I, WILLIAM CHADBURN, of 11, Waterloo Road, Liverpool, in the County of
Lancaster, Optician do hereby declare the nature of the said invention for
IMPROVEMENTS IN AND IN CONNECTION WITH TELEGRAPHING AND TELEGRAPHING
APPARATUS USED IN CONNECTION WITH ENGINES to be as follows:-
This Invention has for its object the better and fuller transmission and indication
of certain telegrams used in connection with engines, more particularly of ships,
that is such as those in and between the engine and engine room and the
bridge, or transmitting instrument, under the control of the then navigator or
commander.
This Invention consists of certain improvements in and in connection with
engine telegraphs which I will now describe.-In connection with a portion of the
reversing gear of the engine (reversable) I arrange a device which operates an
indicator, or indicating mechanism. This device is also arranged in connection
with the throttle, or other steam governing valve, or mechanism. The device
above mentioned may be termed an alternator; as according to the direction in
which the engines are set and if the steam supply is open, so the device causes an
alternate movement of the indicating mechanism when orders are carried out
namely either in one direction, or the other; whilst, if either the steam be cut off,
or the reversing mechanisin of the engine be in a neutral position, or both are in
a neutral position, the indicating mechanism will also show or stand in a neutral
position and so long as the steam is cut off the indicator will stand at a neutral
position whatever the position of the alternator may be.
An arrangement of connections and apparatus suitable for carrying the before
mentioned improvements into effect may consist as follows. I will take a case of
a marine engine as an example having a throttle valve for a steam governing, or
controlling mechanism and the ordinary link and eccentric arrangement as a
reversing mechanism, or gear, the link being operated from drag links, lever and
wiper shaft, such as those commonly employed in marine engines. The alternator
consists of a radial link which is connected with both a part of the reversing gear,
such as the wiper shaft lever, and the throttle valve thus it has a combined
connection. The connection with the throttle valve may be made through two
rods, or bars which are connected to the link one at each end, the opposite ends of

page_text: the rods, or bars being connected to a lever upon or in connection with the throttle
valve. In the link slot works a pin which is formed upon a lever which is so
arranged in connection with the indicator that when the throttle valve is closed
the pin assumes a central position and the indicator stands at a neutral point on
the indicator dial whatever the position of the reversing gear but when the throttle
valve is wholly, or partly open the pin will stand at, or towards one or the other
end of the link, according to the position given to the main links of the engine and
according to the extent to which the links may be set, or thrown over in one
direction, or the other; the pin will thus be depressed, or raised as the case may
be and this movement is transmitted through a lever, or other suitable apparatus
to the indicator. The indicating apparatus may be of suitable construction and
formation for example it may be provided with a finger and dial on which are
marked the required points. The movement of the above described apparatus is
transmitted to an indicating device upon the bridge or other part of the ship
where it may be required, so that the indication made in the engine room is
transmitted and repeated to this part. This latter indicating mechanism may form
an apparatus of itself, or it may be applied to the ordinary bridge and engine room
telegraphing apparatus.

Telegraphing Apparatus Used in Connection 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 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 the better and fuller transmission and indication
of certain telegrams used in connection with engines, more particularly of ships,
that is such as those in and between the engine and engine room and the
bridge, or transmitting instrument under the control of the then navigator, or
commander.
This Invention consists of certain improvements in and in connection with
engine telegraphs which I will now describe.-In connection with a portion of the
reversing gear of the engine (reversable) I arrange a device which operates an
indicator, or indicating mechanism. This device is also arranged in connection
with the throttle, or other steam governing valve, or mechanism. The device
above mentioned may be termed an alternator; as according to the direction in
which the engines are set and if the steam supply is open, so the device causes an
alternate movement of the indicating mechanism when orders are carried out,
namely in either one direction, or the other, whilst if either the steam be cut off,
or the reversing mechanism of the engine be in a neutral position, or both are in
a neutral position, the indicating mechanism will also show, or stand in a neutral
position and so long as the steam is cut off the indicator will stand at a neutral
position whatever the position of the alternator may be.
The above description sets forth my Invention generally, but that the same may
be clearly understood, I will now proceed to describe the same more definitely by
the aid of the sheets of Drawings making a part of this Specification which
together with the following description are sufficient to enable others skilled in the
art to which it appertains, or with which it is most nearly connected to make, use
and put the same into practice. The Drawings are marked with letters and figures
of reference which correspond with those used in the Specification, like letters and
figures being used to denote the same, or corresponding parts throughout the
various views and figures.
DESCRIPTION OF THE DRAWINGS.
Figures 1. 2 and 3 illustrate a telegraphing apparatus of a ship suitable for
carrying the improvements in telegraphing according to this Invention into effect.
Figure 4 shows the telegraphing apparatus applied to marine engines.

page_text: marine engine as an example having a throttle valve at C for a steam governing,
or controlling mechanism, or gear, and the ordinary link a and eccentric arrange-
ment, as a reversing mechanism, or gear, the links being operated from drag
links a lever A and "wiper shaft A¹. B designates the alternator which consists
of a radial link which is connected with the wiper shaft lever A by a rod b and
the throttle valve C, thus it has a combined connection. The connection with the
throttle valve may be made through two rods, or bars c which are connected to
the link B one at each end, the opposite ends of the rods, or bars being connected
to a wrist D which is connected with the throttle valve through the rod d. The
movement of the wrist is controlled by a stop pin e. In the link slot works a
pin which is formed upon the lever g which is so arranged in connection with
the indicator by the rack and tooth gear i that when the throttle valve is closed
the link B assumes such a position that no movement will be given to the lever g
whatever the position of the engine reversing gear, and the indicator h which is
applied to the bridge instrument E stands at a neutral point on the indicator
dial h¹ whatever the position of the reversing gear A; but when the throttle
valve C is wholly, or partly open the pin f will stand at, or towards one, or the
other end of the link according to the position given to the main links of the
engine and according to the extent to which the links may be set, or thrown over
in one direction, or the other. The pin f will thus be depressed, or raised as the
case may be and this movement is transmitted through the lever g, the rack and
tooth gear i to the indicator by a cord, or chain . The indicating apparatus
shown, is of suitable construction and formation and is provided with the finger h
and dial h¹ on which are marked the required points. The movement of the
above described apparatus is preferably transmitted to an indicating device E' in
the engine room as well as upon the bridge (see Figure 4) or other part of the ship
where it may be required, so that the position of the reversing gear and the steam
supply is indicated in the engine room and is transmitted and repeated to the
transmitting, or bridge instrument E. This latter indicating mechanism may form
an apparatus of itself, or it may be applied to the ordinary bridge and engine
room-telegraphing apparatus.
Having now particularly described an 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 telegraphing herein described which consist essen-
tially in effecting the indication upon the bridge, or other portion of a vessel, the
position of the reversing mechanism of an engine combined with the condition of
the steam controlling, or governing device.
Second. The combination with means for indicating upon the bridge, or other
part of a navigable vessel, the position of the reversing gear of the engines, of a
device for telegraphing and indicating the position of the steam controlling, or
governing device to said bridge, or other part substantially as set forth.
Third. In combination with the reversing gear of a steam engine and the steam
controlling, or governing apparatus, the device for telegraphing the position of such
steam controlling apparatus substantially as set forth with reference to the
Drawings or any mere modification thereof.
