TYPOGRAPHICAL CASTING-MACHINE.

Specification of Letters Patent.

Patented June 17, 1919.

Divided and this application filed March 19,

1919. Serial No. 5288,5211}.

To all whom it may concern:

Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical Casting-Machines, of which the following is a specification, reference being had therein to the accompanying drawing, being a division of original application'filed August 16, 1916, Serial No. 115,151.

My invention relates to typographical machines, such as linotype machines, of-the general organization represented in Letters Patent of the United States to O. Morgenthaler, No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line,

the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned ,through a distributing mechanism to the magazine from which they started.

My present invention is directed to improvements in the casting devices of such machines and is intended to adapt these devices for producing slugs with characters of greatly increased size or point, such as is frequently desired in connection with headlines, advertising or display work, etc. Heretofore, this class of work has been taken care of by the old hand setting method, as prior automatic machines have been incapable of producing slugs with characters little or no greater than a half inch in height or about 12 pt. cap. In accordance with my invention, I am able to cast directly in the machine in the usual way slugs with characters far greater in height or about 60 pt. cap., a result which I believe I am the first to achieve. 'The manner in which this result is obtained will be fully pointed out in the detailed description to follow.

In the accompanying drawings, I have shown my improvements in preferred form and by way of example and as applied to a machine of the kind above noted. It will be obvious, however, that my in'lprovements may be embodiedin other forms and applied to machines ,of' other constructions with-out'departing from the spirit of my invention. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as suchlimitations are specified in the claims.

Referring to the drawings Figure l is a vertical section of the casting devices;

Fig. 2 is a proved mold;

Fig. 3 is a detached perspective of one of the new matrices; and

Figs. 4 and 5 are comparative views showing the difference between the old and new forms of mold and matrices, respectively.

The drawings have been confined to those parts of the machine immediately concerned with the'present invention, and the other parts may be of any well known or 1; proved construction. However, for a ma chine capable of handling matrices such as I propose to employ, reference may be had to my pending application, Serial No. 115,151, filed Aug. 16, 1916, of which the present application is a division.

1 shows the relation of the parts perspective view of the imdurmg casting, the mold Dbeing closed at the front by the assembled line of matrices X in the first elevator C and at the rear by the mouthpiece D of a melting pot, the matrices being formed in their front or mold engaging edges with characters or cavities X (see Fig. 3) to produce the type characters on the slug cast in the mold. mold is supported on the rotary disk D which after casting carries the mold around to a vertical position between a pair of trimming knives at the front and an ejector blade at the rear, the latter being slidably arranged to push the cast slug from the mold between the knives which act upon the opposite side faces of the slug to trim it to the exact thickness required.

The mold illustrated (Fig. 2) is of the recessed or head-lettcr variety, comprising the body portion D the cap portion D and the intermediate liners D and D, the

The c grooves D and the intermediate ribs or filling pieces D. These parts are held together by the studs D projecting up from the body portion and engaging in notches in the opposite ends of the cap portion, the liners being held in place by tongue and groove connections with the'body portion. \Vhen the parts are thus assembled, they produce a slug comprising a relatively thin body portion, an overhanging face portion orshelf upon which the type characters are formed, and a series of transverse ribs projecting from the body portion and giving support to the overhanging shelf. How ever, if desired-the mold may be plain so as to produce solid or unrecessed slugs.

As is well known when the matrices are presented to the mold their lower projecting ears X onv the contiguous edges engage beneath an alining rib D on the body portion 1) of the mold (see Fig. 1); and while so engaged, the matrices are shifted upwardly by a, slight rising movement of the first elevator C to insure the proper alinement of the matrix characters with each other and with the mold slot, all in the usual way. The under face of the rib 1) thus constitutes the alining surface of the mold, while the upper faces of the cooperating project-ing ears X constitute the alining surfaces of the respective matrices. These alining surfaces bear definite relations to certain datum lines governing the manufacture and adjustment of the parts. Thus, the datum line of the mold, more commonly known as the constant line, is one usually passing through or coincident with the upper face of the body portion 1), when, as it customarily is, secured in fixed position on the disk D and the datum line of the matrices is one which passes therethrough at a point situated vertically above their alining surfaces a distance equal to thatbetween the alining surface of the mold and its constant line, this relation existing so that the two datum lines will coincide when the matrices are presented in proper casting relation to the mold. When so presented, the tops of the matrix characters stand in horizontal alinement with the upper face of the mold body portion D it being the common practice to aline the characters at their tops due to their inverted position on the matrix bodies. Heretofore in making use of different sized characters, they have always been extended above this normal datum line or so as never, irrespective of size, to extend below said line. Under this old practice ithas been possible to make use of matrices with characters of half an inch in height or about 42 pt. cap., but this has proved to be the extreme size, as there is an upper point beyond which the characters cannot be extended on the matrix bodies.

I have found that the size or vertical ex- .new form of mold.

resents tent of the matrix characters may in creased as much as one-elghth of an inch, which will allow them to be of 60 pt. cap.

or therealbout, without radically altering the construction of the existing parts and without changing the constant line of the mold. This result I achieve by recessing or reducing the thickness of the alining rib D so as to bring the matrix alining surface (constituted by its under face) nearer to the constant line of the mold or nearer to the upper face of the body portion D and by lowering the datum line of the matrices to a corresponding extent, thus allowing the matrix characters to be punched or extended below the normal datum line and consequently to approachnearer to their alining surfaces, whose location on the matrices remains unchanged. In making use of such the mold in an elevated position so as to shift them vertically with respect thereto to bring their abnormal datum line up to the level of the normal constant line of the mold, or, more generally speaking, to raise the matrix characters so as to aline them at their tops with the upper face of the mold body portion. This raising of the matrices is effected by arresting the elevator at the desired level by means of the adjustable set screw C carried thereby and which is adapted to engage the fixed vise frame Y as the elevator descends to present the line before the mold. In this connection, it may be noted that the set screw C which operates the vise automatic C is also adjusted to correspond.

The difference between the old and new forms of mold and matrices is clearly illustrated in Figs. i and 5, respectively, the old forms being located to the left'and the new forms to the right in these figures. Referring to Fig. 4, the line aa indicates the normal datum or constant line of the mold which is shown aspassing through the upper face of the mold body portion D The line ?)?2 indicates the alining surface of the old form of mold, and the line (2-0 the alining surface of the new form. The distance cl between the lines 5 6 and c-c is approximately one-eighth of an inch in the machine construction, and determines the reduced distance between the matrix alining surface and the upper face of the body portion D or the constant line of the In Fig. 5, the datum line of the old form of matrix is indicated by the line ww, and the datum line of the new form by the line y-' z The distance d between these two lines indicates the extent to which the matrix character X may be carried below the normal datum line and nearer to the alining ear X whose alining surface remains the same as heretofore, being indicated by the line z2. This disity.

naoaeoe tance d is equal to the distance d between the lines c0 and bb, indicating the re duction in thickness of the alining rib D on the new mold, so that by arresting the first elevator C at a correspondingly higher level, the abnormal datum line yy of the matrices is caused to coincide with the normal datum line a a of the mold when the matrices are presented thereto, and thus insure the proper alinement of the matrix characters at their tops with the upper face of the'mold body portion D as required.

The highest point to which the characters X may be carried up on the matrix bodies is indicated by the line ww in Fig. 5. Consequently," the maximum size or height of the matrix character available under the old practice is determined by the distance between the lines w-w and mw in that figure. It will be seen, therefore, that by modifying the parts in the manner above described I have been able to increase the size of the matrix characters very materially (the limits now being fixed by the lines ww and y3 and this without altering the standard dimensions of the matrix bodies and withoutv changing the constant line of the mold, such as would require a reorganization of the other casting devices. In this way the regular linotype machine is adapted for use in connection with work which had previously been beyond its capac- It will be understood that when the parts are thus designed to permit the use of the large matrices contemplated, the mold slot or cavity isincreased in width to cast slugs with characters of corresponding size. This increased width of slot is provided for by making the intermediate liners D and D of suitable thickness to locate the cap portion D at the proper distance from the fixed body portion D In the use of the old form of matrices, the greatest height to which the cap portion D could be adjusted is indicated by the line e-e in Fig. 4, but under the new practice the cap portion may be adjusted to the greater height indicated or to an extent equal to the-distance al which determines the increased size of the matrix characters.

As previously stated, I have shown my improvements merely in preferred form and by way of example and as applied to the particular kind of machine noted, b ut obviously many modifications and variations therein and in their mode of application will suggest themselves to those skilled in the art without departure from the scope of the invention.

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 casting machine,

ing of reduced thickness the combination of a slotted mold comprising a body portion formed with an alining rib,

and matrices having characters of increased ing formed with an alining rib whose under face provides an alining surface for the matrices, and the said rib being of reduced thickness to locate the matrix alining surface at a correspondingly reduced distance from the upper face tion, for the purpose described.

3. In a typographical casting machine, the combination with matrices formed with alining surfaces and having characters situated with reference to a datum line which is located at an abnormal distance from the alining surfaces, of a slotted mold havinga given datum line and formed with an alining rib which presents an alining surface adapted to be engaged by the alining surfaces of the matrices, the said alining rib being of reduced thickness to locate its alining surface at a distance from the datum line of the mold equal to that between the datum line of the matrices and their alining surfaces.

4. In' a typographical casting machine, the combination of a slotted mold having a normally located datum line, and matrices to codperate therewith and having characters situated thereon with reference to an abnormally located datum line, the said mold and matrices being provided with cooperating alining surfaces located at. equal distances from their respective datum lines.

5. In a typographical casting machine, the combination of a slotted mold formed with an alining rib of reduced thickness, matrices having characters of correspondingly increased height and formed with alining ears to engage said rib, and means for presenting the matrices in operative relation to the mold. 7

6. In a typographical casting machine, the combination of a slotted mold having a normally located datum line and formed with a n alining rib, matrices formed with ears adapted to engage said alining rib and having characters SltlliltGCl thereon with reference to an abnormally located datum line, and means for presenting the matrices to the mold in position to allow their datum lines to COiIlCldG, thealining rib of the mold being of reduced thickness to permit such presentation of the matrices with characters of correspondingly increased height.

7. In a typographical casting machine, the

of the mold body porcombination of a slotted mold having a nor mally located datum line and formed With an alining rib, and matrices formed with ears adapted to engage said alining rib and having characters situated thereon With reference to an abnormally located datum line, the said alining rib being of reduced thickness, so that in effecting the alinement of the matrices their abnormally located datum line will be caused to coincide With the nor- 10 mal datum line of the mold.

In testimony whereof, I have afiixed my signature hereto.

DAVID S. KENNEDY.
