This invention has referenceto slug castingimachines, such as linotype-machines of the general organization represented in Let ters'Patentof the United; States No. 436,532
to Mergenthaler, wherein a slug .or lino-V type is cast in a slotted mold against a composed line of matrices which produce the type characters thereon.- In these machines,
the molds are usually-mounted in a vertical;
'intermittingly rotated :diskor' wheel which first presents the selected mold inahorizontal position for the casting of the slug, and thereafter carries it around to'ajvertical position for the ejection of the :cast slug therefrom. f a i I The lpresentzinventionis directed to an improved mounting-of the mold disk-,and one which will :admit of "its instant andconvenien-t removal foncleaning, repair or replacementyor for any otherpurpose. The
invention-also contemplates the combination with the mold disk of a cooling jacket mounted in novel --relation thereto and serv-' ing to prevent the undue heating of-theparts by'the molten metal from which the slugs are produced. "r The exact nature of the*improvementswill-hest be understood'fro'm the detaileddescription to follow; I Referring to t-he drawings v 1 aside elevation ofa portion of a li-notype machine equipped with the pres ent=improvements;- i 7 F g-2 2 front elevation of the same; Fig. 3 isahorizontal section, partly in 'plan bfthe -mold slide, the mold disk, and the associated parts;

The, journal stud F jects'a slight distance loeyond' the rear face 'of the-armeB and is formed in its proingwcasting the selected mold is presented 1 in a horlzontal position ,to receivethe molten mg is carried around to a vertical position vwhere it registers with a pair, of trimming' knives (not shown) between which the slug is e ected from the mold by the usual ejector,

As before stated, the'present. invention isf' directed to an improved mounting of the mold disk. 2 In the embodiment illustrated,
thearm'B is provided with aboss E pro.- I 'jecting v forwardly therefrom and formed with a centralbearing opening E passing v through the boss and'arm from front to rear,
Themold disk A has fixed to it a rearwardly extending journal stud F rotatab-lyzmount-ed' in the bearingopening.Ezandf e l rmow jecting end with an annular g-roove F; In this groove F, therens adapted to engage:
movable horizontally in guides G on the rear face of the arm B' The locking plate may be? operated'by any suitable means, but
in the present instance it is'connected by a link G with a hand lever H ivoted-atfitslower end to the arm '13, as at} and carryally confined thereon; whereas, when the locking plate is disengaged from the stud groove,'the mold disk may be drawn forwardly for removal from the supporting arm,it being apparent that the looking or unlocking of the mold disk 'may be instantly effected simply by swinging the hand lever in one direction or the other. By placing the guiding block H on the hand lever, the
disengagement of the locking plate from the mold disk will simultaneously effect the disengagement of the guiding block therefrom. In removing the mold disk, the vise frame D as ordinarily is swung forwardly and downwardly out of theway, as indicated by the'dotted lines in Fig. 1.
In order that the'parts will be prevented from becoming unduly heated by the molten metal injected into the molds during the slug casting operations, a hollow annular cooling jacket J is placed around the boss E and in the space between the arm B and the mold disk A. This cooling jacket is confined in place'and against rotation by means of a number of fastening screws J passing through lugs J on the jacket and screwed into the supporting arm. The heads of the screws J arecountersunk in the lugs J and are so spaced from the front face of the supporting arm as to permitof a limited axial movement of the cooling jacket. Expansion springs K, seated between the supporting arm and cooling jacket, act to press the latter up against the rear face of the mold disk and hold it in yielding contact therewith. A cooling medium, such as water, enters the jacketby a pipe L connected thereto atone side of a partition L, and after flowing around the chamber L leaves the jacket by a pipe L connected thereto at the opposite side of the partition.
In the accompanying drawings, the invention has been'illustra'ted merely in preferred form and by way of example and as applied to a linotype machine, but obviously many changes and variations thereinand in its mode of application may be made without departing from its spirit. It
- is to be understood therefore that the invention'is notlimited to any specific form or embodiment, except in so far as such limita tions are specified in the claims. 7
