    Specification. Barth's Improvements in Administering Gases for Curative Purposes. a glass mouthpiece. Between the mouthpiece and the gasometer is a vessel containing two valves, one allowing the gas to be inhaled, and the other allowing it to escape into the room after having been respired. The gasometer is supplied from a strong wrought iron vessel, which may be placed under the pedestal or in the core or cylinder before mentioned. The gas is compressed 5 into this vessel by a force pump, and a sufficient quantity may be contained therein to supply the patient for a considerable period. When one vessel is empty another one ready filled may be connected with the gasometer. It is obvious that many different arrangements of apparatus may be employed in effecting these objects, the main feature of my Invention being the supplying 10 in a portable and compact form gases for medical use by compressing the same in strong chambers.
