T o all whom t may 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 Coinposing-Machines, of which the following is a specification, reference being had therein to the accompanying drawing, being a division of original application led May 22, 1916, ser. No. 99,059.

- My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States to O. Mergen-v thaler, No. 436,532, wherein circulating matrices under the action of escapements are released from a magazine in the order in which 'their chanacters 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 form a slug or linotypeagainst the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned througha distributin mechanism to the magazine from whic they started.v

The present invention is directed to ycertain improvements in the escapement operating devices, as will be more fully pointed out in the detailed description to follow.

In the accompanying drawing, for the sake of simplicity, I have shown my improvements in connection with a single magazine only, although it is my purpose to emlbody them in a machine equipped with a plurality of magazines which are movably arranged in such manner that any selected vone thereof may be brought into operative position at will, such for instance as illustrated in my pending application Serial No. 99,059, filed May 22, 1916, of which the present application is a division. It should be I understood, however, that the invention may ,be embodied in any class of machine to which it is applicable. In addition, I have shown my invention only in preferred form and by way of example, and obviously many changes and variations may be made therein and in its mode of application which will still be comprised within its spirit. Generally speaking, I desire it to be understood lthat I do not limit myself to any specific he drawing is an enlarged vertical sec`V tion taken through the escapement operat- -ing dev1ces and the magazine with which they coperate. v i

The matrices X are stored in the magazine A and pass therefrom into the assembler entrance C under the action of the escapements M mounted in fthe supporting frame M1. rIhe frame M1 is provided' with a series of sliding plungers; N1 by means of which the escapements are rocked in one directlon to release the matrices against the action of springs M2 which vtend constantly to rock them in the Opposite direction. These plungers are actuated by a series or bank of levers N pivoted as at N 2 to a fixed part of the machine' frame and operated by vertically movable4 reeds N5 reciprocated by powerdriven mechanism under the control of the keyboard, all in the usual way. Heretofore, andas shown in my prior Letters Patent N o. 1,104,512 the actuating levers for the escapement plungers have been made in substantially L-shape form and have had their pivots located well to the rear of the forward ends of the magazines. In this old arrangment, the parts were subjected to considerable wear asa consequence of the sliding or wiping engagement between the levers and the plungers, as well as between the levers and the operating reeds, occurring at each operation. It is the object of the present invention to avoid this objectionable wear, and to that end I have modified the form and arrangement of the parts in such manner as to reduce the' friction to a minimum.

As shown, the actuating levers N are of considerable length and practically straight throughout and have their pivotal points located in an inclined plane disposed substantially at right angles to the magazine, (and consequently at right angles to the escapement plungers N1) and passing through the point of engagement of the actuating levers with the escapement plungers. As a result of this arrangement, when the actuating levers are rocked about their pivots, (as shown by the dotted lines) their upper ends will describe an arc to which the longitudes of the escapement plungers are tangent, and the circular measure of such arc will be substantially equal to the sine of the angle of rotation; or more generally speaking, the upper ends of the actuating levers will move practically in a straight line which coincides with the longitudinal aXes of the escapement plungers, thereby avoiding any appreciable sliding or wiping engagement between these parts. The levers N are slightly voffset near their middle,

as at N3, to avoid interference` with the vertical mdvement of the magazine and are Y parts when operated.

As before stated, I have shown my improvements merely in their preferred formY and by way of example, and as applied to a particular kind of machine, but obviously many modifications and alterations therein and in their Inode of application will suggest themselves to those skilled in the art without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Pat'- ent of the United States is as follows:

l. In a 'typographical composing machine, the combination of a matrix-releasing escapement, and operating means therefor, the said means including a sliding plunger connected to the escapement, and va pivoted actuating lever of relatively great length and arranged with its upper end in position to engage said plunger and having its pivotal point located in a plane extending substantially at right angles to the plunger and passing through the pointof engagement of the lever with the plunger, said pivotal point being positioned a relatively remote distance from the escapement-plunger so that inthe pivotal motions of the lever, its upper end will describe an arc to which the longitude of the plunger is tangent, and the circular measure of which are will be substantially equal to the sine of the angle of rotation, whereby wear from sliding of thelever on the plunger is prevented. Y

2. Inv atypographical machine, the combination of a magazine, a series of escape'-- m ments therefor, and means for operating the escapements, the said means including sliding plungers connected to the escape` ments, actuating levers arranged with their' upper ends in position to engage the plungers, and devices to operate the actuating levers, the said devicesbei-ng shiftably mounted and interlocked at their upper ends with the actuatinglevers so asto-rock there- ,y n

with.

3. In a typographical machine', the combi'- nation of a magazine,a series of escapements therefor, and-meansfor operating the escapements, the said means comprising a series of operating devices and an interme# diate series of pivoted levers through which the movement of the operating devices is imparted to the escapements, the said del-1 vices being shiftablyarranged and interlocked at their upper ends with the` pivoted levers so as to rock therewith. Y

In testimony whereof, I signature hereto.
