In carrying the invention into effect in one convenient manner, shown]. in the accompanying known, under the registered trade-mark Linotype, as an all-purpose machine, the general procedure in casting a slug may be similar 'tothat. described in the specification of U. S. A. Patent No. 2,023,557. The embodiment of the present invention now being referred to will be described. with reference to the casting of a slug containing" Chinese characters in such a machine. 7

The character indentations are formed in any convenient way on the plane face of a square plate or block a. (Figure 3) the sides of which have grooves 2) extending round the periphery. A holder for a line of'these matrix blocks a is shown in Figures 1, 2, 3 and 6, and is in the form of a substantially U-shaped channel-led. member, one of the side walls 0 being separate fromthe L-shaped portion (1 formed by the base and the other side wall, but having lugs in the form of plates e secured thereto byscrews f projecting from its bottom into guide grooves gin the;outer surface of the base proper and these lugs having pins h which engage with bridge pie'cesi screwed across the guiding grooves y to prevent. separation of the parts. -Oompression springs is between the contiguousfaces of these portions 0, d, normally hold them apart to the limit defined by the stopping pins h (thus temporarily widening the channel ofthe U-shaped. holder), but the portions can berpressed to-. gether (and, if desired, held together byany suitable locking means such as a'detent) when the line of matrix blocks has been assembled in the holder; Ribs Z are provided on the inner faces of the side walls of the holder to engage in the grooves. b in the sides of the matrix blocks a when the holder portions are pressed together,

thus locating and holding the matrix blocks in position. The side walls of the holder are suffrciently deep to extend above the plane surfaces 1 of the matrix blocks (as shown in Figure 6), and thus when a line is assembled they are equivalent ends of a line may be similar to matrix blocks tothe side walls of the recess or routing notch in a matrix of known shape with the character indented in the plane bottom face of therecess. Spacer members m (Figure 4) ,for closing the but are deeper so that their upper surfaces (which do not, of course, carry a character indentation), when they areassembled, lie flush with the upper faces of the side walls of the holder. a. The spacers may be grooved on only two opposite sides, as shownin Figure 4, instead of on all four sides which is the case for the. matrix blocks when carrying Chinese. characters (Figure 5).

Externally the holder may be of such shape (as shown in Figure fi), that when the matricesare assembled therein the cross-section of the. whole is identical with that of a known matrix, such as that shown in Figure 9 of. specification No. 2,023,557. This external shape is of importance only insofar as it is required in the machine in which the slug is being cast and may, therefore,

varyto many other shapesye. that shown in Figure 9 of the above-mentioned specification N0.

2,023,557. It will be noted that onaccount of the side groove b forlocating the matrix blocks in the holder extending fully round the periphery, the blocks can be assembled side-by-side in either of two orientations corresponding to their relative vertical or horizontal positionsv on the cast slug. This isa matter of'some importance in casting slugs from ideograph character matrices, such as Chinese. When aline of matrices and spacers has been assembled by placing them directly in the holder and-thereafter pressing the holder portions together in the manner described above, the whole may be presented directly to'the machine (if the.

machine. is such-as to deal directly with an as-. sembledamatrix line) or it may be'placed in a hand-stick. Conveniently the form of handstick employed, if the slug is beingcast in a Linotypejall,-purpose machine, may be that shown in Figures. '5 to 9 herewith corresponding toFigures '13 and 14 of specification No. 2,023,557,

the holder carryingthe assembled line ofmatrix blocks. being adapted to fit. into the. stick.

in placeof the matricesthereinshown,and the matrix blocks and holderbeing longitudinally clamped bythe screw clamping plate n illustratedv v herein; The stick is thereafter presented to the machine in known :manner. It willbe undere stood that any other convenient form'of handstick may be employed according: to the cross section of the holder and to the kind of machinebeing used.

In order to facilitate removal of the holder and matrices from the stick; after casting two aper-.--

tures o may be provided through th'e base'of the stick, and there may be provided on the machine, I

e. g., by screwing a plate 10 (Figure 10) thereon,

two studs 1", (Whichmay have rubber or fibre head portions; as shown) spaced to correspond Y to the apertures in the stick. Upstanding; plates s may be provided adjacent to these studs sothat by holding the handstick with its edges against these plates the apertures 0 stand over the studs t 7 and. a downward movement of thestick (the clamping plate n thereof being released) results in'ejection of the holder.

. In order to facilitate the assembling of the q matrix blocks a loosely in the holder before the latter is closed, a tray-like member 15' (Figure 11) maybe employed, comprising abase substantially of the same size'and shape as holder, having two upstanding contiguous side walls. This is conveniently held in. the hand, with thematrix holder therein, during assembly, the up: standing end wall a preventing-the loosely inserted matrix blocks from sliding 0ut. It should be understood that theinvention is not restricted to the arrangement in which matrix blocks can only be assembled as a line, but can as readily be employed for casting a slug from one,or from a small number of matrix blocks. Further the invention is notrestricted to. matrix blocks with ideograph or other characters,

but may be employed with matrices having any kind of character-thereon, and not necessarily adopted without departing in any way from the scope of the invention.

Having described my invention I declare that what I claim and desire to secure by Letters Patcm is:
