4 Sheets-Sheet 4 Patented Nov. 24, 1936 SLUG CASTING MACHINE John H. Hilpman, Hollis, N. Y., assignor to Mergenthaler Linotype Company, a corporation of New York Application July 30, 1935, Serial No. 33,815

20 Claims.

This invention relates to line. casting machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler No. 436,532, wherein circulating matrices are selected and assembled in line together with expanding spacebands, and the line thereafter presented to the front of a slotted mold, expanded or justified between a pair of confining jaws, and finally, after the casting operation, elevated from the jaws and distributed.

In practice, it is necessary frequently to change the length of the slugs or linotypes produced, according to the width or measure of the. page or column to be printed. Consequently, the mold slot in which the slugs are cast is made variable in length, and one of the confining jaws is also made adjustable to correspond, so that lines of one length or another may be used at will.

The desirability of an adjustable line confining Q jaw also arises when the machines are equipped for quadding or centering, since here too, the

mold slot may be varied in length, demanding that the left hand jaw be adjusted accordingly;

and, even in some cases when casting from molds g; of normal length, it is desirable that the left hand jaw be adjustable as, for instance, in offset centering, i, e., when a line is centered with respect to an imaginary line offset from the true center line of the mold.

The present improvements provide for the adjustment of the left hand jaw to meet the various conditions stated, and such adjustments may be effected by the operator while seated at the keyboard, thus obviating the necessity of his leaving the keyboard to effect the adjustment, as has previously been necessary in machines equipped for quadding and centering, with the result that greater facility and speed is obtained in the operation of the machine.

As usual, the jaws are arranged to be moved one toward the other to effect the quadding and centering movements, the right hand jaw for this purpose being connected directly to the actuating devices operable in quadding, whereas the left hand jaw is connected to such devices through a banking block with respect to which the jaw is relatively adjustable. The left hand jaw is secured in its different adjusted positions by a toothed rod rotatably mounted so as to be moved into and out of engagement with a complementary toothed section on the jaw, the arrange ment being such that, when the toothed rod and section are in engagement, the adjusted position of the jaw is maintained, whereas when out of engagement, the jaw may be moved with respect to'the toothed rod to its different adjusted positions.

The toothed rod is journalled at one end in the banking block previously referred to and, as the block is moved during a left hand quadding or 5 a centering operation, said rod will move likewise. To accommodate this movement of the rod, it is arranged to telescope within a sleeve which extends through the right hand jaw, and which serves the additional purpose of rotating the rod 0 into and out of engagement with the left hand aw.

The setting of the left hand jaw in its different line receiving positions is effected by an adjusting rod secured directly to said jaw (not its banking block) and which telescopes into an adjusting sleeve likewise extending through the right hand jaw, the. telescoping arrangement ac commodating the movement of the adjusting rod during a quadding or centering operation, as in the case of the toothed rod. The adjusting sleeve is rotatable with respect to the adjusting rod and, in one angular position of adjustment, is coupled to the adjusting rod so that the left hand jaw may be moved to its different positions by adjusting the sleeve. and consequently the rod longitudinally, it being understood that during such adjustment, the sleeve will extend beyond the vise frame at the right. In another angular position of adjustment, the adjusting sleeve and the adjusting rod are slidable with respect to each other, not only to provide for the telescoping movement before alluded to, but in addition, to permit the sleeve to be returned to its normal position with- Y in the right hand jaw where it will be out of the way during the operation of the machine.

It might be stated here that the right hand jaw is slidable with respect to both sleeves in order that said jaw maybe moved along the sleeves during a centering operation or when quadding with the right hand jaw.

The improvements further contemplate the automatic disengagement of the toothed rod from its complementary toothed section in the left handjaw as the adjusting sleeve is coupled to .5 the adjusting rod (in which condition of the parts, the left hand jaw may be adjusted to its different line receiving positions) as well as the automatic engagement or re-engagement of the toothed'rod with its complementary toothed section as the adjusting sleeve is uncoupled from the adjusting rod. Provision is also made for maintaining the adjusting sleeve in its normal position out of the way during the operation of the machine.

A composed line of matrices and spaces when presented at the casting level is confined endwise between a pair of vise jaws A and B mounted in the stationary portion of the so-called vise frame C (Figs. 1 and 5), and which are formed with hearing portions A and B siidably mounted in suitable guideways in the vise cap so that the jaws may be moved horizontally toward and from each other during a quadding or a centering operation.

The movement of the jaws toward and from each other (see Figs. 1, 3 and 4) may be effected by quadding and centering mechanism such as that illustrated in the Frolander Patent No. 1,949,302. Suffice it to say here that the jaws A and B are operated in their movements toward and from each other through a pair of levers A and E the lever B actuating the right hand jaw directly through a link B and the lever A actuating the left hand jaw through a banking block C connected to the lever A through a link A and which actuates the left hand jaw in its different positions of adjustment, as will hereinafter be described. Either or both jaws may be connected for operation by the quadding mechanism to effect a quadding operation at the left or at the right end of the line or a centering operation as desired.

In order that the left hand jaw A may partake of the movement of the banking block C the two 3 are connected by a toothed rod D having a reduced portion at at its left end where it is journalled in the banking block and secured against longitudinal movement with respect thereto by a cap d pinned at the end of the rod and abutting against one face of the banking block and by a shoulder presented by the larger portion (1 of the toothed rod, abutting against the opposite face of the block C The toothed rod D extends longitudinally through the jaw A, which latter is drilled for the purpose and is recessed in its bottom portion to provide clearance for the block 0 As shown in Figs. 3, 13 and 14, the toothed rod D is formed with teeth D in two of its opposite faces, the other opposite faces D being flat and, when the rod is turned to the position shown in Figs. 3 and 14, the teeth thereon will interlock with a section of complementary teeth A formed in the left hand jaw A, in which position of adjustment the left hand jaw will move as a unit with the banking block as the latter is actuated during a quadding or centering operation. When the toothed rod D is turned through an angle of the flat portions D thereof will be brought opposite the toothed section A and, as the vise jaw immediately above and below the rod is cut away for clearance, as at D (Fig. 7), there will be no connection between the rod and jaw (see also Fig. 13) and the latter may be then adjusted longitudinally of the rod D to any position desired to accommodate lines of different measure.

From the standpoint of operation, the teeth on the rod D could be formed at right angles to the axis of the rod as shown in Fig. 1. Actually however, they are given a slight pitch as shown in I Figs. 13 and 14, merely as a manufacturing expedient.

The toothed rod D spans the space between the jaws A and B and at its right end enters a sleeve B arranged coaxially therewith and which extends through the right hand" jaw B (Figs. 2 and 16) The sleeve B is journalled at its right end in a bifurcated bracket F screwed to the vise frame and held against longitudinal movement with respect thereto in a manner hereinafter set forth. With this arrangement, the toothed rod, during a centering or a quadding operation involving the movement of the left hand jaw, will telescope within the sleeve B During a quadding or a centering operation involving the movement of the right hand jaw B, the latter will move with respect to the sleeve B the right hand jaw being slidable with respect to the sleeve for this purpose.

It might be stated at this point that the toothed rod D is adjusted to its different positions into and out of engagement with the complementary toothed section in the left hand jaw A by rotating the sleeve B and for this purpose the sleeve, at its left end, is equipped (see Figs. 3 and 6) with a pair of opposed inwardly projecting portions 1) presenting fiat surfaces that engage the flat faces D of the toothed rod D (Fig. 6). Consequently, as the sleeve is turned, so is the rod, theportions b serving the additional purpose of guiding the rod D during its telescoping movement within the sleeve. The means for rotating the sleeve to effect the adjustment of the rod will later be described.

The left hand jaw A is adjusted to different positions with respect to the toothed rod D by means which include an adjusting rod G projecting at its left end into the left hand jaw to which it is fixedly secured by a screw 9, and at its right end into an adjusting sleeve G somewhat similar to the sleeve B associated with the toothed rod D. As in the case of the toothed rod and its associated sleeve, the adjusting rod G telescopes within the sleeve G during a quadding left or a centering operation, and likewise, during a quadding right or a centering operation, the right hand jaw B slides with respect to said sleeve G The adjusting sleeve G is also similar to the sleeve 4 in that it is journalled in the bracket F and is adjustable rotatably from a normal position wherein the rod G is slidable longitudinally with respect thereto through 90 in a clockwise direction (looking at the machine from the right) into a position wherein the rod G is coupled to the adjusting sleeve. The sleeve G differs from the sleeve B in that it is adjustable longitudinally, and when it and the adjusting rod are coupled together, an adjustment of the sleeve will effect a corresponding adjustment of the left hand jaw.

The devices for effecting the coupling and uncoupling of the sleeve G and the adjusting rod G are illustrated in Figs. 8 to 11. As there shown, the sleeve G is slotted longitudinally for a short distance at its left end to receive a fiat key G secured in position by a screw 9 extending radially inwardly from the outer face of the sleeve, the key G thus presenting a raised flat surface on the inner face of the sleeve. The adjusting rod G likewise presents a flat surface G but throughout its entire length, and when the parts bear the angular relation illustrated in Figs. 8 and 10, the flat surfaces will be in contact, permitting the telescoping movement between the parts as previously mentioned. I

The adjusting rod G (Figs. 8 and 9) is also formed with a recess G near its right end which fits the key G and, when the key and the recess are directly opposite each other, the sleeve G may be turned through an angle of 90 to position the key in the recess, thereby coupling the members together. When the rod and sleeve are thus coupled, longitudinal adjustment of the latter will, through the rod, effect a corresponding adjustment of the left hand jaw.

It will be recalled that the left hand jaw A can be adjusted with respect to the toothed rod D only when the latter is disengaged from the complementary toothed section A in the left hand jaw, and accordingly mechanism is provided automatically to effect such disengagement as the adjusting sleeve G is coupled to the adjusting rod G; and after the jaw has been adjusted by the sleeve, the toothed rod is automatically reengaged with the toothed section on the left hand jaw to lock the latter in its newly adjusted position as the adjusting sleeve G and rod G are uncoupled.

The mechanism for eifecting such automatic adjustment (see Figs. 1, 2 and 16) includes a gear H splined to the jaw adjusting sleeve G and positioned between two arms 1 and f of the bracket F, said gear being arranged to mesh with a corresponding gear H likewise positioned between the two arms of the bracket F and pinned to the rod adjusting sleeve B The adjusting sleeve G (Fig. 5) is secured in its normal position against angular movement by a detent H pivotally mounted on the bracket F and formed with a projecting portion h engaging in a groove G extending the full length of the sleeve G the detent being held resiliently in this position by a spring I-I fastened at one end to a lug h extending laterally from the detent and anchored at its other end' to an eye I screwed in said bracket. The sleeve G is also held in its normal position against longitudinal movement likewise by the detent H which, in the normal position of the parts, stands in the path of and at the right of a pin G (see also Fig. 12) projecting radially from the sleeve. In order to complete the description of the parts, it is pointed out that the sleeve G is formed near its right end with an air vent g to permit the escape of air during the telescoping movement of the rod G therewith and also at said end with a handle J, within convenient reach of the operator, which facilitates the adjustment of the sleeve both longitudinally and angularly.

The operation of the parts is as follows:

In effecting the adjustment of the left hand jaw, the detent H (which is provided with a convenient upwardly extending portion for the purpose) is first moved out of engagement with the groove G in the sleeve G and the latter, by means of the handle J, rotated through an angle of 90 (see Fig. 15) to bring the key G into the recess G thus coupling the sleeve G to the adjusting rod G, this coupling movement, as just described, through the medium of the gears H, H and the sleeve B effecting the rotation of the toothed rod D out of engagement with the toothed section A in the left hand jaw A. The latter is now free and may be adjusted to a new position by sliding the sleeve G to the right the desired amount (see Fig. 16), as indicated by a pair of em scales G screwed in longitudinal recesses formed in the face of said sleeve. noticed that two scales are provided spaced 90 apart so that one will be visible to the operator in each angular position of adjustment of the sleeve G The correct adjustment of the jaw A is indicated by a pointer G (Fig. 1) cooperatu ing with the em scales and which is formed of an angular-shaped piece of metal having two arms 9' and 9 the arm g extending toward the scales and being the pointer arm, and the other arm 9 being secured by means of a screw and slot connection 9 in a groove f milled in the upper face of the bracket F, the screw and slot connection providing for a limited adjustment of the pointer.

The scales G are graduated in half ems reading from left to right, so that the reading will indicate the length of the line for which the line confining jaws are adjusted. Thus, if it is desired to set the jaws for a line of 20 ems, the sleeve G will be pulled out a distance of 10 ems or until the scale registers 20, which of course, is the proper setting (assuming a machine for a maximum jaw separation of 30 ems).

It might be mentioned here, that when the It may be teeth on the rod D have a slight pitch, as previously described, the slight movement imparted to the jaw A with respect to the rod, brought about as a result of rotating the rod a quarter turn between its locking and unlocking positions, is compensated by a proper adjustment in the position of the scales G".

After the left hand jaw A has been adjusted to the desired position, the sleeve G (while still extended) is rotated back to its normal position where it is arrested by the engagement of the detent H in the groove G (Figs. 5 and 17) and, during this operation, the sleeve G is uncoupled from the adjusting rod G and the toothed rod D rotated back into engagement with the toothed section A in the left hand jaw, thereby locking said jaw in its newly adjusted position.

It will be recalled that in the uncoupled condition, the adjusting sleeve G is slidable with respect to the adjusting rod G, thus permitting the sleeve G to be returned to its normal position within the jaw B where it is out of the way, merely by pushing the sleeve inwardly (see Fig. 18). As the sleeve is pushed in, its normal angular position is maintained by the detent H which remains seated in the groove G during the sliding movement. As the detent strikes the pin G in the sleeve, it is cammed upwardly, permitting the pin to pass beneath it, but thereafter immediately reseats in the groove, thus holding the sleeve both in its normal, angular and longitudinal positions, as previously described. This camming action of the pin is facilitated by forming the detent immediately adjacent the pin (see Fig. 12) with a pair of cam surfaces 9 and g the outer surface 9 having less pitch than the inner surface g With this arrangement, as the pin strikes the surface 9 as the sleeve is pushed in, the detent will readily be cammed upwardly, Whereas when the pin passes the detent, the latter, due to the greater pitch of the surface g will push the sleeve home and also prevent accidental withdrawal thereof. The sleeve Gr in its normal position, but with the jaw A set for a line of less than normal length, is illustrated in Fig. 18.

In order to reset the left hand jaw A to a different position, the same procedure is followed as just described, except that the adjusting sleeve G must first be pulled out to the setting corresponding to the adjustment of the jaw in order to aline the key (3: with the recess G in the adjusting rod, so that the sleeve can be rotated to effect the coupling of the members.

During a quadding operation involving movement of the left hand jaw, the toothed rod D and the adjusting rod G will telescope within their respective sleeves B and G and during a quadding operation involving movement of the right hand jaw, the latter will slide with respect to said sleeves which, at the time, are both locked against longitudinal movement. A centering operation which involves movement of both jaws, and which therefore gives rise to both of the conditions just stated, is illustrated in Fig. 19.

In a slug casting machine, the combination of a pair of line confining jaws movable one toward the other in quadding, a toothed rod for locking one of said jaws in diiferent positions of adjustment to accommodate lines of different measure and movable with said jaw during a quadding operation, and devices including a sleeve extended through the opposed jaw for effecting locking and unlocking of said jaw and rod and into which said toothed rod is adapted to telescope during a duadding operation with the first mentioned jaw, said second mentioned jaw being slidable with respect to said sleeve during a quadding operation with said latter jaw.

18. In a slug casting machine, the combination of a pair of line confining jaws movable one towardthe other in quadding, means for adjusting one of said jaws to different positions to accommcdate lines of difierent measure, said means including an adjusting rod secured to said jaw and a sleeve extended through the opposed jaw into which said rod is adapted to telescope during a quadding operation with said first jaw, and means for coupling said sleeve with the adjusting rod for conjoint movement to permit the adjustment of the first mentioned jaw, said second mentioned jaw being slidable with respect to said sleeve during a quadding operation with the latter jaw.

19. In a slug casting machine, the combination of a pair of line confining jaws movable one toward the other in quadding, and means for looking one of said jaws in different positions of adjustment to accommodate lines of different measure, said means including a toothed rod rotatably mounted for engagement with and disengagement from the adjustable jaw but movable with the jaw during quadding, and a relatively stationary sleeve into which the toothed rod telescopes during a quadding movement of the adjustable jaw, said sleeve being rotatably mounted and coupled to the toothed rod so as to rotate the latter in efiecting its engagement with and disengagement from the adjustable jaw.

20. In a slug casting machine, the combination of a pair of line confining jaws movable one toward the other in quadding, and means for adjusting one of the jaws to different positions to accommodate lines of different measure, said means including a rod fixed to the adjustable jaw and movable therewith both during quadding and adjustment, a rotatably mounted sleeve into which the rod projects at the end remote from the jaw, and coupling means between the sleeve and rod, said coupling means in one rotary position of the sleeve permitting the rod to telescope freely within the sleeve during quadding or the sleeve to telescope with the rod after a jaw adjustment, and in another rotary position of the sleeve providing for the longitudinal movement of the rod and sleeve as one in effecting the adjustment of the jaw.
