Zweites Zusatz - Patent zu No. 708 vom 6. Juli 1877.Second addition - patent to No. 708 of July 6, 1877.

Patentirt im Deutschen Reiche vom 6. Januar 1882 ab. Längste Dauer: 5. Juli i8g2.Patented in the German Empire on January 6, 1882. Longest duration: July 5th i8g2.

Die Neuerung betrifft den Schutz der Kanten des aus ein- und mehrfachen schraubenartigen Drähten mit Querstäben in den Gelenken bestehenden Metallgeflechtes, welches durch Zusatz-Patent No. 3909 vom 23. Juni 1878 geschützt ist. Dieser Kantenschutz wird bewirkt, i. indem die Querstäbe nicht mit Köpfen versehen, sondern nach beiden Seiten hakenförmig umgebogen werden, Fig. 1, so dafs die Haken der Gelenkstäbe inmitten des Geflechtes zu liegen kommen und so gegen Verschiebung geschützt sind, 2. indem gleichzeitig die Enden der einzelnen Drähte verkürzt und nach einwärts umgebogen werden, so dafs in dieser Verbindung mit den umgebogenen Gelenkstäben das Metallgeflecht eine glatte Drahtkante erhält, welche jegliche andere Schutzeinfassung aus Leder, Gummi etc. überflüssig macht.The innovation concerns the protection of the edges of the single and multiple screw-type Wires with cross bars in the joints existing metal braid, which by additional patent No. 3909 of June 23, 1878. This edge protection is effected i. by not providing the cross bars with heads, but hook-shaped on both sides are bent, Fig. 1, so that the hooks of the joint bars in the middle of the braid to come lying and are thus protected against displacement, 2. by simultaneously opening the ends of the individual wires are shortened and bent inwards, so that in this one In connection with the bent joint rods, the metal mesh is given a smooth wire edge, which makes any other protective edging made of leather, rubber, etc. superfluous.

Statt der einfachen runden Gelenkstäbe können auch zwei halbrunde Stäbe, Fig. 2, verwendet werden, welche ankerförmig, Fig. 3, nach beiden Seiten umgebogen werden.Instead of the simple round joint rods, two semicircular rods, FIG. 2, can also be used are, which anchor-shaped, Fig. 3, are bent on both sides.

Die Anfertigung des Metallgeflechtes statt aus Drähten mit rundem Querschnitt kann aus solchen mit profilirtem Querschnitt nach Fig. 4 a, 4b, 4c und 4d geschehen, je nach dem Verwendungszweck des Geflechtes.The production of the metal mesh instead of wires with a round cross-section can be made from such done with profiled cross-section according to Fig. 4a, 4b, 4c and 4d, depending on the intended use of the braid.

Die Anfertigung des Drahtgeflechtes kann statt aus flachgewundenen Drähten, Fig. 5, aus solchen rund gesponnenen erfolgen, Fig. 6, und zwar in einfacher oder mehrfacher Zusammenstellung mit Querstäben in den Gelenken.The production of the wire mesh can instead of flat-wound wires, Fig. 5, from such round spun, Fig. 6, in a single or multiple compilation with cross bars in the joints.

Die Verbindung der freien Enden dieses Metallgeflechtes kann mittelst zweier oder dreier rund gewundenen Drähte stattfinden, welche mit Ueberemstimmung der Steigungen des Metallgeflechtes schraubenförmig in die stumpf vor einander gestofsenen freien Enden desselben eingedreht werden.The connection of the free ends of this metal mesh can be made by means of two or three round twisted wires take place, which coincide with the gradients of the metal mesh be screwed helically into the butt before butt jointed free ends of the same.

Claims

Patent Claims:

1. The improvement of the edge protection on the under no. 3909 patented metal mesh by bending the transverse resp. Articulated rods of this braid, as well as the ends of the turns of the same, essentially as described.

2. The production of this metal mesh instead of wires with a round cross-section those with a profiled cross-section, as described.

3. The connection of the free ends of this metal mesh by one to three round coiled wires as described.

4. The production of the wire mesh instead of flat-wound wires, Fig. 5, from those which are spun round, Fig. 6, in a single or multiple compilation with cross bars in the joints.

5. The special uses of this metal mesh:

a) as driving belts for hoists, elevators, endless metal cloths and the like;

b) as armored walls in money and bookcases to protect against burglary;

c) as a bulletproof armor for people;

d) as window and door locks in the form of roller shutters and walls;

e) as fireproof stage curtains either alone or in combination with a rough-sealing base made of non-combustible or fire-proof materials;

f) as a means of protection for war and merchant ships against the effects of Torpedoes, if the metal mesh is appropriate as an undersea protective curtain Extension and distance horizontally under the keel of these ships, or vertically on the sides of them is attached;

g) as an elastic armor for warships, adding the metal mesh, multiplied, as a strong armored belt, the walls of the ship enclosed or. as intermediate armor used within the massive armor of warships.
