.gra hical Composing-Machines Equi pe'd wit Alternative Fonts, of which the f0 ow- 111%183. specification.

he present inventlon relates to im rove ments 1n the assembling mechanism 0 typographical composing machines equi ped wit alternative fonts. typical mac me so equipped'is the two-letter variety of the Mergent aler linotype machine. :Each of its matrices is practically a rectangular plate:

having a recess in each side edge and the formative cavity for therespective type face:

in and: across one of ,these edges, so that the cavity. for the alternativevfont mustbe either'.

above or below the one for the normal font. Thls being the case, the alternating'motion' necessary to make a matrix present the desired cavity in the. composing .line, must always be a vertical one--see the specifications of LettersPatent. Nos. 449872, 547633 .:.and 615909.

In. the accompanying drawings which are to-be-takenas part of this specification and read therewith :-'Figure 'l is a front elevation ofzas-much of the improved assembling mechanism as is necessary to illustrate the Ian of the assembler broken away; Fig. 3 is an elevationas seen from the right-hand side of 'Fig. 1, and shown partly in vertical section on the line 33 of that figure; Fig. 4 is a. vertical section also taken on the line 33 of Fig. 1 but showing the device under a different condition ofadjustment, and Fig. 5 .is .a side felevation showing parts of the 5 mechanism represented in Fig. 3, in a dif ferent position from that in which theyare shown lnthat figure.

In'the drawings, see Figs. 3 and 1, two

matrices l .-are--represented in dotted lines, the two-formative cavities 2, 3 being for -L.producing printing faces of respectively normal'and .variant font. "When the normal formativecavities '2 are .in the composing. Q E

.line,,as in Fig 3, thetwo bottom lugs 4, 5-

each of the matricesl' rest upon the ledges 6frat-the back of the front p ate .of theassembler 8, and-the ledge 7 being .formed at the front of the back plate ofthe said assembler.

.There is a further ledge 9 referablypn the back of he front plate 0 the assemblerS and parallel with the ledge 6 and with its upper or supporting surface at a height ovethat of the ledge 6 equal to the height L of the formative cavities 2 above the formative cavities, 3 on the matrices themselves. The ledge 9 stops short of the entrance mouth 10 of the assembler 8 by a distance not less than the thickness of, the thickest matrix in a font.

So far. ,as has-been above described the ;plementary ledge-11 preferably formed integrahwi th a vertical plate or slide 12..and capable of a vertical motion betweentwopositions, in the lower of, which, as shown in Fig. 1 it is in register with, and virtually forms -a.continuat1on of, the led? 9,,and in the upper ofwhich, as shown in ig. .3, it is out of'register'with the ledge 9 and at a height considerably above it, so as toallow the matrix lugs 4 to pass beneath it onto the ledge 6 which'latter, as ordinarily, extends to the entrance mouth ,10. The supplementary ledge 11 may be guided in its vertical adjustment by means of screws 13 which and 7 respectively,-the ledge 6 being formed pass through a slot 14: in the slide .12 and screw into the front of the-assembler 8,-there being provided spring washers 15 on the screws 13, or other e uivalent devices, for

presenting sufficient riction for retaining the sup lementary led e 11 1n either of 1ts adjuste positions, until the operator positively moves itfrom such position for effecting a change of font. For facilitating theadjustment of the ledge 11 the slide 12 is provided with ahandle 16.

When the supplementaryledge 11 is in its;

normal.formative'cavities 2 in the compos i-ingline. When the ledge 11 is its .lower position, in which it is shown in Fig. 4, and therefore- ,irfregister with the ledge 9, the lugs' l," rest upon it, so as to present the variant formative cavities 3 in the composing 5 line, which presentation will be maintained for the matrices already entered, by the ledger 9. This invention allows the operator to change'the position of the ledge 11 as soon as'he is ready to change font in his composition, so that if, immediately after a matrix has been stopped by the shelf 11 for assembling its varlant formative cavity 3 in the composing line, as in Fig. 4, it is .required to assemble amatrix with its normal formativecavity 2 in the composing line as shown in Fig. 3, and the shelf 11 s raised for that purpose, as shown in that figure, there is no necessity :to manually-push the ff variant matrix off the shelf 11, as has heretofore been the practice, because this variant matrix will be automatically pushed-off the said shelf 11 by the pressure of the following matrices whether assembled normal or variant The assembler of the Mergenthaler linotype machine is raised. quickly after it has received its line, thereby imparting a certain momentum to the matrices in it and one which, unless thwarted, would disturb the alinement of the composed line of formative cavities. This momentum is thwarted in the case of those of the normal ifont matrices which have passed the supplementary ledge 11, by the fixed ledge 9, under which the lugs 4 of the said matrices are then situated, and in the case of the variant font matrices it is thwarted by a rod up-to which the assembler 8 in its ascent brings them; thisrodconstitutes no part of the present invention and is therefore not represented in theaccompany ing drawings. In the case of those of the normal font matrices which have not passed the supplementary ledge 11, the abovenam'ed momentum is thwarted by a horizontally slidable detent 17, Figs. 3 and 5,-oapable of sliding through the back of the assembler 8 so that the forward end of such detent may be caused to eitherproject to the front of such back and into the assembler as shown m Fig. 5 or not to so project as shown in Fig. 3 in the former of these two last-named'positions the forwardend of the detent 17 projects over the matrix lugs 5 and thereby holds the matrices down upon the ledges 6, 7 and in the latter of such positions 1t 1s out of the path of the matrices entering the. assembler. The detent 17 is operatively connected with the lower end of ,a lever 18 pivoted tothe back of the assembler 8 and eb'ftionary cam. 20 fast to the ace plate 21 of upon whose upper end acts a spring 19 which .the machine, this cam beingso situated as to "withdraw the detent 17 from within the as-" sembler when the latter has almost com;

[pleted its descent and to-maintain it in such withdrawn position until just after the com- .menoement of the assemblers ascent. h!

The-before described ledge 9 may bgi either fast to the assembler or movable therein, in any of the -ways already known in connec tion with such devices.

In respects other than those hereinbefore particularized the devices shown in the accompanying drawings may be of ordinary construction.
