PROVISIONAL SPECIFICATION left by the said Edward Green at the Office

⚫ EDWARD GREEN of the Firm of Oates and Green of Halifax in the County of
York, Fire Brick and Sanitary Tube Manufacturers "AN IMPROVED SEWAGE TRAP
OR GULLEY AND IN SOCKET PIPES THEREFOR "}
: This Invention has reference to that class of Trap or gulley called house and yard
traps and generally employed in connection with cottages or other houses to trap
from the sewers.
The form of the exterior of the trap may be square, round, or other convenient
shapes, in the interior I form two traps one at the top where the inlet is situated,
and another at the bottom where the outlet is situated. Above the outlet I place
an iron frame and grate with hinges so as to get at the inside of the trap for the
purpose of cleaning out; or (if preferred) in place of a frame and hinged grate
I use a pot or iron shoe grate, made to fit an opening in the trap which can be put
in and taken out when the trap requires cleaning.
On the outlet pipe I make an opening covered by a lid for the purpose of intro-
ducing a cleaning rod to clean out the pipes connected therewith. This kind of
trap is especially applicable for all houses or buildings where there is no front line
or where they are built back to back and where the trap is required to be under
the wall. I use a dish stone made with a lip or spigot underneath to fit into the
socket of the trap. The outlet of the trap may be connected with the sewer by
means of an ordinary socket pipe or a socket pipe having its end bevilled or rounded
which fits into a correspondingly bevilled or rounded socket to facilitate the moving
of the pipes to the varied angles of the sewer and yet ensuring a perfect tight
joint.

by the said Edward Green in the Great Seal Patent Office on the 23rd April
1883.
EDWARD GREEN, of the firm of Oates and Green, of Halifax in the County of
York, Fire-Brick, and Sanitary Tube Manufacturers "AN IMPROVED SEWAGE TRAP
OR GULLY AND IN SOCKET PIPES THEREFOR,"
This Invention has reference to that class of Trap or gully, called house and
yard traps or wall trap and generally employed in connection with cottages or
other houses, to trap from the sewers.
In order that my Invention may be better understood I herein give reference to
the accompanying sheet of Drawings illustrative thereof. The shell or exterior
form of the trap may be square, round, or other convenient shape, and the interior of
-the said shell is provided with two traps as shown in Fig 1 which is a cross section
of one form of shell and trap I employ, whilst Fig 2 is front elevation of same
shewing its position fixed within the wall. The form and construction of trap will
be well understood by those conversant with this class of goods. A being the
inlet, B the outlet, and a hinged grate so as to render it easy to get inside for
the purpose of cleaning out. It will be observed that within the shell or box
marked D, are two traps, E and F, both of which are formed with the shell, but in
some cases I introduce a loose or fixed syphon trap as shewn in section Fig 3,
whereby two traps are still formed within the shell.
Instead of using the hinged grate C for cleaning purposes I prefer in some cases
to use a shoe H composed of pot, metal, cement, or other suitable material and
made to slide in and out of an opening made in the trap as shewn in Figª 3 and 6
and in detail Fig 5.
In the outlet pipe B I make an opening, covered by a lid I as shewn in Fig 6
for the purpose of introducing a cleaning rod to clean out the pipes connected
therewith.
In some cases the shell D is made of two parts as shewn in Fig 6, and when the
trap is used outside the upper part may be removed, and a cover placed upon
the lower part as shown in Fig 7 where K is the loose cover.
The outlet of the trap may be connected with the sewer by means of an ordinary
Bocket pipe or a socket pipe, having its end bevilled or rounded, as shewn at L in
Fig 8 fitting into a correspondingly bevilled or rounded socket as shewn at M
whereby a better joint is obtained, and the adjustment of the pipes to the various
angles of the sewer is ensured.
Having thus described the nature of my Invention, and shewn by Drawings
'how the same may be carried into practice, I would have it understood that I do
not confine myself to the precise details of construction herein given, but what I
claim as my Invention and consider to be new is,
'
Firstly. The use and employment of the two traps E and F for the purposes
of preventing noxious gasses escaping therefrom in manner substantially as
shewn,

page_text: Secondly. The use in connection with a trap, of the grates C and H, for the
purpose substantially as described.
Thirdly. The use of bevilled or rounded socket pipes as shewn in Fig 8 for the
purposes explained.
In Witness whereof I the said Edward Green have hereunto set my hand and
seal this nineteenth day of April in the year of our Lord one thousaud
eight hundred and eighty three.
EDWARD GREEN. (L.S.)
