Turner, Little Neck, N. Y., assignor to Intertype Corporation, Brooklyn, N. YL, a corporation of New York Application August 15, 1933, Serial No. 685,259 In Germany March 14, 1933 14 Claims.

The present invention relates to improvements in typographical machines and more especially to those of the Well-known class as generally shown and described in U. S. Letters Patent No. 436,532

granted September 16, 1890, wherein character bearing matrices and expansible spacebands are assembled in lines which are introduced between the jaws of a vise, the lines are justified by expansion of the spacebands therein, and type bars or slugs are cast from the lines, after which the matrices are distributed and returned to a magazine from which they were drawn and the spacebands returned to their place of storage, and the invention relates more particularly to developments of machines of this class having means for quadding at either end of a matrix line by closing one or the other vise jaw against the respective end of the line and for centering the line by closing both jaws against the ends of the line.

In machines of this class, the spacebands are justified ordinarily in two operations, the first of which spreads the line endwise to take up looseness therein by expanding the well-known slidable wedge spacebands, and the second of which operations finally tightens the line immediately prior to the casting of the type bar or slug therefrom. 'The first justification is effected customarily by advancing the so-called justification bar upwardly against the depending ,spaceband wedges, the bar, during this operation, being inclined downwardly toward the left end of the matrix linesoas to engage the spaceband wedges successively from right to left, thus allowing each successive spaceband to creep alongthe justification bar naturally in the direction in which its upper end, together with the matrices, ismoved, due to progressive expansion of the line'from-right to left.

Such justification is satisfactory when it is only reguired'tha't all matrix lines'be spread or ;ju sti fied from right to left, whichisusual when justifying 'full'lines, but when'the machine is arranged to quad out lines composed to .less thanfull'measure 'for which the machine .is 'set, byrmoving one or the other or both visejaws, a new condition arises which makes it impracticable to justify lines always with the justificationbarinclined in the same direction. Since theright'handvisejaw inthe machine normally. stands'in'a-definite position known as line receiving position and all matrix lines are delivered between the fja-ws-wit-h the matrix at the right hand -endthereof alined vertically .with theface of ;this jaw,:if this jaw is moved to "theleft to "quadoutthe right hand end of a line, as for example a short line at the end of a paragraph, the line of matrices is also moved to the left until its left hand end contacts with the face of the left hand vise jaw, but since the left hand jaw is held against a stop in the machineto fix the left hand end or beginning of the line in column alinement with other lines, any spreading due to justification of the matrix line must take place toward the right. Similarly, the left hand jaw in the machine may be arranged to quad out the left end of a matrix line, as for example, the first line of a paragraph,to provide the usual paragraph indentation or to quadout at the beginning of lines intended to alirie at the right margin of the printed page, in which case the right hand jaw remains stationary against a stop in the machine to fix the right hand end of the line, so that any spreading of the'matrix line, due to justification, must take place towardthe left. In machines adapted for quadding, the particular jaw which is moved inwardly against the matrix line to effect the quadding out of the unfilled portion of the line is capable of moving outwardly under the influence of expansion of the spacebandsin the line to effect justification, and the spreading of the line during such expansion of the spacebands will be in a direction toward the movable jaw. Consequently, if justi- .fication is to spread a line to the right, then the justification bar should be inclined downward- 8.5 1y to the right to permit the natural creep of the spacebands in that direction, and 'if justification is to spread the matrix line to the left, then the justification bar should be inclined downwardly to the left for the same reason. Also, if a .line is to be quadded outat both ends, as where themachine is arranged to move both vise jaws equidistantly toward one another to effect centering of the lines, then the justification bar need not be inclined in either direction but should vbe horizontal, since the spreading of the line will then take place both .to the right and the left.

The primary object of the present invention .is to provide practical and simplemeans forsetting the justificationbar inan appropriate ositionto effect justification satisfactorily and effectively according :to whether a matrix line is being quadded out witheitherone or both of the vise jaws, the justification bar, according to the .present invention, being so. mounted and operated that it may beinclined downwardly either toward the right hand or the leftihand vise jawaccording to whether quaddingis beingdone with the right hand or: the left hand jaw, whereby the inclination of the justificationibar twillfavor thetcreep 1,10

of thespacebands in the direction in which the line is spread during justification, thereby avoiding strain or bending of the spacebands when forced upwardly through the line, and the justification bar is capable of occupying a horizontal position when quadding or centering is being done with both vise jaws, thereby facilitating the creep of the spacebands toward both ends of the line.

A further object of the invention is to provide control means between the justification bar and the devices for selecting the vise jaw or jaws with which it is desired to quad, whereby the justification bar will be set automatically to incline downwardly toward the particular jaw selected for quadding movement, or the justification bar will be set automatically in horizontal position when the jaw selecting means is set for quadding or centering with both vise jaws.

To these and other ends the invention consists in certain improvements and combinations and arrangements of parts all as will be hereinafter more fully described, the features of novelty being pointed out more particularly in the claims at the end of this specification.

The present invention is applicable to typographical machines having means of different forms for quadding or quadding and centering of matrix lines, the invention being shown in the present instance applied for example to quadding and centering means of the kind shown and described in the prior application of Samuel E. Sperry, Serial No. 612,349 filed May 19, 1932, 1 and 2 representing the right hand and left hand jaws of the vise in the machine, these jaws being guided to slide toward and from one another in the vise frame 3, and 4 represents a rack'bar which is connected by a link 5 to an arm 6, the latter being pivoted at '7 and provided with an arm 8 which is connected by a spring 9 to a suitable operating part of the machine so that the arm 6 and its connected parts constitute a power operated device for closing either or both of the jaws against a matrix line M containing the usual wedge or expansible spacebands S afterthe same has been lowered into position between the vise laws by the descent of the first elevator 10 in the manner usual in machines of this class. The rack bar 4 is adapted to be connected to and disconnected from the right hand jaw 1 by a pin 11 mounted to reciprocate in the block 12 ca ying the jaw 1, this pin, when moved in one direction engaging in an aperture 13 in the bar 4 and thereby connecting the latter to the jaw 1 so that said jaw will be operatively connected to the bar 4, and when the pin 11 is shifted in the opposite direction, it will be retracted from the aperture 13 in the bar 4, thereby disconnecting the latter from the jaw 1, and the pin will be engaged in alocking recess 14 formed in the vice frame 3, the jaw 1 being then looked in" its normal or fully open position against its stop 15. The bolt 11 is shifted by a stud 16 projecting therefrom and engaging a lever 17, the latter being pivoted at 18 on the jaw block 12 and having an open fork 19 at one end to receive a pin 20 carried by a link 21, the latter being slidably mounted on the vise frame by a screw 22 engaging in a slot 23 in the link 21 and the link 21 being pivotally connected at 24 to an arm 25, the latter being fixed on a shaft 26 rotatably mounted in suitable bearings on the top of the vise frame. The shaft 26 has an operating handle or lever 27 fixed thereon whereby said shaft may be rotated into different positions, and the shaft 26 carries a pointer 28 arranged to cooperate With a suitably graduated scale 29 which appropriately indicates the different settings of the shaft 26. The shaft 26 also has an arm 30 fixed thereon, this arm carrying a pin 31 arranged to operate in a cam slot 32 formed in a lever 33, this lever being pivoted at 34 on the vise frame and carrying at its opposite end a pin 35 which is operatively connected to the upper end of a spindle 36 which is shiftable vertically in the vise frame and carries a rotatable pinion 37 at its lower end which is movable into and out of engagement with rack teeth on the rack bar 4 and rack teeth on a rack bar 38 fixed to the block 2 which carries the left hand jaw 2, the cam slot 32 being of such shape that the pinion will mesh with both rack bars when the shaft 26 is set forquadding with the left hand jaw 2 and for centering and will be disengaged from said rack bars when said shaft is setfor quadding with the right hand jaw 1.

By the arrangement described, when the shaft 26 is rotated by the handle 27 to bring the pointer 28 opposite to the legend L. H. 632., the link 21 will be shifted in a direction to withdraw the pin 11 from the aperture 13 in the rack bar 4, thereby disconnecting the right hand jaw 1 therefrom and at the same time the arm 30 on the shaft 26 will operate in the cam slot 32 in the lever 33 to rock the latter in a direction to move the pinion spindle 36 downwardly, thereby engaging .the pinion 37 with the rack bars 4 and 38, the parts being shown in this position in Figures 4, 5 and 6 and the device being then set for quadding with the left hand jaw 2 which is then connected to the actuating rack bar 4 through the pinion. When the shaft 26 is rotated by the handle 27 to bring the pointer 28 into register with the legend Center on the scale 29, the arm 25 will pull the link 21 in a direction to engage the pin 11 in the aperture 13 in the rack bar 4, thereby connecting this rack bar to the right hand jaw 1, and this rotation of the shaft 26 will, at the same time move the pin 31 on the arm 30 in the cam slot 32 in the lever 33, but this cam slot is of such a shape that the lever 33 will not be rocked by such movement of the pin' 31 and hence the pinion 37 will remain in mesh with both rack bars 4 and 38, so that when the shaft 26 is set in this position, bothjaws 1 and 2 will be connected to the rack bar 4 and its operating arm 6 and will move simultaneously for centering a matrix line. Rotation of the shaft 26 by. the handle 27 to bring the pointer 28 into register with the legend R. H. Q. on the scale 29, causes the arm 25 to. impart further movement to the link 21 which merely moves the pin 11 further into the aperture 13 in the rack bar 4, this rack bar thus remaining in connected relation with the right hand jaw l, but the arm 30 on the shaft 26 will move the pin 31 thereon into the inner end of the cam slot 32 in the lever 33 and will rock this lever in a direction to lift the pinion 37 out of mesh with the rack bars 4 and 38, the right hand jaw 1 being then connected to the rack bar 4 but the left hand jaw 2 being disconnected therefrom, the parts being then set for right hand quadding'. From the foregoing it will be understood that the jaw closing mechanism may be set for quadding with either the right hand or the left hand jaw, or for quadding or centering with both jaws, and it will be further understood that the portion or portions of the mold cavity not closed by the matrix line will be closed by the quadding movement of the movable jaw or jaws. As in the prior application hereinbefore referred to, a locking pawl 39 pivotally connected to a lever 40 is operated by the justifier during its justifying strokes and is engageable with ratchet teeth 41 on the rack bar 4 to limit the extent of outward movement of the jaw or jaws under the expanding influence of the spacebands in the line during justification thereof.

The justifier comprises a justification bar-'42, a justifior frame 43, rods 44 guided to move vertically in the vise frame, and the usual first and second justification levers 45 and 46 respectively. The frame 43 is bored at its ends to rigidly receive the upper ends of the rods 44, which are rigidly secured in said frame by fastening pins 43 and the justification bar 42 is formed on its under side with a web 47 which fits movably into the frame 43 for which purpose the latter is hollowed out at the center as shown in Figure '7. The web 47 has a cross-pin 49 fixed therein which is movable in vertical slots 48 in the sides of the frame 43, said pin and slots permitting the justification bar 42 to rest in a horizontal position on the top of the frame 43 as shown in Figure 3 or to be tilted into either of the inclined positions represented by the dotted lines in Figure 1 or as shown in Figure 2, the pin 49 however preventing displacement of the justification bar from the frame 43. The web 4'7 on the justification bar is provided at opposite side of the pin 49 with projections 50 and 51, and a pin 52 extends through the frame 43 at a point between said projections on the web. The brace bar 54 is pivotally connected at its lower end to a sleeve 55 which latter is slidable vertically on the respective rod 44 so that it will be raised and lowered by the first justification lever 45, and the upper end of the brace bar 54 is provided with a fork 55 and is movable transversely and vertically in the hollow central portion 57 of the frame 43, so that the fork 56 may be set to engage one or the other of the projections 50 and 51 on the web 47 of the justification bar 42 or may be set to engage the cross-pin 52 fixed in the frame 43. By this arrangement, when the cross-brace 54 is set to engage the projection 51 on the justification bar 42, ascent of the crossbrace under the action of the first justification lever 45 will cause the justification bar to be tilted so that it is inclined downwardly toward the jaw 1, as shown in Figure l, and when the brace bar 54 is set to engage the projection 50 on the justification bar 42, the latter will be tilted so that it will incline downwardly toward the jaw 2, as shown in Figure 2, during justification. When the brace bar 54 is set in a position to engage the pin 52 fixed in the frame 43, the latter will be lifted while the justification bar rests horizontally thereon during justification, as shown in Figure 3.

Since the brace bar 54 does not support the frame 43 in normal position, nor will this frame be supported by the sleeve 55 which is loose on the respective rod 44 instead of being pinned thereto as usual in machines of this class, stop pins 44 are fixed in the rods 44 and arranged to seat on the vise frame 3 when the frame 43 is in its normal lowered position and thereby support said frame in normal position, as shown by the full lines in Fig. 1.

The setting of the brace bar is preferably effected automatically by the setting of the handle 27 by the operator to quad with either jaw or to quad or center with both jaws, for which purpose a slide 58 is guided by a pin 59 operating in a slot 60 therein to move horizontally on the vise frame, this slide being provided with a guide 61 in which the upper end of the brace bar fits and is shiftable vertically, the slide 58 being pivotally connected to the lower arm of a bell crank lever 62 which is pivoted at 63 on the vise frame and the upper arm of which is pivotally connected to a rod 64, the latter being ivotally connected at its upper end to an arm fixed on the shaft 26, these parts being so constructed and arranged that when the handle 27 is set'for quadding with the right hand or the left hand jaw, the slide 58 will be shifted to bring the brace bar 54 into position to engage the projection 50 or the projection 51 on the justification bar 42 and when the handle 27 is set for quadding or centering with both jaws, the slide 58 will occupy an intermediate position and will set the brace bar 54 to engage the pin 52 in the frame 43.

Ihe operation is as f0llows:-In Figure 1, the full lines show the justification bar 42 in normal position as when the machine is idle. The dotted lines in this figure represent the position of the justification bar during the usual first justification of a line when the operator has set the handle 27 at the RI-IQ indication, whereby matrix lines set too short to justifyto full column measure will be quadded out at the right hand end. Under such conditions, the connec-- tions 53, 62, 64 and 65 between the shaft 26 carrying the handle 27 and the brace bar 54 have set the brace bar in position to engage the projection 51 on the web 47 of the justification bar 42. Accordingly, when the first justification lever 45 is lifted in the usual way to move the justification bar upwardly, the brace bar 54 acting on the projection 51 thereon tilts or inclines the justification bar so that it inclines downwardly toward the right hand jaw 1, as indicated by the dotted lines in Figure l, and at the same time, the brace bar 54 lifts or raises the frame 43 and rods 44 upwardly as a unit. Since the spread of the line is toward the right hand jaw 1 under the conditions described, such inclination of the justification bar is proper to allow the spacebands to creep naturally down the incline.

Figure 2 represents the condition when the handle 27 has been set to the LHQ indication to quad out the left hand end of a line, in which case the connections 58, 62, 64 and 65 have swung the brace bar 54 so that its upper end is in position to engage the projection 50 on the web 4'7 of the justification bar 42. Accordingly, when first ill-5 justification occurs, the brace bar 54 will rise and act on the justification bar to incline it downwardly toward the left hand jaw 2 as shown in this figure, and this incline of the justification bar will be proper to allow a natural creep of the spacebands toward the jaw 2.

Figure 3 represents the condition when the handle 2'7 has been set at the Center indication, in which case there will be an equal spread of the line in both directions during justification. Under this condition, the connections 58, 62, 64 and 65 have brought the upper end of the brace bar 54 into position to engage the pin 52 rigid in the frame 43, and hence, when first justification occurs, the brace bar 54 will engage this pin rather than the web 47 of the justification bar, so that the justification bar will merely rest in horizontal position on the frame 43 and the lifting of this frame by the rise of the brace bar 54 will therefore carry the justification bar upwardly while occupying the horizontal position shown in Figure 3 and allowing a natural creep of the spacebands toward both of the jaws.

In respect to operation of the justifying means during second justification, it will be understood that as in the usual machine the second justification lever 46 moves upwardly slightly in advance of the first justification lever 45 whereby the frame 43 is moved upwardly with the spaceband expanding member 42 resting thereon in horizontal position. The upward rise of the first justification lever 45, and with it the brace bar 54, will bring the head 56 of the latter into engagement with one or the other of the projections 50, 51 at the completion of the second justification stroke, so that the frame 43 will be pressed upward yieldingly during second justification and during the casting operation while supported by the rod 44 of the second justification lever and the brace bar 54. a

It will be seen from the foregoing that the present invention provides means to effect automatic correlation of the incline of the spaceband justification bar and vise jaw toward which spread of the line due to justification of the spacebands is to take place, although it will be understood that the invention comprehends primarily the provision of means for adjusting the justification bar to incline it in the desired direction according to which end of the line is free to move outwardly when the spacebands are expanded, and such means is not necessarily controlled by the devices for selecting the quadding jaw but may be controlled or set independently thereof in order to obtain the above described advantages in the spreading or justification of the matrix lines.
