IMPROVEMENTS IN STOVES OR FIRE-GRATES
Year: 1882

page_text: LETTERS PATENT to Adam Cyrus Engert, of Three Mills Lane, Bromley-by
Bow, in the County of Middlesex, for an Invention of "IMPROVEMENTS IN
STOVES OR FIRE-GRATES."
PROVISIONAL SPECIFICATION left by the said Adam Cyrus Engert at the
Office of the Commissioners of Patents on the 9th January 1882.
ADAM CYRUS ENGERT of Three Mills Lane Bromley by Bow in the County
of Middlesex. "IMPROVEMENTS IN STOVES OR FIRE GRATES."
This Invention has for its object improvements in stoves or fire grates.
My improved stove or fire grate consists of a fuel holder or receiver in the
form approximately of one half of a barrel divided longitudinally. The receiver
tapers considerably towards the ends and has longitudinal edges within it. It is
mounted on pivots so that it may turn about an horizontal axis. The ends of
the receiver are enlarged into cheeks which prevent the fuel falling out at the
ends in any position in which the receiver may be placed. On these cheeks
sockets are formed to take the end of a poker or rod by which the receiver can
be turned partly round as it is required at the time of feeding the fire.
The normal position for this receiver is with the front edge depressed below and
the back edge elevated above the level of the pivots.
The fire is then contained partly within the receiver and partly it is supported
against stationary bars which stand up above the front edge of the receiver and rise
about to the level of the pivots.
For the purpose of feeding the fire the receiver is tipped or turned so as to raise
its front edge and then it scoops up into it all the fire which previously rested
against the front bars. The receiver is turned so far round that the fire is tipped
to the back of the receiver this then becoming the lowest part. The fresh fuel is
put into the receiver at the front into the vacant space and the receiver is then
turned back to its former position. The effect of this is to carry down the fresh
fuel and to raise the ignited fuel until the latter rolls over within the receiver and
comes to be supported partly against the front bars.

page_text: The fresh fuel is then found covered completely by the hot or ignited fuel and
the complete combustion of the vapours which the fresh fuel emits as it becomes
hot is thereby effected.
The pivots are formed on stationary cheeks or supports which are connected in
front by the bars and at the back by a concave concentric with the pivots and just
sufficiently large to allow the receiver to turn within it.
Above the concave is the space or opening leading to the chimney it is fitted
with a register door which is hinged at its front or upper edge to the inner side
of the stove front.
I employ a curved plate or air guide beneath the fire bars to prevent the passage
of air beneath and behind the receiver and to direct it upwards through the front
part of the fire

ADAM CYRUS ENGERT of Three Mills Lane, Bromley-by-Bow in the County
of Middlesex. "IMPROVEMENTS IN STOVES OR FIRE GRATES."
This Invention has for its object improvements in stoves or fire grates.
My improved stove or fire grate consists of a fuel holder or receiver in the form
approximately of one half of a barrel divided longitudinally.
The receiver tapers considerably towards the ends and has longitudinal ridges
within it. It is mounted on pivots so that it may turn about an horizontal axis.
The ends of the receiver are enlarged into cheeks which prevent the fuel falling
out at the ends in any position in which the receiver may be placed. On these
cheeks sockets are or may be formed to take the end of a poker or rod by which
the receiver can be turned partly round.
The normal position for this receiver is with the front edge depressed below and
the back edge elevated above the level of the pivots.
The fire is then contained partly within the receiver and partly it is supported
against stationary bars which stand up above the front edge of the receiver and
rise about to the level of the pivots.
The pivots are formed on stationary cheeks or supports which are connected in
front by the bars and at the back by a concave concentric with the pivots and just
sufficiently large to allow the receiver to turn within it.
Above the concave is the space or opening leading to the chimney, it is fitted
with a register door which is hinged at its front or upper edge to the inner side of
the stove front.
I employ a plate or air guide beneath the fire bars to prevent the passage of air
beneath and behind the receiver and to direct it upwards through the front part of
the fire.
In order that my said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view of my improved fire stove or grate. Figure 2 is a
transverse vertical section of the same.
a, is the stove front. b, is the barrel like fire holder or receiver, and b¹, b', are
pivots upon its two ends. 6² are slots in this barrel. c, c, are the cheeks or supports
in which the pivots are supported. d, is a concave connecting the cheeks. e, are
the front bars of the grate. f is an inclined plate beneath the concave preventing
the current of air passing behind it and directing the air upwards to the front
bars, g, is the register-door. h, is a pawl engaging with ratchet like teeth upon
one end of the barrel like fuel holder, and serving to retain the fuel holder
with the preponderating weight behind. k, k, are pins between which a poker or
rod is inserted when it is desired to turn the fire fuel holder. My improved
stove or grate can be used in the manner described in my Provisional Specifi-
cation, and also most advantageously as a slow combustion stove.
The grate is
filled complelely full of fuel, an operation which is facilitated by the rotation of
the fuel holder, and the fire is lighted at the front. As the fuel burns slowly away
the fire is supplied by fuel descending from the upper part of the fuel holder.
When the fire gets low it can be brought to the front by turning the fuel holder.

page_text: The register door g, is arranged to slide towards the back to increase when
desired the passage to the chinney at g¹.
Figure 3 represents another arrangement of the register; here it is pivotted in
front and lifts at the back, it is retained in the desired position by a toothed arc.
Having thus described the nature of my said Invention and the manner of
performing the same I would have it understood that I claim my improved firo
grate or stove, with barrel like fuel holder b, and front bars e, substantially as
described.
In witness whereof I the said Adam Cyrus Engert have hereunto set my
hand and seal this Thirtieth day of June in the year of our Lord One
thousand eight hundred and eighty two.
