original application' iiiea Januaryesgwzi, serial No. 441,077. Divided and 'this appiieatioii ined October 27, 1923.

Y My invention relates to improvements in p type slug casting machines, and hasespecial reference to machines which arecommonly .known as linotype or line casting Vma- 5 chines.

In a machine of thiskind, as commonly."

constructed', there is a mold wheel vwhich carries several moldsin which the slugs are cast and which is adapted to be rotated to position the several molds in various positions for the several operations of casting, ejecting, etc. Associated with the mold wheel are means for supporting the usual matrices for castingprinting slugsorwhat is known asa quad block slide holder for casting borders or line printing slugs, etc., or blanks. Y

This present application is a division of my copending application ,Serial Number 141,077,- led January 29,y 1921,--andis directed particularly to the idea of the ree cessed slides in combinationwith the low mold for producing slugs otvarious'heights from those which are equal in height to the thickness ofthe thin mold, I employ, viz,

425 low quads or furniture, tothe ,full height slugs and also tothe means which I have devised for making. it possible. to practically use thelow .or thin mold. in standard linel Ycasting machines 'of the linotype class.

- In the printing art, differentv kinds of printing plates 'are made use of which owing to their method of manufacture havel dit- 'erent thicknesses. For instance, stereotype plates are .159 of an inch in thickness.; zinc plates .065 of an inch thick.

My lnovel low or thin Vmold ispreferably about one eighth of an inch thinner; than the standard thickness mold and by the use of quad block slides recessed, on theirmold cooperating faces to suitable depths7 I am enabled to: produce foundations 'for these various printing plates jon the otherwise standard linotype or line casting machines.

My invention will vbe more readily understood by reference -to the accompanying drawings forming part of this specification and in which Figure 1, is a face View of a mold `and wheel, the mold wheel being indioa'tedrin dotted lines; 1

Figure-2, is a vertical section of the mold onthe line 59h-2 of Figure 1 and showing associated parts of the machine;` Y Figures 3 to 5 inclusive, are sectional '-viewsfshowing different slides for use with Y Serial No. 671,133. ,f

the low mold andthe standardslide block; y

and y f Figure 6, is a diagrammatic view illustrat ing the related heights of the several slugs produced. Y

y In the so-called linotype machine a mold wheel 1 isprovided, usuallycarrying four molds, similar to that shown vat,2,on its face, said molds being equally c ircumferen'l tially spaced thereon. Each moldconsists of a base 8 rigidly secured to the Vweb ofthe wheel usually byscrews 4i and a removable cap 5 heldin position` by s'crewsA projecting through the outer partror rim of the mold, wheel. The cap `is adjustable from and toward the base for providing a moldfslot 7 between the base and cap ofdi'erent heights or thicknessesfor producing slugs ofrdifferent thicknesses. The cap is spaced from the base by liners 8 and 9at the'ends ofthe slot7., f f Y Standard line casting .machines as constructed are adapted to cast slugs of full printing height, viz, .918 inches lin height from theprinting face to the baseiofthe slug. lAll but a very small part offsuch total height, viz, .O43 of'an inch Yis'ltormed l' Y inthe mold, the balance of`.043 of an. inch being formed in the matrices.k y i I. purposely make the mold 2 of less depth from front toback than the standard mold preferably byl about one-eighthsof` an inch,

be cast in the mold slotawould be equal'in height to the thickness Vof the mold. ,Such

Alow slugs are especially adapted ,for useas low quads or'type furniture.; This low, quad v.is less than standard printingheightby the reduction of the mold in thickness,.viz, onej eighth of van inch plus vthe depthofthepart of a" printing slug produced in thev matrixV` cavities, viz, .0430i an inch or aboutr one- 'c sixth ofan inch;l Y Between this low quadheightand .the full printing'height I produce quad or printers slug material of any height ;desiredbypro' viding slides, rsimilar to the extrathick'slide 1Q as shown at 14, Figure 4, and 15, Figure -and inorder to cast low quads or type furnip Y ture I provide a blank slide 10 formounting height of l.' `:The A.slider 14 withathe; shallow recess 16 Y' Y I in'co-operation with the low'mold 2 proll 4init between the quad block 11 and the adjacent face of the moldv and I provide the operating ,face othe- Vslide with a recess, as shownV at 16, Figure'cfor at 17, Figure '5, of greater'or less depth depending uponthe slug material wanted.

duces slugs 18ct a height suitable to be used as foundation material for stereotype plates l' Vand the slide 15 with its deeper recess 17 V Vinl cti-operation Y, with the low mold .2 produces slugs'19 of a height suitable Jfor use as foundation material for zinc plates.

In FigureA 6v I have illust-rated diagram-y 1 maticallythegrelation of the severalrdiierf entheights otslugs,the slug 2,0 representing a. -full height orv printing slug.

"It will nowV be understood that 'by use `of extrafthick slides recessedmore or less, or with plane faces, I can produceslugs of yany height desired-from a'lowquad to practito @befrotat'ed to carry calyl a full height slug.

e mold, as already explained, is mounted on a-mold wheeland the wheel is adapted the nmold from the casting position,shown infull'lines in Fign ure 1, to' the slug ejecti-ng position, shown in dotted'` lines, that'is 9OYdegreesVVV to, the right Y from thecasting position. In this position n ofthe-moldan ejector blade 20 is pushed ainto the mold slot -rom `the rear to force thel cast slu'gforwardly'out of the mold. It
