COMPLETE SPECIFICATION.
An Appliance for the Effectual Prevention of the Inhalation of the
Breath from Diphtheric and other Patients, and Germs from
the Excreta of and Malodours from those Suffering from other
Infectious Diseases.
I GEORGE CHEVELEY STENNING of 184 Blomfield Terrace, Bayswater,
London, W. Esquire do hereby declare the nature of this invention and in what
inanner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
This invention relates to apparatus (capable of being held with ease in the
mouth) fitted with a clip to compress the nostrils for effectually preventing the
inhalation of contaminated air by the wearer. Respiration is freely obtained by
means of two tubes connected by a pouch which hangs between the shoulders.
The upper part of the pouch is furnished with a sponge charged with a disinfectant
through which the air inhaled filtrates or through wire cages at the tube ends.
The invention will be found applicable in the following cases. By doctors when
attending diphtheric typhus and other infectiously diseased patients and when the
operation of tracheotomy is performed, also when examining the excreta in
infectious diseases and particularly at post-mortem examinations and when brought
into contact with bad odours.
By nurses it will be found invaluable in the performance of their services as it
can when not in actual use hang on the shoulders and be instantly adjusted when
required.
By jurymen when viewing dead bodies and at coroners inquests.
By sanitary inspectors and engineers.
By the employees in chemical works, in cement and other mills and when metal
or other particles injurious to the respiratory organs infect the atmosphere.
My invention is clearly shown in the annexed drawings.
Figure 1, a part sectional elevation of the complete apparatus.
Figure 2, a cross section through the mouthpiece.

to suit the facial angle of the wearer.
Figure 4 an end view to show the holes for the adjustment of the screw pads to
suit persons having a deep or a shallow upper lip.
Figure 5 represents plan of a pocket apparatus in which the saturated sponge is
held in net work chambers at the ends of folding tubes.
A is a cylindrical or other shaped casing with end branches B, B, projecting
from either side for the ready attachment of flexible tubes C, C, said tubes
descending and terminating in a pouch or open mouthed bag D into which sponge,
cotton wool or other air clarifying agent can be placed saturated with a disinfectant
or other body as desired.
The casing A has a recessed front E and this is provided with a mouthpiece F,
fixed or movable, and if the latter it can be pushed in or drawn out at the desire
of the person using the apparatus, said mouthpiece being preferably covered with
a thin skin, say india rubber F1 as a soft and yielding medium to the touch of the
persons teeth.
Above the front plate E is affixed a hinged bar G which serves to secure a
folding plate H of one side lug I as part of the pince-nez, the other half being
formed of a movable leg J of the other half pince-nez which is to be slid along in
a slot of the plate H for adjustment as to width of a persons nose.
The pincer
part of this portion of the apparatus is arranged at an angle and is composed of
two short pieces of metal K with screw threaded holes; the threaded stems L of
the pads M can be arranged at a higher or a lower level as desired.
According to the modification shown at Figure 5 the branches have ends, hinged
to them for folding inwardly as indicated for pocket carriage the ends being of wire
work as terminals N for holding saturated or impregnated sponge.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The apparatus shown on the annexed drawings consisting of shell A, branches B,
fixed or movable mouthpiece F and pince-nez, the whole being connected to a
pouch by tubes C substantially as and for the purpose or purposes described.
