AN IMPROVE- MENT OR IMPROVEMENTS IN PIPES POR SMOKING
Year: 1867

page_text: LETTERS PATENT to Edward John Padbury, of Birmingham, in the
County of Warwick, Lithographer, for the Invention of "AN IMPROVE-
MENT OR IMPROVEMENTS IN PIPES POR SMOKING."
Sealed the 30th July 1867, and dated the 31st January 1867.
PROVISIONAL SPECIFICATION left by the said Edward John Padbury
at the Office of the Commissioners of Patents, with his Petition, on the
81st January 1867.
I, EDWARD JOHN PADBURY, of Birmingham, in the County of Warwick,
Lithographer, do hereby declare the nature of the said Invention for "AN
IMPROVEMENT OR IMPROVEMENTS IN PIPES FOR SMOKING," to be as follows:-
My Invention consists of a perforated metallic disk or diaphragm, or a
framework of fine metallic bars supported or fixed in the bowl of a pipe, as
herein-after explained, for the purpose of supporting the tobacco in the bowl,
and keeping the hole in the stem of the pipe free from the obstruction which
occurs in pipes charged with tobacco in' the ordinary way. I make the said,
metallic disk or diaphragm by preference of sheet metal cut out and perforated
with a series of small holes in a press. In order to support the perforated
disk at a short distance above the bottom of the pipe bowl I attach to the
edge of the disk two or more arms or wires, the said arms being nearly parallel

page_text: and at right angles to the plane of the disk; one of these arms is longer
than the others and is curved at top; the said top end turns over the edge of
the pipe and serves as a handle by which the disk or diaphragm may be
removed. The said arms by their elasticity press against the inside of the
pipe, and thereby hold the disk securely in its position. These arms may
either be made separate from the disk and affixed thereto by soldering or
revetting, or they may be made in one piece with the disk by being cut
out with the disk by means of properly shaped press tools. Instead of a
disk of perforated sheet metal a frame of thin metallic bars may be employed.
In this way of carrying my Invention into effect I employ wire gauze, from
which I cut circular disks and attach thereto by soldering or otherwise wire
arms for the purpose of supporting the disk in the lower part of the bowl of
the pipe.
The disk or diaphragm may be made of a cup-like form and slit at its sides:
to make it elastic and fix it in the pipe bowl.
By my Invention a more perfect draught and a more perfect combustion of
the tobacco are obtained than in ordinary pipes.
A gentle puff of air after the pipe has been smoked out effectually removes
the ash and cleans the pipe..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward John Padbury in the Great Seal Patent Office
on the 30th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
JOHN PADBURY, of Birmingham, in the County of Warwick, Lithographer,
send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of January, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for. Herself, Her heirs and successors, give and grant unto me, the said
Edward John Padbury, Her special licence that I, the said Edward John
Padbury, my executors, administrators, and assigns, or such others as I, the
said Edward John Padbury, my executors, administrators, and assigns, should
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 Chaunel Islands, and Isle of Man, an Invention for "AN
at

page_text: IMPROVEMENT OR IMPROVEMENTS IN PIPES FOR SMOKING," upon the condition
(amongst others) that I, the said Edward John Padbury, my executors or
administrators, by an instrument in writing under my, or 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 Edward John Padbury, do hereby
declare the nature of my said 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 an improvement or improvements in pipes for
smoking to consist of a metal dise (see Drawings, No. 1, elevation with
tassel attached, and No. 1º, plan) with a serrated or fringe edge to secure the
same in the pipe, No. 7 on Drawing representing section of pipe showing
position of ventilator and with ornamental stem or handle to facilitate removal,
and finely perforated to allow a free current of air or smoke to pass through,
but now to allow the tobacco or ashes to pass, thereby preventing the fouling
of the pipe or air passage. The article I therefore call a dust-preventing
ventilator or "fumador."
The essential difference between this Invention and all previous ones
consists in the fineness of the perforations (or meshes if wire gauze is used,
as shown on Drawing No. 5), whereby the tobacco dust is retained, while
the smoking is facilitated and the flavor of the tobacco much improved.
I further claim the Invention for making the article in part of cork or
wood (as shown on Drawing No. 4) and part metal; also in ceramic ware,
pressed, or baked, or cast composition or clay, as buttons and such like articles,
see Drawing No. 2, elevation, and No. 2, plan, and also for a small tassel
attached for the purpose of absorbing the oil.
Nos. 3 and 6 show modifications of my Invention.
In witness whereof, I, the said Edward John Padbury, have hereunto
set my hand and seal, this Twenty-ninth day of July, in the year of our
Lord One thousand eight hundred and sixty-seven.
EDWARD JOHN PADBURY. (L.S.)
