June 24, 1933, -Serial No. Divided and this application March 16,181. In Great Britain and Germany October 21, 1933 15 Claims. (01. 199-46) This invention relates to typographical machines, such as those of the general-organization represented in Letters Patent of the United States No. 436,532 .to O. Mergenthaler, wherein circus lating matrices are released from a magazine in the order in which their characters are to appear in print and'then assembled in line, thecomposed line-transferred to the face of the mold, the

moldfilledwith molten metal'to form a slug against the matrices which produce the type char- 'actersthereon and the matrices thereafter, elevated and "returned through distributing mechanismto'the magazine from .Whichthey started. More particularly, it relates to machines where'- in=the magazine is pivotally mounted in the machineirameand ismovabl'efroma position parallel'wlth the magazine supporting frame; wherein it cooperates with the matrix releasing escapenients'whichremain inth'emachine at all times, to ap'osition clear of the escap'ementato facili- "tate the'removal *of'th'e magazine and its replacerfrrentby a'magazine containing a-different matrix ont.

H "The presentinvention is directed to certain improvements in machines of the class-stated, and-intended to simplify the construction and f'acilitate'the locking or thematrices'in the magprior to'the removal thereofflfrom-the'machine. 'To this'end, the magazine containing the il'iiferent fontswith-which the machine-is adapted equipped are provided I each with a' matrix 'toekingbar'whichis automatically shifted to active-position as the magazine is separated from the escapement mechanism to facilitate its removaL and the locking bar of the substitute magmine aiitomatically 1 shifted to inactive 'position as such magazine isbrought into engagement with the escapement mechanism to permit the operation thereof in the usual manner to release thermatrices.

'iInwanother 10f its aspects, the invention comprehends arrangement whereby i the. matrices in=themagazine on the machine may be transie'rred to' a storage magazine andother matrices transferred from a=secondstorage magazinerto the main magazine without removing 'the'latter from E the i machine.

This application is a division of my copending application serial No. 677,417 filed June '24, 193-3.

' :Reerring to the drawings:

1 is a side- -elevation of a-portion of alinotype machine showing a magazine in apartially raised position, the means for raising and lowfiring the -magazine and the 2 means for automaticallry operatingthematrix lock; 7

2 is a side elevation similar to Fig. l, with I the parts innormal position;

Fig.3 is'a side elevation similar to Fig. 1, showing the "parts in aposition just prior to raising the magazine from the frame;

' Figs. 4 and 5 are partial front elevationsofthe parts shown in Figs. 1 to 3; I Figs. 6 and? arepartial sectional views on lines 6-'6,and11-+'l of'Figs. 2 and .1, respectively; Fig; 8 is a side elevation of. a portionof the machine, showing the devices .for transferring matrices'from and to the main magazine without removing the latter from. the machine; Fig: 9 is a partial front View of the parts shown inFig. 8; and I Fig. '10 is 'a section, partially broken away, on line |0l0'of Fig-Q8. p 1'. The matrices are stored'in a channeled mag azine A resting on a base frame A and pivotally mounted inthe machine topermit movementinto so and out of operative position with the usual assembler entrance or raceway (not shown blltpO sitioned as usual atthe lower end of the magazine). The magazine in its operativeposition cooperates with a bankpf escapements A fixed to the base frame and operated in the usual way froma keyboard mechanism to release the mat rices one at aatime for stacking in the assembler (not shown) to form a composed line. There'- after'the' line is transferred to the first-elevator or transporter which descends to present the com posed line to1the mold,'the mold advanced into close contact with thematrix line, the mold-filled with molten metal to form a slug against the matriceswhich produce the type characters therei r on, and thematricesthereafter elevated. and returned through a "distributing mechanism .'po'si'- tioned at the upper end-of the magazine Al'tO the respective channels of the magazine from which theyzstarted. L 40 Inorder that different-fonts-may be used, with the machine, the magazine A, as previously stated, "is pivotally:mounted in the machine -so that it may be raised from its normal position, parallel to the magazine-supporting,frame A to effect its removal and replacement by a magazine containing a different font. When the mag: azine. A .isin'its'normal position, the matrices, of course, are held thereinby the escapementpawls which cooperate with the upper projecting ears .of the matrices to effect their' release one at a time, but when the magazine A is separated'from the escapements A some means mustbe provided for locking the'matrices to prevent them from spilling out of the magazine.

As more fully described in my Patent No.

sition shown in Figs. 2 and 4, with hook portions a engaging at opposite ends of the customary forward transverse rib a on the undersideof the magazine to hold the latter securely in position.

The magazine supporting frame A is" provided with a central magazine lifting and supporting plate A (Fig. 8) pivoted at its upper end to the its lower end, ders a normally engaged with the rib a and which thus retain the plate A when the latter is in its raised. position.

In the embodiment illustrated, the swinging of the magazine lifting and supporting plate A is controlled and effected by a cam a or equivalent device arranged near the lower end thereof and fast, to the transverse rock shaft A journalled in the base frame A Thus, when thehand levers A A5 are pulled forwardly, the magazine is first released from the magazine frame by the disengagement of the hooks a with the rib on the magazine, and the magazine raised by the engagement of the cam a with the magazine v supporting plate A this action resulting in the se paration ofthe magazine from the escapements A When the. magazine is separated from the escapements, the matrices are prevented from spilling out by a locking bar A extending transversely of the magazine, and provided with a series'of depending teeth a at its front edge, which are adapted to stand across or in front of the lower mit the release of zine.

The transverse movements of the locking bar are effected automatically by a pair of cams a", a, one mounted on each of the hand levers A A, the cam a on the left having a surface a slopinginwardly toward the side of the magazine and which engages the left end of the locking bar surface are complementary in nature, the slope of the cam surface a on the right providing the necessary clearance for the locking bar as it is actuated to the right by the locking cam a", and the slope of the surface a of the latter cam providing the necessary clearance for said bar when it is actuated to the left under the influence of the unlocking cam all.- i p As shown in Figs. 6 and 7, the rear faces of the teeth a are bevelled, so that as they are projected across the magazine channels by the movement erative relation with magazine in place on'the of the locking bar A to the right, they will push the matrices rearwardly a slight distance, and thus provide clearance between the matrices and the escapements as the magazine is removed from or replaced in the machine, The bevelled surfaces also facilitate the cooperation'of the teeth with the matrices.

, In order to maintain the bar A in its locking position when the magazine is removed, the latter is provided at the right with a pivoted locking pawl a arranged to enter a notch a in the upper edge of the .bar A when the latter is in its locking position (Figs. 1 and 7). The lower portion of the pawl a engages on the top of the escapement frame A when the magazine is in opthe latter (Fig. 2), thus maintaining the pawl in its inactive positon against the push of a spring pressed pin a banking on the rear edge thereof. ,Just prior to the disengagement of the magazine from the escapements, the locking bar A is actuatedjto locking position, bringing thenotch a in registry witli the pawl a (Fig. 7), so that as the magazine is raised from the escapements and the pawl freed, the latter is pushed forwardly. into thenotch by the pin a thereby retaining the bar A in lock ing position. When the magazine is again brought into cooperative relation with the escapee ments, the pawl a banks uponthe top of the escapement frame A and thereby is withdrawn from the notch a 'to release the locking bar.., f I

In Figs. 8 to 10, there is shown an arrangement whereby the matrices in the magazineonfthe machine may be transferred, to a storage maga zine and other matrices transferred froriianother storage magazine to the main magazin'elwithout removing the latter-"from the machine.

The storage magazines A A l are each pro-l vided with channels corresponding with those of the main magazine A, a pair of transverse ribs a a atthe bottom of the magazine, projecting beyond the lateral edges thereof, 'a shorter transverse rib a at the leading edge of the magazine and the usuallocking bar A for preventing supporting frame (Fig. 8), a, pair of supporting surfaces are presented upon which the auxiliary magazine rests with its channels, in alinement with the corresponding, channels of the main magazine. Each of the levers is further, .pro:- vided with a retaining lug a -at its forwardend arranged to engage the lower transverse, rib al, to maintain the auxiliary magazine in, position on the supporting levers.

The machine is also provided withiaflhinged magazine entrance channel Jl between the distributor mechanism and the entrancerend'of' the magazine 'A, which may be turned downwardly out of the way of the auxiliary magazine A from which the matrices are to be transferred to' the main magazine; The auxiliary magazine A is held in position to transfer matriceslto the magazine A by a pair of lugs a l, one (arranged at each of the upper corners of themagazin'e sup"- porting frame A and upon which the front edge of the auxiliary magazine rests with" the transverse rib a banking against the rear fa'cesfof the lugs, and by a pair of brackets'A supported by the distributor frame at the opposite ends thereof. The bracketsare each providedl attheir iii" rear ends with a spring actuated dog a arranged to engagebeneath-ithe upper. transverse rib a of the auxiliaryv magazine, andat the ends there-- of to maintain the magazine in aiposition,-where its channels aline with the corresponding channelsof the main magazineis. Thus, in order to. place the'auxiliary. magazine-1A in position it is necessary only to rest the front edge thereof on the magazine supporting frame'A and push therear portion of thexmagazine'upwrtilengaged by the spring actuated dogs e .yInrorderi toitransfer the matrices from the main magazine Atothe auxiliary storage magazine, A the -matrix=-lock of the-latter is first looked andthe matrix lock of the main :magazine unlocked, whereupon the. matrices. willvslide :out ofthe channels of the ,main; magazine. into the corresponding channels of the :iauxiliary magazine-.- The lockof the main magazine is then looked, and that of the uppergauxiliarymagazineA k unlocked, whereuponthematrices will,

slide fromathe channels ofthelatter into the corresponding channels of themain magazine.

The-storage vmagazines are then removed and the mainqmagazine lowered to its normal-positionby the rearward movement'of the levers A Theadvantage of the-auxiliary magazines re-, sides in thefact thattheymay befmade cheaply, thus obviating the-necessityfor a number of main magazines correspondingvto the different fonts desired tobe'usedwith the machine. They are particularly desirable in a machine such as that described in my copendingapplication, Serial No. 677,417, wherein the main; magazine is much wider than usual being designed chiefly-for use withfhead letter? matrices -and consequently more expensive than standard magazines, 1 i, V In ,view of the previous descri tionyit is be; lieved the invention will be. readily. understood without entering. into a further description of; theoperation of the machine ,In the accompanying drawings the invention hassheenoshown merely by way ofexample. and in preferred form, and obviouslymany variations andfmodificationsfmay be made therein which will stillbe comprised within its spirit. It is to be understood, therefore, that the invention is not limitedto, any specific form-or embodiment, except insofar as such in the [appended claims.
