Cleansing Ships' Bottoms." I apply to my said apparatus externally an

which is attached wooden or metal rollers or cylinders set upon a series of
pads or paddings of yielding material. The rollers or cylinders should
be of suitable dimensions and moveable to admit of proper adjustment. By

the sides and bottom of my said patented apparatus and perfect adhesion
between the same and the surface of the ship's hull to be acted upon is
secured.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Frederick M°Killop in the Great Seal Patent Office on
the 12th June 1866.

page_text: for an Invention for "Improvements in Cleansing Ships' Bottoms." I apply
to my said patented apparatus externally an additional belt or belts so con-
structed as to be flexible or jointed, and made of rope, wood, or other suitable
material. To the belt or belts, and as part thereof, I attach or apply wooden
or metal rollers or cylinders set upon a series of pads or paddings of yielding
material; the rollers or cylinders should be of suitable dimensions and
moveable to admit of proper adjustment, and I prefer the use of cylinders
with a piston worked by hydraulic power or pressure, as by that means the
edges of my said apparatus can be made to press and close upon or fit into
the various parts of the ship or body acted upon, and any inequalities in the
surface or lines thereof. By hauling upon the belt or
and properly adjusted greater pressure is obtained upon the sides and bottom
of my said patented apparatus and a perfect fitting or adhesion between
the same and the surface of the ship or other body to be acted upon is
secured.
belts when in position
Having now described the object and nature of my Invention, and the
manner in which the same is to be effected, I hereby declare that I claim
as the Invention intended to be secured by the said Letters Patent the belt as
above described, and the use and application for the purposes of my said
Invention of hydraulic cylinders attached or applied to such belt in manner
above mentioned.
In witness whereof, I, the said Henry Frederick M'Killop, have here-
unto set my hand and seal, this Twelfth day of June One thousand
eight hundred and sixty-six.
Witness,
