TY29E-:BARy OB CASTING-SLUG.

Specification of Letters Patent.

Patented Sept. 25, 191:7.

Original application ledMay 24, 1911, Serial No. 629,099. Divided and this application led July 3, 1914.

. Serial No. 848,764.

'Slugs, ot which the following is a specification, the principle of the invention being herein explained and the best inode in which l have contemplated applying that principle, so as to distingui sh it fromother inventions.

rlhe present improved type bar or casting slug is shown and described in my (io-pending application for typograph mechanism liled May 24, 191]., Serial No. 629,099 out of which the present case has been required to be divided. While the aforesaid typograph mechanism, which is or' necessity shown and vdescribed inthe present specification also, is adapted for the making of type bars or slugs of the kind in question, it will be understood that yother mechanism suitable for the purpose may be devised, no limitation being implied to the production of such bars or slugs by any particular typograph mech anisin. v

tsliould furthermore be noted that the method of making type-bars or slugs eXempliiied in the operation of the aforesaid mechanism, and resulting in the production of the aforesaid bars or slugs, il'orms the subject matter of a separate divisional applicaby inc March l, 1917, Serial No. 151,715.

As will be readily understood, larger type than are found on the matrix bars regularly used on typographs are very frequently desired for printing",` headlines and advertise ments, and the object of the mechanism herein described is to do away with the necessity lor maintaining :i stock of sorts in order that'the printer may be able to sct up a form with such larger type, since with such mecha nism 'including a single font ol' matrices of such larger type, any amount oi large type iruiltcr may be sot up.

l, am aware that it has l'icrctoi'ore been .sought to cast slugs vwith initial letters larger than the in;` the matrix oi the larger letter or other character to ovrrdap the front face ot' the inolfl. The slug;` thus 'formed will have a thin over-lapping body oi metal bearing body lucc by simply allow-v such larger character' on its Iace, which overelapping -portion is adapted to extend over the face of an adjacent smooth slug. Although suoli extended character maybe thus supported from bclow, it is nevertheless so thin that it has a tendency to curl, especially on cylinder presses and when subject to hard usage, One object of the present invention, accordingly, is the avoidance of the difficulty just noted, by providing a slug; fully as strong and durable as the original one, of .uniform thickness throughout. A further object of the inventionis to produce slugs by Imeans of which a line of large type of greater length than the normal width of a column may beset up without any breaks occurring between successive slugs. To the accomplishment. of 'this and related ends, said 'i invention, then, consists' ofthe means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain meehanisni embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be' used'.v

Inbsaid annexed drawing/'2* Figure l is a transverse section through 'a mold and the adjacent parts oit' a typograph adapted to produce lmy improved typeibar or .casting slug; Fig. 2 isv a perspective view of animproved matrix bar that forms a feature ot'such mechanism; Fig. 3 is a similar viewfot' a blank matrixbar for use in conjunction with the foregoing; Fig. 4 is d per.-

spcctive view of a slug, or line of type? cast' l with matrix bars of the kind Ajustrcerred to; Fig. 5 is a transverse sectional View of which a slug such as shown in Fig. 4L may lie cust; Fig. Sl is a Similar but broken lOIlgi- 'liulinal sectional View through the mold illustrating the manner in which a different I lorm of slug may be cast; andl Fig. 10 Illustrates several forms of slugs.

Asindicated .in the above brief description of the drawing', thc parts more immo diatoly ali'cctcd by the present improvemerit are the mold and matrix bars which coperate to form the slug or line of type. rlfhe form of mold 1 appearing in Fig. l is that employed in the .so-calledLudloW typograph and is shown in association with the supporting bed 2. The latter may be regarded simply as typical of any suitable support Whereon the matrix bars 3 are adapted to rest pending the approach'to the mold of the nozzle 4 of the eastingpot (not shown), from which molten metal 1s de: signed to be supplied to the mold from beneath. The usual terminal squirt plate 1 ployed in other onstruetions of typograph,

by being morel or less deeply recessed on their under faces and having the matrices (l, proper,l located at the bottoms of these recesses 7 (see Fig. 2). lThe recesses in question providefor the formation of a slug S with an upper overhanging portion 9 of correslnuuling dimensions, when a body of such' matrices areA assembled, as will be readily understood.

The manner in which the matrices are thus assembled and heldin place during the casting operation is a matter of Airuliferenee ;l a snnple frame 10, preferably of rectangular u-i`or1n, is shown, in the drawing, while a presser foot 1l is employed to clamp bars 8 ragainst the casting face of the mold. For

forming the spaces between words, as also for leaving blank'spaces at the ends of the line \\'heret|n\.ty}numtierdms not extend through to such endsl employ bars l2 of the form illustrated in Fig. Il. which dill'er from the above. descrilual` matrix bars 2l in that. the recesses ll formcdon their under t'aces are not so deep as recesses and of course do not bear matrices. Such recesses are, however, of a sullicient depth to' render continuous the overhanging or enlarged portion 9 of the slug, as will clearly appear from a reference to Fig. 4, in which a slug formed by hars of the kind herein described is shown in perspective. although theoverhung or head of the slug is obviously `not so tinck vertlcally at the space point lu question as `where clnn'aeters are found on this upper face.l

' (losure of the respective ends of the space above. the upper face ol" the mold 1 that is laterally inclosed by the walls of the reces-ses 7 or 13, as the case. may be, 1n the assembled bars, is ellected by means of blank baa's I4 (see Fig. S), or equivalent members.

'llie object in reducing the thickness of .below the base line of the relief base or the head 9 at space points in the fashion just described'and illustrated .in aforesaid Fig. 4, is to avoid contact between the so called quad line and the sheet; being printed, when the type bar is in use, for such contact will, of course, tend to smudge or smear the impression. In other words, such quad line lies with its front edge below the base line ofthe printingr characters, that is pedestal.

lly the mechanism just described I am enabled to-'cast slugs or lines of type having enlarged upper portions with p actically the same facility that ordinary slugs arevcast in the regular operation of the typograph. As will be obvious, the slugs formed in this fashionv will excel in durability, as well as in the clearness of the impression whichc they are capable of giving, by reason of the solid support' all'orded the characters on their faces. lt has already been indicated that the casting mechanism. may be variously arranged, while still maintaining the. adrantageous features of the in'iproved matrix bar construction constituting fue present invention. There is, in other words, no intention` by referring. as above, to a particular typograph, to`imply a limitation in the adaptability ol the mechanism; and it should 'further be borne in mind that such .improved bars may be supported directly on the mold face under certain conditions, inasmuch as in the actual casting operation the bars are in etl'eet simply clamped between such face and the. under side 'of the presser fool', or equivalent clamp member.

instead ot' positioning the assembled body ol matrix bars symmetrical-ly over the slot in the mold` as is illustrated in Fig. 1, such bars, together with their holder,may be yshifted to one side or the other as shown in Fig. (i. ln this way the form of the, slug made t'rom the composite matrix .so provided is changed from that of Fig. 5 to that of Fig. 7. 'lhe offsetting ef the enlarged,

`type-hearing portions of-the slugs thus obtained may be found desirable under certain conditions, and 'it is entirely feasible to thus form said slugs owing t'o the relativelyr large volume of the portion in question, whereas tov attempt to do this by slightly overlapp'ng the simple matrix would be entirely i1npracticable, owing to the chilling of the thin body of ymeta-l provided for.

ltnrthermore, by using bars without; any recesses at all, the corresponding section of the slug will, of course. be reduced to simply the relatively narrow body portion. The use of such bars and the formation thereby o t' slugs reduced at one or both ends is oceasionally found desirable where a line of large type of greater length than the width .ot' a column is being sel up; for in such case 11:0

typograph mechanism under consideration.

Thus in the particular case under consideration, the upper, type-bearing portion of the iirst slug will be extended beyond the body of said slug by allowing the last bar, that carries the matrix yof the letter W in` the assumed instance, to overlap the face of 'the mold as shown in. Fig. 8, thus leaving the end of said slug of the form clearly illustrated at the left in Fig. 10. Due note is,'of course, taken of the length of the added or projecting portion of the slug, and .in as senibling the bars for the next slug, the first bar l5 is a blank ofa Width'eqiial t0 the extra space taken Aby such end matrix bar in forming the preceding composite matrix, (see Fig.4 9); cast, the enlarged portion 9 thereof Will terminate short of sich end a distance equal,v

as a result, when the slug is facti itl-is entirely permissible to utilize Wooden spacing material for this purpose, this being desirable inasmuch as the weight of the form is thereby considerably reduced.

Gther modes of applying the principle of my invention may be employed instead of the one explained, change being made as re gards the mechanism herein disclosed, provided the means stated by any of the follow ing claims or the equivalent oi such stated means be employed;

I therefore particularly point out and distinctly claim `as my invention l. A slug or ty pe-bar made from a co1nposite matrix having its upper, type-bearing portion project beyond one end of saidslug.

2. The combination oi two slugs or type bars made troni composite matrices and forming adjacent portions of a. continuous line of type,` the upper, type-bearing portion of one lslug terinii'uiting short ot the end of said slug adjacent to the other slug and such upper, type-bearing portion of the latter.

3. A yslug or type-bar made ironia composite matrix, said slug comprising a body to the projection onthe preceding slug, asr anwupper, enlarged portion bearing the-type fcharacters, such' enlarged portion being veriiiusaaa at the right ming. io. .Whem the two slugs are assembled, accordingly, a i

tically' less, thick at space points than Where continuons eil'ect is secured that would begicharacters are thus formed on its face.

otherwise impossible.

lt will be observed that in all the diiierent `forms of slug obtainable by the mechanisngil herein-before described, While the body ofA the slug remains of ordinary dimensions in length and Width, that is of the same dimensions as it-Would have Were it to bear type characters of regular size, Isuch body is of less than ordinary yheight bythe thickness of the enlarged, or overhanging,-portion 9. In this Way, the slug may be maintained of standard height, which in the U. S. is 0.918 inches, as is Well known. No addi-tional metal is obviously necessary in vcomposing a body 'of display matte-r with slugs thus formed, over what would be required in the 4case of an equal body ofordi'nary print.

lt will further be observed that by making thc'overlninging enlarged portion of the sliig oi substantially the saine v thickness vvertically as the body portion .is transversely, the use oi.' the supplemental blanks shown in lligs. 5 and 7 is not needed in order to sup- 'port such overhang, but merely to fill in between the sides of the slug bodies, so that the latter can be properly locked in the form. ln other words, in view of the fact othat this overl-1 an ging portion'in the present improved slug issulliciently thick vertically to render the saine substantially inflexible, it is not infrcssaiv that the intermediate blank supart-slugs should be of exactly the right height to accurately vsupport the overhang and thus the. printing face` ol the slug'. In

l' e. A slug or type-bar made from a com* posite matrix, said slug comprising a body ,portion of ordinaryA length and Width, and an upper, enlarged portion' bearing the type portion of ordinary length and Width, and

characters, such upper, enlarged portion terminating short of one end of said slug.

5. A slug or type-bar made from a composite matrix, said slug comprising a body Aportion of ordinary length and Width, and

an upper, enlarged portion bearing the typev characters,'such upper, enlarged portion projecting beyond one end of said slug.'

6. The combination of two slugs or typebars made from composite matrices and forming adjacent portions of a continuous line of type, each slugfcomprising a body portion of oidii/i/arydength and Width,'and an upper, enlarged portion bearing the type characters, such upper, enlarged portion of one slug terminating short of the end of said slug adjacent to the other slug and such upper, enlarged portion of the latter projecting a corresponding amount.

an upper, enlarged portion bearing the type characters and laterally overhanging said body portion, such upper portion being Sulliiently thick vertically-'to render substan. tially inflexible the part thereof thus overhanging. Y

8. A slug or type-bar comprising a body portion of ordinary length and width, and an upper, enlarged portion bearing the type characters and laterally overhanging said body portion, such upper portion being of substantially the saniethickness vertically as said body portion is transversely.

9. A slug or type-bar comprising a body portion of ordinary length and width, and an upper, enlarged portion bearing the type characters and laterally 4overhanging said body portion, such upper portion being Sulliciently thick vertically to render substantially inflexible the part thereof thus overhanging, and being less thick at space points than where characters are thus formed on its face.

10. A slug or type-bar comprising a body portion ot ordinary length and width, and an upper, enlarged portion, bearing the type characters and laterally overhanging said body portion, such upper portion being:r of

substantially the same as said body portion is transversely, and being:r less thick at space points than Where characters are thus formed on its face.

11. A linotype slug of the character designated formed with type hifh surface printing characters, said printing, characters being supported on a pedestal, with the quad line front edge vbelow the base line of said printing characters and below the base line of the pedestal so as to prevent the contact of said quad line edge with ink roller or surface to be printed upon, as set forth.
