Abstract

409,569. Frangible struts for fire apparatus. HODGMAN, W. K., 35, Washing- ton Street, Taunton, Massachusetts, U.S.A. Sept. 12, 1933, No. 25230. [Classes 47 (i) and 47 (ii).] A frangible strut, which on expansion of liquid contained therein bursts and allows operation of a sprinkler head fire door, &c., comprises a vessel of non-corrosive material, preferably of glass, having one open end which is closed by a stopper of non- corrosive material bearing against the mouth thereof without interposed packing, so that there are no forces acting at the joint to split apart or contract the walls of the vessel. The vessel 9 may seat in a stopper 7 which presses a soft metal gasket 8 on the mouth of an opening 3 in the base of a sprinkler head 1. The open end is closed by a stopper 10 with ground surface to contact with the ground mouth of the vessel and a film 20 of sodium silicate may be placed between or the joint may otherwise be protected against corrosive action by an asphaltic mixture. A metal cap 11 surrounds the joint and presses on the stopper 10 through a disc of soft metal 12. It is held in place to maintain the stopper 7 in position by a screw 5 in the sprinkler head which carries a spreader. The seating in the stopper 7 for the vessel 9 may be resilient to permit some irregularity in the shape of the vessel and a spring of sufficient power to maintain the stopper 7 in position even if the tension exerted by the frame 4 varies, may be placed between the bottle and the stopper 7.
