Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
CHIMNEY POTS OR TERMINALS to be as follows:-
This invention is for the purpose of effectually preventing down draughts and
creating greater up draughts in Chimneys.
A tube or pipe having a hollow jutage of smaller size projecting through its side
or periphery into its interior towards or beyond the centre so as to allow a draught
of air to pass.freely through the cross pipe or tube on all sides and over the top of
the projecting piece in its interior, or, as in the form of a tee piece, one end of &
tube or pipe is inserted through the side or periphery of a larger one, projecting so
far into its interior most suitable to allow the draught of air to pass freely on all
sides and over the top of the projecting end in the interior of the cross pipe
or tube.
It resembles a chimney pot in a tunnel and by being so confined the up draught
is greater, and all down draughts prevented.
They can be made, to be stationary, or, swing round and take the full wind in
whichever way it blows.
The cross pipe or tube and the projection in its interior can be made any shape
or device most suitable.

Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
CHIMNEY POTS OR TERMINALS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
This invention is for the purpose of effectually preventing a down draught or
blow, and creating 50 per cent greater up draught in chimneys, and if used as
ventilators give the very best results.
A tube or pipe b (as shown in Fig. 3. in the accompanying drawings) having a
hollow jutage A, projecting through its side or periphery into its interior towards
.or beyond the centre straight, (as shown by dotted lines in Figure 4, (a con-
tinuation of "A" into tube "b," plain), or as shown by figures 4, and 5, in section,
a continuation of tube A, (narrowed or widened at the end in tube "B," plain), so
as to allow a draught of air to pass freely.through the cross pipe or tube on all
sides and over the top of the projecting piece in its interior resembling a chimney
pot in a tunnel and by being so confined the up draught is greater and all down
draught or down blow is prevented.
Figure 3, in itself shows the up tube A, terminating in a number of conical
rings e, fastened at a distance from each other by four stout wires, d, fixed on the
larger circumference of the conical rings, so that in being swept the brush can be
twisted round and the rings cleared of any soot that is likely to accumulate.
Figure 1, shows a part section with conical rings e (placed further apart
effectually guarding against down blow, and making, an accumulation of soot
sufficient to cause a stoppage impossible) held together by stout wires d, and easily
swept conical rings o are made on cross tube 6 fastened by wires d, to shorten as
much as possible tube B, to allow the rising smoke to clear away quickly and
easily, and to give effect to the double draw on upright tube A, by giving the wind
a slanting direction as it strikes the pot on either side, top, or bottom.
The rings are set about 3 inches apart. Q, is an ornament shown better in
Figures 2, and 3, to take off the appearance of length, Figure 2, is an elevation of
Figure 1, complete.
Figure 6, shows an elevated section made to twist round, (actuated by an arrow
or arrows), always taking the full force of the wind over half conical rings e,
passing out the other side between guards f which are plain or flat pieces arranged
as guards in case it should at any time get fixed and receive the reverse wind, or if
caught before it could get round; it would act as well then as when on the swing
it not being so easy to sweep, on account of the brush not passing the pivot J,
which goes up into the pivot case I, (balancing evenly cross tube B): to prevent
choking, is the reason for placing the guards f a long distance apart.
The lines R show a graduation to a larger circumference at back end of tube B,
so that the wind entering the front shall not jam, through the obstacles 8, but leave
room for expansion if necessary,
H, is the outside case protecting top of tube A. Figure 7 shows a back, and
figure 8, a front view of Figure 6.

page_text: 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
1st A tube A, terminating in the interior of cross tube b, as shown in drawings
by dotted lines in, and sections, Figures 4 and 5.
2nd The tube A, terminating in conical rings in the interior of tubes b, sub-
stancially as here-in before described and set forth in the accompanying drawings
figures 1, and 3.
3rd The conical rings c, substancially as shown in drawings, figures 1, and 2.
