IMPROVEMENTS IN VALVE COCKS
Year: 1885

page_text: I THOMAS DIPPLE of 69 Bloomsbury Street Birmingham in the County of
Warwick, Manager of Works do hereby declare the nature of my invention for
"IMPROVEMENTS IN VALVE COCKS" to be as follows, that is to say :-
My Invention has for its object improvements in valve cocks which are so
constructed as not to be liable to become derranged in their parts so as to cause
waste or leakage. I will explain my invention as applied to an ordinary tap
suitable for cold or hot water and other fluids steam or gasses.
The body of the cock or tap in general appearance is much like those now in use
that is with the stuffing box valve stalk and handle. In the case of my cocks or
taps the valve stalk which is one with the handle passes down the stuffing box and
terminates with a long screw at the point.
At the bottom of the stuffing box I fit a conical metal ring for the purpose of
relieving any extra pressure brought upon the shoulder of the stalk and the bottom
of the stuffing box so that the valve handle always turns easily. Immediately
under the bottom of the stuffing box is the passage leading out to the point of the
tap and underneath this passage is another shoulder formed under which is a
projecting face against which the valve works and the passage is here enlarged to
the bottom for the purpose of receiving the valve. The valve is entered from the
bottom and is specially made with a face having a groove formed therein into
which it is fitted a rubber or other suitable flexible ring so that when the valve is
lifted against the projecting valve facing the said projection exactly corresponding
with the recess in the valve compresses the flexible ring over its whole surface and
any tendency to spead or expand is entirely prevented by the sides of the recess
and by this means the facing is most easily kept tight without much renewal; or
the projection and the groove may be so nicely fitted and ground together as not
to require any ring. The passage communicating with the supply leads out under
the second collar aforesaid in the enlarged chamber in which the valve works.
The valve is provided with a deep recess which is tapped to agree with the
thread upon the end of the stalk. The back of the valve is provided with a
projecting square shank or other equivalent arrangement for holding the valve
secure against turning. This square or other equivalent guide is held by the
bottom cap which has a corresponding hole or arrangement in which the square or
other shank slides. Thus when the handle and spindle is turned the valve being
prevented from turning is brought up against the face aforesaid or carried down-
wards as it may be desired thus opening and shutting the way most effectively
with great ease.

J, THOMAS DIPPLE of 69 Bloomsbury Street Birmingham in the County of
Warwick Manager of Works, do hereby declare the nature of invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention has for its object improvements in valve cocks which are so
constructed as not to be liable to become derranged in their parts so as to cause
waste or leakage. I will explain my invention as applied to an ordinary tap
suitable for cold or hot water and other fluids steam or gasses.
The body of the cock or tap in general appearance is much like those now in use
that is with the stuffing box valve stalk and handle. In the case of my cocks or
taps the valve stalk which is one with the handle passes down the stuffing box and
terminates with a long screw at the point-At the bottom of the stuffing box I fit
a conical metal ring for the purpose of releiving any extra pressure brought upon
the shoulder of the stalk and the bottom of the stuffing box so that the valve
handle always turns easily.
Immediately under the bottom of the stuffing box is the passage leading out to
the point of the tap and underneath this passage is another shoulder formed under
which is a projecting face against which the valve works and the passage is here
enlarged to the bottom for the purpose of receiving the valve. The valve is
entered from the bottom and is specially made with a face having a groove formed
therein into which is fitted a rubber or other suitable flexible ring so that when
the valve is lifted against the projecting valve facing the said projection exactly
corresponding with the recess in the valve compresses the flexible ring over its
surface and any tendency to spread or expand is entirely prevented by the sides of
the recess and by this means the facing is most easily kept tight without much
renewal or the projection and the groove may be so nicely fitted and ground
together as to not require any ring. The passage communicating with the supply
leads out under the second collar aforesaid in the enlarged chamber in which the
valve works. The valve is provided with a deep recess which is tapped to agree
with the thread upon the end of the stalk. The back of the valve is provided
with a projecting square shank or other equivalent arrangement for holding the
valve secure against turning. This square or other equivalent guide is held by the
bottom cap which has a corresponding hole or arrangement in which the square or
other shank slides Thus when the handle and spindle is turned the valve being
prevented from turning is brought up against the face aforesaid or carried
downwards as it may be desired thus opening and shutting the way most
effectively with great ease.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have
illustrated three examples of these taps which I call the Patent Fidus Valve Tap
the one being for cold water the other for spirits the other for hot water in such
positions as ranges and it will be clearly understood that the design may be
considerably varied without departing from the nature of the invention,

page_text: Figure 1-Is the side elevation of a Tap such as is most suitable for Spirits
having a contracted nose or outlet A and a handle B which admits of very nice
adjustment.
Figure 2-Is the side elevation of a cold water tap much the same in
appearance as those now in use even to the hand C and the nose or outlet D is
also much the same. Both this and the spirit tap are fitted with the usual screw E
for connection to the barrel or other vessel.
Figure 4-Is the side elevation of a tap particularly suited for hot water or
such positions as Kitchen ranges and is fitted with the locking washer and long
screw G in order that a joint may be made inside the boiler.
Figure 3-Shows the inside details of the spirit and cold water taps Figure 1
and 2 and which will be easily understood on reference thereto H is the friction
ring at the bottom of the stuffing box and K is the valve which bears against the
seat M and N is the washer or other face of the valve into which the corresponding
projection upon the face fits. By taking out the plug P the valve can be removed
from the inside and then the valve stalk R lifts out from the top. The part K¹ of
the valve K. Figures 1, 2 and 3 is square or other equivalent shape to prevent it
from turning as it rises and falls by the action of spindle R and screw thread r².
Figure 5: merely shows the details of the modifications necessary for the hot
water tap where the valve and seating is reversed and the plug P also becomes the
spout S. The valve K in this case has the projection and the ring is in a recess in
the seat which answers the same purpose to prevent it from turning the valve has
two recesses which slide over projections cast inside the body of the valve casing
as shown by the cross section W which prevents it from turning as the screw 7¹ is
turned and it therefore rise and falls upon the seat.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The improvements in valve cocks which are suitable for spirits or cold or hot
water having a valve K operated through a stuffing box substantially as herein set
forth.
