    2 N° 17,732.—A.D. 1893. Portable Apparatus for Treating a Patient with a Medicated or Tempered Atmosphere_ 2. The medicating or tempering vessel B, shewn in section in Fig. 2, is made of metal internally tinned and is covered by a hinged lid Q which can be tightly closed on a washer of caoutchouc. A nozzle R, provided with a spring check valve T, admits the air from the pump G. A stop cock t serves to drain off moisture or other liquid. A valved outlet X has a nozzle X1 to which is attached 5 the flexible pipe Gf which leads into the upper portion E of the dress A. Within the vessel are several perforated diaphragms V on which are placed pine shavings impregnated with antiseptic or other medicaments which can be introduced by a filter Z, having two cocks, against the internal pressure which can be regulated as desired by an adjustable spring safety valve s1. The diaphragms V are all attached 10 by a central bolt to the uppermost V1, which rests on a shoulder, so that they can all be lifted out together. The vessel B is furnished with a pressure gauge u. By heating or cooling the vessel B, the air supplied to the patient may be varied in temperature. 3. The pump C, of which Fig. 3 is a vertical section, and Fig. 4 also a vertical 15- section on the line cd of Fig. 3, consists of two cylinders containing a quantity of water which, by means of a packed piston 1 worked by lever 2 in the one cylinder 3, is caused to moA'e up and down in the other cylinder 4, thus causing air to be expelled by valve 8 and drawn in by valve 7. By applying the piston to move the water, the air pumped is not affected by the lubricant employed for the 20' piston. 4. Besides the pipe o for supplying the patient with liquid, there is the flexible pipe R connecting the discharge nozzle 9 of the pump to the vessel B ; there is the flexible pipe Gr connecting the nozzle X1 of the vessel B to the upper part E of the dress A preferably behind the patient’s neck, and there is finally the pipe H 25- for escape of air from the interior of the dress, as determined by an adjustable valve P. Having now particularly described and ascertained the nature of this inven¬ tion and in what manner the same is to be performed, I declare that what I claim is 30 1. The air tight dress A and mask i with the impermeable jointings, substantially as described. 2. The medicating and tempering vessel B with its fittings, substantially ns described. 3. The pump C with water piston, substantially as described. 35 . J^ie P*Pes. R and Gr connecting the pump C and vessel B to the dress A, the pipe II and adjustable valve P for escape of air from the dress, and the pipe o with valve, nozzle and stopper, substantially as described. 5. rhe combination of the parts referred to in the preceding claims, constituting portable apparatus for treating a patient with'a medicated or tempered atmosphere, a(\ substantially as described. ^ Dated this 21st day of September 1893.
