United States Patent G MATRIX-SETTING AND LINE CASTING MACHINES Germany, assignor to Linotype G.m.b.H., Berlin-Templehof, Germany, a German body corporate Application July 16, 1956, Serial No. 597,930 5 Claims. (Cl. 199-18) According to the invention this drawback is overcome a in a simple manner as a result of the fact that a selected combination of holes in the perforated strip, intended for stoppage, actuates, via the scanning device, a lock which interrupts the automatic matrix escapement, and that a member such as a manual key, which can be actuated at will, is provided for re-starting this automatic matrix escapement.

The mechanism is preferably so constructed that, simultaneously with the stopping of the automatic matrix escapement, an optical and/or acoustic signal is actuated, for example a coloured light shines, a bell rings, or a buzzer sounds, and this signal ceases as soon as the automatic matrix escapement is set in operation again. It is also a great advantage to construct the device in such a manner that the member intended for re-starting the automatic matrix escapement at will for example a manual key, can also be used for interrupting the automatic matrix escapement at will.

The device of the invention further makes it possible, in a simple manner, to hold a finished line of matrices in the assembler elevator as a result of which the operator is able to cast this line of matrices repeatedly as desired. For this purpose the combination of holes in the strip, intended for stopping according to the invention, is used instead of the so-called releasing control.

Further features can be seen from the accompanying diagrammatic illustration by way of example, of an arrangement of the co-operating parts of the automatic matrix-escapement mechanism and from the following description.

When the predetermined combination of holes for example 1, in the perforated strip 2, serving for the interruption of the automatic matrix escapement, comes in front of the feeler pin, which is not illustrated, of the feed and scanning mechanism 3, the key rails 4, are displaced in known manner so that, also in known manner, the switch rod 11, via the members 5, 6, 7, 8 and 9, taking with them the manual key 10 provided for stopping at will, actuates the double-pole quick-break switch 12.

As a result, the circuits 13, 14 and 15 fed from the source of current 16, are closed. Through the closing of the circuit 13, the stop magnet 17 is energised and attracts its armature 18, and the axial dog clutch 20 is thus opened that is, disengaged, via the double ar-med lever 19. The result of this is that the worm 22, driven via the pulley 21, turns the wormwheel 23 idly, so that the feed and scanning mechanism 3 is no longer driven, and the automatic matrix escapement is interrupted.

Simultaneously with this interruption, the acoustic sigice nalling system 24 and the optical signalling system 25 are caused to respond due to the closing of the circuits 14 and 15. The special matrices can now be inserted in the line of matrices, for example by hand,

In order to set the automatic matrix escapement in motion again afterwards, the double-pole quick-break switch 12 is again actuated via the members 8, 9 and 11, by pressure on the key 10, and so the circuits 13, 14 and 15 become dead. Accordingly the armature 18 of the magnet 17 drops so that the double-armed lever again engages the axial dog clutch 20, and the drive from the pulley 21 again drives the feed and scanning mechanism 3 via the worm system 22/23. At the same time the signals 24 and 25 are switched 01f.

If the automatic matrix escapement is to be stopped independently of the perforated strip, the double-pole quickbreak switch is actuated by pressure on the manual key 10, via the members 8, 9 and 11, so that the circuits 13, 14 and 15 are connected in exactly the same manner as with the automatic actuation,- the signal systems are caused to respond, and the feed and scanner device is stopped.
