and Daniel M° Phee at the Office of the Commissioners of Patents,
with their Petition, on the 20th May 1878.
We, RICHARD WILKINSON HAILSTONE, Naval Architect, and DANIEL
M° PHEE, Iron Master, both of Hull, in the County of York, do hereby
declare the nature of our said Invention for "A NEW OR IMPROVED SHIP'S
TELEGRAPH AND INDICATOR," to be as follows:-
This Invention has for its object the transmission or conveyance of
signals from the captain, pilot, or other person in the charge of ships
to the man at the wheel, in a perfectly reliable and unmistakable
manner, while at the same time by the arrangements herein described,
the signal given will will be repeated on an indicator in the view
of the captain or other officer, who will then see that his command was
correctly given and obeyed.
This Invention will be found more particularly useful in steamers

page_text: having their wheels in a deck or wheel house or under a bridge far aft
from the officer in command, and more especially when blowing hard or
in bad weather.
Our Invention consists in the correct transmission and repetition of
signals by the following mechanical arrangements, that is to say, the
telegraphing to the man at the wheel is effected in the following
manner: A lever handle for operating the telegraph is connected to a
second lever; these levers are fixed in a box of wood or iron. The two
levers work loose on bolts within the box. The first lever has a forked
end with slot. The upper end of second lever is fixed into this forked
end, and a bolt passing through the slot and end of second lever allows
the levers to be worked to suit the dial. At the top of the box there
is a slot hole to allow the lever to traverse from side to side, and
on the outside of the box at the top where the slot is, a brass plate
whereon is engraved "port" steady," and "“starboard.” At the
lower end of second lever are two holes, in which are inserted two
bolts to which is secured a wire rope communicating with the pointer
on dial in the wheel house, or wherever the wheel may be placed.
Small sheaves placed in suitable positions to conduct the wire rope to
the dial.
r
The dial is made in the following manner :-A box of suitable
dimensions has placed in the inside a gong, and inside of gong are two
hammers with springs and catches. The wire rope is connected between
the levers in operating box, and a lever inside of dial box with gong.
On the face of lever last named are two catches in positions suitable to
raise the hammer as it passes; when the catches have passed the pro-
jecting parts on lever the hammer strikes the gong and a pointer has
indicated in what position the helm is required.
The response to the signal is effected in the following manner :—The
spindle of wheel has upon it two studs, and to these studs are connected
two wire ropes.
These wire ropes lead to a pulley and are connected
therewith by two studs. The pulley is keyed on a bolt, also the internal
end of the bolt is carried by a partition running from side to side of the
operating box, and to the bolt is keyed a small pinion wheel, which
pinion works in a half wheel keyed on a bolt which passes through the
box so as to receive a pointer. Thus, when orders are telegraphed from

page_text: lever on deck house or bridge to the man at the wheel, directly he obeys
by turning the wheel the captain sees by indicator if he is obeyed
correctly.
We propose to conduct our wires fore and aft in metal or iron pipes
passing through the beams.
