To all whom it may concern: 7 Be it knowni bllat BENJAMl-N F. L'BELLQWs,

and useful Improvements in Slug-Ejecting Mechanism for Line-Casting .Machines, of which the follow-ing is a specification. I

This invention is intended for use as part of aline castingtypographic machine y that isto-say, a machine-by whichtypeiloars or slugs a'recast in a: mold slot Whose :front face is closed by an: assembled line of matrices. V L In machines" of this character the type bars are 'pu'shed out of the mold slot andl between trimming knives by an ejector blade which engages'that edge; of the type bar or slug which is the bottom-edgewhen the slug is in use; I V I Machines of this "sortare adapted to use an'd do'usemolds having slots of different:

sizes.1It-ispractically necessary that the ejector blade I shall pretty nearly; fill the mold slot as it'pushe's the typebarout. It

isfurther necessary 'to use, from time to time, avarietyof ejector bladesawhioh mustf vary as to width, andmaywvary asto thicknessyso that the ejector in' use shallalways correspond with the dimensions-=ofthe slot of the mold in use.

T heobjectof thisin'vention is to provide in a machine of-thissor'ta plurality of one piece ejectors having blades suitable for: use

at different times "and: with difierent molds, together; with means whereby .any ejector, blade may be readily brought into operative relation with the mold and with the mechanism by which the selected ejector-blade may be operated. I p

The invention consists in thecombination of parts shown in the drawing and hereinafter described and pointed out defi nitely in the appended claims.

In the drawing, Figure 1 is a front elevation of a mold disk and the ejector mechanism behind it,the mold which will be in the ejecting position having been removed from the mold disk; Fig. 2 is a side elevation of the present invention and some associated parts; Fig. 3 is a side elevation, and Fig. 4

is a front view of the ejector operating slide. Fig. 5 is a side elevation of an ejector and RQ ea 1a a 1e a ar: rat 'nteanec: 18.1191 7.-

diski as shownxin Figz l'isrin the casting H position," that is to say l-infthe positionto} haye'the-front side ofthei mold slot -a closed loy a:v line Jofmatrices', and-- to: have molten? metal injecte'd into its rear side. The mold which fitsninr and oventhe hole'al in the; mold'di'skustftogthe left of the upper mold intFigz 1 would be in the -ej'ecting posi-tion, that =i s, ='the position it' would occupy in order that the to-be-described ejector mechanism may slot. V

The mold diskmay beturned by'any suitable mechanism, 1 which has-nothing vtoi do push a' slug-forvvard outof the *mold with the presentinventi'on; and -the mold disk may be adapted for adj ustme'nt' 'so' t-h'at any one of the molds'securedthereto, in the ordinary operation; of-the machine; will be move'd back and forth between the T casting and ejecting-positions,- as; described. The

mold disk-as shown carries-five molds,- but it -mi ghtcar r-y any desired number and the mold slots-:01 the several molds maybeof various sizes dependinguponthe character of the Workwhich the, machine is'-' tempo-- rarily equipped for doing; Because-the mold" disk" carries five molds as shown, it-is desirable that there-should be fiveejector's B each fitted to ootiperatewith one of these molds".

Inthe constr'uction shown five F of -such ej ea tors "are showm -and tl eyare'slidably mounted in an ej ect'o'ri magazine D which is pi v fi otally suspended from -the shaft F," which may be a shaft having other functions, or a shaft especially provided for" the purpose. Each ejector comprises a body I; (and all of these bodies are preferably the same size) and a blade I) which is preferably formed integrally with the body, and projects forward therefrom. All of these blades are of the same length, but they vary in idth and may vary in thickness, as required. Some may be narrower than the body, one the same width, and one or more may bewider.

top and bottom edges, and these are slidably mounted in guide grooves d in the upper and lower members of the ejector magazine. These ejectors, when so mounted, occupy nearly parallel positions, although they actually occupy positions which are radial with respect to the axis about which said magazine may swing.

The ejector magazine may be swung into positions to bring any desired blade into operative relation, that is to say, into alinement with the slot of that mold which is in the ejecting position. To so move the magazine a rocking sleeve G is mounted in suitable fixed bearings concentrically with the shaft F. This sleeve, at its rear end, is formed with an arm 9 that is pinned to the frame (F of the ejector magazine, whereby the magazine must rock with. said sleeve. This sleeve also carries a handle 9 by which it may be rocked; and is provided with a downwardly extended arm 9 having near its lower end a hole through which the index pin K may pass. This arm 9 passes between two parts a a of the fixed frame of the machine, and in these parts are five index holes 02 By putting the index pin in the proper holes a a, and through the hole in the arm 9 the ejector magazine will be fixed in the desired position.

When any ejector is in operative relation with the mold, it is likewise in operative relation with the ejector operating slide M. This is mounted in dovetailed guideways so as to be movable forward and backward; and is associated with suitable mechanism, which may be substantiallylike that shown in Letters Patent No. 1,080,570. A part only of the mechanism shown in that patent is shown in Fig. 2 of the drawing of this application, viz., a lever P having a pin 79 at its upper end; and a hook R which is pivoted to the slide M and engages said pin. The lever P is positively rocked backward and forward, thereby moving said slide, by two cams T T with which two arms 7) p respectively engage. A plate m which projects forwardfrom and is rigidly fastened to the slide M has a T-shaped tenon m which may easily enter a T-shaped mortise Z1 in the rear end of the body part of each ejector. This slide M is so placed that said T-shaped tenon 122. will be in the notch 6 of that one of the ejectors which is in operative position. This comes about in part from the location of said slide, and in part because, as the ejector magazine is swung about its pivotal support, the T-shaped cross mortises in the several ejectors go'over said T-shaped tenon, wherefore, when the ejector magazine stops and is fixed in position, the T-shaped tenon m is in the T-shaped mortise of that ejector which is in operative position with respect to the mold.

Having described the said invention, I claim: I

l. Ejector mechanism for typographic machines comprising, in combination, a mold, ejector operating mechanism which includes a guided slide adapted'to engage with any ejector which is brought into alinement with it, a pivoted ejector magazine located between said mold and ejector operating slide, a series of ejectors slidably mounted in said magazine,said magazine being capable of swinging to bring any ejector therein into operative relation with the mold and with the ejector operating slide.

2. Ejector mechanism for typographic machines comprising, in combination, a mold, ejector operating mechanism which includes a guided slide adapted to engage with any ejector which is brought into alinement with it, a pivoted ejector magazine located between said mold and ejector operating slide, a series of ejectors slidably mounted in said magazine,-said magazine being capable of swinging to bring any ejector therein into operative relation with the mold and with the ejector operating slide, and means for locking said magazine in any operative position.

3. A slug ejecting mechanism for linotype machines having a plurality of ejectors mounted on a common axis and adapted to selectively cooperate with the mold disk.

In testimony whereof, I hereunto atfix my signature in the presence of two witnesses.
