Improvements in or connected with Fire-guards or Fuel-economisers
for Fire-grates and Stoves.
We, WILLIAM HENRY HARVEY, of 17 Old Queen Street, Westminster, in the
County of London, S.W., Colliery Agent, and THE INCANDESCENT FIRE MANTEL
AND STOVE COMPANY LIMITED of 53 Victoria Street, Westminster, in the County
of London, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of fire-guards and fuel-economizers or
cinder-guards, and has for its object the furnishing of a ready means of adjusting
or altering the size of the guard or fuel-saver to suit the different sizes of fire-
grates in vogue: thus obviating the necessity of making the guards or framework
in so many gradations of size: since by this invention each guard or framework is
to a certain extent readily susceptible of enlargement or the opposite.
This invention consists
(1) In introducing one or more vertical flutings, corrugations, or bends (of round,
angular, or any section) in the framework or guard, preferably in the centre or at
the sides so as not to interfere with the symmetry of design in the guard: which
Autings or corrugations can be flattened out or compressed, as may be required,
and the width of the guard correspondingly increased or diminished to suit the
size of the fire-grate to which the article is being applied.
(2) In attaching or adding to the sides of the guard supplementary wings or
additions of wirework or other light metal work, which additions are susceptible of
being expanded or compressed as may be required by the size of the fire-grate
to which the guard or fuel-saver is being applied. These wings or additions
may be
(a) In the form of vertical loops of iron-wire or rod, or other suitable
material, bent vertically into a sinuous or serpentine shape, like the
letters and U inverted. By compressing or forcing apart these 'sinuous
bends or loops, the size of the wings can be varied at pleasure. To stiffen
these loops, a double series of bends may be employed, if necessary,
the U-like loops of the one series corresponding with the invert U of
the other.
(b) Or the wings may take the form of an expansible lattice-work structure
on the lazy-tougs principle.
(c) Or they may be constructed so as to slide along horizontal guides affixed
to, or forming part of the structure of, the main framework of the guard.

We, WILLIAM HENRY HARVEY of 17, Old Queen Street, Westminster, in the
County of London, S. W. Colliery Agent, and THE INCANDESCENT FIRE MANTEL
AND STOVE COMPANY LIMITED, of 53 Victoria Street, Westminster, in the County
of London, 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 for improvements in or connected with firegrates and stoves
relates to fire frames or mantels used in connection with firegrates for enabling
coke to be burnt in ordinary fire places and known as incandescent fire mantels,
and has for its object to construct each mantel so that without lessening its strength
and general rigidity its width can be adjusted within certain limits according to
the size of the grate to which it is to be fitted without deteriorating from its
supporting power. This arrangement enables the number of mantels which are
stocked to be considerably reduced to say about one-fifth as by it only about six
different sizes need be made instead of say thirty; and consists in forming the
mantel in such manner that it can be collapsed or cut off to reduce, or extended to
increase, the mantel to the required width.
In the accompanying drawing Fig. 1 is a front elevation of a fire mantel-
constructed according to this invention and showing two forms of side ends one
adapted to be easily cut and the other collapsable, and Fig. 2 is a detail view. In
the arrangement shown in the upper part of Fig. 1 the side ends or extensions a of
the mantel bare formed at their upper parts by extending the wire c of the frame-
work in the form of reverse bends that are rendered rigid by transverse wires d
encircling the vertical wires e as shown in Fig. 2. When it is required to reduce
the width of the frame a portion is cut away through a top or bottom bend along
a line parallel to the interrupted line ..
In the modification shown in the lower part of Fig. 1 the lower side ends or
extensions of the mantel bare formed by extending a wire c of the framework in.
the form of reverse bends that can be collapsed or extended to the required size.
If desired the extensible or collapsable portions may be in the middle of the frame.
Instead of. using the spring of the metal to collapse or extend the frame, one part
may slide or hinge on another part, or the wirework may be arranged at the ends
or other parts to be corrugated in plan so that it can be collapsed or extended.
It will readily be understood that a single construction may extend the full
vertical depth of mantel instead of having two or more different constructions in
the upper and lower parts of the mantel or frame.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be perforined we declare, that what we
claiin is:-
1. In fire or fuel frames or mantels for firegrates and stoves the collapsable
reducible or extensible side ends substantially as described for the purpose
set forth.
2. A collapsable reducible or extensible fire mantel substantially as described
for the purpose specified.

page_text: 3. The improvements in or connected with firegrates and stoves substantially as
described with reference to the drawings.
