Application filed July 27 0 ail whom it may concem:

Be it known that I, EDWIN W. PIERSON, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Typographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to typographical machines, such as linotype machines of the general organization represented in U. S. Letters Patent to O. Mergenthaler No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print, then assembled in line, the composed line transferred to the of a slotted 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 thereafter returned through distributing mechanism to the magazine from which they started. In these machines, the composed line is transferred from the assembling channel or elevator into the casting channel or elevator by means of a horizontally movable carriage comprising a slide or body portion and a pair of line engaging fingers, one short and the other long. The short right-hand finger is fixed to the carriage slide, while the long left-hand finger is loosely mounted with reference thereto, the latter finger being ordinarily provided with a friction device which tends" to hold it stationary. As the transfer carriage is thus constructed, the composed line is advanced to'the left by the righthand finger and in its advaneepicks up the left-hand finger. and carries it along therewit it being understood thatthe frictional resistance offered to the movement of the left-hand finger is overcome by the power applied to operate the carria e. In the return movement of. the carriage, the lefthand finger is restored to the right by the customary adjustable stop on the carriage slide which locates it-at theproper distance from the right-hand finger f lhe loose mounting of the left-hand finger is intended primarily to enable the transfer carriageto accommodate itself to short lines, that is to say, lines shorter than that; for which the two fingers are adJusted. Thus, when a short line dehveredto the transfer parria'ge,

the leading matrix of the line necessarily stands some distance away from the left hand finger, but this distance is immediately taken up during the initial movement of the transfer carriage, due to the fact that the left-hand finger is held at rest until picked up by the advancing line. In this way, the two fingers are caused to approach each other and confine the line between them, reliance being placed upon the above mentioned friction device to maintain the fingers in this condition until the line is taken from the carriage by the casting elevator- It has been found in practise that, notwithstandthe friction device carried thereby, the let hand finger frequently becomes separated from the line before the latter leaves the transfer carriage, such separation being due for the most part to the jar developed by the abrupt stoppage ofthe earriage in its delivery position. As a result, the matrices become loose in the line (particularly those at the leading end) and oftentimes drop out or else become so displaced as to interfere with the proper delivery of the line to the casting and other devices, thereby causing damage to the parts and giving rise to other serious objections,

The present invention 1s intended to over-' come the foregoing objections and aims to provlde an effective guard against the separation of the two line engaging fingers.

under the conditions stated. To this end, specifically, the left-hand finger is provided, in addition to its customary friction device, with a spring-actuated pawl or detent held i engagement with the usual ratchet teeth on the carriage slide and which acts to lock the left-hand finger against relative movement toward the left or away from' the right-handfinger while'permitting an initial independent movement of the latter finger in forwarding the line. (3n the return move nient of actuated pawl er detent is automatically disengaged by; a suitabletrip. device on the machinefframe so as to permit the lefthand finger to resume its original position.

Brieflystated, the arrangement is such that, during the transfer of the line, the two the transfer carriage, the spring LOO . fingers are allowed to approach each other between them and are n a 1n oonnningv the line v separation then. positively locked against until the line is taken away. T V

in the accompanying drawings, the inven the other fin tion has been shown merely in preferred form and by way oi example and as applied to the particular kind of machine mentioned, but obviously many changes and alterations may be made therein and in its mode of application and still be comprised within its spirit. Generally speaking, the invention is not limited to any specific form or adaptation except in so far as such limitations specified in the claims.

Referring to the drawings:

Fig. 1 is a front elevation of a portion of a linotype machine equipped with the prose; t improvement Fig. 2 is a similar view, on an enlarged scale, of the line transfer carriage and associated parts; I

Fig. 3 is a plan View thereof, and showing the left-hand linger of the transfer carriage in locked condition;

Fig. 4t is a similar view but showing said finger unlocked; and

Fig. 5 is a transverse section taken on line 5-5 of Fig. 2, looking toward the right.

In the drawings, only those parts of the machine necessary to an understanding oi? the invention have been illustrated, and it will be understood that the other parts may be of the ordinary or any suitable construction. 1

T he matrices X are released from the magazine A by the manipulation of the heyboard A1 and drop onto the conveyor belt A-2 which delivers them into the assembling elevator A3, wherein they are composed in line with the spacers Y. After composition, the elevator A-3 is raised into registration with the intermediate channel C and the composed line then carried therethrough into the casting elevator D, which thereupon descends to present the line to the casting and other devices (see the dotted line showing in Fig. 1). The slitting oi the composed line from the assembling: elevator h 3 to the casting" elevator D s etl'ected by means of a so-called transfer carriage comprising; the horizontal slide or bot portion l5 and the two line engaging: ii ere and l3-2.

ihe foregoing parts and their mode of operation 016 substantially as shown and described in he Rogers Patent No. '4 to which Once may be had it d However, may be noted that, wh" trans is moved to the l the tra e composed line, hand lin er if 2 1S hem rest by th V :2 0 m +1 r r m, l m, -i inter-i ble ioinaid cud ol the .Ult. armed against it by the advance or the rightdiand anger (compare l and l power apnhed to ance the air sutiic ent or course to overcome the :trictio al resistance of the plunger B 8, and conscrpiiently the '3-2 1: c ricd er .l by the con'ipe-sed ine lllltll the riage its delivery position, where it is aren 'ement oi slide 2 on the machine the line tea-mm id l distance between ement with ts i i 1t oi arrest ol 1 i carriage (life to the initial l .7 t movement of the slide l3), and hence the finger has tendency to jump or ebound away irom the line when the carriage is arrested. illercto'tore, the plun- T --8 has been relied upon to resist this tendency ot the inner, but in actual practise it is found that the jar developed by t ahrupt stoppage ot the carriage is are eneue h to overcome the frictional resilience oit'lhe plun 'cr, thereby giving rise to the o vionsly noted. fie-cording to the i are provided to?) pr it in ention, means positively locking; the left-hand against movement under the conditions, as will now be described in detail.

lln the preferred embodiment illust* ed. the means employed consists of a too ied pawl or detent E carried by the sliding bloelr B4 and normally held in e ment with the ratchet t eth on the by a springer? lib-4. ll seen at once that, by reason of this J and ratchet arrangement, the finger 3-2 positively locked against movement town i toe left relatively to the slide B, althor the relative movement of the parts in opposite 4. rect on is eiv permff' follows, therefore, that when the carriage 1s moved to the left in forwarding the composed line, the plunger B8 tunetions as before to hold the finger at rest until engaged by the advancing line Sti (the detent E yielding readily to permit such initial independent movement of the sli le B), but when the finger is picked up and carried along by the advancing line, such relative movement of the parts immediately ceases, and the detent E then acts to lock the finger in its new position to the carriage slide (Fig. 3). This condition obtains throughout the remainder of the t-ransfer movement of the carriage and in fact until the composed line is taken from the carriage by the casting elevator, so that any lateral displacement of the left-hand finger before the line is delivered to the casting and other devices is thus positively prevented.

When the transfer carriage is returned to the right for receiving the next line, it is important that the left-hand finger be restored to its original position so as to stand at the proper distance from the right-hand finger, it being obvious that a succeeding may be longer than the preceding one. For this reason, means are provided for automatically disengaging the detent E from the slide B during the return movement of the carriage. In the present instanc there is employed for the purpose a trip device F located on the machine frame above the guideway Ol and in the path of travel of the forwardly extending arm of the spring-actuated lever E--1. This trip device has a hinged section Fl' which, during the line-forwarding movement of the transfer carriage, will yield or move out of the way when engaged by the lever (see Figs. 2 and 3), but which, during the return movement of the carriage, will serve as rigid abutment to engage and operate the lever for the withdrawal of the locking detent (see Fig. 4:). When the pawl is thus withdrawn, the finger 13-2 is immediately brought to rest by the spring-pressed plunger B--8 and remains so until ngaged or picked up by the stop B6 (see dotted lines Fig. 4:), which then carries it back to its original position. i

As previously stated, the invention has been ShOWn only in preferred form and by way of example and as applied to the particular type of transfer carriage noted, but obviously many changes and alterations in the various parts and in their mode of ap: plication will readily suggest themselves to those skilled in the art without departing from the spirit of the invention.
