This invention relates to'certain new and use

instrument, and has more particular reference to
a device which is expressly adapted to produce
intermittently projected air streams or jets,
ranging from light puifs to vigorous rapid blasts,

lid, and opposing same to the air chamber which
is provided in the cushioned body, and making
