20 Claims.

This invention relates to slug casting machines of the general organization disclosed in U. S. Patent No. 436,532 to O. Mergenthaler, wherein circulating matrices and expansible spacebands are 5 composed in line, the composed line presented to a slotted mold where it is positioned between a pair of line clamping jaws, the line justified by effecting the expansion of the spacebands to fill out the space between the line clamping jaws which determine the length of the justified line, the mold advanced into contact with the line, and filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices and spacebancls thereafter separated and returned by a distributing mechanism to the magazines from which they started.

More particularly, the present improvements deal with devices for varying the expansion of the spacebands according to the varying conditions encountered in practice. When casting from lines of full length, if they are properly composedand contain their full or usual complement of spacebands, the drive of the justification bar is usually such as properly to overcome the frictional resistance offered by the spacebands and b-ythe spreading of the line and to expand the line to the extent necessary correctly to space the words in the line. For short lines, however,

say 10 or 12 ems in length, consisting of perhaps two words with one intermediate spaceband, or three Words with two intermediate spacebands, the drive of the justification bar is excessive as compared with the frictional resistance offered 5 by the spacebands and the line, with the result that the spacebands are forced to their maximum height, thus producing excessive spacing between the Wordswhich is especially noticeable on small matter. The same excessive spacing between words will also occur even with lines of full length if such lines are composed too loose, because in that event the resistance offered by the spaceb'ands, irrespective of the number contained in the line, will not manifest itself until all the loosen'ess in the line has been taken up by the expansion of the spaceb-ands.

To obviate the foregoing and other difficulties (referring now to an exemplary embodiment of the invention), there is associated with the rods that support the justification bar an adjustable cross head which acts by banking against a fixed part of the machine to limit the upward movement of the justification bar, and thus controls or limits the degree to which the spacebands may be expanded. In this way, proper spacing between the words is effected.

For properly composed lines of matrices of a given point size, the spacing between words should be approximately the same, but as printed lines vary in the point size of the letters of which they are composed, proper typography demands that the spacing between the words vary accordingly. For this reason, the cross head which acts tolimit the upward movement of the justification bar is made adjustable in accordance with the point size of the slug to be cast.

In the embodiment ofthe'invention disclosed, the adjustment of the cross head can be made either manually, or automatically under the control of the adjustable right hand trimming knife, which latter as is well known is settable in different positions to accommodate slugs of different point sizes.

The invention is applicable to machines equipped with quadding and centering devices or without them. In either case, the expansion of the spacebands may be varied to accord with the point size of the slug to be cast from the composed line, which is a characteristic feature of the invention. Ordinarily, the automatic control of the. justifying devices will answer all requirements, but in special instances, when this is not true, the manual control may be resorted to. In quadding or centering, the invention has added utility and especially when the line clamping jaws are free to move outwardly during justification of the composed line.

'As is well knownin machines of this character, the matrices and expansible spaoebands are composed inline in an assembler and thecomposed line transferred to a transporter orso -called ffirst elevator which descends to present: the line between a pair of clamping jaws and in frontof a slotted mold, the latter by a one-quarter rotation of a mold disc or carrier having been previously located in a horizontal or casting position: ,gJuse r tification of the line then takes place, i. e. the'long wedge portions'of the spacebands are-forced upwardly through the line causing it to fill out the distance between the line clamping jaws, and this is effected by the upward movementzof a so-calle'di justification bar A (Fig. 1) carried at the top of; two spaced vertical rods A and A and which en gages the long wedge portions of thelspacebands at the bottom. Justification takesplac'e in two stages, and the matrices are properly alined with the mold between stages, in wellknown'manner; During the first stage of justification, the justifilcation bar moves up at an angleso that the spacebands at the right of the line are expanded in greater degree than those at the left, During the second stage, the bar'A isdriven up in a horizon tal position, the spacebands atthe left being act-z ed upon first (since these now extend-belowgthose at the right) but all ofthespacebands' at the completion of justification have the same degreefof expansion. In order to accommodate this variable movement of the justification bar A;;the-vertical rods A and A through which the. drive theretois imparted, are operated independently through cam controlled spring operated levers A and A (Fig. 1) all in well known manner. 1

Coming now to the present invention, there'is mounted on the justification rods A and A (see Figs. 1, 2 and 3) a cross head B settablein differ entpositions of adjustment along said rods .de.:- pending upon the degree of expansion desired inthe spacebands. The cross 'headB' is equipped with a pair of banking screws b threaded "into the top and at the opposite ends thereof, and which bank against a fixed cross piece C on'the vise frame as the ro-ds'A A move upwardly during justification. In this manner, the upper-. most position of the justification barlAzis .p'os'i-' tively determined and consequently the degree to which the spacebands will be'allowed'to :expand. "To insure proper cooperation between the 1 cross bar C and the banking screws b; the latter are adjustable and are locked in their positions 0 adjustment by locking nuts 11 (see Fig. 3);:-

The crosshead B (see Figs. 3, 4 and 5) is formed apair of toothed bloCksB? and'B arranged-to engage correspondingly toothed bars A and A mounted in recesses formed in said ro-ds'n and I A The toothed bars A and A are suffiiently T of the cross head B.

The toothed locking blocks B and B ('see Fig.

long to accommodate the full rangeof adjustment 3) areadapted to be moved into and out o'f engagement with their'respective 'toothe'drodsnf and A simultaneously, and to this 'end they are connected with a. rocking plate B pivotally mounted on the cross head B and located adjacent the center thereof in :a recess provided for the purpose. The block B is formed at the right end the body portion B in a manner similar to the slide 13 and is connected at its opposite endin like .manner to the rocking plate B but at a point belowthecenter thereof. The arrangement is such' that as the slide B is'moved to the left, the slide B will be moved toward the right, thereby simul- Bifromthe rods A and A Likewise, when the slide B is returned to the'right, the slide 13 will be returned to the left, thus effecting the looking engagement of the blocks B and]; with the rods A and A simultaneously. Normally, the blocks are. held in looking engagement withtheir respective rods by a spring B housed in a recess B formed in an inclined boss at the top of the cross head and pressing against the enlarged head of a pin B that extends through the boss at the taneou'sly disengaging the locking blocks B and i base of the recess B 9 and which banksagainst 7 the 'slidejBf', at the end thereof adjacent therocka ing plate; The spring B is held in the" recess by a screw B threaded intolthe boss and which serves.

also to adjust the force exerted bythespring on the-pin B 1] It will be recalled that the justificationrods A and A have a variable movement upward during justification 'for reasons hereinbefore mentioned, and as the cross'head B moves as a unit with the right hand rod A by virtueof the fact that the locking block B associated therewith'is formed integral with the slideB' provision 'is respect to its actuating slideB the connection between the two members for this purpose being; in 'the'form of tongue and groove interengaging' devices B (see Figs. 5 and 6). ,7 V V v V The block B in the normal position of the parts (see Fig. 3) banks at its bottom against the upper end of a banking screw b threaded into a lug 12 formed atthe bottom of the cross head B,

being held in such positionaby' a compression spring b seated in a recess'b formed'in thecross head B above the block and pressing at its. lower end against said block where it enters a. shallow recess 1) that serves'to' anchor the spring a properly in position at this point.

rod A moves upwardly at} a varying rate with respect to the cross head B,,the block B will move along with it (against; the action of th'efspring Now, as the;

I1 untilitbanks againstan overlying banking surface b presented by' the oro'sshead B,.thus causing. the arrest of the block B5 and consequently thQ IOdlA In this way, the arrest of rod A which determines the position of the left The amount by which the spacebands' are allowed to expandis'controlled by, adjusting the cross'hea'd'B to different positions up and down the rods A and A Before this can be done, howeventhe cross head must be disengaged from the rods A and A and this as previously stated is effected by. actuating the slidesB" and B against the tension of the spring B The slide B is moved to the left or its unlocking position through the medium of a horizontal slide D (Figs. 2, 4, and 6) resting in a groove formed in the sleeve B at the front, andhaving at one end, a thickened portion D extending through a slot B in the body portionof the cross head, where the slide D is secured to the slide B". At its opposite end,-the slide D is equipped with a roller D which is acted upon by a cam E pivotally mounted on a vertical axis in a bracket C secured to the vise frame C It will be noted that the active surface of the cam E is sufficiently long in a vertical direction to remain in contact with the roller D throughout the entire range of movement of the cross head B either during adjustment or operation of the latter. The normal 7 position of cam E, e., when the blocks B and B are in locking engagement with the rods A and A is shown in Fig. 5, but when it is desired to effect disengagement of the blocks from their respective rods, the cam E is turned in a clockwise direction, looking at the parts from the top (see Fig. 6), to bring a high portion of the cam opposite the roller D and when this occurs the slide D'will be actuated to the left with the results hereinbefore set forth.

;The cam E is turned'in a clockwise direction through the medium of a :horizontal reciprocable rod F, slidably arranged in the vise frame and adapted when moved to the left to engage the cam in a, notch provided for the purpose. The rod F is moved positively to the left to effect the disengagement of the cross head from the rods A and A either manually, or automatically under the control of the means for adjusting the trimming knives, butis returned after the adjustment of the cross head by the spring 13 through the agency of the intermediate slides 13' and D and the cam E.

The manual adjustment of the reciprocable rod F (best illustrated in Figs. 2, 6,7 and 8) is effected by a lever G located at the right of the vise frame, beneath the knife adjusting devices, and pivoted on apin G carried by an extension 0 of the bracket C The lever G at the left of the pivot is formed with a cam shaped arm G adapted to engage a roll F rotatably mounted in a yoke F formed at the right end of the horizontal rod F. As the lever is turned in a counterclockwise direction (Fig. 2) the arm G thereof will bear against the roll F and force the rod F to the left, with the consequent disengagement of the cross head B from the rods A and A in the manner previously described.

I When the parts have been disengaged, the cross head is free to be adjusted along the rods A and A and for this purpose another lever G is provided likewise pivoted on the pin G The lever G has a long arm G extendingto the left and formed withabifurcated portion G straddling a pin B mounted in a lug B formed on the sleeve B of the cross head B (Figs. 2, 3, 5, and 6). According to this arrangement, the movement of the lever G in a clockwise direction (Fig. 2) will raise the cross head, while movement in the opposite direction will lower it. Both the levers G and G are equipped with finger pieces g and 9 respectively, which lie one directly above the other so that both may readily be operated by one hand in making the adjustments just alluded to. Of course, as soon as the cross head has been adjusted to the desired position, the release of the lever G will allow the cross head and rods A and A again to enter into locking engagement.

The position of adjustment of the cross head B is indicated on a scale Hmounted at the front end of a fore-and-aft extension C of the bracket (3 (see'Figs. 1, 2 and 8), by a pointer g carried on an arm G that extends forwardly from the hub of the adjusting lever G The scale H is graduated from O to 10 giving a suitable range of adjustment for matrices ranging in size from 5 to 14 points, since above 14 points the spacing between words is usually constant. However, the scale is merely arbitrary and any other could be adopted if desired. The zero position of adjustment is fixed by the banking of the arm G of the lever G3 in its topmost position against a stop C projecting rearwardly from the bracket C and in this way a certain amount of spaceband expansion is insured even for matrices of the smallest point sizes.

Provision has been made whereby all the above adjustments may be carried out automatically, and in the exemplary embodiment shown the mechanism for adjusting the right hand trimming knife has been utilized for the purpose.

' In the commerical Linotype machine, the right hand trimming knife (see Figs. 2, 4 and 7) is carried by a block J slidably arranged in a bracket J secured to the vise frame. The block J and consequently the knife is urged under spring tension away from the left hand knife, and its position isdetermined by one or another of a series of banking studs J of different lengths carried by a disc adjustable through the medium of a knob J (Figs. 1 and 4). In order to effect the adjustment of the knife block, the knob J must first be pulled out toward the right before the different banking studs can be brought into registry with the knife block. The construction of the knife adjusting mechanism is more fully disclosed in U. S. Patent No. 1,656,639, dated January 17, 1928, if further details thereof are desired.

This outward movement of the knob J and the different adjustments of the knife block J have been utilized in the automatic setting of the cross head B. A number of the parts used in the automatic setting of the cross head are common to the devices for manually setting the parts; those that are not are all carried by a bracket cor casting K mounted on the knife block support J by means of four set screws k, W, k and 70 two extending inwardly, one from the front and the other from the rear portions of the bracket and banking against a portion of the knife block support, and the others extending one downwardly and one upwardly and banking against another portion of the knife block support (see Fig. '7).

As the knob J is pulled outwardly prior to the adjustment of the knife block, a collar J thereon (see Figs. 2 and 8) engages the upper end of a lever K pivotally mounted adjacent its center and at an angle with the vertical, in an offset portion K of the bracket K, causing the lower end of said lever to be moved to the left in the direction of the vise frame. The lever K at its lower end is pivotally connected to a rod K slidably supported in two depending lugs k and k of the bracket K. By reason of this connection, the rod K likewise is moved to the left under the influence of the lever K and this movement,

through a rigid offset connection K4, is transthe ,same'function in the automatic setting of the parts.

When the knob J has been withdrawn, it is 1 turned in one direction or another to set the knife block J, and the setting of the latter in turn effects the setting of the cross-head with respect to the justification rods. This setting 7 is brought about through the medium of a stud point size.

K projecting forwardly from the knife block J (see Fig. 7 through a slot K formed in the knife block support; and which acts on the upper end of a lever. K pivotally mounted at a point some.-

what above its center on an upstanding portion K of the bracket K. "The lower portion of the lever K is bent and rebent to clear a portion of the bracket K,'and is pivotally connected at its lower end, by means of a retractible'pin K with the arm G of the adjusting lever G According to this arrangement, as the knife block moves to the left to, effect a closer. spacing of the knives for slugs of smaller point size, the stud K will turn the lever K in a counterclockwise direction (Fig.2) and it in turn will move the lever (33 in a clockwise direction to raise the cross head, the lever G acting in the same manner as it does when the parts are manually adjusted.

When the knife block is moved outwardly to set the knives to accommodate slugs of larger point sizes,the lever K will move in a clockwise direction under the influence of a tension spring K fastened to said lever near the lower end thereof, andanchored inthe bracket K. This movement of the lever K will turn the lever G in a counter clockwise direction to lower the cross head B, which of course is the way said lever acts When the parts are manually adjusted. The parts are so proportioned that a change in setting of the knives from one point size to another, will effect a change in the setting of the cross head-B corresponding to that which would occur if the parts were manually set for an equivalent change in After the knives have been adjusted .and consequently the position of the cross head B, the knob J will be returned to'its inner normal position and this in turn will allow the locking engagement between the cross head and the rods A and A to be restored.

' It will be recalled that in the present arrangement, the range of adjustability of the cross head has been confined to those cases wherein'the size of the characters range between 5 and 14 points tions have been placed upon the mechanism-when the parts are automatically set.

to accommodate a slug larger than 14 points,'the movement of the lever K in a clockwise direction is arrested by a stud K threaded into the bracket Kand against which the leverK banks, and in this way the lowermost position of the cross head B is determined and consequently the maximum degree of expansion of which the spacebands can partake for, this setting of the parts.

If it is desired to cut out the automatic adjustment of the parts, this may be readily done by withdrawing the pinK from the arm G of the lever G and also the pivot'pin by which the lever K that controls the lockingand unlocking devices is held in the bracket arm K (see Fig. 8)

Thusas shown 7 'in Fig. 2, when the righthandknife has been set 1 Although in describing the present improve-Y ments their chief application has been cited in connection with lines of short -l'ength,. it is' ap-" parent that they act quite independently of the;

length of the lineand can be used whenever it is desired to maintain uniform spacing of the words throughout a series'of lines, even when the latter re 'of full length. V
