Abstract

161,984. Heide, R. von der. April 21, 1920, [Convention date]. Addition to 156,102. Drawings to Specification. Inhalers and respirators.-Breathing apparatus according to the parent Specification, in which the supply of nutritive gas is automatically controlled by movements of the breathing bag itself, is modified for use with a breathing bag which is supplied with different gases from various sources and mixed while still under pressure. Each inlet valve into the breathing bag from the various sources may be opened or closed by means of a separate pivoted lever or by means of a lever common to all the valves, and means may be provided for increasing the rate of flow of the nutritive gases operated independently of the movements of the breathing bag comprising a pneumatic transmission mechanism similar to that used in the distant release of photographic shutters, or an equivalent device.
