Improvements in Grates and Stoves.
I, MALCOLM THOMAS LANDER of 2, Ashbrook Road, Upper Holloway, N.
Hot Water 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 :-
The object of my invention is to provide simple and efficient means whereby the
quantity of air supplied to assist in the combustion of fuel in a grate or stove may
be regulated and controlled with the greatest accuracy.
In carrying out my said invention I provide a controllable valve underneath the
fuel receptacle and a second controllable valve in the smoke flue at the point where
the smoke flue communicates with the grate or stove, and a hinged frame or door
on either side of the grate arranged to close together either in front of the fire or
higher up to enclose the upper part of the opening, this frame to be preferably
glazed with suitable glass to withstand heat. By this means the air supply is
regulated to the fire. The hinged doors are removable up and down the height of
the stove, regulating the draught and acting as a blower.
In order to better explain the details of my invention I append the accom-
panying drawing which represents a section taken vertically through an open grate
fitted with my improvements. A represents the valve controlling the quantity of
air admitted to the bottom of the fuel receptacle. The valve A is fitted to a roller
pivot A carried on brackets or hooks B, which latter are screwed or otherwise
suitably attached to the bottom of the grate.
.
The weight of the roller B is such as to constitute a counterpoise of the weight
of the valve A, so that the valve may be placed in any position according to the
sweep of the dotted line shewn on the drawing, and will remain in any such position
without the aid of any additional fastening or support.
C represents a valve similar in general construction to that previously described,
and is designed to regulate the quantity of air and smoke. passing into the smoke
flue, preventing a down draught and dispensing with the common register door.
The valve C is attached to the roller C¹ carried on hooks or brackets D which
are screwed or otherwise suitably attached to the upper portion of the grate.
A projecting arm E is affixed to the roller C' and protrudes ont beyond the face of
the grate so as to afford ready means of moving the valve without soiling or burning
the hand. The whole of this valve is also balanced in point of weight so that it
will remain in any position indicated by the sweep of the dotted line without
further support or fastening. The hinged frames acting as the blower are marked
with the letter F and the dotted lines show the highest position to which they can
be moved. These hinged frames may be worked upon a rod or rack, or may be
hinged on to projecting hooks.
It will be readily seen from the said drawing and the foregoing description that
I am by means of my invention able to control. with the utmost accuracy the
amount of air supplied to and taken away from the fuel, and can consequently
regulate the rate of combustion, or what is commonly termed the "draught " of
the grate or stove.
Having now particularly described and ascertained the nature of my said inveu-
tion, and in what manner the same is to be performed, I declare that what. I
claim is :-

constructed and operated, substantially as described and for the purposes specified.
(2.) An improved means for regulating the draft in grates and stoves, consisting
of a balance valve or flap fitted to the top of the fire-place or stove and controlling
the smoke flue at its lower end, substantially as described and shown and for the
purposes specified.
(3.) An improved means of regulating the air supply to grates consisting of
hinged doors on either side of the fire-place, capable of being raised and lowered
controlling the air supply substantially as described and for the purposes specified.
