Linotype machines.-Relates to change of magazine in single or multiple magazine linotype machines, and consists in providing means for effecting seriatim the operations of locking the escapement levers, disengaging the escapement rods from the escapement levers, and locking the key-levers. Specifications No. 14,582, A.D. 1890, No. 24,605, A.D. 1894, and No. 15,058, A.D. 1904, are referred to. The escapement levers 8, Fig. 1, are locked by a rock-shaft 25 provided with a groove 27 or series of fingers, the escapement rods are disengaged by a rock-shaft 29 provided with a ridged bar or series of fingers, and the key-lever rods are locked by a rock-shaft 33 provided with a face 35 or series of fingers. The three rook-shafts 33, 29, 25 are actuated seriatim by a sliding-bar 36 operated by a handle 39 retained in its two positions by a spring bolt 42. The shaft 33 is actuated by means of a stud 49 and slotted lug 47, the shaft 29 by means of a cranked pin 50 and a slot 51, and the shaft 25 by means of a crank-pin 54 and spring push-piece 52. The shaft 25 is turned to locking position against the action of a spiral spring, which returns the shaft on the reverse movement of the bar 36. The shaft 25 is retained in locking position by means of a detent 56 engaging behind a shoulder 57. Fig. 7 shows an. arrangement of multiple actuators 61 for the crank-pins 54 in a multiple magazine machine. The actuators 61 are carried by a spring-supported bar 60 on the sliding- bar 36, and are normally retracted by springs 65. When it is desired to change a magazine, the corresponding actuator is depressed and then rotated, so that it is held depressed by means of a pin 63 normally located in a slot 64.
