Abstract
A feed bag-like breathing mask for fitting over the forward end of a horse's head, comprises a frame and a bag-like cover carried upon and shaped to closely fit over the frame. The frame is formed of semi-flexible, flat strips providing a rear opening base band for encircling the horse's head rearwardly of the mouth and nostrils, and longitudinal frame strips extending from the base band and joined together at their forward ends. The strips are bent to form an approximately dome-like shape for completely receiving, but being spaced outwardly away from, the forward portion of the horse's head. The cover is formed of a relatively thick, open cell, foamed plastic material. The cells are of a size to substantially freely pass air but to screen a substantial portion of the dust and dirt carried by the air. The cover is sufficiently thick to tend to produce a cold weather breathing cycle wherein some of the moisture in exhaled breath condenses within the cover material, near the inner surface of the cover, to thereby tend to insulate and retain some heat within the mask, and upon exhaling, the incoming dry, fresh air tends to pick up some of the condensed moisture and is somewhat pre-heated before inhaling.
