Andreas Schulze in Cladow, Havel. Verfahren zur Herstellung von Sprengkapseln.Andreas Schulze in Cladow, Havel. Process for the production of detonators.

Zusatz zum Patent 355729.Addendum to patent 355729.

Patentiert im Deutschen Reiche vom 29. April 1924 ab. Längste Dauer: 23. April 1937.Patented in the German Empire on April 29, 1924. Longest duration: April 23, 1937.

In dem Patent 355729 ist ein Verfahren zur Herstellung von Sprengkapseln geschildert worden, bei dem eine Domung des Bodens erfolgt, während der Sprengstoff in der Hülse durch den Preßstempel verdichtet wird.In the patent 355729 there is a method for Manufacture of detonators has been described, with a doming of the soil takes place while the explosive is compressed in the sleeve by the ram.

Durch Versuche ist festgestellt worden, daß bei derartig hergestellten Sprengkapseln sehrExperiments have shown that detonators produced in this way are very

schwer entzündlicher Sprengstoff, z. B. auch phlegmatisierter Sprengstoff, viel leichter zur Explosion gebracht werden kann, wenn man nicht Kupferhülsen für die Sprengkapseln verwendet, sondern Aluminiumhülsen. Solche Aluminiumhülsen haben aber den Nachteil, durch -.,manche Sprengstoffüllungen, z. B.hardly flammable explosives, e.g. B. also phlegmatized explosives, much easier to Explosion can be brought about if one does not use copper sleeves for the detonators, but aluminum sleeves. Such aluminum sleeves have the disadvantage, however, by -., Some explosive fillings, z. B.

Knallquecksilber, möge dies als Gesamtladung oder nur als Initialladung verwendet werden, mit der Zeit „angegriffen und ,zerstört zu werden. Das Wesen der neuen Erfindung besteht darin, daß man als Kapselhülsen beiderseits offene Hülsen verwendet, z. B. aus Kupfer, welches von Knallquecksilber nicht angegriffen wird, und daß das Eindrücken des Bodens oder Dornen auf eine den offenenFumed mercury, may this be used as a total charge or only as an initial charge, over time, “to be attacked and destroyed. The essence of the new invention consists in the fact that capsule shells on both sides open sleeves used, e.g. B. made of copper, which is not attacked by fumed mercury will, and that pressing the soil or thorns on one of the open

ίο Boden abdeckende Bodenklappe erfolgt, die aus Aluminium oder ähnlichem Material besteht, das bezüglich der Zündungsfähigkeit die guten Eigenschaften des Aluminiums aufweist. Die gewöhnlich aus Knallquecksilber bestehende Initialladung kommt hierbei mit der Aluminiumkappe also nicht in Berührung. Ferner ist der Vorteil vorhanden, daß der Bodenteil der Kapsel infolge der Doppelwandung eine Verstärkung aufweist, wodurch bekanntlich'die Wirkung erhöht wird.ίο Floor flap that covers the floor consists of aluminum or a similar material, which with regard to the ignitability has the good properties of aluminum. Usually made of fumed mercury The existing initial charge does not come into contact with the aluminum cap. There is also the advantage that the bottom part of the capsule as a result of the double wall has a reinforcement, which is known to increase the effect.

Die Zeichnung gibt zwei beispielsweise Ausführungsformen der nach dem Verfahren hergestellten Kapseln wieder, und zwar für den Fall, daß lediglich ein Eindrücken, nicht aber ein Durchlochen oder Zerreißen des Bodens stattfindet. Da Aluminium nachgiebiger ist als das gewöhnliche Kupfermaterial, so lassen sich ziemlich tiefe Dornungen herstellen, ohne daß ein Reißen des MaterialsThe drawing gives two example embodiments of the manufactured according to the method Capsules again, in the event that the bottom is only pressed in, but not perforated or torn takes place. Since aluminum is more pliable than the common copper material, so fairly deep thorns can be produced without tearing the material

erfolgt. ·he follows. ·

' In Abb. ι ist α die an beiden Seiten offene Kupferhülse. Auf den Bodenteil wird die Kappe b, aus Aluminium, o. dgl., aufgeschoben, dann der Sprengstoff eingefüllt, und nun erfolgt im Löffel das Verdichten desselben durch den Stempel, wobei die Dornung c durch Relativverschiebung zwischen Kapsel und einem darunter befiadlichen Dorn erfolgt. Die Löffelbohrungen sind der Form dieser zusammengesetzten Kapsel angepaßt. Für Abb. 2 kann man Löffel mit gewöhnlichen zylindrischen Bohrungen verwenden, da' die Kappe b in die Hülse α eingesetzt ist, von deren zylindrischen Wandungen also umschlossen wird.'In Fig. Ι, α is the copper sleeve open on both sides. The cap b, made of aluminum, or the like, is pushed onto the bottom part, then the explosive is filled in, and it is now compressed in the spoon by the punch, the spike c being effected by relative displacement between the capsule and a mandrel located underneath. The spoon bores are adapted to the shape of this composite capsule. For Fig. 2 you can use spoons with ordinary cylindrical bores, since 'the cap b is inserted into the sleeve α , so it is enclosed by its cylindrical walls.
