COMPLETE SPECIFICATION.
Improvements in or connected with Revolving Warp Guides,
Bollards, Fairleaders, and the like.
We, ELIAS GEE FIELDS of 153 Stanley Street, Grimsby, Engineer, and THE
GREAT GRIMSBY COAL, SALT AND TANNING COMPANY, LIMITED, of Fish
Docks, Grimsby, 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:—
Heretofore, so far as we are aware that part of revolving warp guides, bollards,
fairleaders and the like which is arranged to rotate on the centre pin has been
made in one piece, that is to say with its top, bottom and body cast in one
piece, so that when the body part has become worn and cut into grooves and lanes
by the
rope used in hauling, the whole appliance, except the fixed bed, and centre
pin has had to be renewed. The present invention consists in forming the top,
bottom, and body in separate pieces, so that when the body part has become
worn it may be replaced by a fresh one the top and bottom parts being continued
in use.
And in order that the said invention may be fully understood we will now
proceed to describe the same with the aid of the accompanying sheet of drawings,
in which
Figure 1 is an elevation of a revolving warp guide, bollard, or fairleader
constructed in accordance with the invention, Figure 2 a sectional elevation of the
same,
Figure 3 a sectional plan taken on the line X X of Figure 2, and
Figure 4 a plan with the cover plate removed.
A is the bed plate which is fixed to the deck of the ship or other foundation in
the usual way.
B is the centre pin or axis keyed, or otherwise firmly secured in the
centre of the bed-plate A. C is a disc forming the bottom of the revolving part; it
rests on the centre boss of the bed-plate A and turns freely on the centre pin B. Dis
the body part adapted to fit at its lower end within the lip or flange C¹ surrounding
the disc C, and at its upper end within the lip or flange E¹ of a disc E forming the
top of the revolving part. This disc E rests on the top of the body part D, and is
adapted to turn freely on the centre pin B. The bottom disc C, the body part D
and the top disc E are bolted together by screw bolts F passed through the top and
bottom discs, and the revolving warp guide, bollard or fairleader thus produced is
prevented from being lifted off the pin B by means of a collar B¹ pinned on the
upper end of such pin. The three parts C, D and E are forced to turn together by
means of snugs D1, D2 cast at the bottom and top respectively of the body part D,
which engage with snugs such as C2 cast on the bottom and top discs C and E, or
by any other suitable means.
A cover plate G may be placed over all, and secured with set screws, or other-
wise, to the top disc E to make a neat finish and to protect the ends of the bolts F
and pin B.
It will now be understood that when the body part D becomes worn into grooves
or lanes by the action of the hauling rope it can easily be removed and a fresh one
applied in its place, by removing the nuts from the ends of the bolts F and
the collar B from the top pin B, then taking off the top disc E, removing the
body D, putting a fresh one in its place, replacing the top disc E and bolting up as
before.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. Constructing the revolving part of warp guides, bollards, fairleaders and
the like with the body part separate from the top and bottom parts, and securing
the three parts together, substantially as described.
Second. A revolving part for a warp guide, bollard, fairleader or the like,
consisting of a bottom, a top, and an intermediate or body part, means for
securing such parts together so that they can be readily separated, and means
for causing all the said parts to turn together, substantially as described.
Dated this 6th day of February 1895.
