In the drawing:

Figure 1 is a front view of the mask showing the manner in which it fits on the face of the wearer and also the means for holding it in place on the head,

Figure 2. is a side elevation of the same; and

The tubes 9 and II are made of molded rubber and are so shaped as to give a clamping action on the head, thereby in front ofthe I along the headband so serving to hold the mask firmly in place on the face of the wearer. The tubes 9 slidably enter the mask through a sleeve joint I and the mask' may be made to fit difierent individuals by sliding the tubes 9 in or out of joints [0 until a pro-per fit isarrived at whereupon the tubes are cut off and cemented in place. i

A fabric'headband l3 fits snugly around the top of the head and aids in supporting the mask. To this end, slide fasteners I4 are provided which encompass the tubes 9, as shown, and which :are V slidable along the band 13. By sliding the tubes;

A respirator mask comprising a layer of resilient material having such shape as to fit the face of the wearer around the nose, cheeksand chin, and spaced from-the face in the vicinity of the mouth andnostrils, a fluid-conveying conduit attached to each side of the mask and extending upwardly along each side of the wearers head to the crown thereof, a single conduit formed bythe-unionof said-individual conduits 10.
