Application filed January 17, 1914. Serial No. 812,779.

1 '0 all whom it may concern Be it known that we, WILLIAM E. Beu- TRAM and THOMAS S. HUMANS, citizens of the United States, residing at (1) Brooklyn and (2) Hempstead, in the counties of (1) Kings and (2) Nassau and State of New York, have invented new and useful Improvements in Typographical Machines, of which the following is a specification.

The present invention relates to improvements in typographical machines and more especially to those of the linotype class and of the type adapted to contain a plurality of magazines, any one of which may be brought into use. One of the primary objects of this invention is to provide improved means for shifting the magazines to bring the desired one into operative position which means enables the use of a. simple form of matrix controlling escapement. Another object is to provide improved means for mounting the magazines whereby the movements or operations of bringing the different magazines into position for use are facilitated. Other objects are to provide means for automatically accommodating the magazine entrance to the movements of the magazines and for preventing shifting of a magazine until the matrices belonging thereto have been distributed into it.

Tothese and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawings Figure 1 is a side elevation of the upper portion of a machine of this class and embodying the present, invention;

Similar parts are designated by the same reference characters in the several views.

The preferred embodiment of the invention is shown in the accompanying drawings and will be hereinafter described in detail. It is to be understood, however, that the invention is not restricted to the precise construction shown or to the particular number of magazines employed as equivalent construction within the scope of the claims at the end of the specification may be used.

In the present instance the upper portion of the main frame 1 of a machine of the linotype class is shown, this main frame usually known as the column having a vertically extending arm 2 bolted or otherwise secured rigidly thereto. A cylindrical member 3 which we term the barrel extends horizontally from one side of the arm 2 and its outer end is formed with a slot 4. This slot is adapted to receive a key or rib 4 formed on a cap 5, the latter being secured to the slotted end of the barrel 3 by screws 6 or equivalent means. An arm 7 similar to the arm 2 is mounted on the outer end of the barrel 3 and it is secured to the cap 5 by the bolts 8 and dowels 9 or equivalent means. The arms 2 and 7 serve to support the distributer mechanism, the beam 10 carrying the distributor bar 11 being secured to the upper ends of these arms. A sleeve 12 is journaled to rotate on the barrel 3 and said sleeve has a bracket 13 rotatably mounted thereon. This bracket provides a guide, preferably of cylindrical form, to receive a slide or plunger 14, and this plunger supports the carrier for the magazines. In the present instance a magazine yoke is mounted on the upper end of the slide or plunger 14:, the same embodying a base plate 15! and a pair of side plates 16. Magazine frames 17, 18 and 19 are supported by the magazine yoke, each magazine frame being provided with a matrix containing magazine 20. The magazine yoke is movable at right angles to the planes of the magazines by the axial or longitudinal movement of the slide or plunger 14:. This movement of the magazine yoke is guided not only by the slide or plunger let and the cooperating bracket 13 but also preferably by a pair of brackets 21 arranged to cooperate with the respective side plates 16 of the magazine yoke, the magazine frames and the magazines thereon being movable downwardly between these brackets.

In the construction shown, the upper magazine frame 17 is secured immovably to the side plates 16 of the magazine yoke while the two lower magazine frames 18 and 19 are slidablc relatively to the magazine yoke during the operations of bringing the magazines on either of these frames into operative position or removing such magazines from operative position to enable the upper magazine to be brought into position for use. For this purpose the magazine frames 18 and 19 are guided to move longitudinally with respect to the magazine yoke, the frame 19 having a longitudinal rail 22, shown in Fig. 2, which is slidable in a groove 23 formed in the base member or plate 15 of the magazine yoke and the frame 18 having wings 24 projecting outwardly from its opposite sides and sliding in suitable grooves in the side plates 16 of the magazine yoke. Escapements 25 are arranged at the lower forward ends of the magazines to control the delivery of matrices therefrom, the escapements belonging to any magazine in position for use occupying a position to .be rocked or actuated by the escapement actuating rods 26, the latter being operated commonly by a keyboard. The matrices upon being delivered from the magazine pass over the guide 27 and then pass to the matrix assembling mechanism in the usual way.

Assuming that the parts occupy the position shown in Fig. 1 and it is desired to bring the middle magazine on the frame 18 into operative position, the magazines are first lifted bodily by upward movement of the slide 14 and the magazine yoke which carries the magazines, the lower magazine frame 19 is then shifted rearwardly until the magazine thereon is clear of the escapement actuating rods 26, whereupon the magazines are lowered bodily by downward movement of the slide or plunger 14 and the magazine yoke, the escapements of the magazine on the middle frame 18 being thereby brought into operative relation with the escapement actuating rods 26. In order to bring the magazine on the upper frame 17 into position 'for use, the magazines are lifted bodily as before by upward movement of the slide or plunger 14 and the magazine yoke thereon, then sliding the middle magazine frame 18 rearwardly until the escapements of the magazine on this frame are clear of the escapement actuating rods, whereupon the magazines are lowered bodily by descending movement of the slide or plunger 14 and the magazine yoke, thus bringing the escapements of the magazine on the upper frame 17 into operative relation with the escapement actuating rods 26. The parts are shown in this position by the full lines in Fig. 3.

The present invention provides improved means for shifting the magazines in the manner'described whereby any one of the magazines may be brought into operative position. In the construction shown, the lifting and lowering of the magazines is effected by a cam 28 which is keyed on or otherwise fixed to the rotatable sleeve 12, this cam having a set of three steps 28, 28 and 28 "corresponding to the number of magazines employed. An arm 29 is secured rigidly to or forms part of the bracket 13, this arm having one end of a lever 30 pivoted thereto and the opposite end of said lever is forked and carries rollers or projections 31 which bear against lugs 82 arranged at the under side of the magazine yoke. This lever 30 is provided intermediately with a roller 33 which cooperates with the periphery of the cam 28. The steps 28*, 28 and 28 on the cam 28 are located at different distances from the center of rotation of the cam and hence rotation of the cam will cause the lever 30 to move the magazine yoke up or down according to the direction of rotation and to support the magazine yoke in three different positions corresponding to the operative positions of the magazines. Raised portions 28 and 28 are formed on the cam between the cam surfaces 28" and 28" and 28 and 28 respectively whereby during rotation of the cam 28 to remove either of the two lower magazines from operative position and to bring one of the higher magazines into operative position, the magazine which is to be removed from operative position is first lifted in order that it may be shifted rearwardly to clear the escapement actuating rods.

The shifting of the two lower magazine frames 18 and 19 is effected by a cam 34 rotates.

fee

which is also keyed on or otherwise fixed to the sleeve 12. This cam has three steps 34', 34" and 34" located at different distances from the center of rotation of the cam, and a roller 35 is arranged to cooperate with the different steps of the cam as the latter Said roller is mounted on the end of an arm 36, said arm being fixed to a rock shaft 37 and a pair of arms 38 are fixed to said rock shaft and are positioned to cooperate with a pair of rollers or projections 39, one upon each side of the lower magazine frame 19. Fig. 8 shows the arms 38 in their two extreme positions, this figure also showing the shifting relation of the rollers 39 with respect to the arms 38, the shaft 37 supporting the arms 38 being mounted on the bracket 13, as shown in Figs. 1 and 3. \Vhen the magazine on the lowermost frame 19 is in operative position, as shown in Fig. 1, the magazine yoke will be in elevated position and the cams 28 and 34 will occupy the positions shown in Figs. 4 and 8 respectively. In order to bring the middle magazine on the frame 18 into operative position, the barrel or sleeve 12 hav ing the cams 28 and 34 thereon is rotated in a clockwise direction. This will bring the raised portion 28 of the cam 28 upon the roller 33, thus raising the magazine yoke sufliciently to lift the escapements of the magazine on the lower frame 19 from engagement with the escapement actuating rods 26, and continued rotation of the barrel or sleeve 12 will bring the intermediate portion 34 of the cam 34 into engagement with the roller 35, thus rocking the arms 38 rearwardly, and these arms acting on the rollers 39 of the lower magazine frame 19 will slide this frame and the magazine thereon rearwardly, thereby carrying the escapements on this magazine clear of the escapement actuating rods. Furtherrotation of the barrel or sleeve 12 will bring the intermediate portion 28 of the cam 28 into engagement with the roller 33, thereby lowering the magazine yoke and bringing the magazine on the middle frame 18 into operative position with its escapements in cooperative relation with the escapement actuating rods. The magazine on the upper frame 17 is brought into operative position by another step in the rotation of the barrel or sleeve 12 in'a clockwise direction, this movement turning the cam 28 into a position first to bring the raised portion 28 into engagement with the roller 33, thereby raising the magazine yoke and lifting the escapements of the magazine on the middle frame 18 from engagement with the escapement actuating rods 26, and while the roller 33 is traveling over the raised portion 28 of the cam 28 the roller 35 is traveling from the middle portion 34* to the high portion 34 of the cam 34. Further rotation of the barrel or sleeve 12 brings the low portion 28 of the cam 28 into engagement with the roller 33, and the magazine yoke is then lowered into the position shown in Figs. 3 and 6, thereby bring ing the magazine on the upper frame 17 into operative position with its escapements in cooperative relation with the escapement actuating rods. The second step in the rear ward movement of the arms 38 which occurs during the travel of the roller 35 from the intermediate portion 34 to the high portion 34 of the cam 34 brings the arms 38 into the position shown by the dotted lines in Fig. 8. This movement of the arms 38 serves to slide the middle frame 18 and the magazine thereon rearwardly preparatory to the lowering of the upper frame 17 into operative position. In the construction shown, the rearward shifting of the middle frame 18 is effected by movement derived from the lower frame 19, the lower frame 19 being provided with upwardly projecting lugs 40 at the opposite sides thereof which come into engagement with outwardly extending projections 41 on the opposite sides of the middle frame 18 during the second step in the rearward movement of the lower frame 19, the rearward movement of the lower frame 19 being thereby transferred to the middle frame 18 whereby the magazine on the middle frame is drawn rearwardly preparatory to the lowering thereof.

In order to insure accuracy in the positioning of the different magazines and thus avoid the expense of precision in the forming of the cams, positioning lugs 42 are provided at the opposite sides and near the front of each n'iagazine frame, these positioning lugs being arranged to rest upon lugs 43 formed on the side brackets 21 as the respective magazine is brought into operative position. The rear portion of each magazine as it is brought into operation is positioned correctly with respect to the distributing mechanism by lugs 44 which are provided at the opposite sides of the magazine frames and are arranged to rest upon corresponding stops or lugs 45 which are formed on the upper side brackets 46, the latter being secured to the inner sides of the respective distributor bracket arms 2 and 7. In shifting the magazines it has been pointed out prcviouslytl'iat they occupy a position above their normal operative position while sliding {forwardly or rearwardly and this enables the positioning lugs 42 and 44 to clear their respective stops 43 and 45.

The magazine entrance 47 is pivotally mounted at 48 on the upper side brackets 46. In order to permit the magazines on the middle and lower frames 18 and 19 to slide rearwardly, as hereinbefore described, the distributer entrance must be swung rearwardly out of the way of the rear end of the magazine which is to be shifted. In the construction shown, the distributer entrance is shifted automatically by a cam 49 which latter also keyed on or otherwise fixed to the rotatable barrel or sleeve 12. This cam has a cam groove which comprises three sections 49, 49 and 49 and a roller or projection 50 operates in the cam groove. This roller or projection is carried by an arm 51 which is fixed to a shaft 52 and this shaft has an arm 53 fixed thereto and the latter is connected to a rod 54:. The upper end of this rod is arranged to cotiperate with a projection 55 on the channel entrance 47. Rotation of the cam 49 causes the roller or projection 50 to engage successively in the sections 49, 49 and 49 of the cam, and in moving from one section to the other the parts are shifted from the normal position indicated by the full lines in Fig. 9 to the position indicated by the dotted lines in said figure, and when the channel entrance is in the dotted line position, it is swung rearwardly to clear the magazine which is about to be shifted rearwardly. In order to permit the channel entrance to be swung down or in open position manually, the pin or projection 55 engages in a slot in the upper end of the rod 54, this slot having an offset portion 56 in which the p n normally engages and is held in such pos1ti0n under the tensionof a spring 57, and a straight portion 58 of the cam will permit manual opening and closing of the channel entrance after the rod 54 has been pulled rearwardly against the tension of its spring 57 to bring the pin or projection 55 into the straight portion 58 of the slot.

Operation of the mechanism above described to effect shifting of the magazines to bring the desired one into posit-ion for use is accomplished preferably by means located adjacent to the operators position at the machine. In the present instance a worm wheel 59 is fixed to the rotatable barrel or sleeve '12 and it coiiperates with a worm 60, the latter being fixed on a shaft 61 which extends forwardly toward the operators seat, the rear end of the shaft 61 being journaled in a bracket 62 which may be fixed to the lower end of the distributer bracket arm 7. The forward end of the shaft 61, is preferably provided with a hand wheel, 63 and also with a crank handle 64 whereby the shaft 6]. may be turned. In order to prevent shifting of the magazines before the matrices belonging to the particular magazine have been distributed thereto, a lock is provided which, in the construction shown, embodies a collar 65 which is splined on the shaft 61 and has a tooth 66 adapted to engage in a notch in the bracket 62. A spring 67 normally operates on the collar 65 to hold it in locked position and thereby prevent rotation of the shaft 61. The collar 65 which is slidable longitudinally on'the shaft 61 to engage and disengage the toothv 66 thereon relatively to the notch in the bracket 62 is provided with a shifting rod 68, this rod being con nected at its forward end to a lever 69 which is fulcrumed at 70 on the hand wheel 63, and the handle 61 is movable in a direction longitudinally of the shaft 61 and has a. plunger 71 which is arranged to act on the lever 69 and thereby draw back and release the locking collar 65. The releasing of the locking collar, however, is under the control of means which depends for its operation upon the presence or absence of matrices in the distributing mechanism. Such means in the construction shown comprises a bar 72 which is pivoted at 73 on the upper portion of the channel entrance 17, below the rear upper distributer screw 74, this distributer screw together with the distributer screws 75 operating to convey the matrices M along the distributer bar 11. The bar 72 is connected to a link 76, the

lower end of this link being connected at.

77 to a lever 78. This lever is pivoted or fulcrumed at 79 to one of the upper side brackets 46 and is operatively connected to a rod 80, the lower end of this rod-being connected to an arm 81 of a lever which is pivoted or fulcrumed at 82 to the bracket 62, the other arm 83 of said lever operating in a circumferential groove 84 of the slidable locking collar 65. When the collar 65 is in locked position, as shown in Fig. 1, the bar 72 will occupy its normal position below the conveyer screw 74; and to the rear of the path of the matrices M, and preferably it stands at an incline in order that itmay serve as a guide or guard to insure the proper entrance of the matrices into the chutes 85 which lead to the respective magazine channels. In order to prevent shifting of the magazines not only while matrices are being conveyed to the appropriate magazine channels by the conveyer screws preferably but also while any matrices remain in the distributer box, that end of the bar 72 adjacent to the distributer box 86 has an extension 72 which projects into a position to engage any matrices that may be left in the box but have not been lifted into engagement with the conveyer screws, as shown in Fig. 11-. Shiftingof the magazines is accomplished by rotation of the shaft 61 and before this shaft can be rotated it is necessary to release the locking collar 65. This is accomplished by pushing the handle 61 rearwardly. Such action will be permitted when there are no matrices either on the conveyer screws or in the distributer box. Should, however, any matrices remain either on the conveyer screws or in the distributer box, they will prevent releasing of the look- I menace this collar involves swinging of the bar 72 into the path of the matrices, and the presence of a matrix either on the conveyer screws or in the distributor box will obstruct this movement of the bar 72, and through the connections between the bar 72 and the locking collar 65 the latter will be held in its locked position, thereby preventing shifting of the magazines until all the matrices belonging to the particular magazine in operative position have been distributed thereto. In the construction shown, the matrices each have four lugs, the two upper lugs being engaged by the upper conveyer screws 7d and 75 and the forward lower lug being engaged by the lower conveyer screw 7 5, and the controlling bar 72 is arranged to engage the fourth or lower rear lug on the matrix while the same is on the distributer bar.

In the construction provided by the present invention, the magazine yoke and the magazines and frames carried thereby can be swung bodily to the rear of the machine to permit changing of the magazines. In the construction shown, this operation is effected by manipulation of the shaft 61 which, as stated, serves to shift the magazines. For this purpose the cam 28 is provided with a longitudinally movable bolt 87 and the bracket 13 is provided with an opening 88 which is adapted to receive one end of the bolt 87 when the cam 28 has been rotated into the position shown in Fig. 6 with the magazine yoke in its lowermost position. The cam 28 is also provided at one side with a stop 89 which is arranged to engage a similar stop 90 on the arm 29 attached to the bracket 13 when the cam 28 has been rotated into the position shown in Fig. 6 where the magazine yoke is inits lowermost position. By continuing the operation of the shaft 61 after the magazine yoke has reached the limit of its lowermost position, the stop 89 on the cam 28 is brought into engagement with the stop 90 on the arm 29, and upon further rotation of the cam 28 the bracket 13 will rotate in unison with the cam 28 and will be thereby rocked, tilting the magazines rearwardly about the shaft 3 as an axis. The bolt 87. is arranged to engage in the opening 88 of the bracket 13 in order to prevent the magazines from dropping rearwardly after the center of gravity of the magazines and their mounting has passed the shaft 3. For this purpose the bolt 87 is provided with a pin 91 which operates in a groove 92 formed in a collar 93, the latter being fixed to the shaft 3 so as to occupy a. stationary position. The groove 92 has an offset portion so located that as the magazines are swung to the rear the bolt 87 will be operated to engage in the opening 88, thereby coupling the bracket 13 positively and directly to the cam 28, and as the magazines are swung forwardly toward normal position the bolt 87 will be automatically withdraw by this ofi'set portion of the cam groove 92, thereby uncoupling the bracket 13 from the cam 28 and permitting the latter to operate as hereinbefore described to effect shifting of the magazines. Fig. 3 shows the magazines swung to the rear by the dotted lines, and when the magazines are in this position they may be changed readily.

In order to prevent spilling of the matrices from the magazines when they are swung into position for removal, the upper or distributor end of each magazine is pro vided with a shutter 94? which is adapted to extend across and close the upper or distributer end of the magazine and to be retracted when the respective magazine is in operative position in order to permit the matrices to be distributed into the magazine. In the construction shown, these shutters are provided with relatively long fiat springs 95 which are secured'to the lower end of the magazine, these springs having a normal tendency to swing the shutter into closed position and to retain it in such position and the shutter will therefore operate to prevent spilling of matrices when the magazine is brought into the reverse position for removal, as shown in Fig. 3. Means is provided for antomatically opening the shutter of each magazine as the latter is brought into operative osition and for causing closing movement of such shutter as the respective magazine is moved out of operative position. In the construction shown, a pair of segments 96 are pivoted on each magazine frame at 97, and a pair of cam plates 98 are secured at the inner sides of the distributer bracket arms 2 and 7. Each segment has an end 99 arranged to engage the respective cam plate 98 as the corresponding magazine descends into operative position, the segments for such magazine being thereby tilted and causing their rear ends 100 to act upon and retract the respective shutter 94, thus opening the upper end of the magazine in use and permitting matrices to enter from the distributer. As each magazine is moved out of operative position, its shutter returns to closed position and this occurs not only during shifting of the different magazines into operative position but also when the magazines are swung to the rear and in position for removal. By this constructimi, the handle 6%, which is conveniently located within easy reach of the operator at the front of the machine, serves to release the lock, to raise and lower the magazines and slide them rearwardly or forwardly to shift from one magazine to another, and to rock the magazines rearwardly into a position to permit removal or changing of magazines, and to return the magazines to their normal forward position.
