IMPROVEMENTS IN COCKS
Year: 1884

page_text: I, WILLIAM MABERLY LLEWELLIN of Bristol in the County of Gloucester and of
Glasgow in the County of Lanark, Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN COCKS" to be as follows:-
1
This Invention which has for its object improvements in cocks relates more
especially to that class of cocks used for the supply of water for domestic and other
purposes.
Under this Invention the goose neck, that is to say, the part of the pipe, through
which the water is discharged, instead of turning through a vertical or horizontal
arc as usual or actuating a ground in plug when it is desired to open or close the
cock, is with the like object moved up and down in a straight line so as to bring a
hole or opening in the side of the discharge pipe opposite the channel in the cock
communicating with the water pipe or main. The said vertically moving pipe is
closed at its lower end and works in a channel made in a faucet or barrel connected
to the water pipe or main, and at the upper and lower ends of the said faucet or
barrel the vertically moving pipe is packed water tight by means of cup leathers,
india rubber, or other equivalent packings.
The faucet or barrel may be connected to the water supply pipe by a solder or
other ordinary joint or it may have a flange at the connecting part and which is
bolted to a corresponding flange on the end of the supply pipe.
This latter part of the arrangement is also applicable to ordinary water cocks
used for the like purpose and by its employment the necessity of keeping or making
what are known as right and left barrels is dispensed with.

I, WILLIAM MABERLY LLEWELLIN of Bristol in the County of Gloucester and of
Glasgow in the County of Lanark, Engineer, do hereby declare the nature of the
said Invention for IMPROVEMENTS IN COCKS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
My said invention which has for its object improvements in cocks relates more
especially to that class of cocks used for the supply of water for domestic and other
purposes.
Under the invention as seen in vertical section at figure 1, and in elevation at
figure 2, of the drawings annexed the tube or pipe a, through which the water is
discharged, instead of turning through a vertical or horizontal arc and actuating
a ground in plug as usual, when it is desired to open or close the cock, is with the
like object moved up and down in a straight line, so as either to establish or cut off
communication between the interior of the pipe and the channel b, in the faucet d,
communicating with the water service pipe or main. Such communication is made
through holes or openings or through a hole or opening c, in the vertically moving
pipe which is closed at its lower end a³, and works in stuffing boxes and glands e,
at the upper and lower ends of the barrel h, the said boxes being packed water
tight by means of leather washers f, and metal rings g, or by cup leathers, india
rubber webbing, asbestos or other rings or equivalent packings. The glands may
be screwed into the stuffing boxes as shown or they may be jambed down by screws
and nuts and the barrel h, may be made, in one piece with the faucet d, or bolted,
'screwed or otherwise connected thereto. When a greater length of tube a, is
required the part above the barrel may be made telescopic so as to be capable of
extension, the joint being rendered water tight by a stuffing box and packing. The
part of the tube a, below the barrel may as seen at figure 1, be enclosed in a pocket
or shield i, so that when pushed down it shall not be soiled by dirty water or other
obnoxious matter contained in the sink or jawbox the said casing also shielding it
from knocks.
The faucet d, may be connected to the water supply pipe by a screw joint as
shown or by a solder, flange, or other ordinary joint.
Instead of working vertically as shown on the drawings the tube a, may work
horizontally or at any desired angle.
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
In a cock for the supply of water or liquids for domestic and other purposes a
tube open at one end and closed at the other, the closed end being encased or not

page_text: in a pocket or shield the said tube having one or more openings in its side and
working through a barrel (in which it is packed water tight) to open or close
communication with the service pipe substantially as described.
