Year: 1872

page_text: LETTERS PATENT to George Thorneloe, of No. 34, London Wall, Gas
Engineer, for the Invention of "AN IMPROVED DIP PIPE ZORMING PART
or Gas ApparatUS FOR USE IN Maxing Gas.”
PROVISIONAL SPECIFICATION left by the said George Thorneloe at
the Office of the Commissioners of Patents, with his Petition, on
the 25th November 1872.
I, GEORGE THORNELOE, of No. 84, London Wall, Gas Engineer,
do hereby declare the nature of the said Invention for "AN IMPROVED
DIP PIPE FORMING PART OF GAS APPARATUS FOR USE IN MAKING Gas," to be as
follows:-
This Invention has for its object improvements in dip pipes used for
sealing, unsealing, or regulating seal, in the hydraulic main. For this
purpose I employ a wrought or cast iron dip pipe made to work through
a stuffing box or stuffing boxes, the said dip pipe to be raised or lowered
to any required seal, or unsealed, by means of a rod fixed on the same,
the said rod to work through a stuffing box on top of H pipe or
hydraulic main, and to be raised] or lowered by means of a screw or
lever on said rod, the said lever to be fixed on bridge pipe, hydraulic
main, ascension pipe, or otherwise, as most convenient, all which will

page_text: clearly appear by the Drawing marked A, and the references thereto
marked B, forming part of this my Provisional Specification.
DESCRIPTION OF THE DRAWING.
A is the wrought or cast iron dip pipe; B, the stuffing box through.
which the dip pipe works; C, the rod for raising or lowering the dip 5
pipe; D, the stuffing box through which the rod C works; E, the
hydraulic main; F, the screw for raising or lowering the dip pipe;
G, the lever for raising. or lowering the dip pipe; H, the bridge pipe ;
I, the ascension pipe.
SPECIFICATION in pursuance of the conditions of the Letters Patent 1
filed by the said George Thorneloe in the Great Seal Patent Office
on the 24th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
THORNELOE, of No. 34, London Wall, in the City of London, Gas
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of November, in the
year of our Lord One thousand eight hundred and seventy-two, in
the thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto the said George Thorneloe, Her special
licence that I, the said George Thorneloe, my executors, adminis-
trators, and assigns, or such others as I; the said George Thorneloe,
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 "AN IMPROVED DIP PIPE FORMING PART OF GAS APPARATUS FOR USE IN
MAKING GAS," upon the condition (amongst others) that I, the said
George Thorneloe, 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.

page_text: NOW KNOW YE, that I, the said George Thorneloe, 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 :-
My Invention is designed for improvements in dip pipes used for
sealing, unsealing, or regulating seal in hydraulic main A. For this pur-
pose I employ a wrought or cast iron dip pipe B made to work through
a stuffing box C, the said dip pipe B to be raised or lowered to any
required seal, or unsealed by means of the rod D fixed on the bottom of
the dip pipe B, shewn in Drawings Fig. 1, hereunto annexed; the said
rod D to work through stuffing box E and to be raised or lowered by
means of lever F on said rod D, the said lever F to be fixed on bridge
pipe G and on bottom of ascension pipe H, so that when the dip pipe B
is raised and unsealed by the means of lever handle L the down rod I
is lowered in front of retort lid on mouthpiece J, preventing the said
retort lid from being removed until the said rod I is raised and the dip
pipe B sealed, thus preventing back pressure of gas; K shews cock for
oiling, steaming, or cleaning around dip pipe B; M shews liquor in
hydraulic main A. When the dip pipe B is only required to be
regulated, as the hydraulic main A may settle or otherwise, the dip
pipe B can be regulated by means of a screw on rod d and wheel N on
top, shewn on the Drawings hereunto annexed, Fig. 2.
Having thus described the manner in which my Invention is carried
into effect, I wish it to be understood that I do not limit myself to the
precise details herein-before described, as the same may be varied
without departing from the nature of my Invention; but what I do
claim as my Invention is the regulating dip pipe B in combination with
the stuffing box O, rod D, stuffing box E, lever F, rod I, handle L.
In witness whereof I have hereunto set my hand and seal this
Twenty-fourth of May One thousand eight hundred and seventy-
three.
