Abstract

547,127. Sprinkler apparatus. ELLIS, O. W. Aug. 4, 1939. No. 22693. [Class 47 (ii)] Automatic sprinklers are operated by thermally responsive elements comprising metals alloys or non- metals with different coefficients of expansion in the form of strips 55, Fig. 3, to which latches 52 are attached. These latches support valves 46 closing tubular passages 35 until predetermined temperatures higher or lower than room temperatures are reached whereby the thermally responsive elements change their shape and release the latches and thus unseal the valves. The valve 46 has a head 49 sealed with paraffin wax 50. When the element 55 changes shape and releases the latch 52 the valve 46 drops and fluid passes out by passages 43. An adjustment to the movement of the thermal element 57, Fig. 9, may be made by a nut 62 which can act anywhere in a longitudinal slot in the element. In a modification Fig. 12, the thermally operated valve apparatus is supported on a bracket 66. In another modification, Fig. 20, a valve 89 is supported by a latch 88 thermally operated by a member 90.
