PROVISIONAL SPECIFICATION.
A New or Improved Instrument for Gauging or Indicating the
Contents of Fermenting or other Tuns or Vessels.
1 EDWIN JAMES NEALE of the Dolphin Brewery, Poole in the County of Dorset,
Brewer do hereby declare the nature of this invention to be as follows :—
The Invention relates to an instrument for ascertaining the contents of fermenting
or other tuns or vessels and whereby the exact quantity of such contents can be readily
ascertained at any moment.
For this purpose I employ a vertical tube or cylinder of brass or other suitable
metal furnished with an inner tube or lining of glass and I close the ends of this tube
or cylinder by means of screw caps which are either coated with vitreous material
upon their inner surface or compress glass or other discs upon the ends of the tube or
cylinder suitable packing rings or washers being interposed between the parts.
The interior of the tube or cylinder is connected with the tun or vessel above and
below the level of the beer therein by means of short ways or conduits also lined with
glass so that no part of the exterior metal case is exposed to the beer.
Or the upper way or connection may be dispensed with and the upper cap may be
formed with an air way or opening therein in lieu thereof.
.
A long slot is formed in the metal case or tube through which the level of the liquid
standing in the glass tube or lining may be seen and upon the metal tube at one side
of such slot is marked a scale of inches divided for example into tenths each tenth
representing 3.6 gallons of liquid in the tun or vessel and each inch representing
36 gallons or one barrel so that the contents of the tun or vessel can be read off at a
glance.
A tap or cock is provided at the front of the tube or cylinder by means of which
samples may be drawn off from time to time without fob.

COMPLETE SPECIFICATION
A New or Improved Instrument for Gauging or Indicating the
Contents of Fermenting or other Tuns or Vessels.
1, EDWIN JAMES NEALE of the Dolphin Brewery Poole in the County of Dorset
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:
The Invention relates to an instrument for ascertaining the contents of fermenting
or other tuns or vessels and whereby the exact quantity of such contents can be readily
ascertained at any moment.
For this purpose I employ a vertical tube or cylinder of brass or other suitable
metal furnished with an inner tube or lining of glass and I close the ends of this tube
or cylinder by means of screw-caps which are either coated with vitreous material
upon their inner surface or compress glass or other discs upon the ends of the tube or
cylinder suitable packing rings or washers being interposed between the parts.
The interior of the tube or cylinder is connected with the tun or vessel below the
level of the beer therein by means of a short way or conduit also lined with glass so
that no part of the exterior metal case is exposel to the beer thereby avoiding any
galvanic action on the fluid.

page_text: tenths representing 36 gallons of liquid in the tun or vessel and each inch representing
36 gallons or one barrel so that the contents. of the tun or vessel can be read off at a
glance.
A tap or cock is provided at the side or front of the tube or cylinder by means of
which samples may be drawn off from time to time without head.
And in order that the said Inve: tion may be more clearly understood and readily
carried into effect I will proceed, aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of an instrument constructed according to my invention
and showing such instrument attached to a fermenting tun or vessel.
Figure 2 is a vertical transverse section thereof and
Figure 3 is a horizontal section thereof taken on the line 1-1 of Figure 1.
In the several figures like parts are indicated by similar letters of reference.
a represents a vertical tube or cylinder of brass or other suitable metal which is
furnished with an inner tube or lining of glass, a filling of indiarubber or other
suitable cement preferably being interposed between the parts, and e represents the
wall of the fermenting tun or vessel.
The ends of the metal tube or cylinder a are closed by means of screw caps a¹ which
may be coated upon their inner surface with vitreous material as indicated at the
upper part of Figure 2 in order to complete the incorrodible lining of the tube or
cylinder a.
This construction facilitates the cleansing of the instrument as by unscrewing the
caps a¹ a brush may be readily passed into or through the glass tube 6 whilst the
instrument is in position.
upon
Or according to the modified construction represented at the lower end of Figure 2
a disc b¹ of glass, vulcanite, or other suitable material is compressed by the
cap a
a packing ring * of indiarubber or other suitable material interposed between the
end of the glass tube b and the disc in order to complete the incorrodible lining of
the tube or cylinder a.
The interior of the tube or cylinder a is connected with the tun or vessel c below
the level of the beer therein by means of a short way or conduit a² also fitted with a
glass tube or lining 2 and a tight joint is made between the glass tubes 6 and
between the tubes a and b by means of a filling or packing of cement and thus no
part of the metal tube or cylinder a or of the conduit a is exposed to the beer.
The conduit a is threaded to screw into a hole formed in the tun or vessel c and it
is furnished with a flange a³ which fits against the outside of the wall c of the tun or
vessel and is there secured by screws a ring of packing being interposed between the
parts whilst at the upper end thereof the instrument is provided with a stud or offset a²*
furnished with a flange a³* which is secured to the tun c by screws, and the instrument
is thus firmly fixed in position.
The upper cap or cover a¹ is formed with an air way or opening a* therein in order
to allow of the escape and admission of air to the instrument.
A long slot a' is formed in the metal tube or cylinder a through which the level of
the liquid standing in the glass tube or lining & can be seen and upon the metal
tube a at one side of such slot at is marked and figured so as to read downwards a
scale divided for example into inches ranging from 0-20 and into tenths, each tenth
representing 3.6 gallons of liquid absent from the tun or vessel c and each inch
representing 36 gallons or one barrel and upon the metal tube or cylinder a at the
other side of the slot at the scale is figured in the reverse order so as to read upwards

page_text: each inch representing a barrel of liquid contained within the tun or vessel c so that
the contents of the tun or vessel c can be read off at a glance.
It will, however be evident that the scale may be otherwise divided according to the
size of the tun or vessel.
A tap or cock e is provided at the side or front of the tube or cylinder a by means
of which clear samples without head may be drawn off from time to time and the
entrance to the tap or cock e is lined with a short glass tube 63 cemented in position
in a similar manner to that described with respect to the tube b².
By these means I am enabled accurately to gauge the contents of the tun or vessel
at any moment without the necessity for the employment of dipping rods, and
notwithstanding any head that may be upon the beer.
In my provisional specification I described two methods of providing an air way at
the upper part of the instrument, but I find in practice that the alternative method of
forming such air-way in the upper cap is the preferable one and I have therefore
adopted the same for the purposes of this description.
Although I have described my invention in connection with a brewing tun or vat I
would have it understood that it may be usefully employed in connection with other
vessels where it is desirable to gauge and sample the contents from time to time.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. An instrument for gauging or indicating the contents of fermenting or other
tuns or vessels consisting of a tube or cylinder in which any contained liquid may be
seen at its lower end connected with the contents of the tun or vessel by a way or
conduit and at its upper end provided with an air opening above the level of such
contents and with a sampling tap at some convenient point, and having upon its side
a scale divided to represent given quantities substantially as herein shown and
described.
2. An instrument for gauging or indicating the contents of fermenting or other
tuns or vessels consisting of a tube or cylinder having its ends closed by removeable
caps and provided with a glass lining, and at its lower end connected with the contents
of the tun or vessel by a glass lined way or conduit and at its upper end provided with
an air opening above the level of such contents and with a sampling tap at some convenient
point, such tube or cylinder being formed with a long slot and in the front or side
thereof ordered by a scale divided to represent given quantities substantially as herein
shewn and described.
