UNITED STATES PATENT OFFICE W. EVERETT SMITH, OF FRAMINGHAM, MASSACHUSETTS.

DEPURATOR.

SPECIFICATION forming part 01 Letters Patent No. 375.015, dated December 20, 1887.

(No model.)

T0 aZZ w7wm it may concern- Be it known that 1, W. EVERETT SMITH, of Framingham,in the county ofMiddlesex,State of Massachusetts, have invented a certain new and useful Improvementin Apparatus for Administering Medicated Vapors by Inhalation,

'of which the following is a description suffiportion ofthe body removed; and Fig. 3, a

diagram showing a portion of the inhaling apparatus enlarged.

Like letters ofreference indicate corresponding parts in the different figures of the drawmgs.

My invention relates to that class of apparatus for administering medieated vapors by inhalation in which the patient is placed in an exhausted or partially-exhausted receiver or cabinet; and it consists in certain novel details of construction, as hereinafter more fully set forth and claixned, by which a more effective and otherwise desirable device of this chamoter is produced than is now in ordinary use.

The nature and operation of the improvement Will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body, and B the door, of the cabinet. The body is of sufficient size and suitable form to contain the fasten it, by means of the crank-plate f and handle 2, With which thcir inner ends are connected. The crank-plate is also connected with a handle, t, on the inner side of the door in such a manner as to enable a patient within the cabinet t0 readily open the door when disp0scd. The door is provided arouud its edges with rubber or other suitable packing, 7', t0

render it substantiall y air-tight.

Disposed in the front wall of the body A there is a pane of glass, b, through which the patient may be seen when seated in the chair C, and passing through the center of said pane are two metallic or hard-rubber tubes, D E, said tubes beiug provided where they pass through the pane With a suitable packing, H, 130 render thjoint air-tight.

A mouth-pece,.J, preferably composed of glass, and having two laterally-projecting nipples, d l, is connected with the tubes D E by two flexible rubber pipes, K L, the pipe K connecting the nipple 01 and the tube D, and the pipe L connecting the nipplel and tube E. The body of the mouth-piece is enlarged to form the chambcr 9, and provided with a mouth-piece proper, 7L, and downwardly-projecting nipple 72, to which is attached the hollow bulb M, said bulb serving the double purpose ofa handle for manipulating the mouthpiece and a receptacle for the condensed spray or vapor from the ehamber g. The bulb is detachable to enable it to be emptied when necessary. The outer end of the tube D is preferably provided with a flaring or trum pet-shaped mouth-piece, q. It is also provided with a stop-000k, N, and the pipe L with a stop-cock, O.

Attached to the outer end of the tube E there is a flexible pipe, I, which conneets said tube With an ordinary Semple atomizer,R, said atomizer being also connected with an ordinary air-condenser, Q, by et flexible pipe, T, the coupling of which is provided witha stopcock, y.

An ordinary airpump, G, is connected with the body A ot' the cabinet, by means of which the air in said body may be pumped ont or exhausted. A tube passes through one of the side walls of the body A, said tube being provided at its inner end with a stop-cock, 1;, which may be readily opened by the patient in the chair 0 t0 admit air into the cabinet. A tube also passes through the front wall of the body A, said tube being provided at its enter end with a stop-000k, 10, which may be opened by the physician or a person in attendanee on the outer side of the cabinet t0 admit air to the interior of its body if desired.

In theuse of my improvement, the condenser Q being first charged or filied with compressed air, and the stop-000k y closed, and the atomizer B filled with medicated iiqnid, the patient takes his scat in the chair 0 and the door B is ciosed and fastened. The stop-cocks 0 N are then closed and the air in the body A ex hausted or partially exhansted by means of the air-pnmp G, after which the. patient i11- serts the month-piece proper, 71, in his month and opens the stop-cock, 0. The physieian r person in attendance thon opens the stopcocks N 3 and the patient inhaies nntii his longs are fnlly inflated. \Vhen bis iungs are infiated, the patient closes the stop-cock 0 and exhales the vitiated air throngh the pipe K and tube D, the elosed stop-cock O preventing the air as it is forcibiy exhaied from the longs from passing into the atomizer throngh the pipe L and tube E. Aftcr the air is exhaled, as described, the stop-cool; 0 is again opened and the inhalation rpeated.

The medicated vapor from the atomizer as it enters the month-pieee impinges against the wails of the chamber g, thereby eansing a portion of the vapor to be condensed or the surplus 1iquid to be precipitated and to pass into the bulb M, the vapor whieh thereafter passes throngh the mouth-pieee IL being comparativeiy desiceated or dry.

lt will be obvious that the pipe K and tube D not oniy enable the vitiated air from the 1ungs of the patient to be exhaled withont passing throngh the atomizer, but that it also snbserves to admit a quantity of pure air, which is mixed with the medieaued vapor in the chamber g, at eaeh inspiration of the patient, thereby preventing the sense of strangulation which wonld be prodnced by inhaiing a heavily-charged vapor nnmixed with an independent current of nnmedioated air.

in the temporary absence of the physician or attendant the patient may open the door by*means of the handie t, and in case faintness snpervenes he may let air into the cabinet throngh the stop-cock v. VVhen more air is needed in the cabinet at any period dnring the administration of the vapor, the physician or attendant 1nay open the stopcock 10.

It Wili be obvions that when the stopcock 1 is opcned the air from the condenser Q will pass into the atomizer R and vaporize the medieated liqnid contained therein, the medicated vapor thus produeed being constantiy blown through the pipe P, tube E, and pipe L into the month-piece J untii said stop-cool: is elosed.

I do not confine myseIf to the use of any speeial form of air-condenser, air-pump, or atomizer, as any devices adapted to snitably perform the fonctions of these respective parts of the apparatns may be empioyed.

Having thns explained my invention, what I daim is- 1. In an apparatns for inhaling and exhaling n1edicated vapors and atmospheric air,

either separateiy or in a mixed condition, a monthpiece having a chamber in which the vapor and air are mixed on their passage, in combination with a pipe for condncting vapor to said chamber, a pipe for condnoting air to and from said ohamber, and a stop-coek for eiosing said airpipe, said month-piece being provided with an opening throngh which the mixed air and vapor may pass from said chamber into the month of the patient, an opening throgh which air may enter said ehamber fron1 said air-pipe, and anopening through which vapor may enter said chamber frorn said vapor-pipe, snbstantially as described.

2. In an apparatus for inhaiing and exhaling medicated vapors and atmospheric air, either separately or in a mixed condition, an air-tight cabinet, a pnmp for exhansting air theretrom, and a month-pieoehaving a chamber in which the vapor and air are mixed on their passage, in combination with a pipe for con ducting vapor to said eharnber, a pipe for condncting air to and from said charnber, and a stop-cool; for ciosing said air-pipe, said mouth-
