MDLDIN'G MEANS FOR TYPE-CASTING- MACHINES AND THE LIKE.

Application filed August 28, 1924 Serial No. a06,539.

My invention relates to type molding means for type casting machines and the like and is concerned particularly with the provision of an improved liner for association therewith.

Liners of this general description are positioned between the base and cap members of the mold, between which and the opposed ends of the liners a fused or molten metal is run into a line of assembled matrices to produce a cast, slug or type line. The slug is then ejected by an ejector blade, projected into engagement with the inner edge of the slug or cast and thence through the space bounded by the opposed faces of the mold base and cap and the opposed ends of the liners. lln that proper positioning of the liners is essential because a distorted cast will be the result of any discrepancy, suitable cooperative engagement between the liner and mold is provided for properly positioning the liner laterally and longitudinally therein. Frequently, the ejector blade is of greater width than the space between the liners or is so positioned through failure to change or adjust the width or positioning of the blade to conform to a change in length of the slug as the blade is projected to eject slugsof various lengths that upon projection of the blade the liner is engaged with the result that either the shank of the liner or the cooperative positioning connection between the liner and the mold is distorted or the projecting lip at the corner of the liner for positioning the adjacent edge of the cast is broken off. Heretofore, in either event, it has been necessary to replace the distorted liner with an entirely new one. This has occasioned considerable expense in that the liners with their positioning means for engagement with the mold are quite expensive.

It is the object of my invention to provide a simple, effective, inexpensive and improved. liner comprising a head portion having positioning means for engagement with the mold and an inexpensive shank portion having jointed connection with the head portion, of such formation that any distortion will be confined to the shank por tion of the liner the replacement of which shank portion in connection with the same head portion is far less expensive than is replacement of the entire liner as has been necessary heretofore. The features of my invention are, therefore, that I provide a two-piece liner and that I confine any distor-tion to the less expensive of the two pieces. The particular formation shown for accomplishing these features is, of course, subject to modification, the one illustrated showin; a type which I have found to be satisfactory.

I still further aim to provide shank portions of various lengths for use with a single head portion whereby slugs or type lines of various lengths may be had by replacing the shank portion of the liner with a shank portion of the desired length. A. set of inexpensive liner shanks of various lengths thereby supplants the set of complete liners (each having positioning means for engagement with the mold) of the prior art. it further feature of the invention is that the utility of the shank portions of the liner may be increased by shortening the distorted shanks and using them again.

These and other features of my invention will appear from the following detailed description and the claims taken with an. inspection of the accompanying drawings which illustrate a particular embodiment of my invention.

Referring to the drawings:

Figure 1 is a front elevational view of the mold disk of a linotype machine, showing the type molds clamped in place;

Figure .2 is a plan view of the base n1em ber of a type mold (taken substantially on the line 2-2 of Figure 1) showing a liner embodying my invention positioned thereupon;

Figures and t are perspective views of the shanlr and head. portions respectively of the liner shown in. Figure 2; and

Figure 5 is a longitudinal sectional view of a modification.

Referring to the drawings, the mold disk 1 is provided with the usual openings in which the type molds 2 are mounted. The disk 1 may be rotated in the usual or any preferred mamuer as through an annular gear 3 encircling the periphery thereof and secured thereto.

The molds 2 comprise base members -il attached as through suitable bolts 5 to the mold disk l. Posts 6 projecting upwardly from the opposite ends of the base member (Figure 2) engage in cooperating grooves (not shown) in the associated cap members ill) 7 assuring proper relative positioning there between. With the liners arranged between the opposed faces of the base member and the cooperating cap member 7 of the mold as will be hereinafter described, the cap member is clamped securely in place by means of set screws 8 (Figure 1) threaded through the mold disk 1 and into engagement with the arcuate edge of the cap member.

Thelinerwith which this invention is particularly concerned comprisesa relatively short head portion 9 and a cooperating shank portion 10. The under surface of the head portion 9' is provided with a transverse ridge 11 adapted for cooperation with a groove l2 provided transversely across the upper face of the base member l of the mold to position and maintainthe proper longitudinal positioning of the liner. In addition to t groove and ridge engagement between the mold and liner head 9, the head 9 is provided with a transverse slot'll tor cooperation with a short pin 14 extending upwardly from the upper surface of the base member 4, limiting the transverse movement of the liner head across the upper face of the base member of the'mold and assuring proper lateral positioning of the liner.

W The outer end of the shank portion it) of the liner is mortiseclas shown at 15 for the reception of the adjacent tenoned end 16 oil the liner head 9. Thus the head and shank portions of the liner are joined in such manner that separation is impossible, except by relativemovement in the direction of their thickness. The opposite end of the shank portion 10 of the liner is provided with a projecting lip 18 for positioning the adjacent edge of the cast or slug, as well understood by those skilled in the art. The lip 18 at the same time notches the corner of the slug to prevent the formation ot a bur. The usual liner 19 is positioned adjacent the opposite end of the upper face of the base member 4: of the mold through cooperating ridge and groove and slot and pin or other suitable engagement. A two-piece liner of the type with which my invention is concerned might, even be provided at this end of the mold under certain conditions.

Upon arranging the liner between the base and cap members of the, mold, the mold is secured to the mold disk 1 as hereinbetoro 'set out. A line of matrices is then assembled asv well understood. by those skilled in the art, whereupon the fused or molten metal is run between the base and cap members and the opposed ends of the shank portion 10 ciated with the machine into engagement with the inner edge of the slug or cast 20 produced, forcing the same out through the space bounded by the mold base and cup in the artis thus ell'ectively prevented. The liner head 9 carrying the liner po ennui means never damaged, the tllSLOl'tlUll confined to the shank it). It the prong is broken oil, a new shank is replaced in connection with the same head at a slight cxpense. it the prong is simply bent bar-k a shown, it might be even bent back into place and the shank portion of the liner uscd again, subsequent engagement the cjcctor blade in all probability resulting in complete rupture oi the prong.

By providing suank portions l0 o't various lengths for use with the same head portion 9, slugs or type lines of various lengths may be had by replacing the shank portion with a shank portion oi the desired length. A. sci of inexpensive liner shanks of various lengths thereby supplant the set oi complete liners of the prior art.

Upon rupturing or breaking oil the moct-ised end of the shank 10, the end can be easily evened oil and mortised for further use when a shorter liner is desired in producing a type line of greater length.

The particular jointed connection between the head and shank portions of the liner shown is, of course, subject to modification, the essential l'cature being that the jointed connection is such that any distortion is conlined to the less expensive of the two liner pieces.

ln the modification shown in Figure 5, the cooperating edges of the mortised and tenoned ends respectively of the head and shank portions 9 and 10 ot the liner are beveled as shown at 25. The tenoncd end of the head 9 is arranged within the mortiscd end of the shank 10 whereupon the cooperating beveled edges are forced sc curely into engagement. Thus while in eliect a solid one piece liner is thereby produced any distortion will still be confined to the shank portion .10 substantially as set out in connection with Figures 3 and l. A. distorted shank is readily replaced with another shank forced into engagement with the beveled edge of the mortiscd cud oi the head 9.

I contemplate confining any distortion to the shank portion of the liner by weakening the same at a point other than at the jointed connection with the head portion.

I claim:

1. A liner, comprising a relatively expensive head having a transverse slot for engagement with the mold pin and a transverse rib for engagement with the mold groove, a relatively inexpensive shank having one end defining one end of the mold space, said shank being formed independent of the type metal, and of substantially the same thickness as said head to form a substantially uniform mold opening from the space defining end of the shank to the free end of the liner head, and a joint connecting the head and the shank of the liner, said joint permitting replacement of the shank and continueduse of the head with new shanks and the cross sectional area of the shank adjacent the joint being less than the adjacent cross sectional area of the head to Weaken the shank at the joint so that the shank will rupture first to preserve the head upon engagement of the liner by an ejector.

2. A liner comprising a relatively expensi \e head having a transverse slot flOl engagement with the mold pin and a transverse rib for engagement with the mold groove, a relatively inexpensive shank having one end defining one end of the mold space,

said shank being formed independent of the type metal and of substantially the same thickness as said head to form a substantially uniiorm mold opening from the space defining end o'l the shank to the free end of the liner head, and a joint connecting the head and shank of the liner, said joint comprising a dove-tail tenon on the head and a cooperating dovetail mortise in the adjacent end of the shank, said mortise extending into close proximitiy to the opposite side edges of the shank to weaken the same so that the liner shank will rupture first to preserve the head upon engagement of the liner by an ejector.

A liner comprising a head having positioning means tor engagement with a mold and a supplementary shank, a joint connecting said shank and head, said joint permitting replacement of the shank and continued use of said head with new shanks, said head and shank being of substantially the same thickness and the cross sectional area of the shank adjacent the joint being less than the adjacent cross sectional area of the head to weaken the shank at the joint so that the shank will rupture iirst to preserve the head upon engagement of the liner by an ejector.

ln witness whereof I hereunto subscribe by name this 25th day of August, 1920.
