Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed. October 3, 1913. Serial No. 793,193.

T 0 all whom it may concern:

Be it known that I, GEORGE E. BENJAMIN, a citizen of the United States, residing at 'Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to machines in which printing slugs or bars are cast in a slotted mold and then delivered therefrom by an ejector blade which advances against the edge of the slug. In many of these machines the molds are variable or adjustable in length in order to produce slugs for print ing columns or pages of different widths; and in connection with such an adjustable mold is frequently employed a composite ejector having its parts so constructed and combined that its operative portion may be varied in width to correspond with changes in the length of the mold slot. As illustrated for instance in Letters Patent of the United States, No. 967,976, to John R. Rogers, the ejector blade is composed of a series of parallel sections arranged edge to edge, and a mechanism is provided whereby any desired number of these sections can be connected with the actuating slide, while the others are left free therefrom. In this construction also t 1e sections are firmly supported and guided on both sides to prevent their internal buckling or bending under the thrusting strains to which they are subjected in action. However, when the ejector projected into the mold, and thus its end is moved beyond this lateral support, there is a tendency to bend or distort the protruding portion and to disturb the alinement of the individual sections, this tendency varying with the amount of resistance offered by the slug.

It is the purpose of my invention to minimize this liability, and to that end 1 preferably construct the individual sections to interlock and thus support each other, without afiecting their capability of relative movement and individual adjustment.

In the accompanying drawing, I have illustrated my invention in preferred form and by way of example, and as applied to the style of machine already mentioned, but obviously, many changes and variations may be made therein, and in its mode of application, which will still be comprised within its spirit.

Generally speaking, I desire it to be un derstood, that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawing: Figure 1' is a side elevation, partly in section and broken away, of the mold and ejecting devices, with my invention applied thereto; Fig. 2 is a perspective view illustrating the interlocking connection of the ejector blades, etc; Fig. 3 is a transverse section through several blades; and Fig. 4 is a similar view of a modified form.

Referring to Fig. 1, the mold disk A is provided with the usual slotted mold B and is mounted upon the slide C, and the slide D is arranged to reciprocate horizontally on the slide C for the purpose of actuating the ejector. The ejector proper E comprises a series of parallel blades or sections 6, which sections are arranged one above another, and are guided between the vertical face of the mold slide C on one side and the vertical plate F on the opposite side. The several sections are free to move forward and backward independently, and also so that any desired number may be brought into action jointly, to form an ejector of a vertical width corresponding to the length of the slug which is being cast in the machine, while the other sections remain inactive in their inner or backward position. Each ejector section a is actuated by a correspond-- ing member G, which members are mounted i grooves 0 formed in the mold slide 0. In order that any required number of the sections 6 may be coupled to the actuating slide D, while the other sections remain free, I employ the vertically movable bar H, carried by the slide D, and having its lower end arranged to travel forward and backward on the rod I attached to the vertical slide J. The parts and operations so far described are or may be substantially the same as those disclosed in the said Rogers patent, wherein also the same letters of reference are employed.

The support afforded to the blades or sections 6 by the face of the'mold slide C and the vertical plate F is adequate to prevent the internal buckling or bending of the blades; but as the latter are commonly made very thin to enable them to engage thin slugs, and as these slugs frequently offer substantial resistance, it sometimes happens that when they are advanced, and their end portions thus freed from the said supporting means, these ends will be sprung or bent and thus forced out of alinement, resulting in injury to the mold, knives, or themselves. As previously stated, it is the purpose of my invention to obviate or minimize this difliculty, and this end I preferably accomplish by an interlocking engagement between adj acent blades, such as the tongue-and-groove connection M shown in Figs. 2 and 3. It will be seen that due to this arrangement the sections 6 are still relatively movable and may be longitudinally adjusted in the manner already set forth, but that due to the lateral resistance thus afforded by one to another, the liability to their individual buckling is materially reduced, and their proper alinement insured. Fig. a shows a slightly modified form of construction, wherein the tongueand-groovc connection N is inclined or beveled.

As previously stated, I have shown my invention only in preferred form and by way of example, and as applied to the specific kind of machine indicated. Obviously, many modifications and alterations therein, and in its mode of application, will suggest themselves to those skilled in the art, without departure from its scope.

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:

1. In a typographical machine, the combination of an ejector comprising a series of parallel blades or sections having on their adjacent edges the components of blade interlocking and bracing means forming an interengaging connection between each two blades of the series and actuatin means 7 21 therefor adapted to be connected to any desired number of the blades.

2. In a, typographical machine, the combination of a slotted mold, an ejector comprising a series of blades or sections movable into the slot'in the mold and having on their adjacent edges the components of blade interlocking and bracing means form ing an inter-engaging connection between each two blades of the series, and actuating means therefor adapted to be connected to any desired number of the blades.

3. In a typographical machine, the combination of a slotted mold, a slug-ejector comprising a series of independently movable blades actuatable into the slot in the mold and'having on adjacent edges the components of blade bracing and interengaging means for preventing bending. and buckling of the portions of the blades projected into themold slot, and actuating means for projecting any desired number of the blades into said slot.

4-. In a typographical machine, the coming and inter-engaging means for prevent ing the bendingand bucklingof the portions of the blades projected beyond the end of the slide, and actuating means for projecting any desired number of the blades.

5. An ejector for typographical machines comprising a series of slidable members, each two thereof having at adjacent edges the components of blade interlocking and bracing means.

In testimony whereof I have ailixed my signature in presence of two witnesses.
