Year: 1876

page_text: LETTERS PATENT to John Lanyon, of Belfast, in the County of Antrim, in
Ireland, Civil Engineer and Architect, for the Invention of "IMPROVEMENTS
IN WATERCLOSETS AND IN VALVES USED THEREWITH, AND FOR OTHER PUR-
DOSES"
Sealed the 16th May 1876, and dated the 29th January 1876.
PROVISIONAL SPECIFICATION left by the said John Lanyon at the Office
of the Commissioners of Patents on the 29th January 1876.
JOHN LANYON, of Belfast, in the County of Antrim, in Ireland, Civil Engineer
and Architect. "IMPROVEMENTS IN WATERCLOSETS AND IN VALVES USED THERE-
WITH, AND FOR OTHER PURPOSES."
My Invention consists in the use of a valve having a stand-up flange, so as to
form a cup or bowl, and retain the flush water or a portion thereof in the basin of
the closet, and being enclosed in a trunk or stench trap through a perforation or
perforations, in which a jet or jets of water may be directed against the valve when
opened for the purpose of cleansing same.
A tube may be employed to convey foul air or gases from the trunk or stench
trap into the ventilating pipe or other passage to the open air.
I also adapt the same valve to pumps and other objects of a similar nature.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Lanyon in the Great Seal Patent Office on the 29th July 1876.
JOHN LANYON, of Belfast, in the County of Antrim, in Ireland, Civil Engineer
and Architect. "IMPROVEMENTS IN WATERCLOSETS AND IN VALVES USED THERE-
WITH, AND FOR OTHER PURPOSES."
The said Invention is a development and extension of portion of an Invention
for "Improvements in Ventilation, and in Apparatus therefor," which Her said
Majesty by Her Letters Patent, bearing date the Thirty-first day of July, One
thousand eight hundred and seventy-five, in the Thirty-ninth year of Her reign,
for Herself, Her heirs, and successors, gave and granted unto me, the said John
[Price Gd.]

page_text: Lanyon, my executors, administrators, and assigns, or such others as I or they
might agree with, Her special license to make, use, exercise, and vend within the
parts and places aforesaid, and of which I have by an instrument in writing under
my hand and seal, duly filed in the Great Seal Patent Office, already described and
ascertained the nature and manner of performance.
My present Invention relates to waterclosets, jaw boxes, slop basins, washing
basins, baths, pumps, and other hydraulic engines, or apparatus of a similar nature,
and for its object the more perfect shutting or stoppling of the escapement
aperture of such apparatus. Its chief application is, however, to waterclosets, jaw
boxes, slop basins, and washing basins.
My Invention consists in the combination of a pan and valve, which I call a pan
valve, to be used immediately under the lower or escapement aperture of the closet,
box, basin, or other vessel.
The face of my pan valve is constructed according to the ordinary forms of closet
valve, and may be adapted to the form employed in any of the vessels or apparatus
referred to. The flange is shaped like the rim of a cup, bowl, or inverted bell, and
its diameter increases as it recedes from the face of the valve. When closed the
flange encases the rim of the escapement aperture, and retaining the water therein
makes the joint substantially if not absolutely impermeable.
The pan valve is enclosed in a large and roomy metal box, trunk, or stench trap,
and through a perforation or perforations in this box, trunk, or trap a jet or jets of
water may be introduced for the purpose of flushing and cleansing the pan valve
when open and removing any impurity or substance which might intercept or pre-
vent its closing, and furnishing a retentive or impermeable joint.
The box, trunk, or trap may also be provided with a tube, pipe, or extracting
flue to convey to the open air any deleterious or offensive vapours or gases arising
or collected therein.
And in order that the said Invention may be more fully understood I shall now
proceed to refer to the transverse sectional Drawing on the Sheet hereunto annexed,
showing the application thereof to a watercloset.
A is a closet basin of ordinary construction; a is the pan valve, having a flange
resembling the rib of a cup, bowl, or inverted bell, and when closed encasing the
rim of the escapement aperture. The face of the pan valve is furnished with a
raised hoop or circular ridge, which when closed sinks into a packing or cushion of
'india-rubber let into a groove in the edge of the rim of the escapement aperture.
b is the metal box, trunk, or stench trap; c is a perforation through which a jet of
water is introduced for the purpose of flushing and cleansing the pan valve when
open and is a tube, pipe, or extracting flue to convey deleterious and offensive
vapours and gases to the open air.
Having now described the nature of the said Invention and in what manner
the same is to be performed, I would have it to be understood that I do not claim
the use of pan or valve, box, trunk, or trap, tube, pipe, or extracting flue, nor of
water for flushing or otherwise, except when the same are constructed or introduced
specially and employed as, herein described, nor do I claim the use of any of the
separate mechanical parts which form the compound apparatus used by me; but I
claim,
First. The use in waterclosets, jaw boxes, slop basing, washing basins, pumps, and
other hydraulic engines and apparatus of a pan valve and a box trunk or trap con-
structed and employed substantially as described and shewn in the Drawing here-
unto annexed.
Secondly. The use in waterclosets, jaw boxes, slop basins, and washing basins of
water introduced and applied substantially as described and shewn in the Drawing
hereunto annexed.
Thirdly. The construction and application of a pan valve such as is shown in the
Drawing hereunto annexed in the manner and for the purposes herein-before
described.

page_text: And, Fourthly. The combination and arrangement of parts constituting the com-
pound automatic apparatus herein before mentioned, constructed, and applied
substantially in the manner and for the purposes herein-before described.
.
In witness whereof, I, the said John Lanyon, have hereunto set my hand
and seal, this Twenty-seventh day of July, in the year of our Lord One
thousand eight hundred and seventy-six.
Signed and sealed in presence of
HUGH HYNDMAN,
Belfast,
Solicitor.
