REVISIONAL DI MUIFICATION
An Improved Chimney Top.
I, THOMAS TUTIN, of 247 Sherwood Street, Nottingham Builder and Contractor
do hereby declare the nature of this invention to be as follows:-
The object of my invention is to prevent down draught, and also increase the
upward draught, so as to cause a chimney to which the device or contrivance
according to my invention may be applied, to draw properly, although said chimney
may have "smoked" previous to the adoption of my said invention.
In carrying my invention into effect I employ a chimney top or terminal, either
made entirely of iron, painted or galvanized but preferably partly of fire clay and
partly of iron. The fire clay portion consists of a pipe from about four to six feet
long, and from nine to twelve inches in diameter, provided with a broad flange upon
the top thereof, for the purpose of holding the windguard, attached thereto by means
of nuts, bolts and straps, which may be renewed at pleasure.
Said windguard consists of four or more, (preferably nine) circular louvres, fitted
together by rivetting, or equivalent method, one over another, one or more inches
apart, the whole being bolted to the flange upon the fire clay pipe so as to he
removeable when necessary.

COMPLETE SPECIFICATION.
An Improved Chimney Top.
I THOMAS TUTIN of 247 Sherwood Street in the County of Nottingham, Builder
and Contractor 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 a method of, and appliances for, the prevention of down
draught, and the increase of the upward draught, so that the chimney to which the
device, or contrivance according to my invention, may be applied, may draw
properly, notwithstanding that said chimney may have smoked previous to the
adoption of my said invention.
In order that my Invention may be the better understood I have appended the
accompanying sheet of drawings. Fig. 1 is an elevation of a chimney, or terminal
fitted with nine louvres according to my Invention. Fig. 2 is a view shewing one of
the said louvres inverted for the better illustration of the under surface thereof, the
lugs, or projecting pieces thereon a al all will be hereinafter more fully explained.
Fig. 3 shews the reverse, or upper side of said louvre.
In carrying my Invention into effect 1 employ a chimney top, or terminal, either
made entirely of iron, or other suitable metal, painted or galvanized, but preferably
partly of fireclay and partly of iron. The fireclay portion consists of a pipe from
4 to 6 feet in length and from 9 to 12 inches in diameter, provided with a flange,
upon the top thereof for the purpose of holding the wind guard attached thereto by
means of a strap, nuts and bolts. Said windguard consists of 4 or more (preferably
nine) louvres placed one over the other as shewn in Fig. 1, and kept one or more
inches apart by means of the lugs, or projecting pieces a al all Fig. 2, and the
whole is held firmly in position by means of 3 or more bolts, or rods placed in a
vertical position within the said louvres, and bolted, or otherwise firmly attached to
the strap B Fig. 1, stretched round the outer surface of the chimney pot close up to

page_text: the flange, or rim A and fixed by means of the bolt and nut C. or I may as an
alternative arrangement employ strips of iron, or zinc instead of the bolts, or rods
before mentioned, and bend each at the top end to grasp the top, or uppermost
louvre, and pass the lower ends of said strips within and under the before mentioned
strap B and turn them up outside the same as shewn at D D and E E' Fig. 1, the
bolt and nut C holding the whole together as before described.
I have found in practice that whereas the draught of a certain type or position of
chimney may be improved by the use of 3 or 4 of the louvres according to my
Invention another type, or position of chimney may require 10 or 12 before the
draught is perfect, and the novelty of my Invention is apparent from the fact that
any number of said louvres may be superimposed upon each other until the desired
updraught and the downdraught prevented when the whole may be rigidly fixed in
the manner herein set forth and shewn.
The said louvres according to my invention may be of iron or other suitable metal
painted, or galvanized, and the lugs, or projections a a' al rivetted, or cast thereon,
or said louvres may be made of fireclay or glazed earthenware and the lugs or
projections cast therewith, and may as an alternative arrangement make said louvres
of square, or other form in order that they may be adapted to chimneys of such
shapes in cross section.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The improved windguard and chimney top for the prevention of down-draught in
chimneys, substantially as herein described and shewn in the accompanying sheet of
drawings.
