Improvements in the Manufacture of Waterproof Garments.
We, LOUIS FRANKENSTEIN of the Firm of P. Frankenstein & Sons,
Waterproof Manufacturers and DAVID BOCK Manager, of Millar Street,
Manchester in the County of Lancaster do hereby declare the nature of the said
invention to be as follows:-
This invention is designed to provide efficient ventilation for waterproof coats
and other garments.
Down the back of the coat between the shoulders or in other convenient position
the cloth from which the coat is made is provided with a number of perforations or
holes of any convenient size or with one or more slits or other openings. These
perforations or openings are preferably placed in a couple of rows extending from
the neck to the waist or nearly so.
On the outside of the coat over these perforations or openings over each row we
place a strip of cloth cemented or stitched along its edge forming two strips down
the back resembling the pleats or folds on the back of a Norfolk jacket. These
strips form channels or air ducts open top and bottom over the perforations or
openings through which warm or heated air from the interior may be allowed to
escape and cool or fresh air can pass through from the outside.
Rubber rings or the like may be inserted in the top and bottom ends of the
channels thus formed to prevent their closing and rubber or other buttons or strips
may be inserted at intervals therein to keep them distended. The open ends of
these channels are covered or hid from sight at the top by the collar of the coat
and if desired at the bottom by a belt or half belt flap button or other device
attached to the coat.
If desired similar perforations and strips may also be applied to the fronts or
other parts of the coat or garment.
Inside the coat at the back between the shoulders (or in other parts where it is
desired to ventilate the coat) we line it with a porous material such as flannel
through which air can pass covering the perforations or openings made in the cloth
to allow the free passage of air through the perforations or openings. This lining is
preferably loose and separated from the proofed cloth by strips of rubber cord or
the like thereby forming a series of air chambers between the lining and the cloth
in the back of the coat. If desired however the lining may be dispensed with.
Under the arms we prefer to insert pieces of unproofed cloth.

Improvements in the Manufacture of Waterproof Garments.
We, LOUIS FRANKENSTEIN, of the Firm of P. Frankenstein & Sons,
Waterproof Manufacturers, and DAVID BOCK, Manager, of Miller Street,
Manchester, in the County of Lancaster, 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 :-
This invention is designed to provide efficient ventilation for waterproof coats
and other garments.
It consists essentially in constructing the coat or garment with a number of
perforations or slits cut through the waterproof material down the back and
covering same on the outside with a strip of waterproof cloth attached at the edge
to form air ducts or channels and on the inside with a piece or strip of porous
material to allow the heated air to pass from the inside to the outside.
The invention will be fully described with. reference to the accompanying
drawings in which it is shown applied to a coat.
Fig. 1. Outside view from back.
Fig. 2. Inside view from front.
Fig. 3. Back view with the strips B removed.
Fig. 4. Inside view with the piece E of porous material removed.
Fig. 5. Sectional plan.
The coat A is made of waterproof cloth proofed with rubber or other material
in any ordinary way.
Down the back of the coat A between the shoulders or in other convenient
position the proofed cloth from which the coat is made is provided with a number
of perforations or holes a of any convenient size or with one or more slits or other
openings. These perforations or openings are preferably placed in a couple of
rows extending from the neck to the waist or nearly so.
On the outside of the coat to cover the perforations or openings a over each row
we place a strip of cloth B cemented or stitched along its edge forming two stripes
down the back resembling the pleats or folds on the back of a Norfolk jacket.
The strips B thus attached form channels or air ducts 6 open top and bottom
over the perforations or openings through which warm or heated air from the
interior may be allowed to escape and cool or fresh air can pass through from the
outside.
Rubber rings C or the like may be inserted in the top and bottoin ends of the
channels thus formed to prevent their closing and if desired rubber or other
buttons or strips may be inserted at intervals therein to keep them distended.
The open ends of the channels 6 are covered or hid from sight at the top by the
collar of the coat and by a small lid or cover D to prevent water running into them
and if desired at the bottom by a belt or half belt, flap button or other device
attached to the coat.
If desired similar perforations and strips may also be applied under the arms to
the fronts or other parts of the coat or garment.
Inside the coat A at the back between the shoulders (or in other parts where it
is desired to ventilate the coat) we line it with a piece or strip E of porous material
such as flannel through which air can pass covering the perforations or openings a
made in the cloth to allow the free passage of air through the perforations or
openings. This lining is preferably loose and separated from the proofed cloth by
strips of rubber cord or the like thereby forming a series of air chambers between
the lining and the cloth in the back of the coat. If desired however the lining
may be dispensed with.
Under the arms we prefer to insert pieces of unproofed cloth or holes such as a'.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A waterproof coat or garment constructed with a number of perforations (or
one or more slits or openings) cut in the proofed material covered on the outside
with strips of proofed material to form air ducts and covered or lined on the
inside with a porous material to allow of the free passage of air substantially as
described.
2. An improved waterproof coat or garment ventilated in the manner substantially
as described and shown.
