COMPLETE SPECIFICATION.
Improvements in Chimney Tops, Pots, and Cowls.
I, MILES SMITH, of 225 Queens Road, Halifax, in the County of York, "Joiner"
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 improvement in chimney tops, pots and cowls, such
improvements consisting of vertical slots in each side of shaft of chimney top or cap,
whereby a clear blow through is maintained, and down draught prevented; applicable
in cases where discharges of smoke, impure air and stench take place.
My Invention may
other inaterial.
be constructed of earthenware, zinc, galvanized iron, or of any
And in order that my Invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof, reference being had to letters and figures
marked thereon.
Figure 1, represents an elevation of the chimney pot, with the aperture C in the
lower portion of the chimney pot, the said aperture C is placed on the opposite
side A, for the purpose of permitting a direct passage for the wind to blow through,
or for the smoke to come out.
Figure 2, is an elevation of figure 1 describing the side face B, with the aperture C
in the upper portion of the chimney pot, the said aperture C is also placed on the
opposite side B, to permit a direct passage for the wind to blow through, or for the
smoke to come out.
Figure 3, denotes a plan of the upper portion of the chimney pot, on line b, of
figure 2. A clear blow through is indicated by arrows, these apertures C, C, being on
the faces of the chimney pot B, B.
The object of my Invention is that when the draught enters the top or mouth of the
chimney pot, it will expend itself out of the apertures C, before it has sufficient
force to pass down the flue, and to drive the smoke through these said apertures at
the same time.
Having now fully. described the nature and object of my Invention, and the
manner in which the same is to be performed, I claim as new:-
:
First The chimney top or pot, with vertical apertures C, on the sides of A, A,
and B, B, to permit a clear blow through, and to prevent down draught, substantially
as herein described and according to the accompanying drawings.

page_text: Secondly: The chimney top to be constructed of earthenware, zinc, copper,'
galvanized iron, or of any other material, and the vertical apertures to be placed in any
desirable position, substantially as herein described.
