FACE-MASK.
Speeification of Letters Patent.
Application filed December 16, 1912.
Patented Nov. 4, 1913.
Serial No. 737,158.
To all whom it may concern:
and efiicient means of protecting the face" and filtering the air before it enters the lungs of the wearer. I
Therefore, the object of the present invention is to provide a face mask which can be worn with a great degree of comfort, since it provides cushioned parts to contact with ample' space in the front of the mask, which is covered by a transparent element, to enable the wearer to easily see to perform his work. The mask also provides an air chamber in front of the face which is automatically exhausted of its foul contents, and in turn receives a supply of fresh air.
With these and other objectswhich will more readily appear as the description of the case proceeds, the invention consists in the novel construction, combination, and arrangement ofparts hereinafter more fully described, illustrated, and claimed.
A preferred and practical embodiment of the invention is shown-in the accompanying drawings, in which Figure 1 is a front elevation of the present invention adjusted to the head of a person. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical section of a modification of the invention applied to the face of a person. Fig. 4 is a detail sectional view of the cushion element. Fig. 5 is a detail elevation of the outlet valve. Fig. 6 is a sectional view of the exhaust valve.
Referring specifically to the several figures of the drawings, the numeral 1 designates the body of the "mask which is of a shape that conforms with the general features of the human face. The said body 1 is preferably made of aluminum, though other materials may be used with advantage, and is Be it known that we, HENRY C. GRAYBILL and ADOLPH C. ERGLER, citizens of the United States, residing at Altoona, in theT county of Blair and State of Pennsylvania, have invented certain-new and useful Im- I provements in Face-Masks, of which the fol:
provided around the outer edge thereof with an annular recess 2 which has formed in the wall thereof a plurality of openings 3. The frame '1 also has suitably located around the outer edges thereof theeyes 4, through which are passed suitable attaching straps 5, which are designated to fit over the head of the wearer and hold the mask in place.
Located within the annular recess 2 is an elastic tube 6 which is provided with the valve 7 in' order that it may be inflated and thereby form a cushion, which will snugly fit the face of a person using the mask and prevent smoke or bad air from entering under the side edges of the mask. The said tube 6 is provided with a plurality of resilient projections 8 which-are provided with a central cavity 9. These projections 8 are adapted to enter the openings 3 in the. wall of-the recess2jand neceive in their central cavity 9 a screw; 11 or equivalent wedging element. The effect of the screw 11 upon being forced in the cavity9 is to press the side the face of the wearer and also provides walls of the projections into engagement with the walls of the hole 3, thereby holding in place the inflated cushion tube 6. In connection with the tube 6, it will be observed that there is a felt or equivalent lininglO interposed between the tube and the body to prevent the rubber from coming in direct contact with the metal of the body- The front of the body portion 1 is pro"- vided. with an opening which extends approximately'across the entire front of the upper part thereof, and is fitted with a transparent element 12. This transparent element which may be of glass or mica is the mouth of the person wearing the mask,
which gives him free access to the fresh air drawn in by inhalation.
Off to one side of the fresh air intake, there is provided .an exhaust opening 19 which is adapted to be covered by the spring-pressed valve head '20. In order to prevent the valve from coming too far ofi' its seat on the body 1, there is fitted over the top thereof a cover 21. This valve, of course, only allows air exhausted from the lungs to escape and prevents any foul air from enterin at this point.
In the modification illustrated in Fig. 3, instead of a filter cup such as is'used in the other application of the invention, the intake opening 15 has attached thereto a tube 22 which extends to a suitable source of fresh air supply, not shown.
From the foregoing description, the many advantages of the present invention will be readily understood without further comment.
We claim:
1. A face mask comprising a body provided with an opening in the front thereof, and an annular recess having a wall provided with a plurality of openings, a tube adapted to be inflated and thereby form a cushion located in said annular recess, resilient projections provided with a central cavity, said projections adapted .to enter the openings in the wall of said annular recess, means for entering the cavity of said projections and expanding the same into firm engagement with the walls of the openings in the recess, a fresh'air su ply inlet, an exhaust valve, and head attac ing means.
2. A face mask comprising a body provided with an opening in the front thereof, and an annular recess having a wall provided with a plurality of openings, a tube adapt ed to be inflated and thereby form a cushion located in said annular recess, means on said tube for entering the vopenings in the wall of the recess, means for attaching the tube to the body of the mask, a transparent element fitted to the body and covering the opening in the front thereof, means for holding the said element in place, an air intake member containing a filtering medium associated with the body, an exhaust valve comprising a spring pressed valve head, and a cover therefor, and means for securing the mask to the head of the wearer.
In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
