To all whom it may concern:

Be it known that I, THOMAS S. HOMANS, a citizen .of the United States, residing at Hempste'ad, in the county of Nassau and i State of New York, have invented newand useful Improvements in Linotype-Machines,

of Which the following is a specification.

This invention relates to improvements in linotype machines and more especially to the mold and means for mounting and adjusting the same, and it embodies a mold of improved construction and means whereby the same'may be adjusted readily for various changes in the sizeof body and length of slu .vIFh primary bjects of the invention are to enable the mold to be adjusted to a line of matrices, whereby letters or characters of 1 different font sizes located on the matrices to a common alinement basis or any special alinement will be suitably positioned on the mold, without varying the casting position of the matrices on the machine; to enable the mold to be adjusted downwardly with respect to a line of matrices, whereby slugs may be cast with heavy bodies and large type faces without aifecting the casting po sitions of the matrices on the machine and without causing a conflict between the matrix holder or elevator and the cap of the mold; and to provide improved means for mounting the mold, whereby the mold will be positioned accurately with respect to the mold. carrier and related parts of the machine and the various adjustments may be made readily and with facility.

To these and other ends, the invention consists in certain improvements, and combinations'and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particu: larly in the claims at the end of the specification.

In the accompanying drawings :-Figure 1 is a front view of a portion of a linotype mold disk or wheel provided with a mold and mold mounting constructed in accordance with the preferred embodiment of the invention; Fig. 2 represents a section on the line 22 of Fig. 1; Fig. 3 represents a section taken radially through the mold disk, the mold and the elevator which presents the matrices to the mold; Fig. 4 is a view similar to Fig. 1 showing a different adjustment of the mold and illustratinga slug cast view similar to Fig. 5 showing a matri keeper employing a single ledge; Fig. 9 is a. face View of a type slug such as thatshown in the mold in Fig. 4; Fig. 10 is a diagram illustrating the manner in which type faces of different font sizes have a common alinement.

Similar parts are designated by the same reference characters in the several views.

The preferred embodiment of the invention is shown in the accompanying drawin s and will be described hereinafter in detall, but it is to be understood that the invention is not limited to the particular construction shown and described, as the invention may be carried out effectually by constructions which differ specifically but are the equivalents of that shown. I In the present instance, 1 designates the mold carrier or support which is in the form of a disk or wheel as commonly employed on the well known linotype machines and having the peripheral gear teeth 2 whereby the mold is brought to the casting, trimming and ejecting positions. According to the present invention. each mold is mounted on pads or lugs which project from the face of the mold disk or carrier, a pair of pads or lugs 3 and 4 being shown in the present in stance and these pads or lugs serve to gage or accurately position the mold with respect to the mold disk or carrier and to secure the mold adjustably thereto. These pads or lugs have suitably finished opposed surfaces 5 and 6 which are adapted to cooperate with the ends of the mold body, thereby positioning the same in a longitudinal direction, and these pads or lugs also have suitably finished surfaces 7 and 8 which serve to accurately gage or position the mold with respect to the center of the mold disk or carrier.

The customary practice in the operation of the usual linotype machines is to adjust the mold cap only when changing the 'mold to cast lines of type or slugs of different body sizes. Such practice resulted in locat- 1 ing the matrix face of each different font size in a different position of alinement. For example, in Fig. 10 the lines ab and ccZ represent a large slug having the characters H and j thereon, and the lines e-f and gh represent a smaller slug bearing the same characters but of smaller font sizes. The line a-b represents the line of the body of the mold and the line 0-0? representsthe line of the cap of the mold relatively to the larger slug, and the line e f represents the line of the body of the mold and the line g-h the line of the cap of the mold with respect to the smaller slug. It is obvious that if the mold cap were lowered or brought nearer to the body of the mold in order to cast type of the smaller size face while the body of the mold remained stationary or fixed, the alinement line represented as Z-Z in the diagram would have to be lowered also in order to properly locate the type of small size, and hence the necessity heretofore of positioning the matrix faces bearing letters or characters'of different sizes, at different levels. Therefore, if the alinement line 1-1 is to remain constant for type faces of different font sizes, the mold body must be adjusted according to the adjustment of the mold cap, or the matrices must have varying casting positions on the machine. The present invention provides a mold the bodv and cap of which may be adjusted readily and type faces of different font sizes may all be cast on the slug in common alinement. In the present embodiment of the invention, the mold body 9 abuts against the positioning faces 5 and 6 of the pads or lugs 3 and 4 but is capable of adjustment in parallelism with these faces, the reduced portion 10 of the mold body bearing against a face of the mold disk and longitudinal extensions 11 and 12 project from the opposite ends of the mold body and beneath the pads or lugs 3 and 1-. Screws 13 and 14. extend through the pads or lugs 3 and 4 and the threaded portions thereof cooperate with the extensions 11 and 12 of the mold body, and turning of these screws in appropriate directions serves to adjust the mold body to vary the dimensions of the mold cavity to cast lines of type of different body sizes. The matrix keeper 15 which serves to properly position the line of matrices for the mold, according to the present invention,'occupies a fixed relation to the mold disk or support, this keeper in the present instance bearing against the outer face of the reduced portion 10 of the mold body and is secured in fixed relation to the mold disk by the screws 16. The matrices may be presented to the mold by the usual first elevator which is designated 17 in the present instance, the matrix keeper 15 having one or more ledges to cooperate with the ears on the matrices. In Figs. 1, 3, 4, 5 and 7, this matrix keeper is provided with two ledges 18 and 19 whereby two letter matrices may be positioned at two levels before the mold, while in Fig. 8, the matrix keeper 20 has a single ledge 21 to coiiperate with the ears of single letter matrices. By using an adjustable body mold and a relatively fixed matrix keeper, the matrices will occupy an invariable or constant position with respect to the casting mechanism of the machine.

The mold cap 22 may be of different constructions, that shown having extensions 23 and 24- which are adapted to project over the pads or lugs 3 and 4:, and the mold cap may be adjusted to conform with the adjustments of the mold in casting lines of type of different body sizes by liners which are interposed between the mold cap and the positioning surfaces 7 and 8 of the pads. The

present invention provides liners of improved construction which perform the dual function of spacing the distance between the mold cap and body, and positioning the mold cap with respect to the pads or lugs 3 and 4 on the mold disk. Each liner in the present embodiment of the invention comprises a section 25 which is adapted to rest upon the top gaging surface 7 and a section 26 which is adapted to project more or less into the mold cavity according to the length of the line of type to be cast. The thicknesses of these two sections 25 and 26 of each liner will vary according to the ad justments of the mold cap with respect to the mold disk and the distance between the mold cap and body, the upper surfaces of both sections being in alinement and in the same plane to fit closely against the outer surface of the mold cap, while the lower surfaces of the liner sections may he stepped or in different planes according to the different adjustments. Each liner may be pro vided with a transverse rib 27 to engage-in or lug to position the liner properly in a direction longitudinally of the mold, and

each liner may be slotted as at 29 to accommodate the screws 13 and 14: previously described and the screws 30 and 31, the liner being adapted for insertion and removal by a transverse movement, that is to say, a movement longitudinally of the transverse rib 2-7. The mold cap and the liners interposed between it and the pads or lugs 3 and 4c are secured to the mold disk by the clamp ing screws 30 and 31 which pass through the extensions 23 and 24 of the mold cap and are tapped into the pads or lugs 3 and 4, while as previously stated, the screws 13 and 14: serve to hold the mold body in differcnt positions of adjustment relatively to the mold disk. The sections 26 of the liners,

when the screws 13 and 14 are tightened, those sections of the liners will serve as gages to set the mold to cast lines of type of the selected body size.

Another feature of advantage obtained by the present invention is that a relatively wide range of adjustment is provided for the mold without interfering with the elevator which presents the matricesto the mold. Such elevators as used upon the well known linotype machine have an overhanging portion 32, and in following the usual practice of adjusting the mold cap only, the mold cap encountered the overhanging portion 32 of the elevator and thereby limited the adjustment of the mold to enlarge the cavity thereof. However, by adjusting the mold body as well as the mold cap, itis obvious that a considerably greater range of adjustment is afforded and slugs of a maximum body size may be cast without changing the operative position of the elevator which presents the matrices to the mold and without altering the relation of the matrices to the relatively fixed matrix keeper.
