An Improved Apparatus to be Inserted in Chimneys, Chimney Pots,
and the like, for Providing an Ascending Current of Air to Carry
Off the Smoke from Domestic Fires, and to Prevent Down
Draught.
"
I, CHARLES HITCHCOCK, of 19 East Street, Manchester Square, in the County
of London, Builder, 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 an improved apparatus to be inserted in chimneys,
chimney pots and the like, for providing an ascending current of air to carry off
the smoke from domestic fires and to prevent down draught, which consists of one
or a series of trumpet shaped tubes fixed at the base or in any other part of a
chimney for the purpose of forming an up draught.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a front view of the trumpet shaped tube.
Fig. 2, is a side view fitted to a chimney.
In carrying my invention into practice, I construct a trumpet shaped tube a with
a bell-shaped opening at the bottom and a small bend e at the top, this said bend e
is provided with a tubular spigot f which is inserted in any chimney.' At or near
the base of the trumpet shaped tube a I provide a tab or strap c for the purpose of
fixing the trumpet shaped tube a to the chimney b by a bolt or rivet d.
The aforesaid trumpet shaped tube a and bell-shaped opening 1 with the top
bend e may be constructed of any suitable shape and from either metal, earthenware
or of any other material.
This trumpet shaped tube herein before described may be fixed to any existing
chimney constructed of stone, bricks, or metal, and placed in any position where it
is required to perform its proper function.
If preferable I may fix to a chimney one or more of the trumpet shaped tubes
and the said tubes may be fixed in any suitable position, or they may be attached
to a special made chimney.
The object of my invention is to carry away smoke when fixed to a chimney.
carried up above the top of houses.
Arrows indicate the direction taken by the up draught.
The trumpet shaped tube a may be fixed in or on a chimney either upright,
obliquely or otherwise.
It will be understood that the foregoing is given by way of illustration, and that
the shapes materials and proportions of the parts may be varied in many ways
within the scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In an apparatus to be inserted in chimneys, chimney pots and the like, for
providing an ascending current of air to carry off the smoke from domestic fires,
the combination of two or more trumpet shaped tubes with bell-shaped openings at
the bottom and a bend at the top with a tubular spigot, substantially as herein
described and according to the accompanying drawing.
2. In an apparatus to be inserted in chimneys, chimney pots and the like, for
