Anderson, Brooklyn, N. Y., assignor to Intertype Corporation, Brooklyn, N. Y., a corporation of New York Application July 17, 1933, Serial No. 680,836 In Germany November 22, 1932 8 Claims. (01. 199-57) The present invention relates. to improvements character bearing portion of skeleton slugs is cast in molds of the kind employed in line casting so that such liner will determine the length of machines for casting type bars or slugs bearing both the body and character bearing extended characters along an edge thereof, such molds as portion of the slugs. In carrying out the inven-r commonly used in line casting .machines comtion, the ordinary flat liner is adapted to carry a prising a mold body and mold cap and liners stop shaped to correspond to that of the extended interposed between the body and cap and definor recessed front portion of the mold'cavity to ing the length and the height of the mold cavity stop olT the length thereof, such stop being deand hence the length and thickness of the slugs tachable from the liner or otherwise removable 10 cast therein. from its operative position thereon so that the Molds of this kind have been equipped with same liner may be used interchangeably for molds plain surfaced caps for the casting of ordinary with recessed caps for casting slugs with extended flat-sided or solid slugs and with recessed caps character bearing edges or for molds with the for the casting of skeleton slugs having relatively usual plain or solid caps for casting ordinary 15 large or extended type characters thereon. Such slugs, thus avoiding the expense of carrying stocks liners may be used for determining the length of two different types of liners in all sizes. of the mold cavity and the spacing of the body In the accompanying drawing, which show the and cap of a mold for casting the ordinary solid p fer d embodi ents of t e invention: slugs which are of the smaller sizes, and the re- Fi 1 s a f o t elevation o a m d for line 20 cessed cap of a mold may be spaced from the body casting machines, provided with a liner embodythereof by inserting liners of different thicking the present invention for determining the nesses between such mold cap and body, one at length of the mold cavity; each end, and by using liners of diiferent lengths F ure 2 is a p rsp t v w of a yp ar or at one end of the mold, the length of the main slug of the skeleton form and having an extended 25 or body portion of the mold cavity may be varied.

The primary object of the present invention is Figure 9 i a View Similar 3 but Showing to provide means whereby the ordinary fiat liners the stop in inoperative position for use in ordinary commonly used for molds employing plain caps m lds for cast ng rdinary flat-sided or solid for casting solid small bodied slugs of different u V lengths may be adapted for use with recessed Similar parts are designated y h sa e refmold caps for stopping off the main portion of erence characters in the different figures. the mold cavity and also the extended or recessed The mold as shown in Figure 1 Comprises front portion thereof in which the extended usual an upper part or cap 1, a lower part or body 2 and the left hand and

right hand liners

3 and 4, respectively, which space apart the cap and body members of the mold to form the continuous casting cavity 5 which is stopped off or closed bythe inner ends 6 and. 'lof these liners. The lower or casting face of the cap 1 is formed at intervals in its length with grooves 8 which extend upwardly from the casting cavity 5 and form the ribs 9 on the body portion 10 of the slug, as shown in Figure 2, and the front of the cap is bevelled to form a recess 11 which. is extended upwardly from the cavity 5 at the front or matrix engaging edge of the mold, the extended character bearing edge 12 of the slug as shown in Figure 2 being cast in this recess.

The cap 1, however, has the recess 11 formed therein of a length suitable for the casting of a adaptor forv the ordinary liner 3, which, when applied thereto, will serve in conjunction therewith toiorm a complete closure for the respective end of the entire front of the mold cavity. In carrying out the, invention as shown in Figure 3, the ordinary fiat liner 3, which determines the length of the mold cavity, is provided near its inner end with an aperture 13, and a stopin the form, of a block 14 is provided which is beveled on one side and otherwise shaped to fit into the recess 11 in the front edge of the mold cap and to correspond in cross section with said recess, this block having a stem 15 thereon adapted to be removably inserted in the aperture 13 in the liner, so that when applied to the liner and the latter is inserted in a recessed mold as shown in Figure l, the inner end 6 of the liner will stop off or close the main portion 5 of the mold cavity and the block 14 will stop off or close the recess 11 evenly with the inner end 6 of the liner.

In the embodiment of the invention shown in Figures 5, 6 and 7, the recess 11 in the mold cap l is square or rectangular in cross section so that it will. cast a correspondingly shaped extended part 12* on the slug as shown in Figure 'Land the liner 3 is adapted to receive a block 14 of corresponding rectangular form to fit into and conform in cross section with the recess 11 the block i l having a stem 15 to removably fit into the aperture 13 in the liner 3, as in the form of the invention shown in Figure 3.

In the embodiment of the invention shown in Figures 8 and 9, the stop block 14 is of a thickness equal to the thickness of the liner. 3 and is rotatably connected thereto and fitted in a recess 3*? in the front edge of the liner by a pivot pin 3 sothat this block may be swung upwardly from the plane of the liner as shown in Figure 8 so that it, will fit into and stop oif the recess 11 in the mold cap when the liner is used in a mold having such recessed cap, and this block may be swung downwardly into the plane of the liner as shown in Figure 9, thus adapting the liner for. use in a mold having an ordinary plain or unrecessed mold cap for the casting of ordinary slugs. The block lfl may be exchanged for one of a diiferent length, for which purpose it is removable from the pivot pin 3.

In each'instance, the stop block may be used with liners of different lengths and thicknesses.

'; By providing the aperture 13 in the ordinary fiat mold liner, any shape of stop block to conform with a beveled, square or other shaped recess in the front of a recess mold cap can be employed in conjunction with such liner and thereby render the liner suitable for use in varying the length of the slugs cast in such molds. The presence of the aperture 13 in any liner obviously will not aiiect the utility or" the liner for the ordinary plain or flat surface mold cap for casting solid bodied slugs. The provision of the stop block as a liner adaptor obviates the necessity of carrying special liners for recessed mold caps, or the necessity of employing mold caps recessed to different lengths in order to secure diiierent length I slugs of the skeleton form.

I claim as my invention:-

1. A mold for line casting machines having liners for determining the length of the slug body casting portion of the mold cavity, at least one of the liners carrying a stop formed separately therefrom and corresponding inshape with a recessed front part of the mold cavity suitable for casting slugs with overhanging type faces to limit the length of said front part of the mold cavity.

. 2. A mold according to claim 1, wherein said stop is exchangeably connected to the liner.

3. A liner for determining the length of the slug casting cavity of the mold of a line casting machine, and a stop carried by said liner and corresponding in shape with the recessed front part of the cavity of a'mold for casting slugs with overhanging'type faces, said stop being adapted to occupy a position on the liner to limit the length of the recessed part of the mold cavity liners for determining the length of the slug casti ing cavity therein, one of the liners having a thickness equal to the height of the slug body casting portion of the mold cavity, and a stop carried by the liner of a shape to conform with and fit into a recessed portion at the front of the moldcavity for casting an overhanging character bearing portion on the slugs, to limit the length of said recessed portion, and removable from said position to adapt the liner to an unrecessed mold cavity.

'7. In or for a line casting machine mold, liners for determining the length of the slug casting cavity of a mold of uniform'height throughout its length, and means associated with at least one of said liners for carrying a stop formed separately therefrom, said stop corresponding in shape with a recessed part of a mold having a cavity suitable for casting slugs with overhanging type faces and said stop being operative to limit the length of the recessed part of said last mentioned mold'.

8. In or for a typographical machine, a mold having an unrecessed casting cavity, a mold having a recessed casting cavity, end liners normally operative to limit the length of said unrecessed mold cavity only, and means for rendering said liners selectively operative to limit the length of either of said mold cavities DAVID L.
