Captain from the Royal Navy. "IMPROVEMENTS IN THE MANUFACTURE OF HATS,

CAPABLE OF SUPPORTING PERSONS IN THE WATER."
For this purpose I line the hat, cap, or head gear with a thin bag of india-rubber
or other suitable material attached to the sides or crown, and I place a valve in the
hat or cap or in the india-rubber bag. When required for supporting a person in
the water, the hat, cap, or other head gear and the air bag, are filled with air, and
the valve closed; thus forming a life buoy.

FREDERIC PELHAM WARREN,, of Southsea, in the County of Hants, a Retired
Captain in the Royal Navy. IMPROVEMENTS IN THE MANUFACTURE OF HATS,
CAPS, AND OTHER HEAD GEAR OF BOTH SEXES, BY WHICH THEY CAN BE MADE
CAPABLE OF SUPPORTING PERSONS IN THE WATER."
This Invention has for its object improvements in the manufa cture of hats, caps,
and other head gear of both sexes, by which they can be made capable of supporting
persons in the water.
For this purpose. I line the hat, cap, or head gear with a thin bag of india-rubber
or other suitable material attached to the sides or crown, and I place a valve in the
hat or cap.
When required for supporting a person in the water, the hat, cap, or
other head gear and the air bag are filled with air, and the valve closed, thus forming
a life buoy.
Having stated so far the nature of my improvements, I now describe the valve
for inflating the life preserver.
This improved valve is made as shown in Figs. 1, 2, and 3 of the Drawings hereto
annexed.
Fig. 1 shows the valve in section, a representing the outer shell with cuttings b,
on which to fix the life preserver; d, the valve; e, the rubber or leather facing on
valve; f, the mouth-piece; g, the spiral spring.
When the valve is to be fixed in a hat it has a screwed washer h, with a male
thread or shell a for holding it in its place.
Fig. 2 represents plan of valve.
Fig. 3 represents the life preserver with valve attached.
It will be evident from this arrangement that the life preserver can be readily
inflated by pressing the mouth against the mouth-piece f, thereby opening the
valve d, which will admit of the life preserver being inflated, and on releasing the
pressure the valve is closed by action of spiral spring and pressure of air in life
preserver.
This valve can also be used for inflating air-beds, cushions, and other life
preservers.
Having now described the nature of my improvements, and the manner of carrying
the same into practice, I would have it understood that I claim,-
1st. The mode of attaching a lite preserver in a hat, cap, or other head gear of
both sexes.
2nd. The construction and arrangement of a valve, as substantially described, and
shown in the Drawing hereto affixed.
In witness whereof, I, the said Frederic Pelham Warren, have hereunto set my
hand and seal, this Nineteenth day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
FREDERIC PELHAM WARREN. (L.S.)
