PROVISIONAL SPECIFICATION.
An Improved Combined Chimney Pot and Cowl for the Prevention
of Downdraught in Chimneys.
We JAMES EDWARD HARGREAVES, of Lerwick, Shetland Isles, Wesleyan
Minister, and THEOPHILUS LESSEY HARGREAVES of Kent Street, Hull in the
County of York, Blacklead Manufacturer do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to construct a combined chimney pot and cowl to
be placed on the chimney stacks of buildings for the purpose of preventing any
down-draught in such chimneys, and allowing at the same time the smoke to pass
freely away and not to be blown back into the rooms of such buildings, thus being
an effectual preventative of smoky chimneys; it also prevents snow, rain, and
wind from entering therein.
We construct our invention as follows:-
We employ a bent tubular pot or cowl which may be made of galvanised sheet
iron hent to the required shape, or of any suitable material such as fireclay or the
like, this pot or cowl has a flange at the bottom for the purpose of allowing it to be
built into the chimney stack.
From the flange the pot rises in the form of a vertical tube a suitable distance,
then it is bent over or inclined for a short distance, it then rises vertically again.
At the parts where the bends are made, an opening is formed on the underside
of the tube and suitable projections or traps are formed inside for the purpose of
preventing any down-draught carrying the smoke back into the chimney, such
smoke passing away through the openings formed underneath at the said bends.
With the aforesaid construction of chimney pot and cowl, it is almost impossible
for any smoke to be blown back into the chimney, as the traps formed in the bends
inside the cowl, stop its passage and cause it to pass away through the openings
formed at such bends underneath, for the purpose of carrying off such smoke if
blown back.

We JAMES EDWARD HARGREAVES of Lerwick, Shetland Isles, and
THEOPHILUS LESSEY HARGREAVES of Kent Street, Hull in the County of

invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of our invention is to construct a combined chimney pot and cowl to

DESCRIPTION OF DRAWINGS.
Fig. 1. shews elevation of our improved combined chimney pot and cowl.
Fig. 2. is a section of Fig. 1.
We construct our invention as follows:-
We employ a bent tubular pot or cowl A which may be made of galvanised
sheet iron bent to the required shape, or of any suitable material such as fireclay
or the like, this pot or cowl has a flange B at the bottom for the purpose of allowing
it to be built into the chimney stack C.
From the flange B, the pot rises in the form of a vertical tube D a suitable
distance, then it is bent over or inclined for a short distance, at E, it then rises
vertically again at F.
At the parts where the bends are made, openings G are formed on the underside
of the tube, and suitable projections or traps H are formed inside to act as checks
to prevent any downdraught carrying the smoke back into the chimney, should
Buch occurrence take place, it will come in contact with the checks or traps H, and
must pass away through the openings G formed underneath at the said bends.
With the aforesaid construction of chimney pot and cowl, it is almost impossible
for any smoke to be blown back into the chimney, and by that means into the
apartment, it also prevents snow, rain, wind and the like from entering therein.
Having now particularly described the nature of this invention and in what
manner the same is to be performed, we declare that what we claim is :-
A combined chimney pot and cowl consisting of a tube bent or formed as at D, E,
and F and having traps or checks H, and openings G, as and for the purposes
substantially as shown and described.
