The .mold disk is rotated, `as usual and Well known in imachines of this class, `to presentthe `mold to the matrix line andzcasting'mechanifsm Vfor .the nfj ec'- tion of `molten metal into the mold slot and against :the characters in .the :matrix line, and to carry the mold containing the 'cast slug therein to'a position in front offejecting .mechanism linfcluding a blade which is movable .forwardly from the' :rear side of the -mold through the mold slot to eject the slug edgewise `and in adirection transversely `of Vits length from the mold.

The slot 6 in which the slug is cast isms-posed between. .the cap and. .body of the mold, Vit being defined iby the bottom vor ycasting {acelof the cap and the opposedupper or casting face of the mold body, and theends `oi" the casting slot are defined `by the right hand and left hand liners Jfl and 8 respectively, Wliichrmay beof dineren-t thicknesses according to V-t-he `separation desired between the capr and `body of the mold inforder to vary as desired the thickness or'-poi1it lsizeof the slugs to be cast in the Imol-d.V .The 'liners l and 8 are provided -with bores 'Siv and I0 r-'espee-fV tively to receive short studs -91 and' IIll' respectively `Whicl-i pro-ject downwardly from the bottom :face of Ithe mold cap, and short 'studs "9b and IUb respectively which project upwardly -f'rom the upper lface -o-f the Amold Ibody, these studs serv-ing -to `accurately locate 'the liners and-fthe mold cap longitudinally respecttovfthe mold bod-y. f

Theiadvantages of therib and groove construction for the liners andmol-d as just described are of particular importance under certain con` ditio'nsr in the operation of typographical ma-U chines of the class referred to. For example,l if

' -the system employed inV respect to mold liners isv toiremploy a series of left rhand liners ofY different Vlen'g-thsifor varying thelength of the mold slot .for casting slugs of 'differentlengths Vit will beY seen. thatto obtain -a relativelyk short mold slot, 3 the left hand liner in Fig. 2 may be of a'ilength to .extend from the'extreme lefthand endof the mold body to a point indicated. by the dotted line A, andwithout the rib 8a on the liner andthe cooperative groove :in the mold body, a liner of l such length'would be anchored or held against lateral displacement in the mold only 'by the studs IUE and Il)b and would be held against lateral swinging displacement aboutthe lstuds Illa and Il)b only by the vfrictional engagement between Vthe linerand the opposedcarstingfaces of the mold capandbody.V Without the rib on the liner andcooperatinggrooveinLthe mold. body, the linermight be inserted carelessly withoutbring- Y ing its edges flushY with the front and rear faces of the'moldebefore securing the bolts 3, which would be objectionable and-iisV avoided by the present invention. Also,when employing an. ad-A instable liner, such asthe liner` I3 having a rib 13' on its underside toiit intothe Ylongitudinal groove ||:in..the1upper or casting face. of theV mold body 2,'to vary the length of the mold slot or dividethej slot'intofa plurality of compartments', as indicated -by theV dotted lines inV Fig. 2, the rib I3?A on-.suchaliner and theV cooperative groove Y I 'inf'the mold body serve'frto- .positively Ylocate and firmly retain ysuchY liner against lateral displacement.; When using the adjustableliner i3, the left hand liner 8 is made relatively short,

' shown in Fig. 2,V andr theV liner I3 is placed adjacent to the liner 8 soy that the length of the mold jslotbetween the-liner faces |,4 and I1 atV opposite ends of the mold will be such asV to give i, the maximum length slug for which the -mold' or theV machinedis intendedV to cast. Thus, ,if `the machine is limited to Vthe, casting of .thirty em Y the lin-er faces I4 and` I 1 -wi1l bethirty ems when the`liner 3 is placed against the Vend of the *liner 8. If it is desired to adjust the mold .slot

to a length less than thirty ems, the shortliner I3 is moved along the Qmold'slot between `the mold capV and body to the desired point as shownA for example by the dottedlines in Fig.2. Under this condition, the slug would vbe cast betweenthe faces I4 and I1 of the liners 1 and I3 respectively,

i being offset outwardly and during casting of the first slug, metal would also be injected into the vacantportion of the mold slotV between the face of the liner 8r `and in thefmold until such timeasvitfmay become necessary to change the-lengthoftheactive portion of the mold slot between theleft; hand and right `hand liners. .The liner `I3,' when once placed at the desired point in the length of fthe.y

mold .slot will be firmly retained against lateral the face I8 of the liner '|3.Y The dummy slug thus cast in the vacant portion of the mold slot i Vduring thei-lrst casting operation would remain displacement by engagement of itsl "rib |3ak in .v

the groove' in the casting face of Athemold fbody, vand such engagement of said rib and groove will locate this liner laterallyA Withits front .and

rear edges flush with the front and rear faces of the'mold. Longitudinal displacement ofthe linerV I3V is prevented by clamping thereof between the According to another embodiment of the ini vention,.shown in Figs. 3, 6 and '7, a longitudinally extending groove I9 is provided in the upper or casting face of the mold body Zand extends across saidface, this groove being wider and deeper than the groove I I` previously described.. The lefthand g Vliner 2li'A carries a. rib. or longitudinal .projection body, .thejin'ner end v25 ofthe rib Vor member- 24 from the inner face 26 of the liner `23. j

When the left hand liner 20, Vwith an inner Vfacer Y 21 is used to give the maximum Ylength to' the mold cavity, the. rib or membery 2| secured to the undersideofthe liner 20 will be of Vsuicient length to`V reach beyond the` inner end .26 of the right ll'up thegroove I9zto present av smooth or unbroken castingface on the mold body,- the ribA or V member 2| .being otaj thickness Y. equal tothe Vdepth yofthe grooveV |9,.a`nd.the rib ormember 2| willoverlap the right hand liner 23and substantially meet theend 25 of Vthe rib or member '24.

Von the underside of theliner 23, thusserving to hand liner 23,1and when placed in the mold it will produce a metal tight joint between the end 26f of the liner 23 and the mold body. On the other'` hand, if it is desired to use a left hand liner simi.

II in the. castingface of the mold body, metal will flow into thisr groove over the extent thereof exposed vbetween the inner faces of the right hand and leftv hand liners when a slug is cast. However, this groove II is; ofv such small dimensions that, although it serves'` adequately for locating and rmly anchoring `the liners against lateral displacement, the bead cast on the slug will be so narrow that it. will not interfere with the pushing of the slug edgewise forwardly out of the casting kslot in the usual manner. It has been found in practice that by forming this groove I I with its side walls 39 and 3| perpendicular to the casting face of the Amold body, the bead cast therein and formed on the slug will be instantly sheared from the underside of the slug when the llatter is struck by the usual ejector blade'to push the slug forwardly out of the mold, the bead cast in the groove II remaining therein. After the -rst slug is cast, subsequent slugs will not have such a bead formed on them, since the groove I I will be filled by the bead sheared off the first slug. It is only necessary to lift the sheared off bead out of the groove I I when different liners are placed in the mold.

In the embodiment of the invention shown in Figs. 3, 6 and 7, a smooth or unbroken casting face is maintained on the mold body, the rib or member 2l being of such a thickness that its upper face is flush with the casting face of the mold body.

In each embodiment shown and described, the cooperative groove and rib serve to accurately locate the liner in the mold with its front and back edges flush or in face-wise alinement with the front and back faces of the mold so that these faces will form the required metal-tight lock up with the matrix line and usual metal pot mouthpiece, and to securely hold the liner against lateral displacement from the mold under the force applied by the usual ejector blade 32 in a direction transversely of the length of the mold, as indicated in Fig. 4, incident to the ejectio-n of the slugs from the mold, such holding of the liner or liners being rendered especially effective by engagement of the rib or retaining member on the liner with the mold adjacent to the inner or casting end of the liner.

Furthermore, the present invention provides relatively simple and eifective means for locating a liner at different points in the length of the mold slot and securely retaining it against displacement in a direction transversely of the mold.
