Improvements in Kitchen Ranges.
I, GEORGE FREDERICK WILLIAMSON of Midland Foundry, Wellingborough
in the County of Northampton, Engineer and Iron Founder do hereby declare the
nature of this invention to be as follows:-
:-
These improvements relate to the formation of the fire-place or fire-basket of
kitchen ranges and to the fitting of the table usually fitted in a manner to be
removable from the range.
The object of my invention is to make the various parts so as to be securely held
in position as required without the employment of screws or rivets for fixing, the
parts of the fire-place or fire-basket being made to interlock one with the other
and the removable table being made to be held in position or to be dropped
down vertically when not required for use instead of being necessarily entirely
removed.
I make the range with suitably recessed projections at the rear of the front plate
to receive the side cheeks of the fire-place or fire-basket which are each provided
with a hook at their upper part and a projecting plug at their lower part; both the
hook and plug being part of the casting forming the side check. When the side
check is hooked into the recessed projection provided to receive the book it drops
into position for its plug to enter horizontally the lower recessed projection made to
receive it.
The side cheeks are provided with an inclined slot at the rear end of the check
open at the upper part and extending nearly to the bottom of the cheek. This
slot in the case of ranges provided with rising bottom grates may receive the
trunnions of the bottom grate to rest in the lowermost part of the slot. The
inclined back for the fire-place or fire-basket is made in the form of a plate having
webs thereon at one side to keep the side cheeks of the fire-place or fire-basket the
required distance apart and projecting flanges at the outer side edges to confine the
side cheeks and prevent them from receding from each other beyond the distance
assigned to them by the inner webs hereinbefore mentioned. In order that such an
inclined back may be withdrawn and replaced without disturbing the hot plate of
the range remove part of the material for more than half the depth of the
inclined back between the inner web and the outer flange at each side and I provide
a plug protruding from the lower end of each of the outer flanges. By this arrange-
ment the inclined plate may be introduced to its position horizontally till the plugs
drop into the slots of the side cheeks and the removed portions of the inclined back
allow for a tumbling movement by which the inclined back drops into position.
The said plugs are arrested at the bottom of the slots in the side checks upon the
trunnions or immovable projections from the bottom grate and thus they keep the
inclined back supported without resting upon the bottom grate, allowing the bottom
grate free movement in the case of a bottom grate pivoted at the back of the
fire-place or fire-basket in a manner to allow for raising and lowering the bottom
grate.
I make the removable table with trunnions and brackets formed thereon the
brackets being part of the cast table and the trunnions being wrought iron pins
cast in position or otherwise fitted thereto. Upon the range in any convenient
position usually below the oven door I provide two brackets each having two open
detents or bearings suitable to receive the trunnions of the table. These open
detents or bearings are distanced from the front of the range so that when the
trunnions of the table engage in the nearest pair, the brackets cast upon the table

page_text: bear against the front of the range maintaining the table in a horizontal position;
but when the trunnions of the table are made to engage in the furthest pair the
table drops and hangs suspended against the range being then conveniently out of
the way and therefore not needing to be completely removed from the range. Or
the same result may be attained by making the brackets on the range wide enough
apart to allow of a lateral movement of the table upon its trunnions an inclined
guard plate being provided to prevent such movement taking place excepting by
first elevating the table beyond the horizontal position so that the bracket upon
the table may pass the inclined guard plate on one side of which there is sufficient
clearance to allow the table to drop from the horizontal position to hang vertically
out of the way in the manner hereinbefore described.

COMPLETE SPECIFICATION.
Improvements in Kitchen Ranges.
I, GEORGE FREDERICK WILLIAMSON, Engineer and Iron Founder, of
Midland Foundry, Wellingborough in the County of Northampton, 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 :-
This invention for improvements in kitchen ranges relates to the formation of
the fire-place or fire-basket of kitchen ranges and to the fitting of the removable
table usually situated under the oven door; and has for its objects to make the
various parts of the fire-basket to interlock one with the other so as to be securely
held in position as required without the employment of screws or rivets for fixing,
and to support the reinovable table so that it can be held in position or dropped
down vertically when not required for use.
In the accompanying sheets of illustrative drawings
:-
Figure 1 is a sectional end elevation of a kitchen range constructed according to
this invention and having a movable grate.
Figure 2 is a side elevation partly in section and Figure 3 is a front elevation of
the same.
Figures 4 and 5 are detail view of the cam for raising the movable grate as
desired.
Figure 6 is a part sectional plan of the same.
Figures 7, 8, 9, 10, 11, 12 and 13 are detail views of the detachable parts of
which the fire-basket is formed and
Figures 14, 15 and 16 show a modification of an arrangement of the drop table.
The side cheeks G of the fire-basket at their front ends are cach provided with a
hook at their upper end and with a projecting plug w at the lower end, both the
hook and the plug w being an integral part of the casing forming the side
check G and are received in projecting pieces uu¹ cast on the rear of the front
frame P, the hook e taking into the recessed projection u, and the plug w entering
horizontally the recessed projection u¹.
a
The side cheeks Gat their rear ends are each provided with an inclined slot .c
open at the upper end and extending nearly to the bottom of the check as shown.
The inclined back H for the fire-basket is made in the form of a plate having on
the front face webs y on either side to keep the side cheeks G the required distance
apart and on its back projecting flanges z on either side to confine the side cheeks
so as to prevent them from receding from each other beyond the distance assigned
to them by the inner webs y.
In order that the inclined back can be withdrawn and replaced without dis-
turbing the bot plate J it is provided with openings K and plugs L so that it can

page_text: be introduced to its position horizontally as shown in dotted lines in Figure 12 till
the plugs L drop into the slots of the side cheeks G and the openings K in the
inclined back allow for the tumbling movement by which the inclined back H drops
into its required position.
The bottom grate A is provided at its rear end with trunnions a which rest in
the lowermost part of the slot a:. The front end of the grate A is provided with
ears on which are pivotted lugs or rollers as shown in Figure 7 and 8 bearing
on the front of the flanges i formed on the side of the front casting D. As shown
the bottom grate is adapted to be rotated about the trunnions a by means of the
stepped cam B to raise or lower the grate, the lowering of the grate being positively
assured by the crank pin n in the cam which bears on a loose chain p fastened at
one end to the cam B by the screw and at the other end by the staples to the
grate A. Also in order to allow of this motion the front bars are made in a single
casting D pivotted at the top to the front frame P so that as the bottom grate A is
raised the casting Dadapts itself to this movement. The range is also shown provided
with a front rising table E hung upon the lugs y pivotted to the cars h in the grate A
so that it is raised with the grate A and is approximately horizontal as the lugs g
are retained approximately vertical by the Hanges. The projections on the
table E bear against the lugs g to prevent the table from dropping and are shaped
to prevent the table being accidentally knocked off.
The drop table M. is provided with trunnionsj to engage in the indents 1 and 2
formed in brackets secured to the front plate F; when engaging in the indents 1
the drop table M stands out horizontally, the lugs 7 bearing against the front
plate F of the range below the centre of rotation; but when engaging in the
indents 2 it is free to rotate without the lugs 7 coming into contact with the front
plate F and hangs down out of the way without necessitating its removal.
In the modified arrangements shown in Figures 14, 15 and 16 the drop table M
is carried in bearings 3, 4 in such manner that it can be moved laterally. In the
one position it is held horizontally the lugs 7 bearing against the projections 5 on
the front plate F.
In order to cause the table M to hang down out of the way it is elevated
as shown in dotted lines in Figure 15 so that the lugs 7 are free of the guard
pieces 6 cast on the side of the projections 5 and is then moved laterally so that
the lugs 7 are free of the projections 5 and dropped into the position shown in
Figure 16.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a kitchen range the construction of the fire-basket in separate parts
arranged to interlock one with the other so as to be securely held in position the
whole substantially as described.
2. In a kitchen range a drop table carried in brackets carried on the front plate
and adapted to retain the table in a horizontal position or to allow it to fall into a
vertical position.
3. The arrangement and construction of a fire-basket of a kitchen range sub-
stantially as described with reference to Figures 1 to 8 of the drawings.
4. The arrangement and construction of a drop table for kitchen ranges sub-
stantially as described with reference to Figures 1 to 3 or Figures 9, 10 and 11 of
the drawings.
