I, PETER CRUICKSHANK, India Rubber Worker, 10 Ardmillan Terrace, Edinburgh,
Scotland do bereby declare the nature of my invention for IMPROVEMENT IN THE
MAKE AND METHOD OF VENTILATING INDIA RUBBER WATERPROOF GARMENTS to
be as follows:-
The Garment is composed of two plies of Tweed or other material. For the
outer ply, no coating of rubber is used as is the custom ordinarily followed in
the case of Garments waterproofed with India rubber or a compound therof; the
Tweed or other material being in this instance left exactly as it comes from the
weaver, or treated after the manner usually adopted for rendering it, what is
known in the trade as shower proof cloth. The inner ply or lining which is also
of Tweed or other material is in the first place coated with India rubber or a
compound therof, so as to render it thoroughly waterproof. In this inner ply or
lining openings or apertures are formed and covered over with proofed cloth in such
a way, as while admitting a free passage for air, water is thoroughly excluded, and
the garment thereby, while being perfectly ventilated, is at the same time quite
waterproof.

I, PETER CRUICKSHANK, 10 Ardmillan Terrace, Edinburgh, in the county of
Midlothian, North Britain, Bookkeeper, do hereby declare the nature of my
invention for IMPROVEMENT IN THE MAKE & METHOD OF VENTILATING INDIA
RUBBER WATERPROOF GARMENTS and in what manner the same is to be performed,
to be particularly described and ascertained in by the following statement :-
The garment consists of two plies of tweed or other suitable material. For the
outer ply I use the fabric in its ordinary state, without previously coating it with
india rubber (the method usually adopted with waterproof garments). The various
sections of the outer ply, I prefer to join together by stitching but they may also
be fixed by using a solution of india rubber or any of the other known methods.
For the inner ply or lining I take a piece of fabric and have it rendered waterproof
by coating with india rubber or any of the known methods. The sections of the
inner ply may be joined together either by stitching, or by using a solution of
india rubber; if the former process is adopted, a narrow strip of proofed cloth is
placed over the stitches and firmly attached with a solution of india rubber, in the
same way as is presently adopted in waterproof garments with sewn seams. Το
secure ventilation apertures are formed in the inner ply, and the parts where they
are placed are strengthened by attaching, by any suitable means, a piece of any
strong porous material. These apertures I prefer to place in the upper part only,
but they may be carried through the entire ply. Over these apertures I put
coverings or lids of proofed cloth, sufficiently large to prevent the ingress of water,
and fix them firmly at upper edge and sides, with rubber solution, leaving them
open at bottom, thus forming a channel for the admission of air. The two plies
are then joined together by any suitable means, at seams and edges only, the
proofed ply forming the lining, and the unproofed ply forming the outer part.
The garment is then finished off by any of the methods well known to makers of
waterproof garments.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
I. The production of a ventilated waterproof garment possessing none of the
objectionable features (such as shoulder capes, cuts across the back &c) characteristic
of the present methods of ventilation.
II. The production of a waterproof garment, having an outer ply of unproof
cloth, wherby, the "stiffish" appearance of the rubber proofed garments presently
in use, is obviated.
