PROVISIONAL SPECIFICATION.
Improvements relating to Inhaling Masks or Cups and the like.
I, CHARLES HENRY GORRINGE, of 5 Furnival's Inn, Holborn, London, W.C.,
Solicitor, (a communication from abroad by Harley Mitchell Dunlap, of Battle
Creek, in the County of Calhoun and State of Michigan United States of America,
Doctor of Medicine), do hereby declare the nature of this invention to be as
follows:-
My invention pertains to a new cushion for the edges or margins of inhaling
cups or masks and the like, and the object of my invention is to provide a cushion
around the margin of the masks or cups which may be conveniently and
expeditiously placed in position thereon, or removed therefrom, for the purpose
of cleaning or disinfecting, and which shall be at the same time elastic, pliable
and readily adaptable to the conformation of the face around the nose and
mouth.
The invention consists in the provision of a retaining flange or lip around the
edge of the mask or cup which may extend outwardly or inwardly; such retaining
flange or lip is provided for entry into a corresponding recess formed within a
cushion of indiarubber, caoutchouc, or other similar substance which I provide
thereupon, and which by means of the transversely extending flange or lip retains
the cushion in position and at the same time allows its ready removal as occasion
requires. I provide my cushion with an annular chamber disposed immediately
above the edge or margin of the cup, which may be supplied with air at normal
atmospheric pressure, or when less flexibility is required, at a pressure above that
of the atmosphere. It is obvious that by this construction of cushion an easy and
convenient means of attachment to the mask or cup is obtained without the use of
any cement or adhesive material, while the pneumatic cushion provides a sub-
stantially air tight seal between the cup mask and the face of the patient, and is at
the same time itself comparatively inexpensive of production.
1 may preferably form my retaining lip or flange of a T section in which the
lips or flanges are transversely disposed to the sides of the cup or mask itself while
I may also provide my air annular chamber in one with the recess which is formed
for embracing the retaining flanges of the cup.

I, CHARLES HENRY GORRINGE, of 5 Furnival's Inn, Holborn, London, W.C.
Solicitor, (a communication from abroad by Harley Mitchell Dunlap, of Battle
Creek, in the County of Calhoun and State of Michigan, United States of America,
Doctor of Medicine), do hereby declare the nature of this invention and in what
PQ71

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention pertains to a new cushion for the edges or margins of inhaling
cups or masks and the like, and the object of my invention is to provide a cushion
around the margin of the masks or cups which may be conveniently and
expeditiously placed in position thereon, or removed therefrom, for the purpose
of cleaning or disinfecting, and which shall be at the same time elastic, pliable
and readily adaptable to the conformation of the face around the nose and
mouth.
In the accompanying drawings-
Figure 1 is a perspective view of an inhaling cup or mask having a cushion
margin applied; while
Figure 2 is a section through x y Figure 1, and
Figure 3 is a part section of a modified arrangement.
My invention consists as illustrated in the accompanying drawings in the
provision of a retaining flange or lip a around the edge of the mask or cup b which
may extend outwardly as in Figure 2 or inwardly; such retaining flange or lip is
provided for entry into a corresponding recess formed within a cushion c of india-
rubber, caoutchouc, or other similar substance which I provide thereupon, and
which by means of the transversely extending flange or lip a retains the cushion in
position and at the same time allows its ready removal as occasion requires.
provide my cushion with an annular chamber d disposed immediately above the
edge or margin of the cup, which may be supplied with air at normal atmospheric
pressure, or when less flexibility is required at a pressure above that of the
atmosphere. It is obvious that by this arrangement of cushion an easy and
convenient means of attachment to the mask or cup is obtained without the use of
any cement or adhesive material, while the pneumatic cushion provides a sub-
stantially air tight seal between the cup mask and the face of the patient, and is at
the same time itself comparatively inexpensive of production.
The cup or mask is provided with the usual iulet opening in connection with
which a tube e is employed to receive a flexible connecting tube from the gas or
other supply.
I may preferably form my retaining lip or flange a of a T section as illustrated
in Figure 3 in which the lips or flanges a are transversely disposed to the sides
of the cup or mask itself while I may also provide my air annular chamber in
one with the recess which is formed for embracing the retaining flanges of
the cup.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is―
a
(1.) A cushion for inhaling masks or cups, or any similar article requiring
cushioned margin, said cushion consisting of a tube provided with a depending
section arranged to receive the flange of the mask or cup, substantially as
described.
(2.) A cushion for inhaling masks, cups and other articles, comprising an
inflatable section and an attaching section, the latter being arranged to receive a
flange upon the article to be cushioned, substantially as shown and described.
(3.) A cushion for inhaling masks or cups, or other articles, the same comprising
a tube adapted to contain air, and a depending section slotted correspondingly to
the shape of the marginal portion of the cup or mask which said depending section
is adapted to embrace, as and for the purpose specified.
(4.) The combination, with an inhaling mask or cup, or a similar article provided
with a flange, of a cushion provided with an air chamber, and a depending section
slotted to receive the marginal portion of the cup or mask together with the said
flange, as and for the purpose specified.

page_text: (5.) The combination, with an inhaling mask or cup, the same being provided
with a flange formed upon its marginal surface, of a cushion provided with an air
chamber and removably connected with the said cup or mask and having a slotted
section receiving the said flange, as and for the purpose specified.
(6.) The combination, with an inhaling mask or cup, of a cushion having a
continuous opening formed in its lower edge, adapted to receive the marginal
portion of the cup, or mask, as and for the purpose set forth.
