This invention relates to devices for use in making up type form pages and further relates to devices for clamping together the made up type form pages.

- In accordance with general practice in the printing art, Monotype or Linotype are set up by hand into forms representing a page or smaller unit on a working surface known in the trade as a galley. These galleys, which are in the nature 10 of a flat rectangular surface, are provided at certain of their adjoining edges with upturned flanges, against which upturned adjoining edges the type is built up into a longitudinally straightsided type form page. The operator, known in 18 thetrade as the make up man, builds the type groupup to approximately desired page length and then, by compressing the group longitudinally by hand and measuring with a rule, determines the error in exact length at opposite 20 sides of the group, such error usually being due to error in thickness of the individual type of the group, and then by insertion and/or removal offiller shims brings the type group to What hedetermines is the desired overall length and 25 squareness, and then ties the group up with twine or the like to be passed on and locked up with other type groups or forms for the printing operation. This system of manually compressing and measuring for length and trueness with a 50 rule is not only slow and tedious, but is not apt to be highly accurate, due to the fact that the compressibility of the complete unit is partially taken up by hand pressure which is not uniform and which often is not uniformly applied to opposite sides of the form. The result of such measuring of a type form for squareness and length under varying degrees of a poorly distributed pressure is that when the type forms thus made up are later passed through the lock-up process, where- 40 in they are subject to a relatively greater pressure and for which purpose they must be of true length and squareness, the lock-up operator is required to waste much time and energy in finishing the job of truing up the type form for 45 length and-squareness by further removal and/or insertion of shimsbetween type rows.

The present invention provides, in combination with a galley of improved form, a tool or device by means of which a built-up type form page may be quickly and easily subjected to equalized longitudinally exerted pressure for the purpose of measuring up for length and trueness, and in its preferred form includes an automatically operated meter for indicating the length and squareness of the built-up type page form, while subject to equalized pressure. In the preferred em bodiment of the invention this pressure produc ing and indicating apparatus is adjustably slidable longitudinally of the galleys and is readily shifted from inoperative position, wherein it in no way interferes with the building up of the type page form, to an operative position, wherein it is used to compress the type page form and check the length and trueness thereof, and wherein it also serves as a means for compressing the type and holding the same compressed while it is tied or clamped up.

Several important objects of the invention will be made apparent from the above and others thereof will be made apparent from the following specification and claims and the attached accompanying drawings, wherein like characters indicate like parts throughout the several views.

The galley, indicated as an entirety by In, is in the nature of a rectangular tray having a flat bottom working surface II and upstanding rails at its front end and two sides and being open at its rear end. The front upstanding rail .of the galley is indicated by E2, the right-hand upstanding rail of the galley is indicated by I3, and the left-hand upstanding rail is indicated by M. The front upstanding rail is undercut to provide an overhanging horizontal flange I5 and an underlying groove I6. The left-hand upstanding rail of the galley, indicated by M, is provided at its horizontal upper edge with an inwardly projecting flange that projects over and inwardly of the rail I4 in parallel relation thereto and is removably but securelyanchored thereto byscrews l8. Applied to the upper surface of this inwardly projecting flange I1 is a print-ers scale l9 calibrated in half-pica measurements. The pressure producing and indicating apparatus is all carried by a sliding casing-acting frame 20 that is slidable on the flat bottom ll of the galley and is guided for true longitudinal sliding movements by the longitudinal side rail M of the galley, to which said frame is slidably interlocked. In this respect it will be seen, by examination particularly of Fig. 5, that the upstanding front rail of the frame 20 projects under the inwardly projecting flange ll of the galley side rail I4; and by reference particularly to Figs. 1 and 5, it will be seen that the frame 20 is equipped with a cover plate 2| that is removably applied thereto by means of screws or the like 22, and is, at its lefthand edge portion, formed to afford a down turned flange 23 that works against the outside longitudinal surface of the galley rail 4, thus removably interlocking the frame 29 to the galley rail 4 for longitudinal sliding action and preventing removal thereof except by extreme longitudinal sliding action rearwardly beyond the end of the flange of the galley rail M, which flange, it will be noted, terminates considerably forward of the rear end of the galley but is, nevertheless, of sufficient length to maintain suitable interlocking engagement between the frame 2|] and the galley rail |4 throughout all of the operative positions of said frame 20. The front edge of the frame 20 extends in a plane exactly parallel to the front rail |2 of the galley and therefore intersects the plane of the galley side rail l4 at exactly a 90 angle.

Located directly forward of and extending in parallel relation to the front edge of the frame 29 is an extensible and retractable primary rail 24 that is carried by the frame 20 through the medium of push rods 25. These push rods 25 are securely and rigidly anchored to the rail 20 and work slidably through suitable apertures in the front and rear walls of the frame 29. Preferably the left-hand end of the primary rail 24 will slidably engage the inside edge of the galley rail I4 substantially as shown in the drawings. The push rods 25 are normally retracted to a position, wherein the primary rail 24 is against the front edge of the frame 20, by suitable compression springs 25 applied over the pushrods and confined between the front edge of the frame 29 and suitable collars 26 on said push rods.

The mechanism herein illustrated for extending the push rods and primary rail 24 against the action of said springs 25 compresses an operating handle 21 that is mounted fast on a vertically extended operating shaft 28, journaled in the frame 20, and its cover plate 2|, bell cranks 29, links 30 and a crank disc 3|. The handle 21 is made fast. on the shaft or spindle 28 by means of a suitable pin or the like 32 which permits removal of the handle. The crank-acting disc 3| may be made fast on the shaft by any suitable means such as a pin 33 and is formed at its periphery to afford suitable spaced stops 34 and 35 which cooperate with a spring 36 to resiliently retain the crank disc in either of its extreme positions. The bell cranks 29 are pivotally anchored to the frame 29 at 31, and the links 39 are each pivoted at one end to a bell crank 29 and at its other end to a diametrically opposite point on the crank disc 3|. The free outer ends of the bell cranks 29 work against the rear faces of the collars 26 so that under rotation of the handle and consequent rotation of the crank disc 3|, the push rods 25 and rail 24 may be projected from the position shown in Figs. 1 and 2 to the position shown in Fig. 3, in which latter position, it will be noted, the links 39 are in their dead center positions, wherein they are substantially capable of resisting retracting pressure of the springs 25 unaided. However, such tendency as may exist to automatically return the extended parts to their retracted position under the action of the springs 25 will further be resisted by the spring 36, which now resiliently engages the stop 34.

Longitudinally slidably interlocked to the front longitudinal edge of the extensible and retractable rail 24 by interlocking flange and channel engagement at 38, see particularly Fig. 6, is a bar 39, which bar 39 carries, through the medium of a stud pin 49, a similar bar 4|. The stud pin 40 is screw-threaded into the bar 4| and works in the bar 39 for free axial sliding movements and for free rocking movements in the plane of the bottom ll of the galley. The bar 4| is normally spaced from the bar 39, as shown in Figs. 1, 2 and 7 for example, and is limited against further movement away from the bar 39 by engagement of the head 42 of the stud pin 40 with a shoulder formed by reducing the pin-receiving bore through the bar 39 to provide a relatively narrow guide collar 43 for the pin 49. There is enough clearance between the collar 43 and the pin 40 to permit the above described rocking action of the bar 4| in respect to the bar 39, and, of course, there also must be suflicient clearance between the head 42 of the pin and the sides of the enlarged portion of the bore to permit of such rocking action.

Interposed between the

bars

39 and 4| near opposite sides thereof and at points equally spaced from the stud pin 49 is a pair of like compression springs 44 that maintain the

bars

39 and 4| normally spaced apart the maximum distance permitted by the head 42 of the stud pin. These springs 44 are seated at their opposite ends in opposed socket-forming recesses in the

opposed bars

39 and 4|. To prevent vertical wobbling of the bar 39 and any tendency of said bar 4| to rotate on its axis, the bar 39 is provided at its opposite ends with rearwardly extended guide tongues 45 that work slidably in slots or grooves 49 in the bar 4 As will be seen, particularly by reference to Fig. '7, there is suflicient clearance between the tongues 45 and the bottom of the grooves 46 to permit the desired free wobbling or oscillating action of the bar 4! with respect to the bar 39 in the direction of a plane of the base of the galley about the axis formed by engagement of the stud pin 49 with the shoulder 43 of the bar 39.

Slidably interlocked to the front side of the bar 4| by flange and channel engagement in the same manner as the bar 39 is slidably engaged by primary rail 24, is a secondary rail 41. This secondary rail 41 slidably engages the galley rail 4 and is preferably rounded at its galley-railengaging end to permit free pivot oscillation thereof with the bar 4 At their outer or righthand. ends the primary andpsecondary rails 24 and 41. are tied together for limited movements longitudinally} of the galley and for limitedoscillatory movements of the type described by a pair of overlapping links 48 and, the former of which is provided with screws or the like that work loosely in slot 5|v in the latter link. I These screwi-threaded'and slot-equipped

links

48 and 49 preventIlatei-al shifting of the'secondary rail 41' with respect to the primary rail 24 and prevent accidental displacement of the bars M and 39 byalongitudinal sliding action, but it 'is'important to note that there is suflicient clearance between'the heads of the screws 50 and the outer surface of the link 49 to permit the desired oscillatory action of the secondary rail 41 and itsimmediatelyassociatedbar 4|. I I 2 The primaryand secondary rails 24 and i? may hereinafter be. respectively referred to as primary and secondary pressure rails; and the bars 39 and, sincetogether they form a cross-head, may hereinafter be referred to collectively as a split crosshead;-? and singularly as the sections of a crosshead.

For adjustably limiting forward movements of the carriage-acting frame 20 there is provided an adjustable. stop device-52; I This stop. device 52 has longitudinal sliding lateraliinterlockingengagernent withfthe galley rail id, and is provided with a springpressed manually. retractable stop 7 pin 53' thatis projectable into any one of a long rail I4. The said'longitudinal sliding lateral interlocking engagement between the stop device E'Z and galley rail I4 is afforded by engagement of an L-shaped keeper lug 55 that works sli'dably inan' L-shaped groovewayllo extending longitudinally of the galley rail l4 and formed partially therein and completed by the rigidly'but removably secured horizontalflange |l=thereof. The

stop device 521s engaged by the down-turned portion ofthe carriage frame coverplate iii to limit forward movements of the latter and is pro vid'd atiitsupper surface with an inwardly p'rojecting pointer 51 that works over the surface of the scale l9 and co-operates with said scale to indicate the proper'position for setting. the stop for any desired type-form-page; length. Sincethe scale I9 is calibrated in pica measurements, the stop pin-receiving apertures in the galley rail|4 are 'spaced one pica apart. In use the sliding stop device 52 is adjusted vertically with the-stop pin retracted until the pointer 57 is opposite thescale calibration, indicating the desired type-page length and then is locked in that position by releasing the stop pin 53 and per mitting'the same to project into an alinedaperture in the galley rail I4. For purposes hereinafter made clear, the stop device 52 is provided with a spring retracted push pin 58 that is so positioned 'withgrespect to the lock pin 53 that it part of a" laterally shiftable indicating device,

by means of Which 'the truenessorerror in over series of pin-receiving apertures 54 in the galley all type form'length and squarenessmay' be readily detected by the operator. To complete this indicator a dial plate 63 issecured to the bar 3?: by screws or the like64 and slidably overlaps the upper face of the bar 4|; and co-operating with horizontal calibrations on this dial plate are opposed like pointers 65, each of which are pivoted at their ends to an opposite end portion of the bar 39 at E6, and each of which pointers as is intermediately pivotally connected by means automatic lock mechanism 68 consists of pivoted latch arm 69- carrying at its free end, pins Ill for engagement with apertures 54 of the galley rail Hi, a slide ll that is operatively coupled toand moved with one of the push rods 25, and a link l2 operatively coupling the latch arm 69 and slide H. The latch arm 69 is pivotally anchored to the bottom of the carriage-acting frame 28 at 13 and is provided near its free end with a cam surface Hi that is engaged by a rounded type end of the slide ll to move the lock pins into operative engagement with the perforations in the galley rail l4.v The slide 7| is held against lateral move-' ments and guided for true longitudinalsliding movements by projecting stops l5 and i6, and its operative engagement with the adjacent push rods 25 is affected by engagement of spaced lugs Ti lZ is piyotally anchored to the latch armJiQ and,

is loosely coupled to the slide 1| by slot and pin connection at 'lfl so that under final retracting movements of the slide, the link 12 will be brought into action towithdraw the latch arm and its pins ill from a locked position to a normal or inoperative position.

As a means for automatically taking up any slack Which may exist between the galley rail I4 and the engaged carriage-acting frame 20 and its cover plate 2| and thereby positively maine taining the said carriage-acting frame Zllelnd primary rail 2l against wobbling action and in predetermined square, with respect to the galley under pressure, theslide H is provided with a rearwardly extending portion 3?! that works slidably through the rear flange of the carriage frame 26 and against the inner face of the galley rail l4, and wlrn'ch is provided with a wedge-acting cam surface 8| for co-operating with the similarly shaped cam surface 32*011 the rear flange ofthe frame 23. Under extension of the push rods 25, primary rail 24 and slide H, the wedge-acting 7 Cam surface 8| is brought into tight wedging engagementwith its co-operatingcam surface 32, and'this wedge-acting engagement takes up any slack which may exist, and a certain amount of which slack is essential in order to permit free sliding action of the carriage-acting frame, and holds the carriage-acting frame against twisting action when put under pressure.

As previously indicated, this invention further provides novel devices for tying up built and trued-up type page forms in a transportable unit, and these devices are in the nature of spring clips 83 which may be applied directly to the type or used in connection with co-operating Monotype slugs 84, as conditions or results may demand. The spring clips 83 are preferably formed from flat bands of spring steel and are provided at opposite ends with inturned, preferably reversely curved tongues 85. The spring clips 83 will be made up in various different lengths for use in connection with type page forms of different lengths, and the tongues 85 thereof may be forced over the outer edges of opposite ends of a type form page, being applied directly to the end type so as to keep the assembled type tightly pressed together, or, if the type page form is made up of Monotype or a plurality of columns of Linotype, then the Monotype slugs, cut to lengths equaling that of the type page form, will be applied across opposite ends of the type page form, and the tongues 85 of the retaining clips applied to the ends of the Monotype slugs. The Monotype slugs, as is well known, are provided with longitudinal channels 86. The tongues 85 of the spring clips are preferably reduced in width by equal or slightly less than the width of the bottom of these Monotype grooves or channels 86, and the tongues 85 are preferably applied in the grooves of the Monotype slugs, as illustrated in the drawings. In this connection it is important to note that the channels in the Monotype slugs are of greater depth than that of the reversely curved spring clip tongues.

In the absence of the above described special galleyand toolcombination, these clips may be advantageously employed to quickly tie-up type page forms built and measured up in accordance with the old practice, in which case the type would be compressed by hand while the spring clips were snapped over the ends of the form, but, as will hereinafter be seen, these clip devices are very advantageously used in connection with the heretofore described galley and tool.

The type form pages illustrated in the drawings each comprise two longitudinally extended columns of Linotype, each type row or line being indicated by 81 and are bound together by Monotype slugs 84 applied across the ends of the double column of type and maintained under tension to compress the type therebetween by means of a pair of the spring retaining clips 83. This manner of tying up the type page forms is not only much faster than is tying up with twine, as is conventional practice today, but has the further advantage that the clips and slugs need not be removed for the lock-up process and printing operations but may be left applied to the type during these operations so that they may be removed from the printing-press frame later and stored away in a unit without requiring untying at the time that they are locked up and retying after the printing operation. Due to the normal clearance existing between the ends of the clips 83 and the extreme outer surfaces of the Monotype slugs, the type page forms thus bound up can be subjected to substantially any degree of longitudinal pressure in the lock-up process without causing or tending to cause buckling of the spring clips. Of course, if the spring clips are to be passed through the lock-up printing process, the lock-up operator must know and make allowance for the thickness of the spring clips, which will be a definite known measurement.

For use of the improved galley and co-operating tool, in connection with the spring tie clips, the forward end portion of the galley rail I4 is provided with a tapered surface 88 that terminates at the innermost edge of the galley rail l2. At the point of junction of this tapering portion of the galley rail M with the galley rail l2, the galley rail I4 is of a thickness just enough less than the width of the galley rail flange I! to allow for the thickness of a spring clip 83 being interposed between the thickest portion of said galley rail and the type lined up against the inner edge of the flange l1. Applied in the channel of the galley rail I2, normally having its free end pressed against the end of the tapered portion 88 of the galley rail I 4, is a leaf spring that is securely anchored to the galley rail l2 by a rivet 90. 7

Operation The operation of the entire apparatus, including the spring clips, will now be described.

If it is desired, as in accordance with the present example, to build up a type form page consisting of two columns of Linotype, a Monotype slug 84 is first placed in the lower left-hand corner of the galley with its channeled side against the galley rail l2 and its left-hand edge against the flange I! of the galley rail l2, with a spring clip 83 positioned as, for example, in Figs. 2 or 3, wherein the main body of the clip underlies the flange H and the tongue thereof, at its forward end, is interposed in the channel 86 of the applied Monotype slug 84. In this position the spring 89 maintains the forward tongue of the spring clip 83 in engagement with the base of the Monotype slug channel.

During the process ofbuilding up the type page form to its approximate dimensions, the carriage-acting frame and its associated parts, which are carried thereby, are slid back toward the rear of the galley where they are entirely out of the way. However, before starting the make-up process, the adjustable stop 52 will be set so that its pointer 51 registers with the calibration of scale l9 indicating the desired page length plus the thickness of the Monotype slugs 84 when such are used. Hence, if it is desired to build up a type form page which is 29 picas in length, the pointer 51 should be set at 31 pica calibration so as to allow for the thickness of two Monotype slugs, each of which have a thickness of one pica.

With one Monotype slug and clip 83 positioned as above described, the column or columns of type are built up to the approximate desired page length, and then a Monotype slug 84 is applied across the rear end of the type form page, as indicated in the drawings. The column of type adjacent the flange I! of the galley is built up in contact with the inner edge of said flange, and the light pressure exerted by the lower type of column-against the lower inner end portion of the first applied spring clip 83 tends to force the upper end of said clip back against the inner face of the galley rail l4 so that the upper tongue thereof is automatically maintained out of the way during the build-up process.

r the instrument.

above the zero line. longer or shorter than the other, this condition Now to make a quick check .of the overall length and squareness of the build-up type form page, the operator will, by forwardly pressing on the handle 21, draw the carriage-acting frame 20 forwardly against the stop device 52, after which he will rotate the handle 21 approximately 180 in a clockwise direction, thereby extending the push rods 25and primary rail 24 from their inner extreme positions, shown in Figs. 1 and 2, to their maximum extended positions, shown in Fig. 3, in which latter position they will remain locked against accidental withdrawal. The distance of extension of the primary rail 24 is greater than the distance between the approximately sized type page form and the secondary rail, and therefore the secondary rail ll will bebrought into contact withthe rear end of the type page form'before the primary rail as has reached its extreme extended position, with the result that further extension of the rail from this point results in compression of the springs 44, which,=acting through the bar ii and secondary rail 41, will place the type under pressure. It should here be stated, however, that the complete unit, consisting of bars 39 and M and elements carried thereby, islaterally shifted so that it is inline with the transverse center of the type page form before this pressure operation is started; For the purpose of this centering of the transversely adjustable pressure and measuring unit, there is provided a center mark 9! on the cover plate'92 -of this unit, which cover plate, incidentally, is anchored to the bar 39 by screws 93, overlaps the bar 4! and is provided with a sight opening 94."

The continued forward movement of. the primary rail24 and bar 39 after the secondary rail 41 and bar 4! have come to a stop, against the action of the springs 44, causes an upward movement of the free ends of the pointers 65 over the (ac-operating scale 63; and if the type page form is of the desired length and squareness, this will be indicatedby the position of both pointers over the navy center scale calibration .of the indicator,

indicated by zero. If the page be too short but square, the pointers will indicate this'position and the extent thereof. If the page be too long but square, this condition and the extent thereof will be indicated by a position of the pointers If, either column of type is will be indicated by the pointer on that side of In this way the operator can quickly determine the error in length or squareness, and then, by quick counter-clockwise turn of the handle 27, can release the type" unit from pressure and insert or remove shims from between the type to compensate for the error, and

then by another quick turn of the handle, he

can get a re-check on the trueness of the form. This process can, of course, be repeated until the desired degree of accuracy can be returned, and such indications of true size and squareness as are read on the indicator are taken under sufficient pressure and under evenly distributed pressure, so that the type page unit will also measure up true when subject to relatively great pressure exerted thereon during the lock-up process.

When the type page'unit is iinallyisquared up, the spring clips 83 are applied while the type is still subject to, pressure. The front end of the left-hand clip, being already applied at its forupper end of the left-hand spring clip 83 with nel in the Monotype slug 84.. This done, the

right-hand clip 83 is pressed on manually, and with a type held under relatively great pressure, it is not difficult to spring the tongues of the clip over the edges of the slug. The type form page unit can now be released from pressure and transported to the lock-upframe.

In the measuring up of the length'and trueness of either a single or double column group of type, the indicator is placed in thetransverse center or the type unit, but if more than two, three. for example,'columns of type are to besquared up by means of the instrument, two columns should first be built up and squared up in the manner described, and then the third column should be built up. and squared to the previously built-up two columns by moving the indicator mechanism to center between thetwo previously built-up and last built-up'column. The front face of the secondary rail 47 is channelled'in the same manner as the galley rail I2 so as to receive the tongues of the spring clips when said spring clips are applied directly to the end type of the group.
