Fireplaces.
I, WILLIAM SCOTT MORTON, of Albert Works, Tynecastle, Edinburgh, in the
County of Mid Lothian, North Britain, Decorative Architect, 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, that is to
say:
My said Invention has for its object to provide domestic or similar fireplaces with
an improved arrangement of blower or draught plate by means of which the
current of air entering the fireplace can when required be concentrated to act more
exclusively on the fuel in the grate than at ordinary times so as for example to
expedite the incandescence of the fuel when the fire is first lit.
My Invention is by preference applied to the kind of fireplace known as a slow
combustion grate but is also applicable with slight modifications to other forms of
fireplaces. It consists in arranging a plate so that it can slide up and down at the
inner side of the front plate of the grate, such plate having connected to it con-
venient appliances for lowering it when it is required to act as a blower or draught
plate, whilst at other times it may be raised wholly behind the upper part of the
front plate of the grate. Or the plate may be adjusted in any intermediate position
for the purpose of regulating the ingress of air.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing my improvements as applied to a slow
combustion fireplace.
Figure, 1, is a front elevation showing the blower or draught plate in its lowest
position. Figure, 2, is a front elevation with the upper part of the front plate
partly removed and showing the blower in its highest position. Figure, 3, is a
transverse vertical section, and figures, 4, and 5, are horizontal sections. In these
drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
The grate, 6, has a front plate, 7, the upper part of which is by preference made
with an ornamental design and behind this plate, 7, a plate, 8, is fixed between
which two plates, the plate, 9, intended to act as a blower is guided. The guides
are continued down to the top of the fire bars, 10, by fixing a piece of angle iron, 11,

page_text: on each side of the front plate, 7.
A
One end of a chain, 12, is attached to the
middle of the top of the blower, 9, and passes upwards and over a pulley, 13, then
round another pulley, 14, its other end being attached to the inner end of a
lever, 15, which works in a slot, 16, in the top of the front plate, 7. Pins or anti-
friction rollers, 17, are attached to this lever, 15, and arranged in pairs to work
one above and the other below, one pair on each side of the front plate, 7.
catch, 18, is jointed to the front end of the lever, 15, to engage in notches formed
on each side of the slot, 16, in the front plate, 7. The catch, 18, is made with a
handle, 19, for engaging and disengaging it and for moving it along so as to raise
or lower the blower, 9, and a spring, 20, is fixed to the back of the handle, 19, and
arranged to press against the front plate, 7, so as to hold the catch, 18, in any one
of the notches in which it may be placed.
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
The arranging of a blower or draught plate so as to be adjustable vertically at
the inner side of the front plate of a grate or fireplace substantially in the manner
herein before described.
