Abstract

190,645. Drager, A. B. Jan. 9, 1922. Respiratory appliances.-Relates to breathing- apparatus for use in noxious gases of the type having an air-purifying cartridge p, an oxygen container f, a mouthpiece m and a breathing-bag s together with the necessary connecting pipes and valves. In order to maintain sufficient air pressure, in such apparatus to overcome the tendency for the outside gases to enter at leaky parts, the breathing-bag is provided with springs n, o which tend to make it assume its deflated form. Modifications in which the springs are external to the bag are described.
