Improvements in and connected with Furnaces and Fireplaces.
I, EPHRAIM TAYLOR, Central Works, Blackburn, in the County of Lancaster,
Manufacturer of Fuel Economisers, do hereby declare the nature of this inven-
tion to be as follows:-
The object of this invention is to consume smoke given off in furnaces and
fireplaces. This result is obtained by specially constructed apparatus and
appliances.
Firstly I construct a grate bar made partly wedge shape with slots cut through
at an angle. The bottom edge is undulated after the manner of a saw. The
air which travels between the bars comes in contact with the slots causing an
upward current into the furnace. The air mingles with the smoke, causing com-
bustion.
Secondly I construct a metal box made partly ☐ shape and left open at the
front. The top is fitted with a cap perforated with holes. The box is built in
the bridge wall of steam boilers in a suitable position being left open to the
ashes chamber to receive air I make a semicircular plate to fit the ashes chamber
at the back end leaving a cavity between the bridge wall and the said plate left
open at the top to receive air. The air descends into the cavity and ascends
into the box and ascends through the perforated cap at the top into the furnace
behind the bridge wall and mingles with the main volume of smoke and effects
combustion.
Thirdly I make a flat ring with a hollow cross attached and bevel rings varying
in diameter placed one above the other. These are attached to the flat ring. This
apparatus is attached underneath the grate bars of vertical steam boilers. This
apparatus answers as a fan blowing into the furnace. The air mingles with the
main volume of smoke and effects combustion.

Improvements in and connected with Furnaces and Fireplaces.
EPHRAIM TAYLOR, Central Works, Blackburn, in the County of Lancaster,
Manufacturer of Fuel Economisers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement: -
This invention consists of a grate bar made partly wedge shape with slots cut

page_text: through at an angle the bottom edge being undulated after the manner of a saw
as shown in Fig. 1, 2 and 6. Secondly I construct a metal box made partly
L shape and left open at the front and the top is fitted with a cap peforated with
holes as shown in Fig. 1, 2 and 4. The box is built in the bridge wall of steam
boilers as shown in Fig. 1 and 2 being left open to the ashes chamber to receive
air. I make a semicircular plate to fit the ashes chamber at the back end leaving
a cavity between the bridge wall and the said plate as shown at a in Fig. 1 the
said plate being left open at the top as shown at b in Fig. 2 and 3, to receive air.
The air descends into the cavity and ascends through the box and out at the per-
forated cap at the top into the furnace behind the bridge wall and mingle with
the main volume of smoke and effects combustion.
Thirdly I make a flat ring with a hollow, cross attached as shown in Fig. 7
and 8 and bevel rings varying in diameter, Fig. 9 and 10 showing one of the
said bevel rings, the said bevel rings being placed one above the other; these
are attached to the said flat ring as shown in Fig. 11 and 12. This apparatus is
made of sheet metal and is attached with bolts underneath the grate bars of
vertical steam boilers as shown in Fig. 12. This apparatus is adapted for steam
boilers belonging to steam fire engines, the apparatus causing an upward current
of air into the furnace when the said steam fire engine is travelling thereby
causing better combustion.
Fourthly I make the aforesaid grate bar as shown and described of suitable
size to fit ordinary fireplaces as shown at c in Fig. 13.
Fifthly I make the aforesaid box as shown and described of suitable size the
said box being built in the brickwork behind the fire as shown at d in Fig. 13.
The air ascends through the said box and out at the perforated cap at the top
into the fire and mingles with the main volume of smoke and effects combustion.

2nd. The construction of box and plate as shown and described for the pur-
pose set forth.
3rd. The construction of the apparatus as shown and described.
Dated the 3rd day of August 1900.
