T. Mi. 35 (Stahl): Tellermine—Type 3 (Steel)

T. Mi. 35 (Stahl): Tellermine—Type 3 (Steel) WW2

The design of the third type of Tellermine does not differ greatly from that of the other two models. It is distinguished by the radial flutings on the upper face (a), which extend to the edge of the surface. On the underside of this pressure plate (a) is a flat strengthening ring (b), spot-welded to the plate.

The ring (c) is secured to the body of the mine (d) by a number of punches. This ring retains the pressure plate in position against the spring (b). The rubber seal (i) between the body of the mine and the pressure plate protects the operating mechanism against moisture and dust.

The mine body and the base (f) are similar in construction to the type 1 T. Mi. 35, type 1 having an adapter to take an additional side igniter, which is located diametrically opposite the handle, and type 3 having an adapter for the base igniter. In the case of type 3, the igniter is screwed down until it rests on the rim of the socket (h), and the screw plug (g) is then not required.

The design for the mine appears to be a compromise between the Tellermine No. 1 and the Tellermine No. 2. In the former the whole of the mine cover forms the pressure plate and the mine is known to be subject to blast effects. The smaller area of the pressure plate in Tellermine No. 2 reduced the susceptibility of the mine to blast but at the same time reduced the available area for operating the mine.

T. Mi. 35: Tellermine—Types 1a & 1b

T. Mi. 35: Tellermine Types 1a & 1b

There are two models of the type 1 Teller Land Mine. Both types, which are painted olive drab, consist of a flat, circular bottom plate, a steel dome-shaped body which contains the bursting charge, an aluminum retaining ring into which a rubber sealing ring is assembled, and a cast aluminum top, also slightly dome-shaped. A formed iron wire handle is attached to the side wall by welded steel straps.

The bursting charge is initiated by action of the pressure igniter which is screwed into the well cup in the top of the mine. This igniter is cylindrical in form, 2.3 inches long, and 1.625 inches in diameter. A heavy compression spring, located inside the well, is held in position by a forward lip on the underside of the top of the mine. Two other well cups, one through the sidewall and one through the bottom plate, are provided for use when auxiliary pull-type igniters are assembled. On the body cover, concentric with a brass setting screw, are stamped two arrows, one pointing to the “Scharf” (armed) marking, and the other to the “Sicher” (safe) marking. A red spot .1 inch in diameter on the head of the setting screw is used to aline the setting mechanism with the index marks.

The only difference between type 1a and type 1b is in the loading of the bursting charge. Type 1a contains a 10.55 pound charge of pressed TNT; type 1b contains an 11.41 pound charge of cast TNT and three large PETN booster pellets imbedded in the bursting charge. Each pellet has a cavity into which a detonator well is assembled.
