' ANESTHETIC-MASK.
To all-whom it may concern:
Be it knownthat we, WILL P. WALTER and DAVID G. McCURDY, citizens of the United States, and residents of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Anesthetic-Masks, and we do ence being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to a face mask for .use with apparatus designed for administering anesthetics, analgesics and the like and consists of the matters hereinafter described and more particularly pointed out in the appended claim. i
The object of the invention is to provide a mask of the kind which will adhere closely to that part of the face which it engages, so as to entirely block and prevent the entrance of outside air under the mask.
The improved mask is constructed either in such manner as to cover only the nose, leaving the mouth free, or so as to cover both the nose and the mouth. In the former case the mask is designed more particularly for use where an operation is to be performed in the mouth as in dentistry or in the treat-.
ment of the throat, tonsils, and the like. The form of the mask covering both the nose and the mouth is preferable for the general administering of anesthetics, as the inhalations and exha'lations may be made either through the mouth, or nose, orboth.
In the drawings:
Figure 1 is a perspective view of the improved mask applied to cover both the nose and the mouth.
Fig. 2 is a perspective view, showing the form of mask which is adapted to cover only the nose as it ap ears when applied in use.
Fig. 3 is a perspective View of the type of mask shown in Fig. 1, looked at from the rear of the mask.

adapted to cover both'the nose and mouth of the patient. Said mask has a substantially cup-shaped body with an aperture or opening 11, at one end, or in what would be the bottom of the cup, for the attachment of a valve piece 12, that may be connected to any suitable apparatus for the administration. of the anesthetic.
13 indicates the base of the mask; that is to say, the part which is intended to close on the'face. The mask is made of heavy, flexible, elastic material such as rubber, the wall being made sufficiently heavy so that it will not collapse but will stand up and maintain its form with substantial rigidity under the pressure required to hold it tightly engaged against the face. A notch 14 is formed at the base of the mask to embrace the sides and top of the nose. A depression 14* is formed in the opposite side of the base to fit the chin below the lips.
The marginal wall is tapered gradually toward the base to a substantially thin edge 13*. In tapering the marginal wall, the taper is formed from the inside toward the outside, so that the thin edge 13 is preferably in the outer surface ofthe mask wall and not in a line intermediate the inner and outer surfaces. The taper is begun on the inner mask-wall surface in a line 13*, which is spaced a distance above the edge 13 considerably in excess of the thickness of the mask wall. A comparatively long, thin,
flexible, marginal taper is thus produced to air tight engagement against the faceabout the parts inclosed by the mask.
The mask is held in place by means of straps, or bands, 15, attached to its opposite sides in any convenient, well known manner.
The mask for covering the nose is made in substantially the same way as that which covers both the mouth and nose, except that it is smaller in diameter, and is designed only to inclose the space about the nostrils, leaving the mouth exposed.
10 indicates the nose mask, The parts of the mask which correspond to the-"parts of the nose and mouth mask are indicated with the same reference numerals.
The many advantages of the improved mask will be manifest to those familiar with the art. It is easily and readily seated so as to entirely inclose the inhaling part in a gas. tight pocket and Will at the same time maintain its shape so as to efficiently accom plish its intended purpose. It covers only the parts of the face which are closely adjacent to the organ or organs that are to be inclosed.
\Ve claim as our invention:
A. mask of the kind described, consisting of a cup-shaped body provided with an aperture at one end for the attachment of a valve piece, said body having a comparatively thick wall made of heavy, flexible, elastic material, and having a base formed to follow the general contour of the face in the neighborhood of the part to be inclosed, the margin of the wall at the base being beveled from the inside outwardly to provide a Wide. tapered surface extending entirely around the periphery of the base and being adapted to spread outwardly so that said marginal, tapered surface may be brought into close, seating engagement against the face about the parts inclosed by the mask.
In testimony that We claim the foregoing as Our invention we affix our signatures in the presence of two Witnesses, this th day of April, A. D. 1916.
