page_text: We JAMES NUTTALL of No. 15. Dane Street Rochdale in the County of
Lancaster Tin plate worker, FRANCIS NUTTALL of No. 40, Pembroke Street
Oldham Blacksmith in the aforesaid County and JOHN ROUSE of No. 10 Mitchell
Street Oldham aforesaid Doubler. do hereby declare the nature of our invention
for "A METHOD OF AND APPARATUS FOR PURIFYING NOXIOUS OR GASEOUS
VAPOURS ARISING FROM HEATED LIQUIDS OR OTHER MATERIALS WHICH INVENTION
IS CHIEFLY APPLICABLE TO COOKING STOVES" and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:―
Our invention is applicable to stoves or fire places for purifying foul or noxious
vapours, or to apparatus, generally used for cooking by the use of oil or other
liquids potatoes fish and other like matters it is well known that as at present
used for these purposes the fumes or vapours arising from the commodities under
process of cooking are not confined but allowed to escape into the room or place
wherein the operation of cooking is being performed thus an offensive and injurious
odour pervades. the room or place, our arrangement has for its object to obviate
the escape of any offensive or injurious gases or vapour into the atmosphere
therefore to eradicate the nuisance caused thereby. so that our invention may be
better understood we refer to the accompanying sheets of drawings shewing our
apparatus applied to an ordinary cooking stove the same letters throughout the
drawings in the various figures represent like parts.
Figure 1. represents a side elevation of a stove with our apparatus attached,
Fig. 2 represents a side elevation in section at A A of Fig. 1. Fig. 3 a front
sectional elevation of Fig. 1. at B. B. Fig. 4 is a sectional elevation of Fig. 1
at C. C.
Our arrangement consists of a metal cover or bomnet D fitted on the plate E
of the Stove F, the fumes or vapours arising from the liquids used in cooking or
manipulating potatoes fish or other matters naturally ascend in the chamber G the
front extremity of the chamber being open so as to allow the air to freely enter,
at the back of the chamber is an opening H leading to a draught pipe, tube, or
conduit I which is contracted or enlarged at its extremities as required to
accomodate the current of air shewn in Fig. 2. and terminates in the door of the
stove leading to the heat chamber J as shewn in Figs. 2, and 3. thus the fumes or

page_text: vapours arising from the well K are caused to traverse through the chamber J by
the action of the air in the pipe or outlet L of the stove.
It is obvious that there will be a continual current of air at the opening H so
long as the heat chamber J and the tube or conduit I for the passage of noxious
vapours are kept perfect y enclosed thus causing with the aid of the air entering
the front extremity of the chamber G all disagreeab'e or gaseous vapours rising
from the well K to impinge on the upper surface of the midfeather or plate M and
consequently follow the direction of the current as shewn by the arrows, it will
be manifest that the fumes in their passage through the heated chamber J will
be divested of any impurities before emission through the outlet L into the
atmosphere.
The upper part of the cover or bonnet D is provided with a plate forming a
recess or chamber N which affords accomodation for food after being cooked and
obviously acts as an auxiliary heat chamber at its back extremity it is provided
with a tube or pipe O. fitted into the plate R. extending into the draught pipe or
conduit the office of which is to carry off the steam or vapour which may
accumulate in the said chamber during the storage of any prepared food therein.
We wish it to be understood that we do not confine our-elves to the exact
details as shewn in the annexed drawings as the same our invention may be
applied in many different ways without departing from the principle of this said
invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1
1. A method for purifying noxious or gaseous vapours arising from heated
liquids oily or other matters by conveying the same through heat by means of the
conduit or pipe or tube for the purposes herein set forth and substantially as
described.
2. Apparatus used for the method of purifying noxious or gaseous vapours
arising from heated liquids oily or other matters consisting of the cover or
bonnet D the plate R. the pipe O. the conduit or pipe I berein and for the purposes
Bet forth.
