Improvements in or relating to the Ventilation of Waterproof
Coats.
I, BARNETT ABRAHAMS, of 124 Bishopsgate Street Without, City of London,
Waterproof Clothing Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in or relating to the ventilation of
waterproof coats.
For the purpose of my invention, I make the upper back lining separate from
the outer or waterproof fabric from above the waist portion to the collar or collar
band, said looseness being also over the shoulders and well towards the upper
breast parts for ventilating purposes.
The lining is of coarsely woven fabric or of a fine fabric perforated with holes at
the parts where a film of waterproof solvent has been spread to give sufficient
rigidity and prevent tearing.
The shoulders and back portions of the lining fabric are secured at intervals to
the collar or collar band as a means of connecting one to the other. The two
fabrics may, if desired, be kept apart by films or thin slices or buttons of cork
cemented in place on either the outer or the inner fabric.
I make the armpit portions in the same manner and seam lappels or tabs to the
armpits the openings being in connection with the back or the front or with both
back and front portions of the non-attached fabrics.
The lappels or tabs have cork in them and in most cases the liner strips also to
keep the air passages clear.

COMPLETE SPECIFICATION.
Improvements in or relating to the Ventilation of Waterproof
Coats.
I, BARNETT ABRAHAMS, of 124 Bishopsgate Street Without, City of London,
Waterproof Clothing Manufacturer, 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 relates to improvements in the ventilation of waterproof coats.
For the purpose of my invention, I make the upper back lining separate from
the outer or waterproof fabric from above the waist portion to the collar or collar
band, said looseness being also over the shoulders and well towards the upper
breast parts for ventilating purposes. The lining is of coarsely woven fabric or of
a fine fabric perforated with holes at the parts where a film of waterproof solvent
has been spread to give sufficient rigidity and prevent tearing.

page_text: The shoulders and back portions of the lining fabric are secured at intervals to
the collar or collar band as a means of connecting one to the other. The two
fabrics may if desired be kept apart by films or thin slices or buttons of cork
cemented in place on either the outer or the inner fabric.

I make the armpit portions in the same manner and seam lappels or tabs to the
armpit, the openings being in connection with the back, or the front, or with both
back and front portions of the non-attached fabrics."
The lappels or tabs have cork in them and in most cases the liner strips also to
keep the air passages clear.
.
My invention is represented in the annexed drawings.
Figure 1 elevation of interior of a mackintosh or waterproof coat with inner
.lining.
Figure 2 exterior side elevation with sleeve thrown up to show armpit vents.
Figure 3 part side view with piece removed from outer ply of the sleeve to
indicate inside of under ply with arm vents.
Referring to Figure 1, A represents the inside of a waterproof coat in outline or
spread open flap. B the lining. C upper back with vent aperture said lining
being loose from the waist portion to the collar band seam D where it is attached
at places sufficient to allow heat and condensed vapour to pass away by the
looseness or slight baggyness of the lining back and shoulders. E, E, are other
vent apertures in the breast of the lining where there is also an amount of looseness
between the two fabrics for the escape of perspiration upward to the shoulder
portions. F, F, are vent apertures in the upper part of the sleeve lining, said
upper part being loose from the outer fabric in order that the space so formed may
also be in communication with the shoulder and collar seam outlets.
Referring to Figures 2 and 3 where instead of the apertures shown in the arm
portions of both sleeve and body I form slits G with under lapping patches or
tabs H and I keep the slits open by small bits of cork or other projecting
pieces I, 1, the openings leading up to the collar outlets for vent purposes.
I have in the foregoing referred to waterproof coats provided with linings but
the slits G with tabs H and cork bulging pieces I can be arranged in coats having
no linings i.e. coats made of a compound fabric without loose linings in which case
the depths of the tabs H will be sufficient to prevent rain-water percolating
through, and at the same time ensure perfect ventilation where most needed.
The cork or other bulging substance can be cemented on or in the fabric.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved method of preparing ventilating properties in waterproof coats
as herein before described and substantially as represented in the annexed
drawings.
2. The employment of loose upper lining with vent holes leading up to collar
band where the lining is affixed at parts only with waterproof coats as described
and substantially as shown.
3. Providing vent slits of waterproof coats with bulges of cork or other body
for keeping open the air passages of the armpit portions of body and of sleeve, or
either of them as described and substantially as represented in the annexed,
drawings.
