16 Claims.

The present invention relates to improvements in typographical machines of the well known class wherein assembled lines of character bearing matrices are clamped between a pair of vise jaws in front of a mold for the casting of type bars or slugs therefrom, and it relates more particularly to devices now used on machines of this class for automatically quadding composed lines of matrices at either or both ends, examples of such devices as applied to machines of this class being disclosed in U. 5. Letters Patent Nos. 1,964,695 granted June 26, 1934 and 1,970,527 granted August 14, 1934.

The primary object of the present invention is to broaden the scope or range of operation of machines equipped with such devices whereby the machine, in addition to handling automatically ordinary full length matrix lines which are to be cast to the full column width or line measme for which the vise jaws are set and which do not require quadding, and shorter lines of random or irregular length with or without space bands and requiring quadding to fill out the remaining blank space at either or both ends, will also handle automatically short lines which require a definite amount of quadding so that they will cast exactly to a desired short line measure and thus be of the proper length to fit around cuts or the like inserted in the column of print at either side thereof.

To this and other ends, the present invention provides means for setting the quadding mechanism in condition to function in the required manner, such means being adjustable and governing the conditions under which cooperation can take place between the jaw closing mechanism and a jaw stop device for locking and retaining the vise jaw or jaws in different closed or quadding positions to which they may be moved by the closing mechanism. The jaw stop device, according to different settings of the adjustable control means provided by the present invention, will function automatically either to retain the jaw or jaws in random closed or quadding positions with respect to lines composed too short to justify to definite line measures, and lines which do not contain space bands, or to locate and retain the jaw or jaws at different selected quadding positions with respect to lines composed short of a definite short line measure within a maximum amount allowed by the control means.

will understood of course that whenever it is desired to cast lines exactly to a definite line measure, which may be the full line meas- 1936, Serial No. 97,047

ure corresponding to the normal open or line receiving position of the jaws or a shorter line measure, the well known expansible space bands will be employed in the lines, as usual, to justify the lines to the required length. It will also be understood that in carrying out the invention, the particular form of the jaw stop device and jaw closing mechanism and manner in which these elements cooperate to lock and retain the jaw or jaws in different closed or quadding positions may vary according to the nature of the quadding mechanism employed. The principal consideration is, that a control means be provided for governing the cooperation between the jaw stop device and the jaw closing mechanism whereby such cooperation will take place either at random quadding positions of the jaw or jaws or only when the jaw or jaws, after partaking of quadding movement, occupy one or another selected quadding position corresponding to a desired short line measure.

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.

In the accompanying drawings:

Figure 1 is a rear elevation of the vise jaws of a machine of the class referred to, provided with quadding mechanism embodying the present invention, one of the jaws being shown closed to quad a short matrix line and the control means provided by the present invention being set to permit a short line to justify exactly to a desired length before the jaw stop device operates to lock and retain the jaw at the corresponding short line measure position;

Figure 2 is a view similar to Fig. 1 but shows the jaw stop device in operated position to automatically lock and retain the vise jaw that has partaken of quadding movement exactly at a selected short line measure position;

Fig. 3 is a vertical section taken on the line 33 in Fig, 1, showing the mold disk which cooperates with the vise jaws;

Fig. 4 is a detail perspective. View of a portion of the adjustable quadding control means;

Fig. 5 is a top plan view of the vise, showing the adjustable quadding control means according to the present invention applied thereto;

Fig. 6 is a rear elevation of a portion of the vise, showing the jaw stop device and control means according to the present invention in their normal relation before a matrix line is presented between the jaws; and

Fig. 7 is a view similar to Fig. 6 but shows the quadding control means in position to permit the jaw stop device to retain the jaw or jaws in closed quadding positions against lines which do not contain space bands.

Similar parts are designated by the same reference characters in the different figures.

In the accompanying drawings, i represents the usual vise frame in which the right hand and left hand vise jaws 2 and 3 respectively are mounted slidably for movement toward and from one another, the jaws being provided with suitable actuating mechanism such for example as that shown in Patent No. 1,970,527 hereinbefore referred to. Such mechanism, as shown in the present instance, comprises a jaw closing lever l connected to a rack bar which is provided with means such as a bolt 6 and lever 5 for connecting and disconnecting it with respect to the right hand jaw 2, a rack bar 5 similar to the bar it connected to the left hand Vise jaw 3, and a coupling pinion 7 fixed to the lower end of a vertically movable and rotatable shaft 8. In using such a jaw closing mechanism, either or both vise jaws may be moved one toward the other by action, at the proper time, of the closing lever t, the right hand jaw 2 moving alone when the bar 5 is connected to it and the pinion l is disengaged therefrom and from the bar 5* connected to the left hand jaw, or the left hand jaw 3 moving alone when the bar 5 is disconnected from the right hand jaw 2 and the pinion 7 is engaged with both of the bars 5 and 5 and both jaws moving simultaneously toward one another when the bar 5 is connected to the right hand jaw 2 and the pinion 7 is connected to both bars 5 and It is to be understood that the left hand jaw 3, as usual, is adjustable so that it may be set at different full line measure positions, this being accomplished for example by means such as that shown in Patent No. 1,970,527 hereinbefore referred to and comprising a manually operative knob 3 The coupling between the jaw moving bars 5 and 5 and between the bar 5 and the jaw 2 may be altered by the manual setting of a knob 8 fixed to a shaft is which is mounted rotatably on and extends across the top of the vise frame. This shaft it, as shown in Fig. 5, is provided with suitable links iii for shifting the pinion 7 vertically to couple and uncouple it with respect to the rack bars 5 and 5 and a link l9 operatively connects the shaft it to the lever z'i and reciprocates the bolt 5 to connect or disconnect the bar 5 with respect to the jaw 2. A pointer H rotatable with the shaft iii and cooperative with an indicator plate it, indicates to the operator the particular coupled condition of the jaws, that is, whether the right hand or the left hand jaw alone will be moved inwardly, one relatively to the other, by the closing lever ii, or whether both jaws will move inwardly simultaneously. The construction and operation of the jaw moving mechanism shown and described is the same as that disclosed in the Sperry Patent No. 1,970,527 hereinbefore referred to, to which reference is made for a more detailed disclosure thereof, and since the jaw moving mechanism per se forms no part of the present invention, further iliustration and description thereof are deemed unnecessary.

The underside of the bar 5 is provided with serrations E3 to cooperate with a toothed pawl l4 which constitutes a jaw stop device for retaining the jaw or jaws in different closed or quadding positions, the pawl hi being pivoted at l5 on a vertically disposed lever IS the lower end of which is pivoted on the lower portion of the vise frame, as shown in Patent No. 1,970,527 hereinbefore referred to, and a spring i i acts on the pawl l4 to swing it upwardly about its pivot when released. In the present instance however, the pawl M is released by a dog I7 which is pinned or otherwise fixed to a shaft is mounted rotatably in a bracket iS fixed to the rear side of the vise frame, the shaft i8 also having a latch l9 pinned or otherwise fixed thereon, as shown and described in my prior application Serial No. 58,017 filed January 7, 1936. By this arrangement, upon the usual advance of the mold disk 29 towards the vise jaws after the latter have closed, contact of a mold on the disk with the dog I? will rock the shaft it and thereby trip the latch is out of engagement with a block 21 secured to the pawl 14.

In order to prevent engagement until the proper time between the pawl 54 when so released and the bar 5, a gravity pawl 22 is provided, this gravity pawl being pivoted on and carried by a pin l 22 fixed in and projecting from the rear side of the bar 5, the gravity pawl resting on a shoulder 23 on the pawl i4, and the gravity pawl 22 being formed at one end with a lug 22 which cooperates with an adjustable member 24. As shown in Fig. 7, there is sufficient play or space between the engaging faces of lug 22 and member 24, to always allow the pawl Ht, when released, to swing upwardly sufficiently to prevent latch 19, under the action of its return spring fil from recngagover the block 2i. Such reengagement, however, is provided for at the proper time, by the downward movement of the link mil of the vise jaw closing attachment it! provided on machines of this class, the stud N32 of said attachment enga ng the arm m3 of a latch W4 and the latter engaging a shoulder I05 on the pawl id, as shown and described in my prior application hereinbefore referred to. Upon retreat of the mold, after the cast has taken place, the latch is, under the influence of its spring E9 will reengage the block 25 on pawl [4, following the downward swing of the latter under the action of the latch led.

The cooperative relation between the member 2t and pawls l4 and 22 is the same, under certain conditions as that between certain elements shown in Patent No. 1,970,527 hereinbefore referred to, but according to the present invention and as distinguished from the arrangement disclosed in said patent, the lever it, normally held to the left by a spring le (Fig. 7) can be held so that its head 25 and cam surface 26 thereon lie either in or out of the path of a roller 27 carried on the usual vertically movable justification bar 28. The means provided in the present instance for thus controlling the position of the lever it comprises a cam 29 fixed to a shaft 32 which is pivoted on and extends forwardly through the lever it, this shaft having a handle or lever 33 fixed on its forward end and which provides means for manually adjusting the cam 29 to bring either its face 3% or its lobe 3% against a stationary block 35 fixed on the vise frame.

When the cam 2a is set to bring the lobe 39 thereon into engagement with the block 3|, as shown in 6, the head 25 will be located to the right and out of the path of vertical movement of the roller and when said cam is set to bring the face 30 thereon into engagement with the block 3| as shown in Fig. '7, the head 25 on the lever I6 will lie in the path of vertical movement of the roller 21.

The member 24, as shown in detail in Fig. 4, comprises a slide 34 suitably guided to reciprocate in a housing 35 secured, as by screws 36, to the top of the vise frame, this slide being adjustable longitudinally by a pinion 31 which engages rack teeth 38 on the slide 34, said pinion being journalled in the housing 35 and having a knob 39 connected thereto for rotating it. The member 24 is formed on one end of a bar 40 secured to a member 4| which connects it to the slide 34, and the latter carries a finger 42 arranged to cooperate with a scale 43 mounted on the top of the vise frame, this finger and scale indicating the adjusted position of the member 24. The member 24 constitutes in effect an adjustable control means for the jaw stop device or pawl I4, the adjusted position of this member in relation to the composed and the justified length of the matrix line between the closed jaws determining the quadding position at which the pawl I4 will cooperate with the jaw closing mechanism of which the bar 5 is a part, or preventing such cooperation in the case of full length matrix lines.

The operation of the mechanism hereinbefore described is as follows: In Fig. 7, the cam 29 which controls the position of the lever I6 is adjusted to set the head 25 on this lever in the path of upward movement of the roller 21 on the justification bar, and in Fig. 5, as indicated by the dot and dash lines, the finger 42 is set, for the sake of illustration, at zero position at the left hand end of the scale 43, the left hand end 43 of this scale having graduations designating four positions or adjustments for the control member 24.

When the cam 29 and finger 42 are set as just described, the cooperative relation between the control member 24 and the pawls I4 and 22 is substantially the same as that between similar parts in Patent No. 1,970,527 hereinbefore referred to. At any setting of the control member 24 within the range of movement thereof corresponding to the readings I, 2 and 3 in the sec tion 43 at the left hand end of the scale 43, the quadding mechanism will function normally, that is, it will allow normal full lines to justify to the full line length or measure for which the jaws are set, as in any ordinary machine of this class, and it will automatically quad out all short lines composed to random lengths as they happen to occur. Thus, as shown in Fig. '7, when the justification bar rises as usual, the roller 21 thereon will contact with the cam surface 26 and swing the lever I6 to the right in that figure. The pawl I4 pivoted on the lever I6 will also move to the right in said figure, and if the com.- posed line presented between the jaws is sufli eiently long to prevent the lug 22* on the pawl 22 from moving to the right in said figure and from beneath the control member 24, the pawl M will be held from swinging upwardly about its pivot to engage the serrations I3 on the bar 5, notwithstanding that the pawl I4 will be released by tripping of the latch I9, and the movable jaw or jaws may then move outwardly to their normal open position against the usual jaw stops during justification of the line, and the justified line will be of full line measure. However, if the composed line presented between the jaws is sufficiently short to allow the lug 22 to move to the right far enough to pass beneath the control member 24, the pawl I4 will then be free to swing upwardly and engage the serrations I3 on the bar 5. The upward movement of the roller 21, acting on the cam surface 26 when the latter is in the path of said roller, as shown in Fig. '7, will urge the pawl I4 to the right, and when the pawl I4 is engaged with the serrations on the bar 5, the latter will be urged toward the right in said figure and the jaw or jaws connected to said bar will be moved to closed positions. Assuming that the short matrix lines contain space bands, the expansion of such space hands by the upward stroke of the justification bar, will react on the jaw or jaws connected to the. closing bar 5 and urge the latter toward the left in Fig. '7. These opposite forces acting on the bar 5 will, of course, result in tight clamping of the matrix line between the aws.

As previously stated, the stop control member 24 is shown in Figs. 5 and '7 as adjusted to the zero position on the portion 43 of the scale, and when so adjusted it will be evident that whether normal full lines or short lines are presented between the jaws, the lug 22 on the pawl 22 will normally lie to the right of the control member 24, even before the jaws close, and it will thus allow the pawl I4, in every instance, to swing upwardly and engage the serrations on the bar 5 as soon as the latch I9 is tripped by the advance of a mold to casting position. Such zero setting of the control member 24 is used when a number of lines are to be cast which do not contain the Q usual expansible space bands. Should the control member 24 be adjusted to the I, 2 or 3 reading on the portion 43 of the scale, which readings preferably correspond to the printers em scale, it would occupy a position overlying the 6 justment of the control member 24, provided I such lines contain sufiicient space bands, will justify to the full line measure. On the other hand, any lines composed short of such measure by more than the amount indicated on the portion 43 of the scale will be ouadded out, due to engagement of the pawl I4 with the serrations on the bar 5, such engagement taking place due to the passing of the lug 22 from beneath or moving beyond the control member 24 during closing movement of the quadding jaw. The pawl I4 thus acts.-in effect, as a jaw stop cooperable with the jaw closing bar 5 to lock the movable jaw or jaws in different random quadding positions which such jaw or jaws may assume while the cam 29 is set in the'position shown in Fig. '7.

According to the present invention, the cooperation between the jaw stop device or pawl I4 and the jaw closing bar 5 is controlled so as to allow such cooperation to take place automatically not only at random quadding positions of the jaw or jawsbut also at different selected quadding positions thereof corresponding to definite short line measures, whenever such action of 1 vided with graduated readings from 1 to ems,

and the slide which carries the stop control member 24, is set with its indicator finger 42 at the 12 em reading, as indicated by the full lines in that figure. Such setting of the control member 24 is shown in Figs. 1, 2 and 6, and in these figures the cam 29 is shown set so that its lobe Sll rests against the stationary block 3| on the vise frame I. With the parts so adjusted, when the justification bar 28 rises, as usual, to justify a line between the jaws, the roller 2'! will clear or not engage the head on the lever 16. Assuming that a short matrix line M has been presented between the jaws, the jaw closing bar 5 will move to the right in these figures, and if the line has been composed to a length sufficiently close to the selected 12 em length, the lug 22 on the pawl 22 will assume a position beneath the stop control member 24 during the jaw closing movement of the bar 5, so that notwithstanding tripping of the latch H! to release the pawl M, the latter will be prevented from swinging upwardly into engagement with the serrations on the bar 5 until interference therewith, by the control member 24,, is overcome. Since the jaw 2 which, in Fig. 1 has closed from the dot and dash line position to the full line position, is free to move outwardly or to the left in that figure under the expanding influence of the usual space bands in the line which serve L; to justify it, the bar 5, with the pawl 22 thereon,

will be carried to the left in this figure during justification, and as soon as the lug 22 passes the left hand edge of the control member 24, the pawl M will be free to swing upwardly and engage the serrations IS on the bar 5 when released by tripping of the latch 19, as shown in Fig. 2. The location of the left hand edge of the control member 24 corresponds to the selected reading on the em scale 43 and consequently engagement of the pawl M with the serrations it on the bar 5 will occur exactly at the desired quadding position of the jaw, that is, the pawl M, acting as a jaw stop for locating and retaining the jaw or jaws in different selected quadding positions, will be permitted to cooperate automatically with the jaw closing mechanism of which the bar 5 is a part, exactly at the 12 em short line measure position in the case of the setting just described, or the such other definite quadding position for which the control member fi l may be set. Since the cam 29 carried by the lever it is set with its lobe 30- against the relatively fixed block 3! on the vise frame when the device is adjusted for the quadding of short 1; lines to definite short line measures as shown in Figs. 1, 2 and 6, movement of the lever l6 and the pawl it carried by it will be prevented, and when the pawl M engages the serrations H3 in th bar 5, it will function as a stop which will definitely locate and retain the jaw or jaws in the selected quadding position corresponding to definite selected short line measure.

The horizontal extents of the engaging surfaces on the lug 22 and control member 24, it is to be understood, are such that lines to be quadded to a selected short line measure may be composed within variable amounts of the desired measure, it being seen for example in Fig. 1 that about one-half the extent of the lug 22 underlies the control member 24. One or two less matrices in the composed line may allow the lug 22 to underlie the full extent of the control member 24 or to underlie only a portion of the right hand end thereof, but in any event, assuming the presence oi a sufficient number of space bands in the line, justification thereof will move the bar 5 and lug 22 to the left sufiiciently far to clear the left hand edge of the control member 24, as shown in Fig. 2.

Should a line be presented between the jaws which contains space bands but is so short as to allow the lug 22 to pass to the right of the control member 2 when the jaw closes, or should the line be so long as to prevent the lug 22 from reaching the control member 24 when the jaw closes, the pawl M, when released by tripping of the latch is, will immediately swing upwardly into engagement with the serrations I3 on the bar 5. Such lines, when justified, will simply cast as ordinary quadded lines of random lengths, the space bands present in such lines assuring sufficient expansion thereof to take up the play between adjacent teeth on the pawl l4 and the bar 5. Obviously, lines which do not contain space bands can be cast only when the cam 25 is set with its face 3% against the block 3i, such adjustment of this cam allowing the roller 27! to engage the cam surface 26 on the lever It as hereinbefore explained whereby the pawl i l engaged with the bar 5 will exert closing action on the jaw or jaws to clamp such lines endwise.

The present invention thus provides an adjustable control means for governing the action of the jaw stop device for retaining the vise jaw or jaws in different quadding positions, such control means allowing the jaw stop to cooperate with the jaw closing mechanism automatically whenever lines are presented between the jaws which are too short to justify to definite full or short line measures and to thus retain the jaw or jaws at random closed or quadding position and, whenever required, allowing such cooperation of the jaw stop device with the jaw closing mechanism to take place only when the jaw or jaws occupy one or another selected quadding position corresponding to desired short line measures less than the full line measure for which the jaws are initially set.
