:
An Improvement connected with Lifting Bottom Grates of Ranges
and Stoves.
I THOMAS JOHN CONSTANTINE of 61 Fleet Street, City of London, Manu-
facturer of the Treasure Cooking Range, do hereby declare the nature of my
invention to be as follows:-
This invention has for object, the construction and arrangement of the bottom
grates of ranges and stoves having a rising action from the back simultaneously
with that of the front when raised by the usual lifting and lowering appliances.
For the purpose of my invention I pivot or hinge a frame forming part of the
back portion of the bottom grate on lugs or socket lips formed on the side cheeks.
The frame from which the pivots project leans rather forward towards the bars
of the bottom grate and the upper part is rounded to fit loosely under a shield
when moved.

An Improvement connected with Lifting Bottom Grates of Ranges
and Stoves.
I, THOMAS JOHN CONSTANTINE, of 61 Fleet Street, City of London, Manu-
facturer of the Treasure Cooking Range, 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 relates to a novel construction and arrangement of the bottom
grates of ranges and stoves having a rising action from the back simultaneously
with that of the front when raised by the usual lifting and lowering appliances.
Figure 1 of the annexed drawings is a part sectional elevation of a fire grate
with the bottom grate in its lowest position. Figure 2 a similar view with the
bottom grate in its highest position, and Figure 3 a perspective elevation of
the bottom grate detached.
For the purpose of my invention, I pivot or hinge a frame A forming the back
portion part of the bottom grate B on lugs or socket lips C, C, formed on the
side cheeks D, D. The frame A from which the pivots E, E, project leans rather
forward towards the bars of the bottom grate, and at the upper part at F, the
head is rounded to fit loosely under a shield G when moved.
I form grooves or slots in the head F for ashes to lodge in, this method saves
the head from burning and being distorted by heat.
The bottom grate is liftable from the front by inserting the end of poker
into the pocket H, and it can be temporarily fixed at any desired height by the
paul or tooth of the weighted lever or tumbler I engaging in the serrations Jon
the inner face of the middle bar K of the fire basket, the weight L of the tumbler I
being sufficient to retain the bottom grate at any elevation.
By this invention, a large or a small fire in a range or close stove can be kept
going in the fire basket as desired and poking is unnecessary, because the bottom
grate has only to be lowered a little, and then raised again to give the required
agitation to the fuel for the ashes to fall through.

page_text: It will be observed by the drawings that I provide a dip from just behind the
pivot pin portion to the rear to hold fuel enough for keeping the fire alight when
the bottom grate is lifted to its full height, as at Figure 2.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
•
Pivotting a bottom grate of a range or close stove from below the back end in
lips of the side cheeks as supports, the frame of the pivots being in advance at
the upper part, and with a curved head for moving under a fixed shield,, as and for
the purposes specified and substantially as shown in the annexed drawings.
