JOHN L. HIVELY, OF ELKHART, INDIANA.

RESPIRATOR OR INHALER.

SPECIFICATION forming part of Letters Patent No. 790,057, dated May 16, 1905.

Application filed June 22, 1904. Serial No. 213,695.

To all whom it may concern: I

Be it known that I, J OHN L. HIvELY, a citiof Elkhart, county of Elkhart, State of Indiana, have invented certain new and useful Improvements in Respirators or Inhalers, of which thefollowing is a specification.

' This invention relates to improvements in respirators or inhalers.

The main object of this invention is to provide an improved respirator or inhaler which is comfortable and convenient to use and simple in structure.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

Theinvention is clearly defined, and pointed out in the claims. 1

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a front elevation View of my improved respirator or inhaler. Fig. 2 is a horizontal sectional view taken on a line corre-' sponding to line 2 2 of Fig. 1. Fig. 3 is'a vertical sectional view taken on a line corresponding to line 3 3 of Fig. 1, the doorC being indicated in its open position by dotted provided with a cushion A, preferably of rubher, which insures a perfect lit, to exclude air and also protects the face of the wearer. The

at one end to serve as a door therefor.

mask A is preferably stamped up from sheet metal, aluminium being preferred on account of its lightness, although any suitable material may be used. A retaining band or strap E, adapted to pass around the back of the head of the wearer, is provided. This band is permanently secured at one end to the mask, and its free end is provided with a snapbutton-socket member a to engage the stud member (4 upon the mask, so that it is quickly secured or detached. A slide-buckle c is provided for adjusting the band.

Secured within the mask in such position as to be supported beneath the nose of the wearer when adjusted for use is a transverselyarranged receptacle B, having perforations b b in the top and bottom thereof, respectively. This receptacle B is filled with absorbent or medicated material F.

The rear wall B of the receptacle is hinged perforations Z) in .the top of the receptacle are zigzagged in relation to the perforations 6 in the bottom.

The mask is provided with a door 0 below the receptacle B for convenience in expectorating or in administering medicine 7 or the like. This door is hinged at the top. Air is admitted to the mask through perforations 0 in the door C. These perforations open into the receptacle C, carried by the door. This receptacle is also provided with a filling of ab- The sorbent or medicated material F. The receptacle C is provided with perforations 0 in its top, adapted to be brought into register with the perforations b in the bottom of the receptacle B when the door is in its closed position, so that the air is first drawn into the receptacle G through the perforations c and passes through the same through the receptacle B.

The reccptacle'C is-provided with a door G.

(See Fig. A finger-piece 0 is provided for the door O. The door C. is held in its open and closed positions by a blade-spring D, which'is secured to the mask and projects downwardly. When the door is open, it is engaged and retained by the lug d on the spring D.

With the parts arranged as described they are very compact, and the structure is very convenient and comfortable to use. The material F for packing the receptacles may be any suitable absorbent or medicated material. I preferably provide an absorbent material for the receptacle C, adapted to collect impurities, and a medicated material for the receptacle F, so that the air inhaled is freed from its impurities and suitably medicated. The medicated material is thus kept comparatively free from impurities, so that it is not necessary to renew the same as frequently as would otherwise be the case.

I have illustrated and described my improved respirator or inhaler mask in detail in the form preferred by me on account of its structural economy and convenience in use. I am, however, aware that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
