Abstract

921,337. Military entanglements. G. SIEFFERT. June 15, 1961 [June 17, 1960], No. 21671/61. Class 20 (1). [Also in Groups I and XXII] A coil of plain or barbed wire comprises coaxial inner and outer networks 2, 1, each consisting of one or a plurality of wires wound as a helix, the inner network having a smaller number of turns per unit length than the outer and means, e.g. wires 3, for attaching the inner to the outer network. In another embodiment some of the coils of the inner network are elongated outwardly so as to be substantially tangential to the outer network at certain points of its periphery at which points it is stapled to the outer network. In addition successive turns of both the inner and outer networks may be stapled together at points which constitute the vertices of a regular pentagon. In a further embodiment the inner network has every third turn of the coil closed on itself by stapling to form a free turn which is elongated in order to be tangential at two diametrically opposite points to the outer network at which points it is stapled to the latter.
