TYPGRAPHICAL MACHINE.

Leconte ters Patents to O. Mergenthaler, Nos. 436,531

and 436,532, wherein circulating matrices are released from a magazine or magazines in the order in which their characters are to appear in printand then assembled in line, the composed line transferred to the face of the slotted 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 there after elevated and returned through a distributing mechanism to the magazine or magazines from which they started. In such machines, the composed line of matrices is presented to the casting mechanism by a carrier, ordinarily known as the first elevator the presenting movement of which may be varied in order to bring the line into appropriate relation to the mold, and thus to permit the employment of different matrices or molds of diii'erent size as may be necessary. For instance, in the use of large matrices for head letters, it is customar to vpresent the elevator at a different level trom that at which it is presented with ordinary matrices, in order to insure the correct alinement of the characters thereon with the mold slot. Such machines are also provided with means whereby the trimming knives may be adjusted to slugs or linotypes of different thickness asA produced by different widths of the mold slot.

Itl is one of the purposes of my invention to effect the actuation of the means vfor arf resting the first elevator in a different position simultaneously with the adjustment` of the trimming knives, so that for any given thickness of slug, the proper position of the .elevator and the proper separation of the knives will be secured by a single operation. In this manner, I ohviate the necessity for special attention or care on the part of the operator, and also avoid the liability to imperfect results which arises in the event that specification of teneis raient.

the devices are not correspondingly adjusted.

In the accompanying drawing, I have shown my improvement by way ofexample and in preferred formand as applied to the specific kind of machine already mentioned, but obviously many changes'and variations maybe made therein, and similarly it may be used in connection with other forms of typographical casting machines, without departure from its spirit; and 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 such limita# tions are specified in the claims.

Referring to thedrawing: Figure 1 is a front perspective view olf' a portion of the casting mechanism of a linoty e machine, having my invention applied t ereto; and Fig. 2 is a transverse ,vertical section, showing'the parts in position fdr casting.

In most respects, the illustrated mecha nisms are or may be substantially the same as those disclosed in the previously mentioned Letters Patent, or as employed in the commercial linotype machine. The rotatable mold Wheel A is provided with one or more molds a, into which the molten metal is delivered from a melting pot (not shown). The matrices X are supported in the first elevator B and are thereby presented tothe mold. The extent of movement of the elevator is governed by the Contact with `the vise cap G of the stop screw I) carried by the elevator; and the rod E, ordinarily termed the automatic which controlsthe clutch mechanism, is actuated by the screw D1 also carried bythe elevator, the depression ofthe rod E being necessary t0 permit the castingioperation, when the elevator has reached its proper position. In ordinary circumstances, auch as in connection with matrices of ordinary font, wherein the characters are for example 14- point or less, the elevator B descends until the stop screw D contacts directly with the vise cap C, andthe screw D1 with the rod E. If it is desired to use larger matrices, `for instance for head letters, say, from ltpoint to E32-point or more, a stop member or piece F is employed which may be interposed at will between the screw D andthe cap C, which relations are shown'in Fig. 2. As previously stated, when the elevator' descends to its full extent, the screw D? actuates the clutch rod E; ybut when the eleson - ditional means were availed of. 'Io this end the stopv member F is provided with a pivoted finger or interponent F1, which will be inserted between the rod E and the screw D1, when the member F is brought into po-y sition to be engaged by the screw D, and thus effect the proper actuation of the clutch rod, even though the elevator be arrested at a higher point. Substantially similar devices are disclosed in Letters Patent to J. R. Rogers No. 890,177, except that therein the stop and pivoted interponent 'are adjusted by devices contacting with the keeper plate.

Referring to Fig. 1, I have illustrated the means whereby the knives may be adjusted to correspond to slugs of different thick'- ness. This is eifected by the movement of a handle H, connected to a rotary sector plate J provided with aseries of studs J 1 of different height, whereby the trimming blades may be properly adjusted. The handle H is formed with a pointer H1, which moves in relation to the point scale H2, thus permitting the setting of the knives to any size desired. Further detailed description of these adjusting means may be found in U. S. Letters Patent to I). S. Kennedy 1,002,281. Turning now to my improvement, it will .be seen that the sector plate J has on its edge adjustable studs K, located and arranged to contact with one end of the pivoted lever L, engaging a second pivoted lever M, which is in turn connected to the pivoted extension N of the stop member` F. The studs K are located in such position that they will engage and operate the lever L, when the handle H has been moved to adjust the trimming knives for ordinary slugs, in one case, and for Aslugs bearing much larger characters, in another case. Thus, in Fig. 1 the `handle H` is shown with its pointer H1 standing opposite point 36 on the scale H2, the movement of the handle to this position causing the corresponding stud K to operate the lever L, to bring the stop member F into its operative or arresting position. If now thehandle is moved in the opposite direction so as to locate its pointer opposite orbelow point 14 on the scale, the other stud K will'operate the lever L to withdraw the stop member F from its operative position, so as to permit the elevator to descend to its full extent. It will be obvious of course that the studs may be located in different positions on the sector plate J, so as to act upon the lever L for different adjustments of the trimming knives. i VV As previously stated, my invention may be carried into effect by other forms of devices,

which may vary widely from that shown in the present instance, both in construction and operation, and still be comprised within its scope. Such devices will readily suggest themselves to persons `skilled in the art.v

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 machine, the combination of a mold, a matrix carrier movableto diii'erent positions in relation thereto, knife adjusting mechanism, and connections therefrom to establish correspondence between the adjustment of the knives and the position ofthe carrier.

2. a typographical machine, the combination of a'mold, a matrix carrier movable to different positions in relation thereto, means for controlling the position of the carrier, knife adjusting mechanism, and connections between the said adjusting mechanism and the said controllingmean's.

3. In a typographical machine, the combination.of a mold, a matrix carrienmovable todiiferent positions in relation thereto, knife adjusting means, and devices actuated by said knife adjusting means for controlling the position of the carrier.

` 4.-. In a typographical machine, the combination of a movable matrix carrier, an adcarrier, and connections whereby the adjustment of said parts simultaneously effects the movement of Said stop device into or out of operative positionas required.

6. In a typographical casting machine comprising matrices, the combination of a lmold, means whereby the matrices and the mold may bebrought into different casting positions with relation to each other, knife 'adjusting mechanism, and connections between said meansand mechanism to establisi correspondence between the adjustment of the knives and the relation between the mold and matrices.

In testimony whereof I affix my signature in presence of two witnesses.
