Year: 1878

page_text: LETTERS PATENT to William Brown, of the City of York, in the County of
York, for the Invention of "IMPROVEMENTS IN AND CONNECTED WITH DRAINS
FOR HOUSES AND BUILDINGS."
Sealed the 1st October 1878, and dated the 13th April 1878.
PROVISIONAL SPECIFICATION left by the said William Brown at the Office
of the Commissioners of Patents on the 13th April 1878.

IMPROVEMENTS
My improvements refer to the production of a ready means, whereby the interior
of syphon drains may be accessible for cleansing purposes, and also to a trapped
cover for the opening in the said syphon or syphon pipes. These improvements are
applicable where single or double syphon pipes are employed, and are as hereafter
described.
In the syphon pipes constructed in accordance with my Invention, I dispense
with the top portion of the upper elbow which leaves an opening into the interior
of the syphon. I provide an outer and an inner flange round this opening, and at
such a level with regard to the lower bend or elbow of the syphon, that when it is
filled with water, a portion thereof overflows the inner flange and fills up the space
between that and the outer flange.
I construct a cover, cap, or lid, which is made of incial, earthenware, or of any
other suitable material; this is hollowed out to form the top portion of the upper
elbow, carrying out thereby the interior shape of an ordinary syphon. The edge of
the cover, cap, or lid, when put on to the syphon, is dropped between the herein-
before mentioned inner and outer flanges of the same, the space between which
having been previously filled with water in combination with the cover, cap, or lid,

pressure.
I provide on the upper portion of the cover, cap, or lid, suitable handles or pro-
jections, whereby it may be removed for cleansing purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Brown in the Great Soal Patent Office on the 11th October
1878.

"IMPROVEMENTS
My improvements refer to the production of a ready means, whereby the interior
of syphon drains may be accessible for cleansing purposes, and also to a trapped
cover for the opening in the said syphon or syphon pipes. These improvements are
applicable when single or double syphon pipes are employed, and are as hereafter
described.
In the syphon pipes constructed in accordance with my Invention, I dispense
with the top portion of the upper elbow which leaves an opening into the interior
of the syphon. I provide an outer and an inner flange round this opening, and at
such a level with regard to the lower bend or elbow of the syphon, that when it is
filled with water, a portion thereof overflows the inner flange, and fills up the space
between that and the outer flange.
I construct a cover, cap, or lid, which is made of metal, carthenware, or of any
other suitable material; this is hollowed out to form the top portion of the upper
elbow, carrying out thereby the interior shape of an ordinary syphon. The edge of
the cover, cap, or lid, when put on to the syphon, is dropped between the herein-
before mentioned inner and outer flanges of the same, the space between which
having been previously filled with water in combination with the cover, cap, or lid,
forms a trapped joint through which the obnoxious gases cannot pass unless under
pressure.
I provide on the upper portion of the cover, cap, or lid, suitable handles or pro-
jections, whereby it may be removed for cleansing purposes.
And in order that my Invention may be more completely understood, reference is
given to the accompanying Drawings, and to the letters and marks thereon.
Figure 1 is a longitudinal section, and Figure 2 a transverse section.
« is the opening which I provide at the upper elbow of the syphon b, round which
opening are arranged the outer flange c, and the inner flange a constructed in such
a manner with regard to the lower bend e of the syphon, that when it is filled, the
water overflows the inner flange d, and fills up the space f between that and the
outer flange c.
I construct a cover, cap, or lid g of metal, earthenware, or other suitable materials.,
this is hollowed out as shewn at h, to form the top portion of the upper elbow
carrying out thereby the interior form or shape of an ordinary syphon. The edge i

page_text: of the cover, cap, or lid g when put on to the syphon, is dropped between the
Banges c and d, the space between such flanges when preferred having been pre-
viously filled with water. Instead of the space f being filled with water, clay or
other equivalent means may be employed for forming the joint through which
obnoxious gases cannot pass unless under pressure.
On the upper portion of the cover, cap, or lid, suitable handles or projections J
are formed, whereby it may be removed for cleansing or other purposes.
Having thus described my Invention, and means which I adopt in carrying the
same into effect, I would have it understood that I do not confine myself to the
precise form or shape of the cover, cap, or lid, or to other of the details as shewn
and described, as the same may be varied without departing from the peculiar
character of the Invention, but what I claim is,-
The arrangement, construction, and application of cover, cap, or lid g in combi-
nation with a syphon on having an opening a at its upper bend and parts con-
nected therewith for preventing obnoxious gases escaping, substantially as and for
purposes herein set forth.
In witness whereof, I, the said William Brown, have hereunto set my hand
and seal, this Eighth day of October, in the year of our Lord One thousand
eight hundred and seventy-eight.
