Respirators

Claim 2

A respirator comprising a. an elongated tubular housing having a mouthpiece at one end thereof for insertion into a person's mouth to thereby enable the person to 1. inhale in one direction longitudinally through said housing, and 2. exhale longitudinally through said housing in the direction opposite to said one direction, and b. means in said housing for vibrating material inhaled and exhaled therethrough, c. said housing having two passageways extending longitudinally through at least a portion thereof in side-by-side relation to each other, d. said means for vibrating material inhaled through said housing comprising means mounted in one of said passageways, e. said means for vibrating material exhaled through said housing comprising means mounted in the other of said passageways, f. each of said passageways having

Claim 3

an annular valve seat mounted therein for the passage of such material therethrough, 2. a valve member mounted therein in position to be moved into and out of closing engagement with said valve seat, 3. spring means mounted therein and yieldingly engaged with said valve member for yieldingly holding said valve member in said closing engagement with said valve seat, and 4. a retainer member mounted therein and engaged with said spring means on the side thereon remote from said valve member in position to hold said spring means in engagement with said valve member, g. said valve seats being threaded into respective ones of said passageways and being adjustable longitudinally thereof, h. said retainer members being threaded into respective ones of said passageways and being adjustable longitudinally thereof, i. said valve member in said one passageway being disposed in said closing engagement during such exhalation through said housing, and j. said valve member in said other passsageway being disposed in said closing engagement during such inhalation through said housing.

Claim 4

an annular valve seat mounted therein for the passage of such material therethrough, 2. a valve member mounted therein in position to be moved into and out of closing engagement with said valve seat, 3. spring means mounted therein and yieldingly engaged with said valve member for yieldingly holding said valve member in said closing engagement with said valve seat, and 4. a retainer member mounted therein and engaged with said spring means on the side thereon remote from said valve member in position to hold said spring means in engagement with said valve member, g. said valve seats being threaded into respective ones of said passageways and being adjustable longitudinally thereof, h. said retainer members being threaded into respective ones of said passageways and being adjustable longitudinally thereof, i. said valve member in said one passageway being disposed in said closing engagement during such exhalation through said housing, and j. said valve member in said other passsageway being disposed in said closing engagement during such inhalation through said housing.

Claim 5

A respirator for a person suffering from emphysema, or the like, for causing vibration of air in the person's lungs, comprising a. an elongated tubular housing having a mouthpiece at one end thereof for insertion into a person's mouth to thereby enable the person to 1. inhale in one direction longitudinally through said housing, and 2. exhale longitudinally through said housing in the direction opposite to said one direction, b. said mouthpiece having an unobstructed, continuous outer peripheral surface of such size as to be completely surroundingly engaged by the lips of such a person during such inhalation and exhalation therethrough, c. means in said housing for vibrating material inhaled and exhaled therethrough, d. valve means for limiting inhalation and exhalation through said housing, e. said housing having two separated passageways extending longitudinally through at least a portion thereof, f. said means for vibrating material inhaled through said housing comprising means mounted in one of said passageways, g. said means for vibrating material exhaled through said housing comprising means mounted in the other of said passageways, h. said valve means comprising 1. a one-way valve mounted in said one passageway for permitting inhalation and preventing exhalation therethrough, and 2. another one-way valve mounted in said other of said passageways for permitting exhalation and preventing inhalation therethrough, and i. means disposed on said housing between said first mentioned means and said mouthpiece for feeding auxiliary material into said housing for inhalation through said mouthpiece.

Claim 6

A respirator for a person suffering from emphysema, or the like, for causing vibration of air in the person's lungs, comprising a. an elongated tubular housing having a mouthpiece at one end thereof for insertion into a person's mouth to thereby enable the person to 1. inhale in one direction longitudinally through said housing, and 2. exhale longitudinally through said housing in the direction opposite to said one direction, b. said mouthpiece having an unobstructed, continuous outer peripheral surface of such size as to be completely surroundingly engaged by the lips of such a person during such inhalation and exhalation therethrough, c. means in said housing for vibrating material inhaled and exhaled therethrough, d. valve means for limiting inhalation and exhalation through said housing, e. said housing having two separated passageways extending longitudinally through at least a portion thereof, f. said means for vibrating material inhaled through said housing comprising means mounted in one of said passageways, g. said means for vibrating material exhaled through said housing comprising means mounted in the other of said passageways, h. said valve means comprising 1. a one-way valve mounted in said one passageway for permitting inhalation and preventing exhalation therethrough, and 2. another one-way valve mounted in said other of said passageways for permitting exhalation and preventing inhalation therethrough, and i. means disposed on said housing between said first mentioned means and said mouthpiece for feeding auxiliary material into said housing for inhalation through said mouthpiece.

Claim 7

A respirator as defined in claim 2, and in which a. said first mentioned means vibrates said air passing through said housing at a frequency not substantially less than 100 vibrations per second and not substantially more than 300 vibrations per second.
