Abstract: 404,546. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., 9, Kingsway, London.-(Mergenthaler Setzmaschinen- Fabrik-Ges.; 25, Chausseestrasse, Berlin.) June 16, 1933, No. 17239. [Class 100 (iii).] Magazines.-A type-bar-making machine is provided with a plurality of magazines movable to bring a selected magazine into operative position and a plurality of magazine entrances rotatable to bring a selected entrance into operative position, the rotation of the entrances being effected by means actuated by and during the movement of the magazines. The magazines 1-3, Fig. 1, are supported on a frame 4, and the magazine 1 has a channelling different from the magazines 2, 3, and is used with the entrance 26, while the magazines 2, 3 use the entrance 27. The frame 4 carries rollers 5, 6 adapted to run on cams 7, 8 which are mounted on shafts 12, 12a, united by sprockets 9, 10 and a chain and operated simultaneously by a hand lever 13 when a change of magazine is desired. The shaft 12 carries a cam 14 formed with three recesses and which acts on a pivoted lover 16 which is connected through a link 18 to a pivoted lever 19, formed with a projection 21 to engage a pin 22 on an arm 23. The arm 23 is pivoted on a fixed stud 24 and together with a similar arm on the other side of the machine carries on trunnions 25 the rotatable entrances 26, 27. On a trunnion 25 is secured a pinion 28 which can be rotated through gears 30, 29 by a rack 34, adjustably and detachably secured to the frame 4. The magazine entrances are provided with locking means for holding them in their adjusted positions, comprising a disc 35, fixed to the trunnion 25, and having notches 36, 37 with which engages a spring-pressed catch 38. The latter is formed with a nose 40 which cooperates with a spring-pressed pawl 41 to effect the release of the disc 35, which is subsequently relocked by the catch 38 through the action of a pin 44 on the pinion 30. In operation, when changing from magazine 1 to magazine 2, the hand lever 13 is operated, whereupon the cam 14 swings the lever 19, through the connecting linkage, against the stud 22 and thus rotates the lever 23 about the stud 24, when the magazine entrances take up the position shown in Fig. 3. The nose 40 of the detent 38 is thereby brought into engagement with the pawl 41 and the detent is accordingly disengaged from the recess 36 in the disc 35. The rack bar 34 then engages the pinion 30 and rotates the entrances so as to bring the entrance 27 uppermost and into operative position in relation to the magazine 2. The pin 44 on the pinion 30 engages the pawl 41 and releases the detent 38 which springs into engagement with the notch 37 of the disc 35. The arms 23, lever 19, and the associated parts finally return to the position shown in Fig. 1, as the roller on the arm 16 drops into the appropriate recess on the cam 14. In changing from magazine 2 to 3, the entrances are displaced as shown in Fig. 3 but are not rotated, and entrance 27 remains in the operative position. The rack-bar 34 may be changed to give any desired movements of the entrances during the movements of the magazines, and the pinions may be replaced by friction gears or chain and sprocket gearing; the entrance changing gear may also be arranged on both sides of the distributor.
