We, RICHARD HATTERSLEY, CHARLES HATTERSLEY, and THOMAS
HATTERSLEY, all of Swinton, in the Parish of Wath-upon-Dearne, in the
County of York, Trading under the name of Hattersley Brothers and
Company, Stove Grate Manufacturers, and HOWARD MATRAVERS
ASHLEY, of Sheffield, in the said County, Designer, do hereby declare
the nature of our said Invention for " IMPROVEMENTS IN STOVE GRATES FOR
ECONOMIZING FUEL, AND IN THE APPARATUS AND MEANS CONNECTED THEREWITH,”
to be as follows :—
The Invention relates more particularly to improvements in that class
of stove grate known as the "register stove grate," but may with equal
advantage be adapted to other domestic grates. It is designed for the
purpose of economizing fuel, first by a novel arrangement in the
construction of the grates, whereby warm air will be generated and
diffused into the room or apartment in which it is situated, and secondly
"

page_text: by a novel arrangement of feeding apparatus in connection with the
grate, whereby the fire will be supplied with fuel in a manner that will
effectually consume the smoke evolved from the same.
The novel construction of the grato and the various parts constituting
these improvements may be thus described.
First. The front moulding or ornamental design of the stove or grate
is composed of a hollow shell or frame which forms a hot air or water
chamber. In this chamber a curvilinear or serpentine pipe is placed in
a position that will allow air to enter through an inlet orifice placed at
the lower portion of the moulding of the grate. The air so entering as 1
it becomes warmed by the radiation of heat from the heated sides of the
hollow frame surrounding the fire circulates and passes through and out
of the pipe at the upper portion of the grate into the room and so
diffuses warmth.
If desired the hollow spaces of the moulding may contain water which 1
when heated will also be a means of heating the air passing through the
pipes.
Secondly. The improvements relate to the means employed for
supplying and feeding the fire with fuel. For this purpose the front
portion of the framing of the stove below the moulding forms a lid or 2
valve, which when pulled forward works or turns on a quadrant hinge
behind the framing which also supports a coal receptacle or box supplied
with a lid. This coal receptacle when the lid or valve is pulled
forward assumes a position that will allow it to be supplied with fuel,
after which the orifice exposed by the opening of the valve or lid in 2
front of the grate is closed, and the coal receiver is returned to its
normal position.
The coal receptacle at its lower portion is provided with a revolving
propeller, and an orifice and channel beyond leading direct into the
back and lower portion of the fire.
The axis of the revolving feeder or coal propeller is provided with a
·wheel which is driven by suitable gearing connected with a bandle in
front, the action of which by hand intermittently propels and feeds the

gradually forced into the fire underneath the burning fuel, thus causing
the gases evolved from the fuel as they pass through the fire to be
wholly consumed, preventing thereby the formation of smoke, which
being burnt or consumed is a further means of economizing fuel.
