Year: 1869

page_text: LETTERS PATENT to Sam Smithson, of Heckmonḍwike, in the County
of York, Dyer, and George Senior, and John Inman, of Brighouse,
in the same County, Brass Finishers, for the Invention of "IM-
PROVEMENTS IN VALVES OR VALVE TAPS FOR REGULATING THE DISCHARGE OR
FLOW OF WATER OR OTHER FLUIDS OR GASES."
Sealed the 1st January 1870, and dated the 2nd July 1869.

page_text: NOW KNOW YE, that we, the said Sam Smithson, George Senior, and
John Inman, do hereby declare that the following Complete Specification,
under our hands and seals, fully describes and ascertains the nature
of the said Invention, and in what manner the same is to be performed,
in and by the following statement, reference being had to the accom-
panying Drawings making a part of this Specification (that is to say):-
This Invention relates to valves or valve taps for regulating the dis-
charge or flow of fluids or gases, and consists in constructing either the
valve or its seating of cork, lead, or a composition of lead and antimony,
and by preference such valves or seatings are formed in circular and
angular corrugations or rings and capable of moving to or from each
other without turning on their axes, also the spindles are formed to fit
conical glands or boxes so as to avoid packing.
In order that the Invention may be readily and fully understood, we
herein give reference to a Sheet of Drawings of valves or valve taps
constructed in accordance therewith.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation, and Fig. 2 is a section of a double valve tap.
A and B are valves differing slightly in construction, yet both having
the same characteristics of the novelty of this Invention. The face of
each valve is dished or a cavity is formed therein and then filled in with
either cork, lead, or a composition of lead and antimony, which latter we
prefer. C and D are seatings, which it will be seen are turned or faced
in angular rings so as to impinge upon the cork, lead, or composition
of the valve, and thereby form their own matrices. The spindles
E and F are screwed to fit either into or on to the valves, and are formed
with conical collars or otherwise, as respectively shewn, to fit glands or
boxes G and H, which make tight joints without the use of any kind
of packing. The spindles are capable of turning on their axes, and the
valves are prevented from turning by having wings a, b, thereon to fit
grooves formed in the shell of the tap; thus by turning the spindle by
hand wheel or otherwise the valve is moved nearer to or further from
its seating according to the direction of its being turned right or left, as
will be well understood.
Fig. 3 is a section of a single valve tap shewing that the valve A
may be faced in angular rings and the seating formed so as to be filled
up with cork, lead, or a composition, as aforesaid; also the spindle made
conical to fit the box in a different manner to those in Figs. 1 and 2.

page_text: Fig. 4 is a section of another single tap shewing that the faces of
the valve and its seating may be at an angle to the line of movement of
the valve spindle, so as to obtain a straight waterway or clear course for
the passage of fluids or gases.
Having thus described the nature of our said Invention, and shewn
by the Drawings how the same is to be performed or carried into practical®
effect, we would have it understood that we do not confine ourselves
to the precise details in the construction of these valve taps, as various
modifications may be made therein without departing from the main
feature of the Invention; but what we do claim as our Invention is,--
Firstly. The application and use of cork, lead, or a composition of
lead and antimony for either the valve or the seating of such taps.
Secondly. The method of making one face, whether valve or seating,
corrugated or in angular rings so as to impinge upon the cork, lead, or
composition of the other face.
Thirdly. In making the spindles of such valves conical to fit in a gland
or box, and thereby to avoid packing.
Fourthly. The construction, combination, and arrangement of valve
taps in manner substantially as herein described and shewn by the
Drawings.
In witness whereof, we, the said Sam Smithson, George Senior,
and John Inman, have hereunto set our hands and seals, this
Thirtieth day of June, in the year of our Lord One thousand
eight hundred and sixty-nine.
