PROVISIONAL SPECIFICATION.
Improvements in Inhalers and Respirators.
I, JOHN ALFRED PERON, of 1469 First Street, San Diego, California, United
States of America, Agent, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to an arrangement of inhaler and respirator proposed to
be worn under the lips and over the teeth, the primary object being to prevent
cold air to pass direct to the lungs; by the use of this invention such air has to
take a deviated course, and the user gradually comes to keeping the mouth closed
and breathing through the nostrils: the invention also being suitable for use
during sleep without possibility of it getting into the mouth.
The respirator consists of a plate of a shape to fit in under the lips and over the
teeth, and may have an absorbent substance attached to absorb and hold any
medicinal preparation to be inhaled. To prevent the plate working into the mouth
if worn during sleep, one or more guards with T-shaped ends are attached, and
detachable at will; the top of the T-part standing over the lips on outside.
Dated this 30th day of March 1892.

COMPLETE SPECIFICATION.
Improvements in Inhalers and Respirators.
I JOHN ALFRED PERON of 1469 First Street San Diego, California, United
States of America Agent do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
My invention relates to an improvement in devices which are worn to prevent
direct breathing through the mouth and has for its object to provide such an
appliance with exterior guards that will prevent the device from entering the
mouth or throat of the wearer accidentally. To this end my invention consists in
the peculiar construction of the device hereafter described and claimed. Reference
is to be had to the accompanying drawings, forming part of this Specification in
which similar letters of reference indicate corresponding parts in all the views.
Figure 1 is a view of the device within the mouth of a person its outline being
indicated by a dotted line and the guards therefor in full lines exterior of the
mouth.
Figure 2 is a perspective view of the appliance removed from the mouth: and
Figure 3 is a transverse sectional view of the device in position within the closed
mouth of a subject also shewn in section.
The principal portion A of the appliance consists of a plate made of a suitable
material and a length proportioned to the capacity of the mouth and size of the
lips of the wearer it being contemplated to provide a gradation of sizes to suit each
variations of dimensions in mouths of patients as may be found necessary.
As indicated in Fig. 2 the plate A is rounded on its ends and and undulated on
the upper edge longitudinally. considered, to adapt it to fit within the space that
intervenes between the lips and exterior surface of the gums and teeth so that
the plate may be readily introduced and rest without discomfort in the channel
mentioned and represented at a in Fig. 3. In order to retain the device from
displacement and prevent the entrance of the plate A within the mouth or throat
f27

page_text: of the wearer when asleep there are guard limbs be projected outwardly from the
exterior surface of said plate a sufficient distance to pass between the lips of
the patient and then bent in pairs oppositely, so that the limbs will rest near to the
upper and lower lips. When the device is in place, the length of these external
limb portions being sufficient to adapt them to serve as a guard to prevent the
involuntary reception of the plate and limbs within the mouth during the hours of
sleep.
The introduction of the plate A in the manner stated forms a barrier to the
free inhalation of air between the parted lips and in consequence the act of breathing
is performed through the nostrils as nature intended, thus obviating the injurious
effect of a direct introduction of cold air into the throat, bronchial tubes and lungs,
as well as the prevention of the habit of snoring.
After the wearer has become habituated by the use of the appliance to retain
the mouth closed and breath through the nasal passages the wearing of the
controller may be discontinued and may not be again required.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A breath controller consisting of an elongated plate made to fit in the space
between the lips and teeth or gums of a person and provided with oppositely
projecting guard-limbs that may engage the lips exteriorly, substantially as
described.
2. A breath controller to prevent the direct inhalation of air through the mouth
to the lungs, consisting of an elongated thin plate having its edges shaped to
conform with the channel between the lips and gums and teeth of the wearer and
provided with two pairs of guard-limbs that project outwardly and are then bent
oppositely in pairs to be near the exterior of the lips when in service substantially
as described.
