TYPOGRAPHICAL CASTING MACHINE Gustave Rapprieh, West New York, N. J-., assignor to Mergenthaler Linotype Company, a corporation of New York Application February 25, 1932, Serial No. 595,016

% Claims.

This invention relates to slug casting machines, such as linotype machines of the general organization represented in United States Letters Patent No. 436,532 to O. Mergenthaler, wherein cir- 5; :culating matrices are released from a magazine in the order 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, the mold filled with molten 10. 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 from which 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 to almost any of the commercial machines with little or no alteration. Specifically, the equipment consists of a star wheel adapted to be rotated periodically by the movement of the pump actuating lever (means being provided for connecting and disconnecting the star wheel to and from the pump lever to render the attachment operative or inoperative as desired), and two main trains of connections leading therefrom and actuated thereby, one of which trains renders the automatic clutch control dog operative and inoperative during alternate cycles of operation of the machine, and the other of which trains prevents the removal of the composed line from the first elevator until the last duplicate slug has been cast therefrom, and also prevents the delivery to the first elevator of a second composed line until the first line has been removed therefrom.

' The invention also contemplates an improved galley, which is divided into a plurality of compartments adapted to receive and hold the duplicate slugs in separate columns; and associated with the galley is a guide controlled by the first elevator vto direct the slugs into their proper compartments.

The exact construction and mode of operation of the parts will bebest 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 modifications may bemade thereinwhich will ssj-still be comprised within its spirit. :It is to bein line in the assembler B. The assembler is. then understood, therefore, that the invention is not limited to any specific form or embodiment, except insofar as such limitations are specified in the appended claims.

Referring to the drawings:

Fig. 8 is a perspective View of the improved galley and slug delivery guide.

Referring to Fig. 1, 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 manually elevated to raise the composed line between the fingers c and c of the line delivery slide C, which thereupon transfers the line from the assembler through the intermediate channel D to the line transporter or first elevator E. The first elevator E then descends to carry the line to the casting mechanism where it is justified and then presented to the face of a mold into which molten metal is injected by means of a pump plunger F to cast a slug against the justified line, after which the slug is trimmed and delivered to the galley R. The first elevator ascends to its uppermost position and the line is shifted therefrom by the slide G intothe upper transfer channel G from which the spacers are returned to their mag- 15 the main shaft.

azine A and the matrices raised by the second elevator G and delivered to the distributing mechanism, whereby they are restored to their proper channels in the magazine from which they 5 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 shaft of the machine,

which is caused to make one complete rotation lever J as is done when the line delivery slide C is released, the clutch actuating spring is allowed to engage the clutch and thus start the operation of the machine. The trip dog J is also under manual control, there being employed for this purpose, a train of connections leading to the front of the machine and which comprises in part a vertical sleeve J mounted to turn upon a fixed rod J and which is provided near its upper I end with a radially extending arm J arranged so in position to engage the trip dog. By this arrangement, when the sleeve J is manually rotated, the arm J is caused to move the trip dog J clear of the stop lever J so that the clutch may be engaged in the manner above stated. The de- -tails of the clutch control mechanism are fully shown and described in the Rogers Patent -No. 661,386, and being so well known they do not require any further description here.

To complete the identification of the known "parts, it maybe added that the main shaft is also provided with a cam F (see Fig. 5) which is shaped to control the operation of the pump plunger F during each machine cycle, this cam being arranged to act upon a pivoted lever F connected to the pump plunger, and which is connected in turn to the second longer lever F which is constantly urged downward to effect the pumping stroke by an attached spring F. In this way,

. .and as also well known; the pump plunger is given one reciprocation at each cycle of operation of the'machine, its down stroke, as effected by the spring F forcing metal into the mold for the casting of the slug, and its upward stroke, as ef- 1 ,fected by the cam F being its return or inactive stroke.

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 disclosed in the previouslymentioned Letters Patent No. 436,532, or as presented in the commercial linotype machine.

As already stated, the improved equipment is sljintended to adapt the machine automatically to cast duplicate slugs from each of the composed lines when desired, to this end, there are employed means, which may be called into action at will for actuation by the operation of the metal pump 7 0' plunger F, whereby the transfer slide G is permitted to operate only at alternate ascents of the first elevator E, the line delivery slide C is prevented from transferring a new line to the first elevator until the preceding line has been rei moved therefrom, and the clutch-control dog J is rendered inoperative so as to prevent the machine from stopping at the end of the first cycle of operation, thereby permitting the composed line to be returned a second time to the casting mechanism.

Reference will be made first to the means employed for controlling the operation of the transfer slide G. As shown in several of the figures, the transfer slide G is normally locked against operation by a latch O, which is pivoted to the machine frame as at O and which is provided with a nose or shoulder 0 arranged in engagement with a pin 0 projecting forwardly from the transfer slide. At one side of the pivot 0 the latch O is provided with a forward projecting pin 0 which is arranged in position to be engaged by the head of the first elevator E in its upward'movement. If the first elevator E makes a full ascent in rising to its line removing position, it engages the projecting pin 0 and lifts the latch 0 clear of the pin 0 so as to permit the transfer slide to remove the composed line from the first elevator, as intended. If, however, the first elevator fails to rise to its full extent, it will fail to engage the pin 0 or to lift the latch 0 clear of the pin 0 and thereby leave the transfer slide locked against way that the removal of the line is preventedand permitted at alternate operations of the machine.

The means referred to, in the embodiment herein illustrated, comprise a stop piece P attached to the lower end of the forward arm of a U-shaped bail P pivoted at P to an upstanding support P mounted on the machine frame. Consequently, when the bail P is rocked upwardly, the stop P will be located in an inactive position or out of engaging relation to the first elevator which, therefore, will be allowed to make a full ascent (see Fig. 3); whereas, when the bail P is moved downwardly, it will locate the stop piece P in its active position or in engaging relation to the first elevator E so as to arrest the latter in its upward movement and thereby prevent its complete ascent (see Fig. l). The

operating connections for the bail P will be de-- scribed at a later point.

Reference will next be made to the means provided for locking the line delivery slide C against movement. As shown in Figs. 1, 2, and 6, these means comprise essentially a long looking lever T, which is arranged in the guideway wherein the line delivery slide 0 is mounted to reciprocate. The lever T, at its extreme left,

is made fast to a shaft T journaled in a sup-* porting block T attached to the machine frame, and at its rear end the shaft T is provided with a depending twisted arm T which is connected to the pump plunger F by a system of levers later to be described. Normally, the locking lever T-will occupy its inactive position as shown in Fig. 2, where it will be seen that the free endofthe lever is held, against the pressure of aleaf 'spring'T below or out of the path of movement of the line delivery slide C, thus permitting the transfer of the composed line from the assembler, B to the first elevator E. Such is the relation of the parts when a composed line. is forwarded for the first casting operation. After this first casting operation, however, and due to the operation of the pump plunger F,- the locking lever T is moved to its active position,

as shown in Fig. 1, where it will be seen that,

thefree end of the lever isadapted to engage the block C of the line delivery carriage and thereby prevent the movement of the. carriage to the left for the transfer of a newly composed line tothe first elevator for the second slug casting operation. It is only after this second slug casting operation has been effected that the locking lever T, by the second actuation of the pump plunger F, is moved out of the way to permit the transfer of the newly composed line to the first elevator.

Reference is now made to the means provided for causing the machine to carry out the second casting operation automatically. In the present instance, and as best shown in Figs. 3, 4, and 5,

there is associated with the actuating arm J 5 for the trip dog J, a rightangularly disposed cam H made fast to the rear end of a shaft H journaled in the depending arm of a supporting bracket H the latter being attached fixedly to the supporting rod J on which the arm carrying sleeve J 3 is mounted to turn. Normally, the high point H of the cam H occupies the inactive position shown in Fig. 3, i. e. out of engagement with the arm J but when the cam is rotated clockwise, its high point .H is brought into engagement with the arm J and the latter is rocked toward the left to move the trip dog J clear of the stop lever J so as to bring about the engagement of the main clutch. The cam H is moved to this active position by the operation of the pump plunger F in carrying out the first slug casting operation, and hence when the trip dog J is carried around to its starting position by the rotation of the main shaft, the arm J will prevent it from engaging the stop lever J and thus leave the clutch engaged to cause a second rotation of the main shaft and consequently a second casting operation. The operation of the pump plunger F in performing the sec ond casting operation, however, will move the cam I-I- counterclockwise to its inactive position as shown in Fig. 3, so that on this occasion, when the stop dog J is brought-again to its startingposition, it will be allowed to engage and-depress the stop lever J and thereby disengage the clutch to arrest the machine as normally.

The connectionsfrom the pump plunger F to the several parts which are operated therefrom will now, be described. As best shown in Figs. 2 and 5, there is located in the immediate vicinity of the pump plunger F a four-arm star wheel S, which has fast thereto aneight-tooth ratchet disc S The star wheel, with its ratchet, is rotatably mounted upon an enlarged hub portions of a rod or bolt S attached to a supportingv plate L mounted upon the machineframe. The rod or bolt S is extendedtothe left, as clearly shown in Fig. 7, and has rotatably mounted thereon a toothed actuating disc S for engagement with the ratchet S A compression spring S also carried by the bolt S acts constantly to maintain the actuatingdisc S in engagement with the ratchet S ,.but willpermit the actuating disc to yield latorally upon the bolt S y/hen: turned in a counterclockwise direction on its inactive stroke. The.

turni g-of, the disc. e :in a ,clockwise .direction,

which isv its active stroke, will advance. the ratchet,

S one tooth forward and impart a similar rotation tothe star wheel S. Briefly stated, thearrangement is suchthat, at each operationofthe;

toothed disc 8 the ratchet S will be advanced;

one-eighth of a rotation and thereby advance-the star wheel S one-eighth of a rotation, the latter acting at successive advances through two trains.

of connections al ernately to render the line removing means, the line delivering means and-that machine stopping means inoperative and opera,--

tive, respectively, whereby the machine will operate automatically to cast duplicate slugs from,

the consecutive composed lines.

The ratchet S is connected to the pump-lever F by means of a U-shaped bail F one end, of:

which is securedto the lever F by a clamp con-.

nection F The other end of the bail F adjacent;

the star wheel S, is formed with a hollow boss F in which there is provided a manually retractable spring detent F which servesas a means for connecting and disconnecting the bail F to'and:

from the actuating disc S the-latter being provided with an operating arm S adapted to be engaged by the detent F and. which is formed with a slot or opening S to permit a certain amount of lost motion.

The star wheel S, which controls'the setting of the first elevator stop P, the line delivery slide stop T, and the clutch control dog disengaging cam H, is connected with these three elements through two main trains of connections as 2.1

ready stated.

The connections between the star wheel S and the cam H consist of a lever H pivotally mounted on the bracket L, a right angularly disposedbellcrank lever H mountedon a shaft H journaled' 1n the bracket H and a link H which connectsthese two levers. The lever H is provided at its free end with a roller H adapted to ride on the periphery of the star wheel S, and which is held in engagement therewith by a spring H pulling upwardly on the lever H The lever H at its;

free end, is forked or bifurcated and engages with a pin H projecting forwardly from the side of the cam 5. By this arrangement, at successive H alternately in opposite directions, whereby the clutch control dog J is governed in the manner:

before described.

The other train of connections consists. of a lever M, pivotally mounted on a forwardly extending arm L of the bracket L, and a right angularly disposed bell-crank lever M pivotally mounted on an angular extension L of the bracket arm L The lever M is provided at its:

free end with a roller M adapted to, rideon the periphery of the star wheel S in the same manner as the roller H of the lever H it being held inengagement therewith by a spring M connected to one arm of the bell-crank M and to the ex tension L of the bracket L. At one end, the bellcrank lever M is forked or bifurcated (like thelever H and engages the end ofthelever (see Fig. 3), a certain amount of play thus being allowed between theselevers in operation. Con,- nectedto theother end of the bell-crank lever Ml aretwo rods M and M which connect it with the bail P carryingthe first elevator ,stoppiece. P, and the arm T of. the line delivery stop-leverv respectively,. he. arrangementgbeing suchzthat.

as the levers M and M are rockedabout their pivots during the rotation of the star wheel S, the stops P and T are both moved into and out of active position alternately in the manner before described.

Referring now to the improved galley, it is provided with a plurality of compartments for hold-- ing the slugs in separate columns, in order that the duplicate slugs may be kept apart and thus obviate the necessity of sorting them out by hand later on. In the present embodiment, and referring particularly to Fig. 8, the inclined galley R is divided into upper and lower compartments R and R 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 R The inclined chute N, down which the ejected slugs pass to the galley, is provided with a guide N fastened to the machine by a suitable hinge n, which forms the right-hand side wall of the chute and which extends forwardly, as at N into the galley R. Another guide N is pivotally attached to the lower end of the left-hand side wall of the chute, and is connected to and spaced apart from the guide N by a bent link or rod N whereby the swinging of one guide about its pivot will bring about a corresponding movement of the other.

The connecting link N is rigidly secured to the left-hand guide N but has a sliding engagement with theright-hand guide N being disposed between the outer face of the right-hand guide and a bracket N secured thereto, thus enabling the two guides to partake of a differential swinging movement resulting from the diiference in location of their respective pivots. At this point it may be well to note that the differential movement is utilized to contract the space between the two guides when they are adjusted to direct the slugs into the lower compartment R the shorter guide N being caused to approach the longer guide N and thus act to deflect the slugs, as they pass between the guides, toward the right and away from the end of the upper flange or shelf B In order that the guides may normally be held in a position to direct the slugs into the upper compartment R the bracket N is provided with a depending portion N adapted to be held between the galley supporting bracket R and a raised 1 rib N formed on a resilient member N secured to the bracket R the engagement, however, being such that very little force is necessary to move the member N over the rib N when the guide plates N and N are swung from one position to another.

The operation of the chute guides N and N is effected by a plunger V, which passes beneath the guides and which is provided at one end with an upright pin V arranged to project through'a ringlet N secured to the bracket N on the outer face of the guide N The other end of the plunger V is in the form of a cam V adapted to be engaged by a roller V journaled in the bifurcated end of an extended bolt V which replaces the bolt ordinarily used to secure the upper end of the link V connecting the first elevator E to its actuating lever. the head of the stacking device R and is arranged to engage the outer face of the lower end of the guide N so that when the guides are moved to the right to direct a slug into the lower compart ment, the stacking device R is also carried'to the right out of the path of the slug. This pin or A pin or lug R projects from guides to their normal positions afterthe trash porter Edescends from line removing position its upward movement by the stop P, the roller V fails to engage the cam V and thus allows the guides N and N to remain in their position to the left, to which they have, in the meantime, been returned by the active stroke of the stacking device R Under such conditions, the slugs will be delivered into the upper compartment R being arrested by the upper flange or shelf R which extends far enough to the right to intercept the slugs at the time. The stacking device R is slotted at R to clear this upper flange or shelf B In the operation of the machine, when it is desired to cast duplicate slugs, the detent F is set to connect the star wheel S to the pump actuating lever F The first composed line is then delivered to the first elevator and the machine started in the ordinary manner. When the pump actuating lever F is moved downwardly to inject molten metal into the'mold for the casting of the first slug, the ratchet actuating disc S is moved in a counterclockwise direction in its idle stroke to pick up one tooth on the ratchet S and as the lever F is raised to itsnorrn'al position by the rotating cam F on the main shaft, the actuating disc S is turned in a clockwise direction one-eighth of a rotation, thereby advancing the star. wheel S one-eighth of a turn.

This fractional rotation of the star wheel S causes the rollers H and M of the levers H and M, respectively, to come to rest in the depressions s. Thereupon, the upward pull of the spring H on the lever H causes the latter to rock about its pivot, exerting a downward pressure on the connecting link H whereby the bell-crank H is rocked about its pivot and the cam H rotated in a clockwise direction to bring its high point H into engagement with the clutch control trip dog actuating arm J At the same time, the movement of the roller M into its depression (the one opposite from that of the roller H permits the pull of the spring M to rock the bellcrank M in a counterclockwise direction, thereby exerting a downward pull on the rod M to bring the elevator stop P into active position, and

releasing the pressure of the rod M on the arm T so that the leaf spring T may act to raise the As a'result, the line delivery slide C is prevented (bythe locking lever T) from delivering a new or second composed line to the first elevator E, the first elevator is prevented (by the stop piece P) from making a full ascent into line removing position and consequently preventing the removal therefrom of the first composed line, and the actuating arm J is cammed into active position to trip the clutch control dog J at the end of the first cycle of operation and thereby cause the machine to continue through a second cycle of operation.

When the first composed line is presented a scribed.

second time to the mold, and the pump lever F is actuated to inject molten metal thereinto for the casting of the duplicate slug, the ratchet actuating disc 8* is again operated to advance the star wheel 5 through another one-eighth rotation to cause the rollers H and M to ride up onto the peaks 5 of the star wheel arms. This further fractional rotation of the star wheel rocks the levers H and M against the tension of their springs H and M in directions contrary to those above described, causing a counterclockwise rotation of the cam H to disengage its high point H from the clutch control trip dog actuating arm J and a clockwise rotation of the bell-crank M to move the rod M upwardly and carry the elevator stop piece P out of active position, and to move the other rod M downwardly and swing the stop lever T downwardly against the pressure of the leaf spring T out of the path of the line delivery slide C.

As a result of this alternate operation of the parts, the first elevator E is permitted to make a complete ascent for the removal of the first line therefrom, the line delivery carriage C is unlocked and permitted totransfer into the first elevator the second or newly composed line, and the trip dog J is unaffected by the cam H and allowed to stop the (being its second) operation of the machine.

The continued fractional rotations of the star wheel S puts the parts through the same operacessive line until the recasting attachment is rendered inoperative by manually retracting the spring detent F The operation of the mechanism for delivering successively cast slug-s to different compartments in the galley has already been sufficiently dei to the mold, an assembler wherein the line is composed, means for transferring the composed line from the assembler to the transporter, and automatic means for locking the line transfer means against action until the machine "has-completed several cycles of operation, said locking means acting directly on the transfer means and independently of the assembler.
