specification of Letters Patent.

Application filed way 535, 1914;.

To all "whom it may, concern Be it known that 1, DAVID 8. Hanna 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 Machines, of which the following is a specification, 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. 436,53, to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to ap pear 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 distributing mechanism to the magazinc from which they started.

More particularly, it relates to such machines when equipped with a plurality of movable magazines, any one of which may be liifted into operative relation to the assembling deyices. As shown for instance in U. ti. Letters Patent to J. ltvliogers, No. 792,851, the several magazines are moved relatively to a single throat, through which the matrices pass from the selected one to the further assembling devices, and the throat is provided with a single series of escapement devices adapted to" control the release of the matrices from all the maga zines as they are successively brought into position. In machines of the kind illustrated, in the Rogers patent, and to prevent the mixing of fonts, means are provided whereby matrices remaining in the throat are restored to their proper magazine, bcfore it is shifted and another one takes its place. In order to obviate this necessity, I employ an arrangement of escapemcnt devices, the operation. of which insures the delivery of the matrix in the throat, leaves the throat empty, and also eli'ccts the retention of the lowermost matrix in the magazine, so as to leave the latter ready for free and unimpeded shifting. The particular means. for effecting this resuit will be described in the-specification and finally pointed outin the claims.

In the accompanying drawing, 1 have shown my invention in preferred form and by way of example, and as applied to the form of machine already referred to, but many changes and variations may be made therein, and in its mode of application, which will still be comprised within its spirit. Thus, the particular arrangement and construction of the parts may be varied, or its may be applied to other forms of typographical machines, such as typesetters, typecastcrs and the like, which handle type or dies, instead of matrices. Generally speaking, I desire it to be understood that I do not limit myself to any particular form or embodiment, except in' so far as such limitations are specified in the claims. l

Referring to the drawing: Figure 1 is a vertical section through the lower part of the magazines, etc, of a linotype machine, having my invention embodied therein; and Fig. 2 is a similar view showing the parts in dili'erent position.

, As is usual in machines of this style, the matrices X are stored in a. plurality of movable magazines A, the shifting of which brings the selected one into OPPHtlK'Q, relation to the assembling devices. During this nwvement the matrices are held 120 place by the rock shafts or looking devices B, which may then be manipulated to tree the matrices of. the selected magazine. The release of the matrices is controlled by escapemcnt devices connected to the stationary throat F through which the matrices pass ito the raceway K.

The parts so far described, and their mode of operation, except in so far as subsequently pointed out, are or may be of any preferred or necessary form, and in themselves constitute no part of my invention.

The individual escapements each comprise a pivoted lever C, an upper pawl D, and a lower pawl E, which pawls are alternately projected intothe throat F, in the manner well understood iii-the art. The illustrated means for effecting the rocking movement of the lever C comprise the spring G normally tendin g to move the upper pawl D into operative position, and the reed J and lover H, the action of which Withdraws the pawl D and projects the lower pawl E into the. throat. I t w'll be noted that the pawls D and E are so oc'ated that the upper one stands" normally beneath the lowermost 'ma-' trix mithe magazine and mcngagement with the edge of the matrix previously released that as the pawl D moves inwardly against the matrix, the latter is displaced edgewise.

As the pawl E is simultaneously retracted, the matrix passes from the throat and the latter is cleared.- The intermediate or abnormal position of the escapement is'shown matrix in the magazine. It will be seen that in Fig. 2,'wherein the upper pawl D is with drawn and the lowermost pawl E projected, which permits the descent of the lowermost matrix in the magazine and its arrest by the pawl Elf-The return movement restores the.

parts to the position shown inFig. 1,. allowing the released] matrix'to drop from the throat and insuring the retention of the next due to this arrangement of the parts, the magazine is always-free and readyto be shifted, and that the necessity no longer exists for restoring matrices to it from the throat F. If it be desired to move'it to inoperative position; all that is required is the locking of the matrices therein by the manipulation of the, rockshaft 13,

As previously stated, I have shown my invention only in preferred form and by way of exar'nple, and as adapted to a specific kind of machine. However, many modifications and alterations therein, and in its modeof adaptation, will suggest themselves-to those skilled inthe art, without departure from its scope.

Having thus describedmy invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is asfo'llows:

4 1. In a typographical maehi-ne,'t he combination of a'eolumnoftype or matrices, and an escapement to c'ontrolfltheir release, the

said escapement con'i'prising two pawls which are projected alternately into'the pathof movement of thetype or matr ces, and one of which pawls shifts the matrices ctlgcariso in effecting their release. 1 '2. In a typographical machine, the combination of :1 column of type (ii-matrices, and an escapemeut to control their release, the

said escapeinent comprising two pawls which are projected alternately into the path of movement of the type or matrices, the upper one. of said pawls standing normally in engagement with the lowermost matrix in the column and acting to shift it edgewise in its subsequent return to normal Position.

3. In a. typographical machine, the combination of a magazine to contain the type or lowermost matrix in the magazine and act ing to shift it edgewise in its subsequent returnto normal position.

4;. In a typographical machine, the com; binationof a magazine for the typeor mat therefrom, and an escapement comprisingtwo pawls acting in the throat tocontrol the passage ofthe type or matrices therethrough, the upper one of said pawls standing nor rices, an exterior throat to receive them mally in engagement with the lowermost matrix in the magazine and act1n: "te.sh ift it n'iatri'ces, and an escapement .rnounted ex ternally of the magazine to control their release therefromft-he said. cscapement com- 65 cdg'cwise in its subsequent return to normal I position.

5. In a typographical machine, the combination of a-magazine fort-he type or matrices," an exterior throat to receive them i therefrom, and an escapemcnt comprising.

two awls'acting in the throat to control the passage of the type or matricestherethr'ough, one'of said. payvlsadapted to shift themedgewise in their passage, and the semi throatbeing cut away at its. farther side to permit such edgewise shifting of the type or matrices. I

6. In a typographical machine, the combination of a stationary, throat, a plurality of magazines movably arranged to hring one or another thereof into operative relation to i e the -tl1roat,-' and an eseapement comprising two pawls acting in thethroat to control-the passa of the type or matrices tl'lerethrongh, 'the'upper one of said pawls standing normallyin engagement with the lowermost matrix .in the selected magazine, and the throat hing formed to permit said matrix to be shifted edgewis'e by the upper pawl in its subsequent return to normal position.

7 In a typographical machine, the some binationof a magazine for the type-or mt flees," and a reciprocating eseapement'monnted exteriorly of the magazine and compr1s-- mg t-wo pawls, the upper one of which.

stands normally in engagement with the lowermost. matrix in the'magazine, the noat v rices being shittahle edgewise by the upper pawl in its subsequent return to normal position;

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