'PATENT ore-ice .SLUGoAs'riNGMACHINE l Frank o. Frblander, Elizabeth, N. J., assigaor in Mergentlialer Linotype Company, a corporation of New York Application December ,21, 1932, Serial No. 648,199

" `39 Claims. (Cl. 199-47) This invention relates to slug casting machines, such as linotype machines of the general organisation represented in United States Letters Patent No. 436,532 to O. Mergenthaler, wherein circulating` matrices are released from a magazine in the or-der in which their characters are to appear in print, and then composed in line together with spacers, the composed line transferred to the face of a mold, Athe mold nlled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices and spacers thereafter returned through distributing mechanism to the magazines whence they started. More particularly, it relates to certain improvements which adapt these machines, when so desired, to cast successively and automatically a plurality of duplicate slugs from each composed line.

In the preferred embodiment illustrated (although `it is not essential), the improvements have been worked out in the nature of an attachment which can be applied tok almost any of the commercial machines with little or no alteration. Specically, the equipment consists of an adjustable control member adapted to be actuatedperiodically from the main drive shaft of the machine, andwhich is connected by means of a lever to a 'slide mounted on the vise frame, the slide being adapted when moved to one position, first, to render a stop active which limits the upward movement of the nrst elevator or line transporter to prevent the removal of the composed line therefrom until the last duplicate slug has been cast from the line; secondly, to pull forward the control rod, which, through the usual intermediate connections, trips the clutch control dog to inaugurate a machine v cycle of operation; thirdly, through other intermediate connections, to lock the assembler in normal position during the cast-- ing of duplicate slugs,so as to prevent the delivery to the 'first elevator of a second composed line until the iirst line has been removed thereon; and lastly, to eliect the operation of `a gate which y clauses theslugs to be delivered into one compartment or another of an improved `galleywhich holds the duplicate slugs in separate columns. When" the slideis returned to normal position upon a further actuationoi the adjustable controll member, the line transporter is permitted to ascend to its uppermost position after the casting of the` slug, whereupon the line is transferred to the second elevatorfor distribution to the magazines in the customary manner, the clutch control dog `again rendered operative to stopthe machine at the completion of the machine cycle of operationin which the last duplicate slug is cast, and the assembler released to permit the next composed line to be delivered to the first elevator or line transporter, whereupon the operations of casting duplicate slugs are repeated.

The exact construction and mode of operation of vthe parts will be best understood from the detailed description to follow:

' In the accompanying drawings, the invention is shown merely by way of example and in preferred form, but obviously many variations and modiiications may be made therein which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not limited to any specific form or embodiment, except insofar as such limitations are specied in the appended claims.

Referring to the drawings: v

Figs. 12, 13 and 14 are rear views of a part of the machine, showing the clutch control dog in various positions of operations.

Referring to l, when the machine is employed in the customary manner, that is to say, to produce a single slug from each composed line, the matrices are released from their storage magazine (not shown) and the spacers from their storage magazine A by a keyboard mechanism (not shown), and are delivered to and composed in line in the assembler B. The assembler B is then Imanually elevated to raise the composed line between the ngers c and c of the line delivery slide C, which thereupon transfers the line from the assembler through the intermediate channel D to theline transporter or iirst elevator E. The rst elevator E then descends to carry the line to the casting mechanism Where it is justified and then presented to the face of va mold unit into which molten metal is injected to cast a slug against the justified line, after which the slug is trimmed and delivered to the galley R. The rst elevator E ascends to its uppermost position and the line is shifted therefrom by the slide G into the upper transfer channel G', from which the spacers are returned to their magazine A and the matrices raised by the second elevator (not shown) and delivered to the distributing mechanism (not shown), whereby they are restored to their proper channels in the magazine whence they started.

As is well understood in the art, the various parts referred to, with the exception of the assembler B, which is under manual control, are operated from the main drive shaft M or the machine which is caused to make one complete rotation for each cycle of operation. The shaft M is driven by an electric motor through a spring actuated clutch (Figs. 1l to 14), this clutch being thrown into action by a trip dog J carried by a cam J' which is fast to the main shaft. When the parts are at rest, the dog J engages and depresses a stop lever J2, which, when depressed, acts through the usual connections to disengage the clutch. When, however, the dog front o f the machine, and which comprises in part a vertical sleeve J3 mounted to turn upon a xed rod J4, and which provided near Vits upper end with a radially extending arm J 5 arranged in position to engage the trip dog. This train of connections also includes a radially extending arm J6 provided near the lower end of the sleeve J3, and which extends into the path of an upwardly extending pin J'l located on a rod J8 leading to the front of the machine, Where it is connected to the control lever y' by a toggle joint consisting of a link y" and a rearwardly extending arm :i2 of the control lever y'. By this arrangement, when the control lever 7' is swung forwardly, the sleeve J3 is manually rotated, and the arm J5 caused to move the trip dog J clear of the stop lever J2, so that the clutch may be engaged in lthe manner above stated.y The details of the clutch control mechanism are fully shown and described in the Rogers Patent No. 651,386, and being so well known, they do not require any further description here.

To complete the identication of the known Vparts which function in the operation of the re- The parts so far described and their normal mode of operation in casting single slugs, in themselves constitute no part of the present invention, and are or may be of any suitable construction, such for instance as discussed in the previously mentioned Letters Patent No. 436,532, or as presented in the commercial linotype machine.

As already stated, the improved equipment is intended to adapt the machine automatically to cast duplicate slugs from each of the composed lines as desired. To this end, there are employed means which may be called into action when desired for actuation by a rotating element of the machine, such as the driving gear M', and which may be adjusted so that the first elevator E is prevented from ascending to its uppermost position, thereby preventing the transfer of the composed lne therefrom, the assembler B locked against movement in normal position to prevent the delivery of a new line to the rst elevator, and the clutch control dog J rendered inoperative so as to prevent the machine from stopping at the end of a completed cycle of operation, thereby permitting a composed line to be returned to the castingmechanism a plurality of times, as determined by the adjustment of the control mechanism F.

All of the mechanisms necessary for the control of the elements involved in the casting of duplicate slugs are, in accordance with the invention, actuated from a single slide member S mounted in a channel bracket S bolted on the vise frame 'f V, and which is capable of lateral movement thereof for a limited distance, as determined by the brackets S2 and S3 mounted respectively at the ends of the slide S, the slide being arrested in its rightmost position when the bracket S2 abuts il e against the inner end of the notch S4 in the front plate Ss of the channel bracket, and in its leftmost position, when the bracket S3 abuts against the inner end of the notch S5 in the opposite end of said front plate.

When the slide S is in its rightmost position, theelements necessary for arresting the rst eievator E in a position preventing transfer of the line therefrom, for locking the assembler B to vprevent delivery of a second line to the rst elevator, and for rendering the clutch control dog J inoperative, are active, so that the line may again be returned to the casting mechanism during subsequent machine cycles of 'operation for casting duplicate slugs; whereas when the slide S is o manner in which these elements are operated by the slide S will be described hereinafter.

" The periodically adjustable control member F is arranged to provide a large variety of adjust ments, whereby the number of duplicateslugs-cast from a composed line may be varied as desired, the adjustable member, F being such thatihe slide S on the vise frame Vis maintained in its active or operative position for a predetermined number of machine cycles `ci operation, as` determined by the adjustment. The adjustable member F effects its control of the slide Sthrough a lever L pivoted substantially at its mid-point to a bracket L mount-eden the machine frame, the lever being connected at its front end (Fig. 7) to the slide S by means of a detachable connection consisting of a retractable L2 which normally projects upwardly between the bifurcated arms S7 of a connecting member S8 extending through a slot provided in the rear portion of the channel bracket S', and which is suitably connected to the slide S as by a screw S9 (see Fig. 7). The arms Srl slope upwardly and are divergent, 'as shown, in order to insure that the connecting pin L2 will enter properly between the arms when the vise frame is returned to normal position after having previously been lowered. The connecting pin L2 is held in normal position by a spring L3, but may be retracted from between the arms S7,

.l against the tension of the spring when it is desired to use the machine without the recastlng mechanism, a knob L4 being provided at the lower end of the pin to facilitate its retraction. To hold the pin L2 in retracted position, another pin L5 1s l provided, projecting from the pin L2, and which is adapted to abut against the under surface of the end of lever L, when the pin L2 is withdrawn and 4rotated slightly.

The control member F (Figs. .2 and 4') is carried by a rear extension of the bracket L and is provided with a plurality of cam members F (twelve in the particular embodiment shown),

.which may be adjusted into and out of alinernent with the rear end of the lever L. Underlying the plate F2 which carries the` cam members F is a ratchet wheel F3 adapted to be engaged by a stud M2 carried by the drive gear M, the arrangement being such that uponeach complete rotation of the drive gear M', the control member F will be rotated through a distance equal to the `pitch between two cam members. When the control member is rotated to bring an alined cam F in operative relation with the end of the lever L, said lever will be actuated in a countercloclrwise direction against the pull of a spring L6 anchored to the supporting bracket L, as shown in Fig. 2, to actuate the slide S on the vise frame V to the right, in which position, as hereinbefore stated,l

the control elements operatedby the slide are `rendered active to effect the recasting operations.

thisfcycle of operation isv such that the cam F' "opposite the lever L willl be `-out of alinernent therewith. Furthermore, it will be obvious that any desired plurality of duplicate slugs may be recast simply by adjusting-aproper number of cams F in position to aline with the lever L. Thus, if it is desired to cast three duplicate slugs from one line, the control element/F is adjusted so that every thirdrcam F is out of alinernent with the lever, and the intervening cams in alinement therewith. To castlfourduplicate slugs, every fourth cam Vis out of alinement with the lever,

and for six duplicate slugs, every sixth cam, and V so forth, so that with a comparatively few con-y trol elements practically any desired number of duplicate slugs may be cast automatically from a line. Y

As avmeasure of safety, the rear end of the lever L is provided with a dog L7, pivoted to the lever, and having an adjustable set screw L2 adapted to abut against an opstanding lug L9 on the lever, the screw being normally held against the stop by a compression spring L10 which is stronger than the spring L6 for returning the lever L and slide S to normal position Under normal conditions of operation, the dog L' and lever L func tion as a unit, but in the event of an interference preventing the actuation of the lever L or slide S, the dog Lr1 will yield against the tension of the spring L10, permitting the alined cams F to ride past the dog without harmful results.

The construction. of the adjustable control element F is shown in detail in Fig. 9. The unit is detachably mounted by means of a bolt F4 on the rear extension of the supporting bracket L', and as mentioned before, consists of a ratchet wheel F3 to which the cam carrying plate F2 is pinned for integral rotation therewith. The cams F are each pivoted on a stud F5 projecting upwardly from the plate F2, and into a hollow cylindrical grip member F6 Vformed as an integral part of the cam, a spring F7 being provided between the head of the stud F5 and the base of said member, which tends to urge the cam F toward the carrying plate. Each cam has a depending pin F8 adapted to be received either in a shallow recess Fg for holding the cam in the nonalining position or in a hole F10 extending through the plate F2 for allowing the cam to come in contact with the plate in the alining or operative position. As will be observed, a r cess and a hole are provided for each cam element. i

As previously mentioned, the slide S mounted on the vise frame V is adapted to actuate different sets of control elements when the recasting mechanism is operated, rst, means for limiting the upward movement of the `first elevator E to prevent the transfer of the line therefrom; secondly, means for rendering the clutch control dog J inoperative; thirdly, means for locking the assembier B in normal position to prevent transfer of the second line to the iirst elevatorA E, and lastly, the gate R (Fig. 6) which determines the compartment of the galley into `which the slug is to be delivered.

In order to limit the upward movement of the first elevator E or line transporter, there is provided a stop V' pivoted to the vise frame V and adjacent the first elevator E (Figs. l, 6, 'I and 8).

In the` normal operation of the machine, that is, when a single slug is cast from each line, the stop V is inactive, but when it is desired to cast duplicate slugs, the stop is rotated to bring one arm V2 thereof in alinement with a projecting lug E located on the lower end of the'r'st elevator slide E. Thus, when the `stop is in active position, the first elevator E will be prevented from ascending to its uppermost position and will be brought to rest in the position shown in solid lines in Fig. 10, wherein transfer of the line is prevented. When the rst elevator E is in this position, Vtransfer of the line is prevented by means of a pin E2, carried by an arm E3, mounted at the left end of the line supporting member, the pin in this position resting in front of a projecting lug G2 on the end of the transfer slide G, which of course prevents the usual movement of the transfer slide to the right to eifect transfer of the line. When the stop V1 is inactive, the elevator will ascend toits normal line transfer position, as shown by the dotted lines inFig. 10,*in which position the stop pin E2 will come to rest above the level of the projecting lug G2, thus permitting the operation of the slide G in the usual manner to transfer the line.

The stop V1 which limits the upward movement of the elevator E is actuated. by the slide S, by means of a pin S10, adjustably held in the bracket S2, and the lower end of which extends into a notch V3 provided in a member V1 pivoted to a radially extending arm V5 of the stop V1, when said member is turned up in its active position, as shown in Figs. 6 and 7. Thus, when the slide S is moved to the right by the adjustable control member F at the rear of the machine in the manner heretofore described, the stop V1 is caused to rotate in a counterclockwise direction, bringing its operative end into alinement with the lug E on the rst elevator E to limit the upward movement thereof. When the slide S is moved to the left, the stop V1 is rotated to inactive position, permitting the full ascent of the first elevator E, and the transfer of the line therefrom in the customary manner.

When it is not desired to use the automatically recasting mechanism, the stop V1 may be disconnected from the pin S10 merely by swinging the notched connecting member V1 down into a horizontal position, as shown in Fig. 8, so that the stop may be manually operated, if desired, in the usual manner. In order properly to position the rst elevator to prevent transfer of the line when the automatic recasting mechanism is employed, a set screw E1 is provided in the lug E on the lower end of the first elevator slide E which is adjustable to raise or lower the elevator in well known manner.

The clutch control dog J is rendered inoperative during the recasting cycles by a 'train of connections also actuated by the slide S and which eifects the control of the dog J through the usual manual connections provided for this purpose. Referring to Figs. 2 and 3, theusual bracket which carries the manual control lever j is replaced by a bracket J9, having a forward extension, adjacent the outer end of which is 'pivoted a plate J10. When the recasting mechanism is brought into action and the slide S moved to the right, this plate is swung in a counterclookwise direction to actuate the rod J8 forwardly through the medium of a tension spring J11 attached to said rod. When this occurs, the sleeve J2 of the clutch control mechanism is rotated (as is usual when the machine is started by the manual lever 7'), and the-arm J 5 caused to move the trip dog J clear of the stop lever J2, the clutch remaining engaged continuously as long as the slide S on the Vvise frame V remains in the rie'htmost position, or during a plurality of cycles of operation, as determined by the adjustment of the recasting control element F.

Asshown inFigs. 1, 2, 3 and 6, the rotation carrying the manual control lever y'.

of the plate J10 is effected from the slide S through a dog' S11 carried by the bracket S3 at the right end of the slide, This dog has a bevelled end S12 which contacts with a downwardly extending pin J 12 on the plate J10 to swing the latter in a counterclockwise direction to render the clutch control dog J inoperative. When the slide S is returned to normal position, during the casting of the last duplicate slug, the plate 510 is llikewise returned Ato normal position, as determined by an upstanding pin J13, on the plate, abutting against the edge of the support bracket J2, this movement of the plate being caused by the tensionV of the spring J11. The normal position of the plate and the associated operative parts is shown in Fig. 2. The dog S11 is held in its normal operative position by a depending pin S13 resting against the supporting bracket S3, where it is maintained by a spring S1l1 pulling on the pin. if, for any reason, it is desired to lower the vise frame V on its pivots,

the bevelled end S12 of the dog S11 will clear the depending pin J12 on the pivoted plate J10. Should it happen, however, that the slide is inadvertently moved to the right when the vise frame is in its lower position, the dog may be obstructed by the depending pin J12 when the vise is raised to normal position, but no harmful eiect will result, since the dog will merely swing on its pivot against the tension of the spring S14 which holds it in place. In order to reset the mechanism, under such circumstances, it is only necessary to turn the plate J1 in a 'counterclockwise direction by hand, permitting Ithe dog S11 to snap back into place, after which the plate is released.

As stated before, it is desirable to prevent the delivery of a second composed line to the first elevator during the casting of duplicate slugs. In accordance with this invention, this is accomplished by locking the assembler B in normal position during those cycles of operation in which duplicate slugs are cast, means also being provided for releasing the assembler after the last duplicate slug has been cast, to permit a new line to be delivered to the elevator E. For this purpose, a dog K is adapted to be swung into and out of vertical alinement with a projecting lug B' on the assembler B. Thus, when the dog K is brought into active position overlying the lug B', which operation is brought about by the movement of the slide S on the vise frame to the rightmost position, upward movement of the assembler is prevented; whereas, when the dog is moved to inactive position, out of alinement with said lug, the assembler may be operated in the usual manner to deliver a line which has been composed therein to the first elevator E. As shown in Fig. l, the dog K is mounted on the upper end of a rod K carried by a bracket J13, formed as an integral part of the bracket J9 At its lower end, the rod has a radially extending arm K2 'carrying an adjustable screw K3 at its outer end, adapted to abut against the edge of the rearwardly extending arm i2 of the manual control lever y'. When the rod J2 is pulled forwardly by the operation of the slide S on the vise frame to accomplish the setting of the elements for the recasting operations, the manual lever j, through its link connection i1 with the rod J3, is likewise caused to swing forwardly, the arm i2 of the lever j, engaging the arm K2 to swing the dog K into active position in alinement with the lug B on the assembler B. The dog K will recate slugs.

main in active position as long as the slide S 'remains in the rightmost position, and thus will prevent the operator from sending a. new line 'to the first elevator during the casting of dupli- When the slide S is again moved to the leftmost position during the cycle of operation in which the last duplicate slug is cast, the 'rod J8 is actuated rearwardly in the usual manner by the clutch dog controlling mechanism, to return the manual control lever 7 to normal position. The operationV of the lever 7' in this manner, permits the dog K to be moved out of alinement with the lug B' on the assembler B by a spring K4 pullingv on the arm K2 and anchored toy the bracket J9. i

If, for any reason, the spring K4 does not withdraw the dog to inactive position, such action is positively effected by means of an upstanding arm K5 connected at the front end of the space band lever rock shaft G3, this arm having a spring retained dog K6 at its upper end adapted to coact with a pin VK7 extending radially from the vertical shaft K', which carries the assembler lock dog K. With this arrangement, when the space band lever is swung to the left during the Operation of the transfer slide G after casting the last duplicate slug, the spring retained dog K6 will contact with the pin K7, and positively push the assembler lock dog out of' vertical alinement with `the lug B' on the assembler B. In the event of an interference preventing the release of the assembler lock dog K, the dog K6 will yield against thev tension of its retaining spring, thus preventing breakage or other harmful results to the various parts.

The improved galley R is provided with a plurality of compartments for holding the slugs in separate columns in order that duplicate slugs may be kept apart, and thus obviate the necessity of sorting them out by hand later on. In the present embodiment, referring particularly to Figs. 1 and 6, the inclined galley R is divided into upper and lower compartments R2 and R3, respectively, into which the slugs are selectively delivered as they are ejected from the mold, and in which they are progressively advanced by a stacking device (not shown). rllhe means for determining the column into which the slugs are to be stacked, comprises a movable gate R positioned in line with the discharge end of the chute (not shown), into which the slugs are ejected from the mold. When the gate R is in the lower position, as shown in Fig. 6, the ejected slug will, of course, be stacked in the upper compartment R2, whereas when the vgate `is swung upwardly, the ejected slug is stacked in the lower galley. b

The gate R' israised and lowered by the opera- .tion of the slide S on the vise frame, the means for this purpose comprising an arm R4 pivoted to the slide channel bracket S', and which carries the gate R' at its outermost end. When the slide S is in the leftmost position, as shown in Fig. 6, the gate K is in its lowermost position, and the slugs are delivered, as mentioned before, in `the upper galley R2. When, however, the slide S is moved to the rightmost position, the pivoted arm R4 is raised by means of an upstanding pin S15 xedly secured in the slide` S and projectingl upwardly through a slot S1G in the slide channel bracket S', the upper end of this pin eoacting with a downwardly sloping plate R5 attached to and extending to the right of the pivoted arm R4, so that when the slide is moved to the right, the pin pushes the arm to the, upper position,

raising the gate and permitting the slug to be delivered to the lower'galley R3. Upon the return of the slide S to the leftmost position at the beginning of the cycle, during which the last duplicate slug is cast, the gate is lowered by gravity in position to retain said slug in the upper galley. This arrangement is particularly applicable in case where one duplicate slug only is cast, for, in such instances, the slide S is move.' to the right during the casting of the first slug, and to the left during the casting of the second'slug, the duplicate slugs thus being delivered into separate columns in the galley, which, of course, will obviate the necessity of sorting them out later on.

In the operation of the machine, when it is desired to cast duplicate slugs, the recasting control device is nrst adjusted to cast the desired number of slugs, that is, if one duplicate slug is to"be cast, alternate cam elements F' are adjusted into position to aline with the lever L,

for two duplicate slugs (three similar slugs) two adjacent cam elements are adjusted in alinement and the third out of alinement, and so on. As the normal position of the machine is one wherein the first elevator E may ascend to its uppermost position for transferring a line, and wherein the vclutch control dog J is operative and the assembler lock K inoperative, the slide S on the vise frame V will rest in the leftmost position. Such being the case, the rear end of the slide actuatingrlever L will be positioned opposite a cani element F out of alinement therewith. TheV first composed line is then delivered to the first elevator E and the machine started in the usual manner. At the beginning of the cycle vof operation, and before the elevator E starts on its upward movement toward the line transfer position, the actuating stud M2 on the ,drive gears M', rotates the control mechanism F to bring the next cam F' opposite the end of the lever L, and as this element is in Valinement with the lever, the latter is rocked as heretofore described to move the slide S to the right, in which position, the first elevator stop V1, the trip J5 rendering the stop dog inoperative, and

theV assembler lock Klare brought into action.

At the same time, the gate R associated with the galley R is raised. The line is justified in lthe usual manner, and the slug cast and deafter, the recasting control member l5A is advanced one step, bringing an unalined cam element F' opposite the lever L, which, of course, permits the return of the lever and the slide S connected thereto to the normal or leftmost position under the pull of the spring L6. The return of the slide S renders the first elevator stop dog V2 and the assembler lock K inactive, restores the clutch control mechanism to position to stop the machine at the end of the cycle, and lowers the galley gate R. This cycle will, therefore, be the usual normal one of the machine, that is to say, the line of matrices will be transferred from the first elevator for distribution, the machine stopped at the termination of the cycle, and the assembler released for transferring a second `line to `the elevator. `As the gate R' is in its lowermost position, the slug cast during this cycle will be delivered vinto site the end of the lever L.

The invention may readily be attached to machinesalready in the eld, since it involves no substantial changes thereto, the installation being made simply by the attachment of the bracket L to the main frame, the slide channel bracket S to the vise frame, and a new bracket J9 substituted for the one usually employed for supporting the hand control lever.

In the accompanying drawings the invention 'has been shown merely in preferred form and by way of example, and obviously many variations and modifications may be made therein without departing from the spirit of the invention. It is to be understood, therefore, that the invention is not to be limited, except insofar as such limitations are specified in the appended claims.

Having thus described my invention, what I claim is:
