Improvements in Cocks or Valves for Controlling the Passage of
Fluids, Applicable also as Closures for Bottles or for other
Analogous Purposes.
I WILLIAM YOUNG of 12 Ansdell Road Peckham in the County of Surrey
Engineer do hereby declare the nature of my said Invention to be as follows:-
-
This Invention has for its object to provide cocks or valves for controlling the
passage of fluids or for use as closures for bottles or for analogous purposes which are
very durable and efficient always maintain a tight joint and are more easily worked
and cleaned than are ordinary stop cocks or valves or the like. I make the casing of
a conical form and I make the internal part (which works therein by rotation) hollow
and of a corresponding conical form to fit into the casing. The passage for fluid
through the valve is effected by openings through the hollow plug and the casing. By
rotating the hollow plug these openings can be made to coincide to open the valve or
be turned from opposite each other so as to close the passage for fluid. The fluid
entering the hollow internal part and pressing against the closed inner end thereof
keeps the internal part in close contact with the casing which casing is fixed by a
flange or other suitable fastening to the boiler or other article with which it is used.
When the device is used as a closure for bottles or the like the lower end of the
hollow internal part may be closed and a bye-pass be formed from the part of the
bottle below the valve up to the opening through the casing so that when the opening
through the internal part is made to coincide therewith the contents of the bottle or
the like pass out. The pressure of the gases upon the closed end of the internal part
keeps the joint tight. The valve or closure may be fitted in the bottle by a fastening
consisting of lugs on the external part or casing passed down through slots in the neck
of the bottle and then turned sideways under projections in the said neck and this
mode of fastening may be applied also in other cases for securing the valve or
closure.

Improvements in Cocks or Valves for Controlling the Passage of
Fluids, Applicable also as Closures for Bottles or for other
Analogous Purposes.
I WILLIAM YOUNG of 12 Ansdell Road Peckham in the County of Surrey 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 :
This Invention has for its object to provide cocks or valves for controlling the
passage of fluids or for use as closures for bottles or for analogous purposes which are
very durable and efficient always maintain a tight joint and are more easily worked
and cleaned than are ordinary stop cocks or valves or the like.
The conical plugs of cocks or valves as hitherto constructed are liable to jam or
become fixed in the casing by the pressure to which they are subjected so as to require
great force to turn them this is owing to the limited angle to which they are coned.
According to my invention I make the casing of a conical form and I make the
internal part (which works therein by rotation) hollow and of a corresponding conical
form to fit into the casing but I make the angle of the cone and casing such that the
pressure acting on the plug will not cause it to jamb or stick but will admit of it
being moved with very little power. The passage for fluid through the valve is effected
by openings through the hollow plug and the casing. When the device is used as a
closure for bottles it may be made in Glass porcelain or other suitable material.
Figure 1 of the accompanying drawings represents in vertical section a cock or
valve constructed according to my invention for drawing off liquids. Figure 2 is a
similar view illustrating a modification which is essentially applicable as a ball cock or
valve and Figure 3 illustrates my invention as applied to a bottle from which its
application to analogous purposes will be readily understood.
Referring to Figure 1, A is the plug of the cock which is made hollow and with a
passage a corresponding to a passage in the casing B in which the plug turns. This
plug is of a conical form as is also the casing in which it turns the angle of which
cone should be sufficiently great to ensure that the plug shall not jam or stick in
the casing when subjected to the pressure to which it is exposed, whilst the pressure
which acts in the interior of the plug always maintains a liquid tight joint between
the conical surface of the plug and the casing.
It has been found in practice that in order to prevent jamming the angle of the
side of the cone with the base should not be less than 13 degrees but it may be made
to any other greater angle desired-In the modification illustrated in Figure 2 for
example the plug A is only slightly dished, the casing B being similarly formed to
correspond so that the friction between the two parts is reduced to a minimum whilst
the pressure exerted on the inner conical surface of the plug always maintains a liquid
tight joint between the plug and its case.

page_text: The plug A in both the arrangements illustrated by Figures 1 and 2 may be
rotated by a handle C, as shewn in Figure 1 and may be employed for drawing off
water from cisterns, domestic boilers or for any other purpose for which it is applicable
To draw off liquid the plug is turned so as to cause the openings a and b in the plug
and its case to coincide or come opposite each other, the said openings being turned
from opposite each in order to stop the flow-The cock may be fixed to the cistern,
supply pipe or other article with which it is used by screwing it thereto by the part o
or it may be attached in any other convenient manner. When employed for govern-
ing the flow of liquid into a cistern the valve is secured to the service pipe and the
plug is fitted with a ball or other float so that as the liquid rises in the cistern the float
will rise and turn the plug A so as to cut off the passage through the opening a and b
and prevent the admission of liquid to the cistern-As the liquid is discharged from
the cistern the float will descend so as to cause the openings a and b to coincide and
admit more water to the cistern.
When my invention is employed as a bottle stopper the device may be made in glass,
porcelain or other suitable material and when employed with bottles containing gaseous
liquids the pressure of the gases acting on the interior of the plug keeps the point
between the said plug and its case liquid tight-A convenient way to fix the stopper
in the mouth of the bottle is to provide the interior of the neck of the bottle with
slots or recesses d and projections e as shewn in Figure 3 and forming on the stopper
projections d'and recesses e¹ to correspond therewith so that by passing the projections
on the stopper down the slots or recesses d in the neck of the bottle and then giving
a partial rotation to the stopper so as to cause the projection thereon to engage
beneath the projections e in the neck of the bottle the stopper will be securely retained
in the neck of the bottle-When it is required to draw off the liquid from the bottle
the plug A may be turned by means of the milled head or handle so as to cause the
opening a in the plug to correspond with or come opposite the opening in the case B
whereupon the liquid will pass out of the bottle. The outflow of the liquid may be
readily cut off by turning the plug so as to bring the opening from opposite each
other.
Having now described and particularly ascertained the nature of my invention
and the manner in which the same is to be performed I wish it to be understood that
I do not claim in cocks or valves the use of conical hollow plugs generally but what I
claim is
In cocks or valves for controlling the flow of fluids a conical hollow plug working
in a corresponding conical casing angled as described and provided with openings for
the passage of the fluid substantially as and for the purpose hereinbefore described
with reference to the accompanying drawings.
