Y The cross members serve as ties for the less ie provision of slugs which are less than type high slugs and the less than type t high with retention lmeans for high slugs serve. as ties for the eross mem- ,G0

i securing them to the dram, flat base plate or bers. Where it is desired to printpgen'erally grooves have been provided in vertical lines for columns or tabular work, the cross members of the present invention are preferably in the form of printing rules disposed generally circumferentially of the drum, or, where the carrier is in the form of a fiat base member or plate, these cross members are disposed over the surface of this flat plate across the direction of extension of the slugs and, in either case, are provided with raised printing rules or edges for printing the vertical lines. ln this case, the unitary character of the less than type high slugs will maintain the desired relative positions of the cross members, not only when the cross members are in place upon the carrier, but will maint-ain that positioning upon removal of the assembled slug and cross member unit from the carrier so that this unit may be relaced without again effecting the desired relationship of the slugs and cross members. According to the present invention, the less than type high slugs are, preferably, grooved generally transversely across the tops of the slugs. am aware that cross b the upper ends of type high slugs and that tie members have been secured therein, but these provisions have been in connection with type high slugs for tabular work and the cross grooves have been confined to the raised printing rules upon the upper ends of the slugs. That is, the lower ends of the grooves have terminated at the base of the printing rule projection and the cross members have, therefore, seated directly upon the upper ends of the slugs with the result that there is not a true base for the cross members and these cross members will not be true if there is any variation in the heights of the slugs or any irregularity in the upper surfaces thereof. ln the present invention the cross grooves extend through the depths of the upper lianged heads of the slugs. Vhen the slugs are positioned upon the carrier, the inner or lower ends of the `grooves preferably extend inwardly to or inwardly beyond the surface of the carrier so that the cross members, upon ins-ertion through these grooves, will rest and find support not upon the slugs themselves, but upon the outer surface of the drum or flat base plate. hWhere the slugs are provided with printing rules, and assuming desired to print lines or other matter that it is with the cross members, the grooves extend through the rule projections on the slugs so that the line printing edges upon the cross members may extend out to the printing edges of the rule projections on the slnefs.

/Vhile the grooves and cross members are illustrated as of generally V-shaped formation with the apices presented outwardly, it is to be understood that other equivalent formations are contemplated within the scope of the present invention.

With the present invention, it is unnecessary to block up a solid mass of slugs in the manner required with the type high slugs and cross rules as previously provided. l believe that it is broadly new to interlock either a rule or binder with the slugs and to support the rule or binder upon the drum, flat base plate or other carrier for the slugs.

So far as this aspect of the invention is concerned, it is immaterial whether the surface of the carrier is circular, as in a drum type printing machine, or flat for use on standard flat bed presses. The supporting of the rules or binders which extend across the slugs upon the carrier avoids any objectionable results where there are variations or inequalities in the slugs and, at the same time, the slugs may be spaced apart with relatively wide gaps therebetween. Unless, of course, it is desired to fill in the spaces with rules or other printin material, there need be only a few slugs at spaced 'ntervals for binding the cross members together. The present invention enables disposing printing characters on the slugs up close to the rules or binders which extend across the slugs. The bases of the rules or cross binders may be just as wide, or even wider, than heretofore, but, due to the extension of these bases down through the flanged heads of the slugs, the width of the rules or binders at the outer printing surfaces of the slugs may be less and the letters or other printing matter upon the slugs may therefore be brought up closer to the rules or binders.

Refering to the drawings, and par icularly to Figs. l to 7,' 5 designates the, drum or carrier, such as comprises partof a .multigraph or other These drums 5-are usually composed of drum segments which are usually heldtogether .by spring clips lor other suitable connecting means, The drum 5 has spaced parallel rails 6 extending longitudinally thereof with the under-cut channels 7 .forzreceivingand engaging thebase flangesnS -of-thetype lines or yslugs 9. The drums'hown is ofthe usual known character and is merely illustrative in the present disclosure. l y

For purposes of illustrationt ,l have selected the less than' type high slugsof my prior patents above referred toxffor disclosure herein. As illustrated in `ig, 8,*these slugs have the upper flanged heads 3h0 with the base flanges or base portions 8\integrally connected therewith through-the connecting necks ll. i y

The height it :(Fig., 8) ofthe slugs 9*'is less than type high as'that expression is understood in the art. The .outer face of the head l() carries the printing means, which printing means may be in the form of in# tegral outwardly tapered vand relatively sharp edged printing' rules l2 (Fig.8). In-

a llat base plate for use ona flatbed stead of printing rules 12,`V the heads l0 of the slugs 9 may carry printing' characters the form of letters as indicated atlld inF ig. l, or figures as indica-ted at in" the liguria, or any other printing charactersor symbols or combination thereof. l

It is also contemplated within the present intention to omit the printing meansentirely from the Vslugs and to use slugs .of ,ntegralline formation for .even individual .blocks lfor interlocking with rule. stripsembodjying the present invention. u y

The longitudi grooves or nicks 16 form-ed in the .opposite sides 4 of the slugs V9 `interloch 6, as shown inV Fig. '2, 3 and `grooves through the depths of the upper flanged head `of the groovesy 20. ln rotary printing machine.

Vreference to the copy.,

withv the outer headedA endsy 17 of the f drum rails Fig, yandhold the slugs .9 in place upon the end and in the form of unitary printing lines.

These slugs @are provided with aligned extending across the slugsl and l0.. When the slugs are positioned upon the carrier, the inner or lower ends 20 preferably extend inwardly to or 1n- Vwardly beyond the surface of the carrier as indicated in dotted lines at 2l in Figs. 3 and 4; so that the cross members or binder elements 22 will rest and find support upon the surfaceof the carrier.

The binder or tie strips 22 have flat bases for seating upon the outer surface of the carrier and the portions of these strips 22 with` in the height of the head l0 of `the slug are lof a cross sectionconforming with the shape the illustrated embodiments of the invention, the sides of these grooves are tapered Vwith the grooves converging outwardly so as to interlock with the corresponding section of the strips'22. The strips 22 are preferably of. brass, al= :though this may vary,

of the groovesf the binder element-s 22' are disposed generally xcireuniferentially ofthe drum and are curved to conform` with the surface of the shown in. Figs. 2 and 7, but, .of course, where the slugs are used with a llat base plate Aor carrier, for use upon aA fiatv bed press, this curvature of the strips 22 may be omitted and the straight strips will `seat upon the outer flat .surface of the carrier as shown in Fig.l 12.

llVhe-re the binder elements 22 areV adapted for printinglines generally vertically vwith theirouter edges l are relatively'sharp edged printing' rules w'. ich extend lfrom the outer surfaces of the heads l() for printing cooperation with the paper `or other material. The binder strips 22 .are adapted to Vbeinsertedfendyvise through the aligned grooves 2.0 in the slugs :9 .and1A are held against displacement outwardly from the carrier by the ,outwardly converging formation of the grooves `andthe corresponding section of the binder elements. Other 'equi-vaient binder elements and groove formations -ufhich vwi'llfhold the parts together in equivalent manner are contemplated within the ldrum as "present invention. The binder elements 22 From the foregoing\',` it will now be apparent that the binder strips 22 tiesor bind the.

printing lines or slugs 9 together to form a unitary printing plate or combinationwhich isadapted for mounting as a unit upon the carrier by the simple expedient of engaging the retention means in the slugs 9 with the cooperating retention means in or on the carrier and sliding the unit into place longitu- :linally of the retention means. When the printing assembly is in place, the bases of the binder strips 22 seat upon the outer rail surfaces of the carrier so that the seating of these binder strips is independent of varia tions or irregularities in the slugs and, at the same time, the necessity for blocking up a solid mass of slugs is avoided.

In Fig. 1() a portion of a slug and binder strip assembly embodying the present invention is shown removed from the drum. Obviously, the binder strips 22 retain the desired assembly of the slugs 9 and the entire unit is adapted for replacement upon the carrier as a unit at any time and Without again assembling the slugs or individually securing them to the carrier in the desired relationship. Relatively Wide spaces are shown between the slugs 9, such as obtained by skipping spaces between the slugs as shown in Fig. 't' and, at the same time, the engagement of the binder strips 22 in the slug grooves 2O holds the slugs in proper relation. The relatively tight [it of the strips 22 in the slugs will hold the slugs in substantially any desired spaced relation, but even if there is some slipping of the slugs along these strips, that Vis not objectionable, because the slugs are all held in assembled relation and may be conveniently slipped along the strips 22 for insertion into the desired chases of the drum or flat plate carrier.

At the same time with the unitary type line or rule formation of the printing slugs as distinguished from the individual printing characters or printing blocks or blank blocks, the desired relative positions of a number of printing rules 22 may be maintained relative to the slugs 9 and relative to each other upon removal of the assembled unit from the carrier, so that when this unit is replaced the desired rule relationship will be provided Without again effecting it.

Integral slug lines 3() may be inserted into the chases of the carrier adjacent the ends of the printing units as shown in Fig. 1 for holding the rule or tie strips 22 against displacement in a direction longitudinally of said strips. The slugs 30 may have printing characters or printing rules or other symbols or combination thereof, or these slugs 3() may be blank slugs for the sole purpose of providing stops at the ends of the printing assembly to prevent endWise displacement of the strips 22.

In Figs. 1, 2, 3 and 5, the slugs 9 are placed adjacent eachother in adjacent chases of the carrier and some of the slugs 9 have printing rules, While others have printing characters.

ln Figs. 6 and 7 the assembly is substantially the same as Figs. 1 and 2, but in this ycase the slugs y40, instead of being placed adjacent each other in adjacent chases of the carrier, are spaced apart so that there will be empty chases between the spaced slugs 40. rFliese slugs 40 may, as before, be blank slugs for holding the strips 42, or they may have printing rules or type or other printing characters thereon, asdesired.

The strips 42 may have printing rules 42 or these printing rules may be omitted, as before, in Which case the strips 42 Will serve as binder strips only for the slugs 40.

Where the slugs 9 are provided with printing rules 12 in Figs. 1 to 5 and 8, or Where the slugs 40 are provided With printing rules 40 in Figs. 6, 7 and 10, the grooves 2O (Fig. 8) continue through these rules at 20 and are of a formation conforming With the formation of the projecting rules on the printing slugs.

In the embodiment of Fig. 11, the slugs 45 are provided With printing characters shown in the form of type letters, although this may vary, and in this case the strips 4S serve as tie strips as in the previous embodi ments and seat upon the rail surfaces of the carrier, as before. In this case, the outer edges of the strips 48 are not provided with projecting printing rules, but terminate in- Wardly of the printing line so that they will not engage the paper or other material with which the printing line cooperates, nor perform any printing function, but Will serve merely as tie elements.

In the embodiment of Fig. 12,1 b ave shown the invention in connection with a fiat base plate for use With flat bed presses. rEhis flat base plate is indicated at 50 and is provided with under-cut channels 51 corresponding With the channels 7 of Figs. 1 and 2. The slugs 52 are similar to the slugs of the previous embodiment and are mounted in the channels or chases 51 with their outer flanged heads 53 seating upon the outer surface of the carrier 50.

The strips 54 are applied in the same manner and -may be varied as pointed out in connection with the previous embodiment, the only difference being that the strips are, in this case, straight with their bases scating upon the outer surface of the carrier 50. They are interlocked with the slugs in the manner pointed out in connection with the previous embodiment and they may be provided with printing rules 54', or these printing rules 54 may be omitted. rThe slugs 52 are shown as spaced apart by skipping chases 51, and the slugs may be provided With printing rules 56, as shown, or with printing characters or the printing rules and printing characters may be omitted and the slugs 52 used merely for supporting and binding the rules 54 together. As before. the interlocking of the slugs 52 and strips 54 individual i rule 63 is applied 72 similar toithose' previously .stripV interlocking binds these elementsV into a unitary assembly wliichmay be conveniently removed and replaced as a unit and, at the same time`, the

assembly is flexible, in that the partsV are all separable and may be removed and replaced' with others.

In Fig. 13 I have provided for applying horizontal rules without skipping spaces between the slugs.

The' base 66 of the rule' 63 is preferably tlat and preferably seats upon the outer rail surface of the carrier when the assembled slugs 60 and strips 62 are applied thereto.

In' the embodiment of Fig. 14C Ihave provided short separate or individual grooved blocks 70 for'mountinginthe chases of the drum or inthe chases of the flat plate carrier in' the V manner of the typev slugs or type lines of the previous' embodiment. 'Iliese individual blocksy 70' are provided with grooves described for receiving and interlocking with the printing rule and=binder strips 74. In thisr case,I as before, the vgrooves 72 will preferably extend inwardly to orinward'ly beyond the suri'acel of the carrier so' that they strips 7e will rest and find. supportupon the surface of the carrier `orfthe outer rail surface thereof.'V TheV .grooved blocks 7 Of in this caseV are preferably hlank blocks for the sole purpose of holdingI the rule strips 74", but these blocks TOfmight `be provided with printing characters'if desired; ,l

As shownin Fig. l, the chases between the drum rails Gniay be closed at one endY of the drumV by a circumferentially Y `extending flange or'endv ring 80. Thisend ring maybe of the'usua'l known character, and it is to be rn'derstoody that in a flat plate vcarrier the ends of the chases may be closed, as desired.
