Brooklyn, N. Y., a company of New York Application June 24, 1933, Serial No. 677,431

In Germany 10 Claims.

This invention relates to typographical composing and distributing machines of the kind known commercially under the registered trade .mark Linotype, and more particularly to machines of this kind having a plurality of magazines adjustable to bring a selected magazine into operative position, and a plurality of magazine entrances, from which matrices are delivered to .the magazines, and which are rotatably mounted to enable a selected entrance to be brought into operative relationship with the appropriate magazme.

The object of the present invention is to provide improved means for automatically effecting change of the magazine entrances in accordance with the change of the magazines, said improved means being actuated by the movement of the magazines, and being readily adaptable for ef- -fecting any desired change of the magazine entrances to suit varying arrangements of the mag-- azines.

The drawings illustrate, by way of example, one constructional form of the invention, and in the said drawings:

Figure 1 is a side elevation of the top portion of a magazine column with a distributing mechanism according to the invention;

Figures 2, 3 and 4 are side elevations, on an en- .larged scale, of the magazine entrance adjusting mechanism, the adjacent main frame being omitted and the mechanism being represented in different positions in the respective figures, and

Figure 5 is a front elevation as viewed from the left hand side of Figure 2.

-In the arrangement illustrated three magazines 1, 2, 3 are provided, of which the uppermost has a channelling different from that of the other two. The magazines are arranged columnwise .and supported on a frame 4 which is provided with rollers 5, 6 adapted to run on cams 7, 8. The shafts, 12 12 to which the cams are fast carry also sprocket wheels 9, 10, connected by a chain 11, and to the shaft 12 there is secured a hand lever 13, by the rocking of which the shafts and cams are turned, through the just-described connections, thus raising and lowering the magazine column. Upon the shaft 12 is mounted another cam 14 which is formed with a series of recesses; in the constructional example illustrated, three such recesses are provided corresponding in number with the magazines on the machine. The cam 14 acts on a roller 15 on one arm of a lever 16 which is pivoted to the machine frame at 1'7, and has its other arm connected to one end of a 'link 18. The other end of the link 18 is attached July 13, 1932 to a lever 19 pivoted on a stud 20 fixed in the machine frame. This lever 19 has a projection 21 bearing against a pin 22 on an arm 23 pivotally mounted on a fixed stud 24. A similar arm 23 is provided at the opposite side of the machine frame, and the two arms 23 pivotally support the magazine entrances 26, 2'? by means of trunnions 25 journalled in the free ends of the said arms. The two magazine entrances 26, 27, are arranged in inverted relationship, back to back. Upon the trunnion 25 represented in the drawings, is secured a pinion 28, and a pinion 23 is adapted to turn on the respective stud 24, these two pinions being geared with each other by means of a pinion rotatable on the respective arm 23.

To the magazine supporting frame 4 is secured a bracket 31, the form of which can be seen best. in Figure 4. The connection of this bracket to the frame is effected by two screws 32 and 33 passing through slots in the bracket so that the latter can be adjusted relatively to the frame 4. The bracket 31 carries on a projection a rack bar- 34. The teeth of the rack bar are adapted to engage the pinion 29 when the bracket 31 is in the position shown in the drawings. By loosening the screws 32, 33 and moving the bracket 31 downwardly relatively to the frame 4, as permitted by the longitudinal slots in the bracket, the rack bar 34 may be adjusted to a position in which it cannot come into engagement with the pinion 29.

Mechanism for locking the magazine entrancesin their terminal positions is illustrated in Figures 2, 3 and 4, and will now be described. Upon the trunnion member 25 is fitted a disc 35 provided with two recesses 36 and 37. A catch or detent 38, adapted to be moved by a spring 39 into oneor other of these recesses, is mounted to rock about the stud 24. A nose 40 is connected to or formed integral with the detent 33, for cooperation with a locking pawl 41 pivotally mounted on a stud 42 on the machine frame, said pawl being held by a compression spring 43 against a stoppin 41 in the position shown in Figures 2 to 4. The pawl 41 has a shoulder upon which the nose b 40 of the detent 38 is adapted to rest, as shown in Figure 3, and an upwardly directed projection provided with an inclined surface, adapted to engage a pin 44 provided on the pinion 30.

The mode of operation of the device is as follows: In the positions illustrated in Figures 1 and 2 the topmost magazine 1 is in operative position; the magazine entrance 25 is in operative relationship with the magazine 1 whilst the magazine entrance 2'7 is out of action, and the detent 119 which they have been turned. As soon as the 38 is engaged with the recess 36 of the disc 35 to lock the entrance 26 in the operative position.

If the magazine column is now shifted by the movement of the hand lever 13 (Figure 1) to bring into operative position the magazine 2, which is intended to cooperate with the entrance 27, the roller 15 will first be forced out of the recess of the cam disc 14 in which it is located, thus swinging the lever 16 clockwise and through the link 18, swinging also the lever 19 about its pivot stud 20. The projection 21 on the lever 19 will thus come into engagement with the stud 22 on the arm 23 and the latter will be swung clockwise about the stud 24. The magazine entrances will thus be moved from the operative position in which they are represented in Figure 2 to the position shown in Figure 3. The nose 40 of the detent 38, during this movement, is brought into engagement with the shoulder of the pawl 41, which prevents the detent 38 from following the complete swinging movement of the entrances, and disengages it from the recess 36 in the locking disc 35.

The rotation of the entrances is effected when the magazine column is moved upwardly, by the rack bar 34 and pinions 29, 30 and 28, the gearing being arranged so that the trunnion 25 is turned half a revolution during the movement of the magazine column for effecting an operative interchange between the two magazines 1 and 2. The magazine entrances will thus be inverted to bring the entrance 2'7 uppermost, the arm 23 for the time being remaining in the position in which it is shown in Figure 3. During the turning of the pinions just referred to, the pin 44 comes into engagement with the inclined projection of the pawl 41 and disengages the said pawl from the nose 40 of the detent 38 which thereupon drops into the groove 37, under the action of the spring 39, and locks the entrances in the position to shifting movement of the magazine column has been completed, the roller 15 drops into the next recess of the cam 14 and. consequently the levers 16, 18, 19 will again return into the starting position shown in Figure 1 and the parts take up the position shown in Figure 4 in which the magazine 2 is in the operative position and in operative relationship with the entrance 27.

If it is desired to bring the third magazine 3 into use, a further turning movement will be imparted to the cams and shafts by the lever 13. In this case, however, the lever mechanism 16, 18, 19 merely swings the arms 23 carrying the magazine entrances, into the position shown in Figure 'if it is desired to change the entrances when changing from the second to the third magazine but not when changing from the first to the secong magazine, it is merely necessary to attach to the frame 4 a bracket 31 having its rack bar 34 appropriately positioned. It is also possible to employ a bracket 31 having a plurality of rack bars for the purpose of effecting more than one change of entrances during the upward or down ward movement of the magazine column. It will be understood, with reference to the arrangement illustrated in the drawings, that when changing magazines by a downward movement of the magazine column, the changing of the magazine entrances will only take place when changing from magazine 2 to magazine 1. 1

The constructional form of the invention above described and illustrated in the drawings is taken as a convenient example, and it will be recognized that modifications of the said constructional form may be made without departing from the invention; for instance, friction gears or chain and sprocket gearing could be substituted for the pinions.

The magazine entrance changing gear may be located on only one side of the distributor but it is also possible to arrange it on both sides thereof and to provide appropriate driving mechanism therefor.
