My Invention consists of a Pan or Tray about one & a half inches deep more of
less & made of cast Iron or other metal, having a number of slots or Holes at the
bottom, these slots or holes have flanges cast or formed all round & projecting
upwards.
The spaces between the flanged slots or holes I fill with fire clay or any fire-resisting
cement.
The Iron pan or Tray may be cast or formed in one piece, or may be constructed of
a number of loose pans or Troughs made of Iron or other metal & fitted with a metal
frame, so that any of them may be readily taken out for repairs, a space must be left
between each pan or tough to admit air to the fire & also to allow the ashes falling
through. These Troughs or pans I fill with fire clay or other cement.
The advantages of my Invention are as follows-
1st. The fire Brick or cement fitted into a pan having flanged slots.or Holes, or into
loose pans or Troughs, is much more durable than a perforated fire brick not thus
fitted.
2ndly. The fire burning upon perforated fire Brick is much cleaner & brighter
than if burning on an ordinary Iron bottom grate or on a solid fire Brick.

DOUGLAS RUSSELL Hardware Merchant 48 Sholebroke Avenue Leeds Yorks, 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 state-
ment
The object of my Invention is an improved construction of Bottom Grate or
Furnace Bar & consists of a Pan or Trough about one & half inches deep, about
two inches wide & of various lengths made of cast iron or other metal. Into
this trough I fit a fire clay Bar or any suitable cement. A number of these Bars
placed side by side with about half an inch air space between each forms a Bottom
Grate suitable for a Range, stove or Boiler. For ordinary fire places I prefer casting
the Bottom Grate in one piece & consists of an Iron pan about one & half inches
deep with a number of holes or slots at the bottom these slots or holes may have
flanges all round & projecting upwards, the spaces between the flanges I fill with
fire clay or any suitable cement.
The advantages of my invention are as follows—
1st. The fire Brick or cement fitted into metal pans or troughs is much more durable
than not thus fitted.
2nd. The fire burning upon fire Brick having spaces to admit air & also to allow
the ashes to fall through, is much brighter & cleaner than if burning upon an all
Iron bottom grate or on a solid fire Brick.
In order that my invention may be more readily understood & carried into practical
effect, I have hereinto annexed drawings illustrative of my improvement & will now
proceed to describe same with the assistance of the various Figures & letters of
reference marked thereon. Scale about 3 inches to a foot.

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―
1st. Improvement in Bottom Grates & Furnace Bars, substantially as & for the
purposes described.
2nd. A Bottom Grate formed of metal having raised sides, & holes or slots at
Bottom.
3rd. A Bottom Grate formed of metal having raised sides, & holes or slots at
Bottom, with flanges round same, projecting upwards-& filled with fire clay or cement.
4th. A Botton Grate formed of a number of loose troughs having metal sides &
bottoms & filled with fire clay or cement.
5th. A Furnace Bar consisting of an outer case or trough having metal sides &
Bottom & filled with fire clay or cement.
