page_text: LETTERS PATENT to Bennett Johns Heywood, of Hawley Road, Camden
Town, in the County of Middlesex, Gentleman, for the Invention of
"IMPROVEMENTS IN VALVES FOR INFLATING AIR-TIGHT BAGS, CUSHIONS, AND
OTHER SIMILAR ARTICLES. AND FOR DRAWING OFF LIQUIDS."
Sealed the 14th April 1857, and dated the 15th October 1856.
PROVISIONAL SPECIFICATION left by the said Bennett Johns Heywood
at the Office of the Commissioners of Patents, with his Petition, on the
15th October 1856.
I, BENNETT JOHNS HEYWOOD, of Hawley Road, Camden Town, in the
County of Middlesex, Gentleman, do hereby declare the nature of the Inven-
tion for "IMPROVEMENTS IN VALVES FOR INFLATING AIR-TIGHT BAGS, CUSHIONS,
AND OTHER SIMILAR ARTICLES, AND FOR DRAWING OFF LIQUIDS," to be as
follows:-
This Invention consists in arranging valves for inflating bags, cushions, and
other similar articles, and for drawing off liquids in the following manner:―
Into the mouth of the bag or other article a socket is fitted, having a screw
on its interior. In the centre of the bottom of this socket is a hole, and round
the hole a conical enlargement, which fits into a similar depression in the plug
which screws in the socket, and round this conical depression in the plug a
series of holes are bored in an inclined direction, so as to lead into a single

page_text: hole in the top of the plug. When it is wished to inflate the bag, the plug
is turned round so as to raise it from the cone at the bottom of the socket, and
air is (by the mouth or otherwise) forced into the hole at the top of the plug,
and to close the communication with the bag the plug is screwed down on to
the cone in the socket.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Bennett Johns Heywood in the Great Seal Patent Office on
the 15th April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENNETT
JOBNS HEYWOOD, of Hawley Road, Camden Town, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Bennett Johns Heywood, Her special license that I, the said Bennett
Johns Heywood, my executors, administrators, and assigns, or such others as
I, the said Bennett Johns Heywood, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN VALVES FOR INFLATING AIR-TIGHT BAGS, CUSHIONS, AND OTHER
SIMILAR ARTICLES, AND FOR DRAWING OFF LIQUIDS," upon the condition (amongst
others) that I, the said Bennett Johns Heywood, my executors or adminis-
trators, by an instrument in writing under my, their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
-
NOW KNOW YE, that I, the said Bennett Johns Heywood, do hereby
declare the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the follow-
ing statement thereof, that is to say:-
This Invention consists in arranging valves for inflating bags, cushions, and
other similar articles, and for drawing off liquids in the following manner :-

page_text: Into the mouth of the bag or other article a socket is fitted, having a screw
on its interior. In the centre of the bottom of this socket is a hole, and round
the hole a conical enlargement which fits into a similar depression in the plug
which screws into the socket, and round this conical depression in the plug a
series of holes are bored in an inclined direction so as to lead into a single
hole in the top of the plug. When it is wished to inflate the bag, the plug
is turned round so as to raise it from the cone at the bottom of the socket, and
air is (by the mouth or otherwise) forced into the hole at the top of the plug;
and to close the communication with the bag, the plug is screwed down on to
the cone in the socket. The valve is in a similar manner applied for drawing
off liquids.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a vertical section, and Figure 2 a side view, of a valve con-
structed according to my Invention, and arranged for inflating an air-tight
bag, a cushion, or other similar article. a, a, is part of the fabric of the bag,
into the mouth of which the socket 6 (shown in plan in Figure 8) is fixed by
means of the nut c screwing on to the stem of the socket, and nipping the
fabric between its upper side and the under side of the socket. Up through
the stem of the socket is a hole or passage 6' surrounded at its upper end
where it enters the socket by a conical enlargement. d is a plug which screws
into the socket b; it has on its under side a conical indentation corresponding
with the enlargement in the socket, and when the plug is screwed down these
parts are brought together, and an air-tight joint is made, but when this is
partially unscrewed air can be blown into the bag, cushion, or other article,
the mouth being applied to the upper part of the plug, and the air passes
through the passage in the centre of the plug, and then by the inclined
holes into the socket 6, from whence it passes into the bag, cushion, or other
article by the passage b¹.
Figures 5 shew similar views of a valve adapted for stopping a baby's
Bucking bottle; by partially unscrewing the plug a passage is opened, by which
air can enter the bottle, and this enables the infant to draw the liquid out of
the bottle by sucking at the nipple.
Figures 6 shew similar views of a valve adapted to the vent peg of a beer
cask. The construction of this valve will be readily understood from the
Drawing, without any detailed description.

page_text: Figures 7 show similar views of a valve suitable for cementing on the mouth
of a bottle, for containing beverages, which can be extracted from the bottle
by sucking at the end of the plug when it is partially unscrewed.
Figures 8 show similar views of a valve adapted for closing the end of a
hollow walking stick, which may then be used for carrying liquids for refresh-
ment while walking. The liquid is extracted by sucking the end of the stick
when partially unserewed. This arrangement will easily be understood by
reference to the Drawing without any detailed description.
In witness whereof, I, the said Bennett Johns Heywood, have hereunto
set my hand and seal, this Fifteenth day of April, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
S. CARPMAEL.
