Specification of Letters Iatent.
Patented Nov. a, ieo.
Application illed Hatch 12, 190B. Serial No. 420,688.
To all whom it may concern:
Be it known that I, Geenen F. GooDNow, a citizen of the United States, residing in Waukegan, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Respiration-Masks, of which the following is a specification. Those working in or about gas-works are often exposed to escaping gas and many a valved port.
My improved mask, while especially intended `for workmen in gas-works, is also suitable for use by firemen and others who are exposed to noxious gases or vapors of various kinds.
In the accompanying drawings Figure 1 is a perspective view of my improved respiratlon mask and shows also how it is worn. Fig. 2 is a view of the mask on an enlarged scale in vertical central section. Fig. 3 is a perspective view of the mask viewed from the rear.
The bodyortion A of the mask is preferably made o fiexible sheet rubber, that is of substantially hemispherical form, being of such size as to cover the mouth and nose of the wearer and it has a beaded ed e-portion A whichl is hollow and inflata le. The beaded portion is formed with a art a ada ted to fit snugly the brid e of tll'ie nose, whi e the lower portion a2 ts under the chin and the sides aB fit clsely the cheeks. Preferably the portions aa are somewhat larger in area than the portion a. The hollow beaded ed e may be inflated or deiated by the valved branch-pipe B.
A front-plate C is a plied to the outside of the front of the mas and a back-plate D is applied centrally to the rear of the front portion thereof. The plate C is formed with radiall extending arms c, c', some' of which c lie at against the mask while others c are bent outwards to provide means for attaching the straps v-E which secure the mask to the head of the wearer; The arms c serve to keep the bodyl of the mask in shape and to hold it firmly in place on the face. The front-plate has two apertures and G and the back-glatehas two registering apertures H and The mask has 'corresponding a ertures between these openings. A coup ingy J is secured to the mask at the apertures F, H and through this coupling air is admitted tothe mask. As shown, the coupling is L`shaped and has a portion j which passes through the body of the mask and through the apertures F, H, and it is shouldered at j to fit snugly against the front-plate and threaded at i2 to receive the threaded part fm of the valvecasing M.
The valve-casing is open at its inner end and at the sides and has a valve-seat m to receive the disk-valve N which is preferably of mica. The arrangement is such that air can be drawn in through the coupling but cannot be forced outwards therethrough. The coupling J is connected to a light, flexible hose O which passes over to the back of the wearer and down to the waist where it is connected to a stouter hose P which should be of considerable length in order to pass out to the fresh, pure air. The inner end of the hose is supported on a belt Q ap lied to the wearer and at the outer end ci) the hose there is a funnel-shaped receiver Q through which air can readily enter, especially when the receiver is turned against the wind.
A valve-casing R is attached to the mask by means of a coupling R which extends throu h the mask and through the apertures G an Iand this valve-casing has a diskvalve S which prevents the entrance of air, gas or smoke but which opens to permit the exhalations'from the wearer of the mask to pass out.
Experience has demonstrated that a. mask constructed in accordance with my lnvenweight of the mask and a comparatively l short, light lenth of hose which is also partially supporte by the belt. The construction is such that the mask can be conveniently manufactured and assembled and when assembled all leakage is entirely prevented.
It will be observed that the couplings for the valve-casings are clamped against the front and rear plates which compress between them the rubber mask proper, thus insuring a packed joint. The arms of the front-plate serve to keep the bod of the mask 1n shape as well as to provi e means for attachin the securing straps at proper places to hol the mask firmly in place.
I claim as my invention:
'A respiration-mask comprising a bodyportion, a front-plate having radially extending arms bearing against the front of the mask and some of which are bent outwardly, straps attached to the bent arms for securing the mask to the face of the wearer, a back-plate within the mask and valved entrance and exit couplings applied to said l plates.
In testimony whereof, I have hereunto subscribed my name.
