IMPROVEMENTS IN VENTILATING HATS
Year: 1884

page_text: I. HENRY CHARLES ZERFFI of the firm of Macqueen and Company of 14
and 15 Long Lane, Aldersgate Street in the City of London, Hat Manufacturer
do hereby declare the nature of the said Invention for IMPROVEMENTS IN
VENTILATING HATS to be as follows:-
The invention relates to improvements in ventilating hats whereby air is
admitted to the interior of the hat whilst dust is excluded.
For this purpose I dispense with the eyelets ordinarily employed and make any
suitable number of holes in the body of the hat in any desired position and when
necessary the lining opposite such holes is cut away or perforated so as to avoid
interference with the incoming of the air.
On the exterior or on the interior of the hat covering, or in some cases on both,
I place over the holes in the hat body any suitable material which will act as a
filtering medium for the air.
Supposing the ventilating holes to be formed at a short distance above the brim,
I cover such holes by the hat band and sometimes between the body of the hat
and the lining, I place medicated wool or other suitable air filtering medium.
When the ventilating holes are made in other parts of the hat body I apply the
filtering medium only on the inside of the body. I also according to my invention
make each of the ventilating holes in the shape of a long and narrow aperture
running parallel with the brim of the hat such long narrow holes being in some
cases about two inches long and one quarter inch broad, but other dimensions and
shapes of holes inay be employed.
In hats having an under body covered with silk or other covering material I
form the holes in the under body and cover the same with the covering material
which will in some cases act as the filtering medium alone whilst in other cases
there may also be employed a filtering medium as before described on the interior
of the hat.

page_text: I HENRY CHARLES ZERFFI of the firm of Macqueen and Company of 14
and 15 Long Lane, Aldersgate Street, in the City of London, Hat Manufacturer
do hereby declare the nature of my Invention for IMPROVEMENTS IN VENTILATING
HATS, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The invention relates to improvements in ventilating hats whereby air is
admitted to the interior of the hat whilst dust is excluded. For this purpose I
make any suitable number of holes in the body of the hat in any desired position
and when necessary the lining opposite such holes is cut away or perforated so as
to avoid interference with the incoming of the air. On the exterior or on the
interior of the hat covering or in some cases on both I place over the holes in the
hat body any suitable material which will act as a filtering medium for the air.
Supposing the ventilating holes to be formed at a short distance above the brim.
I cover such holes by the hat band and sometimes between the body of the hat
and the lining I place medicated wool or other suitable air filtering medium.
When the ventilating holes are made in other parts of the hat body I apply the
filtering medium only on the inside of the body. I also according to my invention
make each of the ventilating holes in the shape of a long and narrow aperture
running parallel with the brim of the hat such long narrow holes being in some
cases about two inches long and 1½ inch broad but other dimensions and shapes of
holes may be employed.
+
In hats having an under body covered with silk or other covering material I
form the holes in the under body and cover the same with the covering material
which will in some cases act as the filtering medium alone whilst in other cases
there may also be employed a filtering medium as before described on the interior
of the hat.
My invention is represented in the accompanying drawings in which like parts
are marked with similar letters of reference.
Figures 1 and 2 represent respectively a vertical and horizontal section of a silk
or felt covered hat in the body a of which are formed ventilating holes b which are
covered on the exterior by the silk or felt covering c and also by the hat band d
whilst the leather lining e is perforated at e¹ as shown in the drawing or in other
suitable manner for the passage of the filtered air.
In this hat the air admitted through the holes b, is previously filtered by passing
through the band d and silk covering c whilst it passes into the interior of the hat
through the openings e¹.
In some cases I cut the holes b through both the body a and the silk or felt
covering c, in which case I place a piece of flannel or other suitable filtering
material between the body a and the leather lining e in addition to causing the air
to pass through the band d before entering the holes b or in some cases I form the
band d of material sufficiently closely woven to act as a filtering material.
Figures 3 and 4 are respectively an interior view and a vertical section of parts
of a felt hat in which the ventilating holes bare formed long and narrow as in
Figures 1 and 2 and the said holes are concealed by the band d whilst a band of
Thus
filtering material fis placed between the body a and the leather lining e.
the air has to pass through the band d, holes b, filtering band f and holes e¹, before
passing to the interior of the hat.
Figures 5 and 6 are respectively an interior view and a vertical section of that
form of hat known as a helmet in wbich the band d acts to conceal the holes b and

page_text: at the same time to filter the air passing into the hat through the holes b whilst
the air admitted through such holes passes up into the upper part of the hat or
helmet through the space between the body a and the leather lining e.
Figures 7 and 8 are respectively an interior view and a vertical section of that
form of hat known as a helmet in which the filtration of the air through the
holes bis obtained through an ornamental covering or puggaree g, in which case
the ventilating holes bare formed higher up the body a and the air admitted
through such holes b passes directly into the upper part of the hat or helmet.
In some cases when employing a filtering band f between the body a and the
leather lining e I form such band of medicated material or I apply suitable
antiseptics thereto.
The ventilating holes b may be of other shape than those shown in the drawings
and if desired they may be protected by eyelets but such is neither required nor
advisable and I would here remark that my invention is equally applicable to hats
and helmets of other materials and shapes than those herein shown and described.
Having thus described the nature of my said invention, and the mode in which
I carry the same into effect, I would have it understood that what I claim is
First constructing hats with ventilating holes 6 concealed by the silk or felt
covering c, band d, or covering g, the air passing through the holes b being filtered
by the silk or felt covering c band & filtering band for covering g or conjointly by
two or more of such parts whilst the air is caused to pass to the interior of the bat
or helmet through holes e¹, in the leather 6 or upwards between the leather lining e
and the body a or directly into the body a substantially as herein shown and
described and Second I claim filtering the air admitted to a hat in manner
substantially as herein shown and described.
