DIEVIFICATION.
We THOMAS SILK WILSON and HENRY THOMAS JOHNSON both of the City of
Manchester in the County of Lancaster, Surveyors do hereby declare the nature of
the said Invention for AN IMPROVED APPARATUS FOR USE IN THE VENTILATION
OF SOIL PIPES AND OTHER PARTS to be as follows:-
:-
Our Invention relates to a former Invention for which Letters Patent bearing
date the Eleventh day of August in the year 1882 and numbered 3829 have been
granted to us. In the carrying into effect of our said former Invention we
employed gas burners enclosed within casings which were connected with soil pipes,
drains, middens and other places and in Fig. 8 of the Drawings which accompanied
the Specification descriptive of our said former Invention we illustrated an
apparatus for connection with a soil pipo or drain and it is to this apparatus that
our present Invention more particularly relates.
In lieu of the Bunsen burner and fire clay mass in our former apparatus we uso
an Argand burner having a chimney of copper, porcelain, fire clay or other suitable
material which is enclosed within one or more shells which are themselves enclosed
within the outer casing and become heated by the heat radiated from the said
chimney. The up current flows through the space between the chimney and the
surrounding shell meeting and mingling with the highly heated air and gases
issuing from the chimney and by preference the current then descends through
the space between the said shell and a second surrounding shell before passing
upward to the exit. To check down draughts we provide the shells with a
conical cover and outlet openings in the outer casing and in some or in all cases
we make the said cover double with a central chimney or outlet. In cases wherein
the down draughts would be likely to interfere with the flame we supply air to
support combustion through a pipo or pipes passing to the outside of the casing.
We, do not confine ourselves to the use of an Argand burner.
The apparatus so constructed is applicable for use in the ventilation of rooms or
of parts of hospitals and other buildings in addition to the uses indicated in our
said former Specification.

Manchester in the County of Lancaster, Surveyors, do hereby declare the nature of
the said Invention for "AN IMPROVED APPARATUS FOR USE IN THE VENTILATION
OF SOIL PIPES AND OTHER PARTS" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement (and accompanying Drawings) that is to say :--
Our Invention relates to a former Invention for which Letters Patent bearing
date the Eleventh day of August in the year 1882 and numbered 3829 have been
granted to us. In the carrying into effect of our said former Invention we
employed gas burners enclosed within casings which were connected with soil
pipes, drains, middens and other places and in Fig. 8 of the Drawings which
accomped the Specification descriptive of our said former Invention we illustrated
an apparatus for connection with a soil pipe or drain and it is to this apparatus
that our present Invention more particularly relates. In lieu of the Bunsen burner
and fire-clay mass in our former apparatus we use an Argand burner having a
chimney of copper, porcelain, fire-clay or other suitable material which is enclosed
within one or more shells which are themselves enclosed within the outer casing
and become heated by the heat radiated from the said chimney. The up current
flows through the space between the chimney and the surrounding shell meeting
and mingling with the highly heated air and gases issuing from the chimney and
by preference the current then descends through the space between the said shell
and a second surrounding shell before passing upward to the exit. In cases
wherein the downdraughts would be likely to interfere with the flame we supply
air to support combustion through a pipe or pipes passing to the outside of the
casing.
The apparatus so constructed is applicable for use in the ventilation of rooms
or of parts of hospitals and other buildings in addition to the uses indicated in
our said former Invention.
In order that our Invention may be fully understood we have attached hereto a
sheet of Drawings made to a scale of about three inches to the foot. Referring to
the said Drawings Fig. 1 illustrates the application of our apparatus in the
ventilation of rooms, or buildings or parts of buildings. Fig. 2 represents a
vertical section of the said apparatus. Fig. 3 represents a vertical section and
Fig. 4 a horizontal section of the apparatus adapted more particularly for
application to soil pipes and for similar uses.
In Fig. 2a is an Argand burner which is enclosed within a number of cylindrical
metal shells which are fixed in a casing b. The inner shell c serves as a chimney
for the burner and takes the place of the glass chimney in the ordinary use of the
burner. This chimney is surrounded by a second shell & which is enclosed within
a third shell e. The shell becomes heated by radiation from the chimney
whereby an upward air current through openings at f, f, is induced. Air to support
the combustion of the gas is admitted at g. The products of combustion and
heated air passing up the chimney are deflected by a disc cl into the upper part of
the annular space between the chimney c and the shell & and flowing upward are
deflected downward by the crown c¹ of the shell e. A small opening is formed in
the crown e¹ in order to provide for a direct passage through the apparatus until
the heating of the parts causes the proper currents to be established. From the
lower part of the space between the shells d and e the heated current flows into

page_text: the annular space between the shell c and the outer casing b and passing upward is
discharged through a delivery pipe h. Air is admitted through openings i, i,
through which upward currents are induced by the upward flowing heated
products so that à considerable current is discharged through the pipo h. The
arrows indicate the flow of the currents through the apparatus. In Fig. 1 the
apparatus is represented as being seated in a recess formed in the wall of a room
close to or near to the ceiling. In front of the said recess is a casing & which is
provided with a door k'. Air from the room is admitted through an opening 7 and
passing downward below a mid-feather menters the space surrounding the casing b.
The pipe & discharges into a larger pipe n which is continued to any suitable point
of discharge a suitable cap or cowl being provided to prevent down draughts. Tho
apparatus becoming heated induces an upward flow of air into the larger pipe n so
that with the additional current passing through the apparatus a considerable
discharge of air is obtained. The gas burner is supplied by means of a pipe which
is provided with a suitable rogulator o so that a constant calculated consumption of
gas can be provided for. The apparatus illustrated by Figs. 3 and 4 is adapted for
outside situations the example being made suitable for fixture to the wall of a
building. The casing is provided with a branch p whereby the apparatus can bo
connected with a soil pipe or with an upcast pipe extending from a sewer, ash-pit
or other similar place. The burner is supplied with air from the exterior of the
outer casing through pipes or passager which are provided with shields 8. The
lengthened exposure of the sower gases to the heat generated in the apparatus is
intended to destroy disease germs or organic matter as in our former Invention.
The casing is provided with a coned cover t which is wider than the top of the
casing so that openings are left at t¹, t¹ the intention being to provide for the
discharge of a down rush of air. To still further check downdraughts a baffle
plate u is fixed below the covert and is perforated for a distance from its edge the
central part which is immediately below the discharge pipe being free from
perforations. In the example the said discharge pipe is provided with a perforated
cap or hood but in some cases the pipe h would be extended upward so as to
deliver the air and gases at any desired point or elevation. Openings closed by
means of doors v, v, are formed in order that access can be had to the burner to
light the gas. We do not confine ourselves to the use of an Argand burner nor to
the cylindrical formation of the shells nor to the number of the said shells.
P
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. The combination of parts forming the apparatus formed and arranged
substantially as and for the purposes set forth and indicated hereinbefore
and in and by the accompanying Drawings.
2. The apparatus provided with a gas burner and with shells for heating air
currents and for directing the flow of such currents for use in the abstraction
of air or of gases from rooms, buildings, soil pipes and other places or parts
substantially as set forth and indicated.
