Improvements in the Arrangement of Fire Bars for Boiler and other
Furnaces, Domestic Fire Grates and the like.
I, JOHN HOUGH, of 104, Raper Street, Oldham, in the County of Lancaster,
Heating Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the arrangement of fire bars for
boiler and other furnaces, domestic fire grates and the like, and the object of
my improvements is to insure more perfect combustion and greater economy
in the use of fuel.
In carrying my improvements into effect I employ rather deeper fire bars
than hitherto customary and arrange them in parallel rows lengthwise of the
furnace or grate but instead of setting the bars straight or vertically as usual
I fix them, according to my improvements, at a suitable inclination sloping
alternately right and left so that the fire bars converge towards one another in
The fuel
pairs having alternate wide and narrow openings above and below.
rests in the V shaped spaces between the bars as well as upon them and the
air enters freely through the spaces between the bars and by their inclined
arrangement is guided further into the fire and so supports combustion more
effectually than when ordinary straight set bars are employed.
Boiler and other furnaces as well as house grates may be formed of fire bars
arranged as described but for existing grates the bars may be set in a frame
and placed a convenient distance above the ordinary bars as a false grate.
Dated this 18th day of November 1899.

Improvements in the Arrangement of Fire Bars for Boiler and other
Furnaces, Domestic Fire Grates and the like.
I, JOHN HOUGH, of 104, Raper Street, Oldham, in the County of Lancaster,
Heating 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 the arrangement of fire bars for
boiler and other furnaces, domestic fire grates and the like, and the object of
my improvements is to insure more perfect combustion and greater economy,
in the use of fuel.

page_text: In the accompanying sheet of drawings-
Figure 1 is a side elevation of one of the fire bars and Figure 2 is an end
elevation showing the arrangement of fire bars according to my improvements.
In these views, a designates the fire bars each of which is made rather deeper
than hitherto customary and I arrange these bars in parallel rows, as indicated
in Fig. 2 lengthwise of the furnace or grate but instead of setting the bars
straight or vertically as usual I fix them, according to my improvements, at a
suitable inclination sloping alternately right and left so that the fire bars
converge towards one another in pairs having alternate wide and narrow openings
above and below. The fuel rests in the ✓ shaped spaces between the bars as
well as upon them and the air enters freely through the spaces between the
bars and by their inclined arrangement is guided further into the fire and so
supports combustion more effectually than when ordinary straight set bars are
employed.
The fire bars are preferably perforated with holes a' through which air to
support combustion can flow freely.
Boiler and other furnaces as well as house grates may be formed of fire bars
arranged as described but for existing grates the bars may be set in a frame
and placed a convenient distance above the ordinary bars as a false grate.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The arrangement of obliquely set fire bars in order to form V shaped spaces
between them substantially as and for the purposes herein set forth.
