An important object of the invention is to pro
vide an improved pile driving attachment which
is connected directly'to the outer end of the boom
and which may be'readily and easily placed in
15 position for driving piles at any angle within a
variable radius, whereby numerous piles may be'
driven without moving the entire pile driver,
which results in a great saving of time and labor.
Another object of the invention is‘ to provide a
support in connection with the attachment which

angle bars 35 are secured together and extend
downwardly between the spaced angle members
