Improvements in or connected with the Manufacture of Ventilators,
Soil Pipe Terminals, and the like.
We, THOMAS CLAUGHTON, JOHN WILLIAM CLAUGHTON, and JAMES HENRY
CLAUGHTON, all of the Firm of Claughton Brothers, of Stanningley, near Leeds,
in the County of York, Plumbers and Lead Founders, do hereby declare the nature
of this invention to be as follows:
The object of our invention is to construct ventilators, soil pipe terminals, and
the like (hereinafter called ventilators) in such a manner that they are much more
durable than those hitherto in use, at the same time such ventilators when con-
structed in accordance with our invention are more readily and quickly produced
than heretofore, thus effecting a great saving in the cost of manufacture.
According to our invention, we form the ventilator of lead or other suitable
metal, and cast the parts forming such ventilator in moulds, and afterwards join
such parts together in the following manner.
The tube or pipe and lower cone are cast in one piece, by the employment of a
chill mould or moulds and draw core, which may be round, square, octagonal, or
any other required shape, the upper edge of the cone being provided with a
projecting turned up flange all round.
A suitable external chill mould or moulds and draw core are also employed to
form the inner deflecting cone, such cone being provided with a projecting straight
flange around its lower edge.
The upper cone and knob are cast in one piece, by the employment of a chill
mould or moulds and draw core, which may be round, square, octagonal, or any
other required shape, such cone being also provided with a projecting turned down
flange around its edge.
The body of the ventilator which joins the upper and lower cones, is cast in
sheet form, by the employment of a top and bottom mould, such body or casting
having perforations of any suitable design cast therein, and provided with a
projecting straight flange along each edge of same. This straight sheet is after-
wards bent into either round, square, octagonal, or any other form required, and the
two edges when brought together are burnt or otherwise joined. The body portion
may, when desired, be cast in one piece to the form required, by employing a chill
mould or moulds in any number of parts, in combination with a draw core; or by
using chill mould or moulds and sand core.
After the parts are formed as above described, we place the flange of the inner
cone, and also the lower flange of the body portion, onto a seat formed in the inside
of the projecting turned up Hange of the lower cone, and then bend or work such
turned up flange over the edges of the said flanges, thereby firmly securing the said
parts in position. The upper cone is now placed in position on the top edge of the
body portion, when the projecting turned down flange of such upper cone is bent or
worked over the upper flange of the body portion, thus firmly securing the parts
together. The flanges which are turned or worked over, for securing the parts
together, may afterwards be burnt or otherwise joined.
It will be seen that by constructing ventilators in parts and afterwards securing
such parts together as above described, such ventilators will be more quickly

durable character.

COMPLETE SPECIFICATION.
Improvements in or connected with the Manufacture of Ventilators,
Soil Pipe Terminals, and the like.
We, THOMAS CLAUGHTON, JOHN WILLIAM CLAUGHTON, and JAMES HENRY
CLAUGHTON, all of the Firm of Claughton Brothers of Stanningley, near Leeds,
in the County of York, Plumbers and Lead Founders, 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 :-
The object of our invention is to construct ventilators, soil pipe terminals, and the
like (hereinafter called ventilators) in such a manner that they are much more
durable than those hitherto in use, at the same time such ventilators when con-
structed in accordance with our invention are more readily and quickly manufactured.
than heretofore, thus effecting a great saving in the cost thereof.
In order that our invention may be clearly understood we will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer to
like parts in all the figures.
Figs. 1, 2, 3 and 4 show the various parts of a ventilator constructed in
accordance with our invention. Fig. 5 a transverse section of a ventilator
in a stage of its manufacture, and Fig. 6 is a similar view to Fig. 5, showing the
same completed.
According to our invention we form the ventilator of lead or other suitable metal,
and cast the parts forming such ventilator in moulds, and afterwards join such parts
together in the following manner :-
The tube or pipe A and lower cone B are cast in one piece as shown at Fig. 1 the
upper edge of the said cone being provided with a projecting turned up flange C and
also with a projecting ridge M on its upper inner edge.
We cast the inner deflecting cone D with a projecting straight flange E around
its lower edge as shown at Fig. 2.
The upper cone F and knob G are cast in one piece as shown at Fig. 3, such
cone F being provided with a projecting turned down flange H around its edge and
also with a projecting ridge N around its inner edge.
The body J of the ventilator as shown at Fig. 4 which joins the upper and lower
cones, is cast in sheet form, such body or casting J having perforations K of any
suitable design cast therein, and provided with a projecting straight flange L along
each edge of same. This straight sheet is afterwards bent round to the required
form, and the two edges J₁ when brought together are burnt or otherwise
joined.
The body portion may, when desired, be cast in one piece to the form required,
by employing a chill mould or moulds in any number of parts, in combination
with a draw core; or by using a chill mould or moulds and a sand core.
After the parts are formed as above described, we place the flange E of the inner
cone D and also the lower flange L of the body portion J onto the seat formed in
the inside of the projecting turned up flange C of the lower cone B as shown
at Fig. 5, and then bend or work such turned up flange C over the edges of the
said flanges E and L as shewn at Fig. 6, thereby firmly securing the said parts in
position. The upper cone F is now placed in position on the top edge of the body
portion J as shown at Fig. 5, when the projecting turned down flange H of such
upper cone F is bent or worked over the upper flange L of the body portion J, thus

page_text: firmly securing the parts together as shown at Fig. 6. The projecting ridges M and N
prevent the body J of the ventilator receding or collapsing during the folding over-
process as the said ridges M and N form secure seats for the metal to rest against..
The flanges which are turned or worked over for securing the parts together, may
afterwards be burnt or otherwise joined.
It will be seen that by constructing ventilators in parts, and afterwards securing
such parts together as above described, such ventilators will be more quickly
manufactured than by the methods hitherto employed, at the same time they will
be of a more durable character.
We would have it clearly understood that the ventilator may be of round, square,.
or other suitable section, and various alterations in construction could be made-
without departing from the distinctive features thereof.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The construction of ventilators, consisting of various parts cast separately, and.
afterwards firmly connected together by means of turned over flanges, substantially
as described.
2. The combination of the tube A, conc B, flange C, ridge M, cone D, flange E,
cone F, knob G, flange H ridge N, body J, perforations K, and flanges L, substan-.
tially as and for the purposes set forth.
3. The general arrangement, construction and combination of the various parts.
forming the ventilator, substantially as herein set forth.
