PROVISIONAL SPECIFICATION.
An Improved Eyelet Ventilator for Hats and Caps.
We, WILLIAM WALLIS TWIGG, of 133 Great Charles Street, in the City of
Birmingham, Manufacturer, and JOHN GEE NORMAN, of 133, Great Charles
Street, aforesaid, Manufacturer's Manager, do hereby declare the nature of this
invention to be as follows: -
This invention consists of the hereindescribed improved eyelet ventilator for hats
and caps.
Our said improved ventilator is one of that kind which consists essen-
tially of two metal eyelet like parts which fit together in a hole in the top of the
hat or cap and embrace the fabric of the hat or cap between their flanges the
central hole of one of the said eyelet like parts being covered by fine wire gauze or
other perforated material.
In our said improved ventilator that portion of the inner eyelet (that is the
eyelet which fits within the other eyelet part) is made very slightly bellmouthed and
has one or more slots or divisions (say four divisions but we do not confine ourselves
to any particular number) and the outer eyelet like part is also made slightly bell
mouthed and enlarged in diameter where the bellmouthed part joins the flange so
that when the said inner eyelet is placed within the bell mouth of the outer eyelet
part and the two parts are pressed together the bell mouth of the outer part first
acts upon and forces the divided portions of the inner eyelet together (the slots or
divisions allowing of this) and then the divided portions spring outwardly again and
engaging with the enlarged part of the outer eyelet the two eyelet parts of the
ventilator are secured together. The two eyelet parts can readily be separated
from each other by an outward pressure on the flanges as in other eyelet
ventilators.

COMPLETE SPECIFICATION.
An Improved Eyelet Ventilator for Hats and Caps.
We, WILLIAM WALLIS TWIGG, of 133 Great Charles Street, in the City of
Birmingham, Manufacturer, and JOHN GEE NORMAN, of 133, Great Charles
Street, aforesaid, Manufacturer's Manager, 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 consists of the hereindescribed improved eyelet ventilator for hats
and caps. Our said improved ventilator is one of that kind which consists essen-
tially of two metal eyelet like parts which fit together in a hole in the top of the
hat or cap and embrace the fabric of the hat or cap between their flanges the
central hole of one of the said eyelet like parts being covered by fine wire gauze or
other perforated material.
In our said improved ventilator that portion of the inner eyelet (that is the
eyelet which fits within the other eyelet part) is made very slightly bellmouthed
and has one or more slots or divisions (say four divisions but we do not confine
ourselves to any particular number) and the outer eyelet like part is also made

page_text: slightly bellmouthed and enlarged in diameter where the bellmouthed part joins
the flanges so that when the said inner eyelet is placed within the bell mouth of the
outer eyelet part and the two parts are pressed together the bell mouth of the outer
part first acts upon and forces the divided portions of the inner eyelet together (the
slots or divisions allowing of this) and then the divided portions spring outwardly
again and engaging with the enlarged part of the outer eyelet the two eyelet parts
of the ventilator are secured together. The two eyelet parts can readily be separated
from each other by an outward pressure on the flanges as in other eyelet
ventilators.
The accompanying drawings illustrate on an enlarged scale an eyelet ventilator
constructed according to this invention, the said ventilator being shewn in sectional
elevation and in plan by Figures 1 and 2 respectively;
Figure 3 is a plan and elevation of the inner eyelet part of the same; and,
Figure 4 is a sectional elevation and plan of the outer eyelet part of the same.
A is the inner eyelet part of the ventilator which as shewn we make very
slightly bellmouthed at a' and with one or more, preferably four, divisions marked
respectively a as a as thus dividing the bellmouthed part into separate portions in
this case four in number marked respectively a a7 as a separated from each other
but all integral with the flanged portion a10. B is the outer eyelet like part of the
ventilator which is covered by a disc b of fine wire gauze or other perforated
material enclosed in the flanged portion 63 in the usual way. This eyelet portion B
is made slightly bellmouthed at 61 and enlarged in diameter at 62 where the bell-
mouthed part joins the flange 63 so that when the bellmouthed part a' of the inner
eyelet is placed within the bellmouth 6 of the outer eyelet part and the two parts
are pressed together, the bellmouth b¹ will first act upon and force the divided
portions of the inner eyelet A together, (the slots or divisions a² a³ a* a³ allowing of
this) and then the divided portions will very slightly spring outwardly again and
engage with the enlarged part 2 of the outer eyelet B as shewn in Fig. 1 and the
two parts A B of the ventilator will be secured together.
To separate the part A. from the part B it is only necessary to press their
flanges outwardly so as to disengage them from each other.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improved eyelet ventilator for hats and caps hereinbefore described and
illustrated by the accompanying drawings, consisting in the combination with the
outer bellmouthed eyelet part B of the inner eyelet part A having its portion
which fits in the eyelet B divided and shaped substantially as hereinbefore set forth
so as to engage with the outer eyelet part A in the manner described and shewn
when the two parts of the eyelet ventilator are pressed together.
2. Making the inner eyelet part of an eyelet ventilator of the kind herein
referred to for hats and caps with one or more longitudinal slots or divisions
substantially as described so as to enable said inner eyelet part to engage with the
outer eyelet part in the manner substantially as described and shewn.
