PROVISIONAL SPECIFICATION.
Improvements in Revolving Warp-guides, Bollards, Fair-leaders, and
the like.
I, JOHN RICHARD STURDY, of 53 Eleanor Street, Grimsby, in the County of
Lincoln, Consulting Engineer, do hereby declare the nature of this invention to be
as follows:-
According to this invention I make the centre part or bush of the drum of cast
nietal, such as iron or steel for example, and adapt it to turn on a centre pin
secured in a strong baseplate in the usual way. I form the said centre part or
bush with dovetail grooves preferably parallel or nearly so, to the axis of the drum,
and I fit into these dovetail grooves suitably shaped strips or blocks of wood which
are secured end wise in the said dovetail grooves by means of screws passing through
plates forming end flanges at top and bottom of the drum. Or instead of being
fastened by screws, the ends of the strips or blocks of wood may be made to take
into suitably shaped recesses formed in the said plates or flanges.
The outer faces of the strips or blocks of wood may be shaped to a concave
curve such as is usually employed in warp-guides, bollards, fairleaders and the like,
and they may be beaded or sheathed with metal to protect them more or less
from wear and tear. The centre part of the drum is so shaped at both ends that
either end is adapted to bear on the part of the base plate or other surface upon
which the drum turns, so that when the druin gets worn at the lower part it can be
easily lifted off the centre pin, even by an unskilled person, and reversed, that is to
say turned upside down so that the worn part may be at the top, and the unworn
part brought into action at the bottom.
When the wooden strips or blocks become worn they can readily be renewed.
I also provide an oil box at the top of the centre pin and centre part or bush of
the drum provided with pipes or channels for conveying oil automatically to the
working parts, and this oil box is preferably covered over with a protecting plate
which may be secured to the upper plate or Hange of the drum or otherwise.

COMPLETE
SPECIFICATION.
Improvements in Revolving Warp-guides, Bollards, Fair-leaders, and
the like.
I, JOHN RICHARD STURDY, of 55 Eleanor Street, Grimsby, in the County of
Lincoln, Consulting Engineer, do hereby declare the nature of the said invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
According to this invention I make the centre part or bush of the drum of a

page_text: warp-guide, bollard, or fair-leader of cast metal such as iron or steel for example,
and adapt it to turn on a centre pin secured in a strong base plate in the usual way.
I form the said centre part or bush with dovetail or other suitably shaped grooves
preferably parallel or nearly so to the axis of the drum, and I fit into those grooves
suitably shaped strips or blocks of wood which are secured end wise in the said
dovetail grooves by means of screws passing through plates forming end flanges at
top and bottom of the drum.
The centre part of the drum is so shaped at both ends that either end is adapted
to bear on the part of the base plate or other surface upon which the drum turns, so
that when the drum gets worn, at the lower part it can be easily lifted off the
centre pin, even by an unskilled person, and reversed, that is to say turned upside
down so that the worn part may be at the top and the unworn part brought into
action at the bottom.
My invention is illustrated in the accompanying drawings in which Figure 1 is a
vertical section on line Y-Y of Figure 2 and Figure 2 is a horizontal section on
line X-X of Figure 1.
A is the base plate adapted to be secured to the deck for example by means of
holding-down bolts passing through the holes a. B is a boss on the upper side of
the base plate A into which is secured, by keying or otherwise, the centre spindle C
on which the drum D revolves as shown. E are dovetail grooves into which are
fitted the wooden strips or blocks F, which are secured end wise by means of
screws G passing through the plates H which form end flanges at the top and
bottom of the drum. If desired the ends of the strips or blocks F may be made
to take into suitably shaped recesses formed in the said plates or flanges H. The
outer faces of the strips or blocks F may be shaped to a concave curve as shown
in Figure 1, and they may be beaded or sheathed with metal f to protect them
more or less from wear and tear.
It will be seen that the centre part of the drum D is so shaped at the ends d
that it can easily be reversed or turned upside down when worn at one part as
hereinbefore explained, either of the ends d being allowed to rest on the recessed
top of the boss B on the bed-plate A as required. When the strips or blocks F
become worn they can readily be renewed.
J is an oil box of any suitable material mounted on the upper end of the
spindle C, and provided with pipes or channels K for conveying oil automatically
to the working parts as shown. L is a stationary washer plate keyed or otherwise
attached to the fixed spindle C, and M is a cover plate attached to the plate H or
otherwise for protecting the working parts from dirt etcetera. N is a plugged hole
through which the oil box J may be re-charged when necessary.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. In a revolving warp-guide, bollard, or fair-leader, the use of replaceable
strips or blocks of wood substantially as described.
Second. In a revolving warp-guide, bollard, or fair-leader, the use of replaceable
strips or blocks of wood fitted into dovetail grooves in the drum of the warp-guide,
bollard, or fair-leader, substantially as described with reference to the accompanying
drawings.
Third. In a revolving warp-guide, bollard, or fair-leader the use of a reversible
drum, substantially as herein before described with reference to the accompanying
drawings.
Fourth. In a revolving warp-guide, bollard, or fair-leader the use of lubricating
arrangements, substantially as described with reference to the accompanying
drawings.
Fifth. The improved warp-guide, bollard, or fair-leader constructed and operating

page_text: substantially as hereinbefore described with reference to the accompanying
drawings.
