APPARATUS. FOR REGULATING THE SUPPLY OF WATER FOR FLUSHING PURPOSES IN
ORDER TO PREVENT WASTE, PARTS OF WHICH IMPROVED APPARATUS ARE ALSO
APPLICABLE TO OTHER PURPOSES."
This Invention has for its object to regulate the supply of water to closets and
other places so as to prevent waste.
To carry out such improvements I proceed as follows:-To any suitable cistern
I affix two valves placed one above the other, and hereafter terined the supply and
let off valves.
'
The upper or supply valve consists of a T piece the shank whereof is furnished
externally with a suitable screw thread for connecting the same both to the cistern
and water main, while the head thereof is fitted with two cupped leathers placed
one at each end and held in position by suitable nuts. A parallel hollow piston
works up and down vertically through such cupped leathers and is provided with
apertures. When the piston is down these apertures are between the two cupped
leathers and are nearly opposite the water way in the tap or valve, thus allowing
the water to flow into the cistern, but when the piston is raised such apertures are
either above or covered by one of such leathers, thus arresting the flow of the
water.
The lower or let off valve consists of a cylinder fixed under the supply valve
in the bottom of the cistern. Suitable slots or other apertures are formed in the
upper portion of such cylinder which is inside the cistern, through which the water
escapes, as presently mentioned.
Attached to the lower end of the before mentioned piston rod is a spindle the
upper end of which is formed hollow, and has an orifice therein through which the
water flows into the cistern, while its lower end is provided with a flange and nut,
and fitted with a cup leather.
Such spindle slides up and down within the cylinder, and when below the
apertures formed in the upper part of the cylinder the water is held in the cistern,
while when they are above such apertures the water escapes through the latter and
thus flushes the closet or other place.
Both the spindle and piston are actuated by a weighted lever conveniently fixed
above the supply valve.

page_text: An ordinary ball and lever is also attached to the piston, by the action of which
it is raised when the cistern is being filled with water.
The operation of my Invention is as follows:-Upon the water flowing into the
cistern through the supply valve the ball and lever are raised and the apertures in
the piston are either carried above or covered by one of the cupped leathers in the
supply valve, thereby cutting off the supply until the lever is pulled, when the
spindle and cup leather in the lower or let off valve are raised above the apertures
formed in the upper portion of the cylinder, and thus allow the water to escape and
flush the closet or other place.
I would here remark that my improved supply valve may also be advantageously
used as a buoy valve, as owing to its particular construction and the perfect
equilibrium resulting therefrom it is impossible that it should be opened however
powerful the pressure of the water may be.
