Application filed May 24, 1911. Serial No. 629,099.

To all 'whom t may concern:

Be it known that I, lVlLLLiu A. READE, a citizen of theUnited States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Typograph Mechanism, of which the following is aV specification, the principle of the invention heilig herein exlained and the best mode in which I have contemplated applying that principle, So as to distinguish it from other inventions.

, ln my co-pending application, filed Feb. 27, 1911, Serial No. 611,246, I have described a form of mold for ilse in typographs, or similar machines for casting lines of type, whereby such lines of type are formed to accommodate larger type than are found o n the matrix bars regularly used. Such larger type, as will be readily understood, are very frequently desired for printing head lines and advertisements, angd by 'this adaptation of the typograph, the necessity for maintaining a4 stock of sorts in order that the I printer may be able to set up a form with such larger type, is done away with, silice. with a single font of matrices of such larger type, any amount of large type matter may be set. up.` I am aware that it has heretofore been sought to cast slu s with initial letters larger than the body ace by simply allowing the matrix 'ofthe larger letter, or other character, to overlap the front face of the mold. The slug thus formed will have a thin overlapping body of metal bearing such larger character on its face, which over.-

l lapping` portion is adapted to extend over t-he face of an adjacent smooth slug.

Although such extended character may be thus, supported from below, it is nevertheless'so thin that 't has a tendency to curl,

` especially on cylinder presses and when subject to hard usage.

' As in the case of the companion applica tion above identified, the object of the presas strong and ent invention is the avoidance of the difficulty just noted by providing a slug fully durable as the ordinary one of`uniform thicknessthroughout. To the accomplishment of this and `related ends, said invention, then, consists ofV the means hereigafter fully described 1and particularly pointd'out in the,l claims.

VThe annexed drawing and the following description setfortli in detail certain mechanism embodying the' invention, such disclosed means constitutin however, but one of various, mechanical orms in which 'the principle of the invention may be used.

`In said annexed drawing Figure 1 is a transverse section through a mold and the adjacent parts of a typograph embodying my present improvements, Fig. 2 is a perspective view of an improvedma -trix bar that forms a feature of the inven tion; Fig. 3 is a similar view ofV a blank matrix bar for use in conjunction with the foregoing; Fig. 4 is a perspective View of a slug,or line of type, cast with matrix bars of the kind just referredto; Fig. 5 is a transverse sectional view of an assembled body of such slugs; Fig. 6 illustrates a modification in construction; Fig. 7 is a section of the slugs produced thereby; Fig. 8 is a longitudinal section through the mold illustrating the manner in which a slug such as shown in Fig. 4 may becast; Fig. 9 is a similarbut broken longitudinal sectional view through the mold illustrating the manner in which a different form of slug may be cast; and Fig. 10 illustrates several forms of slugs.'

, As indicated in the above brief descrip tion of the drawing, the parts more imme-V diately affected by the present improvement arethe mold and matrix bars which' coper ate to form the slug ori line of type. The form of mold lappearing in Fig. l is that employed in the .so-called Ludlow typograph and is shown in association with the supporting bed 2. `The latter may bc regarded simply as typical of any suitable. lsupport whereon the matrix bars are adapted to rest pending the approach to the mold of the nozzle 4 of the casting pot (not shown), from which molten metal is designed to'be supplied to the mold from beneath. ,'lhc usual terminal squirt plate 5' closes the end of the nozzle and directly contacts with the mold, as will be readily understood.

termed` each have a, matrix, that isran inl taglio impression, of only a. vsingle character, and are correspondingly shorter than vthe longer bars of the Ludlow typograph whereon a number of matrices are regularly provided. These short matrix bars are furthermore distinguished from short bars heretofore employed n-l ,otherl constructi'mi'sfv of'typograph, by being more or less deejrilyy toms of these recesses 'i (seel Fig. 2). The

recesses in question provide for the formation of a slug 8 with an upper overlianging portion 9 of corresponding dimensions, when a body of such matrices are assembled, as will be readily understood.

The manner in which the matrices are thus assembled and held in place (hiring the. casting operation is a matter of indi'erence.; a simple trame lt). preferably ot' reetangular form, is shown in the drawing, while a presser foot I1 is employed to clamp bars 3 against the casting Jface ot the mold. For forming the spaces between words` as also for leaving blank spaces at the ends ot' the line wher-e the'type matter does not extend through to such ends. l employ bars l2 of the form illustrated in Fig. 3, which v(litter from the above. described matrix bars 3 in that the recesses 12S formed on their under faces are not so deep as recesses 7 and of course. do not bear matrices. Such recesses are, however, of a sutlicient depth to render continuous the overhanging or enlarged portion t) ot' the slug, as will clearly app air from a reference to Fig. 4, in which a slug formed by lbars of the kind herein described is shown in perspective. Closure ot' the. respective ends of the space above the upper face ot the. mold 1 that. is laterally inclosed by the walls of the recesses 7 or 13, as the case may be, in the asseinbled'lmrs, is ettected by means of blank bars l-t (see Fig. 8), or equivalent nicn'ibers. v

y the mechanism justdescribed I am enabled to east slugs or lilies of type having enlarged upper portions with practically the sinne. facility that ordinary slugs are cast in the regular operation ot' the typograph. As will be obvious, the slugs formed in this t'ashion will excel in dura.- bility, as woll as in the cleariiess of the impression wliieh they are capable of iving, ,by reason of the solid support affor 'ed the characters on their faces. It has already been indicated that the casting mechanism may be variously arranged, while still maintaining the :n.lvantageous features of the improved matrix har construct-ion constitoting the present invention. There is, in other words, no intention, b y referring, as above., to a particular typograpli, to imply a limitation 1n the. adaptability of the mechanism; and itshould further be borne in mind that such improved bars may be snpported 'directly on the. moldface under certain conditions, inasmuch as in the actual casting operation the bars are in effect Siml ply clamped between such face and the under side. of the presser foot, or equivalent clamp member.

Instead of positioning the assembled body of matrix bars symmetrically over the slot in the mold, as is illustrated in Fig. 1, such bars. together with their holder, may be shifted to one side. or the other as shown in Fig. (i. ln this way the form of the slug made from the composite matrix so provided is changed from that of Fig. 5 to that oli Fig. T. 'l`he offsetting of the enlarged, type-bearing portions ot the slugs thus obtained may be found desirable under certain "conditions, and it is entirely feasible to thus t'orm said slugs owing to the relatively large volume ot' the portion in question, whereas lo attempt to do this b \"siniilarly overlapping the simphI matrix would be entirely impracticable` owing.r to the chilling of the thin body of metal provided for.l

Furthermore, by using bars without any recesses at all` the corres!)ondingr Section of the slug will. of course. be reduced to simply the relatively narrow body portion. 'lhe use of such bars and the formation thereby of slugs thus reduced at one or both ends is occasionally found desirable where a line of large type of greater length than the width ol a column is beingr set up; for in such case it may happen that the space left in a slugr for one column will be just a trifle too lsmall to accon'iinodate a letter, as for example. a "V, while to shift such letter v,to the next succeeding slug would leave. too large a blank space in the word being coniposed.

'lhis and similar dilticulties may be readily overcome with the improved construction of typograph mechanism n nder cmisideration. Thus in the particularcase luider consideration, the upper` type-heal'- ing portion ofthe first slug will he extended beyond the' body of. said slug lly allowing the last bar. that carries the iiiatrix'of the letter lV in the assumed instance. to overlap the face of the mold as shown in Fig.' S. tluls leaving the end of said slug of thel form clearly illustrated at the left in Fig. 1t). l)ue note is.- of cours-e` taken of the length of the added or projecting portion of the slug` and in assembling the hars t'or the next slug.'tlie tirst bar 15 is a blank one ot' a width equal to the extra space taken by such end matrix bar in forming the preceding composite matrix. il); as a result, when the slug is cast. the. enlarged portion 9 thereof will terminate short of such end a distance. eqiuil to' the projection on the preceding slug. as illustrated at the right in ["ig. lt). When the two slugs areasseliibled, accordingly. a continuous etl'ect is secured that would be otherwise impossible.

It will he observed that in all the ilitt'erent forms of slugr obtainable by the meclian'isni herein-before described. while the body of the slug remains-of ordinary dimensions in length and width, that is of the same dimen- (see Fig,
