Improvements in Apparatus for Transmitting Orders, Notifications,
and the like from One Part or Station of a Navigable Vessel to
Another, and analogous purposes.
I, WILLIAM CHADBURN, of 11 Waterloo Road, Liverpool, in the County of
Lancaster, Telegraph Engineer, do hereby declare the nature of this invention to
be as follows :—
This invention has reference more particularly to the transmitting instruments
of ships' and analogous telegraphs, where the indicator or pointer and dial are
usually disposed in the horizontal plane at the top of the instrument, or to instru-
ments where the actuating device consists of a wheel or the like, which is adapted
to be revolved, or reciprocated to and fro, to move the pointer of the receiving
instrument, and its own pointer, the distance equivalent to one order, that is, from
order to order.
For convenience, the invention will be described chiefly with reference to ship's
telegraphic apparatus having a wheel adapted to be rotated, as referred to, for
actuating the instrument, such wheel being placed at the side of it.
According to this invention, to enable the order to which the apparatus has been
moved to be seen from the side, I provide a window or aperture in the wheel for
actuating the instrument, and behind it a disc or plate, also with an aperture or
window therein; while behind this a dial or the like is provided, having upon it the
names of the orders, notifications, or the like, this being adapted to be moved so as
to exhibit through the said windows or apertures the order, or the like, which will
have been transmitted to the receiving instrument. By this, there can be seen
from the side at a distance from the apparatus, as well as close to, the notification
which has been transmitted.
In some cases there may be used also on the opposite side of the machine a similar
or equivalent indicating part or parts; or, there may be used a pointer moving
over a vertical dial with the orders or the like thereon to indicate at that side the
order or notification or the like which has been transmitted. There may also be
used conveniently in connection with the means of indicating above described,
a lamp or the like for illuminating the orders or the like, or rendering them visible
at night, or at other times when desired.
There is, in some cases, used in connection with these moving dials, pointers, or
the like, devices by which they will be moved sharply from one order to another.
and positively to the central or correct and desired position, and will have a pause
or period of rest between these sharp and positive movements or actions.

and the like from One Part or Station of a Navigable Vessel to
Another, and analogous purposes.
I, WILLIAM CHADBURN, of 11 Waterloo Road, Liverpool, in the County of
Lancaster, Telegraph 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 reference more particularly to the transmitting instruments of
ships' and analogous telegraphs, where the indicator or pointer and dial are usually
disposed in the horizontal plane at the top of the instrument, or to instruments
where the actuating device consists of a wheel or the like, which is adapted to be
revolved, or reciprocated to and fro, to move the pointer of the receiving instrument,
and its own pointer, the distance equivalent to one order, that is, from order
to order.
For convenience, the invention will be described chiefly with reference to ship's
telegraphic apparatus having a wheel adapted to be rotated, as referred to, for
actuating the instrument, such wheel being placed at the side of it.
According to this invention, to enable the order to which the apparatus has been
moved to be seen from the side, I provide a window or aperture in the wheel for
actuating the instrument, and behind it a disc or plate, also with an aperture or
window therein; while behind this a dial or the like is provided, having upon it the
names of the orders, notifications, or the like, this being adapted to be moved so as
to exhibit through the said windows or apertures the order, or the like, which will
have been transmitted to the receiving instrument. By this, there can be seen
from the side at a distance from the apparatus, as well as close to, the notification
which has been transmitted.
In some cases there may be used also on the opposite side of the machine a similar
or equivalent indicating part or parts; or, there may be used a pointer moving
over vertical dial with the orders or the like thereon to indiente at that side the
order or notification or the like which has been transmitted. There may also he
used conveniently in connection with the mean ut indicating above describel, a
lamp or the like for illuminating the order, or the like, or rendering them visible
at night, or at other times when desired.
There is, in some cases, used in connection with these moving dials, printers, or
the like, devices by which they will be moved sharply from one order to another,
and positively to the central or correct and desired position, and will have a pause
or period of rest between these sharp and positive movements or actions.
Drawings illustrating these improvements are hereto annexed.
drawings
In these
Figure 1 is a sectional elevation of the head of a transmitting instrument
provided with my improvements.
Figure 2 is an elevation shewing one side of the instrument, and Figure 3 is an
elevation shewing the opposite side of the instrument.
Figure 4 is a plan shewing the upper horizontal dial of the instrument and its
pointer, and
Figure 5 shows the mechanism for operating the pointers of the instrument.
The example of transmitter given in the drawings is that wherein the actuation
of the telegraphic operator is affected through a wheel at the side, one revolution
of which is adapted to actuate the pointer of this instrument, as well as the receiving
intrument employed in connection with it, the distance only from one order to
another, that is one eighth of a revolution. An example of this type of apparatus

page_text: is set forth in a former Patent granted to me No. 1142 of 1890 and in the
Specification of application of the Patent No. 22391 of 1894.
Referring to the drawings, A. indicates the head of the transmitting instrument,
of which bis the actuating wheel, and c a part of the staud; while d shews the
transmission shafting by which motion of the transmitter is conveyed to the
receiving instrument. e is the horizontal pointer working over and in connection
with the upper horizontal dial el of the instrument. indicates the mechanism
by which the pointer e, and also the vertical pointer hereafter described at the
opposite side of the instrument, is actuated from the wheel b.
Regarding the side order indicator in connection with the wheel b, h is a dial
behind the wheel b containing the orders, which are inscribed upon it, such orders
being similar to those on the upper dial. In the wheel b, at the part which is
uppermost when in the normal position or position of rest, a window 6 is provided,
through which the orders behind it can be seen on the dial ; while to shield and
hide all the other orders on the dial , so as to prevent them being seen when the
wheel is being rotated, a fixed disc is provided on the fixed sleeve b³, which
supports the shaft, the said disc i having a window in it, at the upper part,
so that the window will be exactly behind that of the wheel when in this
position.

As regards the devices ff, through these the dial, the painter e, and the
pointer hereafter described, are all actuated. The disc is mounted on the
sbaft, which passes from one side of the instrument to the other, and the move-
ment given to the disc f by the disc f, is transmitted to the pointer e to the
shaft, which is driven by f¹, bevel wheels f³, and a spindle 4, carrying the
pointer e, and the upper bevel wheel 73. These devices consist of a disc f having
a tooth in it; and a disc f¹ with notches in it and parts between said
notches, the tooth being adapted to enter the notches of f¹ when fis rotated.
The outer edge of the parts are concave, and correspond in curvature to the
periphery of the disc f, and one of these concave parts engages with the periphery
off, whenever the tooth fx is not engaged with the parts f³. These devices f
are not only used to move the pointers e and indicators of the transmitter, but also
serve as a stop mechanism, acting in the same manner as the well known "Geneva
stop," by which the pointers e and as well as the receiver pointer, cannot be
moved further than over the full range of the orders or indications upon the dials.
To effect this, there being seven orders and six movements, the disc f¹ has six
notches or recesses and seven parts f, whilst the part between the adjacent and
last portions is left full and serves as a stopping part against which the
tooth fix of comes at the completion of its action, in either direction.
As regards the action of the dial h, to exhibit different orders from the
windows and 2, the dial is rotated, and this is effected by the shaft f2 by a
spur wheel thereon, and a similar spur wheel j' fixed to the side of the dial h, and
gearing with j. By this means, when the shaft 2 is rotated, the spur wheel j
with the dial are rotated upon the sleeve 63, and exhibit at said windows, when
the handle of the wheel b is in its normal or resting position, the uppermost order
or notification on the dial h, which will be the same as that which has been trans-
mitted to the other pointers, and this can be seen from a distance by the operator
or other person on the bridge or deck.
At the opposite side of the transmitter the other vertical dial k, having similar
orders on it to the others and a pointer k¹ is arranged. This pointer is moved by
the shaft through a spur wheel on 2, and a similar spur wheel ³ meshing
with, mounted on the spindle of the pointer. Thus, when the apparatus is
actuated by the wheel b, and the shaft revolved, the pointer revolves with
the other pointers referred to, and the position or order existing in the dial & can
be seen from this side of the instrument at a distance away from it; and further,
when the pointer (which is a folding one, having a hinge ) is extended, as
shewn, the position of the pointers and the orders which they are standing over

page_text: will be readily ascertained from either side of the instrument, by sight, from a
greater or less distance, by the position of the pointer k³.
It is to be stated that the improvements hereunder can be used separately, as
well as conjointly in ships telegraphic transmitters. For instance, the dial
indicator used in connection with the wheel can be used in lependently of the
other devices herein described; and conversely side vertical indicator can be
used in ships telegraphic apparatus having a horizontal dial as e independently of
the dial or other improvements described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a ship's telegraphic apparatus, wherein, in the transmitting instrument, a
wheel or handle is disposed in the vertical plane, and is adapted to be rotated one
revolution for each order transmitted, and a horizontal dial and pointer are
employed as the primary indicating means of the instrument, the employment in
connection wherewith of a secondary dial in the vertical plane, and a pointer
moving in connection therewith, and adapted to be moved to the amount of one
order to the other for each revolution of said wheel, substantially as described, by
which the point to which the receiver pointer has been moved will be visible at a
distance from the instrument, or the order approximately ascertainable.
2. In a ship's telegraphic apparatus, wherein in the transmitting instrument, a
wheel or handle is disposed in the vertical plane, and is adapted to be rotated one
revolution for each order transmitted, the employment of a rotating dial behind
said wheel, and a window or aperture in the wheel through which one of the orders
or notifications on said dial is displayed or seen, the said disc being moved from
one order to the other past the position of the window, in its position of rest, for
each revolution of the said wheel; operating substantially in the manner and for
the purposes described.
3. In rotary ships telegraphic apparatus of the type herein referred to, the
construction and arrangement of transmitting instrument, having the transmitting
wheel b, with the disc with orders on it, behind said wheel; and the dial k and
pointer arranged, constructed, and adapted to be operated particularly as set
forth with reference to the drawings.
