IMPROVEMENTS IN GAS & OTHER FURNACES
Year: 1882

of the Commissioners of Patents on the 31st October 1882.
THOMAS LAYTON of Redditch in the County of Worcester Gas Manager
IMPROVEMENTS IN GAS & OTHER FURNACES
This Invention consists in constructing the sides of gas or other furnaces so that
they can be renewed at a less cost than in the ordinary way and further that they
can be renewed in the case of gas furnaces whilst under fire and without suspending
the make of gas. To effect this I build into the base of the furnace iron pins
and construct some of the fire clay blocks to fit over these pins, each row of the
blocks being tied or keyed together by flanges and grooves upon them.
The pins
are then protected from the action of the fire by being packed or coated with fire
clay. When the blocks are partially worn away, they can readily be removed by
inserting a tool underneath them and raising them off the pins; with a similar
tool new blocks can be dropped in their places.

IMPROVEMENTS IN GAS OR OTHER FURNACES.
This Invention consists in constructing the sides of gas or other furnaces so that
they can be renewed with less labour than in the ordinary way and without the
use of fire clay for setting and further that they can be renewed in the case of gas
furnaces whilst under fire and without suspending the make of gas, To effect this I
build into the base of the furnace iron or other metal studs or pins and construct
the blocks of fire clay or refractory material to fit over these pins each row of the
blocks being tied or keyed together by flanges and grooves upon them, The
pins are then protected from the action of the fire by being packed or covered
with fire-clay.
When these blocks are partially worn away they can readily be renewed by
inserting a tool underneath them and raising them off the pins. With a similar
tool new blocks can be dropped in their places.
Referring to the Drawings, Fig: 1 represents a plan of one course of blocks with one
form of key. Figs 2 and 3 are plans with other forms of keys or grooves. Fig: 4 a plan
of one course with grooves in the larger block (a) the smaller block (b) forming the
keys, the holes (c) which may be of any desired section are to receive the pins or
studs, Fig. 8. as chewn in the section Fig. 7. Figs. 6 and 7 are side and end elevations
of three tiers of blocks to form one side of the furnace.
Having thus described my Invention I wish it to be distinctly understood that I
do not confine myself to the precise details shewn in the drawings or described in
this Specification but what I claim is, the Building of Furnace sides with moveable
blocks kept in position by metal studs or pins in such a manner that they can
readily be renewed and replaced when the retorts or flues are hot as herein set
forth and specified.
In Witness whereof I the said Thomas Layton have hereunto set my hand
and seal this twenty first day of April in the year of our Lord, One thousand
eight hundred and eighty three.
