Improvements in the manufacture of Valve Cocks.
Year: 1886

page_text: I, ARTHUR HERBERT PINNOCK, of "Beechwood," Newport, Isle of Wight,
Merchant, do hereby declare the nature of this invention to be as follows:-
This Invention relates to improvements in valve cocks for water pipes. The
valve consists of a cylindrical casing formed of cast malleable iron which is gal-
vanized as a protection against corrosion. The casing is formed with a diminishing
end which is threaded to screw into the main, and the seating of the valve is formed
a slight distance above the reduced portion of the casing. Above this is a lateral
orifice which forms the outlet. The spindle of the valve passes through a brass
cap screwed on to the top of the cylinder or casing.
Valves constructed according to my Invention will be found cheaper and more
durable than those in ordinary use.

Improvements in the manufacture of Valve Cocks.
I ARTHUR HERBERT PINNOCK, of "Beechwood," Newport, Isle of Wight,
Merchant, do hereby declare the nature of this Invention, and in what manner
0 the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This Invention relates to improvements in
s
screw down" valves for union or
supply purposes, and consists in dispensing in some cases with the stuffing boxes

page_text: and other accessory parts which are now used when effecting a junction between
the main and a branch pipe.
In order to make my Invention more fully understood I have hereto annexed a
sheet of drawings illustrative thereof.
Figure 1 represents my improved valve applied to a T pipe or union.
In this case the union is cast with an outlet A, valve seating A¹, valve casing
B covered by the cap B¹ provided with a stuffing box B. The valve is composed
of a brass or other metal washer C attached to the spindle C¹. This is covered on
each side by leather washers C, the washers being secured to the spindle by
screw C³.
Figure 2 shews the application of my Invention to an elbow union, in which case
the pressure is supposed to be exerted on the underside of the valve thereby enabling
me to dispense with the screw C³ and employ the ordinary loose valve. In this form
of valve I can dispense with the stuffing box, as by screwing the plug D up against
the washer B, a tight joint is formed.
Figure 3 represents my Invention as applied to an ordinary supply pipe. It is
here screwed onto the end of the pipe and the casing is provided with an outlet E.
The same letters of reference are applicable to similar parts in each figure.
It will be observed that I dispense with the usual sockets in connecting my valve
with the main or supply pipe and thus reduce the cost and trouble of effecting such
connection.
The valve-casing may be made of any material, but I find cast galvanized iron
cheaper and as durable as brass.
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:
1. A cock or valve so constructed as to dispense with any stuffing box, substan-
tially as specified.
2. The method of applying my Invention to unions and supply pipes, substan-
tially as herein shewn and described.
