CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF BALL VALVES
Year: 1877

page_text: LETTERS PATENT to Joseph James Day, of No. 76, Leighton Road, Kentish
Town, in the County of Middlesex, Gas Fitter, for the Invention of "CERTAIN
IMPROVEMENTS IN THE CONSTRUCTION OF BALL VALVES."
Sealed the 23rd November 1877, and dated the 24th May 1877.
PROVISIONAL SPECIFICATION left by the said Joseph James Day at the
Office of the Commissioners of Patents on the 24th May 1877.
"
JOSEPH JAMES DAY, of No. 76, Leighton Road, Kentish Town, in the County
of Middlesex, Gas Fitter. CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF BALL
VALVES."
This Invention relates to certain arrangements whereby the flow of water is
gradually shut off or opened by the action of an eccentric or cam formed on the
end of a lever (to which an ordinary ball float is attached) on which a stud or pin
is cast on either side, and a socket formed on the other side.
The eccentric or cam works on a fluted triangular loose or drop valve, which is
made to fit the bore of the body loosely, and seats itself by means of à leather or
india-rubber washer, which is fixed on the end of the fluted triangular loose or drop
valve by means of a plain round-headed set screw which rests upon the eccentric
or cam formed at the end of the lever for either opening or shutting the valve, and
which shuts itself against the pressure of the water in the drip.
The body of the valve is cast with a boss on each side of the nozzle, and either
boss may be drilled on one side, right through into the nozzle, and followed up by
the same drill half way through the inner side of the other boss to form a loose
bearing for the pin on the side of the lever. The boss which is drilled right
through must be screwed inside to receive a milled edged screw with a male end to
meet the socket on the lever to form a bearing for the other side of the lever, and
which allows the eccentric or cam to act loosely in the drip, and prevents any
corroding or setting of the lever upon which the eccentric or cam is formed.

"
JOSEPH JAMES DAY, of No. 76, Leighton Road, Kentish Town, in the County
of Middlesex. CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF BALL VALVES."
This Invention relates to certain arrangements whereby the flow of water is
gradually shut off or opened by the action of an eccentric or cam formed on the end
of a curved lever (to which an ordinary ball float is attached), on which a stud or
pin is cast on either or both sides, and a socket may be formed in lieu of either stud
or pin on either side of the eccentric or cam which is formed on the end of the
curved lever.
The eccentric or cam works on a fluted triangular loose or drop valve, which is
made to fit the bore of the body loosely, and seats itself by means of a leather or
india-rubber washer, which is fixed on the end of the fluted triangular loose or drop
valve by means of a plain round-headed set screw which rests upon the eccentric or
cam formed at the end of the said curved. lever for either opening or shutting the
valve, and which shuts itself against the pressure of the water in the drip. The said
lever is curved from the pins, or socket and pin, sufficiently to clear the drip of the
body
The body of the valve is cast with a boss on each side of the nozzle, and either
boss may be drilled on one side, right through into the nozzle, and followed up by
the same drill half way through the inner side of the other boss to form a loose
bearing for the studs or pins, or socket and pin, on the side of the eccentric or can
formed on the end of the curved lever. The boss which is drilled right through
must be screwed inside to receive a milled edged screw with either a male or female
end to meet the socket or pin on the side of the eccentric or cam formed on the end
of the curved lever to form a bearing for the other side of the said curved lever,
and which allows the eccentric or cam to act loosely in the drip, and prevents
any corroding or setting of the curved lever upon which the eccentric or cam is
formed.
Having thus described and ascertained the nature of my said Invention, and
in what manner the same is to be performed, I would observe in conclusion that
what I consider novel and original, and therefore claim as constituting the Invention
secured to me by the said herein-before in part recited Letters Patent is, the set
screw, with either the male or female end and socket or studs, or pins, which is formed
on the eccentric or cam at the end of the said curved lever, together with the com-
bination of the other parts of the said valve or any mere modifications thereof.
In witness whereof, I, the said Joseph James Day, have, hereunto set my
hand and seal, the Third day of December, in the year of our Lord One
thousand eight hundred and seventy-seven.
