'TYPGGRAPHICAI: MACHINE.

To all whom it may concern:

Beit known that I, JOHN RAPHAEL Rooms, a citizen of the United States, and a resident of Brooklyn, county of l iings, and State of New York, have invented a new and useful Improvement, in Typographical Machines, of which the following is a specification.

My invention relates to typographical machines, and more particularly to that class thereof known to the public under the name linotype, and of the general organization illustrated and described in Letters Patent of the United States to G. Mergenthaler, N0. assess.

In the respects herein illustrated and described the invention refers to the distributing mechanism, and more specifically to that portion thereof whereby the matrices are in dividually separated from a line and delivered to the distributing screws and rail. Somewhat similar devices are illustrated in my previous Letters Patent No. 942,845, and in the Letters Patent to Converse, No. 942,848, in both of Which'are shown 'andde scribed means for delivering the thinnermatrices to the distributor at short intervals and thicker matrices thereto at longer in- In the distributing: mechanism above referred to, the toothed matrices are lifted successively to, and suspended by their teeth from, a grooved distributor bar along which they are carried by the threads of adjacent screws, the arrangement being such that each matrix disengages from the bar at the proper point and falls between the screwsinto its appropriate. channel in the magazine. As the machines were commonly constructed, a matrix was lifted into engagement with the feed screws at each revolution thereof, or in. other Words, there Was-a 1173- t-rix between each turn of the screw-threads and the next. in consequence of this arrangement, the distance between thick matrices traveling along the distributer bar small, and it sometimes happened Was very that the lower end of an advancing matrix overt-00k and bound against the side of the preceding one, which had fallen from the distributor bar but had not had sullicient time to clear the advancing second matrix.

The result of such a Contact between the matrices was an interference with the proper distribution, as Well as possible injury tothe matrices, or to other machine parts.

Patented Apr. 1,1913. Serial No. 652,239.

The object of the invention is to overcome this trouble, by providing hetween each matrix and the one followingit on the distributor bar, a space suilicient to insure the descent of the first matrix so to'avoid contact with the next, substantiallyin the same manner as is set forth in the [letters Patent to myself and to Converse previously meiitioned. I therefore combiner-title the. ordinary devices for'sustaining" the matrix line, and for lifting the matrices successively from the end of the line to the screws of the distributor, means. controlled by the thick ness of the inatriccs,-in sucha Way that thin matrices will be delivered by each. action of theli'iting devices to the feed screws, so that each turn of the threads will the" eceive a matrix, while on the otherhahd, t thicker matrices will be liftedlby every second action of the lifting devices, so that they are received only between alternate turns of thescrew-thread.: In this manner the thin matrices are fed. along the distribuler bar at short intervals, While the thicker matrices are carried at longer intervals.

In many respects my devices similar to those illustrated for the same purpose in the beforementioned Converse patent, wherein the lifting finger E (see Figures 1,. 2 and 3) is formed with a retaining hookc adapted to engage at intervals with the stationary plate 6 It will be noted, however, that the hook and plate in this construction are located in immediate proximity to that portion of the E whereby the matrices are individually engaged. This a1 rangein'ent of the retaining means, and

their propinquity to the operative end of the finger, occasion considerable disadvantages and inconvenience, and are undesirable for various reasons, and it is therefore one of the principal objects of my inventioii to provide means for effecting substantially the same results, butwhich are located at a point remote from that at which the matrices'are engaged. I

Another principal feature of my invention is the provision; of the lifting fingetfor device with means which engage the indi w- -vidual matrices fiatopposite sides thereof during the liftingectionf "Means to engage the matrix atits front side are'alreacly in ice use, but there is sometimes a tendency' forthe inatrix to disengage itself in the opposite direction, and therefore apply means adapted to engage the matrix at the rear side also, the matrix being thus held at both sides during its upward movement.

The invention is susceptible of enibodiment in various modified or alternati e forms, only one of which is illustrated in the accompanying drawings; and, generally speaking, I do not desire to limit myself to any particular form or embodin'ient thereof, except in so'far as suchv limitations are spec-r lied in the claims.

Referring to the drawings: Fig. l is. a side view of the distributor lift box, having my invention applied thereto, partly in sec tion and partly broken away to showthe operative parts more clearly; Figs. 2 and 3 are substantially similar views, 'sho ring the parts in different positions; Fig. l is a trans: verse vertical section through the lift box; Fig. 5 is a detached detail view of the lifting and deflecting plate on an enlarged scale; and Fig. 6 is a vertical trans vers section showing the engagement of the matrix and finger.

Referring to the drawings, the distributing mechanism is provided as usual with the lon tudinally grooved distributor bar ii A and the rotating conveying screws 13. he line of toothed matrices X is delivered endwise and horizontally to the lift ing means, this being effected by the shifter or transfer device ll, which normally acts in the direction of the arrow in Figs. 2 and 3 to press the matrices against the stationary shoulders or ahutments K, K.

The lifting device comprises the pivoted frame or lever C and the lifting finger D pivoted thereto at E. The lever C is reciprocated about its pivot by the cam 'or eccentric B mounted upon the end of one of the screws B andlocated in position to engage the yielding rod- B connected to the lever C and held in en a ement with the cam or eccentric B by the spring B", all in the usual manner. The reciprocating finger D is shouldered at its upper end to bear beneath and against the front side of the foremost matrix X, in such manner that it lifts the matrix clear of the detaining shoulders K, K, and into engagement with the feed screws 13, by which it is moved horizontally onto the distributor bar A, the shoulders K, K, being inclined upwardly to assist in sustaining the matrix during such operation.

So far as described, the parts are or may be constructed and arranged in the ordinary manner, and if no further provisions were made, the finger D would at each upward movement deliver a matrix, regardless of its thickness, between the feed screws, and in such manner that therewould be a matrix between each turn of the threads and the next one. However, in order to presentthc thicker matrices only to alternate turns of t e screw-threads, I provide the following at ditional features: At the lower end of the finger D, and beyond its pivot E, I form the finger with the lip F; and to the frame,

or other stationary part of the machine, I secure a stationary blade or plate H. A spring G is mounted in the frame C and bears upon the finger D, so as normally to press the finger inwardly, and to cause 1t to engage beneath the foremost matrix, (see Fig. 1). As each matrix is lifted clear of the abutments K, K, it by the line following behind it under the influence of the transfer device J, and in so doing it moves the finger D to the position shown in Fig. 2, against the force of the spring G. If the matrix lifted be a thick one, the ringer will be turned so far that when it descends, and before it disengages from the matrix, the lip F will engage the inner side of the blade H, thus holding the finger in an inclined position, and so that it cannot engage beneath the next matrix in the line, I 5 shown in Fig. 3. It thus follows that he next upward stroke of the finger will bean idle one and that it will fail to lift a matrix. During this second upward movement, however, the lip F will he lifted clear of the plate H, and the finger will spring back against the second matrix form ng thefront end of the line, and on completing its descent will engage there under (see Fig. 1), so that at the third elevation the finger it will again lift a matrix to the feed screws. As the screws have in the meantime made two rotations, it follows that the second matrix will be received between the third and distributer bar at a substantial distance from the preceding matrix. The foregoing operations will be repeated Whenever the thicker matrices are presented to the lifting finger. When thin matrices are presented thereto, that is to say,'matrices of a thickness insufficient to carry the lip F be yond the plate H, the finger will elevate a matrix at each and every stroke. Thus, it will be seen, the matrices are presented to the distributer bar at longer or shorter intervals, according to their thickness, the thickness of the matrices acting directly to control the frequency with which they are delivered, or, in other words, the intervals between them on the distributor bar. As previously indicated, this operation and in the said Converse patent, but by reason of my improved arrangement the means for momentarily rendering device inoperative are located at a point remote from that at which the matrices are engaged thereby, thus. correcting any disadvantage or inconvenience that otherwise mightarise.

is pushed forwardfourth turns of the screws, and consequently delivered to the.

the results thereof are similar to those set forth the matrix lifting"
