PROVISIONAL SPECIFICATION.
Improvements in or connected with Fire Grates.
I CHARLES HATTERSLEY, of Rockleigh, Mexbro', in the County of York, Iron
Founder, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to construct fire grates in such a manner that the
draught may be regulated at will, whilst at the same time the parts forming the
said grate are of simple construction.
According to my invention I hinge or otherwise fulcrum a door to the interior
side of the "canopy," which forms the front of the flue, and to the opposite side of
the flue a seat is provided for the door to rest against, when in its closed position.
A rack is attached to the door or to a projection on the door, such rack passing
through a suitable aperture in the "canopy," into the edge of which aperture, the
teeth of the rack take.
By means of a handle on the exterior end of the rack, the door may be adjusted
as required, and the draught regulated to any required degree.
Instead of adjusting the door by means of a rack, it may be adjusted by an
eccentric working below the door, or by any other convenient means to suit the
grate to which my improved regulating door is to be applied.
It will be readily seen that by removing the "canopy" from the other portion of
the grate, the whole apparatus above described is also removed, when it can be
cleaned or otherwise attended to.

COMPLETE SPECIFICATION.
Improvements in or connected with Fire Grates.
I, CHARLES HATTERSLEY, of Rockleigh, Mexbro', in the County of York, Iron
Founder, 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 construct fire-grates in such a manner that
the draught may be regulated at will, whilst at the same time the parts forming my
improvements are of simple construction.
In order that my invention may be clearly understood, reference is given to the
accompanying drawings in which similar letters refer to like parts in all the
figures.
Fig. 1 is a front elevation of a fire grate, shewing my invention applied thereto.
Figs. 2 and 3 are sectional detail views, drawn to a larger scale than the previous
figure.
Figs. 4 and 5 are modifications of my arrangement.
According to my invention I employ a door A, which is hinged or otherwise
fulcrumed at B to the interior of the "canopy" C which forms the front of the
flue D; and to the opposite side of the flue D, a seat E is provided for the door A
to rest against, when in the closed position.
A rack is attached to the door A or it may be attached to a projection on
the door, such rack F passing through an aperture G in the canopy C, into the
edge of which aperture the teeth F of the rack F take. The door A may be

page_text: adjusted as required, by means of the handle H situated on the extremity of the
rack F, and the draught up the flue D is thus regulated to any required degree.
In the arrangement shewn at Fig. 4, I mount a spindle J in the canopy C, and
on the end of the said spindle I mount an eccentric or cam K which bears against
the under surface of the door A. By turning the spindle J by means of the knob
or handle H, the eccentric or cam K raises or lowers the door A as required.
At Fig. 5 a further modification is shewn, in which the handle H is mounted at
the side of the canopy C. This handle H is connected to the door A by means of
a connecting piece passing through the segmental aperture L in the canopy, and
by moving the said handle H the door A may be adjusted to any desired position,
where it may be held by means of any suitable catch, not shewn in the drawings.
If desired, a crank may be attached to the spindle at the exterior of the canopy,
for imparting the required movement to the door A.
By removing the canopy from the other portion of the grate, the whole
apparatus above described is also removed, when it may be cleaned or otherwise
attended to.
Although I have described and shewn several particular manners of carrying my
invention into effect, it will readily be seen that the same may be modified without
departing from the nature of my said invention.
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. The door A hinged to the canopy C, substantially as and for the purposes set
forth.
2. The door A. fulcrumed at B to the canopy C, combined with the seat Ę in the
flue D, substantially as set forth.
3. The particular arrangement and construction of the parts for operating the
door A, as illustrated in Figs. 1 to 5 of the accompanying drawings.
4. The combination of the various parts forming the means or apparatus for
regulating the draught in fire grates, substantially as herein set forth and shewn in
the accompanying drawings, together with any mere modification or modifications
thereof.
