chines, 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 in the order in which their characters are to appear in print and then assembled in line together with spacers 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 andspacers thereafter elevated and returned through distributing mechanism to the magazines from which they started.

More particularly, it relates to the means whereby, after the slug is cast, the matrices and spacers are returned to their places of storage. 7

.t is the purpose of my invention to simplify and facilitate the manual control of certain of these parts, as will hereafter more fully appear from the detailed description thereof. w

In the accompanying drawings, I have shown my invention in preferred form and by way of example, and as applied to a linotype machine, but many changes and variationsmay 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 that I do not limit myself to any specific form or embodiment, except in so faras such: limitations are specified in the claims.

Referring to the drawings: Figure l is a rear skeleton view, partly broken away and in section, of a portion of a linotype machine, having my improvements applied thereto; and F ig.2 is a similar side view.

As illustrated in the Mergenthaler patent previously referred to, or as is customary in the somewhat modified commercial linotype machine, after the slug is cast, and the first Specification of Letters Patent. P tented A g, 11', 1914; Application filed m 12, 1913. Serial no. traces.

elevator (not shown) rises to its uppermost position, the line of matrices and spacers is transferred, therefrom by the slide S into the upper transfer channel It (shown in dotted linesin Fig. 1)., and the matrices thus engaged with the second elevator bar' A. The bar A is carried by the arm B provided with an arm .0 located in suitable position to: be engaged and. actuated by the cam D,

wherebythe bar A is moved upwardly into registration with the distributor box IE, to which :the matrices are shifted in the ordinary way; The spacer hoolrU is operatively connected to the slide S, in such manner that when, the slide; moves the line into the transfer channel, the hook advances and engages the spacers remaining therein, and by its return movement restores them to the spacer magazine, The slide S is held in its retracted or. inoperative position by the pivoted pawl or detent F. In normal operation, the detent F is tripped to release the slide bythe contact therewith of the abutment A connected to the second elevator, in such manner that when the latter descends into operative relation to the channel R, the slide-is permitted to operate.

The parts so far described are or may be of anyusual or preferred construction, and in themselves constitute no part of my present invention.

The means for actuating the slide S and hook Uare substantially similar to those presented Letters Patent of the United States to O. h Iergenthaler, No. 557,000, wherein the parts are designated by the same reference characters The slide S is operated-by the intermediate link 3 connected to an upright arm s mounted upon a shaft (designated herein by the letter L), which shaft hasa depending arm 8 arranged to bear against the side face of the cam wheel 8 This shaft is also provided with a second depending arm connected by a link or turn-buckle a with the, arm 8, which carries the spacer hook U. The shaft, and consequently the arm a and the connected arm 8, are operatively moved by the powerful spring 8 connected to an arm 9 fixed on the shaft. The return movements of the shaft and arms are effected by the action of the cam s on the arm a. The cam is so formed that when the spring 8 acts to shift the slide S inwardly, its movement is controlled and uniform, as is necessary to secure the proper transfer of the matrices to the "eleva the. proper time, as for instancewhen due to the arrest of the 'distributer, the matrices accumulate and a jam occurs which holds the elevator bar A in its uppermost posi-' tion. When this happens, it is necessary for the, operator to leave his place at the keyboard and pass to the rear of the machine, in order to correct the difliculty and clear the parts. At this time, the slide ,S'is held. in its outward or inoperative position against the force of the spring 8 byjthe detent F, although the cam s has continued to move and'has passed out of its restraining contact with the arm 8. If now the second elevator is freed and permitted to descend, it trips the detent :F and releases the slide S, which shoots forward with great rapidity, because it is no longer under the control of the cam, and projects the line in front of it with excessive violence and frequently with disastrous results', This difficulty subjects the operator to great inconvenience, and entirely because it is 'impossible'to control the slide at the'rear of the machine simultaneously with the clearing and lowering ofthe second elevator.

To overcome "the objection, I have pr'ovided means whereby the actuating devices may be conveniently governed from the rear of the machine and at the same time that the second elevator is being manipulated. Pref-f erably I accomplish this result by mounting an arm or handle M on the rear of the shaft L, in proximity to the arm B of the second elevator, and so arranged that when the operator lowers the second elevator into. relation to the channel R, and at any time be-- starting of the automatic mechanism in the,

mannerwell understoodin the art.

As previously stated, I have shownv my invention only in preferred form and by way f-example, and as applied to a linotype ma- Gopies of this patent may be obtained for five cents' each, by addressing Washington, D. 0.
