Currall at the Office of the Commissioners of Patents, with their
Petition, on the 6th May 1869.
We, WILLIAM BENNETT, of Aston, near Birmingham, in the County
of Warwick, Builder, and JOHN CURRALL, of Birmingham, in the
County of Warwick, Kitchen Range Fitter, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN KITCHEN RANGES," to be as
follows:-
Our Invention consists, firstly, in giving to the bottom of the grates
of kitchen ranges a rising and falling motion by means of a vertical
screw, which also raises and lowers the ash pan at the same time. The
screw is worked by a moveable key, and the screw box, which is raised
and lowered by the action of the screw, supports the bottom of the grate.
The top of the ash pan forms a rest or table, upon which anything can
be supported. The ash pan can be introduced into its place and with-
drawn by a sliding horizontal motion.
Our Invention consists, secondly, in giving to the bottoms of the
grates of kitchen ranges a rising and falling motion by means of racks

page_text: on the sides of the grate, with which racks the bottom of the grate
may be made to engage by pulling it forward and then raising or
lowering it to the required height. A projecting frame capable of
being temporarily fixed to the bottom of the grate may be used for
raising or lowering it. The said frame also forms a shelf.
Our Invention consists, thirdly, of a box or hollow chamber placed
on the top of the "fall bar" of the grate. This box is perforated with
holes, and when the grate is used as a close fire-grate the air passing
through the said holes is so diffused as to effectually prevent the
formation of smoke.
Our Invention consists, fourthly, of the following arrangement of
the parts of a kitchen range for cottages and small houses. The range
consists either of an oven on one side of the fire-place and a boiler on
the other, or an oven on each side, or an oven only on one side with a
sham oven on the other side. In order to carry the heat in the required
direction we employ a loose fitted and moveable channel or flue passing
in front of the range from one side to the other just below the bottom
of the oven or ovens. We make the fire pass over the top of the
oven, down the side, and under the bottom, then through the said
flue under the bottom of the oven or boiler on the opposite side of the
fire-place and up the back passing through the damper.
Our Invention consists, fifthly, of a rising and falling dust preventer,
serving also as a stand or table, which is provided with projections at
top capable of engaging in the racks herein-before described for raising
and lowering the bottom of the grate.
Our Invention consists, lastly, of a draw plate or blower, somewhat
similar to the ordinary draw plate in form, but provided with a button
or turn, by which it can be fixed to the back plate of the grate. By
means of this turn or fastening the draw plate can be used in the
ordinary or in an inverted position, so as to determine a greater or less
amount of draught.
Our several improvements are applicable both to close and open fire
kitchen ranges.
