KAISERLICHESIMPERIAL
KLASSE 5: BergbauCLASS 5: Mining
Der Brustschild bildet einen der beiden Haupttheile eines neuen Vortriebsapparates für Stollen in schwimmendem und mildem Gebirge, dessen anderer wesentlicher Theil der sogenannte Schildmantel ist, welcher in der beiliegenden Zeichnung mit den Buchstaben m r bezeichnet ist. Der flüfseiserne Schildmantel umgreift schachtelartig auf kurze Lange die ebenfalls aus Eisen hergestellte Auskleidung T des fertigen Tunnels.The breast shield forms one of the two main parts of a new propulsion apparatus for tunnels in floating and mild mountains, the other essential part of which is the so-called shield jacket, which is indicated in the accompanying drawing by the letters m r. The flux-iron shield jacket encompasses the lining T of the finished tunnel, which is also made of iron, in a box-like manner over a short length.
Der Innenraum des Schildmantels ist durch die beiden luftdichten Abschlufswände g und i, von denen die erstere sich an die Auskleidung des fertigen Tunnels anlehnt, in zwei Luftkammern getrennt. In der vorderen, dem Gebirge zugekehrten Kammer F befindet sich der Brustschild G. The interior of the shield jacket is separated into two air chambers by the two airtight end walls g and i, the former leaning against the lining of the finished tunnel. In the front chamber F facing the mountains there is the breast shield G.
Derselbe ist in dem von dem Schildmantel umschlossenen losen Ringe X eingebaut. Er besteht aus einer Anzahl Zellen, die mit geraden Begrenzungslinien an einander stofsen. Die Eigenthümlichkeit dieses Schildes besteht nun darin, dafs die aus Flufseisenblechen gebildeten .Zellenwandungen aus der eckigen Querschnittsform in eine cylindrische Form übergehen, so dafs diese Zellen in ihrer hinteren Länge Hohlcylinder bilden, .während die zwischen ihnen und dem Ring liegenden Zwickel nach vorn pflugscharartige Flächen zeigen, deren Form geeignet ist, das Einpressen des Schildes in das Gebirge zu erleichtern; hinten sind diese Zwickelra'ume mit ebenen Platten abgedeckt, welche mit den Zellencylindern zur Versteifung des ganzen Brustschildes fest verbunden sind.The same is built into the loose ring X enclosed by the shield jacket. It consists of a number of cells that meet with straight lines. The peculiarity of this shield consists in the fact that the cell walls formed from fluff iron sheets change from the angular cross-sectional shape into a cylindrical shape, so that these cells form hollow cylinders in their rear length, while the gussets lying between them and the ring forward ploughshare-like surfaces show the shape of which is suitable to facilitate the pressing of the shield into the mountains; At the back these interstices are covered with flat plates, which are firmly connected to the cell cylinders to stiffen the entire breast shield.
In jeder Zelle befinden sich eine cylindrische und eine kegelförmige Schraube. Beide sitzen auf einer Welle c, welche einmal in der Querwand i und ferner mittelst des in der Cylinderzelle angebrachten Lagerhalters / gelagert ist.In each cell there is a cylindrical and a conical screw. Both sit on a shaft c, which is mounted once in the transverse wall i and also by means of the bearing holder / mounted in the cylinder cell.
Die mit kurzer, 5/4 fächer Windung versehene cylindrische Schraube ρ füllt den ganzen Querschnitt des Zellencylinders aus. Sie hat einerseits den Zweck, das unzeitige Einstürzen des Gebirges in die Kammer F zu verhindern und dem vor dem Brustschilde anstehenden Gebirge unter allen Umständen einen sicheren Halt zu gewähren; andererseits soll sie dazu dienen, den Boden in bestimmter Menge, dem Vortrieb des Brustschildes in das Gebirge entsprechend, aus dem Brustschilde in die Vorkammer zu befördern.The cylindrical screw ρ with a short, 5 / 4- fold turn fills the entire cross-section of the cell cylinder. On the one hand, it has the purpose of preventing the untimely collapse of the mountains into chamber F and of giving the mountains in front of the breast shield a secure hold under all circumstances; on the other hand, it should serve to transport the soil in a certain amount, corresponding to the propulsion of the breastplate into the mountains, from the breastplate into the antechamber.
Die kegelförmige Schraube s ist auf der Spitze der Welle c angebracht und dazu bestimmt, das Gebirge zu lösen. Um mit derselben nöthigenfalls vorbohren zu können, endigt die Welle c mittelst Kolbens in einer hydraulischen Presse y, durch welche die Vor- und Rückwärtsbewegung der kegelförmigen Schraube s bewirkt werden kann. An dieser Bewegung der Welle nimmt die cylindrische Schraube ρ nicht Theil.The conical screw s is attached to the tip of the shaft c and is intended to loosen the rock. In order to be able to pre-drill with the same if necessary, the shaft c ends by means of a piston in a hydraulic press y, by means of which the forward and backward movement of the conical screw s can be effected. The cylindrical screw ρ does not take part in this movement of the shaft.
Dieselbe ist zu diesem Zweck lose auf der Welle angebracht und wird von derselben mittelst Nuth und Feder mitgedreht.For this purpose it is loosely attached to the shaft and is held by the same Turned by means of a nut and a feather.

The rotating movement is done by the dynamo-electric machines a, which are suitably mounted on the transverse wall q , and of which the. Rotary motion
