I ALFRED LEACH of the firm of The Manchester Gas Engineering Coy. Knowsley
Works Cheetham Manchester and ELI PLATTS GREENWOOD Foreman to the above
works do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in gas fires.
We arrange a number of narrow fret castings across the fire in a vertical position,
or on edge one above another, and in two or more rows in front of each other,
mounted on brackets, or bearers, one on each side of the fire.
These brackets have two or more rows of U projections in a vertical position, one
above another, and in front of each other. These brackets have also a strip cast
on at an angle to suit brick, so that this strip beds against front, and bits are cast
on that fit in recesses in front, to keep them in position when brick is nipped against
it, causing the parts of brackets with U projections to face each other ready to
receive the fret castings. Each fret casting to have two projections, or pivots at
each end, which are intended to fit in the recesses formed by the U projections,
thereby holding it in an upright position.
The U projections are so arranged that when in position, the bottom edge of fret
castings in the front row is about level with the top of teats, or outlet nozzles of
Bunsen burner, and the fret castings behind to stand about half the width of itself
higher. When a number have been put across the fire vertically, and directly
above each other, the back row will finish about half the width of the fret castings
above the front row.
These fret castings are interchangeable, so that when the bottom ones show signs
of perishing with the heat being more intense in some parts than others, they can
be quickly, & easily changed, therefore the whole set can be completely worn out
before being replaced by new ones. We also arrange a number of large lumps on
the brick directly above the top of fret castings, so that they stand further out than
the aforesaid castings, and so prevent the heat from passing away too quickly.

to the above works 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 :-
This invention relates to gas fires in which the metal fret work becomes incan-
descent by means of a number of Bunsen gas flames. We arrange a number of
narrow fret castings across the fire space in a vertical position, one above another
and in two or more rows in front of each other, mounted on bearers or fret holders
one on each side of the fire, with U projections to receive the frets. The U projec-
tions are so arranged that when the frets are in position, the bottom edge of the
lower fret casting in the front row is about level with the tops of the nipples of
Bunsen burner, and the bottom fret castings behind will stand about half the width
of itself higher. When a number have been put across the fire space vertically &

page_text: above the front row.
The fret castings are interchangeable so that when the bottom ones show signs of
decay with the heat being more intense in some parts than others, they can be
quickly & easily changed, therefore the whole set can be completely worn out before
being replaced by new ones.
We also arrange a number of large lumps on the brick directly over the top of
fret castings, so that they stand further out than the aforesaid castings, and so
prevent the heat from passing away too quickly.
In order that the invention may be clearly understood and easily applied, we
have appended hereunto a set of drawings illustrative of our improvements.
Figure 1 is a front elevation of our improved gas fire.
Figure 2 is a part sectional elevation of Figure 1.
Figure 3 is a plan of Figure 1 part sectional.
Figure 4 is a front elevation of fret holder shown detached from front 1 showing
part of fret 2 in U projection.
Figure 5 is a side elevation of Figure 4.
Figure 6 is a plan of Figure 5.
The metal frets 2, are the front fret work castings above each other, see
Figure 1, 2 & 3.
The back fret work castings 2 also stand above each other, starting half the
width of a fret casting higher than the front ones, and finishing half the width above
as shown in Figure 2.
All the frets 2, and 2ª, have two points 3ª cast on at each end to fit in Ụ projec-
tions 3. The two fret holders 4 right and left hand have U projections or bearers 3
cast fast, which U projections receive the pivots 3ª on the frets 2 & 2ª, thereby
holding the frets in a vertical position as shown in Figures 1, 2, 3.
Projections 5 cast on fret holders fit in recesses 5ª on front, to keep them in proper
position.
When the brick 6 is nipped against flange 7, it sets the fret holders square each
way, with U projections facing each other ready to receive the frets, and requires
no other fastening.
The Bunsen burner 8, has the nipples 9, set zigzag so as to better distribute
the flame over the frets 2 and 2 which frets are arranged to span the burner
nipples 9 as much as possible, as shown in Figures 1, 2, 3.
Brick 6 for fire back has several large irregular lumps 10 along the top projecting
beyond the fret castings, which keeps a volume of heat amongst the frets and
prevents it passing away too quickly.
Having now fully described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is,
First In gas fires the application of two fret holders, one on each side of the
fire as shown and described.
Second-In gas fires the fret castings to stand above each other, and in front of
each other. The back fret to stand half its width above the front bottom one, and
the back top one to finish half its width above the front top one, as shown and
described.
