PROVISIONAL SPECIFICATION.
Improvements in and connected with Gas Burners.
J, ALFRED LEECH, of 44 Richmond Grove East, Longsight, in the County of
Lancashire, Engraver, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in and connected with gas burners and has
for its object to provide means which will increase the size of flame of the burner and
make it more illuminate at a less consumption of gas, than heretofore has been
the case.
My invention consists principally in the employment over the top of the burner
between its holes of a metal plate which acts as a spreader.
The top edge of this plate is preferably rounded off and the bottom formed with
two legs in such a manner as to leave a small clear space between the top and side of
the burner and the respective edge of said metal plate.
The latter may be either stationary, by being formed on the side of the burner, or it
may be made removable by employing thereon a loose collar having two slots, into
which the legs of the metal plate or spreader are placed.
On the gas issuing from the holes of the burner it passes along the said metal plate,
which when the gas is lit, then causes a spreading of the flame both in height and
width.

COMPLETE SPECIFICATION.
Improvements in and connected with Gas Burners.
I, ALFRED LEECH, of 44 Richmond Grove East, Longsight, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:
My invention relates to improvements in and connected with gas burners and has
for its object to provide means which will increase the size of flame of the burner and
make it more illuminate at a less consumption of gas, than heretofore has been
the case.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a front, and Fig. 2 a side, view of my improved spreader applied to a
burner and Fig. 3 is a plan of Fig. 2. Figs. 4, 5 & 6 are front views showing the
spreader, respectively, detached from the burner, with and without the means for
fastening it thereto. Fig. 7 is a bottom view of Fig. 5 and Fig. 8 a top view of
Fig. 6.
In carrying out my invention and referring to the figures generally my improvements
consist in the employment over the top of the burner a over one hole a¹ thereof, of a
metal plate 6 which acts as a spreader. The top edge of this plate b I form semi-
circular and the bottom with two legs c in such a manner, as to leave a small clear
space between the legs c of the said metal plate b and the side of the burner a.
The plate b may be either stationary, by being formed on the side of the burner a,
or preferably removable, by employing thereon a loose collar or ferrule d provided

with two slots or pockets into which the legs of the metal plate 6 or spreader are
placed and which form air channels &¹, in conjunction with the legs c of the plate b.
On the gas issuing from the holes of the burner a it passes along the said metal
plate b, which when the gas is lit, causes a spreading of the flame both in beight and
width.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is:-
1st. A gas flame spreader, consisting of a semi-circular plate b, placed over the
burner a substantially as and in the manner set forth.
2nd. The plate b, specified in the preceding claim, formed with legs c in combination
with a collar or ferrule d, placed around the burner a and formed with slots or
pockets c², which receive the legs c of the said metal plate 6 and form air channels b¹,
substantially as set forth.
Dated this 1fith day of August 1800.
