Year: 1884

page_text: FACTIONAL SPECIFICATION.
I GEORGE MACFARLANE of 7A Fourth Avenue, Queens Park Paddington in the
County of Middlesex Plumber do hereby declare the nature of my invention for
FLUSHING OF HOUSE SINK WASTES AND THE FLUSHING OF WATER CLOSETS AND
DRAINS to be as follows:
This Invention has for one of its objects the better means of flushing water
closets or Sinks by what is known as the Syphon Flushing Cistern. I prefer to
use what is known as the "leg syphon" that is an inner tube running to bottom
of cistern and entering partly the portion of outlet fitted to bottom of cistern at
which point I insert a valve seating composed of leather or other suitable material.
The outer syphon pipe I fix to the inner tube by soldering or otherwise fitted with
an eye on top connected with an ordinary lever pulling over the front of cistern
in connection with a chain pull by which means when momentarily pulled admits
of a quantity of water through the said valve into the service pipe thus creating
the syphon and ensuring the said quantity of water contained in Cistern to pass.
through the service pipe.
prefer to use in connection an ordinary Ball valve fitted to side of cistern
(cranked) and bent forming a vertical inlet with a provision for overflow made in
the said cistern or otherwise. I prefer to make the Syphon in Brass Copper or
other suitable material with bottom portions screwed to Cistern or fixed with an
ordinary brass standard with back nut addptable to any cistern fitted with a cap
and lining, the said cistern chamber to be made of cast or wrought iron rectangular
or angular back with polyglon front galvanized or coated with a non-corrosive
solution or made in strong zinc or wood lined with lend or other suitable material.
I further prefer to use the above described Syphon fitted in other forms for the
periodical flushing of Urinals mechanically or automatically by the aid of a float
arrangement or by the aid of a mechanical counterbalance revolving on an axis
itted to side of cistern with a perforated receptacle which when partly filled with
water sinks thus raising the syphon tubes admitting a quantity of water into the
ervice pipe and creating the syphon as before described, also for the periodical
lushing of drains.

page_text: I GEORGE MACFARLANE of 7 Fourth Avenue Queens Park Chelsea in the
County of Middlesex Plumber do hereby declare the nature of my Invention for
IMPROVEMENTS IN FLUSHING APPARATUS FOR WATER CLOSETS URINALS AND DRAINS,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
My said Invention has for its object the better means of flushing W.C's or Sinks
by what is commonly known as the Syphon Flushing Cistern by which means the
contents of the said cistern is discharged rapidly through the outlet pipe I prefer
to construct my Syphon with an inner Tube running to bottom of cistern and
connected to Flushing pipe with a union and fitted with guides for outside Tubo
to work on.
The Top of Inuer Tube is carried to within about two inches of the
surface of the water at which point I insert a Valve. The upper portion of inner
Tube is fitted with a seating of leather or Indiarubber and terminates with three
projecting arms which catches on an inner flange of the outside Tube. The outside
Tube is fitted with an eye on top attached to an ordinary lever which when
momentarily pulled admits of a quantity of water through the Valve into the
Flushing Pipe thus creating the Syphon And in order that my said Invention
may be fully understood I will now proceed more particularly to describe same and
for that purpose shall refer to the several letters on my explanatory drawing
attached, the same letters of reference indicating corresponding parts in the
corresponding letters.
Letter A is a vertical section of syphon cistern B is the Inner Tube of Syphon
C is the Valve on top of Inner Tube inside
passing through cistern bottom
cistern D is the top portion of Inner Tube fitted with three guides and valve
seating and lead weight to keep valve in position and three projecting arms E is
the outer Tube with eye on top attached to lever and Inner flange for projecting
arms of top portion of Inner Tube to catch against when pulling the lever to open
Valve C which admits a quantity of water and readily charges the Syphon F. F is
the Cast iron overflow with screwed connection at bottom of cistern.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
my claim is:-
1. The peculiar construction of Syphon Flushing Apparatus substantially a
herein before described and illustrated by my Drawing.
2. The insertion of the Valve on the Inner Tube in close proximity to the surfac
of the water thus minimising the resistance in the action of the Syphon and
making the Syphon more sensitive in its action.
Dated this 1st day of December 1884.
