PROVISIONAL SPECIFICATION.
Improvements in or relating to Adjustable Canopies of Stove Grates.
I, THOMAS SWANN GARLAND, of Wharncliffe Works, Green Lane, in the City
of Sheffield, Manager, do hereby declare the nature of my invention to be as
follows:-
The object of my invention is to simplify the construction of the adjustable
canopies of stove grates, and thereby to reduce the cost of manufacture."
I will first premise that these canopies.are pivotted at their top edge to the
front plate of the fire place to enable the upper part of the opening to be closed
or partially closed as desired, and hitherto in casting the various parts it has
been necessary to use cores to produce certain parts such as the recessed
bearings to receive the canopy pivots.
My invention dispenses with the use of cores and core boxes, also the ordinary
canopy pivots, and thus simplifies the work of moulding.
The canopy may be either plain or ornamental, its top edge being curved
over to form a hook with the concave side to the front, and it is provided with
the usual segmental side wings, set back a little distance from the edge.
The hooked top edge is passed through to the back of the front plate between
slots prepared in the edges of the front plate, and is hooked upon a corre-
spondingly shaped convex roll or projection cast upon the back of the front
plate, on which it can turn, as upon a hinge.
The lower edges of the side wings rest upon small bracket pieces which retain
the canopy in any position to which it may be turned upon its hinge.
Small segmental pieces eccentrically placed with respect to the hinge, upon
each end of the hooked top edge, engage with the beforementioned slots, and
prevent the accidental release of the canopy.

COMPLETE SPECIFICATION.
Improvements in or relating to Adjustable Canopies of Stove Grates.
I, THOMAS SWANN GARLAND, of Wharncliffe Works, Green Lane, in the City
of. Sheffield, Manager, 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 chiefly to simplify the construction of those
parts of a stove grate and its adjustable canopy which form the joint upon
which the canopy turns, and thereby to enable such parts to be produced in the
castings with less labour to the moulder, and at less cost than hitherto, and I
am enabled to dispense with a considerable amount of skilled manipulation (or
fitting) when putting the parts so cast together.

parts such as the recessed bearings to receive the canopy pivots.
it has been necessary to use core prints" and "cores
My invention which is illustrated in the annexed drawings dispenses with the
use of cores, core prints and core boxes, also the ordinary canopy pivots, and
thus simplifies the work of moulding.
Fig. 1, is a front elevation of the upper part of a stove grate with the canopy
in position.
Fig. 2, back elevation of same.
Fig. 3, back view of portion of front plate enlarged.
Fig. 4, edge view of same.
Fig. 5, view of one end of canopy enlarged.
Fig. 6, back view of same.
In carrying out my invention as shown, and premising that the canopy A
may be of any suitable design either plain as shown or ornamental as desired,
I curve its top edge to form an elongated hook B, the concavity C being in
the front side.
It is provided with the usual segmental side wings D, set back a little from
the edges E, cast upon the back or inner side of the front plate F, just above
the opening for the canopy, is a horizontal projection, for the hook B of the
canopy A to engage with, to which it may conform in length and shape as a
convex moulding-or (which I prefer) as a flat rib or baffle plate H, with
segmental ends I, which parts fit into the concavity C, the ends forming the
paths upon which the canopy turns as upon a hinge, and the rib preventing the
passage of any smoke, soot, and the like.
The parts marked J, are for the side wings of the canopy to rest upon, and
to retain it at any angle in which it may be turned or adjusted.
The openings K, at the top of the strips I, are to admit the insertion or
withdrawal of the hook B, when the canopy A, is raised to the required height
for the purpose.
I prefer to arrange above the horizontal projection a shelf or ledge M, to
protect the joint from falling dust or soot.
Small projecting pieces Nare to prevent the accidental release of the canopy.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1-In stove grates with adjustable canopies, the construction and arrange-
ment of the canopy hook B, the horizontal projection (forming the joint upon
which the canopy turns), projections N, and retaining pieces J, all co-acting
as herein before described and set forth.
2-In stove grates having adjustable canopies, the novel construction of the
co-acting parts which enables them to be cast without the use of core-prints or
cores as hereinbefore described & shown.
3-In stove grates having adjustable canopies, the construction of the joint,
consisting of an elongated hook B (on the canopy), a support (on the front
plate), having a horizontal central rib or baffle plate H, fitting against the sur-
face of the concavity C, of the said hook B, and provided with segmental ends
or bearings I, in combination with or without a soot ledge M, as herein before
described and illustrated.
