Improvements in and in connection with Chimneys, Chimney Tops,
and the like.
I, EDWIN HUTCHINS, back of No. 26 Clump. Buildings Humberstone Road
Leicester in the county of Leicester Builders Merchants foreman, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in and in connection with chimneys, chimney
tops, and the like, and to provide contrivances that will effectually obviate down
drafts, and carry off the smoke in the direction the wind is blowing, and automatically
keep the chimney pot, or if the chain be made long enough, the chimney may be
kept clean, or from getting blocked up with soot, the working parts are kept lubricated
and being enclosed in the roof, or cap, or cowl are kept clean.
I make a pot and cowl in the following manner and also modified constructions
thereof.
The chimney pot may be circular and bell shaped at base, the top or upper surface
grooved to admit the bottom end, or supports of the cover, cap or cowl to keep it firm
in the upright position, and also secured by pins or screws in holes prepared therein
preferably at the top of the pot on the outer sides I have beadings to strengthen it,
and to secure it against sudden gusts of wind, the cover, cap or cowl is constructed
before being attached to the pot and having supports from the roof downwards for
attaching it to the pot, into the head or top of these supports I fit a brass boss which
carries a vertical spindle, with a small outer tube fitted thereon under the oil chamber,
the lower end of the spindle passing through an iron ceiling and carrying inside of
this a swinging bar to each arm are secured chains banging loose in the inside of the
pot, of any pattern that the links will hang perfectly free that by the movement of the
fane or vane fitting at the top of the spindle the chains swing parallel to the. inner
sides of the chimney, the chains only requiring to be small in width to obviate the
clanging of the links, an oil chamber, or lubricating cup is provided to keep the
spindle oiled, and in working order and is covered by a taper washer and nut under
the fame or vane, below the swinging bar at the base of the spindle is an outlet trap or
door for the smoke which opens by the movement of the fane or vane and allows the
smoke to escape only in the direction of the wind.
The fane or vane is by preference corrugated and at right angles to the corrugations
is a narrow rim down the edge of the vane making the same more susceptible to the
wind. Or I may employ upon an ordinary chimney pot a top or cover of any suitable
material with supports secured to and around the upper part of the pot. A swinging
bar carrying the cleaning chains screwed or otherwise fastened at the lower end of the
spindle working in an outer tube, the top of the spindle secured by a nut on a washer
over the lubricating cup at the upper end of the spindle, the arms of the fane or vane
coming down about level with the top of the cover and the bottom of the arms
adjusted to a circular plate, or a plate formed to fit the sides of the cover, and about
half of the diameter of the cover, thus when the wind moves the vane the smoke will
only issue in the same direction as the wind.
The contrivances herein described may be made of metal, galvanized iron, pot, or
any material ordinarily used for the purpose-Or I may put the vane simply with a
cross bar and cover and automatic cleaning appliance to ordinary chimney pots
and stacks if desirable.

Improvements in and in connection with Chimneys, Chimney Tops,
and the like.
I, EDWIN HUTCHINS late of back of No. 26 Clump Buildings Humberstone Road
but now of No. 38 Rutland Street,. Leicester, in the county of Leicester, Builiers
Merchants Foreman, 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:-
This invention relates to improvements in and in connection with chimneys, chimney
tops, and the like to provide contrivances that will effectually obviate down drafts and
carry off the smoke. in the direction the wind is blowing, and at the same time
automatically keep the chimney pot; or if the chain be made long enough the chimney
quite clean; or from getting blocked up with soot, the working parts are kept in
order by the lubricant being enclosed in a cup in the roof, cap or cowl, and a cure for
smoky chimneys is effected by the arrangements or contrivances herein specified and
illustrated in the drawings annexed in which Figure 1 is a sectional view of a chimney
pot A, and cover hereinafter described. Figure 2. is another form of cover upon an
ordinary chimney pot.
Figures 3 and 4 are views of the small swinging bars, or stars J¹, as used in
Figure 2.
Figure 5. is a top view of the inner cover, or ceiling C¹.
Figure 6. is a cut off view of the cover C, having the vertical supports and strips (4,
the upper angle ends 13, carry the swinging bars, or stars J', the bands C5 cover the
said bars and chains and they are hidden from view.
Figure 7. is a cut off view in section of the cover C, are ranged round the interior
of the cover, the lower ends thereof come just above and preferably flush with the
mouth of the chimney, or chimney pot.
I make the pot and cowl in the following manner, also modified constructions
thereof in iron, Tin, or cast the several parts in clay, earthenware and the like.

al
The chimney pot A, may be circular or of any fancy shape or design, bell shaped
at base preferred, the top edge, or upper surface being grooved, B to admit the bottom
ends of the vertical strips, or supports of the cover, cap and cowl C, are made secure
by pins or screws C2 "as will be seen by the drawings," the rim or beading 1), near the
top on the outer side is to strengthen the pot and secure it against sudden gusts of
wind, the cap, bonnet or cowl C, is secured to the angle end of the supports C,
figure 2" and extend downwards; in the head or top I fix a brass boss E, in which is
carried the vertical spindle F, having a small outer tube G, fitted thereon under the
oil chamber."shown in dotted line," the lower end of the spindle passing through
hole in the iron ceiling or earthenware cover H, upon the lower end of the spindle
is placed the swinging bar or star I, to which are secured the chains J, their free
ends hanging loose in the inside of the pot A, the links of which may be of any pattern
that will hang perfectly free, when the fane or vane K, is moved by the wind the
chains will swing parallel to the sides of the chimney pot, or sides of the upper part
of the chimney, the chains are small in width to obviate the clanging of the links; an
oil chamber, or lubricating cup L, is provided to keep the spindle lubricated
antomatically and in working order, and is covered by the taper washer M, and
nut N, under the fane or vane K, below the swinging bar or star I, level or there-
abouts with the base of the spindle is an opening, trap or door O, in the cover (), for
the smoke outlet which is in a corresponding position to the vane K, and allows the
smoke to get away only in the direction of the wind by the rotation of the cowl C.
The fane or vane K, is by preference corrugated as shown in figure 1, and at
right angles to the corrugations is a narrow rim down the edge of the vane that
it may be more susceptible to the wind. Or I may employ upon an ordinary chimney
pot of the kind shown in figure 2, a top'or cover C, of any suitable material, the
strips or supports secured by pins in grooves, or to a band put round the top of the

page_text: pot A, the swinging bar or star H, on the short spindle G, secured by the nut 1, and
the small swinging bars or stars J, carrying the cleaning chains J, their free ends
passing through the circular holes, or chimneys C³, in the inner cap or cover C; the
lubricating cup E, in this case is made smaller and the outer tube or pipe F, on the
vane spindle G is shorter.
The stars are carried on pins in the angle supports J³, and are operated on, so that
the cleaning chains will act; by the lower end of the chains J, which are suspended
from the ends of the swinging bar H, catching against the points thereof.
It will be seen that the outer supports C, are secured to the inner cover C¹, by pins
or screws C, and an outlet space C³, is left at the bottom of the inner cover so that
any down draft makes its escape without getting into. the chimney pot, or chimney.
The vane being employed in this case for operating the cleaning chains to obviate
the soot collecting in the chimney pot or cover. The point of the arrows denote the
outlet passages, and also the up draft for the smoke.
The contrivances herein shown and described may be made of any suitable material,
and I may put the fane or vane K, and cover C, with the swinging bar H, and
cleaning chains connected thereto to chimney stacks without employing a pot if
necessary. I do not confine myself to the pattern or shape of the cover as herein
illustrated for chimney pots are square, others octagonal, circular, and all sorts of fancy
forms. It will be observed that the contrivances herein described resemble somewhat
the form of a ventilator it acts successfully as a preventor and ventilator combined.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A cover, cap and cowl for chimney pots, or chimneys having the internal
arrangements or contrivances constructed in the manner described.
2. In connection with chimneys, chimney tops and the like the employment of
swinging bars or stars, with cleaning chains attached thereto; the inner cover with
the holes, or chimneys arranged therein, or chimneys internally secured to the cover
for the prevention of down drafts in the manner shown and described.
3. Improvements in and in connection with chimneys, chimney tops and the like,
all substantially in the manner and for the purpose hereinbefore described and set
forth.
