Specification of Letters Patent.

r amed Nov. 6,1906.

Application filed February 19,1906. Serial No. 301,929.

Tov all whom, it may concern:

' Be it known that I, SAMUEL H. MAHAFFY,

a citizen of the United States, anda resident of. St. Louis, Missouri, have invented certain new and useful Improvements in Apparatus for Fresh-Air Treatment, of which the following is a specification.

My invention relates to improvements in apparatus for fresh-air treatment; and it consists of the novel features hereinafter described and claimed.

The object of my invention is to constructa device consisting of a pair of tubes connected to a muzzle and held in position over the nose and mouth of a patient, whereby the atient may inhale fresh air received directly from the outside of .the building without causing the windows to'be opened A further object of my invention is to provide a means whereby a patient may. breathe fresh airreceived from the exterior of the room and a means whereby the air is filtered before entering the apparatus.

' In the drawings, Figure 1 is a viewof the interior of a room, showing a bed and patient with my invention in operative position.

.Fig. 2 is.a side view of my invention, with parts broken away and in section, showing the'construction and application of the device. Fi 3 is a detail sectional iew of a portion 0 the tube, showing my valve in posltion.

My invention consists of a pair of tubes 4 and 5 and a mask 6. The tube 4 is provided with a T joint 7, the outer rojecting portion thereof being provided with a ca 8, which is so arranged as to be removed w on desired.

The end 9 of the tube is held in position upon a nipple 10, which is inserted through the casing 11 of a window, and the outer end of the n1 ple 10 extending into a filtering-box 12. This filtering-box 12 consists of a suitable casing covered with a very fine mesh of cloth to prevent any foreign substancesuch as soot, insects, or the.l1kefrom entering into the nipple 10 and the tube 4. The en 13 of the nipple 4 is held in position upon a nipple 14, formed in the mask 6, and is. ar-- ranged in alinement with the'nostrils of the patient. See Fi 2.)

In the tube a short distance from the nipple 14 I provide a valve 15, which is com-' posed, preferably, of a very soft rubber cone and held in the tube in any desirable manner, the point of the cone bein provided with an opening 16, through whic the air is permit its projecting ted to pass from the exteriorof the building breath during the exhalation of the patient. The end 20 .of the tube 5 is conneced to a nipple 21, extending through the windowcasmg.- The end 22 of the tube 5 is connected .to a nipple 23, formed in the mask 6 below the' nipp e 24, the same in. construction as the valve 15, but reversed in position.

'The mask 6 is provided aroundits contacting edge with a actsas a cushion and which is brought in contact with the face of the patient and arranged to conform with the configuration of theface, and the said mask 6 is held in position upon the face b the band 26, which is placed around the head. v

The object of the T-joint 7 located in the tube 4, is to permit the application of an atomizer. upon the free end thereof, to assume the position as shown-by dotted lines in Figs. '1 and 2, by which medicine may be sprayed into the with the fresh air for penetratin the patient during the inha ation. The

14 and .in alinement with the -mouth of the patient. In thetube 5 a short distance fronf the nipple 23 I provide a valve tube 25, which is inflated and tube and permitted to mix the lungs of valves 15 and 24 are so constructed that dur in the breathing, of the patient the'valve 15 wi 1 permit the fresh air from the exterior of the building to pass through during every inhalation, at the same time closingthevalve 24, and duringeach exhalation the valve 24 will open and the valve 15 close. The valves being made of a very soft rubber substance will close when pressure is brought against the point by compressing against the inner wall of the tube, thereby shutting off the opening. The circulation of air is admitted iai nd discharged as indicatedby the arrows in ig. 2. I

Having thus described I claim as new, me by the grant of Letters Patent is A device of the class described, comprising a muzzle arranged to be placed over the nose my invention, what and mouth of a patient, a pair of tubes connected to the muzzle, both of said tubes extending through the wall of the room to permit the outer 'fresh air to circulate throu h the tubes during the inhalation and exha a5 V I and desire to have secured to IIO tion of the patient, and a pair of valves for regulating the circulation ofthe air during In testimony whereof I have signed my name to this specification 111 presence of two the breathing of the patient, T-joints 10- subscribing witnesses.

cated in the tubes, one tor-admitting the ap- 5 plication of medicine, and the other to receive the condensation of the breath during the exhalation, substantially as specified. I
