PROVISIONAL SPECIFICATION.
Improvements in and relating to Respirators.
I, MATHIAS VALENTINE FERGUSON of 22 Sugar Island Newry, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in respirators, and has for its object to
provide an apparatus which is concealed in a garment having preferably the form
of a double cape and through which heated, screened, purifyed or medicated air
can be supplied to the wearer's mouth while due provision is made for the escape
of the exhaled air, the whole arrangement. having when applied to a person, the
appearance of an ordinary cape. the collar of which is tied over the mouth.
In carrying my invention into practice, I provide a double cape that is to say
an inner cape to which the respirator and its appendages are attached, and an
outer cape for external appearance. Inside the top of the cape or collar is
attached the respirator proper consisting of a mouth piece fitting tightly over the
mouth and nose of the wearer and provided with an inhaling and exhaling opening
both furnished with valves opening the first upward and the other downward, these
openings being furnished respectively with two pipes, the first of which leads to a
receptacle covered with fine wire coated with flannel to retain the solid particles,
moisture and the like, which may be held in suspension in the air, and containing
either dessicating or medicating substances. This first pipe is terminated with a
button shaped opening or mouth, and hangs loosely between the two capes, while
the second pipe i.e. the exhaling pipe is terminated in a similar manner as the
above or inhaling pipe, and hangs by the side thereof. The receptacle aforesaid
is fixed to a band or belt fastened around the wearers waist.
As my improvements are capable of some modifications without departing from
the principle thereof, I do not restrict myself to materials or dimensions, or to the
precise form or placement of the several parts thereof.

COMPLETE SPECIFICATION.
Improvements in and relating to Respirators.
I, MATHIAS VALENTINE FERGUSON of 22 Sugar Island Newry 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 improvements in respirators, and has for its object to
provide an apparatus which is concealed in a garment having preferably the form
of a double cape and through which heated, screened purified or medicated air can
be supplied to the wearer's mouth while due provision is made for the escape of
the exhaled air, the whole arrangement having when applied to a person, the
appearance of an ordinary cape, the collar of which is tied over the mouth.
In carrying any invention into practice, I provide a double cape that is to say
an inner cape to which the respirator and its appendages are attached and an quter
cape for external appearance. Inside the top of the cape or collar is attached the
respirator proper consisting of a mouth piece fitting tightly over the mouth and
nose of the wearer, and provided with an inhaling and exhaling opening both
furnished with valves opening the first upward and the other downward, these open-
ings being furnished respectively with two pipes the first of which leads to a receptacle
го.

page_text: covered with fine wire coated with flannel to retain the solid particles, moistures,
and the like which may be held in suspension in the air, and containing either
dessicating or medicating substances. This first pipe is terminated with a button
shaped opening or mouth and hangs loosely between the two capes, while the
second pipe i.e., the exhaling pipe is terminated in a similar manner as the above
or inhaling pipe, and hangs by the side thereof. The receptacle aforesaid is fixed
to a band or belt fastened around the wearer's waist.
In the accompanying drawings
Figs. 1 and 2 are views illustrating the application of my improved cape and
respirator to a figure, being respectively a side elevation with the corner of the
outer cape turned up and a front elevation with a portion of the outer cape
removed to show the respirator,
Fig. 3 is a section of the respirator proper and
Fig. 4 shows the position of the respirator in the cape.
My improved apparatus consists of the respirator proper a, which is of ordinary
shape and is provided at its lower part with two tubular projections or valve
chambers, inserted in the upper ends of the inhalation tube band exhalation
tube e respectively. The valve d in the chamber v opens upwardly whereas the
valve e in the chamber v¹ opens downwardly as shown in dotted lines in Fig. 3
respectively.
This respirator is sewn in the collar f of a garment composed of an inner
cape C and of an outer cape C (Figs. 1 and 2) both of which are joined to the
collar at the top and conceal the whole apparatus when the said collar is raised in
the position shewn in Fig. 1. The inhalation tube leads to a receptacle g
covered on one side with fine wire, coated with leather and containing any suit-
able dessicating or medicated substance, while the exhalation pipe c hangs loosely
by the side of the other tube and against the inner cape. The receptacle g is
fixed in any suitable manner to the belt i.
When the wearer draws an inspiration the valve d opens and admits air from
the outside after it has passed through the receptacle g, but when he exhales, the
valve d is closed and the valve e opened to allow for the discharge of the air
expired.
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
(1) The combination of a respirator with a garment for the purpose of
unostensibly administering dessicated or medicated air to a patient substantially
as herein described and shown.
(2) In a respirator the arrangement of two chambers containing an inspiration
and an expiration valve opening in reverse directions for the purpose of alternately
supplying dessicated or medicated air to a patient and allowing for the discharge
of the expired air substantially as herein described and shown.
