PROVISIONAL SPECIFICATION.
Improved Method of Fastening for Oilskin or Waterproof Coats, and
Fasteners for the same.
I, ALEXANDER DEL GUERRA of 160 Bute Street, Cardiff in the County of
Glamorgan Oilskin Manufacturer do hereby declare the nature of this invention to
be as follows:-
-:
In order to carry out my invention to the one flap or edge of the oilskin or
waterproof coat I fasten at suitable distances bodies made of metal or other suitable
substance shaped very like an ordinary collar stud with a rounded head, a stem or
shank of suitable length and a flange or base pierced with holes by which it can
be sewn to the coat, this piece I hereinafter call the stud. At corresponding
positions upon the other flap or edge of the oilskin or waterproof I fasten bodies
made substantially in one of the following methods. In the one method I take an
ordinary cap shaped stamping with holes pierced in its rim or edge to allow of its
being fastened to the garment and this stamping I hereinafter call the cap. Through
the centre of this cap I pierce a hole large enough to permit of the head of the
beforementioned stud to pass through it then inside the cap I insert either a piece
of indiarubber with a hole cut in it smaller than the head of the stud but slightly
Jarger than the shank, the hole in the indiarubber being concentric with the hole
in the cap, or I insert in the cap a circular coil of steel or other elastic body having
a hole in the centre smaller than the head of the stud, but slightly larger than the
shank. I then fasten the indiarubber or circular coil in the cap in any suitable
-
manner.
In the other method I take the same shaped stud and cap as before, but in the
cap I place a compound ring made substantially as follows, I take two half rings
having the semicircular hole inside smaller than the head of the stud, but larger
than the shank of the stud, and in the periphery of the half ring I cut a groove of
suitable depth so that when the two half rings are brought together. I can pass
around the ring thus formed and lying in the groove beforementioned a ring or
band of indiarubber or other suitable elastic body, the compound ring thus formed
I place inside the cap so that the hole in the ring is concentric with the hole in the
cap, this ring I hold in position in any suitable manner.
The action of the fastening is substantially as follows: On pressing the head of
the stud through the hole in the cap it forces open or expands the hole in the
indiarubber, spiral coil or compound ring placed in the cap and after passing
through this hole is held by the elasticity of the material surrounding the hole,
when it is desired to release the fastening all that is required is to give the stud a
sharp oblique pull.
I do not confine myself to any particular shape of the cap or stud.

I, ALEXANDER DEL GUERRA of 160 Bute Road Cardiff in the County of
Glamorgan, Oilskin 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 :-
The object of my invention is to provide fastenings for oilskin or waterproof

page_text: coats which can be fastened and unfastened with great ease.
In order to carry out
my invention, to the one flap or edge of the coat I fasten at suitable distances
bodies made of metal or other suitable substance shaped very like an ordinary
collar stud with a rounded or pearshaped head, five sixteenths of an inch in diameter
is a good size for this head, a stem or shank three sixteenths of an inch in diameter
and about the same length is a suitable size and a flange or base pierced with holes
by which it can be sewn to the coat, this piece I call the stud. At corresponding
positions on the other flap or edge of the coat I fasten bodies made substantially
as follows, I take an ordinary cap shaped stamping, about one inch in diameter,
one quarter of an inch deep and with a rim or flange round it about one-eighth of
an inch in width, this stamping I call the cap. In the centre of the cap I
pierce a hole about three-eighths of an inch in diameter, and in the rim or flange
pierce a number of small holes by which to sew the cap to the coat, then inside
the cap I place a compound ring made substantially as follows, I take a circular
washer or ring of any suitable substance, brass I prefer, this ring I make about
three quarters of an inch in diameter and one quarter of an inch in thickness, in
the centre of this ring I make a hole about five sixteenths of an inch in diameter
and on one side of the ring I countersink this hole until there only remains about
one sixteenth of an inch of metal, in the periphery of the ring I make a groove
about one thirty second of an inch in depth, this ring I then cut in two and pass
around it an elastic band preferably of indiarubber of such a thickness that whilst
the two halves of the cut ring are held together by the elastic band, the compound
ring thus formed of the two half rings and the elastic band just fills the cap, on the
back of the cap I fix a flat plate of brass or other suitable substance with a hole
about three sixteenths of an inch in diameter pierced in its centre, this plate being
to hold the compound ring in the cap. I do not confine myself to the sizes given
above but mention them as good working sizes and to make my method clear.
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
The combination of stud, cap and compound ring made and fixed substantially
as described above for the purpose of providing fastenings for oilskin or water
proof coats.
