JOHN WOOLVEN of 1 Newmarket Road, Lewes Road, Brighton Sussex, WILLIAM
EADE of 49 Wordsworth Street West Brighton Sussex, in Partnership as Jobbing
Builders do hereby declare the nature of our invention for THE INCREASING OF
UP DRAUGHT IN SMOKY CHIMNEYS, AND ECONOMISING HEAT to be as follows:-
The Stoves and Ranges to be Portable or fixed with Circular flues Vertical or
horizontal. The Stoves and Ranges will have partial funnel shaped flue directly
over fire, with door to open into main shaft for the purpose of increasing or
decreasing draught, and for Sweeping main shaft, the door to be raised or lowered
by means of small chain upon barrel with two Cog wheels at right angles fixed to
inside of front of stove at top, to be worked by handle and Spring upon the outside
of Stove. The flue.will decrease from entrance and bend easily to front to pass
down and across hearth line to and up opposite side on face of Stove or range and
to repass entrance with short continuation up main shaft.
There will be two Soot doors, one on each side of horizontal portion of flue that
passes across hearth to enable the flue to be swept by ordinary wire brush, also
the continuation up main shaft to be fitted in Socket to allow of being taken off.
for Sweeping there will not be any brickwork setting required. The soot will fall at
back to base of Stove or range, a space with opening being provided at base for
sweeping out soot, the opening to be covered with plate level with horizontal.
portion of flue and under fire in open ranges the flue will encircle oven and boiler,
the base of oven and boiler to set on top of flue that passes across and upon hearth.
The Portable stoves and ranges would be single or double with stout separation
back. The door before mentioned that would open into main shaft when closed.
would increase the draught in circular flue, and when open would decrease the
draught in circular flue by passing the Smoke up main Shaft.
