This invention relates to polishing equipment,
and more particularly to polishing equipment for
bowling balls.
A main object of the invention is to provide a
novel and improved apparatus for polishing bowl
ing balls and the like.
A further object of the invention is to provide a
new and improved bowling ball polishing machine
to provide a false bottom for the bowl-shaped re
ceptacle 20.
A bowl-shaped member 25 of similar structure
to member 20 is rigidly supported by an appro-'
priate bracket member from the under surface
of shelf 5 in vertical registry with bowl-shaped
member 20 and identical lateral bowl-shaped
members 26 are provided, said lateral members
being rigidly supported on vertical bars 27 se
