Application ile April 15, 1909. Serial lo. 496,052.

To all whom it may concern:

Be it known that I, Win'roii G. Mmmm- ToN, of the city of Oakland, county of Ala meda, and State of California, have in# vented a new and useful Improvement in Linelasting Machines, die., of which the following is a specification.

My invention relates to line casting niachines of the general cliaracterrepresented in Letters Patent of the United States 436,532, for producing printing bars or slugs, each bearing the type characters to print a line. In these machines a composed line of matrices representing the characters to appear on one slug is-presented temporarily to the face of a slotted mold, which is mechanically filled with molten type metal, which solidiiies in the form of a slug or bar, having e the characters formed by the matrices. i fter the casting action the disk is turned to present the mold opposite a vertical horizontal ejector blade, which advances horizontally through the mold, driving the upright slug therefrom into a receiving galley at the front. It is a common practice to provide these meld wheels with two or more molds the slots in which differ in size, so that either mold may be brought into action at will for the production of the slugs required, the change from one mold to the other being accompanied by a corresponding change or substitution of ejector blades..

The object of my invention is to ada t the machine to produce at will slugs of diiierent lengths without the necessity for changing the ejector blade, the one blade being adapted to deliver both long and short slugs. To this end I provide the rotary mold wheel with two alternately usable molds having slots of equal length, one of the slots being divided by a partition in order that it may produce two short slugs. In connection with these t'wo molds I use an ejector slotted or divided in such manner as to straddle the partition and deliver from the divided mold the two short slugs formed therein. The same blade will deliver the long slugs from the continuous mold. I also provide means whereby the two short slugs formed inthe respective ends of the one mold are separated and delivered to different points.

The mold stands in a vertical position while the slug is being delivered.

With the exception of the parts hereinafter described the machine may be in all respects of ordinary construction.

In the drawings: Figure 1 is a horizontal section through the `casting and ejecting` mechanism of a Mergenthal-er machine with my improvements incorporated therein. Fig. 2 eis a front-elevation of the mold disk and molds. Fig. 3 is a section on the line 3-3 Fig.- 1. ig. 4 is a side elevation `of the parts shown in Fig. 1. Fig. 5 is a side view of the ejector blade.

Referring to the drawings, A represents the vertical mold wheel or disk journaled to a horizontal supporting slide, B.

C, C represent the two slotted molds mounted on opposite sides of the disln'so that the rotation of the latter will serve to present either mold in operative relation to the other parts as usual.

The mold C has a continuous slot fromeiid to end, and is `adapted for the production of long slugs. The mold C" is divided by a partition, c, into two sections, adapted' to produce short slugsone or both of which may be used. The molds may be constructed and the partitions inserted and secured in any appropriate manner.

D represents the horizontal ejector blade by which the slugs are driven forward out of the molds. This blade is made of suiiicient width to fill or substantially ll the 'long mold, in order to eject long slugs there- Instead of being made in one solid from. piece as usual, it is divided or slotted longitudinally in such manner as to straddle the partition c. It will be seen, therefore, that the one blade will serve to eject the single long slug from one mold, or the two shorter slugs from the divided mold, as required.

E, E are the two knives between which the slugs are delivered when ejected from the mold.

F is the galley in which the slugs are received. The galley is in position to receive all the long slugs and the lower one of the short slugs directly from the mold.

G is a spring pressed plate forming one side of the throat through which the slugs y ass, between the knives and the galley.V

his plate instead of being made continuous as usual is recessed or cut away on one side at the upper part als shown at g in Fig. Li, the opening being of such size and so located that while the slugs delivered from the lower a'rt of the divided mold will be held by the lade and continued in their course to the' alley, the slugs cast in the upper part of yt e mold will be compelled to escape laterally through the opening g. In order to secure this delivery the sprin g is seated in the throat or passage as slgiown to act against the upper slugs and deect them. A chute or .guide plate g2 may be used to direct them downward to a galley or receptacle 7% any kind.

ile I have shown a slotted ejector blade it is to be understood that a blade composed of two or more independent sections may be used, these sections to be adjustably or detachably connected` with the operating slide in any suitable form, various connections suitable for the purpose being known in the art. v

Having described my invention, what I claim is:

Vl. In a line casting machine, a rotary' wheel provided with two alternately operative molds of equal length, one divided and `the other undivided, in combination with a divided ejector adapted to enter both molds, a receiving galley in position to receive both long and short slugs, and means for directing one short slug of each pair away from the galley.

v 2. In a line casting machine, a mold wheel provided with two alternatelv usable molds, one having a continuous and the other a dil vided slot, in combination with a divided ejector adapted to enterboth molds, and means for separatin the two slugs delivered from the divide mold.

tion of two alternately usable molds, one' continuous and the other divided in length,

an ejector adapted to pass through both molds, a galley adapted to receive the long slugs, and also the 'lower short slugs means for guiding said slugs from the mold to the galley, and an automatic device' in the ath of the outgoing slugs to change the pat of the upper short slugs only.

4. In a line casting machine, the combination of molds for producing long and short slugs, means for delivering the-slugs from the molds, and guiding mechanism adapted to direct all long slugs in a common path and direct short slugs 1n dierent paths.

5. In a line casting machine, the combination of a mold, means for delivering slu s, means for guiding the delivered slugs,an a spring deflector, g, arranged to divert the outgoing slugs laterally from the path in which they left the mold.

6. -In a line casting machine, the combination of a divided mold adapted to form two slugs, an ejector adapted to deliver all slugs therefrom, a slug receiving galley, and guiding devices, located between the mold and the galley and ada ted to' deliver certain vof the slugs to the gal ey and others in a dilervpresence of two attesting witnesses.
