page_text: I, JOHN CAIRD PARKER, of 33 Kenmure Street, Pollokshields, in the County of
Renfrew, North Britain, Ironmonger, do hereby declare the nature of this Invention
to be as follows, that is to say :-
My said Invention has for its object to construct certain parts of cooking ranges in
an improved, simple, and convenient manner and so that the size of the firebox or
grato may be varied.
In carrying out my Invention I make the bottom of the grate movable vertically,
the said bottom being all in one piece or as I prefer having a detachable grating
held in a frame. The grate bottom or its frame is made with bars extending
downwards from it and the bottoms of these bars are jointed to lever pieces or
cheeks which are made in one piece with a front plato which closes the space
beneath the grate space except at its top which is flared or inclined outwards to
catch ashes falling from the front of the grate. The combined cheeks and front
plate is made with pins projecting from its side to be entered into notches or open
centre sockets formed in the framing of the range. The front plate can be turned
on the pins as centres and when turned the cheeks raise or lower the grate bottom as
required. One of the cheeks is made with ratchet teeth or notches with which a
movable detent can be engaged to hold the parts in any desired position. The inside
of the grate space is made so that the grate bottom can be moved up and down in it;
and the grate bottom and front plate can be entered into their places or removed
without taking down any other part of the range.
Dated this Third day of March 1888.

page_text: I, JOHN CAIRD PARKER, of 33 Kenmure Street, Pollokshields, in the County of
Renfrew, North Britain, Ironmonger, 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, that is to say :-
My said Invention has for its object to construct certain parts of cooking ranges in
an improved, simple, and convenient manner, and so that the effective size of the
firebox or grate may be varied.
A cooking range as provided with my improved apparatus is shown on an accom-
panying sheet of explanatory drawings, figure, 1, being a sectional plan, and figure, 2,
a front elevation of part of the range, figures, 3, and 4, are vertical sections as at right
angles to the front of the range, the parts for varying the effective size of the firebox
being shown in different positions in the two figures. In these drawings the same
reference letters are used to mark the same or liko parts wherever they are repeated.
In carrying out my Invention I make the bottom of the firebox or grate, A, movable
vertically, the said bottom being all in one piece, or, as I prefer, having a detachable
grating, B, held in a frame, C. The grate bottom or its frame, C, is made with bars
or legs, D, extending downwards from it at the sides, and the bottoms of these legs,
are jointed to levers, E, or cheeks which are made in one piece, with a front plate, F.
This plate, F, closes the space beneath the grate space except at its top, G, which is
flared or inclined outwards to catch ashes falling from the front of the grate. The
piece comprising the cheeks, E, and front plate, F G, is held in its place by pins, H,
entered through holes in the cheeks, E, into holes in the side plates, J, which
separate the ovens or side spaces from the middle compartment of the range; and
these pins, H, act as contres on which the piece, E F G, can be turned. The grate
bottom or frame, C, is guided between the front, K, of the firebox and ribs, L,
formed or fixed on the side plates, J; and it is made or fitted so as to move easily
up and down. The grate bottom, B C, is shown in its lowest position in figure, 3,
the front plate, F G, being then in its innermost position, and the grate bottom
can be raised so as to diminish the fire space, A, more or less by turning the front
plate outwards when the checks, E, acting as levers on the legs, D, of the grate
frame, C, raise that frame up. One of the cheeks, E, is made with ratchet teeth, M,
with which a movable detent or catch, N, can be engaged to hold the parts in any position,
this detent having to be lifted clear of the ratchet teeth when it is wished to lower
the grate bottom. The grate bottom is shown in its highest position in figure, 4.
The front plate and cheeks, G F E, with the grate bottom, B C D, can be entered
into their places or removed without taking down any part of the range. If preferred
the upper part, G, of the front plate may be made stationary and separate from the
lower part, F.

page_text: 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 :-
The improved combination of parts for varying the size of the fire space of a
cooking range and comprising a vertically moving grate bottom having side legs
jointed to side cheeks formed on or fixed to a plate extending across the front of the
space below the firebox and centered on pins in plates at the sides of the space,
substantially as hereinbefore described.
