This invention relates to stagings and plat
forms and more particularly to an adjustable
staging to be used by the vario-us artisans and
workers who have to do work on vertically in
clined surfaces, such as the sides of a ship.
An object of this invention is to provide a
staging which can be adjusted to fit the inclina
tion that a surface or structure makes with the

ers who have to do work on the sides of a ship,
especially near the bow or stern. The entire stag
ing can be lashed securely to a floating base or
barge adapted to be anchored near a ship or
moored thereto, the sides of said `ship being in
clined .to the vertical, said inclination being dif
ferent for different sections of the ship.
In con
ventional stagings where the rigging or staging
is fixed, certain painters on all levels but one are
too far from the ship’s side as the fixed-staging
is moved, in its entirety, from one section to
another section of the ship. Painters who are on
platforms too far from the ship'ïs side cannot
paint accurately or comfortably, and accidents '
are likely to occur.
The description of the adjustable staging of the
present invention for use in the painting of `a
ship’s side is only one example of its use, and does
without departing from the spirit and scope'
thereof as set forth in the appended claim.
The invention described herein may be manu
factured and used by >or for .the Government of
the 'United States of America for governmental
purposes without the payment of any royalties
thereon or therefor.
What is claimed is:

a vertically .disposed supporting structure secured

structure, turn~buckles pivctally secured to said
