IMPROVEMENTS IN BALL COCKS OR VALVES.”
Year: 1881

page_text: LETTERS PATENT to Samuel Owen, of Fann Street, Aldersgate Street, in the
County of Middlesex, for an Invention of "IMPROVEMENTS IN BALL COCKS
OR VALVES.”
PROVISIONAL SPECIFICATION left by the said Samuel Owen at the Office
of the Commissioners of Patents on the 16th June 1881.
SAMUEL OWEN, of Fann Street, Aldersgate Street, in the County of Middlesox.
"IMPROVEMENTS IN BALL COCKS OR VALVES."
The Invention has for its object improvements in ball cocks or valves whereby
the same are rendered efficient in action, easy of repair, and not liable to set or
stick fast, whilst they are of simple construction and are cheap to produce.
For this purpose I form the outlet end of the body of the tap or valve with a
socket or recess to receive a packing or seating of india rubber or other suitable
material, preferring to employ therefor a thick fabric of hemp or flax punched or
cut to the required size and shape.
Around the exterior of the outlet end of the body is formed a screw to fit a
female thread formed within a ring or cover used to keep the packing or seating
in position, and to carry the axis of motion of the strig or ball lever.
The plug of the valve is formed conical to fit a similarly shaped hole in the
packing or seating, and it is also formed with a slotted projection through which
the strig or ball lever is passed, by which means the latter as it falls is caused to
pull the plug or valve away from its seat and thereby to prevent the sticking
thereof, whilst in rising it presses the plug or valve to its scat.
I also, according to my Invention, form the two parts of the ball of such shapo
and size as to place the seam or junction thereof at a position above the line of
Hoatation of tho ball.

an Order of the Lord Chancellor, filed by the said Samuel Owen in the Great
Seal Patent Office on the 21st December 1881.

IMPROVEMENTS IN BALL COCKS OR VALVES."
The Invention has for its object "Improvements in Ball Cocks or Valves,"
whereby the same are rendered efficient in action, easy of repair, and not liable to
set or stick fast, whilst they are of simple construction and are cheap to
produce.
For this purpose I form the outlet end of the body of the tap or valve with a
socket or recess to receive a packing or seating of india rubber or other suitablo
material, preferring to employ therefor a thick fabric of hemp or flax punched or
cut to the required size or shape. Around the exterior of the outlet end of the
body is formed a screw to fit a female thread formed within a ring or cover used
to keep the packing or seating in position to carry the axis of motion of the strig
or ball lover.
The plug of the valve is formed conical to fit a similarly shaped holed in the
packing or seating, and it is also formed with a slotted projection through which
the strig or ball lever is passed, by which means the latter as it falls is caused to
pull the plug or valve away from its seat and thereby to prevent the sticking
thereof, whilst in rising it presses the plug or valve to its seat.
I also, according to my Invention, form the two parts of the ball of such shape
and size as to place the scam or junction thereof at a position above the line of
flotation of the ball.
In witness whereof, I, the said Samuel Owen, have hereunto set my hand
and seal, this 21st day of December, in the year of our Lord One thousand
cight hundred and eighty one.
SAMUEL OWEN. (L.S.)
