    Specification. Carriers Improvements in Respiratory Apparatus. liquid or dry, with which it is desired the air to be inhaled should come in contact and be impregnated. Fourth, the regulation of the temperature of the air to be inhaled, either at high or low degrees of heat, and either by natural or artificial means in con¬ nection with this portable apparatus, which may be worn on the person or 5 remain detached therefrom, as may be desired. The means by which these improvements in respiratory apparatus are carried out may be generally described as follows: —The inhaling apparatus consists of a chamber having two orifices. This chamber is so shaped as to fit the mouth of the wearer, permitting the ingress and egress of the air only to take place through the 10 openings before named. To the egress aperture a delicate self-acting valve is attached, which while it permits the free exit of the respired air effectually closes and prevents any return of the external atmosphere, which is therefore forced to enter the lungs by the other aperture. The medicating chamber, which may be used at the same time to regulate the temperature of the 15 inhaled air consists of a portable vessel closed to the egress and ingress of the atmosphere, except through its tubes or other connections with the respiring apertures of the respirator or inhaler. This portable vessel may be made of such a shape as to be worn underneath the garments, and may contain, if necessary, one or more chambers to hold liquid or other materials intended to 20 medicate or purify the inhaled air. This vessel may be either cooled or heated by artificial means other than the natural temperature of the body.
