I WILLIAM BIRD REDISH of 39 Fielding Street Liverpool in the County of
Lancaster Grate Manufacturer, do hereby declare the nature of this invention to be
as follows:-
The object is to provide for general purposes and for heating ovens and like
chambers a fire grate so made that the combustion of the fuel shall be conducted
without waste and the heat given off by combustion fully utilized.
. Under the first part I combine with the fire bars of any ordinary grate or with
special fire bars a fixed or movable bottom serving also as an ash pan and a back
baving from front to rear and from bottom to top two or more surfaces of inclination
or steps. The ash pan bottom has a flared opening to the rear, and the space
between the back and fire bars leading to the ash pan bottom is contracted by bars
or plates when necessary.
Under the second part 1 combine with any ordinary kitchen range fire grate, or
with a grate constructed as above set forth so as to form a continuation thereof, fire
bars pivotted to suitable carriers and with their free ends extending beneath the oven
or chamber to be heated. There is an ash pan beneath the said fire bars either
secured thereto and capable of being oscillated with the said fire bars or separately
pivotted.
Levers arms or other suitable means are provided for actuating the bars.

what manner the same is to be performed; to be particularly described and
ascertained in and by the following statement :-

DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 are vertical sections at right angles to each other of a fire grate and
oven constructed in accordance with my invention.
Under the first part a are firebars, 6 fixed bottom serving as an ash pan the
bottom b may be made movable if desired. cc blocks forming the back of the fire
place; the surface of the block c is in a different plane to that of the block c¹ thus
forming a projection or break at d which serves to agitate the burning materials as
they descend. When a quantity of ash has accumulated on the bottom b it is pushed
through the opening e which is flared to allow of free egress of the ash on to the hearth
or into a receptacle. The lower edge of the block c is preferably brought so far
forward as to contract the passage between it and the bottom b. Separate bars or
blocks may be used for this purpose.
Under the second part f fire bars pivotted at to a bar h, the bar h extends to the
front of the range and is provided with a rack i into the teeth of which a pawlj fall
so that the grate f can be raised and held up when the oven is not being used as shewn
by the dotted lines. When the oven is to be used the grate fis lowered and fire is
pushed onto it from the ordinary fire place k. is an ash pan underneath the grate f
serving also as a damper by being pivotted at m. The said ash pan might be attached
to the bar h. n oven.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First. The combination of the bars a. bottom b and back c c¹ substantially in the
manner and for the purpose set forth.
Second. The combination with an oven and grate of pivotted fire bars having
actuating devices and an ash pan 7 substantially in the manner and for the purpose
set forth.
