page_text: I JAMES HENRY HINDLE Calicoprinters Chemist 67 Avenue Parade Accrington
do hereby declare the nature of my invention for A MOVABLE COVERING OR
DAMPER FOR FIRES to be as follows:-
I use Asbestos cloth or other incombustible material prepared in suitable shapes
and sizes as a movable covering or damper for Fires say for instance a Sittingroom
fire by placing the cloth on the Fire at the back so as to cover about two thirds (Å)
of the surface forward it prevents that wasteful combustion of Fuel the resulting
beat and gases from which pass straight up the chimney the coal under the cloth
is coked and gradually decomposes the liberated gas escapes from under the front
edge of the cloth and ignites radiating its heat into the room on taking the cloth
off the fuel is found as a solid fire of red hot coke underneath.

Movable Covering or Damper for Fires.
I JAMES HENRY HINDLE, Calico Printers' Chemist, of 67 Avenue Parade,
Accrington, in the County of Lancaster, do hereby declare the nature of said
Invention for MOVABLE COVERING OR DAMPER FOR FIRES, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The chief object of my Invention is to economise the consumption of fuel and to
diminish the production of smoke and to effect this I employ asbestos or other
suitable incombustible material made or cut into pieces of convenient size and
shape as a movable covering or damper for fires.

page_text: In applying my Invention to a fire for domestic purposes such as a sitting room
or bedroom fire-I place the movable covering or damper on the top of the fire
extending from the back towards the front of the grate, so as to cover about
two thirds, or more or less of the top surface. The effect of placing the movable
covering or damper on the fire in this manner is to check rapid and wasteful com-
bustion of the fuel and to insure more complete combustion of the resulting gases
and smoke while the fuel under the damper cokes and gradually decomposes so
that when the damper is removed a glowing fire of red hot coke is discovered.
This movable covering or damper may be made of any suitable incombustible
material, but the material I propose to employ is asbestos made or cut into pieces
of suitable size and shape to fit the grate and preferably either woven with
selvedges, or with the raw edges turned over and hemmed to give a neat
appearance and finish.
The asbestos dampers being pliant fit closely to the top surface of the fire and
prevent through draught and so insure slow and thorough combustion. One of the
asbestos dampers may be placed on a newly made up fire and left for several hours
without the fire requiring any care or attention, and on removing the damper a
bright and glowing mass of fire will be found beneath.
Although I have only described my Invention as applied to fires for domestic
purposes, yet it is obvious that the movable coverings or dampers may be employed
on fires for any purposes whenever their use is necessary or desirable.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The manufacture of movable coverings or dampers of asbestos or other suitable
incombustible material and the use and application of such movable coverings
or dumpers to fires, substantially in the manner and for the purposes herein set
forth.
