PROVISIONAL SPECIFICATION.
Improvements in Hauling Goods and Cargo when the Pull is Past
an Angle.
I, ALFRED ERNEST MARKWICK, of Karachi, in the Province of Sind, in the
Empire of India, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in hauling goods and cargo when the pull
is past an angle, and has more particular reference to hauling cargo out from
those parts of a ship's hold which are not directly underneath the hatchway. As
this application of my invention is one which thoroughly exemplifies its nature, I
now describe such application, the special object of which is to expedite the task of
unloading, as well as to diminish the noise, and wear of tackle inseparable from the
present method,
As the hatchways are now arranged, a very large amount of friction, strain and
wear to both ship and tackle is experienced in hauling out cargo from under the
hatches, more especially from the fore and aft ends.
In carrying my invention into effect I provide rollers which may be grooved or
parallel. These rollers are of any suitable shape and length. They are supported
or journalled in any convenient way along and at or near the under bottom side of
the hatches close to the coamings.
This position may be varied provided that they will take the hauling rope or
chain. End flanges may be provided to prevent the hauling rope slipping off.
I prefer wire rope to chain, grooving the rollers accordingly.
•
For the purpose of preventing the pressure of the taut hauling rope as it passes
over the rollers from straining them or their bearings or journals, there are pro-
vided suitable supports which I prefer to take the form of anti-friction rollers,
having independent bearings and adapted to press down upon the top sides of the
rollers about which suitable smooth peripheries are prepared.

COMPLETE SPECIFICATION.
Improvements in Hauling Goods and Cargo when the Pull is Past
an Angle.
1, ALFRED ERNEST MARKWICK, of Karachi, in the Province of Sind, in the
Empire of India, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to improvements in hauling goods and cargo when the pull
is past an angle, and has more particular reference to hauling cargo out from those
parts of a ship's hold which are not directly underneath the hatchway. As this
application of my invention is one which thoroughly exemplifies its nature, I now
describe such application the special object of which is to expedite the task of
unloading, as well as to diminish the noise and wear of tackle inseparable from the
present method.
As the hatchways are now arranged, a very large amount of friction, strain, and
wear to both ship and tackle is experienced in hauling out cargo from under the
hatches, more especially from the fore and aft ends.

page_text: In carrying my invention into effect, I provide rollers which may be grooved or
parallel. These rollers are of any suitable shape and length. They are supported
or journalled in any convenient way along and at or near the under bottom side of
the hatches close to the coamings.
This position may be varied, provided that they will take the hauling repe or
chain. End flanges may be provided to prevent the hauling rope slipping off.
I prefer wire rope to chain, grooving the rollers accordingly.
For the purpose of preventing the pressure of the taut hauling rope as it passes
over the rollers from straining them or their bearings or journals, there are pro-
vided suitable supports which I prefer in the form of anti-friction rollers having
independent bearings and adapted to press down upon the top sides of the rollers
about which suitable smooth peripheries are prepared.
The accompanying drawings illustrate the above mentioned application of my
invention.
Fig. 1 is a detail front elevation.
Fig. 2 is a detail side elevation, partly in section.
Fig. 3 is a plan, on a smaller scale, of the ladder end of a hatchway and of the
invention applied thereto.
Like parts are marked throughout the figures with the same reference letter.
a is the deck; and by the hatchway. is the ladder leading down into the hold.
d is a coaming, beam, or equivalent part of the vessel according as to whether
the invention is used fore and aft or athwartships. e, e are brackets fixed thereto,
and having bearings formed in them in which a shaft ƒ is journalled. 9, are
rollers supported axially upon the shaft f. It is these rollers which are the
operative members of my invention, inasmuch as they keep the hauling rope away
from the underside of the hatchways as it (the rope) is hauled past the angle.
They have preferably concave and equidistant annuli or grooves h, h, formed in
their peripheries to receive the hauling rope i. I prefer to use a wire rope as
illustrated to a chain inasmuch as it runs more smoothly and quietly. j, j are
flanges at the outer ends of the outer roller's. They are provided for the purpose
of preventing the hauling rope being fouled by the brackets or adjacent parts.
k, kare antifriction rollers carried at a proper height by brackets I, I so as always
i
to be in contact with the corresponding portions of the peripheries of the rollers g, g
which are of a corresponding contour. The figures illustrate the contours of the
antifriction rollers and of the corresponding portions of the rollers g as parallel
with their respective axes, but they may be respectively concave and convex.
either case the contours are preferably turned to diminish friction. These rollers
are preferably in pairs as shewn in Fig. 2 for the purpose of more thoroughly
preventing the shaft being bent.
In
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
The combination with a hatchway in deck or floor of one or more rollers
supported as hereinbefore set forth and adapted to keep the hauling rope or chain
away from the underside of the hatchway, as set forth.
