This invention relates to amusement devices
and games, and more particularly to an improve
ment in bases of the type used in the game of
baseball.
.
An object of my invention is to provide a base
suitable for use as a station marker in baseball
and other games and so constructed as to offer
advantages of superiority in respect of economy,
appearance and safety as compared with more
conventional bases of the same general type.
A more detailed object of the present invention
is to Áprovide a baseball base which, instead of
being in the form of a cushion stuffed with pad

The-bases now conventionally used as station
markers in the game of baseball are construct
ed according to quite exacting specifications in
respect of shape, size, and weight, and even more
particularly in respect of the exact location of
the base with relation to the base lines of the
ding material and having a fabric cover, com

This cover 3l is fashioned to provide a top por

In order to cause the base to have an exterior
