Application filed March 18, 1915. Serial No. 15,317.

To all whom it may concern Be it known that I, CARL MUEI-ILEISEN, a

citizen of the United States of America, residing at Chausseestrasse 23, Berlin, N. 4:, in the Empireof Germany,have invented new and useful Improvements in Typographical Composing-Machines, of which the following is a specification.

This .invention relates to typographical composing machines such as those known commercially under the trade mark Linotype, and particularly to those which are provided with a plurality of superposed inclined magazines from which matrices are discharged into a single assembler entrance. Hitherto it has been customary to construct such magazines with their delivery ends in substantially the same inclined plane, and either to mount them on the machine so that any desired one of the plurality can be moved into operative relationship with a fixed assembler entrance or to have the magazines fixed and the assembler entrance adjustable at will to cooperate with one or other of them. The last-mentioned arrangement, while possessing certain advantages as compared with that in which the magazines are movable,.has not proved entirely satisfactory for the reason that the adjustment of the assembler entrance has involved an undesirable lack of uniformity in respect of the length of the path of the matrices between the delivery ends of the magazines and the assembler belt, in the several operative positions of the said entrance.

According to the present invention the just-named disadvantage is eliminated by so arranging the magazines in the machine that their delivery ends,instead of, as heretofore, lying in an inclined plane, lie in an imaginary surface forming, or approximately forming, part of a cylinder, hereinafter for convenience referred to as a cylindrical surface, and the assembler plate is pivoted to swing thereunder, so that the distance to be traveledby the matrices is substantially the same for every operative position of the said plate.

The accompanying drawings show two constructional forms of the invention each applied, as a convenient example, to a machine having four magazines.

In these drawings, throughout the several figures of which like reference numerals are used to indicate like or corresponding parts,

Figure 1 is a right-hand side elevation of one of the said constructional forms, only the pertinent parts of the machine being represented; Fig. 2 is a front elevation of the same, some of the parts shown in Fig. 1 being omitted; Fig. 3 is a view similar to Fig. 1 of another constructional form of the invention; Fig. 4, a front elevation thereof, and Fig. 5 a sectional view of the connection between the stationary and movable parts of the assembler plate.

Referring to Figs. 1 and 2, the four superposed magazines 1, 2, 8, 4 are, as is usual, provided with respective escapements 5, 6, 7 and 8, but, as distinguished from the arrangements hitherto generally employed, the said magazines have their delivery ends lying in a cylindrical surface, as indicated by the dotted line 9. The escapements 5, 6, 7 and 8 are operated to release matrices from the respective magazine by one and the same set ofescapement rods 10, cooperating, in the manner hereinafter described, with rods 11, which latter are in turn actuatedby the ordinary cam-carriage mechanism (not shown in the drawings), controlled from the keyboard 12. The released matrices fall from the respective magazine directly into the assembler plate 13 on to the assembler belt 14, and are conveyed by the latter to the star wheel 15 (Fig. 2) by which they are successively added to the assembling line.

According to the present invention, the assembler plate 13 is rigidly secured to a frame 16 pivotally mounted on a rod 17 which, as shown in Fig. 2, is supported in suitable bearings in the machine frame, and which is concentric with the curve of the cylindrical surface 9. The pulleys 18, 19, for the assembler belt 1 1 are mounted in bearings in the frame 16 so that the said assembler plate 13, belt 14 and pulleys 18, 19, move together with the frame 16 when the latter is swung on the rod 17, while the housing 20, in which the star wheel 15 rotates, remains stationary, the entrance to the said housing 20 being funnel-shaped, as shown in Fig. 1, to insure the proper passage thereinto of the matrices delivered from the assembler belt. The assembler belt 14: may be driven by a belt 21, passing over a pulley 22 fast to the spindle of the pulley 19, and suitably guided over intervening jockey pulleys 23 which, although not so shown in the drawings, may be co-aXial with the rod 17, so that the tension of the belt 21 may be maintained throughout the pivotal movement of the frame 16; the belt 21 passes from the guide pulleys 23 to a pulley on the driving shaft. As an alternative to the just described arrangement, the assembler belt 1 can be driven directly from the pulley 18, instead of from the pulley 19. The star wheel 15 is independently driven by means of the pulley'2t, or in any other convenient manner.

The adjustment of the assembler plate 13 into operative relationship with one or other of the magazines, is effected by a handle 25 on a rod 26, which extends through, and is longitudinally movable in, a guide 27 fast to or integral with the frame 16. The rod 26 is provided with a projecting pin 28, which is adapted to engage notches 29 in a plate Or sector 30 fast to the machine frame, for the purpose of holding the assembler plate 13 in any of the operative positions to which it may be adjusted, the pin 28 being retained in any of the notches 29 by a tension spring 31, which acts on a lever arm 32 fast at one end to a rocking shaft 33 and connected at its opposite end, by a link 34, to the rear end of the rod 26.

As stated above, there is only one set of escapement rods 10 for operating the escapements of all the magazines. These escapement rods 10 are brought into operative relationship with the escapements of any one of the magazines simultaneously with the adjustment of the assembler plate 13 to coiiperate with that magazine, and the means by which this is effected will now be described.

Fast to the upper end of the frame 16,

which constitutes a comb which serves to guide the upper ends of the escapement rods .10, each ,of which rods has a slot 36, traversed by a wire or rod 35 extending preferably throughout the whole bank of such rods and fast to the bracket 35, to permit comb plate 40 serving to guide the said lower ends. The plate 40 extends in front of the whole bank of escapement rods, and is fast at one end to the lever arm 32 and at the opposite end to a similar arm fast to is pulled forward preparatory to efiecting an adjustment of the assembler plate 13, the plate 4:0 is also pulled forward, by the consequent movement of the rod 26, link 34:, lever arm 32 and rocking shaft 33, and the respective notches 37 then in engagement with the rods 11 are pulled out of such engagement. The movement of the handle 25 up or down swings the frame 16 on the rod 17, and with it the bracket 35, the shortening or lengthening of that part of the escapement rods 10 between the bracket 35 and plate 40 being permitted by the arcual slots 38 sliding over the rod 39. After the assembler plate 13 has been moved into register with the desired magazine, the notches 37 appropriate to that magazine will be in position to engage the rods 11, and the release of the handle 25 will permit the spring or springs 31 to effect such engagement, as well as to pull the pin 28 into the appropriate notch 29 so as to lock all the parts in the adjusted position. Thus, when the assembler plate 13 is adjusted to cotiperate with the magazine 4:, as indicated in dotand-dash lines in Fig. 1, the pin 28 will be engaging the highest notch 29, and the highest rank of notches 37 will be in engagement with the heads of the rods 11.

The constructional form of the invention illustrated in Figs. 3, 4t and 5 differs from that just described mainly in respect of the fact that the assembler plate 13 is pivoted eccentrically to the cylindrical surface 9 and is movable vertically, or upwardly and downwardly, as well as pivotally, which additional movement enables the radius of the aforesaid cylindrical surface 9 to be less than the distance between the pivotal axis of the assembler plate and the discharging ends of the magazines. This form of construction has the advantage that at the central magazines the distance to be traveled by the matrices is made somewhat longer than at the outer magazines. lVhen cooperating with the magazines 1 and t, the assembler plate 13 is in a more oblique position than when cooperating with the magazines 2 and 3, and consequently the matrices falling from the magazines 1 and 1 are subjected, when passing through the assembler plate 13, to a greater amount of friction than are those falling from the magazines 2, 3, the result being that the period occupied by such passage would differ in respect of the several magazines, but uniformity in this respect is secured by the longer distance which, as aforesaid, the matrices have to travel when falling from the magazines 2, 3.

For the purpose of permitting the abovementioned vertical movement of the assembler plate 13 the frame 16 is provided at its lower end with two slotted bearings 4-1 engaging with a stationary rod 42 on which it pivots, and is connected, by means of a link 48 beneath each of these bearings, to one arm 44- of a three-armed lever (hereinafter, when referred to as a whole, identified by the reference 4 1), fast to a rock shaft 45, the opposite arm 46 of which lever is connected with a spring 17 constantly tending to keep the bottom of the slotted bearings 41 in engagement with the rod 12. The upper end of the assembler plate 13 is retained in operative position, against foreand-aft movement, by the engagement of a pin 18, fast to the frame 16, with one of a number of notches 419 provided in the lower edge of a forwardly extending arm 50 fast to the machine frame.

A handle 51 is fast to the frame 16, and pivoted to this handle at 52 there is a bellcrank lever 53, one arm of which is arranged conveniently for gripping with the handle 51, the other arm being pivotally connected by a link 5 1 to the rod 42, so that when the handle 51 and bell-crank lever 53 are gripped together, the assembler plate 13 is pressed downward, against the above-described action of the spring 17, until the tops of the slotted bearings 41 are in engagement with the rod 42. This movement also servesto disengage the pin 48 from the notch 49 appropriate to the magazine with which the assembler plate 13 is then cooperating, and the latter is then free to be swung, by the handle 51, into position to coeperate with another magazine, after which swinging the release of the grip between the handle 51 and lever 53 will enable the spring 17 to raise the assembler plate 13 into its new operative position, wherein it will be locked by the engagement of the pin 418 with the respective notch 419.

The escapement rods 10 are, in this constructional form of the invention, moved with the assembler plate 13 in a manner somewhat similar to that described in connection with Figs. 1 and 2, excepting that in the present case a longitudinal adjustment of the said rods is necessitated by the shorter radius of the surface 9. In order to provide for this longitudinal adjustment, the bracket of the first described arrangement, in the present arrangement takes the form of a practically flat comb plate 55, and instead of being in rigid connection with the assembler plate 13, it is secured to a lever arm 56, one end of which is pivoted at 57 to a bracket 58 fast to or integral with the frame 16, and the other end of which, by an antifriction roller 59, bears upon the upper edge 60 of the before-mentioned arm 50. This upper edge 60, being stepped, forms virtually a cam track for the roller 59 which is kept in contact therewith by gravity during the pivotal movement of the assembler plate 13. As a result of this construction, when the assembler plate is moved, the escapement rods 10 will, due to engagement lation to the escapeinents of the magazine beneath which the assembler plate is brought. The lower ends of the escapement rods 10 cooperate with the'rods 11 in same manner as in the previously described constructional form, the comb plate 40 being secured to the upstanding arms 61 of the levers 4 1, the disengagement of the notches 37 from the rods 11 being effected by the movement of those arms (31 when the levers 44: are rocked by the gripping together, as before described, of the handle '51 and lever 53. Simultaneously with this disengagement the assembler plate 13 is lowered, and with it the bracket 58, leaving the escapementrods and connected parts for the time being supported on the roller 59. The arrangement of the cam track 60 is such that at the com mencement of the pivotal movement of the assembler plate 13, the escapement rods 10 are lowered away from the escapements with which they had been coiiperating, and

when the assembler plate has reached a position to receive matrices from another magazine, the said rods 10 are raised into operative relationship with the escapements of that magazine. As previously stated, the release of the grip between the handle 51 and lever 53 will effect the locking of the assembler plate 13, and, as will now be understood, the engagement of the appropriate notches 37 with the rods 11 will be simultaneously effected by the rocking of the levers 4st under the influence of the springs 17.

To insure the proper delivery of matrices from the assembler belt to the star wheel 15, the before-described housing 20, instead of being funnel-shaped as in the previously described constructional form, has hinged to its upper end a mouth 20' see Fig. 5-into the upper end of which is telescopically fitted the lower end of the assembler plate 18, so that effective connection between the said assembler plate and the housing 20 is maintained throughout the different movements of the assembler plate relatively to that housing.

It is to be understood that, although the drawings illustrate only one frame 50, one lever arm 56 and one bracket 58, these devices may be in duplicate, the two sets being at respectively opposite sides of the machine.

The foregoing embodiments of my invention have been selected merely by way of example and as preferred forms, but it will be readily understood that there may be other embodiments or adaptations of my invention without departure from its spirit.
