IMPROVEMENTS IN HOT WATER VALVES
Year: 1877

page_text: LETTERS PATENT to William Byram, Employé of Messrs. Walton and Brear, of
Bradford, in the County of York, Plumbers and Gas Fitters, for the Invention
of IMPROVEMENTS IN HOT WATER VALVES."
Sealed the 16th November 1877, and dated the 17th May 1877.
PROVISIONAL SPECIFICATION left by the said William Byram at the Office
of the Commissioners of Patents on the 17th May 1877.
"
WILLIAM BYRAM, Employe of Messis. Walton and Brear, of Bradford, in the
County of York, Plumbers and Gas Fitters. IMPROVEMENTS IN HOT WATER
VALVES."
The object of this Invention is to procure a direct passage through the valve,
together with simplicity of construction.
I construct the shell or casing of the valve with the outlet and inlet passages
directly opposite each other, and around the outlet passage I form the valve seating.
The valve consists of a piece of metal faced with india-rubber or other suitable
substance, which is connected to and pressed on to the seating by a finger attached
to the valve spindle, which enters the casing though a stuffing box at right angles
to the inlet and outlet, the said finger acting on the centre of the valve only so as
to insure perfect fitting on the scat. By turning tlie valve spindle the valve is
raised entirely from the scat and clear of the passage, so as to offer no obstruction
to the flow of water.
i
By my improvements screw spindles are dispensed with, and a perfectly free
passage obtained.
The casing may be made in two parts, attached together by screws or bolts, to
afford every facility for cleaning or replacing the valve.

County of York, Plumbers and Gas Fitters. IMPROVEMENTS IN HOT WATER
VALVES."
The object of this Invention is to procure a direct passage through the valve,
together with simplicity of construction.
I construct the shell or casing of the valve with the outlet and inlet passages
directly opposite each other, and around the outlet passage I form the valve scating.
The valve consists of a piece of metal faced with india-rubber or other suitable
substance, which is connected to and pressed on to the seating by a finger attached
to the valve spindle, which enters the casing through a stuffing box at right angles
to the inlet and outlet, the said finger acting on the centre of the valve only so as
to ensure perfect fitting on the scat. By turning the valve spindle the valve is
raised entirely from the seat and clear of the passage, so as to offer no obstruction
to the flow of water.
By my improvements screw spindles are dispensed with, and a perfectly free
passage obtained. The casing may be made in two parts, attached together by
screws or bolts, to afford every facility for cleaning or replacing the valve.
In order that my Invention may be more fully understood, I herein give reference
to the accompanying Sheet of Drawings illustrative thereof.
Fig. 2 is side elevation of valve casing; Fig. 3 is end view thereof; Fig. 5, plan
view.
Fig. 1, section through centre of spindle.
Fig. 4, section, shewing valve closed; and Fig. 6, section, shewing valve open.
A is the valve casing or shell, having inlet passage a and outlet passage b; B is
the valve seating formed around the outlet passage; C is the valve, which is of
metal, faced with india-rubber or other suitable substance e. This valve is attached
loosely to the spindle D by the hinges d, and is pressed on to the seating by the
finger E, which is attached firmly to the valve spindle D. The end of this finger
acts within a small socket F at the back of the valve. The casing is made in two
parts, connected together by screws or bolts e.
Having now described the nature and particulars of my Invention, I would have
it understood that I do not confine myself to the exact details herein shewn and
described, but what I do claim as my Invention and consider to be new is, the
construction of hot water valves, substantially as herein shewn and described.
In witness whereof, I, the said William Byram, have hereunto set my hand
and seal, this 10th day of November, in the year of our Lord One thousand
eight hundred and seventy-seven.
Signed, sealed, and delivered
in the presence of
THOMAS WALTON,
JOSEPH RICHARDSON.
