Terminals for Chimneys, Ventilating Shafts, and the like.
I, GEORGE FRANCIS VERINI, Proprietor of Zetland Hotel, Saltburn-by-the-
Sea, in the County of York, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object an arrangement of chimney or ventilator terminal
so contrived that the wind shall itself debar its entrance into the chimney and shall.
open abundant provision for the escape of smoke and effluent gases and keep open
that provision on the side of the chimney which is not exposed to the wind.
I make my chimney pot of round polygonal or other shape and closed at the top
either permanently or by a lid that will open for the sweeps brush & close again on
the latter being withdrawn. All round the circumforence I cut out vertical rect-
angular doorways (they can be other shapes if desired) and I hinge to the top of each
doorway a door covering the doorway. Between each door & the next I place a
radial projecting plate so as to protect the doorway from side wind and direct the
wind against the door. The doors or shutters are even in number and each attached
by links or rods to the one opposite in such manner that as one door is shut the other
door is obliged to be open at an angle say of 30° to 45°. The doors can be of
flexible metal and close like a spring or be hinged and are preferably buffered with
should have a
india rubber projections. If it is desired for the sweeps brush that
complete passage up the centre of the chimney pot or terminal the links can be placed
partly up the door be attached to the sides and be curved outward beyond the parts
that have to pass through the doorways so as to leave a clear circular passage in the
centre.

Terminals for Chimneys, Ventilating Shafts, and the like.
I, GEORGE FRANCIS VERINI, Zetland Hotel, Saltburn-by-the-Sea, in the County
of York, Hotel Proprietor, 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 has for its object an arrangement of chimney terminal, or ventilator,
so contrived that the wind shall itself debar its entrance into the chimney, at the
same time providing for the escape of the smoke etcetera, from the sides thereof which
are not opposed to the wind.
The chimney top may be round, polygonal, or other shape closed at the top per-
manently, or by a lid that can be opened to clean it out if necessary.
The accompanying drawings describe the most improved form known to me of
carrying my invention into effect.
Figure 1 is a perspective view.
Figure 2 the plan.
In these A is the chimney shaft, B a horizontal annular plate fixed thereto,
C, C, pairs of parallel gusset plates attached to the shaft A and plate B, D doors
hinged to the gusset plates or to the shaft. The shaft between the gusset plate is
cut away behind the doors, and may be, if desired, flattened where the door hinge
comes, so as to make a moderately tight joint. E, E, are two rods or links, connecting
opposite doors, so arranged as regards length that when the one door is shut, the
opposite one must be open. G, G, are stout cross bars fixed to the shaft below the
rods E, to prevent the sweep's brush from injuring the latter.
The mode of action is as follows:-
The wind blowing in the direction of the arrow closes the door or doors with which
it comes in contact, so as to completely stop the wind from entering the shaft, and
opens the opposite one; the open doors are completely shielded sideways from the
wind by the gusset plates and there is free egress for the smoke, (the doors standing
preferably at 45 degrees with the horizontal)-b-between the plates B and the two
gusset plates. The wind passing these latter causes an induced current outward from
the chimney shaft. The doors, instead of being hinged, can be attached by metal rods
inserted into opposite gusset plates as shown. To prevent noise I attach a flexible
projecting metal loop to the top of the inside of the shutters; just before the shutter

page_text: closes, this loop will come in contact with another similar loop projecting from
the top rim immediately above it.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The arrangement of chimney pots or other exit terminals, ventilating shafts, and
the like, substantially as herein described.
