IMPROVEMENTS IN APPARATUS FOR PREVENTING OR CONSUMING SMOKE
Year: 1869

page_text: LETTERS PATENT to William Tipping, of Wigan, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
PREVENTING OR CONSUMING SMOKE."
Sealed the 8th March 1870, and dated the 16th September 1869.
PROVISIONAL SPECIFICATION left by the said William Tipping at the
Office of the Commissioners of Patents, with his Petition, on the
16th September 1869.
I, WILLIAM TIPPING, of Wigan, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS. FOR PREVENTING OB CONSUMING SMOKE," to be as follows:-
My improvements consist of an arrangement of one or more tubes or
pipes introduced and inserted from the face of the boiler furnace over
the fire, and to deliver air in any direction as required, either at the front
of the bridge or behind the bridge, and either through the ends of the..
tubes or pipes or through perforations in the same. These tubes or

page_text: pipes are arranged with valves, so as to admit of being opened or closed
at the will of the fireman, or man in charge, or by a mechanical con-
trivance to effect the following operations :-
When the fire-door marked A on the accompanying outline Drawing
is opened the valve at C is opened and the valve at D is closed, and when
the fire-door A. is shut the valve at C remains open and the valve at D
remains shut, and when the fire-door B is opened the valve at D opens
and the valve at C shuts, and when the fire-door B is closed the valve
at D remains open and the valve at C shut until the operations are
repeated. The fire-doors A, B, are connected with the valves at C
and D, so as to perform the above operation.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Tipping in the Great Seal Patent Office
on the 15th March 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TIPPING, of Wigan, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Sixteenth day of September, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Tipping, Her special license that
I, the said William Tipping, my executors, administrators, and assigns,
or such others as I, the said William Tipping, my executors, adminis-
trators, 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 APPARATUS
FOR PREVENTING OR CONSUMING SMOKE," upon the condition (amongst others)
that I, the said William Tipping; 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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Tipping, 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 (that is to say) :—
My improved apparatus for preventing or consuming smoke will be
clearly understood by the following particular description thereof,
reference being had to the figures and letters on the accompanying
Sheet of Drawings, in which Figure 1 is an end elevation, and Figure 2
a longitudinal section of one end of a two-flued boiler.
The improvements consist of an arrangement of one or more tubes or
pipes introduced and inserted from the face of the boiler over the fire to
deliver air in any direction as required, either at the front of the bridge
or behind the bridge, and either through the ends of the tubes or pipes
or through perforations in the same. These tubes or pipes are arranged
with valves, so as to admit of being opened and closed by the fireman, or
man in charge, or by a mechanical contrivance in connection with the
fire-doors.
In Figure 1 I represent the employment of several tubes or pipes and
valves for each flue, the valves being worked by mechanism connected
to them and the fire-doors to effect the following operations:―
When the fire-door A is opened the valves C are opened and the
valves D closed, and when the fire-door A is shut the valves C remain
open and the valve D remain closed, and when the fire-door B is opened
the valves D are opened and the valves C are closed, and when the fire-
door B is shut the valves D remain open and the valves C closed until
the operations are repeated.
In the Figures I have represented the application of five tubes and
valves to each furnace, but one tube and valve or any other number
may be used as required.
It will be seen that the object of this Invention is to supply air
through the tubes or pipes to the furnace when it is fed with fuel, and
to maintain the supply of air until another furnace is fed with fuel, and
so on alternately when a boiler has two furnaces, but when there are
more furnaces, as in large marine boilers, they may be supplied with air

page_text: through the tubes or pipes, either alternately or consecutively, the
mechanism connected to the valves and fire-doors being modified to suit
the requirements.
In witness whereof, I have hereto set my hand and seal, the
Twenty-second day of December One thousand eight hundred,
and sixty-nine.
