TYPoGRArHIoAL MACHINE.

Original application filed May 22, 1916, Serial No. 99,059. Divided andthis application filed November 4,

- 1918. Serial no. 261,000;

D To all whom z'tmay 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- Machines, of which the following is a specification, reference being had thereln to the accompanying drawing, being a division of orlginal application filed May 22, 1916, Ser.

My invention relates to typographical machines such as linotype machines of the general organization represented in Let ters Patent of the United States to Ottmar Mergenthaler, 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 line transferred to the face of a mold, the mold filled with molten metal to 7 form a slug or linotype against the matrices which produce type charactersthereon,'and the matrices thereafter elevated and re-* turned through a distributing -mechanism to the magazines from which they started. More particularly, the invention relates to machines of this class in which provision is made for removing the magazines and replacing the same by another containing a different font of characters, and the invention is directed to certain improvements designed to facilitate the removal and replacement of the magazines, which improve- I ments will be pointed out in the detailed description to follow. y

In the accompanying drawings I have shown my invention embodied in a machine of the kind illustrated in my prior Letters Patent No. 1,104,512, but it is equally applicable to machines of other lands, or to typecasting and typesetting 9 machines, etc., which handle type or dies instead of matrices. In other words, I have shown my invention only in preferred form by way of example, and obviously many changes may be'made therein and in its mode'of application which will still be comprised within its spirit. 7 Generally speaking, I desire it to be understood that I do not limit myself to any-specific form or embodiment'exc'ept in so far as such limitations'are specified: in the claims.

Referring to the drawings Figure 1 is a side elevation of a portion of a linotype machine having my invention applied thereto;

Fig.2 is a similar view showing the parts in a different position- Egg. 3 1s a section on the line aa of Fig. 2;

Fig. 4 is a section on the line bb of Fig'. 3; and r Fig. 5 is a view similar to Fig. 4 showing the parts in different position.

In the accompanying drawings:

The matrices are stored according to font Patented May 2'7, 1919.

in the magazines A and B which in the I.

magazines substitutedtherefor containing" different-fonts of matrices; and the matrices are released from the which means of escapement mechanisms E arranged in two banks or series, one bank for each magazine. .Each' escapement mechanism consists as' usual of a rocking lever and a pair of pawls which are projected alternately by the lever into the correspondparticular magazine for the time being is in use, by

ing magazlnechannel to control the release of the matrices, the said rocking levers being operated from the keyboard of the machine by actuating reeds G and operat ing levers f v In therform of machineshown, the base frames A and B carrying the respective magazines may by the operation of a hand lever I be moved upwardly from the position shown in Fig. 1, and then separatedfrom each other as shown in Fig. Q-ino rder to facilitate the removal of the magazines, and as the mechanism for thus manipulating theseparts'is foreign to my present in- V vention-and is described and claimed in an original application filed'by me on the 22nd day of May, 1916, SenNo. 99,059, of which the present application is a division, a description ofsuch mechanism willbe unnecessary for an understanding of this invention.

My present invention is concerned with the method of mounting and supporting the escapement mechanisms 'on the respective base frames, and since both series of escapements are identical in construction and mounting, the present description will be confined to one series only, the one selected being applied to the upper base frame A. The escapements comprising the rocking levers and pawls above mentioned, are supported in series in a bar or frame K which is pivotally connected to the base frame as at K so as to allow the escapements to be swung into and out of operative relation to the magazine at will to permit the independent removal or replacement of the magazine. The escapements are held in operative relation to the magazine by a pair of spring actuating latches L which are pivotally connected to the upper ends of laterally swinging arms M pivoted below as at M to the side members of the escapement frame K. It is merely necessary therefore to disengage the latches from the magazines to permit the downward swinging of the escapements. It will be apparent, however, that when the escapements are moved out of operative relation to the magazines, the contained matrices would be free to pass therefrom unless they were first locked therein. Devices are therefore provided to prevent the disengagement of the latches L until the matrices have been locked in the magaine. In this instance (see particularly Figs. 3, at and 5) such devices comprise a plate N mounted to slide backwardly and forwardly in guideways in the upper face of the left side member of the escapement frame, the said plate being provided at its rear end with a locking stud or projection N adapted to engage in a recess or aperture in the forward face of the adjacent latch carrying arm M. The plate N is formed in its upper. side with an inclined slot N wherein engages the inclined stem portion 0 of a Z-shaped block O mounted to slide transversely to the right and left in corresponding guideways in the escapement frame. Due to this interconnection of the parts, the movement of the block 0 to. the right and left effects a corresponding movement of the plate N forwardly and backwardly respectively, causing the looking stud N to be engaged with or disengaged from the arm M. A spring 1? hearing at one end against a fixed portion of the escapement frame andv at its opposite end against an upstanding nose Q on the block 0 tends to constantly hold the latter to the right and consequently the plate N rearward with its locking stud N en.- gaged with the recess in. the swinging arm M. Disengagement of the locking stud is effected by the usual matrix locking bar R which is inserted through the edge of the magazine in the customary manner. This bar, as it is pushed home, engages the right I end of the sliding block 0' and shifts it to the left against the action of its spring, thereby withdrawing the locking stud from the recess in the arm M as shown in Fig. 5. hen the matrices are so locked in the magazine, the arms are free to be swung upwardly to disengage the latches L there from (see Fig. 3) and the escapement frame may be then swung downwardly to detach the escapements from the. magazine as shown by dotted lines in Fig. 2. The magazine may then be removed independently from the machine and when its substitute is put into. place, the escapements, are swung back into. operative relation thereto. and securely engaged therewith. The magazines being separated from each other as shown in Fig. 2, there is ample space between them to permit the downward swinging. of the escapements forthe upper magazine when, the latter is to be removed.

It will be understood that while. I have shown my invention in connection with a machine. employing. two. magazines movable with their base frames as described, and separable from each other, it will be understood that the invention is, not confined in its application to two magazines nor to.

magazines movable with their base frames, but is applicable as well to. machines employing a single magazine as will be apparent to. those. skilled: in the. art.

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.
