SPECIFICATION forming part of Letters Patent No. 722,354, dated March 10, 1903.

Application filed January 12, 1903. $erial No. 138,681. (No model.)

To (0% whom, it may concern:

Be it known that I, GEORGE A. BATES, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

In the Mergenthaler linotype-machine of the present day the mold in which the linotype or slug is cast is fixed within a vertical intermittingly-revolving disk, whereby the mold is presented first in a horizontal position to cooperate with a line of matrices in casting a slug and thereafter carried past a stationary knife to trim the base of the contained slug, and finally arrested in avertical position in front of an ejector-blade by which the slug or linotype isdriven out of the mold. This Vertical disk is mounted on a horizontal supporting-slide, whereby the disk and mold are carried forward toward the line of matrices preparatory to the casting operation and thereafter drawn backward to separate the edge of the linotype from the matrices and permit the rotation of the disk. Heretofore difficulty has been experienced in the trimming of large slugs offering great resistance to the knife, because of the tendency of the mold and disk to spring forward away from the knife, which should remain in close contact with the rear face of the mold throughout the trimming action. The springing of the mold forward, commonly at an inclination, results in the slugs being left of excessive height or of unequal height between their two ends.

The object of the present invention is to give more rigid support to the disk and mold; and to this end it consists, essentially, in a rigid support or hearing arranged to act against the face of the mold-disk adjacent to the mold, directly opposite the cutting edge of the knife on the rear side, whereby the disk and mold are supported in direct opposition to the knife, which consequently remains in close contact with the base of the mold from one end to the other.

Figure 1 is a front View of the mold-disk and adjacent parts. Fig. 2 is a top plan View of the same with one side shown in horizontal section through the mold. Fig. 3 is a side elevation looking in the direction of the arrow in Figs. 1 and 2, with a portion of the disk broken away to show the action of the knife.

Referring to the drawings, A represents the vertical intermittingly-rotating disk centrally supported by a journal revolving in an arm projecting laterally from the slide B, which is mounted to move forward and backward in the main frame of the machine.

0 represents the slotted mold secured in the disk, having an opening through it from front to rear of the dimensions of the required slug or linotype. The rear face of the mold is smooth and stands flush, or practically so, with the rear face of the disk. In this mold the slug or linotype D is cast, its forward edge bearing the type characters, and its rear edge, which is broken away from the mouth of the melting-pot, being raised and protruding slightly beyond the rear face of the mold.

E represents the trimming-knife, secured rigidly to the arm which supports the molddisk by means of adj ustingscrews. This knife has an upward inclination toward the front, and its cuttingedge is arranged in such position as to act closely against the rear face of the mold O as the latter is carried past it by the rotation of the disk.

F represents the rest or support forming the subject of the present invention. It is attached rigidly to the arm of the slide B in the rear of the disk and extended forward past the edge of the disk and returned on the front of the same, being extended upward against the smooth face directly opposite or in line with the cutting edge of the knife, or, in other words, so that a radial line extended from the center of the disk will pass through the edge of the knife on one side of the disk and through the arm or rest F on the opposite side. This arm is made to stand in close contact with the disk and to hold the same against any springing or twisting action as the knife acts against the rear edge of the slug in the passing mold in the manner shown in Fig. 3.

It will be understood that as the knife acts on the rear edge of the slug there is a tendency of the latter to move forward away from the cutting edge, the result being to spring the mold and the disk forward, so that the knife fails to trim the base of the slug exactly flush with the rear face of the mold. This tendency is resisted by the arm or rest F. It will be observed that the face of this arm extends both above and below the cutting edge of the knife, so that the disk supported on both sides of the point of resistance is practically Without tendency to tip or spring out of position.

Having described my invention, What I claim is-- 1. In a linotype-machine, the rotary moldcarrying disk, the disk-supporting slide, the slug-trimming knife mounted on the slide in position to act against the rear face of the mold, and the arm or support F secured rigidly to the slide and acting against the face of the disk directly opposite to the trimmingknife.

2. In a linotype-machi'ne, the rotary moldcarrying disk A, the trimming-knife E, fixed in position behind the disk to act on the rear face of the passing mold and the slug therein, and the rigid arm F seated against the face of the disk and extending upward to or above the level of the cutting-point of the knife.

3. In a linotype-machine, the slide B, the rotary disk A mounted thereon, and the mold C fixed in said disk, in combination with a knife E mounted on a slide in the rear of the disk, and an arm F fixed to the slide and extended past the edge of the disk and arranged to bear against the face of the same in line with the cutting edge of the knife and the center of the disk, whereby the tendency of the disk to tilt or spring during the trimming action is prevented.

In testimony whereof I hereunto set my hand, this 2d day of January, 1903, in the presence of two attesting Witnesses.

GEORGE A. BATES.
