Year: 1879

page_text: LETTERS PATENT to Thomas Simcox, of Halifax, in the County of York,
Ironfounder, for the Invention of "AN IMPROVED STREET GULLEY' OR
TRAP."
Sealed the 4th July 1879, and dated the 8th January 1879.
PROVISIONAL SPECIFICATION left by the said Thomas Simcox at the Office
of the Commissioners of Patents on the 8th January 1879.

IMPROVED STREET GULLEY' OR TRAP."
"AN
This Invention consists in forming a street gulley, simple in its construction,
capable of being easily cleaned, and forming a perfect trap. The gulley is constructed
of a box or vessel of suitable shape having two compartments therein formed by a
partition, but does not extend to the bottom of the box. A lid is placed on the top
of the box, one half of which is perforated or made as a grate communicating with
one of the compartments of the said box. Water and street refuse passing over the
lid will run through the grate into one compartment, passing under the partition
into the next compartment, and on reaching a certain height, the water is allowed
to escape through an elbow pipe communicating with the main sewer of a street.

IMPROVED STREET GULLEY' OR TRAP."
"AN
This Invention consists in forming a street gulley, simple in its construction,
capable of being easily cleaned, and forming a perfect trap.
The gulley is constructed of a box or vessel of suitable shape having two com-
partments therein formed by a partition which does not however descend to the
bottom of the box. A lid is placed on the top of the box, one half of which is per-
forated or made as a grate communicating with one of the compartments of the
said box.
Water and street refuse passing over the lid will run through the grate into one
compartiment, passing under the partition into the next compartment, and on
reaching a certain height the water is allowed to escape through an elbow pipo
communicating with the main sewer of a street.
In order that my Invention will be more readily understood I have hereto
annexed a Sheet of Drawings marked with figures and letters of reference illustra-
tive thereof. Fig. 1 is an end view of my improved gulley; Fig. 2 is plan view of
sama; and Fig. 3 is vertical sectional elevation. A is a box, which may be con-
structed of iron, with a partition B cast therein dividing the box into two com-
partments a, b. Over the box is placed a rectangular frame C, also having a
partition c in a line with the partition B.
Over the compartment b is placed a lid D provided with a handle, and over this
is a second lid E fitting closely within the rectangular frame C, one half of the said
lid E being perforated or in the form of a grate and the other part being solid.
The box A is provided with an outlet or overflow pipe F.
Water and street refuse passes through the grato into the compartment a, and
passing underneath the partition B, the water and lighter portions of refuse rise in
the compartment b until they reach the overflow pipe F communicating with the
sewer, the heavier refuse or sediment lodging in the bottom of the box.
When this has accumulated to such an extent as to interfere with the free passage of
water under the partition B the lids can be removed and the box cleaned out. The
lid B prevents any odour from rising from the sewer, being made to fit closely on
its seating.
Having thus described the nature of my said Invention, and shown by Drawings
how the same is to be or may be performed or carried into effect, I would have it
understood that I do not confine myself to any particular form or material, but
that I claim as my Invention the general construction and arrangement of street
gulleys or traps, substantially as herein shewn and described.
In witness whereof, I, the said Thomas Simcox, have hereunto set my hand
and seal, this Fifth day of July, in the year of our Lord One thousand
eight hundred and seventy-nine.
THOMAS SIMCOX. (L.S.)
