Abstract

849,962. Gravity switches operated by tilting. MARTINEK, G. Sept. 19, 1958 [Sept.25, 1957], No. 30078/58. Class 38 (5). [Also in Group XXXVIII] A gravity operated switch for a theft alarm (see Group XXXVIII) comprises an earthed support 27 at the upper end of which is mounted a bracket 32, insulated from earth by the insulating bush 35, carrying the pendulum 36. The pendulum consists of a conductive rod 37, passing through an earthed bush 30 and having a weight 38 at its lower end. The suspension of the rod is such as to permit movement of the pendulum in any direction, and may consist of for example a universal joint or a hook 39 freely suspended from an S-shaped element 40 suspended from the bracket 32. In order to regulate the alarm after fixing, the bush 35 is movable in a slot perpendicular to the plane of Fig. 2, and the bush 30 is movable in a slot in the plane of Fig. 2, so that centring of the rod in the hole in bush 30 may be obtained.
