An Improved "Blower" for Domestic Fire-grates.
1, CHARLES LAKE, of 7, Suffolk Lane, Cannon Street, London, E.C., Stationer,
do hereby declare the nature of this invention to be as follows:--
My Invention relates to a "blower" for domestic fire-grates. The said "blower "
consists of a sheet of metal of such dimensions and shape as to close the open front of
the grate above the bars and adapted to make a practically airtight contact around
its edge with the front plate of the grate to prevent access of air above the fire, the
plate being of such light construction that it may be held up in position merely by
resting on the top bar if necessary and by the difference of atmospheric pressure on
its two faces caused by the draught of the chimney. The "blower" is provided with
a handle by which it may be applied to, and reinoved from, the grate, said handle
being secured to it through a non-conducting material which will prevent transmission
of heat to the handle.
Dated this 30th day of November 1889.
COMPLETE SPECIFICATION.
An Improved "Blower" for Domestic Fire-grates
I, CHARLES LAKE, of 7, Suffolk Lane, Cannon Street, London, E.C., Stationer,
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:-
My Invention relates to a "blower" for domestic fire-grates.
I have illustrated an example of my improved "blower" in the accompanying
drawings forming part of this specification and will describe it with reference thereto.
Figure 1 is a face view, and figure a cross section, of the "blower." The same
letters of reference apply to both figures.
The "blower" consists of a thin sheet of metal A corrugated to give it the necessary
stiffness and improve its appearance and stamped up in one with a marginal frame
or bead B corresponding in shape to the front aperture of the grate above the bars
and of such dimensions that the "blower" when applied thereto will cover the said
aperture, the frame or bead making a sufficiently air-tight contact around its edge
with the front plate of the grate to prevent access of air above the fire.
The "blower" is of such light construction that it will be held up in position
merely by the difference of atmospheric pressure on its two faces caused by the
draught of the chimney. Or, it may also be supported by resting on the top bar of
the grate, if necessary. The "blower" is provided with a handle C secured to it
through a non-conducting material which will prevent transmission of heat to the
handle.
The form of the "blower" would, of course, be varied to suit the aperture of the
grate to which it is to be applied; but the essential feature of the "blower" is that,
although wholly removable, it requires no attachment whatever to the grate, being
held up in position merely by the action of the draught and being, therefore, readily
applicable to any grate of corresponding shape, without special fittings or attach-

tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
The herein-described "blower" for domestic fire-grates, substantially as specified.
Dated this 10th day of January 1890.
