IMPROVEMENTS IN AND APPER- TAINING TO GLASS TANK FURNACES
Year: 1879

page_text: LETTERS PATENT to Job Henry Lyon, of Peasley Glass Works, St. Helens, in
the County of Lancaster, for the Invention of "IMPROVEMENTS IN AND APPER-
TAINING TO GLASS TANK FURNACES."
PROVISIONAL SPECIFICATION left by the said Job Henry Lyon at the Office
of the Commissioners of Patents on the 14th February 1879.

caster.
This Invention consists essentially in placing the fire in the centre of the furnace,
whether the latter be square, round, polygonal, or oval.
I make the tank or seige preferably of a circular form, and separated from the fire
by a hollow bridge as at present.
The outer walls are preferably circular too.
The flame from the furnace strikes the crown, and curls round over the glass
and through the working holes. These latter are situated all round the furnace
instead of at the two sides only, as in ordinary tank furnaces. By this means the
supply of heat to every part of the tank is more uniform, and the entire circum-
ference of the furnace is utilized for working purposes.
The furnace is preferably fed and stoked from below.

This-Invention-consists-essentially in placing the fire in the centre of the tank,
whether the latter be square, round, polygonal, or oval.
I make the tank or siege preferably of circular form, and separated from the fire
by a hollow bridge, as at present.
The Drawings describe an actual apparatus erected by my firm at the Peasley
glass works.
A is the chimney, preferably but not necessarily circular; B, arched
roof of tank; C, C, working holes; D, siege or tank; E, inner wall of tank, pre-
ferably circular; F, furnace bars; these are preferably used with a mechanical stoker
stoking up the fuel from below; G, furnace sides; H, air flues bridged over at top,
except at points J, J. The flame from the furnace strikes the crown B, and curls
round over the glass in tank D, through the working holes C, and up the chimney A
in the usual manner. The working holes are placed at intervals all round the furnace
as convenient, instead of as in ordinary tank furnaces on two sides only. By this
means the supply of heat to every part of the tank is more uniform, and the entire
circumference of the furnace is utilized for working purposes.
Having now described my Invention, and the best mode known to me of carrying
it into effect, I wish it to be understood that I do not confine myself to the exact
contour or arrangement herein described and shown, as it is not necessary that the
furnace should be round, a slightly elliptical, polygonal, or semi polygonal and curved
contour acting almost as well in practice, but that what I believe to be new and
desire to protect under the herein before in part recited Letters Patent is,-
I. The mode hereindescribed of firing glass tank furnaces by placing the com-
bustion furnace in the middle of the tank, and causing the flame to radiate outwardly
therefrom over the tank to working holes placed at approximately equal distances
from the combustion furnace.
II. The glass tank furnace herein described, having a combustion furnace in the
centre, and the working holes all round or nearly so, instead of on the two sides
only, as has hitherto been the practice.
In witness whereof, I, the said Job Henry Lyon, have hereunto set my hand
and seal, this Eleventh day of July, in the year of our Lord One thousand
eight hundred and seventy nine.
