page_text: LETTERS PATENT to Lewis Fairburn Marsh, of 39 and 40, Castle Green, in
the City of Bristol, Hat Manufacturer, for the Invention of "IMPROVEMENTS
IN VENTILATING HATS AND CAPS."
led the 16th April 1878, and dated the 29th November 1877.
PROVISIONAL SPECIFICATION left by the said Lewis Fairburn Marsh
at the Office of the Commissioners of Patents on the 29th November 1877.
LEWIS FAIRBURN MARSH, of 39 and 40, Castle Green, in the City of Bristol, ITat
Manufacturer. "IMPROVEMENTS IN VENTILATING HATS AND CAPS."
In ventilating hats and caps apertures have been punched or otherwise formed in
the body near the brim, to admit atmospheric air to the inside, the heated air
escaping from an aperture in the top or crown.
Forming holes in the body, as above stated, enables rain water to flow in, and
causes inconveniences to the wearer.
My Invention consists in forming slits at the junction of the body and brim at
the forehead part, and in fitting flat tubes (metal or other material) within the hat
or cap, with the lower mouths of the tubes projecting or flush with the body as to
leave clear and free apertures under the silk or other band. The lower ends of the
flat tubes are curved, and the upper parts are secured and lie close to the body up
to about level with the top of the ")
"leather "f
or canvas round," for the free passage
of air into the interior of the hat or cap, from which the heated air may escape from
the crown in the usual manner.
">
I protect the lower mouths of the flat tubes, which might otherwise be unsightly,
by a silk or other band, in which the weavings at the lower portions are left more
open than usual to allow the air to pass through to the flat tubes.

by the said Lewis Fairburn Marsh in the Great Seal Patent Office on the
29th May 1878.
LEWIS FAIRBURN MARSH, of 39 and 40, Castle Green, in the City of Bristol, Hat
Manufacturer. " IMPROVEMENTS IN VENTILATING HATS AND CAPS."
In ventilating hats and caps, aportures have been punched or otherwise
formed in the body near the brim to admit atmospheric air to the inside, the heated
air escaping from an aperture in the top or crown.
Forming holes in the body, as above stated, allows rain water to flow in, and
causes inconveniences to the wearer.
My Invention consists, as will be clearly understood by reference to the annexed
Drawings, in forming slits a at the junction of the body and brim at the forehead,
back, or side parts of hat, preferably at forehead part b, and in fitting tubes c, c, c, c,
of metal or other material within the hat or cap, with the lower mouths of the
tubes projecting or flush with the body so as to leave clear and free apertures under
or through the silk or other band d. The lower ends of the tubes are curved, as
shown at and the upper parts are secured and lie close to the body up to about
level or otherwise with the top of the "leather" or "canvas round" for the free
passage of air into the interior of the hat or cap, from which the heated air will
escape through the crown at f in the usual manner.
1 protect the slits or lower mouths & of the tubes c, which might otherwise be
unsightly, by a silk or other band, expressly woven with a perforated edge, either
at the lower portion or otherwise, to allow the air to pass through to the tubes.
I am aware that hats have been formed with aportures in the band or side wall,
and with an annular space all round the body of the hat up to the top of the
leather or canvas "round," so as to form a space for the free passage of the air,
which is allowed to escape at the top, but my Invention, and that to which I lay
claim as my "Improvements in Ventilating Hats and Caps," consists in fitting flat,
oval, round, square, or other tubes (preferably metallic), and flat inside the body of
the hat, passing through the body to the outside for ventilating purposes, the hot
air being allowed to escape through the crown in the usual manner, as described,
and as shown in the accompanying Drawings.
In witness whereof, I, the said Lewis Fairburn Marsh, have hereunto set
my hand and seal, this Twenty-seventh day of May, One thousand eight
hundred and seventy-eight.
LEWIS FAIRBURN MARSH. (L.S.)
