IMPROVE- MENTS IN MEANS OR APPARATUS TO FACILITATE THE GENERATION OF STEAM IN STEAM BOILERS."
Year: 1880

page_text: LETTERS PATENT to Thomas Jones, of Maindy House, near Pontypridd, in the
County of Glamorgan, Colliery Proprietor, for an Invention of "IMPROVE-
MENTS IN MEANS OR APPARATUS TO FACILITATE THE GENERATION OF STEAM IN
STEAM BOILERS."
PROVISIONAL SPECIFICATION left by the said Thomas Jones at the Office
of the Commissioners of Patents on the 17th January 1880.
THOMAS JONES, of Maindy House, near Pontypridd, in the County of Glamorgan,
Colliery Proprietor. "IMPROVEMENTS IN MEANS OR APPARATUS TO FACILITATE THE
GENERATION OF STEAM IN STEAM BOILERS."
In carrying out my improvements I apply to the boiler a pipe for the conduct
of part of the steam generated in one or more jets to the interior of the furnace
with taps or valves to regulate the supply. The outlets of the stean passages are
applied so as to act on the flame and other products of combustion generated in the
fire places over the fire door, or doors, or other suitable places.
In place of only one steam pipe for the conduct of the steam to the furnace there
may be two or more of such pipes.
I apply a damper capable of regulation to regulate the escape of the products of
combustion before they enter the stack.
By these means considerable saving of fuel and labour will be effected.

THOMAS JONES, of Maindy House, near Pontypridd, in the County of Glamorgan,
Colliery Proprietor. "IMPROVEMENTS IN MEANS OR APPARATUS TO FACILITATE THE
GENERATION OF STEAM IN STEAM BOILERS."
In carrying out my improvements I apply to the boiler a pipe for the conduct of
part of the steam generated in one or more jets to the interior of the furnace with
taps or valves to regulate the supply. The outlets of the steam passages are
applied so as to act on the flame and other products of combustion generated in the
fire places over the fire door, or doors, or other suitable places.

I apply a damper capable of regulation to regulate the escape of the products of
combustion before they enter the stack.
'
By these means considerable saving of fuel and labor will be effected.
But that the Invention may be the better understood I will, by the aid of the
accompanying Drawings, proceed to describe means pursued by me in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows by an end view and Figure 2 by longitudinal section an arrange-
ment of boiler with parts applied according to my Invention. In both Figures the
same letters indicate corresponding parts. a indicates the boiler; b, b, the furnaces
or fire places in this boiler; c, the fire bridge; d, the flue space; and e, the ash pit;
f indicates a pipe for receiving a portion of the steam generated in the boiler, and
by the branches f¹, f', conducting such steam to the upper part of each fire place
or furnace, so that the steam as there allowed to escape regulated by taps f³ may
freely act upon the flame and products of combustion generated in the respective
fire places, to increase the combustion of the fuel in the fire places, and thereby
facilitate the generation of steam in the boilers; g is a damper.
Having thus described my Invention, and means which I adopt in carrying the
same into effect, I would have it understood that what I claim is, the arranging
or combining parts whereby the generation of steam in steam boilers is facilitated,
substantially as described.
In witness whereof, I, the said Thomas Jones, have hereunto set my. hand
and seal, this Sixteenth day of July, in the year of our Lord One thousand
eight hundred and eighty.
