Improvements in Valves or Cocks used for Regulating the Fow
of Water and other Fluids.
THOMAS BUTTERWORTH WRIGHI, of 74, Brooki ovd Lane, Brown Hill, Birstall,
Gentleman, HENRY WRIGHT of 21, Carlinghow Hill, Batley, Gentleman; and
JOHN WRIGHT, of Bradford Road, Cailinghow, Batley, Overlooker, all in the
County of York, 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.-
We make the valve plug of an improved shape, as shewn in our Patent
No 6893/93, so as to prevent the abrasion and consequent wear as in or ordinary
taps. The washer 18 prevented from unduly expanding when pressure is applied,
by a tube or holder of metal or other suitable niaterial
In order that our invention may be fully understood, we have appended a sheet
of diawings and hereinafter refer to said sheet of drawings
Fig 1 Shows our improved valve plug "A" with our washer of rubber or
other suitable material
Fig. 2 Shows our protector tube or holder "C" made of brass or other suitable
material, which we place around the periphery of both the valve plug "A" and
the washer "B" Fig 1
Fig 3 Shows a top end view of the valve plug "A" with our tube or
holder "C" surrounding it.

Fig 4 Is a bottom end view showing the bottom end of valve plug "A" with
our washer
B" in position and surrounded by our protector tube or holder "C"
Fig. 5 Is a sectional view of the valve plug "A", the washer "B" and the
piotector tube or holder in position.
"
When the handle of the tap is turned in one duection, the pressure of the water
or fluid in the pipe, lifts the valve plug "A up, and allows the water or fluid
to flow, and when the tap handle 18 screwed downwards on in the opposite direc-
tion, pressure is then put on the valve plug with its washer and it is pressed down
onto the seat of the tap and the water or fluid is shut off and prevented from
flowing
Now the washer in ordinary taps coming into contact with the seat of the tap,
is worn away and has to be replaced by another one, but our improved washer
being made of rubber or other suitable material, does not so readily_wear away
because of our invention of a protector tube or holder pait "C" in Fig 2 This
protector wo place around but do not attach to, both the valve plug "A" Fig 1,
and also the washer "B" Fig 1, of rubber or other suitable material By this
means we prevent the undue expansion and consequent abrasion of the
washer "B" Fig 1, when pressure is put on by screwing down the handle of the
tap If thought desirable to more readily permit of the flowing of water or other
fluid, the end of the protector tube or holder might be slightly cogged or corru-
gated, but we prefer to make it with a straight end.

page_text: 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 18:-
A protector tube of metal or other suitable material plaeed 1ound the periphery
of both the valve plug and the flexible washer substantially as illustrated and
described
