PROVISIONAL SPECIFICATION.
Improvements in Taps and Valves.
I, THOMAS WINTER; of Perseverance Works, Blackburn in the County of
Lancaster, Brass Founder, do hereby declare the nature of this invention to be as
follows:-
.
This invention relates to improvements in taps and valves the object being to
render the tap or valve more durable than heretofore, and to prevent the objection-
able dropping of water of condensation from steam valves by making the valve or
tap steam and water tight.
According to this invention the plug of the valve is made of the ordinary shape,
but in lieu of having one passage way directly through it, the plug is made hollow
and one hole or port is formed near the top of the said plug, and one near the
bottom so that the holes or ports on each side of the plug are not opposite to one
another.
The barrel of the tap or valve is made as ordinary but with the inlet and outlet ·
way or ports one higher than the other so as to correspond with the passage way
or ports in the plug, and the necks of the barrel are slightly curved towards the
inlet and outlet ways.
It will be seen that when the valve or tap is closed nearly the whole circum-
ference of the plug is opposite to the inlet way or port, and to open the valve a
half turn must be given the plug to bring the passage ways or ports opposite one
another and that no steam or water can pass through the valve until the space
between the upper and lower ports is worn as well as the part of the plug linable.
with such ports.

COMPLETE SPECIFICATION.
Improvements in Taps and Valves.
I, THOMAS WINTER of Perseverance Works, Blackburn in the County of
Lancaster, Brass Founder, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to improvements in taps and valves, the object being to
render the tap or valve more durable than heretofore, and to prevent the objection-
able dropping of water of condensation from steam valves by making the valve or
tap steam and water tight.
Such being the nature and object of my said invention, the following is a
complete description of same reference being had to the accompanying drawings in
which:-
Fig. 1 is a sectional side elevation of the tap or valve with the ports open.
Fig. 2 is a sectional side elevation of the tap or valve with the ports closed.
Fig. 3 is a sectional side elevation of a modification of the improved tap or valve
with the ports open.
Fig. 4 is a similar view to Fig. 3 but shewing the ports closed.
According to this invention the plug 1 of the tap or valve 2 is made of the
ordinary shape, but in lieu of having one port or passage way directly through it

page_text: the plug is made hollow as at 3 and one hole or port 4 is formed near the top of
the said plug 1, and one hole or port 5 at or near the bottom, so that the holes or
ports 4, 5 on each side, or on the side and bottom of the plug 1 are not opposite to
or lineable one with the other.
The barrel 6 of the tap or valve 2 is made as ordinary but with the inlet way or
port 7 higher than the outlet way or port 8 or vice versa, so as to correspond with
the passage ways or ports 4, 5 in the plug 1, and the necks 9 of the barrel 6 are
slightly curved towards the inlet and outlet ways 7. 8 so as to allow the water or
steam to pass through freely. It will be seen that when the valve or tap 2 is closed
(see Fig. 2) nearly the whole circumference of the plug 1'is opposite to the inlet
way or port 7 and to open the valve 2 a half turn must be given the plug 1 so as
to bring the passage ways or ports 4. 5 opposite the port or passage ways 7. 8. No
steam or water can pass through the valve 2 until the space 10 of metal between
the upper and lower ports 4. 5 is worn as well as that part of the plug 1 which is
lineable with the ports 7. 8.
In Figs. 3 and 4 the lower port 5 is in the bottom of the plug 1, so that when
the valve or tap is either opened or closed the hollow plug is always full of steam
or water the pressure of which expands the hollow plug, and causes it to fit tightly
in the barrel or body of the tap or valve. This form of the tap or valve is
specially advantageous when used for steam.
The ports or passage ways in the plug and valve are curved, but are of such size
as to be equal to a through way tap.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
A tap or valve in which the ports in the plug are out of line or one above the
other and the inlet and outlet ways are lineable but curved so as to meet the ports
in the plug which are out of line or one above the other as herein described and
substantially as illustrated by the annexed drawings.
