Improvements in Draw-off Valves for Water Carts, Barrels, Tanks,
Cisterns, and such like Vessels.
I JOHN SAMUEL CONDER and I WILLIAM CONDER Builders and Wheel-
wrights of Hildersham in the County of Cambridge 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 draw-off valves for water or other liquids for water
carts, tanks, barrels or other receptacles to which an outlet tap or valve is usually
provided, and is more particularly applicable to vessels that are exposed to frost
as the valve seating being placed at the extreme inside end of the tap when the
orifice is closed no water or other liquid remains in any part of the tap. This
invention is also suitable for drawing off liquids that contain solid matter as the
outlet or spout is so placed that any obstructing matter can be readily removed.
We make a hollow cylinder A of any suitable metal open at one end which said
end is flanged B and drilled through the flange B for bolting or screwing to the
vessel C. The other end of this hollow cylinder A is closed excepting a hole
drilled in the centre. This hole is screwed to receive a threaded rod D, the end
of this rod D outside the cylinder A is cranked E and fitted with a handle F and
to the end of the said rod D that is inside the cylinder A a boss or clack G of
metal is fitted by a swivel joint H in such a manner that when the rod D is turned
by means of the handle F the clack G is moved backwards and forwards inside
the cylinder A, the said boss or clack G being kept from turning by two
projections Fig. 2. 1. on its outer edge fitting into corresponding grooves Fig. 2.
1 running the length of the inside of the cylinder A. The outlet hole in the
vessel C is inade of a smaller size than the inside diameter of the flanged
cylinder A, and is fitted with a collar K of india-rubber, leather, or other suitable
material, this collar K is perforated in the centre to correspond with the outlet
hole J in the vessel C and the outer diameter of this collar K is made to correspond
with the outside diameter of the flange B on the hollow cylinder A before
mentioned. The said collar K thus serves two purposes it makes the joint between
the tap or valve and tho vessel C, and also makes 'the valvo seating against which
the before-mentioned clack G is screwed to close, or unscrewed to open the orifice.J
in the vessel C, by turning the haudle F on the threaded rod D. To the lower
side and at the end close to the flange B of the before mentioned hollow cylinder A
is fitted another hollow cylinder L or spout projecting forwards and downwards to
conduct the water or other liquid when the valvo is opened. This spout L is so
fitted that when the valve is opened a straight rod can be inserted up the said
spout L into the vessel C, in this way any obstructing substance can be readily
removed. When the vessel C is of such shape or material that a proper senting
cannot be made on the vessel, a metal or other seating is provided.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
(1.) The position of the valve seating K at the extreme inside end of the tap.
The using one collar K only to make the joint between the tap and the

page_text: (3.) The straight shape and the downward and forward position of the
spout L.
