PERFORATOR MECHANISM FOR PREPARING THE COMPOSING-STRIP OF TYPE SETTING AND CASTING MACHINES.

It is obvious that the switch may be moved by some other part of this system of rods and levers. Thus it may be on the rocking shaft 1.

Our improvement in the arrangement of the magnets in machines of this kind, whether they be for controlling the perforator, the

justifier, or the matrix-selecting mechanism, is illustrated in Figs. 2, 3, and 4. In order to retain the efficient horseshoe magnet, while saving the room occupied by two bobbins, the magnet is constructed with two cores, only one of which is wound, the other being attached to the same anchor-plate as the wound core, so that it is in the same magnetic circuit. At the same time this bare core forms the support for the armature-lever, which is also of magnetically-susceptible material.

In Fig. 2, g and g are the soft-iron cores, g the anchor-plate, and g the bobbin of fine wire. The soft-iron armature-lever '2; is pivoted to the bare core g, so that a short and well-closed magnetic circuit is obtained. Since the core can be brought very close to the bobbin 9 the fulcrum of the lever 01 can be close to the armature, leaving a long arm with a considerable striking distance to lift the stop or perforator o of the particular part of the machine which the magnet is operating and also allowing the armature to be very close to the core 9. The spring '0 is attached to a pin '0 in the anchor plate 9 The latter is rounded at the inner end, as shown in Fig. 4:, and several of them are placed as radii of a circle or are of a circle on the magnet-stand h. The wires from each magnet are brought down through a hole in the stand, lined with insulating material it, to a central terminal plate 7L Having thus described the nature of this invention and the best means we know of carrying the same into practical effect, we claim 1. In a perforator mechanism for preparing the composing-strip of atype setting and casting machine in which a composing type-writer is used for closing the magnetic circuit of a perforator, the combination with the key that releases the counting mechanism of such typewriter to permit it to return to zero, of an electrical switch which closes a magnetic circuit of the perforator when the said key is depressed, in such manner that the circuit is closed and the counting mechanism released by one movement of the operator, substantially as described.

4. In a perforator mechanismfor preparing the composing-strip of a type setting and casting machine, in which the movements of parts are controlled by electromagnets, the combination with punches or stops, of electromagnets each having two cores on the same anchor-plate only one of which cores is wound to permit the magnet to be energized while the other forms the fulcrum of the armature lever, the said anchor-plate being rounded at its interior end and a number of such plates being arranged as radii of a circular arc, substantially as described.
