BALFOUR C. SNYDER, OF BROOKLYN, NEW YORK, ASSIGNO-R TO MERGENTHALEB- LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE Speciflcation of Letters Patent.

Patented Nov. 17, 191 4.

Application filed August 26, 1914. Serial No. 853,694.

To all whom it may concern:

Be it known that I, BALFOUR C. Snrnna, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented. certain new 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 and spacers thereafter returned through ,dis-

tributing 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 restored to their places of storage, and it is a principal purpose of my invention to prevent the too sudden and violent action .of some of these parts in certain circumstances, as will hereafter more fully appear from the detailed description thereof.

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

leferring to the drawings: Figure l is a side skeleton view, partly broken away, of a portion of a linotype machine, having my improvements applied thereto; Fig. 2 is a similar rear view Fig. 3 is a front View, on an enlarged scale and partly broken away. of the matrix and spacer transfer devices, etc: Fig. 4 is a somewhat similar view, showing the parts in different position; and Fig. 5 is a sectional detail of the yielding abutment. I i

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 elevator G rises to its uppermost position, the line of matrices X and spacers Yis transferred therefrom by the .slide S into the t pper transfer channel R, where the matrices engage with the second elevator bar A. The bar A is carried by the arm B pro vided with an arm C located in suitable position to be engaged and actuated by the cam D, whereby the bar is moved upwardly into registration with the distributer box E, to which the matrices are'shifted in the ordinary way. The spacer hook U .is op- .eratively 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 U. The slide S is held in its retracted or inoperative position by the pivoted pawl 'or detcntF. In, normal operation, the detent F-i's tripped to release the slide by the eontactstlitgrewith of an abutment connected to the second elevator,

in such manner that wheri the latter de- 'scends into operative relation to the channel R, the slide is permitted to operate. Tl'v parts so far described-are or may be of any usual or preferred construction,.and except as hereinafter specified constitute no part of my present Invention.

The means for actuating the slide S and hook U are somewhat similar to those pre-' sented in Letters Patent of the United States to O. Mergenthaler, No. 557,000, wherein the parts are designated by substantially the same reference characters. The slide S is operated by the intermedate link .9 connected to an upright arm .9 mounted upon a shaft (designated herein by the letter L), which shaft has a depending arm 3 arranged to bear against the side face of the cam wheel a". This shaft is also provided.

with a second depending arm connected by a link or turn buckle s with the arm 8', which carries the spacer hook U. The shaft, and consequently the arm 8 and the connectcd arln s, are operatively moved by v 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 3. The cam is so formed that when the spring- 8 lie 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 elevator oar A, as a sudden 5 0r jerky action would project them violently and spill them into the machine.

It sometimes happens in use that the elevator bar A is prevented from descending at the proper time, as for instance when due to the arrest of the distributer, the matrices accumulate and a jam occurs which holds the elevator bar in its upermost position. 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 by the detent l although the I cam s has continued to move and has passed out of contact with the arm 8, as indicated in Fig. 2. \Vhen now the second elevator is freed and permitted to descend, that is to say, if it be equipped with the customary form of abutment, 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 2 and frequently withdisastrous results.

This dilliculty subjects the operator to great inconvenience, and ent'i'rely because it has been dillicult in actual practice to control the slide simultaneously with the clearing and lowering of the second elevator.

To overcome these objections, I have provided means whereby the elevator fails to release the detcnt when the transfer device is not under the control of the cam, and 4G specifically l secure this result by substituting a yielding men'ihcr for the rigid abutment previous? mt sled upon the elevator arm. In the form illustrated (Fig. 5), this devi comprises the longitudinally movable pin or stud M, the spring M. tending to hold it in normal or advanced conditiomand elements such as the nuts M for regulating the tension of the spring.

In ordinary circumstances, as when the machine is operating in the regular way, the strength of the springis adequate to trip the detent F and thus unlock the transfor devices, which conditions are shown in V Fig. 4. llowever, if for any reason, such.

5 5 as the failure of the second elevator to des into pci "ve relation to the upper nslcr I'hanncl, the transfer mechanism without being unlock d, the the end of the detent I and cold against the pull of the being observed that the arm in contact with or controlled who u subsequently the s no by the second elevator descends and the pin M contacts with the detent, instead of tripping the latter and permitting the unrestrained action of the transfer devices, the spring M yields against the resistance afi'ordcd by the strong engagement of the slide S with the end of the detent, thereby obviating the objcctions previously noted, this yielding action of the detent being indicated in Fig. 3. In order now to restore the parts to normal working relation, the operator moves the slide S rearn-ardly to a sufi'icient extent to release the detent, which is then tripped by the compressed sprnig M, after which he eases the parts over gradually and gently.

As reviously stated, I have shown my invention only in preferred form, and by Way of example, and as applied to a linotype machine, but obviously many modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled in the art, witlmut departure S from its scope.

Having thus described my invention, vits construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows: 9o

1. In a typographical machine, the com bination of a transfer device, locking means therefor, an elevator to release said locking means, a. cam to control the movement of the transfer device, and means whereby the elevator will fail to release the locking means when the transfer device is not under the control of the cam. V

2. In a typographical machine, the combination of the spring-actuated transfer device, the locking means therefor the second elevator to release said locking means, the cam to control the movement of the transfer device, and means whereby the elevator will fail to release "the locking means when the transfer device is not under the control of the on ma 3, In a typographical machine, the combination of the line transfer device, the latch for looking it normally against action, the second elevator for moving the latch to unlocking position, and a yielding member through which the elevator effects the movement of the latch.

l. Ina typographical machine, the cornhination of the line transfer device S, the latch F for locking it normally against action, the second elevator A, and a yielding member M carried by the elevator to engage the latch.

In testimony whereof, I have iillixed my signature in presence'of two witnesscs.
