"
PROVISIONAL SPECIFICATION left by the said Richard Clarkson Scott at

the Office of the Commissioners of Patents on the 13th December 1882.
RICHARD CLARKSON SCOTT of Bankfield House Litherland near Liverpool in
the County of Lancaster "A SAFETY APPARATUS TO BE APPLIED IN SHIP'S HOLDS
This Invention bas for its object, a safety apparatus to be applied in ship's
holds.
The ladders by which ships holds are descended and ascended are usually carried
by stanchions or supports between the decks and clear of the hatchways.
This position is inconvenient and dangerous for the men but the ladders cannot
be otherwise placed in consequence of its being necessary that the hatch way
should be kept entirely free from obstruction for the loading and unloading
of cargo.
Falls from these ladders into the hold are of frequent occurrence.
To prevent such accidents I provide a folding cage which when the ladder is in
use can be raised into a position to protect the men in passing up and down.
For this purpose I fix two channel irons vertically in the hatchway, one on
either side of the ladder and to strengthen the structure cross bars of flat iron are
bolted to the backs of the channel irons. They pass across the stanchion ladder
under a ring midway between the combing. In the projecting flanges of these
channel irons holes are formed at intervals and these receive the ends of bars
forming parts of the cage. The back of the cage is composed of two vertical bars
connected by horizontal bars at intervals.
The horizontal bars pass through holes in the vertical bars and also through
holes or eyes in bars or links which form the sides of the cage.

page_text: Outside all these the ends of the horizontal bars are secured by split pins passed
through them.
The side bars at their other ends are bent at right angles, they are passed
through the holes in the fixed channel irons and are also secured by split pins
inserted through them.
The whole forms a cage or frame which when raised for use will protect the men
ascending and descending the ladders both at the sides and back of the ladders and
a man slipping on the ladder can at once steady himself by taking hold of any
part of the cage.
When not required for use the cage is lowered and it then folds in between the
channel irons and forms no impediment in the hatchway.
The upright bars at the back of the cage are, made in lengths which can be
disconnected the one from the other so that after the lower decks have been stowed
the portion of the cage serving the upper decks may remain in use.
A hand lever with suitable connections is applied for working the cage or it may
be otherwise raised when required and lowered out of the way when it is not
wanted.
At the intermediate decks I provide landing platforms they are when in use
supported on brackets and they fold down when they are not required.
The side bars of the cage opposite to these landing platforms are connected by
hooks to the back bar to permit them to be raised and disconnected in order that
the men may pass in and out of the cage from and to the intermediate decks.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Richard Clarkson Scott in the Great Seal Patent Office on the
13th June 1883.
RICHARD CLARKSON SCOTT of Bankfield. House Litherland near Liverpool in
the County of Lancaster "A SAFETY APPARATUS TO BE APPLIED IN SHIPS' HOLDS".
This Invention has for its object, a safety apparatus to be applied in ships'
holds..
r
The ladders by which ships' holds are descended and ascended are usually carried
by, stanchions or supports between the decks and clear of the hatchway..
This position is inconvenient and dangerous for the men but the ladders cannot
be otherwise placed in consequence of its being necessary that the batchway
should be kept entirely free from obstruction for the loading and unloading
of cargo.
+
Falls from these ladders into 'the hold are of frequent occurrence.
i
To prevent such accidents I provide a folding cage which, when the ladder is in
use can be raised into a position to protect the men in passing up and down.
Figure 1 is a front elevation and Figure 2 is a vertical, section of a safety
apparatus or cage constructed and arranged in the hold of a ship in accordance
with my Invention. Figure 3 is a section of a portion of the apparatus as it
appears when folded and out of use.
£
Figure 4 is an horizontal section on the line 1, 1, in Figure 1 and Figure 5
shows a landing platform. Figure 6 shows half size section of a channel iron..
At a b and c, the ships' decks are indicated, three only are represented but often
there are four, d is the bottom of the hold. eee are parts of the combings
around the hatchways. ff is the stanchion ladder it is shown in its ordinary
position on the aft side of the hatchway but the position may be varied. It is for
the protection of persons ascending and descending this ladder that my safety
apparatus or cage is applied.
For this purpose I fix two channel irons or channel bars g g vertically in the
hatchway, one on either side of the ladder (Figure 6 shows the section of the
channel iron) and to strengthen the structure cross bars of flat iron g¹ gl are bolted
to the backs of the channel irons. In the projecting flanges of the channel bars
holes are formed at intervals and these receive the ends of bars h h forming parts
of the cage. Or as is the case in the drawing the ends of these bars h may be
formed with eyes and bolts may connect them to the channel bars in such manner
as to leave them free to turn.
The back of the cage is composed of two vertical bars'i i connected by horizontal
bars kk at intervals.
The horizontal bars k pass through holes in the vertical bars i and also through
holes or eyes in bars or links h which form the sides of the cage. Outside all these
the ends of the horizontal bars k are secured by split pins passed through them.
The side bars has previously stated are provided with eyes at their other ends
or they may be bent at right angles, passed through the holes in the fixed channel
irons and secured by split pins inserted through them. The whole forms a cage or
frame which when raised for use will protect the men ascending and descending
the ladders both at the sides and back and a man slipping on the ladder can at
once steady himself by taking hold of any part of the cage.
When not required for use the cage is lowered and it then folds as seen in
Figure 3 in between the channel irons and forms no impediment in the hatchway.
The upright bars i at the back of the cage are made in lengths which can be
disconnected the one from the other by hand bolts or pins i¹ or other convenient

serving the upper decks may remain in use.
screw
To raise the cage for use the following arrangement of gear is often convenient.
1 is a screw carried in a suitable frame beneath the upper deck. m is a nut on the
v l.. m² m² are arms upon the nut they are guided at their ends in slotted
plates fixed, to the bars y and links pass from them to the ends of a pair of
levers n n which are mounted upon the channel irons g. The other ends of the
levers n are made to engage with one of the horizontal barsk. Thus when the
nut m is moved down upon the screw, the levers n turn about the joint pins which
connect them with the channel irons which serve as fulcra for the levers and the
cage is raised into a position to be a protection to a person descending by the
stanchion ladder.
In some cases especially in shallow ships where the weight of the cage is not
great a hand lever with suitable connections is applied for working the cage or it
may be otherwise raised when required and lowered out of the way when it is not
wanted..
At the intermediate decks I provide landing platforms, they are when in use
supported on brackets and they fold down when they are not required.
The platform consists of the following parts:-0¹ o' are a pair of hooks which
will. bang on the edges of.the hatchway combing.
The hooks are connected by two horizontal bars o² o² and brackets o³ o³ can
turn around their vertical stems. These brackets when the platform is in use serve
to support the floor grid o' which is connected with the hooks o', the outer bar of
the grid passing through lugs projecting from the hooks. 05 and o® are frames
covered with netting if considered desirable which turn up as guards as seen in
Figures 1 and 2 and are secured by a pin; they serve to prevent persons slipping
from the landing platform:
i
The side bars of the cage opposite to these landing platforms are connected by
hooks h¹ to the back bar to permit them to be raised and disconnected in order
that the men may pass in and out of the cage from and to the intermediate decks.'
pp are grip, handles which when the ladder is in use. can be clipped on to the
upper combing in the position shown by the drawing. Binding screws or other
fastenings may be employed to secure the grip handles..
リ
Having thus described the nature of my said Invention and the manner of
performing the same I would have it understood that I claim
My safety apparatus consisting of a cage constructed of bars jointed together
and, capable of being raised or opened out to surround the space about the ladder
by which the men ascend and descend and of folding out of the way when not in
use substantially as described.
In witness whereof I the said Richard Clarkson Scott have hereunto, set
my hand and seal this Eighth day of June in the year of our. Lord One
thousand eight hundred and eighty three.
