LINOTYPE-MOLD.

specification of Letters Patent.

Patented Oct. 10, 1911.

To all whom 'it'may concern: 1

Be it known that I, DAVID PETRI-PAL- MEDQ, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Linotype-Molds, of. which the following is a full, clear, and exact description.

This invention relates to 'molds adapted for use in line casting machines in connection with an assembled line ofmatrices for casting linotype. 3

The object of the invention is to provide a mold in which may be produced hollow linotype or type bars, such as form the subject-matter of my application filed concurrently with the application for this patent.

The invention consists in the combination with a slotted mold, of a core or cores projecting into the mold slot from the rear thereof, the rear ends of said cores being in the same plane with the rear face of the mold.

It also consists in the construction and combinations of parts shown in the drawings and hereinafter described and defined by the claims.

In the drawings Figure 1 is a front view of a mold and its carrier or frame. Fig. 2 is a rear view of the same. Fig. 3 is a hori-v zontal section on line 33 of Figs. 1 and 2.

Fig. 4 is, a vertical section on line H of Figs. 1, 2 and 3 Fi 5 is a similar section showing the mol adjusted for a con siderably thinner slug than that which would be produced by the mold as shown in Figs. 1, 2, 3 and 4, and with a core to cor-' respond. Fig. 6 is a sectional view similar to Figs. 4: and 5 but showing the mold adjusted for a slug of a size intermediate between that produced by the mold sl1own,in Fig. 4 and that produced by the mold shown in Fig. 5, the core being the same, however, as the one shown in Fig. 5. Fig. 7 is a perspective View of three of the cores. Fig. 8

1s a perspective View of the product, a-

' hollow linotype.

. Referring to the parts by letters, A represents the moldv carrier, which is "in the form of a rectangular frame, in which is a rectangular recess for the reception of the mold proper.

The mold B is of conventional construction consisting of a top member If, a bottom member I), and the right and left hand leave the mold slot 6 between them. This mold is removably held in the carrier by the ters a recess in the mold carrier,the tail piece being secured to the mold carrier by screw 01 These cores are of slightly decreasing cross sectional area from their rear toward their front ends. Preferably several of these cores are employed. If they .are they should be set a short distance only apart, so that when a linotype is cast in the mold slot, said linotype will have the transverse vertical ribs 0 which extend from the front to the rear walls of the linotype as shown in Fig. 8. Among the reasons for preferring to fix the tail pieces of the core to the mold carrier instead of the mold, the following may be mentioned, viz. the same cores may be utilized without readjustment for several sizes of mold slots,especially in a machine, in which both the top and bottom of the mold slot occupy different positions relative to the carrier when a mold with a different width of slot is put into the carrier. If the substituted mold has a narrower slot the side walls of the linotype produced therein will be thinner. This will be understood by reference to Figs. 5 and 6, which show molds whose slots difler in width, whereas the cores are alike. Moreover the mold maybe removed and another tion of the cores to the carrier.

liners b b, which parts when assembled It is to be understood that in using the described mold the front side, 2'. e. the left side as shown in Figs. 4, 5 and 6, is to be closed by a line of matrices, while the rear side of said slotis to be closed by a nozzle which engages the rear faces of the mold members. Since the rear faces of the cores and their tail pieces are flush with and continuations of the rear faces of the mold members, such a nozzle as is ordinarily used may been: loyed in connectionwith the described mb d.

Having described my invention, I claim:

1; The combination of a slotted linotype mold having a recess in its rearface, with a core havingfla laterally extended tail piece which fits said recess and is rigidly fixed vtherein, the rear face of said tall. piece behaving recesses in their rear faces with a 15 core which projects into the mold slot from the rear and has a tail piece which. is fitted into the recesses in the mold and mold carrier and is secured to the latter, the rear face of said tail piece being flush with the rear 20 face of the mold.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
