Y., assignor to Interty'pe Corporation, Brooklyn, N. Y., a corporation of New York Application May 20, 1933, Serial No. 672,055 In Germany June 1, 1932 11 Claims.

The present invention relates to improvements in line casting machines of the well known class employing a pair of vise jaws for presenting lines of character bearing matrices to a mold for i casting type bars or slugs therefrom, an example of a machine of that class being disclosed in U. S. Letters Patent No. 436,532 granted September 16, 1890 to O. Mergenthaler.

It has been proposed to provide one of the vise jaws of such machines, on the side of such jaw next to the mold, with a mark such as an aperture or cavity which, during casting, will produce a corresponding projection on the cast slug, which will serve as a mark or guide to indi- 15 cate the point at which the slug is to be sawed ofi to the desired length, examples of such an arrangement and of the slug produced thereby being disclosed in U. S. Letters Patents Nos. 1,434,308 and 1,438,131 granted Oct. 31, 1922 and.

Dec. 5, 1922 respectively to A. H. Narrow.

It is sometimes desirable, however, especially when both vise jaws are moved toward one another for the purpose of casting slugs without type characters or of centering the type characters with respect to the length of the slugs and to avoid subsequent objections, such for example as objectionable printing from such projections which will stand at least as high as the type characters on the slugs or the necessity of removing such projections to render the slugs suitable for use, to omit the casting of such projections on the slugs, the omission of such projections from such slugs being possible since such slugs may be cast to the entire length and would 35.then be suitable for use without requiring any sawing off.

To enable this result to be accomplished, the present invention provides means whereby the aperture or mark carried by the vise jaw may be rendered inoperative in any desired manner such as automatically by the movement of the vise jaws toward one another or manually.

In carrying out the invention, it is preferable to employ an aperture to serve as the mark, and

when the aperture is to be rendered inoperative automatically, it is preferable to provide such aperture in the vise jaw and to provide apin for closing it automatically by movement of the pin under the action of a spring when the respective vise jaw is removed from its usual stop,

and when the aperture is to be rendered inoperative manually, it is preferable to provide the aperture in off-center position in a circular body which is rotatably mounted in the mold engaging face of the respective vise jaw so that the aperture may be moved out of the plane of the mold cavity by rotating such body.

In the accompanying drawing: Fig. 1 is a top plan, partly in section, of a vise jaw provided with means for automatically closmg and opening a marking aperture therein, the jaw being shown in its normal position against its stop and the aperture open;

Fig. 2 is a top plan of a portion of the vise jaw shown in Fig. 1 but showing the marking aperture closed; I Fig. 3 is an elevation of the vise jaw shown in Figs. 1 and 2, indicating the position of. the marking aperture with respect to the mold cavity;

Fig. 4 is a top plan, showing the invention applied to the vise of a typographical machine;

Fig. 5 is an elevation of a portion of a vise jaw provided with manual means for rendering the marking aperture operative or inoperative; and I5 Fig. 6 is a top plan of the vise structure shown in Fig. 5.

According to the embodiment of the invention shown in Figs. 1 to 4 inclusive, the rear or casting face of the Visa jaw a which is preferably the left hand or adjustable jaw in the machine, has an aperture 0 therein at the height of the slug casting cavity a: of the mold. A pin 71. fits slidably in said aperture and closes it when the vise jaw a is moved inwardly or toward the left from the position shown in Fig. 1. This pin it is located in a recess s in the matrix engaging face of the vise jaw a and is normally held in the retracted position shown in Fig. 1 by a spring 1, the aperture 0 being then open so that the slugs will be 9o cast with a projection corresponding to the aperture c. In order to push the pin it into the aperture c, a pin it is rotatably mounted in the vise jaw a, said pin having a cam head or toe I thereon which permits the pin it to recede in the aper- 5 ture 0, under the action of its spring 2, into the position shown in Fig. 1 when said cam head or toe l occupies the position shown in that figure, and when said cam head or toe l is in the position shown in Fig. 2, it will push the pin it into the 100. aperture 0 to such extent that its end lies in the plane of the mold engaging face ofv the vise jaw, as shown in the latter figure. The pin it has an actuating lever y fixed thereto and linked to a two-armed lever m one end of which is forked to receive a pin it on the lever a. The lever m is "pivoted at 11 on the guide oof the vise jaw a and is under the control of a spring p the act-ionof which tends to move said lever into the position shown in Fig. 2. A bar q is' freely movable end- 1-1 wise in the guide 0, it being held against the lever m by the jaw stop 1 on the machine when the vise jaw 11 is against its said stop, so that the pin h will then be retracted to open the aperture 0, as shown in Fig. l, but if the vise jaw a is movedinwardly or toward the left in Fig. 1, away from the stop 1, which occurs, for example, when casting slugs without type characters or slugs with the type characters centered thereon, the bar q will release the lever m so that it will assume the position shown in Fig. 2 under the action of the spring p, and the aperture 0 will then be closed by the pin h.

Fig. 4 shows the vise of a line casting machine having the present invention applied thereto, the vise jaw a cooperating with a companion vise jaw a and both jaws being movable toward and from one another and adapted to receive and clamp a matrix line between them and hold the matrixline in casting position in front of a mold X having the slug casting cavity at therein, the vise jaws having suitable means for moving them simultaneously and equidistantly toward one another to center matrix lines with respect to the used length of the slugs, such for example as racks u and 12 connected to the respective jaws and meshing with an interposed pinion w revolubly mounted on the vise frame. With such an arrangement, it will be understood that while the vise jaw 01, is in its retracted position against its stop 7, the latter, pressing against the bar q, will rock the lever 1n and cam head I into the positions shown in Fig. 1 and thus allow the spring 1 to hold the pin it in its retracted posi tion in the aperture 0, thereby opening the latter so that a projection will be caston the type character bearing edge of the type slug cast in the mold by metal which will enter said aperture from the mold cavity which will then be in communication with said aperture, but when the vise 'jaw a moves inwardly or toward the other jaw, as when centering a matrix line as shown in Fig. 4, the bar q will be carried away from the jaw stop r and the spring 10 will then act to overcome the action of the spring and rock the lever m and cam head Z into the positions shown in Figs. 2 and 4, thereby moving the pin 71. into the aper ture sufficiently far to completely fill or close it, so that no projection will then be cast on the character bearing edge ofthe slug. .Return of the vise jaw a against its stop T will cause the latter to press against the bar q and said bar will act on the spring tensioned end of the lever m to rock it into the position shown in Fig. l, the cam headZ then occupying a position which will allow the spring 1' to retract the pin it and thereby open the aperture 0, as shown in this figure.

Figs. 5 and 6 show manually controlled means for the same purpose, according to which a circular body b is positioned rotatably in a circular .recess in the left hand vise jaw a, the face of this body lying in the same plane with the casting or mold engaging face of the vise jaw a. The body I) is provided with an aperture 0 at a .point removed from its axis of rotation, and this aperture, as shown by the full lines in Fig. 5,

is at the height of the mold cavity a: so that a Fig. -5, said aperture being then located below the mold cavity and hence out of communication therewith, so that a slug cast in the mold while the aperture 0' is so positioned Will be without such projection, the body I) then presenting a smooth surface to the mold cavity at the casting level. The vice jaw a is preferably provided with a recess to receive a vertically movable plunger e having a handle d at its upper end, the plunger being connected atits lower end to said rotatable body by a pin 1 which extends across a recess g in said body and accommodates the lower end of the plunger, the latter being depressed as shown by the full lines in Fig. 5,to rotate the body I) in a direction tobring the aperture 0 into operative position as shown by the full lines in this figure, and raised into the dotted line position to rotate the body I) in a direction to carry said aperture into inoperative position as shown by the dotted lines in said figure.
