RES PI RATO R.
SPECIFICATION forming part of Letters Patent No. 476,486, dated June 7, 1892. Application died February 2, 1892. Serial Nc. 420|l06 (N0 mOdBL) T0 all whom t may concern:
Bc it known that I, Gusrrnvn PozDnNA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain newv and useful Improvements in Respirators, of which the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a view in perspective looking at the outside; Fig. 2, a similar view looking' at the opposite or inner side; Fig. 3, a horizontal section on line 3, Fig. 5, lookingin the direction indicated by the arrow; Fig. 4, a horizontal section on line 4, Fig. and Fig. 5, a vertical central transverse section on line 5, Fig. 3. Fig. 6 is a vertical longitudinal section looking inwardly from the front side.
This invention relates to that class of devices used in protecting the respiratory organs from smoke and noxious gases, and has for its object to provide an arrangement of this character for covering the face, so that the weareris enabled to remain for an indefinite time in an atmosphere charged with smoke or other deleterious gases without inconvenience or injurious ettect.
The device is more especially intended for the use of iiremen or other persons when compelled to pass through smoke in saving life or property, but is also adapted for the use of workmen in factories or other places where the air is charged with poisonous gases or dust-laden with matter of a dangerous character. The construction also makes provision for the protection ofthe eyes as well as the mouth and nostrils.
In the drawings, Ais a casin g or chambered body inclosing the air-passages and which will ordinarily be of the form or contour shown. This casing may be constructed of any suitable material, metallic or otherwise. This casing or body is provided at. its respective ends with doors B B of iine wire-cloth or gauze and hinged, as at d, so that they may be conveniently opened and closed, as may be required. Interior-ly the casing is divided into two distinct passages-the lower inhalin gpassagc C and theuppereXhaling-passage C'-- by a horizontal diaphragm a extending 1" rom end 'to end and located centrally, as indicated by dotted line fc Fig. Il.
The arrows in Figs. 2, 3, andt indicate the course of the air-currents.
Above the air-passage at the receiving end is located the chamber a2, formed by the diagonal imperforate partition a3, inserted between the top of the casing and the horizontal diaphragm a', as shown in Fig. 3. The discharge end is provided with a corresponding chamber a4, the diagonal partition d5, Fig. et, being inserted between the diaphragm a and the bottom of the inclosing casing. The air enters the passage C under charnber a2 and is discharged through passage C over chamber a4. The screen-doors hinged to the respective ends ofthe casing open into the air-passages and the chambers arranged alternately above and below the same. The face side is provided with a V -shaped recess D, extending from the bottom upwardly and terminating in the nose -like projection b. This recess is inclosed by a Haring rim b. having its edge covered by a soft rubber cushion b2 of a tubular structure. The contour of the flaring rim corresponds to and covers the mouth and nose, the rubber border iitting closely to the part ofthe face sura rounding those organs and preventing the admission of air into the respiratory charnber formed by the re-entering recess and rim vexcept through the regular channel. The
flexible apron b3, attached to the upper part of the rim, makes provision for iitting noses of diierent dimensions, so that the face attachment will always be air-tight. The screenprotected aperture d, Figs. 2 and 4, opens in through the recess-wall at the lower right side and is covered by the flexible valve d', fastened along its upper edge, so that the same will open into the respiratory chamber by the pressure of the incoming volume of air, but close from any pressure on the opposite side. The screen-protected aperture d2 opens through the recess-wall on the upper left side and is covered on the outer side from the respiratory chamber with the flexible valve d3, whereby the air inhaled is exhaled through aperture d2. .A screen-partition d4 extends across the inlet-passage from the IOO bottom ot the recess to the inclosing Wall of the casing. A similar partition d5 extends across the discharge-passage. The relative positions of these partitions are indicated in Figs. 3 and 4, being respectively located above and below the central horizontal diaphragm. Thus the incoming current enters under the central diaphragm through the screen-partition d* and passes around the bottom of the recess D into the respiratory chamber through aperture d. The escaping current, after passing out through aperture d2, goes through screen or perforated partition (Z5, around the bottom of recess D, and out. By the construction shown suficient space is provided for the vibration of the flexible valves in the air-passages.
In securing the device to the face the straps e, fastened to the under side of the easing, go around the neck, and the straps e', fastened to the nose part on pins e2, go around the head. The goggles E E are joined by the bow connection g and secured to the pins e2, by the Wire connection g. The transparent part g2 is composed of mica, so as to aord proper protection to the eyes. The straps h provide for securing the goggle attachment in connection with the respirator. rlhe goggles are also provided With the elastic cushionborder h', so that they mayt closely around the eyes.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
l. A respirator-casing provided at its respective ends with doors of Wire-cloth, a central horizontal imperforate diaphragm, inhaling and exhaling passages in different planes, a recess in the face side forming a respiratory chamber, inhaling and exhaling openings in the Wall on opposite sides of said recess and communicating with the respective passages above and below said diaphragm, and flexible Valves covering said openings from opposite sides, substantially as set forth,
2. The combination of the respirator-casing provided on the face side with a recess, as described, the flaring rim inclosing the recessed part, the soft elastic cushion bordering said rim, and the ilexible apron covering the upper part et the rim, substantially as Set forth.
3. A respirator provided With a re-entering recess on the face side forming a respiratory chamber and having the inhaling and exhaling passages in different planes, the screen or gauze partitions located in said passages and extending from the bottoni of said recess to the opposite inclosing Wall, and the valves d d3, substantially as set forth.
