Abstract

533,386. Respiratory appliances. DAVIS, Sir R. H. Oct. 7, 1939, No. 27451. [Class 81 (ii)] In a respiratory appliance provided with a warning device for indicating a deficiency in the supply of gas, the warning device consists of a baffle 6 mounted in the exhaling tube and moved by a device responsive to pressure in the gas supply, e.g. a Bourdon tube, to obstruct the exhalation pipe thereby causing a whistle 7, mounted on the baffle to be operated by the increased pressure in the obstructed pipe. The Bourdon tube 2 is connected to the gas supply 1 and actuates the shaft 5 of the baffle 6 through linkage 3, 4.
