Description

Drahtschlinge zum Verbinden der Sprengpatrone mit der Zündschnur. Zum Verbinden der Hülle von Sprengpatronen mit der Zünidschnur, zwecks unverrückbarer Lagerung der Zündung in der Sprengmasse, wurde an Stelle von Bindfaden eine Drahtschlinge von Omegaform argegeben und auch versuchsweise in einigen Bergwerken angewandt.Wire loop for connecting the explosive cartridge to the fuse. For connecting the shell of explosive cartridges with the fuse cord, for the purpose of immovable Storage of the ignition in the explosive mass was replaced by a wire loop given by Omegaform and also used on a trial basis in some mines.

Ihre Anwendung hat sich nur bedingt bewährt. Wurden nämlich die Drahtenden beim Verschließen, in der Absicht, die Verbindung recht fest zu machen, stärker angespannt als es die Struktur der Zündschnur verträgt, dann traten Abwürgungen des Zündganges ein und das alte Übel der »Versager« trat wieder in Erscheinung.Their application has only proven itself to a limited extent. Namely, the wire ends were when closing, with the intention of making the connection quite tight, stronger tense than the structure of the fuse can handle, then stalling occurred of the ignition and the old evil of the "failure" reappeared.

Anderseits kommt es häufig vor, daß bei stabiler Zündschnur (Friedensware) durch Überanstrengung des Drahtes die Drahtenden so knapp an der Würgestelle abbrachen, daß nur ein geringer Bruchteil der Drahtenden stehen blieb und die Verbindung so mangelhaft wurde, daß ein geringer Anstoß diesen »Scheinknoten« wieder löste.On the other hand, it often happens that with a stable fuse (peace goods) due to excessive strain on the wire, the wire ends broke off so close to the choke point, that only a small fraction of the wire ends remained and so did the connection What became unsatisfactory was the fact that a slight nudge loosened this "sham knot" again.

Diese Übelstände werden restlos dadurch beseitigt, daß in dem Schlingenkörper eine oder mehrere Dehnungsfalten angebracht werden, die bei Überanstrengung der Drahtschlinge sich ausdehnen und dadurch eine sichtbare Formveränderung ergeben, ohne der Festigkeit des Verschlusses Abbruch zu tun.These inconveniences are completely eliminated in that in the sling body one or more expansion folds are attached to prevent excessive exertion of the Wire loop expand and thus result in a visible change in shape, without damaging the strength of the fastener.

Die Zeichnung stellt den Erfindungsgegenstand dar, und zwar zeigt: Fig. r eine Drahtschleife mit einer Dehnungsfalte, I# ig. a desgleichen mit mehreren Dehnungsfalten und Fig. 3 ein Anwendungsbeispiel.The drawing represents the subject matter of the invention, namely shows: Fig. R a wire loop with an expansion fold, I # ig. a same with several Expansion folds and FIG. 3 shows an example of use.

Solche Dehnungsfalten z und a können bei den mannigfachsten Formen von Drahtschleifen 3 und 4 angebracht werden; es ist nur zu beachten, daß die Dehnungsfalten erprobterweise in ihrem Umfang die drei- bis vierfache Drahtstärke nicht überschreiten.Such expansion folds z and a can be in the most varied of forms be attached by wire loops 3 and 4; it just has to be noted that the stretch folds It has been tried and tested not to exceed three to four times the wire thickness.
