This inventionrelates to typographical composing machines.

In such machines having a plurality of magazines arranged in superposed relation as a column, it is usual to employ matrix entrance channels (hereinafter called magazine entrances) capable of being interchanged. and which, when the magazines are shifted are changed one for another by axial rotation. Such change-over is effected at the same time as the shifting movement of the magazines, so that the rotation and the change-over of the entrances is performed at every magazine shifting operation. Such means are therefore only applicable to machines wherein a change-over of the magazine entrances is necessary each time the magazines are shifted.

In order to allow application of this automatic rotary change-over of the magazine entrances to a particular magazine arrangement, ithas been proposed, when using a rack bar andpinionmechanism for the rotary change-ovento make the rack bar interchangeable and to fit it to the magazine arrangement in use for the time being. This arrangement makes it necessary however to have different rack bars always available and to interchange them when required.

The object of the invention is to overcome these disadvantages in the known arrangements,

and to make the rotary change-overof the magae zine entrance entirely independent of the magazine change. According to one embodiment of the invention the locking and the change-over of the magazine: entrances, joined together into a rotatable unit, is effected by the movement of a handle, operating the release of the magazine shift, beyond the extent required for releasing the magazines. i

In the drawings, one constructional form of the invention is illustrated by way of example, and in the said drawings:-

Figure l is a diagrammatic side elevation of the relevant parts of a matrix composing and line casting machine according tothe invention;

Figure 2 shows, on a larger scale, the magazine entrances together with the pertinent changeover and locking mechanism in the operative position; V

Figure 3 is a part of Figure 2 and shows the parts after their release, and

Figure 4 is the same illustration as Figure 3, but showing the said parts after the changeover.

In the construction illustrated in the drawings, i is the machine frame, and 2 the magazine column, consisting of any desired number of magazines (four being shown in the construction exemplified) which are supported by a suitable rack bars 3 are articulated to it, and pref erably to the base frame. The rack bars mesh 10 with toothed gears l, upon the shaft. of which are secured bevel gears 5 in mesh with bevel gears 6 mounted on a shaft 1, and the shaft 1 carries a handle 8 so that by turning the handle, the magazines will he adjusted to different levels. When changingover from one magazine to another, it is necessary for the shaft 1 to be turned to a certain extent, (preferably tothe extent of one whole revolution for. changing from one magazine to the next), and in. order tobe able to lock. the shifting frame after each shifting operation, a disc 9 is mounted upon the shaft 7 and carries on its periphery a notch, in which engages a ledge l9 mounted. on a lever 52 adapted to. swing about a stud l i on the magazine frame. Upon a pivot i3 is located a three-armed lever,. one arm i l of which is formed as a handle, the second arm 65 is articulated to a draw-rod l5. and'third arm ll consists of a segmental portion, which is adapted to bear against a roller 50 i8 mounted on the lever l2. The lever i2 is also provided with a cam is serving to move a lever 29, fitted with a roller, which is loosely mounted on the shaft l3 and serves to rock the releasing rods 2| which operate the release of the matrices from the magazine, but which must be moved away from the magazines before the latter are shifted. When therefore the lever I4 is swung clockwise, i. e., when it is raised, the segment I! bears against the roller 28 and swings the lever 40 12, moving the ledge iii out of the slot of the disc 9 and thereby release. the shaft 1. At the same time the cam 59 acts against the: lever 25 and swings the matrix releasing rods 2i away from the magazine, so that the shifting of the magazine can proceed.

According 'to the invention, further rocking movement of the said handle I l causes the release and the rotary change over of the magazine entrances,v and as shown this is effected by means of the rod l6 attached to the lever arm 15. This rod i5 is linked by means of a stud 22 to a double lever 23 Which'is adapted to rock about the pivot 24 located on the lever 25, the lever 25 being itself capable of swinging about a pivot 26. On the lever 25 are two abutment screws 2?, 28, which limit the rocking movement of the lever 23 about its pivot 24.

Upon the shaft 26 is also mounted a toothed wheel 29 which is in mesh with a toothed wheel (ill, fast on the shaft 3| upon which is also firmly secured the support 32 for the two magazine entrances 33, 34. The shaft 3| is located. on a swinging arm 35 which is adapted to rock about a stationary stud 36 on the machine frame. On the same arm 35 is also located the stud 26, and a further pivot stud 3'! for a double lever at one end of which is attached a spring 38 whereas the other end carries a pin 39. The latter, under the action of the spring 38 is capable of entering a recess 40 in a disc 4| positively secured upon the shaft 26. A detent also adapted to engage in the recess 40, is pivotally mounted upon a shaft 24 and by a spring, not shown in the drawings, is pressed against the disc 4|. A stud 42 is also provided on the machine frame to come into contact with an abutment 43 on the arm 35 in order to limit the swinging movement of the arm 35 about the stud 36.

The mode of operation of the present arrangement is as follows:-

When the operator desires to shift the magazines he first swings the handle I 4 in order to release the shifting mechanism. When the lever I4 is raised to a certain extent the shifting shaft l, as previously mentioned is released and the escapement rods 2| moved away from the magazine. Simultaneously, however, and by reason of the pull exerted by the rod It, the arm 35, which is held in its operative position by a very light spring 44, is rocked until the abutment 43 comes into contact with the pin 42. When the parts are in the said position, the shifting of the magazines can be effected in the usual manner without adjusting the magazine entrances. If it is necessary to change-over the magazine entrances, the operator swings the lever I4 clockwise a little further. The pull exerted by the rod l6 rocks the lever 23 about its pivot 24. A rotation of the lever 25 about its pivot 26 does not occur because, in consequence of the engagement of the locking pawl 45 with one of the grooves 49, it is engaged with the disc 4| and the latter is locked against rotation by the pin 39. When, however, the lever 23 is rocked, the free arm of the lever bears against the pin 39 and raises the latter out of its locking position. The parts then occupy the position shown in Figure 3 in which the disc 4| has been released so that any further movement will cause the locking pawl 45 and the disc 4|, together with the shaft 25 and the toothed Wheel 29 mounted thereon, to turn. After a quarter of a revolution, the stud 39, under the action of the spring 38, drops into the nex notch 49 of the disc 4|; the parts are then in the position shown in Figure 4. The transmission ratio between the toothed wheel 29 and the toothed wheel 30 is such that one quarter of a revolution of toothed wheel 29 causes toothed Wheel 39 to make half a revolution and thereby turn the support of the magazine entrance 180 degrees. In place of the magazine entrance 33, which in Figures 2 and 3 is in the operative position, the magazine entrance 34 is brought in operative position by the movement described above.

When, after shifting the magazines, the handle I4 is released, the rod l6 returns to its original position, the shaft 1 is again locked and the releasing rods return into their operative position, enabling the compositor to proceed with his work.

It should be understood that the principle underlying the invention consists in arranging means common for the operations of shifting the magazines and of changing-over the magazine entrances, so that these operations can be carried out independently and in particular so that the magazines can be shifted without necessarily changing the magazine entrances. Within the terms of this principle various modifications of the form of the invention described above may be introduced in order to meet different conditions and requirements which have to be fulfilled, without departing in any way from the scope of the invention.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:-
