sizes of type bodies or slugs while at the same time maintaining the ideal base line of the characters invariableand constant.

v Line-casting machines of the kind in question usually includetype matrices assembled" 1 temporarily'in line and'susp ended iniade vice known'as thefirstelevator, so "as to be lowered thereby to a position in front of a horizontally slotted mold whichis thereafter advanced facewise'against the said matrices Which'close the front of the mold while it is being filled from-the rear with molten metal to'produce a slug on the front edgeof which the type characters are formed by themat;

rices, or in other words upside down when 1n the casting position, and heretofore it has been the pract ce to have characters of dlf- "ferentj sizes arranged to have a common alinement-at the base of thecharacters.

The main object of the invention, as above stated, is to provide a' mold which can be readily'adjusted to various sizes of type bodies so that the ideal base line common to all characters of different size is always at the same distance from the center of the mold carr er. In carrying out the'ob ect ot the mvention I provide a frame hav ng a substantially rectangulariopening therein in i I which are mounted top and bottom parallell'y arranged members to constitute the opposite side Walls of the mold forming the" moldf slot, one of which member is adjustable relative to the other in the frame to vary the width of the mold slot for: 'typebodies of different heights and thicknesses of slugs,

with liners in the form of. plates of a thick 'ness to correspond with the height or thickness of the type body or slug'to be c'a st inserted between said 7 mold members, the op osed ends of which liners constitute theend walls of. the slot in the mold, and a liner or.

plate proportionalin thickness to the liner-sf inserted between the mold membersis in figures bear the same reference character'sin 1 serted between. the bottom mold member'and the frame wall, adjustable means; being pro- 7 vided to position the other mold member and] I f I rier 1s shaped'as usual to form awh'eel'l and whereby the mold slot will at all tiin'es be arranged so that the ideal base line of the characters when the matrices are presented to the mold is always at the same distance from the center of the-mold carrying wheel. In other words the opposite wallmembers otherfto adapt'the mold for the casting of slugs 'of'variable thickness while maintain ing the ideal base line of the type bodies or of the mold are'adju'stable relative to each' I characters, whatever the" size of the latter may be, constant and invariable. I

A further object-"of my invention'is to pro vide a means for maintaining and securing. the bar in the type slot during the trimming operation. 7 With this object in view I provide in the casting mold a pluralityof movable pins adapted to'becaused to project T slightly into the ',moldsl ot while the liquid metal is poured into'the mold and while the mold is moved from the'casting position to the ejecting position and tobe withdrawn from the mold slot'when the ejecting position is reached and the slug is to be ejected from the inold slot.

Inthe accompanying drawing forming a part of this specification Ih'ave shown, for

purposes of exemplificatiom fprefrred bodnnent of the invention:

Referring to Figures 1 to i the mold caradapted to carry a number of molds inre cesses provided in the wheel for the purpose;

The molds are brought, by the rotation of the Wheel, into the casting position and when the casting operation is finished, the charged mold is moved by a partial rotiition of the Wheel 1, say one fifth or one fourth of afull revolution, into the ejecting position where the cast line is ejected by the ejector in the usual manner, the Wheel being seenred or looked against movement oppositethe ejector during the ejecting operation.
