TYPOGRAPHICAL. Macr-rrnnf 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 by escapements from a magazine or magazines in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the ma:- trices which produce the type characters thereon, and the matrices thereafter returned thru a distributing mechanism to the magazine or magazines from which they started.

In these machines, the magazines are usually mounted in such manner that they may be quickly removed and rep-laced by other magazines containing difl'erent matrix fonts. Before removing a magazine, however, it is customary to lock the matrices therein; in fact, this is necessary when the escapements are separated from the magazine, as otherwise the matrices would be free to escape therefrom. Hence, the commercial machines are equipped with devices which prevent the removal of the desired magazine until the matrices have been first locked therein. In some instances, as when the magazine is lifted out of engagement with the escapements, the locking devices are arranged to prevent the premature raising of the magazine; while, in other instances, as when the escapements are lowered out of operative relation to'the magazine, the locking devices are arranged to prevent the movement of the escapements as distinguished from that of the magazine. In either case, the lockingdevices referred to are controlled and actuated by matrix locking means, which in locking the matrices in the magazine releaseit for removal. There are two kinds of matrix locking means now in use, one being in the form of a detachable bar which is inserted and removed endwise thru the edge of the magazine at the right, and the other being in the form of a permanently at tached bar mounted on the magazine so as to be movable instantly to active or inactive position.

While the detachable bar is cheap to manufacture and presents other advantages over bars of the permanent type, serious difficultieshave arisen in its use in certain commercial machines, particularly those equipped with auxiliary magazines. In the latter class of machines, the proximity and arrangement of the auxiliary magazines and their associated parts inrelation to the main magazines is such that they interfere with the regular manipulation of the locking bars, and it is frequently necessary, in multiple magazine machines, to first raise. either the main-magazines or the auxiliary magazines as a whole from their last adjusted position in order to 1 insert or withdraw the locking bar and thereafter restore the magazines to their original position. As a result of this condition, which isgenerally inconvenient and troublesome, the interchange of magazinesrequires more time than it otherwise would. p

The present invention is intended to obviate these and other difi'iculties and contemplates a detachable locking bar which will presentevery' advantage of the old locking bar but which maybe eflectively employed and freely manipulated in locking and releasing the matrices of the main'magazines on'all machines, including those provided with auxiliary magazines. To this end, the parts are so constructed and arranged that the locking bar may be inserted and removed thru the edge of the magazine adjacent the magazine-'locking device, which is located at the left instead of'the right side of the magazine or the side opposite the auxiliary magazines, the bar being formed with an angular ofl'set portion which is adapted to engage and-actuate said device as the bar is moved to and from its active position.

In the accompanying drawings, the invention has been shown merely in preferred form and byway of example, but obviously many alterations and variations may be made therein and in its mode of application which will still be comprised within its spirit. It is therefore to be understood that theinvention is'not limited to any specific form or embodiment except in so far as such limitations are specified in the claims. v

Referring to the drawings: V Fig. 1 perspective view of a magazine and parts associated therewith showing the application of the present invention; and

Fig. 2 is a side elevation, partly in section,

showing the magazine in operative relation to the escapements and assembler throat.

The matrices X, see Fig. 2, are stored'in the channeled. magazine A from which they pass into the assembler throat or raceway B, under control of the escapementsG, the latter beingactuated thru the series of pivoted leversC from the regular keyboard mechanism, not shown. The magazine A is'or may be of. standard construction, thruout, comprising the upper and lower grooved plates A A and right and left hand side bars A A which latter sustain the plates in parallel spaced relation. At the front, the plates A A are extended by means of the usual heavier plate sections A A, respectively, which are also fastened to the side bars A A-*, the upper section A being formed with the inner longitudinal groove A arranged toregister withthe regulartransverse Openings A in the magazine side bars, and the lower section A being recessed or aperturede on its under side to receive the grooved portions of the escapement supporting bar C Asshown in Fig. 2, the escapement bar C is fixed tot-he magazine base frame D, while the magazine is adapted to be lifted out of engagement therewith preparatory to its removal. Consequently, the safety locking device herein illustrated is associated with the magazine rather than with the escapements and is intended to prevent the lifting ofthe magazine from its base frame until the mat- 'rices'have first been locked therein, This device is arranged as usual at the left side of the magazine adjacent the side bar A and consists of a latch or lever E disposed in the longitudinal plane of the magazine and pivotally mounted in a suitable bracket E fastened to the baseframeD. A light compression spring E seated in the bracket E and engagingthe latchE, serves to maintain'the latter resiliently in active position with its rear end directly opposedto a finger F risplate F' normally disposed in the plane of the base'frame Din position to directly engage alongitudinal bar A fast to the magazine ribs A Vith this arrangement, by turning the rock shaft F, the cam plate will be swung upwardly and downwardly and,

thru its engagement with the bar A", will raiseandlower the magazinerelatively to the base frame and the escapement bar C The rock shaft F is operated manually as usual by means of a pair ofside arm's F which are detachably mounted on the opposite ends thereof, and may belocked thereto in-any suit able manner in order to obtainv the purchase required; These arms are adapted tobank upon lateral; projections D of the base frame D when swung forwardlyto raise the magazine-and, at such time, serve not only to support the magazine during its removal but also'tofacilitate its replacement. The foregoingparts and their mode of operation are similar to those incorporated in the most recent linotype models and in themselves constitute no part of the present invention. For further information, reference may be hadto the McNamara. Patent'No. 1,586,316, dated May 25, 19:26.

The present invention is directed specifically to a novel schemefor locking the matrices in the magazinein such manner as to avoid the difliculties pointed out in the openin g statement. In the preferred embodiment illustrated", there is employed a detachable bar Gr which can be inserted into the magaproved bar Gin cross section is similar to the regular detachable bar heretofore used and hence will: fit within the opening A in the magazine side bar A and be properly guided in the longitudinal groove A of the plate section A? as it is thrust thru or withdrawn fromthe magazine. At one end, the bar Gris formed with an offset noseportion G which is arranged to engage the latch E and rock it out of'the path of the finger F as the bar is shoved home, it being noted (see Fig. 1)' that the bracket E is recessed or cutaway at E toiexpose aportion of the latch and permit its engagement by the nose G Preferably, the upper'corner of the latch portion exposed by the recess E is beveled off as at E for the purpose presently to appear. A lug or stop shoulder G formed on the bar G near the offset portion thereof, is adapted to engage the side of the magazine when the rod is shoved inwardly and serves to locate the rod endwise in its active position.

The operation of the parts according to the foregoing arrangement will now be clear. When it is desired toremove the magazine A, the rod G is first inserted therein thru the opening A inthe side barA and pushed toward the right until the stop shoulder G banksagainst the end of the top plate section- A to which it is opposed; The matrices arethuslocked in themagazine against escape, and the nose portion G will have-engaged the latch E and moved the rear end thereof out of the pathof the upstanding fingerF The magazine is'now free tobe lifted safely out of engagement with the es capements C to the removing position indicated. by the dotted lines in Fig. 2, this operation' being accomplished in the manner before described by means of theside arms F and the cam plate F As the magazine'is raised, the nose portion G is disengaged fromthe latch E and thelatter is allowed to resume its normal lock-ing position-under action of the spring E When the magazine is lowered, howeventhe nose G reengages the beveled corner E ofthe latch and by such engagement cams the latter out of the way so that the magazine may properly seat upon the escapement bar C After the magazine comes to rest on the base frame I), the side arms F may be removed from the shaft F, if desired, and the rod G withdrawn from the magazine, the latch E thru the later operation being released and again restored to its active position by the compression spring E Having thus described my invention, its construction and mode of operation, what I claim is as follows:
