Year: 1871

page_text: LETTERS PATENT to Jacob Holdsworth, of Bradford, in the County of
York, Manufacturer, for the Invention of "AN IMPROVED FEED OR
SUPPLY PIPE FOR SUPPLYING ILLUMINATing Gas to Gas Burners.”
PROVISIONAL SPECIFICATION left by the said Jacob Holdsworth át
the Office of the Commissioners of Patents, with his Petition; on
the 18th October 1871.
I, JACOB HOLDSWORTH, of Bradford, in the County of York; Manu-
facturer, do hereby declare the nature of the said Invention for "AN
IMPROVED FEED OR SUPPLY PIPE FOR SUPPLYING ILLUMINATING GAS TO GAS
BURNERS," to be as follows:-
The object of this Invention is to prevent excess of pressure on the
burners and consequent waste of gas.
This I effect by the use of an internal tube inserted and secured
concentrically within the supply pipe at a point near the stop-cock.
The hole or bore of the internal tube is of very small diameter so as to
prevent excess of gas reaching the burner. Although from various
:

appliance greatly economises gas, especially where the number of lights
in use is varied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jacob Holdsworth in the Great Seal Patent |
Office on the 18th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACOB
HOLDSWORTH, of Bradford, in the County of York, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Jacob Holdsworth, Her special licenco
that I, the said Jacob Holdsworth, my executors, administrators, and
assigns, or such others as I, the said Jacob Holdsworth, 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
Eslands, and Isle of Man, an Invention for "AN IMPROVED FEED Or Supply
PIPE FOR SUPPLYIng Illuminating Gas To Gas BURNERS," upon the condition
(amongst others) that I, the said Jacob Holdsworth, 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 Scal
Patent Office within six calendar months next and immediately after
the date of tho said Letters Patent.
NOW KNOW YE, that I, the said Jacob Holdsworth, 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 and accompanying Sheet of Drawings (that is to
say):
The object of this Invention is to prevent excess of pressure on the
humous and consonant wants
-

page_text: This I effect by the use of an internal tube inserted and secured
concentrically within the supply pipe at a point near the stop-cock.
The hole or bore of the internal tube is of very small diameter so as to
prevent. excess of gas reaching the burner. Although from various
causes the pressure on the internal pipe varies I find the use of this
appliance greatly economises gas, especially where the number of lights
in use is varied.
Such being the nature and object of this my said Invention, I will
now proceed to describe the same more fully, and in order that the same
may be clearly understood I have hereunto annexed a Sheet of Drawings
illustrative thereof.
A, A, is the ordinary supply pipe made in two lengths or parts, and B
is a collar which connects the two lengths of pipe; C, the internal tube
(secured concentrically within the pipe A), the bore D of which is of
small diameter, which prevents excess of pressure of gas reaching the
burner E and thereby diminishes waste of gas.
Having thus fully described the nature and object of this my said
Invention, together with the manner in which the same is to be or may
be performed or carried into practical effect, I would have it distinctly
understood that I do not confine myself to the precise construction, but
I claim as my Invention, the application and employment of the internal
pipe C or any mere modification thereof as and for the purpose herein
fully described and shewn in the Drawings.
In witness whereof, I, the said Jacob Holdsworth, have hereunto
set my hand and seal, the Twelfth day of April, in the year of
our Lord One thousand eight hundred and seventy-two.
JACOB HOLDSWORTH. (L.S.)
