PROVISIONAL SPECIFICATION.
Improved Means and Appliances for Freeing and Maintaining such
Freedom of Water from Pipes during Frosty Weather, or for
Shutting Off the Flow during Repairs to Pipes.
We, ALEXANDER RUSSELL PULLING, of 19 Garlick Hill, City of London,
Merchant, and FRANCIS JAMES RIVOLTA, of 16 Broad Street, Bloomsbury,
County of London, Tobacco Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improved means and appliances for freeing and
maintaining such freedom of water from pipes during frosty weather, or for
shutting off the flow during repairs to pipes.
For the purpose of our invention, we hinge or otherwise secure a plug or similar
device to or near the outlet nozzle in a water tank or cistern to close the same
after release of a chain from a hook or catch which during warm or ordinary
seasons lift and keep the plug from falling on to the nozzle to close it.
The invention is also applicable for closing the tank or cistern outlet nozzle
during repairs to pipes, the water in the pipes being then drawn off.
Dated this 16th day of December 1895.

Improved Means and Appliances for Freeing and Maintaining such
Freedom of Water from Pipes during Frosty Weather, or for
Shutting Off the Flow during Repairs to Pipes.
We, ALEXANDER RUSSELL PULLING, of 19 Garlick Hill, City of London,
Merchant, and FRANCIS JAMES RIVOLTA, of 16 Broad Street, Bloomsbury,
County of London, Tobacco Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to improved means and appliances for freeing and
maintaining such freedom of water from pipes during frosty weather, or for
shutting off the flow during repairs to pipes.
For the purpose of our invention, and as we show in the annexed sectional
elevation, we binge or otherwise secure a plug or similar device A to or near the
outlet nozzle B in a water tank or cistern C to close the same after release of a
chain D froin a hook or catch E which during warm or ordinary seasons can keep
the plug A from falling on to the nozzle B to close it.
The invention is specially applicable for closing the tank or cistern outlet nozzle
during repairs to pipes, the water in the pipes being then drawn off. A vent pipe F
is fitted to the nozzle.

page_text: The drawing represents our apparatus complete as we propose to construct it
and which after repeated trials has been found to be the most reliable and
efficient.
The plug proper is composed of flexible closing valve a secured between two
washers b, c, by a screw bolt d, the valve a having its larger diameter free to bend
upwardly or downwardly and so adapt itself to fit the edge e of the nozzle
extension f-which is made funnel shape on the inside so that the valve a can enter
and obtain a firm contact seating on and slightly in the top end of the extension f
and so prevent leakage. The depth to which the valve a can enter is more or less
determined by the weight g, this being also fixed by the bolt d secured at the end
of the lever hinged at i to the tail end j of a plate k, the forward end of which
is shaped like a collar to rest upon a shoulder m of the nozzle piece B, and on
which it is secured by the nut n. The collar can be turned circularwise on the
nozzle piece B to any angle and be there locked by the nut n.
We have shown the nozzle piece B, f, screwed on to the stand up portion p of
the draw off pipe as is usual with galvanized iron tanks and in some cases with
lead and also with zinc lined cisterns where the connection 7 is provided with a
flange and a nut s.
The adjustment of the plate k and lever / adapts it for any position in a tank or
cistern and permits of the chain being so set and also its pulley t that the ring u
and catch hook E can be arranged for easy manipulation.
The invention will sometimes be found of service for flushing purposes, as by
keeping the valve closed until the tank or cistern is fully or sufficiently full and
then lifting the valve, a powerful rush of water will clean out a drain and the tank
or cistern quickly emptied.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. The hinged apparatus shown on the annexed drawings and constituting a valve
for closing the.out or down flow from a tank or cistern operable in the manner and
for the purpose described.
2. In a hinged apparatus of the kind described, the particular build up of the
valve proper a, b, c, d, g, with the free flexible larger diameter portion of the
valve a, as set forth and shown.
