We ERNEST ALFRED VEALE of 17 Pier Road Gravesend in the County of
Kent Master Mariner and WILLIAM RODGER HAYES of 46 Raymond Road
Upton Park in the County of Essex, Shipwright, do hereby declare the nature of
this invention to be as follows:-
Briefly described the invention consists of a horizontal indicator formed by two
uprights containing sheaves in their upper extremities, and a crosspiece joining
these upper parts of the uprights together. This crosspiece is graduated in
degrees from the middle on either side to 45 degrees or to the maximum helm
angle. The size of the indicator to be regulated by the accommodation offered in
different ships and also by the range of their rudder chains, but wherever possible
each degree of helm to move the pointer on the indicator a space of from one to twe
inches. This pointer consists of a wooden block or other device with pointer
attached travelling in a groove in the horizontal crosspiece of the indicator and
connected to & worked by a small flexible steel wire or chain which passing through
suitable leads is connected to the rudder-chains where most convenient and in such
a manner that when the helm is amidships the pointer of the indicator stands at
zero or at the centre of the indicator and when the helm is put over to starboard or
port the pointer travels to starboard or port and registers on the scale which is
placed on the bridge of the vessel the exact angle to which the rudder is actually
moved.
In vessels where hydraulic or other gearing is used and there are no wheel chains
to connect to, a light quadrant is constructed on the rudder head and the wires or
chains lead in two grooves on the after part of the quadrant on the same principle
as rudder chains are usually worked. These wires or chains are set taut by means
It is to be understood that the nature or form of the device for
automatically moving the indicating device or pointer is not confined to the one
more particularly described but any suitable mechanism may be used by which the
function specified can be effected; however the means here specified may be used
in ordinary cases.

Improvements in Means for Indicating the Position of the Rudder
on Board Ship.
We,
ERNEST ALFRED VEALE, of 17 Pier Road, Gravesend, in the County of
Kent, Master Mariner, and WILLIAM RODGER HAYES, of 46 Raymond Road,
Upton Park, in the County of Essex, Shipwright, 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:-
Briefly described, the invention consists of a horizontal indicator formed by two

page_text: uprights containing sheaves in their upper extremities, and a crosspiece joining
these upper parts of the uprights together. This crosspiece is graduated in
degrees from the middle, on either side, to 45 degrees, or to the maximum helm
angle. The size of the indicator to be regulated by the accommodation offered in
different ships, and also by the range of their rudder chains, but wherever possible
each degree of helm to move the pointer on the indicator a space of from
1 to 2 inches. This pointer consists of a wooden block, or other device, with
pointer attached, travelling in a groove in the horizontal crosspiece of the indicator,
and connected to and worked by a small flexible steel wire or chain, which passing
through suitable leads, is connected to the rudder chains where most convenient,
and in such a manner that when the helm is amidships the pointer of the indicator
stands at zero, or at the centre of the indicator, and when the helm is put over to
starboard or port it registers on the scale, (which is placed on the bridge of the
vessel) the exact angle to which the rudder is actually moved.
In vessels where hydraulic or other gearing is used, and there are no wheel
chains to connect to, a light quadrant is constructed on the rudder head, and the
wires or chains led in two grooves on the after part of the quadrant, on the same
principle as rudder chains are usually worked. These wires or chains are set taut
by means of a screw!
It is to be understood that the nature or form of the device for automatically
moving the indicating device or pointer, is not confined to the one more particularly
described, but any suitable mechanism may be used by which the function
specified can be effected; however the means here specified niay be used in ordinary
cases.
In the drawings annexed hereto Fig. 1. shows the general arrangement when
used with a quadrant on the rudder head. A. is the deck of the bridge, on which
the two columns B B. are placed in front of the steersman, on the top of these
columns there is a suitable device for carrying pulleys C. C, the top ends of the
columns being connected together by a frame D. made of metal, wood, or other
material and of any suitable shape, in this frame there is a slotted opening E. to
allow the pointer to travel to and fro. This pointer F is connected to the chain
or wire G which runs on the pulleys C. C. and is led to the stern of the ship as
necessary to the quadrant H. placed on the rudder head, the wire or chain being
furnished with suitable tightening screws I. I. Or in other cases the wire or
chain G may be connected to the rudder chains, one wire being connected to the port
side and one to the starboard side. The cross frame D. which connects the top of
the two columns B. B. is suitably marked off, or has a scale suitably marked off, in
degrees or spaces on each side from the centre.
Fig. 2 shows the pointer F. and where the wire or chain. G is gripped, with a
movable lamp L for night work, hooked on to the pointer F at K, so that the
indicator can be seen at night, the lamp travelling to and fro with the pointer.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The improved means for indicating the position of the rudder on board ships
substantially as described and shown in drawings.
2. In the improved apparatus, substantially as described, the method of
illuminating the scale by means of a lamp attached to the pointer and moving with
same.
