MOLD FOR TYPOGRAPHICAL LINE-CASTING MACHINES.

Application filed June 23,1925, Serial No. 38,999, and. in Great Britain July 1'7, 192%.

ber of special length liners and filling-up pieces varying according to the measures or lengths of slug to be cast.

In a mold constructed according to the present invention, the mold body and mold cap are both of the ordinary construction adapted to cast slugs of full measure, and the means by which this mold is rendered capable of producing at each cast, a number 0t slugs of shorter measure is a member which combines in one entity the sectional liners and filling-up pieces, and fulfils the functions of both.

The invention Will be described with ret crence to the accompanying drawings, in

which:-

Figures 1 and 2 are respectively a plan and elevation of a liner according to the present invention 3 "re 3 a sectional view of the same taken on the line 3-3 of Figure 1;

Figure at is a similar sectional view taken on the line of Figure 1, and

Figure 5 isan elevatioinot a mold showing the improved liner in position.

The atoresaid member, combining in one entity sectional liners and filling-up pieces, herein referred to as a liner, is designated by the reference numeral 1. The liner 1 is flat on its upper side where it is held in position by the mold cap 2, which contacts with that side practically throughout, and at its underside near its ends it is provided with the usual locating ribs 3, which enter grooves 1 in the mold body 5.

V The liner 1 is of the full length of the mold and on its underside, at the parts corresponding with the sections to be cast, is milled or otherwise reduced in thickness, :torming intervening ribs 6 extending across the liner in fore-and-aft direction and adapted to completely close the space between the mold body 5 and mold cap 2. The 't'rontends of these ribs 6, as of the ribs heretofore provided for the same purpose, terminate slightly to the rear of the front of the mold, so as to leave each pair oi adjacent short measure slugs connected by a thin web or neck of metal which permits oi the complete casting to be ejected from the mold as a single entity and the short measure slugs afterwards to be readily separated from each other.

The underside of the liner 1 is also formed with flutes or grooves 7 for forming the known ribs on one side of the slugs, and these grooves 7 "are flared at the face of the liner, as indicated at 8, whereby projections are formed at the corresponding parts oi the slug sections, which projections serve to prevent blank sect-ions being withdrawn from the mold by the metal pot mouthpiece when the latter is drawn backfrom the mold after the cast is made.

It will now be understood that when the liner 1, according to the present invention, is secured in position between the mold cap 2 and mold body 5, as illustrated in Figure 5, cells or cavities 9 are formed, wherein the different sections or short measure slugs are cast. The dimensions of these cells in diliferent liners vary according to the measure and body dimension of the slugs to be produced, and in any case a change, or the setting of the mold for sectional work, requires only the use oi? a single liner which can be applied to a mold of ordinary con struction.

Having described my invention, I declare that what I claim and desire to secure by Letters Patentis 1. In a mold for a typographical line cast ing machine, the combination with a mold body and mold cap, of a one piece liner independent, and extending the full length, of said body and cap, means rigidly securing together the cap, body and liner with no the last-named element between. the two first named, said liner being formed intermediate its ends with at least one rib integral therewith and dividing the mold cavity into a plurality of sections.

2. In a mold for a typographical line casting machine, the combination with a mold body and mold cap, of a one piece liner independent, and extending the full length, of

said body and cap, means rigidly securing no together the cap, body and liner with the last-named element between the two first named, said liner being formed intermediate its ends With at least one rib extending transversely of the liners casting face and integral therewith and terminating slightly to the rear of the front of the mold so as to produce in the iuoldcavity a plurality 01. cast slug sections each connected to a neigln bouring slug by a thin web or neck of metal.

3. In a mold for a typographical line castingmachine, thecombination with a mold body and mold cap, of a one piece liner lDClQ- pendent. and extending the full length, of said body and cap, means rigidly securing together the cap, body and liner with the last-nal'iied element between the two first named, the mold cap contacting with the liner throughout its outer surface, and a plurality of recesses in the inner surface of the liner each separated from its neighbour bye rib extending transversely of the liner and integral therewith and contacting with the castingface ofthe mold body.

4. In or for a typographical line casting machine, a. slug casting mold comprising a mold body, a mold cap, a detachable oncpicce liner therehetween, and means rigidly securing said parts together in casting relation, the said one-piece liner defining the end walls and one of the side walls of the mold cavity and formed intermediate 1' ts end walls with at least one ril'rintcgral therewith and dividing the mold cavity into a plurality of casting sections, A

In testimony whereof I have affixed my signature hereto.

TOM DRAKE.
