PROVISIONAL SPECIFICATION.
Improvements in Warp-guides, Dandy-scores, and the like.
I, JAMES INCHES, of 17 Cavendish Street, Grimsby in the County of Lincoln,
Engineer, do hereby declare the nature of the said invention, to be as follows:-
This invention relates to improvements in warp-guides or dandy-scores, such, for
example, as are employed on board of trawlers for the purpose of guiding the warp
from the winch and fair-leaders over the side of the vessel to the trawl. These
warp-guides or dandy-scores commonly consist of a horizontal bollard mounted on
a carriage which turns on a centre pin attached to a fixed bed-plate the centre
pin also serving as a spindle on which revolves a vertical bollard. In warp-guides
or dandy-scores so constructed the horizontal bollard and its carriage move very
stiffly and frequently jam, causing considerable wear and tear on the before-
mentioned vertical centre pin which is consequently liable to break off.
According to my invention I form a cylindrical or other suitably shaped boss on
the under-side of the said carriage and I fit this boss into a corresponding hole in
the fixed bed-plate and cause it to revolve therein. I also form a projecting boss
preferably of a truncated conical form on the upper side of the said carriage to
receive and steady the lower part of the vertical bollard; the vertical bollard,
and carriage of horizontal bollard both revolving upon a vertical spindle, which is
carried through and bolted or otherwise secured under the bed-plate.
I also sometimes place the vertical bollard eccentric with reference to the centre
on which the carriage of the horizontal bollard revolves. In this case the vertical
spindle carries the vertical bollard only, the carriage of the horizontal bollard
revolving on its boss in the hole in the bed-plate.
Dated this 27th day of September 1895.

I JAMES INCHES, of 17 Cavendish Street, Grimsby, in the
County of
Lincolnshire, 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 :-
This invention has for its object to improve warp guides, dandy scores and the
like, used for trawl gear on board steam or sailing trawlers, in order to reduce wear
and tear on the rollers employed, and to give the rollers automatic adjustment for
the purpose of leading a warp from all points of the compass.
In carrying out my invention and in lieu of the horizontal roller being carried
in a separate swivel frame bearing, I fix it on the same cast iron base or carrier
plate as the vertical roller. I also arrange the carrier or base plate, so that it can
revolve or turn on a centre spigot or boss on its under side, which fits into a
corresponding hole or recess in a strong sole plate. I fix the vertical roller on top
of the carrier or base plate in such a position that the centre of the vertical roller
does not coincide with the centre of the base plate, but is excentric to it. By
these means, in addition to the vertical roller revolving on its own centre, it has a
planetary path of rotation round a fixed centre; this induces the horizontal roller
to take up a central position to the warp, which prevents the wire from scoring
and cutting the cleats forming the bearings of the roller.
I also arrange stays to the vertical roller, so that they are always in a position
so resist the strain on the roller; and whereas the stays have always the same
movement as the carrier or base plate, they cannot interfere with the movement
of the horizontal roller, which can therefore travel round to all points of the
compass.
The dandy score can either be fixed or carried on the rail and bulwarks of a
vessel, or may be fixed to a pedestal built up from the vessels deck.
In order that my said invention and the manner of performing the same may be
properly understood, I hereunto append a sheet of explanatory drawings, to be
hereinafter referred to, and shewing my improvements in warp guides, dandy ecores
and the like, and in which the same letters refer to corresponding parts in the
various figures.

Figure 1, is a sectional elevation of the improved dandy score. a, is a strong
cast iron base or carrier plate which revolves in a horizontal plane around a fixed
centre d. The base a, carries the vertical roller and the horizontal roller h. The
rollers and revolve around spindles or pins c and g, but these rollers retain a
fixed position in relation to the carrier or base plate a. The base plate a has a
strong spigot cast on its under side at d, which serves as a centre on which it
turns; the centre c of vertical roller t, is however not concentric with centre d, but
is fixed excentric, so that in addition to the revolution of roller around its own
centre c, it possesses a planetary movement around centre d, depending on the
radial distance between centres c and d. The vertical roller v, is recessed at the
bottom and revolves on a spigot or boss which is a
part of base a, thus considerably
reducing the strain on spindle c. f and are guide cleats for warps passing over
roller h. is a wrought iron stay which retains a fixed position in relation to
rollers and . is a strong cast iron sole plate in which e are bolt holes for
fixing the dandy score in place. kis a plate with screw to draw and keep base a
on the sole plate b.
The sole plate can be made of any depth, or in the form of a pedestal extending
to the deck of the vessel.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it to be understood
that I am aware of the specification of Thomas Sudron and Alfred Sudron No. 17819
of 1892, and that I do not claim anything described and claimed therein; but I
declare that what I claim is 1-
1. In connexion with warp guides, dandy scores and the like, constructing a
dandy score with circular base or carrier plate, having a vertical roller v and a
horizontal roller h, the whole capable of turning or revolving on a spigot or
centre d, to any point of the compass, substantially as and for the purposes.
described.
2. The application of a vertical roller t, with a recess at bottom working on a
spigot or boss around centre spindle c, which is fixed excentrically to centre
spigot d, of base a, & with stays s, which allow an all round motion to horizontal
roller h, substantially as and for the purposes hereinbefore described.
3. The combination of the parts constituting improved dandy scores, substantially
as and for the purposes herein before described.
