The present invention relates to apparatus for auto
matically setting _pins on a bowling alley.
Until very recently there were no automatic pin set
ters in' use; and bowling pins were set either by hand
or by so-called semi~automatic pin spotters. There are,
therefore, a great number `of bowling alleys throughout
the country that were built before any automatic pin
Setters were on the market.

or lift in a pit at the rear end 'of the alley iioor. Some
or all of the pins, which have been knocked down by the
ball, may drop into this lift or elevator also, although
most of them will fall into the pin elevator which is
disposed in the pit also but which is in front of and
under the ball lift.
