Application tiled OctoberV 10, 1914. Serial No. 866,069.

T0 all whom it may concern:

Be it known that I, JOHN-W. GRAHAM, a citizen of the United States, residing at Hinton, in the county of Summers and State of West Virginia, have invented new and useful Improvements in Typographical Machines, of which the following is a specification.

This invention relates to typographical machines such as linotype machines of the kind disclosed in the patent to O. Mergenthaler, No. 436,532, wherein circulating matrices are released from magazines in the order in which their characters 1@are to appear in print and then assembled in linev together with expanding spacers, the composed line being transferred to'l the face of a`mold, the latter beingv lled with molten against the matrices which produce ty'pe characters thereon, the matrices being .thereafter elevated and returned through a distributing mechanismto 'the' magazines from which they started.

'The object of the present invention is to provide in' connection with a suitable supporting frame, a rack in which any desired number of matrix magazines may be placed and removed or interchanged at will, the Said rack being shiftable up and down to bring the magazines' into proper alinement with the throat and guide plate or race and relations charge ends are closer way. The magazines are supported in the shiftable rack in such a way that their distogether than their receiving ends and in order to shift said rack it is expedient to first shift the throat and guide plate out of the path of movement of said rack and after the rack has been' shifted, again move the" throat and face plate back to their operative positions' to the appropriate magazine/ Another object of the invention is to 'provide novel means for counterbalancing and shifting the magazine rack and also means for locking and unlocking' said rack so as to maintain the proper relationship between each magazine and the throat and guide pla-te.

lVith the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed. ln the accompanying drawings z--Figure 1 is a side elevation of a sufficient portion of zines.

a typographical machine to illustrate the present mvention, themagazine rack being shown at the lower limit of its movement. Flg. 2 is a similar view. vshowing the rack elevated. Fig. 3 is a view taken from the opposite side of themachine. Fig. 4 is a fragmentary elevation, illustrating the latch operating mechanism and the means for shifting the guide plate. F ig. 5 is a similar view showing the guide plate shifted ont of the path of movement of the rack. Fig. 6 is a fragmentary side elevation showing the means for shifting the throat. Fig. 7 is a similar view showing the throat shifted out of the path of the magazine rack. Fig. 8 is a longitudinal section through one side of the machine on anenlarged scale showing the latch operating mechanism. Fig. 9 is a similar view showing the latch pins withdrawn from the rack fra-me. Fig. 10 is a fragmentary elevation of the nested rock shafts and the operating means therefor. .Fig l1 is a fragmentary end' view of a portion of the rack, showing the means.

for suppprting and adjusting the maga- Fig. tional view showing the escapement mechanism for the matrices.

Referring to the drawings A generally designates the `frame of the machine and B the magazine rack which comprises the ,parallel bottom bars 1 the front and rear end or cross bars and 3, respectively, and the oppositely arranged magazine supporting bars l which bear `a fixed relation to the 12 is a detail fragmentary sec-.1

bai-s2 and 3 thus'forming a rack frame, the

severa-l bars of to each other. Each of the supporting b'ars 4 is preferably formed, of angle iron as indicated in Fig. l1, the bottom flanges 5 thereof formi-ng supports forthe magazines indicated at a', I), c, d, c and The'maga.- zines may be adjusted to properly aline them with `the throat C and guide plate or race way l) by means of set screws 6 as in- -dicated in Fig. 11.

.of the usual shape in common use, being narrower at their discharge ends than at their rear ends, and tht` bars i correspondingly converge to,- ward the front of the machine. This en ables the magazines to he slid rearwardly out' of engagement with their supporting bars and also held againstmovement in the opposite direction by said bars.

The magazines are which bear a fixed relation The means for shiftingthe rack will now l be described. 7 designates a 'rack shifting hand lever which may be arranged at either the right or left hand side of the machine,

said lever being fast to a tubular rock shafty 8 'which is best illustrated in Fig. 10, said rock shaft being journaled in bearings in plate D, when the rack is latched or locked by the means hereinafter described.

The magazines are arranged like the blades of a fan, the forward or discharging ends thereof being arranged closer together than the rear or receiving ends as shown in Figs. 1, 2 and 3. Therefore, in the shifting of lthe rack, the rear end thereofmust move faster than the' forward end. ln order to accomplish this, employ asystem of levers as follows. A lever 12 is pivotally attached at one end at the point 13 to thev frame Another lever 14 is pivotally attached at the point 15 to the frame A. The opposite eX- tremities of the levers 12 and 1d are connected by a linklli. To the pivot 17 connecting the adjacent ends of the lever 12 and link 16 there is pivotally attached one end of a link 18 the opposite extremity of which is pivotally attached at 19 to the adjacent bottom bar 1 of the rack. The arrangement of levers and links referred to is duplicated at each side of the machine as will be apparent by comparing Figs. land 2 with Fig. 3. This produces' an unequal movement of the front and rear ends of the rack thereby compensating for the unequal distances between the front and rear ends of the magazines.

rl'he mechanism for locking and unlockingr the rack comprises a rock shaft 20 which is housed or nested within the tubular rock shaft 8 as shown in Fig. 10. On opposite ends of the rock shaft 20 are cams 21 and extending from one of said cams is a pin 22 to which is connected the lower extremity of a cam operating rod 23 which extends upwardly on one side of the rack shifting levcr 7 where it is connected to a latch 2l the point of which may be thrown into and out of engagement with any one of'a serios of notches 25 in a curved rack bar 26 secured to the machine frame in fined position. ('onncctcd to the upper extremity' of the` latch slv is another rod 27 which is in turn attached to a` bell crank lever 23 fulcrumod at 2S) on the rack shifting lever 7 above described. The handle ends of both levers 7 and 28 are arranged close together so that both may be masses grasped and operated simultaneously as will be apparent from Figs. l and 2.

Referring now tolligs. 4c ando, it will be observed that each cam 21 coperates with a roller 30, on the lower end of a plunger 31 formed with slots 32 to receive guide pins 33 on the machine frame. 31 designates a latch puller in the form of a bar extending along side of the uppermost magazine, said bar being adapted to be shifted lengthwise by means of a pin 35 projecting from the bar 31 and entering an oblique slot 36 in the plunger 31 so that as said plunger 311 is moved by the cum 21, the latch puller 31 will be shifted in one direction. 37 designates a retracti-ng spring for moving the plunger 31 in the opposite direction and maintaining the roller 30 in engagement with the cam 21.

Each of the bars 2 and 3 is provided Withlongitudinal series of holes 38 to receive latch pins 39 which pass throughlioles in the frame A and are pressed inwardly by means of latch springs 40 as best illustrated in 1-`igs. 8 and 9. Each latch puller 34 is provided with a` plurality of wedge or cam faces 41 which operate against the heads 42 of the latch pins 39 so as to draw said pins 39 out -of holes 38 when said latch puller is moved endwise in one direction by the mechanism previously described. This effects an un locking of the rack so that itmay be subse quently elevated or depressed by the rack shifting lever 7. The latch puller 34 also opcrates to shift the throat C out of the of the rack and magazines, the end o the puller bar 34 being concaved or notched as shown at 13 in Figs. (i and 7 to engage a pin or stud 44 on the adjacent side of thel throat C. Therefore, when the puller bar 34.- is 0perated by the plunger 31 and cam 21, the throat C is swung outwardly on its pivotal connection at the point stel with an entcnsioi` l5 ofthe machine frame A until it assumes ath the position illustrated in Fig. 7, said throat will be observed that the guide plate D is' provided with an arm 47 having guide slots 48 which receive guide pins 4S) on the framev A. The arm $7 has a pin 50 extending laterally therefrom through an oblique slot 51 in the plunger 3l and therefore when the plunger 31 is thrust upwardly by thc cam 21 to unlatch the rack frame, the arm 47 is operated upon by said plunger to shift the guide plate or race way D from its oper ative position shown in F ig. 4 to its inoperative position shown in lfig. 5.

In Fig. 12 I have illustrated the csr-apcment mechanism for the matrices, 52 desighating one 'of the run Ways of a magazine and 53 matrices therein. 54 designates an escapement lever which is held in one position'by means of a sprin 55.' .The escapement lever is provided with a lip 56 at one -end which isengaged by a corresponding lip on a trip 57 which is adapted to be operated by one of a series of trip rods 58 at the front of the machine, said trip rods 58 being operated in the usual manner. A bank of escapements is employed at the discharge end of veach magazine, said escapements being raised and lowered with their' respective .magazines The trip rods 58 pass through guide openings in a cross bar 59 connecting.

the arms 47 above referred to so that the upper extremities ofsaid rodsS are .shifted out of the way simultaneously with the guide plate or race yway D as shown by comparison of Figs. 4 and 5. The arms 47 are drawn inwardly by the retracting springs 60.

The rear end of the magazine rack is controlled directly by the bottom bars l of the rack which are in turn controlled by the lifting arms 10. The front end of the rack is controlled by links 61 which are pivotally connected at 62 to the front end or cross bars 2 of therack, the links 61 being pivotally connected at v63 to the extremities of the levers i4 at the points 64.

65 designates counterbalancing springs connected at one end' to the rack at the point 66 and at the opposite end at 67 to extensions or arms 68 .of the frame A. E designates the usual distributer arranged above the throat Cso as to discharge into the same.

From the foregoing description taken in connect-ion with the accompanying drawings it will now be understood that when the operator desires to shift the rack so as to bring any particular magazine into line with the vthroat and guide plate or race way, he grasps the lever 7. and at the same time he grasps the lever 28. He first operates the lever 28 to withdraw the latch pins 39 and shift the throat C and guide plate D out of the way. I-Ie then moves the lever 7 until the desired magazine is in its proper place.

Thereupon he releases the lever 28 which serves by means of the latch 24 to lock said lever and also to release the latch pins 39 permitting them to enter the proper holes 38 in the bars 2 and 3 of the rack. Simultaneously therewith the throat C and guide plate or race way D are restored to their operative positions. Any variation between the holding position of the latch 24 and the holding positions of the latch pins 39 may be compensated for by adjusting the turn buckle 11 above referred to. The magazinesare usually wider at their receiving ends than at their discharge ends, imparting thereto a wedge shape, and accordingly the rack' frame is of the same general' shape in plan, the supporting bars 4 converging from their rear toward their front extremities. This facilitates the removal and replacement of the magazines.

It will of course be understood that the rack may be made of any desired size and` capacity according to the number ofmagadetails of construction may be resorted to without departing from the principle or sac- .ricing any of the advantages of the invendischarge ends are at less distance apart than their receiving ends, and manually controlled means for unequally raising and lowering the front and rear of said rack.

2. In a typographical machine, the combi.-

to be used therein aiid'that various changes in the form, proportion and minornation of a plurality of removable magazines, a multiple magazine rack on which the .magazines are supported so that their discharge ends are at less distance apart than -their receiving ends, manually controlled means for unequally raising and lowering the front and rear of said rack, and counterbalancing means for said rack.

3. In a typographical machine, the combination of a plurality of removable magazines, a multiple magazine rack on which the magazines are supported so that their discharge ends are at less distance apart than their receiving ends, manually controlled means for unequally raising and lowering the front and rear of said rack, and means for locking and unlocking said rack.

4. In a typographical machine, the combination of a plurality of removable magazines, a multiple magazine rack on which the magazines are supported so that their discharge ends are at less distance apart than their receiving ends, latches for locking said rack, a manually operable lever and connections or shifting said rack upand down, and other connections associated with said leyer for operating said latches.
