TYPOGRAPHICAL MACHINE.

1 Specification of Letters Patent. Patented J 26 1915 Application filed March 6, 1913. Serial N 0. 752,287.

To all whom it may concern vBe it known that I, EDGAR H. ATKINS, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Typographical Machines, of which the following is a spoolfication, reference "being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaler, wherein circulating matrices are released from a magazine or magazines 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 elevated and returned through a distributing mechanism to the magazine or magazines from which they started.

The present improvements relate more particularly to the font-distinguisher, which is employed to prevent matrices of different font from being delivered'into a magazine designed for matrices of a particular font.

7 Such mechanism is shown and described in an application for Letters Patent of David S. Kennedy, Serial No. 684,945, filed March 20, 1912, wherein the matrices of a given style or size have specially located font-indicating notches, and the font-distinguisher has a projecting finger similarly located, to permit the passage of corresponding matrices, and to arrest matrices formed with notches in a diiferent position, all as well known in the art.

i The said Kennedy application illustrates a style of machine employing a plurality of shiftable magazines, mechanism being also provided in connection therewith, whereby the distinguisher is automatically adjusted to correspond to the magazine in operative position. It sometimes happens that the size or style of a font of matrices in a particular magazine is changed, or that another magazine with different matrices is substituted therefor. The matrices of the-font thus substituted are of course formed with differently located notches, and I have therefore devised further'means'to adapt the distinguisher to these conditions also.

Obviously many changes and variations maybe made in the embodiment of the invention, and in its mode of application, without departure from its scope; 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 limitations are specified in the claims.

Referring to the drawings: Figure l is a perspective View of a portion of the distributing mechanism and the shiftable magazines, having my invention applied thereto; Fig. 2 1s a side view thereof, partly in section; and Fig. 3 is a sectional detail on the line 3--3 in Fig. 2.

The matrices X are transferred from the second elevator A into the distributor box C, wherein they are lifted one by one by the reciprocating finger A into operative relation to the customary distributing devices B, B, from which in turn they pass through the channel entrance D into their appropriate magazine channels. In the present instance, three magazines E E E are illustrated, any one of which maybe brought into operative relation to the other parts.

The font distinguisher F and its finger G are adjustably mounted in the box C, immediately in advance of the lifting finger A and in such position as to prevent the delivery of a matrix to the finger unless the notch therein corresponds in position to that of the finger G. The distmguisher F is provided with a spring H which normally presses it forward, the extent of this movement being regulated, by its contact with the pivoted lever arm J. The position of the arm J is in turn controlled by its contact with one or another of the plates K K K respectively mounted upon the magazines E E according. to the magazine in operative position. It will be observed that these plates vary in size, that is to say, that their forward or operative projecting portions are of greater or less extent, corresponding to the particular font carried by the magazine. Thus, in Fig. 2, the magazine E is shown in operation, and the plate K carried thereby, through the arm J, consequently holds the font distinguisher F and finger Gr in the osition indicated in full lines. The platell 3 of the magazine E is shown as projecting to a considerably greater extent than the plate K and consequently when the magazine E is brought into operation, the lever J and finger G will be moved inwardly to a greater extent, as indicated by dotted lines.

It will be understood that the adjusting plates are so proportioned as to register the finger G with the notches of the matrices contained in the corresponding magazines. The plates may be of any desired or appropriate form and connected to the magazines in any desired manner. In the drawings, I have shown them preferably as detachably secured thereto, by means of pins L on the side walls of the magazines and screws M passing through the plates and into the said side walls. In other words, the controlling devices are secured directly to the magazines, so that, not only does the shifting of a magazine into operative position properly locate the font distinguisher, but in addition, if a magazine be removed and another one substituted therefor, the controlling devices are simultaneously changed, without the necessity for the adjustment of the other parts and without requiring attention on the part of the operator, as'is necessary in the mechanism presented in the said Kennedy application. Further, the detachable connection of the plate to the magazine permits the ready substitution of one for another to correspond to a change of font in the same magazine. Obviously, such individual controlling means, to correspond to any particular font, could be employed with any interchangeable magazine, whether the latter be used singly or in connection with a plurality of magazines, as in the specific form illustrated; as in either event, the mere interchange of magazines effects the proper adjustment of the font distinguisher.

Many modifications and variations will suggest themselves to those skilled in the art and still be comprised within the spirit 'of my 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 machine, the com bination of a plurality of magazines, a latterally adjustable font distinguisher, and mechanism for automatically adjusting the font distinguisher laterally to correspond to the magazine in action, the said adjusting mechanism comprising controlling means carried directly by the respective magazines and corresponding to the style or font of the type or matrices therein.

2. In a typographical machine, the combination. of a plurality of magazines, a laterally adjustable font distinguisher, and variant means carried directly by the magazines to control the extent of lateral adjustment of the font distinguisher as one or another of the magazines is brought into action.

3. In a typographical machine, the combination of a plurality of magazines, a laterally adjustable font distinguisher, and a plate attached directly to each magazine to control the lateral adjustment of the font distinguisher, the said plates being of different form so as to vary the extent of the ad ustment.

4:. In a typographical machine, the combination of a magazine for the type or matrices, and an interchangeable font-distin guisher controlling device detachably secured thereto, the said device being of special form to correspond to the particular style or font of the type or matrices contained in, the magazine.

5. In a typographical machineythe combination of a shift frame, a plurality of magazines removably mounted therein, a

' font distinguisher, and mechanism for auto matically adjusting the font distinguisher to correspond With the magazine in operative position, the said mechanism including controlling devices carried directly by the respective magazines so as to be removable therewith and corresponding to the particular style or font of the type or matrices contained therein.

6. In a typographical machine, the combination of a shift frame, a plurality of the magazines into operation, a font distinguisher, and mechanism for automatically adjusting the font distinguisher to correspond with the magazi ".e brought into operation, the said mechanism including means whereby a substituted magazine will auto-' matically provide for the adjustment of the font distinguisher to correspond to the particular style or font of type or matrices therein.

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