To all whom it may concern:

Be it known that 1, JOHN R. Roenns, of the borough of Brooklyn, county of Kings, and State of New York, have invent-ed a new and useful Improvement in Ejecting Devices for Line-Casting Machines, 810., of which the following is a specification.

My invention relates to machines in which printing slugs or bars are cast in a slotted mold and delivered therefrom by an ejector blade advancing from the rear against the edge of the slug. In all these machines the molds are variable or adjustable in length, to produce slugs for printing columns or pages of different width.-

The object of my invention is to provide a composite-ejector with its parts so constructed and combined that its operative portion may be instantly varied in Width to correspond with any change in the length of the mold slot. To this end I construct my ejector blade of a series of parallel longh tudinal sections arranged edge to edge, and I provide in connection with their actuating slide, locking mechanismby which any de sired number of sections or blades can be from buckling or bending under the thrust ing strains to which they are subjected in action. I also provide means by which-the sections may be instantly thrown into and.

out of action by the operator in front of the i machine.

and for casting two or more short slugs atone time, but also to all other machines of the same general character.

I have limited the drawings herein to those parts immediately associated with my construction. A

the mold wheel and the forward end of the supporting slide being broken away to erpose the other parts to-view. Fig. 3 is a view of the same general character as Fig.

2, but with portions broken away to show the internal construction.-

a is a perspective view illustrating thesectional con struction of the ejector. Fig; 5 is a front elevation of a' portion orthe frontend of the mold slide showingariother mode of Referring to the drawings, Arepresents the vertical'mold disk or wheel having the usual slot-ted mold, B, secured thereon. -This mold may be of the constructionshownin Letters Patent of the United States No. 620,804, or of any other construction which will admit of its slot or cell being changed in length at will, variousconstructions to this end being well known in the art.

C is a horizontal reciprocating slide mounted in the frame of the machlne and having at the forward end a transverse arm,

for the purpose of advancing the mold against the matrix line and retracting it,

together with the contained slug, therefrom, subsequent to the casting action.

D is the ejector slide carried by, and arranged to reciprocate horizontally on, the mold slide, 0, as usual, for the purpose of actuating the ejector. Ordinarily the ejector consists of a single blade secured to the for-. ward end ofthe slide D and arranged to be projected forward by the latter through the mold to drive the slug therefrom.

E represents the ejector proper. Instead of being made in a single piece or bladeas heretofore, I construct it of a series of parallel blades sections, or fingers, 6, each having a vertical width of two ems, more or one "above another, and if the machine is adapted to cast a single, continuous sing, the blades have their edges arranged in can tact, as shown in Figs, 2 and 4:; whereby they are adapted to sustain and guide one the series of blades or sections, is guided between the vertical face of the mold slide, C, 'on one side, and the vertical platen, secured to the mold slide, on the opposite side of the ejector. As clearly shown in the sev-' eral figures, each of the ejector sections or fingers, e, ,i: supportedand guided on both sides from one end to the other. In practice the blades are commonly made -very thin, in order. that they may enter a'mold roducing thin slugs, or slu sjwith thin 'odies. These slugs frequenty 'oiier substantial' resistance to the advance of the ejector blades,.and as heretofore supported 'and guided the thin blades were liable-to bend or buckle midway of, their length. The resent construction admits at very thin b ades being used, and gives them such firm support from their rear end to the point w ere they enter the mold, that there is no possibility of their being sprung or bent. The several sections of the ejector are free to slide forward and backwar'd independently, sothat any desired number of form an (ejector o a vertical width corresponding to' the length of theslug which is being'at the time cast in the machine, while the other sections are permitted to remain inactive, in the inner or backwardposition. v The ejector sections,- e, are each actuated by a horizontal slide, G. These slidesons connectedr to each section at the forward end-Fare mounte f grooves, 0. formed on themold slide 0. n is tobe noted that'the intermediate slides G which connect the ejector blades 6 with the imain'actuating slide Care'of less width vertically than the blades and also that'these slides G lie"horizontally-to one side of the blades and the slide D, .This construction admits of each blade bearin throu hout its length on'one side against as fixed plate Oand on the opposite side against tl e 'fi'xedplate F. In

them may be brought into action jointly tov be equally thin. When the plates are su ported as above described, they may be ma e of the requisite thinness without danger of theirbeing sprung or bent out of shape if, as often happens, the slug ofli'ers substantial resistance. The essence of the invention in this regard lies in giving su port to the 55 blades on both sides at points etween' their another. Theentire ejector, that is to say this manner the blades" e are supported and ends, preferably throughout the whole or the, greater part of their length.

In order' that any required number of the sections 0, may be coupled to" the actuating sllde D while the other sections remain free, I mount on the ejector slide D a vertically slidmg bar I-I, having its lower end arranged to travel forward and backward'on a rodI, attached to'a vertical slide J, the latter belng mounted in the mold slide C and connected by an elbow lever, K, mounted on saidslide and actuated by a rod L extending forward, throu h a suitable guide arm, to the front of the machine. The slide ll is arranged to rise and fall behind the slides Gr, attached to the ejector sections. It may be moved upward and downward by means of the rod L to such position that it will act behind and drive forward any desired number of sections withoutaffecting the otherswhich will remain at rest. The retraction of the operative sections is afiected by means of shoulders, on the rear ends of the slides G, enga ing ehind the vertical shoulder d on the e ector slide, D. The rod L is preferably'provlded as shown with a series of graduations representing ems or points, to be read in connection with a pointer l,,so that an operator desiring to adjust, the ejector for a mold of a given length has only to move the rod L until the corresponding number thereon registers with the pointer.

When the slot is provided with a mold having two or more cells or slots, for cast- 10o ,ing two or' more short slugs one time, the ejector sections instead'oi being in contact at their edges will be separated to correspend with the position of themold cells have guiding groovesthereon to receive the ejector sections, as shown in- Fig. 5.

It is manifest that-in place of the bar H and-slides G any other appropriate means may used for connecting the ejector sections with the actuating slide.

It will be understood that both the ejector slide and. the mold slide may be operated by the usual mechanism or by anyother suitable means. f n

The sections, 0, of the ejector are pref erably connected-to the slides G by providing them with holes to receive the tongues,- g, projecting laterally from the sides as shown in Fig. 4. I

It will be observed that the ejector sections or fingers, e, may be disconnected at will from the slides G, and fingers of other widths applied thereto, corres ondin w1th the cells or openings in the mo (1 who may 125 be used.= This construction admlts of the fingers e being changed in number and size, and of their being s aced apart any required distance, in or er that they may be or slots, and in such case the plate F will 105.

ating slides, G, of a width less'than the' blades, and means for operating one or more of'the slides-G at will; whereby the ejector is adapted for'change in width at will; and its fingers supported in such manner that they are prevented from bending.

2. In 'a line casting machine, a series of reciprocating ejector fingers or sections, 6, and a main 'slide'for actuating the fingers, a series of intermediate connecting slides,

G, of less vertical width than the ejectors,

a grooved plate, C, sustaining the slides G and bearing against the ejectorv fingers, a stationary guide, F, bearing against the ejector fingers on the opposite side, and

means forconnecting one or more of the slides G with the main slide D at will.

3. In combination with the ejector sections, 2, slides G, the actuating slide D, the vertical connecting slide, H, the" lever K for adjusting the same, and an actuatin handle extending from said lever t'o -the rout of the machine.

4. In combinatiom'an ejector comprising a series of parallel fingers or sections, means for actuating the series, means ,for connecting any desired number of-the sections at will with the actuating means, and an in: dicator cooperating with the connecting means; whereby the attendant is enabled to adjust the ejector instantly for delivering slugs of any given length.

5. In a line casting machine an ejector comprising a series of sections or fingers e, means for guiding the same on both sides, throughout their length, slides G and guides therefor, an actuating slide D, and means for connecting the last named slide with one or more of the slides G at will.

6. In a line casting machine, the combination of a plurality of slides G, means for reciprocating said slides, ejector blades 6,

connected to the respective slides, and supporting guides located on -opposite sides of the ejectors and extending substantially their entire length. I

7. In an ejector mechanism, the combination of an ejector finger e, an actuating slide G therefor, a slotted guide for the slide G, and guides lying against both sides of the finger e for substantially its entire length.

8. In an ejector mechanism, a'serics 01 ejector fingers or sections 6, and means for guiding and supporting the same on both sides throughout their length; a corresponding series of slides, G, with distinct means for guiding the same; and means for Open ating any number of the slides G in unison.

9. In a line casting machine, the combination of the mold wheel A, the mold B thereon, the mold supporting slide C, the series of ejector sections, the series of slides, G, connected thereto, a slide, D, adapted to actuate the lastnamed slides, and adjustable ,means forconnecting the slide D with any desired number of the ejector slides G.

10. An ejector mechanism for a line casts ing machine, comprising an actuating slide, a series of ejector fingers lying edge to edge, intermediate slides connecting the ejector fingers with the actuating slide, intermediate slides'connecting the main slide and the ejector fingers and lyin to one side of the same, and two fixed guides lying against opposite sides of the ejector "fingers, one of said guides grooved to receive the intermediate slides, as described and shown.

In testimony whereof I hereunto set my .hand this fifteenth day of January, 1909,

in the presence of two attesting witnesses. JOHN R. ROGERS.
