I, HARRY HUNT, of Newington Green, in the County of Middlesex, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of kitchener; and relates, more
particularly, to adjustable bottom grates, and to a method by which the kitchener may
be worked with either a closed or an open fire.
In kitcheners, the bottom grates of which are made adjustable in point of height,
it frequently happens that in consequence of a pivot forming an integral part of the
mechanism by which such adjustability is effected, being exposed to the heat of the fire,
such pivot is quickly destroyed thereby.
Now, according to my present invention, I provide a frame which supports the fire-
grate, and is adapted to be moved up or down by means of a handle which projects in
front of the kitchener, which handle is provided with a suitable detent by means of
which the said frame can be fixed at any desired height.
A loose bottom grate is provided which fits upon the frame described above, and is
easily removable; and can, therefore, in the event of being burnt away, be replaced
by another in a few moments.
A double link device is provided under the said frame. One extremity is pivotted
to the frame, and the other to a convenient point at, or upon, the floor-level, preferably
to the front of the ash pit; so that when the frame is raised or lowered, the link opens
or closes in following, and steadying, the motion thereof.
For the purpose of adapting a kitchener to be worked with either an open or a
closed fire, I form a flap in a projecting part of the back coving, which flap extends
downwards to about the level of the hot plate. This flap is furnished with two cheeks
which are concealed within the flue behind the flap when the latter is down, i.e., flush
with the coving; but, when the flap is turned upwards on its hinge, it, with two
further flaps which are connected to it by an equal number of links, together with the
cheeks, forms an open flue extending from the hot plate to the coving; the whole
forming a hood up which the smoke from the fire will draw so soon as the fire cover
is taken off.

page_text: 1, HARRY HUNT, of Newington Green, in the County of Middlesex, 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 an improved construction of kitchener, and relates more!
particularly to adjustable bottom grates, and to a device by means of which the kitchener
can be worked with either a closed or an open fire.
In order that the invention, and the means by which it is to be carried into practical
effect, may be thoroughly understood, I will proceed to describe the same in detail,
referring in so doing to the accompanying drawings, which are to be taken as part of
this specification, and read therewith.
Fig. 1 is a sectional side elevation on the line Y-Z of Fig. 2.
Fig. 2 is a front elevation of the ash-pit, range, and smoke-flue.
Fig. 3 is a detail front elevation, and
Fig. 4 is a detail plan.
It has sometimes been the practice to place the pivot by which the bottom grate is
connected to the raising and lowering mechanism close to the said bottom grate with
the result that the said pivot has been quickly burned away, thereby necessitating a
renewal to the extent of bottom grate, pivot, and the link or lever connected
thereto.
Now, according to my present invention, the bottom grate is made separate from the
raising and lowering mechanism, and has no pivotal device formed upon it, neither is
there one close to it.
A is the bottom grate, and a, a, lugs formed on the underside thereof.
They are sufficiently long to pass through a frame, B, to which the grate is made
fast by pins, b, driven through the lugs, a.
When the grate, A, has been burnt through, the pins, b, are driven out, and a new
grate fixed, before the frame has been attacked by the fire.
This frame has a handle, C, formed upon it which projects through the range, D;
and is adapted by means of a detent, d, to engage with a rack, E. I do not confine
myself to the type of handle illustrated in the figures, inasmuch as any other suitable
kind, e.g., a socket capable of receiving a poker-end may be used.
F is a double link. One end is pivotted at, f, at or upon the bottom of the ash-pit;
and the other at, g, to the extremities of rigid projections g', g', depending from the
underside of the frame, B.
The length of the projections, g¹, g', suffices to keep the pivots out of the reach of
the destructive influence of the fire.
The full lines of Fig. 1 indicate the lowest, and the dotted lines the highest, position
of the bottom grate.

page_text: The second part of my invention relates to a device by means of which a kitchener
can be used with either an open or a closed fire.
H is the smoke flue; and, h, the seat of the central and movable part of the hot
plate."
-
I is the flap, hinged at, i, to the front of the smoke-flue, or of the back cove. This
flap is provided with cheeks, j. I provide a second pair, j¹, pivotted at k, and connected
with either the flap, I, or the cheeks, j, by links, l.
M is a flap adapted to control the flue, m; and, n, a detent for holding the bonnet
up in the position illustrated in Figs. 1 and 2.
The method of using this second part of my invention is as follows.
If the kitchener is to be used with an open fire, the flap, I, is pulled up into a
horizontal position, when it and the two pairs of cheeks j, j¹, will form a bonnet
extending from the smoke-flue, H, down to the hot plate on each side of the fire.
The dotted lines of Fig. 1 shew the relative positions of the several parts of the
bonnet described above when it is in process of being extended.
After the bonnet has been so extended, the flap, M, is pulled forward into the
position indicated by the full lines, for the purpose of closing the flue, m, and so
stopping communication between the fire and smoke-flue other than by way of the
bonnet.
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 :-
1. The combination of bottom-grate, adjustable frame and handle adapted to receive
the said grate and to raise or lower it into any given position, projections from the
underside of said frame, and pivotal connection of said projections to a link device,
substantially as and for the purpose set forth.
2. The combination of flap pivotted to the smoke-flue or to the back-coving, cheeks
projecting from.said flap and cheeks pivotted at the level of the hot-plate, and a link
connection between the cheeks projecting from the flap and those pivotted at the level
of the hot-plate, said combination adapted to form an expanding and contractible
bonnet from the hot-plate to the smoke-flue, substantially as set forth.
