that is to say:-
My Invention consists in constructing chimney tops or cowls in the manner
hereafter explained, and illustrated in elevation in Figure 1, and in section in
Figure 2 of the said Drawings. I form my chimney tops or cowls of two
principal parts A and B, the former A being fixed upon the chimney, and the
latter B being free to revolve over the fixed part. The fixed part A ter-
minates at top in rows of deflecting plates a, a. The movable part B is in the
form of a lobster back 6, placed inside a cylindrical or other shaped case c.
The lower part of the lobster back is furnished with deflecting plates d, d,
opening into the outer case, for the purpose of stopping the down-draught and

rod or spindle e, round which it is free to turn according to the direction of the
wind, the spindle e entering into the long socket f, upon the top of which is
the vane g.

In witness whereof, I, the said John Martyn Fisher, have hereunto set
