CLEMENT HAMIL PERROT, Eastwood Lodge, Rotherham, Ironfounder, ARTHUR
HABERSHON, Ferham House, Rotherham Ironfounder, and JOHN CHRISTOPHER
RICHMOND Maltby near Rotherham Model maker do hereby declare the nature
of our invention for IMPROVEMENT IN KITCHEN RANGES WITH RISING BOTTOM GRATES
to be as follows:
-
We claim the making of kitchen ranges with rising bottom grates which are
provided with a rack underneath for the purpose of keeping them in position
when raised up and which are also provided with a hinged lever for releasing this
rack when it is desired to lower the grate.
We append drawings which substantially illustrate our invention. Fig. 1 shews
the grate quite down and Fig. 2 the grate raised upon the first tooth of the
rack.

COMPLETE SPECIFICATION.
Improvement in Kitchen Ranges.
CLEMENT HAMIL PERROT of Eastwood Lodge Rotherham Ironfounder, ARTHUR
HABERSHON of Ferham House Rotherham Ironfounder and JOHN CHRISTOPHER
RICHMOND of Maltby near Rotherham, Pattern maker 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 :-
Our invention, which has been improved upon since our Provisional Specification
was granted, consists of a method of raising or lowering the bottom grates of kitchen
ranges by means of a rack attached to the underpart of the bottom grate and a
ratchet (working through a slit in the fret of the range) which acts a stop for the
rack and also for lowering the same gradually, to the extent of half the distance
between the teeth of the rack, by each successive movement: motion is given to
this ratchet by the insertion into a hole in the lower part of it of a lever, such as
a poker or other suitable instrument, made to fit.
To raise the bottom grate this lever is put between the two middle vertical bars
of the range, into a hole formed on the top of the bottom grate of the same size
as the above mentioned hole in the ratchet, but as to this part of the arrangement
for raising the bottom grate we lay no claim of novelty-To prevent the bottom
grate from being set free by the lowering movement of the ratchet so as to drop
quite down, we make the topmost tooth of the rack more prominent than those
below it when the bottom grate is required to be let quite down, for the removal
of the cinders or otherwise, the ratchet must be raised and brought forward at
the bottom into a groove made for the purpose before being brought forward at
the top. Our invention will be better understood on reference to the accompanying
sheet of drawings in which Figures 1. 2. 3 & 4 are elevation in section.
Fig. 1 shews the bottom grate partially raised.
Fig. 2 shews the bottom grate lowered to the ordinary position.
Fig. 3 shews the position of the ratchet in the act of lowering the bottom
grate.
3
Fig. 4 shews the bottom grate entirely dropped for the purpose of cleaning
and the required position of the ratchet when admitting the grate to be in that
position.

page_text: The same letters refer to similar parts throughout the several views.
A, is the bottom grate.
B, is the hinge on which the same moves.
C, is the toothed. rack.
D, is the ratchet which supports the same.
E, is the hole in the bottom grate for raising it by the insertion of a lever.
F is the holo in the ratchet for the insertion of a lever for lowering the bottom
grate.
G, are stops which catch behind the fret of the range on each side of the ratchet
to prevent its being drawn too far forward.
H, is the 'extended tooth which prevents the bottom grate being lowered too far.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:
о
(1) The arrangement of parts by which the bottom grates of ranges can be lowered
by the ratchet motion substantially as hereinfore described and illustrated in the
accompanying drawings.
(2) The arrangement of a ratchet or catch by which the bottom grates of ranges
can be dropped quite down substantially as described and illustrated in the accom-
panying drawings.
