Year: 1876

page_text: LETTERS PATENT to Hartley Wilson, of Halifax, in the County of York,
Cashier, for the Invention of" A NEW OR IMPROVED COMBINED VENTILATING
GULLEY AND TRAP.""
Sealed the 11th July 1876, and dated the 13th January 1876.
PROVISIONAL SPECIFICATION left by the said Hartley Wilson at the Office
of the Commissioners of Patents on the 13th January 1876.
HARTLEY WILSON, of Halifax, in the County of York, Cashier.
IMPROVED COMBINED VENTILATING GULLEY' AND 'TRAP.'"
"A NEW OR
This Invention consists in constructing street gulleys in such manner that they
may act as ventilators, and permit the escape of gases from the drains into the
open air, or may "trap" or confine the said gases within the drains.
The gulley is of ordinary construction with the addition of a pipe connecting
the elbow or bend of the fall or branch pipe with the side of the gulley at or near
the top, this pipe being in a straight line with the branch pipe from the main drain
or sewer. A lid or cover can be applied to the orifice of this pipe, and according as
it is opened or closed the gases will escape from or be confined within the sewer or
drain.
This construction of gulley affords extra facilities for cleaning out the branch
pipes, as by taking the grate from the top of the gulley a cleaning rod can be inserted
through the whole length of the branch pipe, so dispensing with the necessity of
breaking up a portion of the street or road."
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said Hartley Wilson in the Great Seal Patent Office, on the 12th July
1876.

page_text: The gulley is of ordinary construction, with the addition of a pipe connecting the
elbow or bend of the fall or branch pipe with the side of the gulley at or near the
top, this pipe being in a straight line with the branch pipe from the main drain or
sewer. A lid or cover can be applied to the orifice of this pipe, and according as it
is opened or closed the gasses will escape from or be confined within the sewer or
drain.
This construction of gulley affords extra facilities for cleaning out the branch
pipes, as by taking the grate from the top of the gulley a cleaning rod can be
inserted through the whole length of the branch pipe, so dispensing with the necessity
of breaking up a portion of the street or road.
Figs. 1 and 2 of the accompanying Sheet of Drawings represent two methods of
carrying out my Invention.
The same letters of reference refer to the same parts in each Figure.
A is the "gulley" constructed with the ordinary arm B to "trap" in the usual
manner; C is an additional pipe or arm, which may be closed at the point D with
a wooden or other suitable plug or cover. Through this pipe a cleaning rod E may
be inserted, and passed entirely down the branch pipes F into the sewer G, for the
purpose of opening or removing any obstruction from the said branch pipes, and thus
dispense with the necessity of breaking up the road or street, which has hitherto
had to be done when ordinary gulleys have been used. When the pipe C is closed
the gulley "traps" in the usual manner, but if left open the confined air and gasses
are free to pass out of the sewers into the open air, thus securing the ventilation of
the sewers. The pipe C may be moulded with and form part of the gulley, as shewn
in Fig. 2, but I prefer to mould it separate and attach it afterwards by means of
sucket and cement, as shewn in Fig. 1, so that if the pipe C gets broken the whole
of the "gulley "is not rendered useless.
In witness whereof, I, the said Hartley Wilson, have hereunto set my hand and
seal, this Fifth day of July, in the year of our Lord One thousand eight
hundred and seventy-six.
Witness,
A. B. CROSSLEY,
Clerk to Wm. Tasker,
