FREDERICK MACFIE MAYNARD, 12, The Polygon, Southampton, England, Brewer,
do hereby declare the nature of this invention to be as follows:-
.
A valve with index plate and pointer and the necessary inlet and outlet pipes with
a receiver to catch the waste cooling water when used with cooling apparatus. The
valve itself consists of three parts viz.: 1. The outer jacket or shell with the inlet and
outlet pipe connections and the dial affixed. 2. The inner jacket or shell-and 3. The
plug.
1: The outer jacket or shell, which with the inner jacket or shell and two vertical
divisions between the two, forms two hollow chambers which for convenience may be
called the inlet and outlet chambers, has on one side near the bottom the inlet for
steam or water or other liquid into the inlet chamber; on the other side, near the
top is the outlet for the steam or water or other liquid from the outlet chamber.
2.: The inner jacket or shell has a line of perforations extending to about ths of
its circumference a short distance from the top and facing the inlet chamber allowing
a flow of steam or liquid through this inner shell; at the bottom of its opposite
side and opening into the outlet chamber is a slot allowing the steam or liquid to flow
on its course.
3: The plug which is hollow and which fits the inner shell (being held in its
position by either a gland nut and packing or screwed spindle at base and nut) has in
part of its diameter, near the top and on a line with the perforations in the inner shell,
a sawn slot, which, when turned so as to be behind the said perforations, allows the
steam or liquid to pass from the inlet chamber through the perforations in the inner
shell at a speed consistent with the number of perforations opened by the position of
the slotted plug. The plug which is open at its lower end is shorter than the inner
shell in which it moves so that the steam or liquids as they enter the body of the plug,
through the slot at the back of the perforations in the inner shell, flow down and out
at the end through the opening, previously mentioned, in the inner shell, into the
outlet chamber and from there into the outlet pipe.
Fixed on to the outer case or shell is the semicircular dial plate, the lever or key,
which is used for turning the plug on or off, carries at its end opposite to the handle
a pointer which shows the number of perforations open, on the dial. The inlet and
outlet chambers are closed at their top end by means of a cap which screws on to the
projecting edge of the outer shell above the dial plate.

An Improved Valve and Fittings for the Better Regulation of the
Flow of Steam or Liquids for Various Purposes, Especially
Designed for use with Brewers' and Distillers' Attemperators
and the like.
I, FREDERICK MAOFIE MAYNARD, formerly of 12 The Polygon, Southampton, in
the county of Hants, and now of 12 Hamilton Terrace, Southampton, aforesaid, Brewer,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention consists in a valve or cock and fittings for the better regulation of

page_text: he flow of steam or liquids for various purposes and is especially adapted for use in
connection with brewers" and distillers' attemperators and the like.
The valve proper consists of three main parts which may be distinguished by the
terms of outer and inner shells and the hollow, plug.
These parts are arranged concentric with each other and an annular space is
provided between the wall of the valve casing or outer shell and the exterior of the
inner shell.
By partitions extending from towards the top to the bottom of the casing
the annular space is divided into two chambers one of which may, conveniently, be
termed the inlet chamber, and the other the outlet chamber.
The inlet chamber is that by which liquid or steam enters the cock, and the outlet
chamber is that by which it is conducted away from the cock. Towards the top of
the inner shell and facing the inlet is a series of orifices arranged in a horizontal row.
In the hollow plug is an aperture situated in the same horizontal plane as the orifices
in the inner shell.
.
This aperture extends throughout a part only of the plug, so that by turning the
latter communication between the inlet chamber and the plug by way of the orifices in
the inner shell is governed.
By preference, the axis of the inlet throat is at a different level to that of the outlet
throat, and the throats are not directly opposite one another.
The central hollow plug, which is open below, does not extend down to the inside
of the bottom of the inner shell. Liquid or steam delivered into the plug from the
inlet chamber passes out at the bottom of the plug and is discharged into the outlet
chamber through an aperture provided at the bottom of the inner shell.
The quantity or volume of steam or liquid passing through the valve is regulated
by the number of orifices in the inner shell freed from obstruction by turning
the plug.
By a graduated index plate and a pointer provided on the handle by which the
plug is turned the number of orifices unobstructed by the plug is indicated.
Referring to the accompanying drawings, Fig. 1 represents a vertical section on
the line x, x, Fig. 2, of my improved valve or cock.
Fig. 2 is a section on the line y y, Fig. 1, and Fig. 3 is a plan.
Surrounded by an outer casing a is an inner shell b which towards the top is
provided with a row of orifices c arranged in the same horizontal plane.
Between the outer and inner shells a and b intervenes an annular space d divided
by wings or partitions d' into two compartments, one of which, e, constitutes an inlet
chamber and communicates with the inlet throat f, the other, e¹, being an outlet
chamber in communication with the outlet throat f¹.
The plug h of the valve is hollow and is open at the bottom. It does not extend
down to the inside of the bottom of the shell b. Towards the top of the plug and
extending partially round it is an elongated aperture i situated in the same horizontal
plane as the orifices c in the inner shell b.
A like aperture k is provided towards the bottom of the inner shell 6 at that side
thereof which faces the outlet throat f¹.
The plug, which is surrounded at the top by a gland 1, is surmounted by a handle m
terminating at one end in a pointer n working over the face of a graduated
plate n'.
When it is desired to permit steam or liquid to pass through the cock, the plug his
turned so as to present the aperture i to one or more of the orifices caccording to the
quantity of steam or liquid to be admitted.
The position of the pointer n in relation to the graduations on the plate n³ indicates
the number of orifices open.
The steam or liquid enters the plug through the unobstructed orifices and
descending to the bottom of the plug passes out by the aperture k into the outlet
chamber and the outlet throat f The outlet and inlet throats being arranged at
different levels and not being opposite to one another the force of the entering current
of water or steam is consequently broken before passing to an attemperator or like
vessel with which the outlet is in communication.

page_text: Under a modification the inner shell b, instead of being made separate from, is cast
in one piece with the outer casing a.
The plug instead of being carried down through the outer casing and secured below
by a nut may be secured by a gland at the top.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. An improved valve or cock for steam or liquids (especially designed for use
with brewers' and distillers' attemperators and the like) consisting of an outer casing
such as a, an inner perforated shell such as b, with aperture k, between which inner
shell and outer casing intervenes an annular space divided into inlet and outlet
chambers by wings or partitions such as d', and a hollow open-ended plug such as h
with aperture i, all arranged and operating to control the volume and force of steam
or liquid delivered through the valve or cock, substantially as herein before described
with reference to the accompanying drawing.
2. The combination with a regulating valve, for use with brewers' and distillers'
attemperators and the like, of a graduated indicator plate and a pointer affixed to the
central perforated plug of the valve, the graduations on the plate being, in conjunction
with the position of the pointer, an index of the number of perforations freed as the
plug is turned to admit steam or liquid through the cock or valve, substantially as set
forth.
