Addendum to patent 352810.

Patented in the German Empire on April 19, 1921. Longest duration: March 10, 1934.

In patent 352810 is a magnet system for Telegraphone described with coil bobbins, which opposed by resilient hinges the spring action are connected to each other so that they can be folded apart somewhat. The present The invention relates to a further embodiment of such a magnet system. While In the main patent, the coil carriers can only be folded apart by a small amount are arranged, they are at the

Magnet system according to the present invention completely foldable. For this purpose, the coils, in the core surfaces of which two iron cores face each other on the same axis or laterally offset from one another, are on each side of the wire in a common carrier, e.g. B. a body made of hard rubber, fiber or metal, attached, best poured. Here, the two coil carriers are connected to one another on the underside by a resilient hinge so that they can unfold against the spring action. In the collapsed, closed state, the end faces of the coils, between which the wire to be inserted runs, touch each other, with a fine groove in them for the passage of the wire, while the ends of the cores protrude slightly beyond the plane of contact so that the Wire must be inserted into the cutouts or slots at the ends of these cores. In order to give the wire a further guide and ^{to facilitate the insertion of the same in the unfolded a} 5 state, one of the bobbins engages with projections on both sides of the bobbins in corresponding recesses or bores in the other bobbin. The projections have slots that are milled through to the contact plane of the coils. When the magnet system is in the opened state, the wire is inserted into the slots in these projections of one of the bobbins. If you then let the magnet system close, it automatically leads into the opposite slots of the second bobbin, whereby its exact position in relation to the magnet coils and magnet cores as well as sufficient guidance in the coil system 4 "is ensured even at high speeds of the wire.

In the drawing, the new magnet system is in play wise embodiment shown, namely Fig. ι shows a vertical longitudinal section through the system, Fig. 2 a plan view in the unfolded state, Fig. 3 a cross section and Fig. 4 a Side view in the unfolded state of the coil carrier.

There are χ and 2 the coil carriers, which can be made of hard rubber, fiber, metal or the like. The magnetic coils 3, 3 ', 4, 4' are expediently cast into these. Their cores 5, 5 'and 6, 6', the ends of which protrude slightly beyond the touching end faces of the coils and have slots for guiding the wire 7, are pushed inwards by springs 8, which are attached to the coil carrier 1 and 2, respectively pressed. Slots for guiding the wire 7 are arranged in the touching end faces of the coils 3 ', 3, 4, 4'. So that the wire can now be easily inserted when the coil carriers 1 and 2 are fully opened (see Fig. 2), the end faces of the coil carriers 1 and 2 are not flat, but have different interlocking projections or depressions. The projections are provided with slots which extend through to the contact planes of the coil surfaces and into which the wire is first inserted into the one coil carrier in the unfolded state. Is allowed to fold up the coil support, then the wire of the other coil carrier automatically sets a ¹ into the corresponding ⁷ S speaking wells. As can be seen from Fig. 1, 9 are arranged laterally to the coils in front of jumps of one coil carrier, 10 are a central projection between the coils of the second coil carrier, 9 'and 10' are the corresponding recesses for these projections. The projections 9 and 10 have continuous slots which extend as far as the plane of contact of the coils, and into which the wire can easily be inserted from above into the one coil carrier after opening it.

The coil carriers are connected to each other by © in hinge ir, which is below the Under the action of a spring 12 it collapses automatically.
