page_text: I PHILIP BUCKLEY of Bruntcliffe near Leeds in the county of York Mechanical
Engineer, do hereby declare the nature of this Invention to be as follows :-
The object of my invention is to connect the pipes between the force pump and the
boiler, so as to prevent the water from returning to the pump, and so dispensing with
the ordinary check valve. My union joint consists of couplings with tapered ends so
as to fit into each other, one coupling having a projection against which the nut binds
which secures the couplings together, the space between the projection and the other
end of the coupling may contain an indiarubber ring or other suitable packing
substance, and by screwing up the nut it is perfectly steam tight within the coupling
is preferably a ball valve (or a musheroom or three winged valve may be substituted
for the ball valve, but I prefer the ball valve; above the valve I cast or attach to
the top coupling a bearing in which is tapped a stopper for the ball or other valve,
this stopper is adjustable by means of its screw and nut, so that the amount of the
movement of the ball can be regulated as required; there are also a number of wings
or projections which guide the ball (to and from the stopper) when it is raised from
its seat, between the wings are spaces through which the water can pass. When the
stopper is worn out a new one can be put in at little cost.

page_text: I, PHILIP BUCKLEY, of Bruntcliffe, near Leeds, in the county of York, Mechanical
Engineer, 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:-
The object of my invention is to connect the pipes between force pumps and boilers, 5
so as to prevent the water returning to the pumps, and in such a way as to dispense
with the ordinary check valves

DESCRIPTION OF DRAWINGS.
Fig. 1. is a sectional elevation of my invention.
Fig. 2. is an elevation of my invention.
-
Fig. 3. is a plan of interior of top coupling.
Fig. 4. is a plan of interior of bottom coupling.
My union joints consist of the couplings A and B, with tapered ends so as to fit
into each other, and a projection C on the coupling A against which the nut D
binds which secures the said couplings together, the space E between the projection C
and the end of the coupling B may contain an indiarubber ring or other suitable
packing substance or material, and by screwing up the nut D the joint is made
perfectly steam or watertight.
Within the coupling B is preferably a ball valve F, a mushroom or three winged
valve may be substituted for the ball as preferable. Above the valve F I cast or attach
to the top coupling A a bearing G in which is tapped a stopper H which is adjustable
by means of screw J and nut K. so that the amount of lift of the ball can be regulated
as required.
This stopper H is preferably recessed or dished out to receive the valve ball F when
it is moved up. There are a number of wings or projections L to guide the ball F to
and from the stopper H when it is raised from its seating; between the wings L are
spaces M through which the water can pass.
When the stopper H is worn out or becomes inefficient a new one can be put in at
little cost.
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 I claim is
The construction of union joints for dispensing with check valves substantially as
shown and described.
