JOHN RAPHAEL ROGERS, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTI-IALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Application filed July 19, 1911, Serial No. 639,340.

To all whom it may concern:

Be it known that 1, JOHN RAPHAEL Roo- ERS, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Typographical Machines, of which the following is a specification.

My invention relates to typographical ma-- chines, and more particularly to those of the class now known to the public under the vname linotype, as represented, for instance, in U. S. Letters Patent No. 436,532. in such machines the linotype or slug is formed in a mold connected to a rotatably mounted disk or wheel, whereby the mold is presented first in position to cooperate with a line of matrices in casting the slug, and is thereafter carried past a stationary knife to trim the base of the slug, and is finally arrested in front of an ejector blade by which it is forced from the mold. This disk or mold wheel is mounted on a supporting slide, whereby the mold is carried forward toward the line of matrices preparatory to the casting operation and is thereafter retracted to separate the edge of the slug from thematrices and to ermit the rotation of the mold wheel. Di culty has been experienced in the trimming of large or heavy slugs which ofier great resistance to the knife, because of the tendency of the wheel to spring forward away from the knife, which should remain in close contact with the rear face of the mold throughout the trimming action. This tendency if not corrected results in the slugs being left with either excessive or unequal height between their ends. To correct this difiiculty and to give more rigid support to the mold, machines have been constructed with a support or bearing arranged to act against the front face of the mold wheel and opposite the cutting edge of the knife on the rear side, whereby the wheel is supported in direct opposition to the knife, which therefore remains in close contact with the base of the mold from oneend to the other. Such an arrangement is shown, for instance, in the ll. S. Letters Patent to G. A. Bates, No. 722,354, March 10, 1903. One objection to the construction therein illustrated is that the rest or support F passes over and around the edge of the mold wheel and to the opposite face thereof, and therefore its loca-- tion is inconvenient and prevents the appli- Specification of Letters Patent.

cation to the mold wheel of various improvements and additions which have been devised in the more refined and rapidly growing art. In order to secure the same advantages and results, as previously set forth, and also to leave the front face of the mold free and clear from obstruction, I provide the mold support with clamping devices whlch engage a groove in the mold wheel, instead of passing around and beyond it as heretofore. In the particular form illustrated in the accompanying drawing, the clamping device comprises an extended finger so shaped and located as to engage such a groove in the edge or periphery of the wheel. However, other forms and variations will suggest themselves to those skilled in the art, and still be comprised within the scope of my invention; and, generally speaking, I desire it to be understood that the invention is not limited 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 perspective detail view of portions of the mold wheel and mold slide, and the clamping devices on the silde to engage the wheel; Fig. 2 is a rear elevation of portions of the mold wheel and mold slide, and also of the trimming knife and clamping devices; and Fig. 3 is a sectional detail taken substantially on the line 3-3 in Fig. 1.

Referring to the drawing, the mold wheel A is rotatably mounted on the mold slide B, and the knife E, which trims the base of the slugs or linotypes, is also connected to the slide B, all in the usual manner. The mold wheel A is, however, formed in its periphery with a groove C, between the ends of the teeth thereon and so as to leave teeth on opposite sides of the groove and on the slide B are mounted one or more clamping devices F, F, suitably shaped and positioned to engage in the groove. It will be seen that by this arrangement the wheel A. will be held in correct and rigid relation to the trimming knife E, and that the outer face of the mold wheel will be left clear and free and in such condition as to permit the application of other parts thereto.

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 linotype machine, the combination of a support, the toothed mold wheel rotatably mounted thereon the said teeth being cut away between their ends to provide a circumferential groove with teethv on 0pposite sides thereof, and fixed clamping means to engage in said groove and thus to hold the wheel in correct relation to its sup ort. 1 p 2 In a linotype machine, the combination of a mold slide and the toothed mold-wheel rotatably mountedthereon, the said teeth being cut away between their ends to provide a circumferential groove with teeth on opposite sides thereof, and the slide being'provided with means to bridge the teeth on one 15 side of the. groove and to engage in said hand this 18th day of July, 1911, in the pree 2o enoe of two attesting witnesses.'
