To all whom tmay-ooiwem:

Beitknown thatI', AUGUSTUS A. BALL, Jr acit-izen of the IJnited States, and a resi: dent of Bronklyn' county of Kings, and Stateof- New York, have invented a new and,;usefnl Improvement in Typographical OflSiiIng hi lChlIleS,;Of which the following is a specification..-

My invention has r-e'ference to typographical casting machines, such for instance as linotypemachines; wherein a slug or bar is cast in a slotted moldagalnst a composed line of matrices,- -wh;ich ispresented tempo:

rarily to the front the mold and serves to form the type characters on the edge of the slug. In this class of machines, as represented for example in U. S. Letters Patent to O. Mergenthaler, No. 436,532, the slug is delivered from the mold by an ejector blade, which advances from the rear and moves the slug before it out of the mold and into a receiving galley.

In order to adapt the machine for producing slugs of different lengths, the mold slot is made variable in lengthby the use of interchangeable filling pieces or liners, such as are shown for instance in U. S. Letters Patent to G. A. Bates, No. 618,554. When the length. of the mold slot is thus changed, the ejector should be also changed, and this is effected by detachingit and substituting another of a width corresponding to the new length of the slot. v

In practice it occasionally happens that an attendant, through ignorance or carelessness, will substitute a wide ejector without inserting a short liner, or that he will insert a long liner without changing the ejector. In such case, when the ejector advances, it will contact with the inner end of theliner and drive it-forward. As the liner is ordinarily providedwith a transverse rib which is seated in a groove in the mold body, the result will be the breakageofthe expensive mold, due to the strength of the liner and the great leverage exerted thereby under such 'condit ions.

The aim of my invention is to prevent accidents of this character, and this is effected. by the provision of a member which is adapted to yield in the event of undue strain thereon. Preferably, the liner is the member selected for such improvement, and more specifically the result is secured by lessening its resistance, so that it will be moved or TYPOGRAP ICAL CASTING-MACHINE Specification of Letters .I'atent.

bent by the advancingfjector jwith ut ii! jury to the more expensive mold; orjt qth ejector blade. I I

I have herein shown mv; invention as ;ap

plied by way ofexan plei n-a preferred form, and'obviously many changes and variations may be made therein without. departingfrom its spirit. I I therefore desire ;-it to be. disin so far as such limitations are specified in tinctly understood that I do not limit myself to any specific form or embodiment except perspective view of a mOld-havinginy ins vention applied thereto Fig:. 2 is a perspec-' tive view of the liner detached;Fig. 3' is a top plan view of the niold-with the cap .de: tached and illustrates the?manner infiwhich an ejector of too great width acts uponthc yielding liner.

Referring to the drawing, the mold consists of the body portion A, the cap B secured thereto, and liners interposed between the body and cap, whereby the slot D may be regulated both as to length and height, in the manner well understood in the art and as substantially illustrated in the Bates patent previously mentioned. In order to prevent the breakage or bendingof the eXpen-- 'sive mold or of the ejector blade E, in the event that the latter is too wide to pass through the inold slot D, I provide a yielding member, which in the specific example shown is the liner C. This liner in most respects is substantially the same as the one illustrated in the Bates patent, it being formed with a slot C and with a transverse rib G which latter engages'in a corresponding groove in the mold body. This rib serves as a means for determining the longitudinal adjustment of the liner and also for preventing the liner from turning or twisting horizontally. If therefore the ejector blade E.

be too wide'to pass through the mold slot I), and therefore contacts with the liner, ordinarily and due 'to the strength of the latter and the considerable leverage exerted there-- by, the mold itself will. be deformed or broken. It is therefore preferable to form the liner so that it will yield and be bent in the event of undue strain being imparted thereto, and this result I secure by recessing it, as at C, at a pointinside of the rib C .to provide an integral and permanently weakened portion which is yieldable in the event that suflicient pressure be exerted on an edge'ot the liner.

The operation of the" parts is clearly shown in FigaB, it being noted that the ad vanceof the ejector blade E acts merely to bend the liner, instead of allowing the latter to eXert'its destructive leverage upon the mold in the manner previously indicated. It should be. noted that thisweakening or recessin-g of the liner .does not otherwise afiect its, functions, as at the rear side thereof it presents a continuous surface of the ordinary extent and ofsufiicient strength to close tightly any 'holes in the potmouth which may lie behind it. v

- ,As before indicated, he broad idea of the. invention .is' the provision ofa yielding '-'*member for the purposes specified, and obviously its selection, location and construction may be va'ried in many-ways that will suggest themselves to those skilled in the art. Having thus described my invention, its construction and mode of operation, what'I claim and'desire to secure by Letters Patent of the United States is as'follows:

I 1. A mold liner consisting of an integral structure formed ,of fracturable material and having in oneedge a permanent recess extending inwardly toward the opposite,

liner is engaged by an ejector, said liner being provided with'a-transverse rib at one side of and adjacent the recess.

- 3.. In a typographical casting machine, the mold comprising a body portion, a cap, and a mold liner consisting of an integral structure formed of fracturable material and having in one edge a permanent recess extending inwardly toward the opposite edge, thereby providing a permanent reducedportion which is yieldable Whenever the liner is engaged by an ejector.

'In testimony whereof I hereunto. setmy hand this 13th day of December, 1911, in the presence of two attesting witnesses.
