This invention relates to an apparatus for turn

It is often necessary to treat successively the
various longitudinal side surfaces of a heavy body,

We have developed an economical and highly
e?icient apparatus for turning an elongated steel
body about its longitudinal axis. The apparatus
comprises a wrench plate having an opening
through which the steel body extends when in the
operative position, the wrench plate being
adapted to selectively engage a hoist member so

plate .1 l is placed over the end of the bloom 5 sub

turn the bloom through 90° about its longitudinal
axis and position surface 1 uppermost, the hook
I4 is connected to the opening I3 which is spaced
from the corresponding ~side surface ‘I. The
chain hoist I5 is then raised by the hoist, not
shown, to rotate the bloom 5 through 90° to the
position indicated in broken lines on Figure 1.
If it is desired to rotate the bloom 5 so as to dis
