secured to the upper face of the collar N. 'I'he arrangement is such that as the right hand rack bar O is moved downwardly under the iniiuence of the vflrst elevator, as will be later described, the collar N, through the train of gears just mentioned, is rotated through a one-quarter turn in a counterclockwise direction to the position shown in Fig. 14, wherein the pin N2 engages said collar to connect the vertically movable rod H'with the right hand jaw for quadding right; whereas, when the left hand rack bar O1 is moved downwardly to rotate the pinion O5, the collar N is turned a quarter of a turn in the opposite or clockwise direction, thus bringing it in the-position shown'in Fig. 15, wherein both the pins N1 and N1'engage the collar to connect both line clamping jaws with the vertical movable rod H for centering.A

It will likewise be noted that during this latter operation, that is, when the mechanism is conditioned for centering, the cam V1 (which normally is in register with the roller h and which determines the extent of spread of the line clamping jaws during either of the quadding operations) is moved to the right and the ca m V (which controls the extent of jaw spread during centering) is brought into register with the roller h. This operation .is brought about automatically by the movement of a slide O13 (Fig. 2) arranged for horizontal travel in the bracket O8 and, which,

upon being shifted to the left, operates, through V11 formed on the sleeve, the length of the lower portion V10 of the lever being sucient to accommodate the full travel of the sleeve as it is moved downwardly with the sleeve T during quadding or centering. Furthermore, when the lever Va moves to bring the cam V into action,

such movement is against the tension of a spring'` V12 anchored to the vise frame and which serves to restore the parts when the slide O13 is again returned to normal position. The normal position of the lever V9 and consequently the parts f aiected thereby is determined by a pin O15 xed in the bracket Oa adjacentA the lower edge thereof and against which such lever at its upper end abuts.

The slidel C)a is moved from normal position to the left as just described 'as the pinion O9 (which meshes with an overlying toothed rack bar 01 fixed to the slide) is rotated by the left hand vrack bar 01 in conditioning the grooved collar N to eiect the connection of the rod H with both line clamping jaws for centering, and is restored .to normal position when the rack bar 01 is moved upwardly after the'casting operation.

The operation of the rack bars O, O1 and the iJ-shaped lever` M to eect the connection of the vertically movable rod H with the line clamping jaws E and F for the various conditions mentioned is ,broughtabout bymechanism carried by the rst elevator and which is rendered operative' immediately after the rst elevator starts -to descend from its line'receivlng position. This :mechanism includes a pair of relatively short levers P' and P1 pivotally mounted adjacent their centers on the rst elevator at a position sometocontrol the operation of the U-shaped lever M which functions in the setting of4v the devices for quadding left. Normally the levers P, P1, and P2 are held under the control of a series of three trip dogs p, p1, and p2, one foreach of said levers, pivotally mounted on a fore-and-aft rock shaft in a box P3 screwed to the rst elevator in a position just beneath the lower ends of the levers just referred to, said trip dogs being held in spaced relation by intermediate partitions p2.

The trip dogs (see Fig. 17) are formed with upstanding ngers p5 which, in the normal. position of the parts, stand in front vof the levers P, P1, and P2 at the lower ends thereof, the nger p5 on the outer trip dog p2 being arranged to cooperate with the long lever P2 active in quadding left, that Aon the inner trip dog p1, with the short left hand lever P1 active in centering, and that on the inner trip dog p with the short right hand lever P active in quadding right.

'I'he trip dogs are arranged to beselectively operated in the manner later to be describedsaccording as the machine is conditioned for a quadding right, a quaddi-ng left, or a centering operation and, as the trip dogs are operated v(immediately after the first elevator starts lto descend), the lower portions of their respective levers-P,` P1, and P2 will be allowed to swing forwardly to retain the trip dogs in their tripped position. l

y To be more specic, let it be assumed that it is desired to condition the machine for a centering operation which will involve the selection of the center trip dogzo1 for-operation. As\the rst elevator starts to descend, said trip dog will be moved to a position (see Fig. 17) wherein the ar-.

resting finger p5 thereon will free the short left hand lever P2 and allow the lower end thereof to be drawn forwardly under the action of a tension spring p2 securedto said lever and anchored at its front end to the wall member of the box P3 until it banks against the partition p3 immediately adjacent the front face of the trip dog p1 (see Fig. 5), it being understood that the rear wall of the box P3 and the partition at the rear of the trip dog p1' are formed with notches to In this position of the lever P1, a'shoe p10 (Fig. 5) screwed .to the upper end thereof will overlie a shoulder o first elevator continues in its descent, said rack bar will be drawn downwardly and through the train of gears between it and the grooved collar N, rotate the latter through a quarter of a turn to condition the machine for centering in. the manner previously described. As the first elevator continues to descend, and after the down-` ward movement'of the rack bar Ol has progressed sufficiently` far to set the collar N, the .lever P1 is disengaged from the rackl bar by the action of a plate o1 (Fig. 6) screwed to the vise frame in back of the rst elevator and which is provided at itsupper edge with a bevelled surface o2 'that reacts againsta dog P4 adjustably secured to the leverlPl just `above its pivot point to cam said lever back toV normal position where it is brought under the' control of the trip dog p1 erated to free the right hand lever P which will operate in exactly the same way as the left hand lever to draw the right hand rack bar 0 downwardly to condition the parts forv quadding right. After the slug has been cast and the line clamping jaws restored to normalv position by the upward movement of the rod H, the collar N is returned to normal position to effect ythe disconnection of the line clamping jaws, such action being brought about when the rack bar Oor Ol (whichever has been operated) is restored to normal position. The restoration of the rack bars is eifected by the upward movement of the first elevator which,for thispurpose is provided at its lower end with a bail member C1 (Figs. 2 and 3) pivotally mounted on a pair of brackets c screwed to the first elevator. The bail member is formed with a pair of shoes c1, one for each of the rack bars, and in the normal position of the bail memreaches itsA normal position, the ball member (ll is rocked rearwardly against the tension of a spring c2 anchored to the left hand bracket c to permit the elevator to ascend to its upper line transfer position, this rocking action being brought about by the engagement of an offset arm portion c2, formed at the left end of the bail member, with a banking stud d fixed to an arm d1 depending from a bracket on the vise frame and positioned in the path of travel of said oiset arm portion c2.

In the operation of the machine for quadding left, it will be recalled that the collar N remains in its neutral position and that the connection of the vertically movable rod H to the left hand jaw Vlever is effected by the fore-and-aft movement p5 of whichV engages said lever at its lower end.

When the operator sets the machine for quadding left, the outermost trip dog p2, as the first elevator starts to descend, will be turned to free the lever P2 and the upper end thereof is immediately swung rearwardly under the influence of a pull spring p11 to actuate the U-shaped lever M, a

shoe m1 fixed at the extremity of the front arm of the lever Mat this moment being directly behind and in the path of acorresponding shoe p12 secured to the upper end of the lever P2 (see Fig. 10). A stop screw p13 protruding from the front face of the elevator limits the active stroke of the lever P2 and thus saves undue wear and tear on the parts associated with the U-shaped lever M. The-pin Nl controlled by the lever M is thus projected into the groove n of the collar N and the machine is conditioned for quadding left. In the normal or inactive position of the lever P2 (Fig. 4), as will be.u1nderstood, the shoe p12 is ladapted to pass the shoe m1 without disturbing position through the upward movement of the vertically movable rod H, the lever P2 is restored to normal position during the ascent of the rst elevator to its upper line transfer position. 'I'he devices for this purpose include (Fig. 11) a bevelled surface 4o3 formed at the lower edge of .the rack retaining plate O2 and which rea/cts against a roller p14 carried by the lever P2 near its upper end to ca m the lever back to normal position under the control of its associated trip dog p2 as the latter springs back into normal position. Immediately after the lever P2 has been restored to normal position, the U-shaped lever M is rotated in a clockwise direction to withdraw the pin N1 out of the groove n in the collar N to disconnect the left hand jaw from the vertically movable rod H. This movement of the lever M is effected by the bracket Psy which supports the lever P2 on the rst elevator and which is formed at its outer end with a bevelled surface arranged to engage a complementary bevelled surface provided at the lower edge of the dog m1 and cam the lever M to normal position as the rst elevator continues to ascend (see Figs. 10 and 11).

The trip dogs p, p1, p2 are selectively operated according as the machine is conditioned for a quadding right, centering, or' a quadding left operation by a set of three horizontal slides Q, (one for each trip dog) positioned at the right of the first elevator and just beneath the trip dogs when the rst elevator is in its normal or line receiving position. The slides Q are arranged to be selectively projected into the path of iingers p4 formed on the corresponding trip dogs prior to the descent of the rst-elevator to casting position so that as the elevator starts to descend, the active slide will trip its corresponding vtrip dog and release the conditioning actuating lti `mechanism controlled thereby.

Immediately after the trip dog has been operated, the active slide is returned to normal position and it or either of the other slides may be 'set again. immediately for controlling the conditioning of the next line even prior to the ascent of the rst elevator to line transfer position for reasons and' each of Vtheslides) abut when the slides are in their rightmost position, wherein they are normally held by tension springs Q5 secured to said lugs and anchored to studs q projecting from the bottom ,of the frame. The slides themselves are held in the frame by pin and' slot connections of' which in addition limit the-movement of the slides toward the left. The slides are equipped each with a pivoted dog Q against which the trip dogs p, DI and p2 react, the dogs Q6 being held against turning in one direction under the inu.- ence of the trip members by pins qa projecting from the slides and against which the dogs rest in their normal positions.y 'The dogs, however, are

permitted toturnin the opposite direction against the tension of springs 119 connect/ed to lugs formed on the lower portions of the-dogs and anchored -to the slides, this pivoting of the dogs being pro- 'vided in the event 'that a slide Qset for one line has `been restored 'and the same .or another slide set forth the next line while the elevator is still in its lower or line casting position.

As a further precaution against breakage of the parts, means are provided for permitting only one of the slides Q to be operated at a time. These safety means include (Figs. 17 and 18) a setof three pawls 'q1, q11 and qm plvoted on pins 113 extending between the side walls of the frame Q4 and spring pressed to engage in combination notches q14 formed in the upper edges of the slides. The arrangement of the combination notches q14 is illustrated in Fig. 18. As shown, the pawl qw at the left will cooperate with two short notches in the two innermost slides and one long notch in the outermost slide, the center pawl ql1 will cooperate with short notches in the outer and inner slides and a long notch in the center slide, while the third pawl q12 (not shown in this view but shown in Fig. 17) will cooperate with two short notches in the two outer slides and a long notch in the inner slide. The relative positions of the notches are such that in the normal position of the parts, each pawl is immediately above two short notches but just to the left of the long notch in its associated combination where it rests against the upper edge of the slide having the long notch. Now it--is evident that if Y any slide isl actuated to the left, the long notch therein is brought in register with the pawl associated with that particular combination, whereupon said pawl will drop into all of the notches of such combination, thus eiectively preventing themovement of the two slides formed with the short notches, but

' permitting the continued movement of the-actuat the ends of the dogs engage behind upstanding lugs q1'I formed on the upper edges of said slides.

Immediately after a trip member p, pl or p2 (which selectively release the conditioning devices on the first elevator) has been operated and upon the continued descent of the rst elevator, the latch dog Q1 associated with the active slide is rocked by one of a set of three pawls p15,

' slides Q are active for a brief period only, so that a slide may beset for conditioning the machine for a second line long prior to' the time the casty ing of the rst line has been completed.

The pawls p16 are pivotally mounted on a common shaft pi@ extending between the front and rear walls of the bracket l?3 (in 'which the trip members p, p1 and p2 are carried) and are held by torsion springs p17 against a stop p4, the arrangement being such that as the rstA elevator descends, not only will the dog Q1 associated with the active slide be rocked, but also the other two in addition so as to permit the free passage of the pawls without interference, whereas upon :the upward movement of the rst elevator, said pawls p15 will themselves be rocked against the tension of the springs p11 by the dogs Q1 to permit passage of the pawls when the iirst elevator is moving upwardly. It might be here stated also that the nose portions of the dogs Q6 on the slides Q are offset (see Fig. 19) so as not to interfere with the passage of the pawls p15 during the descent and ascent of the rst elevator.

'I'he slides Q are actuated to the left by a set of three levers` S (Figs. 17 and 21) pivotally mounted adjacent their centers in a frame S1 secured to the-main frame of the machine. Each of the levers near its upper end is in register with one of the slides Q and is guided in its pivotal movement by partitions formed in the upper portion of the frame S1. 'I'he levers at their lower ends are formed with nose portions s1 which in the normal position of the parts bank against nose portions s2 formed at the ends of three\ corresponding lateral arms of `a set of three bail members S2 pivotally mounted on a shaft S3 supported at its opposite ends in bearings carried by` bracket means Vsecured to the main frame (see also Figs. 1, 7, 8, and 9). Each oi these bail members S2 is selectively operated by one of three keys positioned adjacent the keyboard of the machine (one key for quadding left, one key for centering and one key for quadding right, as indicated by the letters L, C and R in Fig. 7) and,- when a selected bail member S2 is operated, the nose portion s1*A thereof is raised to permit the nose portion s1 of the corresponding lever S to move beneath it into a bail notch s3 provided for the purpose, such movement of the lever being effected by a spring S4 connected thereto and anchored to a stud proiecting from the lever supporting frame S1. However, the actuating lever S, which has been conditioned for operation by the bail member S1 selected, does not actuate its associated slide Q immediately, for the levers are held against operation at this -time by a pin s4 provided at the lower end of a long offset lever S5. This lever S5 is pivotally mounted adjacent its center on a bracket S8 screwed to the main frame and is provided at its upperend with a roller S5 riding in a cam groove aformed in a member A1 screwed to the assembler A near its lower end (see Figs.v1, 8, and 9). -The nose portion s1 of the lever S selected for operation does, however (see Fig. 21) enter for a short distance beneath the nose s2 of thev corresponding bail member so that said lever will be in condition for operating the slide Q associated therewith when releasedl by the pin s4, this action being due to the fact that certain clearance is provided between the pin s4 and the vturn'in a clockwise direction, underthe influence o'f a torsion spring s6 arranged at its pivot point, to free the lever S that has been conditioned for operation by the bail member S2 which previously was selectively operated from the keyboard. Immediately upon the release of a lever S, the slide Q corresponding thereto will .be actuated to the left to position its associated dog t.)6 beneath the particular trip member p, p* corresponding to the key selected.

As the assembler A continues to ascend to the line transfer position (see Fig. 9), the roller s5 rides out of the depression a2, camming the lever ,S5 in a counterclockwise direction to restore the p1 or operating levers S and the pin s". This operation is effected by a slightly raised surface a3 immediately beneath the depression a2 in the cam groove, and when the levers S have been fully restored, the bail member s2 (whichever onehas been actuated) will be permitted to return to its normal position to retain its associated lever S l in place.

As previously stated, the bail members S2 are controlled from al set of three iinger keys (one for quadding left marked L, one for centering marked C, and one for quadding. right marked R) and which are formed respectively at the ends of three horizontally arranged parallel key levers W pivoted adjacent their centers in a frame W1 screwed to the keyboard frame at the right (see Figs. 7, 22, and 23). The key levers W are connected to the bail members through a linkage arrangement including a set of three verticallymovable rods W1' mounted in a guide frame W3 screwed to the keyboard supporting bracket and connected, at their upper ends each to one of the key levers through an voiset plate W4 notched at its end to receive a nose portion w formed at the end of each of said levers, and at their lower ends, each to one of a set ofthree rocker arms W5 through a pinand slot connection w1. The rocker arms are pivotally mounted at their centers beneath the guide frame W3 and are connected respectively to the bail members S2 through links W which are pivotally fastened at their upper ends to the rocker arms W5 at the ends thereof opposite those at which the rods W2 are connected, and at their lower 'ends to said bail members. The arrangement is such that as a key is depressed, its associated rod will be moved upwardly against the' tension of a spring w, one being provided for each rod, fastened to the rod and anchored to the guide frame W1 to swing the associated rocker arm and depress the corresponding link W8 which in turn rocks the bail member to release the proper slide controlling lever S. When the lever S which has been actuated is returned to normal position up'on the full previously described, the active bail member together with the corresponding key lever and intermediate linkage are restored to normal position by the tension springs w2 referred to before.

It may of course be desired to maintain the setting of the machine for a given condition during the casting of a plurality of`successive lines and for this purpose there are provided a set of locking levers W", one for each key. pivotally mounted in the key lever frame just above the key levers and forward of the pivot points thereof. When the levers W'1 are in the position shown in solid `ascent of the assembler elevator.v in the manner lines in Fig. 22, such levers will be functionally inoperative, but when they are swung rearwardly to the position shown in dotted lines, the lower ends thereof will engage their respective key levers, thereby retaining the keys in a depressed conditionfthus maintaining the nose of the bail member corresponding to the depressed key in a vposition always to release its associated slide operating lever S. It might be stated here, however, that the slide operating levers S do not reline transier position, these levers are restored to nonnal position by the lever S5, but under the conditions stated the lever S corresponding to the key locked down, will constantly maintain its engagement with the control pin s* so that when the assembler elevator is again lowered to the line assembly position, said slide operating lever will again enter slightly beneath the nose of its associated ybail member, with the result that the same lever is in condition again to operate when the assembler is raised to transfer the next line.

Of course, it is quite essential that one key only be operated at a time; for, if more than one were operated, it would result in a condition where more than one of the slides Q would be actuated were it not for the presence of the locking pawls q11 which, under such circumstances, would prevent the actuation of any of the slides-and thus give rise tothe result that a short line wgzuild be presented to the mold under normal conditions of operation of the machine; and no-casting operation would result. The operation of more than one key at a time is prevented by a pair of weighted dogs W8 (Fig. 23B) pivotally mounted on a cross plate W9 fastened to the key lever frame e and beneath the key levers, the arrangement being such that if one key is operated, the dogs will assume a position beneath the other two keys,

thus effectively preventing their operation. Thus. if the center key is operated, the dogs W will be n separated to assume a position one under the left hand key and the other under the right hand key, whereas, if the key at the left is operated, both dogs will be displaced to the right to assume a position, one under the center key and one under the right hand key; and should the right hand key be operated, the dogs will be actuated to the left, assuming a position, one under the center key and the other under the left hand key.

As stated at the outset, the machine may also be set automatically by mechanism operated from l a perforated tape. The mechanism for this purpose is shown' in Figs. 7 and 24 to 26, and may include a set of three solenoids W10 mounted on a bracket W54 secured to the machine frame and having their respective armatures W11 connected to a different one of the bail members through bell crank lever W12 pivotally mounted on the bail supporting shaft S3, so that by selectively energizing the solenoids to draw in their armatures. one or another of the bail members will be swung to release the corresponding slide actuating lever S in the same manner as this is done when the machine is operated by the nger keys.

The solenoids'areconnected in parallel to a source of electrical energy W13 through a set of three rectangular and pivotally mounted switches W14 which are provided at one end with bars W15 adapted to enter notches W16 formed in the usual code bars W1".

' In the normal position of the-'code bars (setting I, Fig. 25), the bars W15 with which the switches are equipped will be held against the lower edges thereof by tension springs W18, but

when the code bars are set to bring a lnotch in each one thereof in register with one of the bars W15,

' such bar will under the iniiuence of its spring W18,

enter the row of aligned notches, with the result that the associated switch is caused to rock upon its pivot and close the circuit through the correspending solenoid, thereby conditioning the machine for centering, quadding right, or quadding left, depending upon the setting of the code bars. When the code bars are returned to normal posibe restored by the same mechanism provided forl the purpose when the-machine is operated with the finger keys, but after, of course, the corresponding slide operating lever S has been actuated and again restored to bail releasing position, which occurs as previously stated when the assembler is raised to line transfer position.

The code bars are six in number and are moved selectively to the left or right from normal position, depending upon the active combination of perforations in a tape W19, such as is used with the teletypesetting machine for composing lines automatically. A typical tape is shown in Fig. 26, and is divided up horizontally into seven sections or rows, one for each of the code bars and a center section forfeeding perforations to move the tape along. The tape is further divided up vertically into sections or rows. and each vertical row includes a combination oi perforations, representing different matrices or spacebands which will be released from the magazines, or functions which the machine will perform. 'Ihus in the example illustrated in Fig. 26, the rst combination oi perforations will,-upon the setting of the code bars in accordance therewith, condition the machine for centering the line subsequently composed, which in this instance comprises the words The Teletype with a spaceband in between the words.

The setting of the code bars W17 in accordance with the tape combinations is effected by mechanism which includes a set of six pivotally mounted bell crank levers W20, one for each codebar, provided each with a horizontal arm w3 formed at its Vwith two spaced legs 105 and 105 which serve as fulcrums for one,of a set of underlying rocker varms W25, likewise six in number, pivotally carried at their centers on a yoke W21 mounted on a rock shaft W22, said rocker arms being formed each at its opposite ends with raised portions' w" and wa corresponding respectively with the legs w5 and m5 although spaced somewhat further apart.

The arrangement is such that if no tapeper foration vregisters with a pin w* of a bell crank lever W50, such lever will assume a positionwherein its leg :v5 will overlie the raised portion w" at one end of the corresponding rocker arm W25; whereas if a tape perforation does register with a pin u# of a bell crank lever, such lever will assumefa position wherein its leg wli will overlie the raised portion w3 at the opposite end of the rocker arm. The result is that as the yoke W21 isA rocked in a counterclockwise direction, those rocker arms which fulcrum on the legs 105 of the bell crank levers W20 (whose pins have entered perforations) will act to move the corresponding code bars to the left, whereasthose rocker arms which fulcrum on the legs w5 of the bell crank levers (whose pins have not entered perforations) is eected by a cam w11 mounted on a rotatable A .'shaft w12 and which imparts its action to the yoke through an arm w13 provided thereon and
