TYPOGRAPHICAL MACHINE.

Application filed May 8, 1924.: serial No. 711,772.

This invention relates to typographical machines, such as hnotype machmesof the general organization represented in Letters Patent of the United States, No. 486,532 to 0.: Mergenthaler, wherem 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 thetype characters thereon, and the matrices thereafter elevated and returned through distributing mechanism to the magazine from which they started. More particularly, 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 machine to bring one or another into operative relation to the assembling and distributing mechanisms.

The present invention is directed to certain improvements in machines of the class stated intended to simplify the construction and to facilitate the independent removal and application of the several magazines, and this without disturbing the matrix releasing escapements which remain in the machineat all times to cooperate with whatever magazines are for the time being in use.

These improvements will best be understood from the detailed description to follow.

While as above stated, the invention is intended for use more particularly in machines equipped with a plurality of shiftable magazines, it is also applicable to machines of the single magazine variety.

. Referring to the drawings: i

Fig. 1 is a perspective view of a portion of a linotype machine equipped with the inven-' Fig. 6 is a perspective view of the magazine lifting cam.

The matrices are stored according to font in the superposed channeled magazines A, three of which are shown herein but of which a greater or less number might be employed if desired. The several magazines are removably 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 b "ing any selected .magazine into operative relation to the assembling mechanism B at the lower end and the distributing mechanism C at the upper end. Each of the magazines is provided with a series of matrix releasing escapements D (Fig. t) which, when the magazine' is brought into operative )osition, are.

actuated under the control of t e keyboard mechanism inthe'usual way. In the present instance, theftwo upper base frames A are pivoted at their upper ends, as at A to a pair of plates A rising from the lowermost baseframe, so that the base frames and their respective magazines. may be separated or spread apart to permit the independent removal of any selected magazine. Such'separation of the magazines is effected by means of a hand lever J fixed to a transverse rock shaft J journaled in the lowermost base frame and provided at itsopposite ends with arms J 2 connected by lmks J? to the uppe most base frame, which. latter has suspended therefrom a pair of lifting links 5 connected to the middle base frame. lVhen in use, the

magazines and base frames occupy the close parallel relation shown in Fig. 1, but when one of the magazines is to be removed, the

handle J is drawn forwardly to cause the parts to occupy the spread apart relation shown in Fig. 2. The foregoing parts and their mode of operation are or may be su stantially as embodied in the commercial ldodel 8 linotype or as illustrated in the Kennedy Patent No. 1,896,125, to which reference may be had' for any further details.

According to the present invention, the bank of escapements for-each magazine is mounted in a fixed or set posit-ion upon the correspondingbaee frame, and means are provided iouliftin the magazine from the sse frame to dis-engage it from the escapemcnt bank preps story to removai or relDFS placement, 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.

As best shown in Fig. 4 each bank of eseapements D is mounted in the usual manner in a supporting bar or frame D, which frame (see Fig. 3) is screwed or otherwise fastened to the lower end of the corresponding base frame A. As ordinarily, the magazines are formed on their undersides with transverse 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, itis apparent that before a magazine can be removed, it must first be disengaged from its escapementbank. 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 the base frame itself and which is located in a corresponding groove or recess E formed in the upper side of the base frame. At its upper end, the plate E is pivoted to the base frame by means of a pair of hinge pins E which thus permit 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 and which thus retain the magazine in place on the plate when the latter is in its raised position. The magazine lifting and supporting plate is also formed throughout its length with a groove E" wherein engages the customary longitudinal rib a on the underside of the magazine and which acts as a guideway for the magazine as it is drawn forwardly from the machine.

in the embodiment illustrated, the swinging of the magazine lifting and supporting plate of each base frame is controlled and effected by a cam or equivalent device F aranged near the lower end thereof and fast to a transverse. rock shaft F journaled in the base frame. This cam (Fig. 6) is provided with a notched or hook shaped piece F adapted, when the cam is turned up wardly, to engage a pin F on the edge of the plate E and thus lock the latter in its proper raised position. The cam is limited in its downward movement by a stop pin F on the base frame, the plate E in its lowered position resting upon the base frame at the bottom of the containing groove E 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 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 of any selected base frame, it being noted that the rock shafts are slotted at their outer ends to receive cross pins G passed through the bosses G. By means of such pin and slot engagement, the magazine su 'iporting 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 operative position of the magazine supporting arms as shown in Figs. 2 and 8, they rest at their inner edges upon the opposite ends of the appropriate escapem-entbar D, the latter being provided vith pins D which enter corresponding apertures in the arms and prevent their accidental 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 their magazine supporting position,which action effects the turning of the cam shaft and the lifting of the magazine from the base frame as just described. The magazine is then slightly tilted atits forward end to disengage its front rib a from the stop shoulders E and slid forwardly along the plate E onto the supporting arms as indicated by the dotted lines in Fig. 2, the magazine being guided in its forward sliding movement by the engagement of its central longitudinal rib a with the groove or guideway E. The magazine is provided on its underside, as shown, with additional transverse ribs which enable it to be arrested in different longitudinal positions on the lifting and supporting plate when desired. To prevent any possible injury to the escape ments and to assist in supporting the magazine during its removal the escapementbars D are each formed at opposite ends with upstanding projections D" and D arranged substantially at the level of the track portions of the magazine supporting arms.

It will be observed that when the magazines are elevated out of engagement with their corresponding escapements, the contained matrices would be free to pass therefrom unless they were first locked therein, and hence means are provided to prevent the operation of the cam shafts until the matrices have been locked in the magazine. In the present instance (see particularly Figs. 3 and l) such means comprise, for each magazine, a centrally pivoted latch H mounted in the left hand projection D of the escapement bar, and upright arm H fast to the end of the cam shaft F. The latch is normally held in the path of the arm by a spring H so as to lock the cam shaft against rotation, but the latch is arranged to be disengaged from the arm by the usual matrix locking rod H which is inserted through the edge the escapements preparatory to removal. In

place of the detachable matrix locking rod H the magazines may be provided with permanent locking rods, such as shown and described in the Kennedy Patent No. 1,347,- which are shiftable in an endwise direction to lock or unlock the matrices.

It is believed that the operation of the parts will be entirely 'clearfrom the foregoing description. However to recapitulate, it may be stated that in removing any selected magazine, the matrix locking rod H is illSt inserted through the edge of the magazine in the manner then the supporting arms G are applied to the cam shaft F and drawn downwardly to swing the plate E upwardly and lift the magazine out of engagement with the escape merits, all as indicated by thefull lines in Fig. 2. The magazine is then free to be slid forwardly onto the supporting arms and removed in the customary way, as indicated by the dotted lines in Fig. 2. In substituting a new magazine, the above operations are simply reversed, that is to say, after sliding the substitute magazine back onto the lifting and supporting plate E, the supporting arms G are thrown upwardly to lower the magazine into engagement with the escapements, which of course remain in place upon the base frame, and the matrix locking rod l f 'then withdrawn to permit the matrices to be released from the magazinewhen in use. .In the present instance, the magazines are spread apart by the operation of the hand lever J to facilitate the removal'of the two lower magazines, but this .of course would not be necessary if the space between the magazines were greatenough to permit the required lifting of an underlying magazine without interference with the overlying magazine. The employment of the magazine separating means is advantageous, in that the magazines and their base frames may be arranged inclose compact relation as shown in Fig. 1.

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 stated, but obviously many modifications and alterations may be made therein without departing from the spirit of the invent-ion. It should be under-' stood therefore that the invention is not limited to any specific form or embodiment can spring H just described, and

cept in so far as such limitations are specified in the appended claims.
