JOHN LE PATOUREL Merchant Les Terres Guernsey and SOLOMON HYAMS Umbrella
Maker 11 Upper St. James Street Brighton do hereby declare the nature of this
invention to be as follows:-
The Barometer consists of a glass bulb with a long tube inverted in a glass
reservoir within an inch or so from the bottom, before thus fixing them together, the
reservoir is nearly filled up with coloured water, and just as much of it as would have
filled the reservoir quite full is put in the bulb which is quickly inverted and the end
of the tube inserted into the reservoir then sealed, they are then placed on a wooden
board or frame having near the top and bottom cavities prepared to imbed the bulb
and reservoir respectively, so that the tube may lay flat on the frame, or the whole unay
be fully imbedded in the frame, and the frame so made as to take or admit a pane of
glass over the whole, printed matter on the sides of the tube included. The bulb and
reservoir are a little flattened in shape, on the left side of the tube the instructions
are printed on the board, on the right is the indicator, a wire from top to bottom with
a hand to slide up and down. The inches and tenths of inches are marked on the
tube, the water in the tube rises and falls according to the atmosphere and is most
sensitive and correct.
This Barometer may be made of different sizes, a middling size one would have a
tube 10 or 11 inches long by 1 inch diameter the bulb and reservoir would hold
respectively of a pint or thereabout, the frame would be about 18 inches long
by 3 inch wide, the reservoir has a hole on the top the exact size to admit the tube.
When the water has been put in the reservoir and tube and they are connected and
sealed, the thing is fixed on the frame, on the left the instructions are printed as on
Fitzroy's. On the right is the indicator which is a hand fitted to travel up and down
a wire the length of the tube, both ends of this wire are fixed to the frame, the hand
is made firm where desired by means of a thumb screw the rise of the water in the

page_text: tube foretells fine weather, the fall bad weather, each morning at a given hour the
hand is placed on a level with the water in the tube, and any one looking at the
Barometer during the day can see at a glance whether the water in the tube has risen
or fallen and know what weather to expect.
We claim the invention of making a Barometer without mercury, (as described
above) that will foretell the weather as truly as the most expensive, and much cheaper
than any yet out.
It is Tha Poonlo's Barometer "
Wo JOHN LE PATOUREL of Les Terres Guernsey Merchant and SOLOMON HYAME,
of 11 Upper Saint James Street, Brighton Sussex Umbrella Maker 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:
To enable our invention to be properly understood, I will proceed to fully describe
the same with aid of the accompanying drawing.
The Barometer consists of the glass tube A having a bulb B, the bottom of tube A
being inserted in a reservoir C, and sealed hermetically tight; the barometer is
secured to a suitable frame or support E, in any convenient manner, this frame E, may
be marked with any desired scale and have a pointer F, to record same; this pointer
may be held in a slot G, so that it may be moved up or down as required.
The Barometer is constructed as follows,
We first fill the reservoir C, with any suitable liquid, preferable coloured water,
then a portion of this, sufficient to half fill the length of the tube A, is poured from
the reservoir C, down tube A, into bulb B, we then quickly insert the end of tube A,
into reservoir C, about half way down and seal hermetically tight at the entrance;
by this means a certain amount of air is retained in the bulb B, which acts as an
elastic cushion on the liquid in the tube A and causes the height thereof to rise and
fall according to the changes in the atmosphere. The air in bulb B pressing on the
liquid in tube A just in proportion and according to the pressure of the atmosphere

page_text: outside. By marking the height of the water in the tube A every morning by the
pointer F will readily show variations, the rise of the water in the tube A, foretells
fine weather and the fall bad weather.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed we declare that what we
claim is
The improved Barometer constructed as herein described and illustrated in the
accompanying drawing.
