Improvements in Ball, Bib, and other Cocks and valves.
Year: 1887

I JAMES HOOKHAM of No. 5 Gildredge Road Eastbourne in the County of Sussex
Builder do hereby declare that I am in possession of an invention for IMPROVEMENTS
IN BALL BIB AND OTHER COCKS AND VALVES 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 Improvements in Ball, Bib and other Cocks and
valves and consists in arranging that part for closing the supply of a wedge or conically
shaped piece to be acted upon by a screw or lever according to the particular require-
ment In the specification of a former Patent granted to me No. 9336 A.D. 1885 I
described a similar method of closing the said inlet but my present improvements
relate to further practical alterations which I have found advantageous in connection
with the said invention.
In the former specification illustrated and described a ball valve having an
horizontally sliding wedge valve but according to my present improvement I find that
such valve may be actuated in a "ball valve "by the float in a vertical manner thus
making the cock more compact than that shewn in my former Patent before referred to-
In lieu of the wedge before described in some cases I would have it understood thai.
the same objects may be effected by employing a conical valve and seating-the said
valve having an annular packing of soft metal, india rubber, valcanite, asbestos or
other suitable material for the special requirements i.e. Steam, gas, water, and other
fluids.
In my former Patent I described with reference to the drawing accompanying the
said specification the opposite side to that of the inclined valve seating provided with:
an horizontal back for the lateral valve or a vertical one for a vertically actuated valve
I have however found that the back may be tapered so that it may be of a wedge shape
to further assist in effecting a perfect closure.
In adapting these improvements it has been found that each side of the valve may
be provided with the soft metal or other suitable seating as before described with
reference to the conical valve and such seating in wedge shaped valves having a flat
face are advantageously made circular to correspond with the section of the inlet such
seating being secured in a corresponding recess in the said valve.

page_text: I will now proceed to describe my invention with reference to the accompanying
drawings.
Figure 1 is part sectional elevation of a valve constructed in accordance with my
former patent. a. is the inlet. h. is the outlet. The closure is effected by the descent
of the valve e provided with the packing d. This packing is not necessarily of a
rectangular shape as shown in my former specification. In figure 2 I have shown a
detached view in front elevation of the part c. showing the packing d. circular in
shape Fig. 3 is a sectional elevation of another form of valve constructed according to
my invention. In lieu of the wedge shaped valve in this modification I have shown
it of a Conical shape with the packing d. surrounding the same and secured to the
said valve by a washer e. and set screw. This valve may be free to turn in order
to change the exposed portion of the packing whilst at the same time it can readily be
removed and replaced by a new one the application of a conical packing is also shown
as applied to a hollow plug valve as shown in the example at figure 4. The packing
on this valve can be detached in a similar manner to the foregoing.
In Fig. 5 I have shown a double wedge valve in which toggle arms g are employed.
to effect greater pressure on the valve face. Fig. 6 shows a modification of this form
of valve but in which I employ a spring which immediately the valve d is released
will give according to the volume of liquid that has to pass and to automatically close
to such a position as to receive the necessary pressure.
Although I have shown my improvements as applied to ordinary cocks I would have
it understood that the same may be applied to every description of valve.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1st. In a ball or other cock or valve a sliding wedge or conically shaped valve
operated by a screw, lever, or cam, for effecting a perfect closure of the parts
substantially in the manner as described and shown in the accompanying drawings.
2nd. An angular faced valve with the back thereof tapered in order to further assist
in effecting a tight joint in the manner described and shown in the accompanying
drawings.
3rd. The method and means of securing the packing in conical seating by means of
a screw and washer substantially as shown and described in Fig. 3.
4th. The hollow conical valve with an opening communicating with the inlet such
valve being provided or not with suitable packing other than the material of which it
is made as herein set forth.
5th. In wedge valves having a flat face providing the same with a packing such
packing being circular in shape and held in a corresponding recess in the valve
substantially in the manner herein set forth with reference to the accompanying
drawings.
6th. The employment of toggle levers for exerting greater pressure on the valve
face all in the manner and for the purposes herein set forth.
