the hinge to secure the other side of the bag when in place. The upper or
lower side of the float may be covered with wire gauze or other suitable
material.

the nature of my said Invention, and in what manner the same is to be

ing statement thereof, reference being had to the Drawings hereunto annexed,
that is to say:→
My Invention consists in attaching a float to the bags used for containing
coffee, tea, or other material in pots, in which an infusion or extract is to be
made, so that the bag is always suspended from about the level of the surface of
the liquid in the pot. In carrying out my Invention I take a tube or float of
annular or other form, and I binge to its lower side a bag of wire gauze or other
suitable material; the float bas a catch diametrically opposite the hinge to
secure the other side of the bag when in place. The upper or lower side of
the float may be covered with wire gauze or other suitable material.

tical section, and Figure 3 a top view or plan of a float bag made in the
manner herein-before described. a is a bag of wire gauze, or it may be
made of perforated metal or other suitable material. 6 is a tube or hollow
float of annular form; the bag a and float bare hinged together at the point e,
and the float 6 is provided with a hasp or catch d to take on to a corresponding
catch on the bag a. e is a piece of perforated metal or other suitable material
to cover the central opening of the float b. The tea or other material is
placed in the bag a, the float b which forms a lid or cover to the bag is then
fastened down by the catch d, and the float bag is put into the tea pot or
other pot. When the water is poured into the pot the float causes the bag
to float in the water, so that the tea instead of lying at the bottom of the pot
and becoming as it were sodden is suspended in the midst of the water. fis
a handle or loop to facilitate the introduction and withdrawal of the float bag.
Figures 4 and 5 represent in elevation and vertical section respectively a
modified construction of the float bag, in which the float b is in the form of a
bollow chamber extending over the whole area of the top of the bag a, instead
of being annular as shewn in Figures 1, 2, and 3. Any other convenient
form of float may be adopted.
Figures 4 and. 5 is of
perforated metal.

And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my "Improve-
ments in Bags for Coffee and other such like Pots," attaching a float to the
bags substantially as and for the purpose herein-before described and repre-
sented in the accompanying Drawings.
