Abstract

250,647. Siemens & Halske Akt.- Ges., and D÷ring, F. Jan. 10, 1925. Automatic exchange selectors.-The armature i of the stepping magnet carries on the same axis g of the driving pawl k<1> and the locking pawl k<2>. A bent spring f engages U-shaped bearings in the pawls and tends to press them together, this movement being limited by a stop l on the pawl k<2>. During the forward and return movements of the armature i, the driving and locking pawls respectively are held in engagement with the ratchet-wheel by inertia. The stroke of the driving-pawl k<1> is limited by a stop a.
