with Engines.
I, WILLIAM CHADBURN, of 11 Waterloo Road, Liverpool, in the County of
Lancaster, Optician do hereby declare the nature of my said invention to be as
follows:-
My Invention relates to improvements in telegraphing apparatus used in connection
with engines, more particularly marine engines and has for its object a simple and
inexpensive construction of engine tell tale, or transmitter direct from the engine, of
the carrying out of orders given by the ordinary telegraphing instruments to the
engineer in charge of the engines.
To this end my Invention consists in providing what is commonly known as the
wiper shaft, namely that shaft by which the valve levers are worked and upon which
the starting levers are mounted, or the usual equivalent to such wiper shaft with a
disc, or lever, or levers, or their mechanical equivalent. I connect this disc,
or lever, or levers, or their mechanical equivalent by means of a chain, cord, or
band, or by chains, cords, or bands, or by rods,. or by combined chains or cords, or
bands and rods with a tell tale pointer on the telegraph transmitting instrument in
such a manner that the position of the wiper shaft, or its equivalent is recorded
automatically by the engine and without the intervention of the engineer by the tell
tale pointer on the dial of the transmitting instrument, thus if the engine is going
ahead, such is indicated from the engine by the position of the wiper shaft and
through the connections by the tell tale pointer on the dial of the transmitting
instrument; in like manner if the engine is going_astern, the direction is recorded by
the tell tale pointer.
By mounting the operating gear in connection with the tell tale pointer, directly on
the wiper shaft, I am enabled to greatly simplify and reduce the cost of tell tale
telegraphs, actuated direct from the engine.

Lancaster, Optician, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My Invention relates to improvements in telegraphing apparatus used in connection

the engine, of the carrying out of orders, given by the ordinary telegraphing
instruments to the engineer in charge of the engines.
To this end my Invention consists in providing what is commonly known as the
wiper shaft, namely that shaft by which the valve levers are worked and upon which
the starting levers are mounted, or the usual equivalent to such wiper shaft with a disc,
or lever, or levers or their mechanical equivalent. I connect this disc, or lever, or
levers, or their mechanical equivalent by means of a chain cord, or band, or by chains,

tell tale pointer on the telegraph transmitting and receiving instruments, in such a
manner that the position of the wiper shaft, or its equivalent is recorded automatically
by the engine and without the intervention of the engineer, by the tell tale pointer on
the dials of the transmitting and receiving instruments; thus if the engine is going
ahead such direction is indicated from the engine by the position of the wiper shaft
and through the connections by the tell tale pointer on the dials of the transmitting
and receiving instruments; in like manner if the engine is going astern, the direction
is so recorded by the tell tale pointer.

The annexed Drawing illustrates an example of a marine engine provided with
telegraphing apparatus with my Improvements applied thereto. a is the wiper shaft
by which the valve levers are worked. is a disc which I fit on the wiper shaft.
the telegraph transmitting instrument situated on the bridge, or in any other con-
venient position. d is the receiving instrument situated in the engine room. These
instruments are of the usual construction and are provided with the usual connections
and tell tale pointers. In addition to these I provide a connection which may be an
endless chain e, or its equivalent. This chain e is connected to the disc bon the wiper
shaft a and is led over suitable pulleys and is connected to the tell tale pointer i of the
transmitting instrument e and the tell tale pointer of the receiving instrument d in
any suitable way.
In action if the engine is going ahead, such direction is indicated by the tell-tale

page_text: pointers and h of the instruments c and d by reason of the position of the wiper
shaft a and the disc b. In like manner if the engine is going astern the direction is
recorded by the tell-tale pointers i and h.
By mounting the operating gear in connection with the tell-tale pointer, directly on
the wiper shaft I am enabled to greatly simplify and reduce the cost of tell-tale
telegraphs, actuated direct from the engine.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :
First. The improvements in Ships Telegraphs herein set forth.
Second. The combination with the wiper shaft a of a disc band connection e
arranged and operating as and for the purposes herein set forth.
