IMPROVEMENTS IN STEAM BOILERS OR PROVISIONAL SPECIATION
Year: 1872

page_text: LETTERS PATENT to Solomon Sanderson and Albert Proctor, both of
Huddersfield, in the County of York, copartners, carrying on
business as Engineers, under the style or firm of Sanderson and
Proctor, for the Invention of "IMPROVEMENTS IN STEAM BOILERS OR
PROVISIONAL SPECIFICATION left by the said Solomon Sanderson and
Albert Proctor at the Office of the Commissioners of Patents, with
their Petition, on the 25th October 1872.
We, SOLOMON SANDERSON and ALBERT PROCTOR, both of Hudders-
field, in the County of York, copartners, carrying on business as
Engineers, under the style or firm of Sanderson and Proctor, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN STEAM
BOILERS OR GENERATORS, AND THE FURNACE ARRANGEMENTS THEREOF," to be as
follows:-
We construct our boilers or generators in globular form with hot air
tubes passing through the same, and we also add if required a ring or

page_text: endless tube providing a steam or water space communicating with the
steam and water space of the globular part. Such ring or endless
tube being available as a superheater or as an additional steam space.
The furnace arrangements consist of fire-bars concentrically arranged
so as to converge to central upright shafting, which should be tubular to
allow the same to be prolonged and connected with the bottom of the
boiler so as to be utilized for the blow-off and the entrance for feed
water to the boiler, one end of each such fire-bar can thus be supported
on such shafting and the bars be revolved by means of a turntable and
by a pendent to each bar, and by this pendent coming in contact with a
stationary bar or by gearing the fire-bars can be continually tilted so as
to remove clinkers and reduce the amount of stoking required. The bars
are to be inclined towards the central shafting so as to cause the fire to
correspond with the form of the boiler. The furnace can be fed by a
hopper or otherwise.
Instead of having as above described hot air tubes passing through
the water space to the boiler we can if desired reverse this arrange-
ment and have water tubes and fire and heat space surrounding
them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Solomon Sanderson and Albert Proctor in the
Great Seal Patent Office on the 25th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SOLOMON
SANDERSON and ALBERT PROCTOR, both of Huddersfield, in the County
of York, copartners, carrying on business as Engineers under the style
or firm of Sanderson and Proctor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Solomon Sanderson and Albert Proctor,
Her special licence that we, the said Solomon Sanderson and Albert
Proctor, our executors, administrators, and assigns, or such others as
we, the said Solomon Sanderson and Albert Proctor, our executors,

page_text: "
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 STEAM
BOILERS OR GENERATORS, AND THE FURNACE ARRANGEMENTS THEREOF,'
upon the
condition (amongst others) that we, the said Solomon Sanderson and
Albert Proctor, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and scals, 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 we, the said Solomon Sanderson and Albert
Proctor, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
We construct our boilers or generators in globular form, with hot air
tubes passing through the same, and we also add, if required, a ring or
endless tube providing a steam or water space communicating with the
steam and water space of the globular part, such ring or endless tube
being available as a superheater, or as an additional steam space.
The furnace arrangements consist of fire-bars, concentrically arranged
so as to converge to a central upright shafting, which should be tubular
to allow the same to be prolonged and connected with the bottom of
the boiler, so as to be utilized for the blow-off and the entrance for feed
water to the boiler, one end of each such fire-bar can thus be supported
on such shafting, and the bars be revolved by means of a turntable and
by a pendant to each bar (which pendant comes in contact with a
stationary bar) or by gearing, and so the fire-bars can be continually
tilted, so as to remove clinkers and reduce the amount of stoking
required. The bars are to be inclined towards the central shafting, so
as to cause the fire to correspond with the form of the boiler. The
furnace can be fed by a hopper, or otherwise.
Instead of having as above-mentioned hot air tubes. passing through
the water space of the boiler, we can, if desired, reverse this arrange-
ment, and have water tubes and fire or heat space surrounding them.

page_text: In compliance with the said condition in the said Letters Patent
contained, thus far we have particularly described and ascertained the
nature of the said Invention, and have incidentally in general terms
described in what manner the same is to be performed or put in practice,
now in further compliance with the said condition we proceed to fully
and particularly describe and ascertain in what manner our said Inven-
tion is to be performed or put in practice by referring to the Drawings
accompanying this Specification, the description whereof is to be read in
conjunction with the herein-before contained descriptive statements
above referred to.
Figs. 1 and 2, sectional elevations; Fig. 3, plan. In these Figures
A denotes the man-hole; B, B, B, B, pipes leading from boiler to (C)
circular steam chest; C, circular steam chest; D, safety valve; E, steam
pipe; F, blow-off and feed pipe combined; G, boiler.
Having now particularly described and ascertained the nature and
object of the said Invention, and in what manner the same is to be
performed or put in practice, we hereby declare that we claim the said
Invention of "Improvements in Steam Boilers or Generators, and the
Furnace Arrangements thereof," the nature and character whereof are
herein-before described and illustrated by the Drawings accompanying
this Specification; it being understood that we do not limit ourselves to
the exact details exhibited by the said Drawings and herein described.
In witness whereof, we, the said Solomon Sanderson and Albert
Proctor, have hereunto set our hands and seals, this Nineteenth
day of April, in the year of our Lord One thousand eight hundred
and seventy-three.
