However, the cells located within the conical end
portions II have frusto-conical outer walls, so as »
to ?t snugly against the inside walls of said end
portions II. It will be clear that the described
buoy may be subjected to considerable abuse and
may be pierced at a number of points, without 10
losing more than a small fraction of its buoyancy.
Buoys are often used on nets or lines surrounding
bathing areas and when so used, are quite con

Referring particularly to the drawing, there is
shown a buoy which is generally similar to the
buoy disclosed in the aforesaid Patent No.

The hollow cell of Fig. 3 is preferably made of
some light, non-rusting metal such as copper,
duralumin, aluminum, thin steel plate (tin, chro
mium, etc.) or the like.
Instead of a metal, some

to provide a hard, tough, durable, waterproof pro

Fig. 4 may be made of vulcanized rubber, that is,
through the rings I3 and also through loops l5
which are welded or otherwise secured to the sides
of the buoy. The rope l4 preferably passes
around the entire length of the buoy on each side
thereof and provides a convenient means which
may be grasped by a person swimming in the
water.
While the described buoy may be hollow, this
is a disadvantageous construction if the buoy
should be pierced or have its walls broken, because
even a small hole will cause the buoy to be ?ood
employed.

of high grade rubber (similar to the inner tube of
a bicycle) may be employed.

named, may be employed in making the buoys 40
