Abstract

343,806. Frangible links for firecontrol devices. MATHER & PLATT, Ltd. and ROBERTS, A., Park Works, Manchester. April 9, 1930, No. 11263. [Class 47 (ii).] A thermally-responsive link for controlling firedoors and other fire appliances, comprises separable members adapted to be connected to ties, and having parts which tend to move together but are prevented from doing so by a glass or like bulb containing a bursting charge of fluid and held compressively between the parts. As shown, Fig. 1, separable members a, b pivoting on knife-edges f, g have eyes c for connection to ties, for example on the door and a fixed part, and their free ends are held apart by a glass bulb d. In a modification, Fig. 3, the member b comprises arms pivoted together at hand outturned at the ends h<1> to separably engage the member a. In another modification, Fig. 5, the members comprise arms a, a<1> and b, b<1> with interengaging cupped ends. In another modification, Fig. 8, the members a, b have interengaging cups held from separation by the bulb d and a yoke b<2>. In another modification, Fig. 10, one member comprises scissors-like arms b, b<1> having jaws s, t which are held closed, by the bulb d, on a pin r forming part of the member a.
