PROVISIONAL SPECIFICATION.
Improvements in the Ventilation of Waterproof and like Garments.
We, FREDERIC GEORGE RICHARDSON, of 14, Norman Road, Birkby, Hudders-
field, in the County of York, Cutter and Designer, and HERBERT HARDCASTLE,
of 8, Norman Road, Birkby, Huddersfield, aforesaid, Plumber, do hereby declare
the nature of this invention to be as follows;
1
This invention relates to the method of and means for ventilating waterproof
garments and like rainproof clothing so as to allow for the free ingress and
egress of air when required.
Our improvements consist of a corrugated or fluted plate composed of plain
or perforated brass or gauze or other suitable metal or material of a sufficiently
stiff nature, the corrugations or obverse and reverse flutes or channels being
preferably at right angles to the length of the plate or they may be arranged at
any angle or crosswise, so as to give clear passages from one edge to the other
on both sides. The said plate is made to a convenient size and shape to fit the
particular parts of the garment to be ventilated which are commonly the arm-
pits and the under portions of the sleeve. An opening is made in the garment
at a point just above where the plate is to be applied and the latter is secured
by stitching or other means to a flap or overhanging backing on the inside of
the garment, and occupies a position between same and the said flap, the corruga-
tions or flutings at one end communicating with the slit or opening before named
and at the lower end being open to the inside of the garment.
By the means described a constant passage of air to and from the inside of the
waterproof obtained, and such ventilation cannot be stopped or impeded when
the arms are held close to the body, as is the case with the present method of
ventilation.

field, in the County of York, Cutter and Designer, and HERBERT HARDCASTLE,
of 8, Norman Road, Birkby, Huddersfield, aforesaid, Plumber, 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:-

hono toquired

page_text: Our improvements consist of a corrugated or fluted plate composed of plain
or perforated brass or gauze or other suitable metal or material of a sufficiently
stiff nature, the corrugations or obverse and reverse flutes or channels being
preferably at right angles to the length of the plate or they may be arranged at
any angle, or cross wise, so as to give clear passages from one edge to the other
on both sides. The said plate is made to a convenient size and shape to fit the
particular parts of the garment to be ventilated which are commonly the arm-
pits and the under portions of the sleeves. An opening is made in the garment
at a point just below or above where the plate is to be applied and the latter is secured
by stitching or other means to a flap or overhanging backing on the inside of
the garment and occupies a position between same and the said flap, the corruga-
tions or flutings at one end communicating with the slit or opening before named
and at the opposite end being open to the inside of the garment
By the means described a constant passage of air to and from within the
garment is obtained and such ventilation cannot be stopped or impeded when
the arms are held close to the body as is the case with the present method of
ventilation.
In order that our said invention may be fully understood reference is herein-
after had to the annexed drawings forming a part of this specification in
which:-
Fig. 1, represents the arm, shoulder, and neck portion of a waterproof or like
garment shewing the application of our improved ventilator thereto;
Fig. 2 is a transverse section of same on an enlarged scale;
Fig. 3 is enlarged geometrical view of our improved ventilator detached; and
Fig. 4 is a similar view to Fig. 3, shewing a modification.
e,
C
Referring to the drawings, letter a represents the waterproof garment under
the arm hole 6 of which is made a slit or opening c forming an inlet to and outlet
from the inside of the garment. On the back or inside of the fabric a and, over-
lapping or covering the opening or slit c is a flap or cover d preferably composed
of the same material as the garment in order that if the opening c be exposed to
view, the underclothing cannot be seen and only the outline of the opening will
shew. The flap d in the examples shewn, is solutioned or otherwise secured at
the lower edge and sides to the inner face of the fabric. a, and near the free. or
loose upper edge of said flap and a little above or just clear of the opening
is secured by stitches, rivets, or other suitable means, the ventilator which
comprises a piece of metal, or other stiff material suited to the purpose, having
corrugations or flutes e¹ formed at right angles to its length, as shewn; or at
any other suitable angle, or the adjacent flutes or corrugations may be formed at
opposite angles or cross wise of each other; these corrugations or flutes forming
from one longitudinal edge to the other on both sides of the metal strip, open
passages along which air can pass in either direction. The position of the
ventilator is thus intermediate of the garment a and flap d and consequently
prevents said parts from being pressed together and the opening c closed, there
always being the open spaces formed by the corrugations or flutes for the egress
of hot air from within the garment and the ingress of cold air to take its place.
By the said means an invisible ventilator is provided which is always open to the
free currency of air to and from within when the garment is worn, and which
cannot possibly be closed by the usual pressure of the arms against the body.
The said ventilator, unlike the ordinary eyeletted ventilators does not injure
or rub away the sleeves, and is not liable to drop out of its place, it is easily fixed
to new or existing garments, and adds little or no extra weight compared with
other ventilators.
The ventilator herein before described may also be applied to the under sides
of the sleeves of the garment if wanted, and to any other part of the garment
where it is desired to have free ventilation, the shape of the plate e being made
to suit the particular part to which it is to be applied.
In Fig. 4, we shew a modification of the ventilator e comprising perforations

page_text: or openings formed through the corrugations which abut against the garment
as shewn; or the metal of which the ventilator is made may be a perforated
metal or gauze, the perforations allowing air to enter in various directions.
Although we have described and shewn the ventilator e as being above the
opening or slit c, we would observe that it may be placed below said opening,
and the flap d reversed correspondingly the cold air from without entering in a
downward direction through the ventilator and the hot air from within the gar-
ment rising up through the ventilator to the opening c.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
(1). In waterproof or like garments, the combination of a slit or aperture such
as c, a flap or cover secured on three of its edges or sides to the inside of the
garment to cover or overlap said slit or aperture and a corrugated, fluted or like
strip of metal or other suitable material attached preferably to the flap near the
unsecured edge or side thereof and occupying a position between said flap and the
garment to maintain a clear thoroughfare there between and admit of the free
egress of hot air from within the garment and the ingress of cold air from without
substantially as herein shewn and described.
(2). The application to waterproof or like garments of a corrugated, fluted, or
like plate or strip of metal or other suitable material, to which air is admitted
through an opening or slit in the garment which is kept constantly open by
said plate, the same being applied and acting in the manner and for the purposes
substantially as herein set forth.
