Improvements in puraugu
JAMES LINKLETER, Tyneside Works, Tynemouth, Patentee and Manufacturer, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of producing an updraught for
chimney tops, ventilators, gas stoves, for house and ship ventilation and the
like.
It is so designed that it can be made either in metals or pottery, further that
it can be cleaned and freed from soot or dust by chimney sweeps in the ordinary
way, without damage or inconvenience.
To this end. I make a cylinder to the required diameter, to the top of which,
I fix a rim bevilled downward, the outer edge being about twice the diameter
of the cylinder. I then make a bowl shaped cover of the same diameter as the
bevilled rim, this cover which resembles an umbrella in shape is held in position
above the bevilled rim by three stays close to the cylinder. Through the bevilled
rim three holes are made at equal distances apart which receive the stays, the three
stays then slide down against the outside of the cylinder, so that when sweeping
or cleaning the inside of cylinder from below, the cover is lifted up by the sweeper
and slides up and down guided by the three stays.
'
Small guide loops are provided lower down the cylinder, which support the
bottom ends of stays and prevent the cover from being knocked off.
The action of wind blowing in any direction, especially downward about the
cover. produces an updraught in the cylinder, thus having the same effect as
a spray producer.

Improvements in Updraught Producers.
JAMES LINKLETER, Tyneside Works, Tynemouth, Patentee and Manufacturer, 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 improved method for producing an updraught for
chimney tops, ventilators, gas stoves, for house and ship ventilation and the

page_text: It is so designed that it can be made either in metals, pottery or other material,
further that it can be cleaned and freed from soot or dust by chimney sweeps in
the ordinary way, or regulated, without damage or inconvenience.
To this end I make a cylinder to the required diameter, to the top of which
I fix a rim bevilled downward (preferably of convex form) the outer edge being
about twice the diameter of the cylinder. I then make a bowl shaped cover of
the same diameter as the bevilled rim, this cover which resembles an umbrella
in shape is held in position above the bevilled rim by one or more stays close to
the cylinder. Through the bevilled rim holes are made at equal distances apart
which receive the stays, the stays then slide against the outside of the cylinder,
so that when sweeping or cleaning the inside of the cylinder from below the
cover is lifted up by the sweeper, and slides up and down guided by the stays.
Small guide loops are provided lower down the cylinder which support the
bottom ends of stays and prevent the cover from being knocked off.
The action of the wind blowing in any direction especially downward about the
cover produces an updraught in the cylinder, thus having the same effect as
a spray producer.
In some cases a centre stay may be used resembling an umbrella shank, for
manipulating and regulating the draught from below, such as in railway carriages
and the like.
DESCRIPTION OF DRAWINGS.
In the Drawings A. is the cylinder, B. the bevilled rim, C. the cover and D.
the stays.
Fig. 1. Shews how the cover C. and the bevilled rim B. changes the wind from
any direction to the right angle for producing an updraught in the cylinder A.
Fig. 2. Shows how the downdraught acting on the cover C. then on the bevilled
rim B. draws the air or smoke from under the cover C. and so producing an up-
draught in the cylinder A.
Fig. 3. Shews the advantage of the moveable cover C. for cleaning purposes S.
representing sweeps brush.
Fig. 4. Shews the advantage of the moveable cover C. for ship ventilation in
wet and stormy weather.
Fig. 5. Shews the cover C. closed down thus making it watertight when the sea
is breaking over the ship.
Fig. 6. Shews how large updraught producers can be ornamented for large
buildings, sewer ventilation and the like.
Fig. 7. Shews how it can be fitted on to shop fronts with cylinder horizontal, for
ventilating purposes.
Fig. 8. Shews plan.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1st. Making an updraught producer having the combination of cylinder with
bevilled rim, and cover..
2nd. Making an updraught producer having a moveable cover for cleaning
and regulating purposes.
