mom FOR LINE-CASTING MACHINES.

A'pplication-fil'e'd February 20, 1925. Serial N0. 10,463.

This invention relates to 'line casting -r'irachinesand more particularly to the alinin ofthe matricesin front of the mold.

lVith the molds'in general useit is impossible to cast'a slug that will print letters of dilferentsi'ze'all ofwhich will be alined at their feet.

If it be attempted touse severalletters of varying height in one line, the resultwould be that all of these letters wouldbe alined along t-heirt-ops and thereforethe practice is not followed. However it is'often desir able to use letters of different sizes and among the objects of thisinvention is to provide a mold capable-of eastin-g a slug having thereon lettersef different height alined at their feet.

Another object is to provide'a manner of suitably adjusting the length of'asl'ug.

I Other objects involving novel constructionsand combinationsof parts will appear in the specification, and in the claimsthereof setting forth afp'referred 'embodlment of my invention which will 'be 'fully understood from the detailed description and drawings,

Fig. is a similar View of a largertype matrix against the same type rail block.

Fig. 18 is a sample of a'slug having different sized type lined up on a lineof feet.

'Ordinarilythe mold disk 1 has'mounted thereon a pluralityiof'molds which are adjustable in turn to a position in front of the mol'd'slotby'means of a turning'knob 2 and pinion 3. In my disclosure I have illustrated two molds; the'upper one' in Fig. 1 'being for ordinarytype, and the lowerone being forlargetype. 'Each mold h s a right angle-member havingone flange 4 securely fastened to the diskby screws while the other flange extends out perpendicular there- -to and-forms the capping piece6 of the-mold. The lower face of this piece is the datum line'parallel to which the feet of letters of all sizes are dressed.

Just beloweach m'old'there is looated 'a bar 7 securedto disk 1 by screws 8. This bar serves the purpose of supporting rail block "9 and hasgpassingthrough it forthis purpose a plurality of screws each having a spring 11 under compression and constantly tendmg to I raise the rail block. The lower end of each spring "bears against the bottom of hole 12 in member 7 while the upper end bears against arecess in-rail block 9. The

threaded end of the screw is screwed into a tapped hole 1 '3 in the rail block and-as the screw is unscrewed springs 11 will elevate rail block 9. a

Therail 'block"9"=must be keptxat or very to a constant *distance from the mold ea'ps '6' fora selected set of matrices andthis isaecompl-ished by linersl l and and a *fill'er'lfi, if such he necessary. These liners are of a definite length and the right hand one always has its lef-t'e'dge at the'zero mark of the length of the line scale onfflange 4:, whil'e the left hand one may be positioned along itslength in-nrder' toli'm it the length 0f 'slu-gto'be'-'cast. The-depth of these liners depends nponthe-size ot the type'to be used.

As is very-often the case, the constant distance between the top of the rail block 1 and f the'mold cap is greater than 'the depth of slug that is to be cast so 'I-providez-a fil;

I er bar 16, Figs. and "'9,-to jtake up the difference Upon: changing thesiae 6f type to:

.tions ofholes in a lower point a filler bar of correspondingly greater depth must be inserted.

For compactly securing the liners, filler bar and rail block in a definite position relative to the disk 1, there are provided locking members 17 Figs. 5 and 10, each having two pins 18 and a knob 19 to facilitate handling. These pins pass through holes in the respective members and when the looking members 17 are in place they are secured by a latch 20 pivoted at 21 which is swung down and over the top of them.

The adjustment in the length of line of type to be cast is made bymoving liner 15 in which there are six holes to the inch allowing for a variationin length of one em. In order to be able to change the length of a line by one half an em, four holes to the inch are provided in the left hand end of filler bar 16 and railblock 9, andthe half em variations are obtained by passing the pins through various combinathe liner and of the superposed holes in the filler and rail block. It is obvious that other combinations of holes could be provided to allow for a shorter change in length of line if such would .be desired.

Three rails 22 are provided and, with any one of which, matrix Q3may be alined by itsear 24. Should the matrices be alined against the lower rail as shown in Fig. 13, i

the upper type on each matrix would be cast, and, if it should be alined against the center rail as shown in Fig. 14, the center type would be cast. Thus it is possible by the use of the three rails to bring any of the three different type carried by one matrix, Fig. 15, opposite the mold slot and cast aline, having any arrangement desired of these three type.

The matrix used may have any desired number and variety of type and I have proposed the .use of one having three type of the same size allowing for selectivity of either a roman, full-faced, or italic letter (Fig. 15). Each of these letters are positioned on each matrix so that whichever one is chosen to cast a letter in a line on a slug,

it will'be dressed with the other letters of the line on a line of feet as shown in Fig.18.

Since the rail block and its rails are always kept at a constant distance from mold cap .6 bylthe use of liners and a filler bar,

the letters ,w1ll always be alined along their feet and several sizes oftype may be cast in proper alinement as shown in Fig. 18.

The lower mold for large type as illus trated in Figs. 1, 7 8, 16 and 17 is substantially the same as the mold for ordinary type, above described. The rail block 9 cap 6. The shape of the block requires the use of two liners having narrow retaining and the top of the block 1 extends nearly to the lower surface of mold edges 25 and deep fronts 26, but holes similar to those in liners (Figs. 11 and 12).

As illustrated in Figs. 16 and 17, matrices of various type sizes may be alined for printing a line of type with the result that all of the type are alined on a line of feet as shown in Fig. 18.

My invention is capable of-a wide variation and relationship of parts without departure from the nature and principle thereof and I do not restrict myself unessentiallyin the foregoing or other particulars, but contemplate such alterations and modifications within the scope of the' appended claims as maybe found .to be ad.- visable.
