in the Parish of Christ Church, in the County of Surrey, Sanitary
ADAMER
PROVISIONAL SPECIFICATION left by the said John Beck at the Office of
the Commissioners of Patents, with his Petition, on the 30th October
1860.
I, JOHN BECK, of No. 10, Issabella Street, Broad Wall, in the Parish of Christ
Church, in the County of Surrey, Sanitary Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN STOP VALVES FOR WATER,
STEAM, OR OTHER FLUIDS," to be as follows, & consists in a novel method of con-
structing the lifting spindle of the valve & attachments in such a manner as
to prevent the possibility of its sticking or setting fast, a circumstance which
often occurs in the ordinary screw spindle valve; also in placing the valve &
spindle with its seat at an oblique angle to the direction of the pipe through
which the water, steam, or other fluids are intended to pass, by which means
the flow of the stream will be less impeded than it is in passing through the
usual valves set at right angles to the direction of the pipes through which the
stream or current has to pass.

by the said John Beck in the Great Seal Patent Office on the 30th April

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BECK, of No. 10, Issabella Street, Broad Wall, in the Parish of Christ Church,
in the County of Surrey, Sanitory Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of October, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
lid, for Herself, Her heirs and successors, give and grant unto me, the said
John Beck, Her special licence that I, the said John Beck, my executors,
administrators, and assigns, or such others as I, the said John Beck, my
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN STOP VALVES
FOR WATER, STEAM, OR OTHER FLUIDS," upon the condition (amongst others)
that I, the said John Beck, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Beck, do hereby declare the nature
of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
and accompanying Drawings, that is to say:-
My Invention of improvements in stop valves refers to the kind known as
the screw valve, but instead of using a close nut as in the usual method I use
a part of a nut only (say one-fourth, or in cases where great pressure is
required I use two parts of a nut on opposite sides of the spindle. The object
and advantage of thus using a part or parts only of a nut consists in its being
open so that no dirt or other substances can accumulate between the threads
of a screw and part or parts of a nut, a circumstance of sticking fast which
often happens with ordinary screw nuts, when they are allowed to stand for a
time without being used.
In the accompanying Drawing, Fig. 1 represents a vertical section of a

page_text: valve, box, screw, and part of a nut. A, the shell or box; B, the screw
spindle passing through a stuffing box with a handle or hand wheel at top; C,
the part of a nut which is fixed to a piece projecting from the lower side of the
cover to the inside of the shell or in any other manner that may be found most
convenient; D is the valve loosely attached to the spindle so as to rise and
fall with it. This valve may be either of the flat surface kind or of the conical
construction as may be found best adapted to the object in view; d, d, is the
valve seat formed either in the shell or made separately and fixed in the shell.
The nut space in the shell is kept clear of dirt by the disc a, a, fixed in the
shell which also serves to guide the valve spindle and to keep it in its central
position.
Fig. 2 shews a transverse section of the valve box or shell. B, the spindle;
C, the part of a nut. Fig. 3, a side view of the nut; and Fig. 4, a front view
of the same.
Fig. 5 shews the application of this Invention to an oblique valve, wherein
the flow of the fluid is in a straight line or without a dip or bend.
Fig. 6 represents a construction of a valve with a screw spindle, having a
lever and a float attached suitable for the discharge of fluids. II is the outlet
or discharging pipe; I, the valve orifice; J, the valve; K, the spindle; k, a
thread or part of a thread of a screw on the spindle, beneath which there is a
short part of a nut on the plate. It will be apparent that as the float L is
raised by an increase of the height of fluid by which it is surrounded it will
cause the spindle to turn in the bearings m and n, the part of a nut will cause
it to advance and force the valve towards the face thereby causing a dimi-
nution of the flow and finally "shutting off."
I do not confine myself to any general construction of these valves or
form of details except that of using a part or parts of a nut as before
described.
In witness whereof, I, the said John Beck, have hereunto set my hand
and seal, this Thirtieth day of April, in the year of our Lord One
thousand eight hundred and sixty-one.
