TYPOGRAPHICAL MACHINE Filed June 26, 1930 2 Sheets-Sheet 2 IN VEN TOR Patented May 31,. 1932 UNITED STATES PATENT OFFICE RICHARD SE. IMEAD, OF QUEEN-S VILLAGE, NEVJ" YORK, ASSIGNOR LINOTYPE COMPANY, A CORIEOBATION OF NEW YORK I TYPOGRAPHICAL .MACHINEE Application filed June 26,

This invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United "States No. 436,582 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, 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 thereafter elevated and returned 7 through distributing mechanism to the magazine from which they started. More particu l arly, it'relates to machines equipped with a plurality of magazines containing different matrix fonts and which are arranged to be moved upwardly and downwardly in'the ma chine to bring one or another into operative relation to the assembling and distributing mechanisms. 7 A a In these machines, the magazines 'are mounted in such manner that they may be quickly removed and replacedby other magazines containing different matrix fonts, it being customaryto apply to the base frame of the magazine to be removed a pair of supporting arms on which the magazine may slide forwardly when disengaged from its base frame. f

It sometimes happens that'the magazines are prematurely disengaged from their base frames, or improperly, placed thereon, so that they slide off when the supporting arms are not in position to receive them; and in that case, the falling magazines are likely to cause considerable damage to themselves or to other. portions of the machine, as well as injury to the operator. The present invention is therefore directed to certain improvementsin machines of the class stated intended to lock the magazines inplace and to prevent their release except when the supporting arms are in position to receive them, The construction and arrangement of thef'parts will best be, understood from the detailed description which follows. p l

. WVhile as above stated, the invention is in-- tended for use more particularly in machines 1930. Serial No. 463,836.

equipped with a plurality ofshiftablemagazines, it is also applicable to machines of the single magazine variety. Referringto the drawings: I Figure 1 is aside elevation of a portion of a linotype machine equipped with the invention; v V Fig. 2' is a similar view on a larger scale, showing the front portions of the magazines with their base frames and associated parts, and indicating how the magazines are re moved; 3

Fig. 3 is a longitudinal sectional view on line 33 of Fig. 2; an'd R L Fig. 4i is a fragmentary top plan View of the new automatic look at one side ofthe magazine. i

The matrices are stored according to font in the superposed channeledmagazines A,

three of which are shown herein but of which a greater or'less number might be employed if desired. The several magazines are re movably supported upon separate base frames A conjointly constituting a shift frame which is arranged to be moved'upwardly and downwardly in the fixed machine frame in the well known manner to bring any selected magazine into operative relation to the assembling mechanism B at the lowerend and the distributing mechanism (3* at the upper end; Each of the magazines is provided with a series of matrix releas ing escapements D '(Fig. 2) which, when the magazine is brought-into operative position,', I

are actuated under the controlof the key board mechanism in the usual way.

In the present instance, the two upper base frames A are pivotedat their upper ends, as I at A toa pair of plates rising from the lowermost baseframe, so that the base frames and their. respective magazines may be separated or spread apart to permit the inde-' pendentremoval of any selected magazine.

Southern, Serial No. 399,956,. filed October 7 16,1929,t0 which reference maybe had for do tails if desired. When in use, the magazines 55 1 of and fast toa transverse rock shaft F our frame to disengage it from the escapement bank preparatory to its removal or replacement, such lifting means being preferably constructed to support the magazine in its elevated position and to guide it in a straight path as it is drawn forwardly from the front of the machine. I

As best shown in Fig. 2, each bankof escapements D is mounted in the usual manner in a supporting bar of frame D which frame is screwed or otherwise fastened to the lower end of the corresponding-baseframe A As ordinarily, the magazines are formed on their undersides 'withtransverse slots or openings to receive the escapement bars, the latter being formed 'on their upper sides with grooves which extend across the magazine openings and constitute in effect continuations of the grooves in the bottom plates of the magazines. Such being the relation of the parts, it is apparent that before a magazine canjbe removed, it must first be disengaged from its escapement bank. V

For this reason, each base frame is provided with a central magazine lifting and supporting plate E, which in the present instance is substantially as long as thebase frame itself and which located in a corresponding groove or recess E formed in the upper side of the base frame; VAt its upper end, the plate E ispivoted to the base framein the usual way, thus permitting it to be swung upwardly in lifting the magazine; and at its lower end, it is provided with stop shoulders E normally engaged with the customary forward transverse rib a on the underside of the magazine andwhich thus retain the magazine in place on the plate when the latter is in its raised position. v

' The swinging of'the magazine lifting and supporting plate ofeach base frame is controlled and effected by a cam 'orequivalent device F arranged near the lower end. therenaled the base fr'am e. The can1:F,.when turned upwardly by rocking the shaft F engages against the lower side of the plate'E,

the same from the base frame to a" position as indicated by dottedlinesin Fig.

2, in which condition the magazine can easily lbe removed from the base frame. The cam is i'limitedgin its downward movementby a stop shoulderF? in thebottom of a recess-F in the base frame and against which the cam rests in its lowered position.

The operation of the cam shafts F may be effected in any desired manner, but it is proposed to employ for the purpose the usual I magazine supporting arms, G. As shown,

these arms G are provided with bosses G adapted to be applied to the opposite ends of the cam shaft F of any selected base frame, means-being provided, as will later be eX- plained, for keying the arms to the selected cam shaft, so that the magazine supporting arms may be readily applied to or removed from the required cam shaft and, when applied, serve as handles or cranks for turning it in one direction or the other. In the Open ative position of the magazine supporting arms shown by the dotted lines in Fig. 2, they rest at their inner edges upon the. oppesite ends of -the appropriateescapement bar D the arms being-provided with-pins D which enter corresponding apertures in the 'escapement bar and p-reventtheir acci'r dental disconnection from the cam shaft,

. In removing a selected magazine, the supporting arms are applied to the corresponding cam shaft F in a position substantially at right angles to the magazine and are then drawn downwardly to thelr magazine supporting position, which action-effects the turning of the cam shaft and the lifting-"of the magazine from the base frame as justdescribed. Themagazineis then slightly raised at its forward end to disengage itsfront rib a from the stop shoulders 15 and slid forwardly along the plate E onto the supporting arms. all as more fully describedin the -Mc- Namara Patent No. l,586,316. a

Coming now to the. present invention, it sometimes happens that the matricesprd. trude slightly from the forward ends of the magazines, and in shiftingthe base-frames downwardly to bring a selected magazine into operative position, these projecting matricescome into engagement with portions of the assembling mechanism and arrest the downward movement of the particular magazine from whichtheyprotrude. When this happens, the continued downward movement of the corresponding base frame (which is not arrested) will result in the disengagement of the magazine rib a from the stop shoulders. E ofthe lifting plate, leaving the magazine free to slide forwardly and downwardlyout of the machine. If this should occur at a time when the magazine supporting arms G are not in proper receiving position on the machine (and they never are during the movements of the shift frame), considerable damage is likely tov be caused by thefalling magazine. For this reason, it is proposed to lock the magazines in position upon their respective base frames so that they cannot be displaced therefrom except when the magazine supportingarms are in place. To this.

end, the invention contemplates the application'of locking means H at the opposite sides of the base frames, said locking means functi'oning normally to maintain the magazines upon their base frames.

In the present instance, the improved looking meansis shown only in connection with the uppermost magazine (the one which is the chief offender), although it may of course be applied to all of the magazines if desired. As best shown in Figs. 3 and 4, the locking means is "preferably located at each side of the base frame A and comprises a supporting plate H secured to the base frame as by screws H or other suitable fastening means, and a latch member H pivoted to the plate H as by a pin H The inner end of the latch member H is provided with a small shoulder H adapted to engage the adjacent edge of the lower plate of the magazine, and disposed between the latch member and the plate H is a small compression spring H which normally tends to disengage the latch memher from the magazine. The outer end H of the latch member extends toward the adjacent magazine supporting arm G and has a relatively flat bottom surfaceH at one side of which is a slight bevel H Operative below the outer end 1H of the latch member is a cam F which may be integral with a collar F secured to-the shaft F by a transverse pin F The collar and cam are mounted on the shaft at'the outer side of the base frame and are provided with teeth or keys F adapted to seat in grooves or keywa-ys F formed on the inner face of the supporting arm boss G Thus, the collar F 7 with its teeth or keys F constitutes the connection by virtue of which the attached arms G rock the shaft for raising and lowering the magazine supporting plate E.

The cam F is provided with a high point F which is adapted alternately to engage and disengage the lower surface H of the latch 'member in such manner that, as the shaft. is rocked to lower the cam F, said high point F will act upon the outer endH of the latch member and lock it in its engaging position with reference to the magazine;

When, however, the shaft is rocked in the opposite direction to swing the cam F upwardly and thereby to raise the magazine lifting plate: E, the cam F will release the latch member, leaving it free to be swung into its disengagedposition by the compression spring H. The shaft F will, of course, only be rotated by the magazine supporting arms G, and therefore'it will be clear that the locking means is under the control of the magazine lifting meansand-can not be re leased until the supporting arms are swung downward into position forreceiving the magazine from theb'ase frame.

It is believed that the operation of the parts will be entirely clear from the foregoing description. However, to. recapitulate,

assembling mechanism B. In this condition,

the lifting cams F are in their lowermost positions within the base frame recesses F and the cams F 6 are in their lockingpositions, maintaining the latehmembers H in engagement with the opposite edges of the magazine, and thus firmly holding the magazine on its base frame. If, now, it is desiredto remove the upper magazine A (assuming it to be in position for removal as it is in'Fig. '1), the magazine supporting arms Gare applied to the ends of the shaft F as shown by the full lines in Figs.- 2 and 3, and are then swung downwardly to the dotted line positionindica'ted in Fig. 2, thereby rocking the shaft. In the initial movement of the shaft, the cams. F disengage the latch members H to release the magazine from its base frame, andthereafter the contlnued movement of the 1 shaft causes the cam F to swing the plate E upwardly, lifting the magazine to disengage it from the escapements. The magazine is then free to he slid forwardly onto the supporting arms and removed in the customary way; In substituting a new magazine, the above operations are simply reversed, that is to say, after sliding the new magazine backonto the lifting and-support ing plate-E, thesupporting arms G are thrown upwardly to lowerthe magazine into engagement with the escapements, andqin the final movement of the rock shaft F the cams F act against the lower surfaces H'- and H to move the latchmember H? into their locking positions. i l

In the accompanying drawings, the invention has been shown merely in: preferred form and by way of example'and as applied to a machine of the class statedybut obviously many modifications and alterations may be made therein without departing from the spirit of the invention- For instanoe','the' invention in its broader aspects is not limited to machines in which the magazine must'firs t be disengaged from its escapement bank before removal, but isalso applicable to ma chines in which the esoapementsare carried by the magazine. Moreoverythe invention does not require that the release of the. magazine latches be efiected by a rotary move ment of the magazine supporting arms after their attachment to the base frame, but con; templates as well the release of the magazine latches by the direct application of the mag-' azine supporting arms to the basefra-me. These and other changes will readily suggest themselves to those slrilledin the art, and it should therefore be understood that the inembodiment except in so far as such limitations are specified in the appended claims.
