Year: 1878

page_text: LETTERS PATENT to Mark Morton, of Birmingham, in the County of
Warwick, Engineer and Machinist, for the Invention of "CERTAIN IMPROVE-
MENTS IN APPARATUS FOR CONSUMING SMOKE AND ECONOMIZING FUEL IN
STEAM BOILERS AND FURNACES."
Sealed the 9th May 1879, and dated the 13th November 1878.
PROVISIONAL SPECIFICATION left by the said Mark Morton at the Office
of the Commissioners of Patents on the 13th November 1878.
MARK MORTON, of Birmingham, in the
Machinist. "CERTAIN IMPROVEMENTS IN
County of Warwick, Engineer and
APPARATUS FOR CONSUMING SMOKE
AND ECONOMIZING FUEL IN STEAM BOILERS AND FURNACES."
My Invention has for its object the consumption of smoke and economizing of
fuel in steam boilers and furnaces.
I am aware that fixed openings with a projecting fixed inclined plate have been
used in the dead plate of steam boilers and other furnaces for the purposes above
mentioned, but in practice this fixed projecting inclined plate has been found
objectionable in firing and withdrawal of clinkers or refuse, and I am also aware
that loose doors have been placed underneath the dead plate.
But my improvements consist in so arranging this inclined or deflecting plate
and providing complete self acting means that the said plate shall rise above and
fall level with the dead plate by the opening of the fire door, and shall be kept per-
manently open when the fire door is closed for the consumption of smoke after each
firing.
This desirable object I effect by hinging the said inclined plate to the dead plate,
and by fixing or applying to the outer edge of the fire door a suitable roller fixed
in a joint or bearing which acts upon or presses against the inclined end of a lever
or levers or other equivalent secured to the frame of the fire door or other part, as

page_text: convenient. On the other end of this lever or levers I provide a loose roller or other
equivalent which bears against a projecting rib or ribs on the under side of the
deflecting plate, so that when the door of the furnace is closed after firing the roller
fixed or connected to the fire door acting upon the slanting or inclined edge of the
front end of the lever or levers will cause the other end of the lever to lift or raise
the deflecting plate above the dead plate, which will admit hot air from the ash pit
in an oblique or slanting direction upwards towards the fire door, which has the
effect of drawing the smoke and inflammable gases backwards towards the door of
the furnace, commingling with the hot air thus admitted, causing perfect combustion
and at the same time economizing the fuel.
By this arrangement it will be readily seen that by raising or lowering the roller
or other equivalent fixed or connected to the fire door or other part, the deflecting
plate in the dead plate can be placed at any angle desired above the dead plate
when the door is closed, according to the requirements of the furnace; and, further,
when the door is opened the self acting arrangement causes the deflecting plate
above the dead plate to instantly fall level with the dead plate, and so removing
every obstruction for firing or withdrawal of clinker or refuse.

MARK MORTON, of Birmingham, in the County of Warwick, Engineer. CERTAIN
IMPROVEMENTS IN APPARATUS FOR CONSUMING SMOKE AND ECONOMIZING FUEL
IN STEAM BOILERS AND FURNACES."
My Invention has for its object the consumption of smoke and economizing of
fuel in steam boilers and furnaces.
I am aware that fixed openings with a projecting fixed inclined plate have been
used with steam boilers and other furnaces for the purposes above mentioned, but in
practice this fixed projecting inclined plate has been found objectionable in firing
and withdrawing the clinkers or refuse, and I am also aware that loose doors have
been placed underneath the dead plate.
But as my improvements will be more clearly understood by referring to the
Drawings hereunto annexed I will proceed to describe the same, reference being
made to the figures and letters marked thereon.
Fig. 1 is a part longitudinal section, and Fig. 2 a part front view of as much of a
Cornish boiler and furnace door and frame necessary to illustrate my Invention,
which consists in so arranging and actuating the inclined or deflecting plate A,
shown detached in end and front views at Figs. 3 and 4, that it shall rise at its
front end above the dead plate B, B, when the door C, C, is closed, as shown at
Fig. 1, and be kept permanently open (so long as the furnace door is closed) for the
consumption of the smoke and economizing of the fuel after each firing, and when
the door C, C, is opened for firing the deflecting plate A will fall level with the
dead plate.
This desirable object is effected by hinging the said inclined or deflecting plate A
(extending nearly the whole width of the furnace) to the dead plate B, B, at each
side by the lugs D, D, working in brackets E, E, (seen in dotted lines in Fig. 2), the
centre being level with the dead plate, so that when the deflecting plate A falls into
the position shown in dotted lines on to the dead plate B by the opening of the
furnace door C, also shown in dotted lines, a close joint is preserved which will
not allow any cinders to fall in between and prevent the proper working of the
parts. On the outer edge of the fire door C I attach or secure a suitable bracket,
marked F, or its equivalent, carrying the roller G, which acts upon or presses
against the inclined edge a of the lever H working in the bracket J', secured by
preference to the underside of the door frame. On the other end of this lever H
I secure the loose roller K, or its equivalent, which acts upon the projecting rib L
formed on the underside of the deflecting plate A, so that when the door C of the
furnace is closed after firing the roller G connected with the door acts upon
the slanting or inclined edge a of the front end of the lever H and causes the
roller K on the other end to lift or raise the front edge of the deflecting plate A
above the dead plate B, as fully shown in Fig. 1, and any desired angle of
the deflecting plate A, and consequent larger or smaller opening in the dead
plate B can be easily regulated by raising or lowering the bracket F carrying
the roller G secured to the fire door, the pin M working in a slot, shown in dotted
lines at Fig. 2, for this purpose. The automatic raising of the deflecting plate A by
the closing of the door C admits hot air from the ash hole in an oblique or slanting
direction towards the fire door, thereby drawing the smoke and inflammable gases
back towards the fire door, and commingling with the hot air thus admitted causes
not only perfect combustion and complete consumption of smoke, but at the same
time greatly economizing the fuel as well as preserving the plates of the boiler,
When the door C is opened for firing the roller G leaves the inclined end of the
lever H, causing the deflecting plate A to fall level with the dead plate, as shown

page_text: in dotted lines in Figure 1, for firing or removing clinkers or refuse from the
furnace.
Having now described the nature of my said Invention, and the manner in which
the same may be carried into effect, I wish it understood that I do not purpose con-
fining myself to the exact details herein described and exhibited, as they may be
varied considerably without departing from the spirit of my Invention, but what I
claim and wish to protect by these my in part recited Letters Patent is, the self
acting arrangement, as herein described and exhibited, or any mere modification
thereof, for actuating the deflecting plate A connected with the dead plates of steam
boilers or furnaces by the opening and closing of the fire door, for the purposes
described and set forth.
In witness whereof, I, the said Mark Morton, have hereunto set my hand
and seal, this Tenth day of May, in the year of our Lord One thousand
eight hundred and seventy-nine.
Witness,
WM. LOACH.
