TYPOGRAPHIGAL MACHINE'.

Specication of Letters Patent.

To all whom it may concern Be it known that I, JOHN It. ROGERS, a citizen of the United States, residing at Brooklyn, in the county of Kings and btatev of New York, have invented certain new and useful Improvements in Typographical Machines, of which the following is a speciication, reference being Ahad therein to the accompanying drawing.

My invention relates to, typographical machines, such as linotype machines of the general organization represented in Letters. Patent of the United States No. 436,532, to O. Mei'genthaler, wherein circulating matrices are 'released from a magazine in the order in which their characters are to appear in print and then assembled in line,- the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or which produce the type characters thereon, and the matrices thereafter elevated and returned through a distributingmechanism to the magazinefroin which they started.

More particularly,.`t relates to that vclass of machines in which are employed type or matrices provided' with two or more superposed characters, and devices` by which the' vertical position of the type or matrices in .the composed line may be varied so that f each will present one or another of its characters in operative position, as demanded. The matrices when thus assembled at different levels are carried in this conditionA to the casting mechanism, and are subsequently brought to a common level preparatory to' distribution. Various mechanisms have been employed to eect the leveling of the matrices, one form being shownv and de- Letters Patent No.

835,256, wherein a pair of'inclined blades are located'in the stationary upper transferl channel in position tomengage the elevated matrices in the line, as'y the latter is transferred from the first elevator, and thus to them to the 'level of the lower depress matrices.

cip ally with present invention is concerned printhis method of leveling and aims to secure the same result in a simplified and convenient manner. As is well known, the first elevator is ordinarily provided at Aits open end with a pair of retaining pawls which engage behind the last matrix inthe linotype against the matrices ledges- B1 andf B2,

line and prevent its displacement therefrom BROOKLYN, NEW' YORK, ASSIGNOR TO MERGENTHALER LINOTYPE n Patented Jan. 16, "19am Application filed February 24, 1915. Serial No. 10,165. i 'i during. the movements of the elevator,

Specifically, I propose to construct these retaining pawls of such form that theyi'notfv only serve tohold the line within the ele-A vator, lbut in addition act upon the matrices as they are transferred therefrom .and bring them toa commonlevel.

In the accompanying drawing, I have vshown my invention in preferred form and by way of example andas applied to a linotype machine, but obviously many changes and variations may be made therein, .and in its mode of application, comprised within its spirit. f y. ,Y

Generally speaking, I desire itto be understood that I do not limit myselfto any specific form or embodiment, except in so far which win Sau `a; i

as such limitations are specified in the claims.

Referringto the drawing: ligurey l is a front elevation, partly broken away, ofthe first ,elevator and 'intermediate channel of, 'a

linotype machine, having my invention applied thereto; ing the first to the second elevator in operativev relation elevator; Fig. 3 is asection on Fig. 2 is a similarv View show- Y* the line 3--3 of Fig."2; and Fig. 4 is adetail-view.

In the accompanying drawing, I have shown only such parts of the machine as are necessary to an understanding of my invention. `The other parts may be of usual` construction, such as illustrated in the Mergenthaler Patent No. 436,532, before referred to, or as embodied in the commercial linotype machine.

The type or matrices X after being composed in line are transferred through the intermediate channel A to the first elevator B, which,after presenting them tothecasting mechanism, rises to the position shown in Fig; 2, when the matrices are moved from the elevator by the transfer device or pusher C into the upper transfer channel F and onto the toothed bar D1 of thesecond elevator D, whichthen carries them upward for distribution into their roper magazine, all in the usual way. Re erring to, Fig. l, it will be noted thatthe intermediatechannel A is formed with ledges A1' and A2, and that the first elevator B is also formed with the latter ledges registering with the former, when the parts are in esi - the pawls and move them vertxcally. Since,

however, I propose to rely uponthe lnclined surfacestEHto depresstheelev'ated matrices transfer through'the machine. The ledges- A1 and B1L engage beneaththe upper ears of" l n l tegame i the position shown, so as' to provide vcon-. f-

tinuous tracks upon which the matrices may be supported at different levels in their the matrices standing' atthe lower level,

while the ledges A2 and B2 engage beneath the lower ears of the'matr'ices standing at the upper level. Similarly, the upper trans-y fer channel F is formed with ledgesl F1 adapted tov register with the upper ledgesL B1 of the first elevator, when' the Ylatter occupies the position s howninFig, 2, so as to providea continuous lsupporting track for` vthe matrices as they are transferred from the elevator 4onto th'e'toothed barD1.v

.. -a pair of 'pa'wlsy E, which are located .in re- -In accordance withfmy invention, the 'first elevator B is providedat-itsopen end 'with cesses B3 in thev side walls of the elevator and are pivotally mounted upon transverse studs E so as to' be movable-vertically., Ar-l. ranged beneath the rear ends of the pawlsf,

l `are. springs E3 tending to lower their'for'- ..ward ends to theposition shown in- Fig 4',

pins E4 fixed to-the walls of theelevator actclined surfaces E1 toengage behind the lastv ing to arrest the pawls in this position. vThe forward portions ofthe pawls are, offset, as.

at E (see Fig. 3) so asto'overlie the matri'ces, and are formed with inwardly 1nmatrixain thev comp'osedline andhold it in Vaa' proper 'position (see Fig, 4.).. The forward portions' of the pawls are'alsoA formed lwith outwardly inclined surfaces E2, ".vhich'a're adapted to be engaged by the matrices as they vare transferred intovthe first elevator "from the intermediate channel,` and@V thus ,cause thepawls to move vertically (as shovvny by dotted lines in Fig. l) against theyactioir- "of theirspiingslil8 and'permit the passage'. of the-matrices thereunder.` Similarly, when I' the matricesfa're transferred from th`e`first" elevator into the, upper transfer channel F,

' .G located in the fixed framework and )having y '-55 a. p air ofprongs G1 to project into the` re# they will engage the inclined surfaces ll of tothe -leve1 of the lower ones during their transfer `from the elevator, means 'are provided to limit the upward movement of the- 'awls at such time In the'present instance, enploy for this purpose a forl edmember cesses B3v of the elevator-when the*P latter arrives at its uppermostl position and arranged to be engaged'bythepawls asthey.

' are elevated by' the matrices'during their transfer fromthe elevator' (see Fig. The 'operation of the parts will j now be clear. Vhen the first elevator B isqempty and in receiving relation to the intermedi ate channel fr, the pawls occupy the position shown. fr. A s the composed lineis' transferred into the elevatongthe matn rices engage the inclined surface E2 of the pawls and lift them against the action of their springs E3, the extent of such lifting being governed by the constitution of the Icomposed line, that is to say,'accordinggto whether the matrices all stand at the same levelv or at different levels therein. If the matrices all stand atthe same level, then after the composed line enters the elevator;

thepawls are imm'ediately'returned,to their original position (as shown in Figl) with their inclined surfaces El engaging behind the flastanatriit in the line. If,.however, the last' matrix. in thecomposed line is standing atthe upper level, thepawls will occupy the position sho-wn by full 'lines in Fig. l.

The vfirst elevator BI now descends to pre-y sent the linej to the casting mechanism and subsequently ascends to carry it into registryfwiththe lupper transfer channel F, at whiclr timer-the transfer device C moves it from the elevator-into-the channel. During `such transfer, kmatrices standing at the lower level,engagethe-inclined surfaces E? of the pawlsa'nd'merely raise them sufficiently to permit their passagey thereby. However, any matrices'standingfat the ,upperflevel tend to lift-the pawls to agreater extent, but this v tendency is resisted and overcome by the engagement of the .pawls with the prongs Gf of the fork G, thepawls being thus maintained in a substantially rigid condition and -in such position that their inclined surfaces YE1 engage the elevated matrices, as they are successively A slidv vofi' their sustaining ledge B?, and positively depress them to the -level of the lower matrices, when they may vpasstherewithalongthe ledges'F1 of the upperftransfer channelF andonto the toothed bar D? of the second elevator D.

(See Figs. 2 a'nd.)

It will be understood that while' I have designed thelpawlsl E to subserve the two `functions noted, they may `be employed to perform one .or another thereof lndependently, as it willbe. apparent'th'at they ymay be used advantageously for either purpose` .depending, upon the style 'offmachine to which `they are applied. l v -f Aspreviously stated, I ha-vefshown my invention merely in preferred 'form-and by way' of example and it will be obvious `that many modifications and alterations therein,-

and in its mode of application, will suggest lle 12e' 4`themselves to those' skilled in the art with# i levels therein, a device to vtransfer them lac therefrom, and a movable member carried by the elevator and having an inclined surface to engage the type or matrices during their transfer therefrom and bring them to a common level, the said member being provided withg an oppositely inclined surface which is engaged by the type or matrices as they enter the elevator and thus displaced thereby. y I
