Improvements in Valves.
We, CHARLES HIBBERT BERRY, of 16 Heslington Street, Moss Side Manchester,
in the County of Lancaster, Engineer, and FREDERICK ROBERT Putz of 8 and 0
South Parade Manchester in the County of Lancaster, Merchant, do hereby do-
clare the nature of this invention to be as follows:-
The object of our present Invention is to construct and arrange Valves in such
a manner that in the event of a leakage occurring in the seat of the valve when
in use, the leak may be stopped without putting the valve out of use.
For the purpose of our Invention we construct and arrange. in the valve, ap
auxiliary seating and an auxiliary valve, the latter of which is preferably adjust-
able with reference to the main valve. We make the main and auxiliary valve
co-axial, so that they may be simultaneously or separately operated by the rota-
tion of a single hand-wheel or handle.
We may carry out our Invention in various ways, one of which only will be
described as illustrative of the nature of our improvements.
The main valve spindle may be made hollow or in the form of a sleeve within
which the auxiliary valve spindle is contained and within which it is longi-
tudinally adjustable. Normally the auxiliary valve is free of its seating when
the valve is closed. Should a leak occur,. the auxiliary spindle is readjusted so
as to bring the auxiliary valve upon its seating. In this condition, both valves
will be opened and closed by the same act.
It may, of course, be arranged that both valves are normally on their seatings
when the valve is closed, but we prefer that the auxiliary valve should always be
kept as a reserve.
Any or all of the working faces of the valves and their seatings may be
arranged to be renewable or not, as may be desired.

We, CHARLES HIBBERT BERRY, of 16 Heslington Street, Moss Side Manchester,
in the County of Lancaster, Engineer, and FREDERICK ROBERT PUTZ of 8 and 9
South Parade, Manchester, in the County of Lancaster, Merchant, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The object of our present invention is to construct and arrange valves in such
a manner that in the event of a leakage occurring at the seat of the valve when in
use, the leak may be stopped without putting the valve out of use.

page_text: For the purpose of our invention we construct and arrange in the valve an
auxiliary seating and an auxiliary valve the latter of which is preferably ad-
justable with reference to the main valve. We make the main and auxiliary
valve co-axial so that they may be simultaneously or separately operated by the
rotation of a single hand-wheel or handle.
We will further describe our said invention with reference to the accompany-
ing drawing which represents a vertical longitudinal section of a valve constructed
according to our present improvements, but it is to be understood that we may
modify this construction in various ways and that the form shown is to be taken
as being illustrative of our improvements.
In the drawing, A shows the main valve spindle which is made hollow or in
the form of a sleeve within which the auxiliary valve spindle B is contained and
within which it is longitudinally adjustable. The means for this adjustment may
consist in a screwed upper part of the spindle engaged in a nut formed in the
upper part of the hollow spindle A. After the auxiliary spindle has been ad-
justed it may be fixed by means of the lock-nut C. A is the main valve which
may be of any suitable construction, and which, when the valve is closed, is upon
its seating as shown by the drawing. The auxiliary valve B¹ may also be of any
suitable construction and normally does not come upon its seating when the valve
is closed, as shown. In this condition both the valves may be raised and lowered
by the same act, that is to say by rotating the hand wheel D which is fixed upon
the main valve spindle.
In the event of a leakage occurring, the lock-nut C is loosened and the auxiliary
valve spindle B is turned for instance by means of a key or spanner fitting upon
its square end E, until the valve B' comes closely upon its seating F, thus stop-
ping the leak. It is then relocked by the nut in this position.
It may of course be arranged that both of the valves are normally on their seat-
ings when the valve is closed but we prefer that the auxiliary valve should always
be kept as a reserve when not in actual use temporarily to prevent a leakage."
Any or all of the working faces of the valves and their seatings may be arranged
to be renewable or not as may be desired.
The main valve spindle may be provided with a stuffing box and gland on
the tubular part I which has an internal screw thread in which a correspondingly
screwed part of the main spindle works. The cap G may be screwed into a
tubular part of tho casing H which latter may have any convenient form.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In a valve, the combination and arrangement of a main valve and spindle
with an auxiliary valve and spindle and a separate seating for each valve, sub-
stantially as and for the purpose hereinbefore described and as illustrated by the
accompanying drawing.
2. In a suitabile casing, a main valve having a hollow spindle, an auxiliary
valve with its spindle adjustable within the main valve spindle and a separate
seating for each valve, constructed substantially as and for the purpose herein-
before described and as illustrated by the accompanying drawing.
