PROVISIONAL SPECIFICATION.
Improvements in Slings for Lifting Shells.
We, Sir W. G. ARMSTRONG, WHITWORTH & Co. LIMITED, Manufacturing
Engineers, and JOSEPH HONNER, late Commander in the Royal Navy, both of
Elswick Works, Newcastle-upon-Tyne, do hereby declare the nature of this in**
vention to be as follows:-
The object of this invention is to enable shell to be lifted from shell bays
without necessitating the use of a bolt screwed into the shell or the necessity
for stowing shell with slings on them.
Under the usual conditions of stowage the shells are so close to each other
that it is impossible to put the hand between any two shells. To lift one end
of the shell is a tedious and difficult operation. For lifting the shells about, a
sling known as the band sling has been for some time in use.
This sling is
fitted with an eye rivetted to each end and when in place on the shell one eye
passes through the other but the eyes which are either cast or forged in metal
are too large to pass between the shells when the latter are stowed so that the
sling is useless for removing a shell from the bay.
According to our invention we make one of the eyes removeable fitting it with
countersunk lugs. To put the sling thus prepared round a shell it is only
necessary to introduce the thin end between two shells and turn the sling so
that the end shall pass downwards and below the body of the shell and then
again upwards on the opposite side and so coil itself round the body of the shell,
the loose eye can then be attached by letting the countersunk lugs enter into
suitable holes cut in the sling. The small eye is then passed through the large
eye in the usual way and the weight of the shell tends to make the engagement
of the countersunk lugs more efficient.

vention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:―
The object of this invention is to enable shell to be lifted from shell bays

of the shell is a tedious and difficult operation. For lifting the shells about, a
sling known as the band sling has been for some time in use.
This sling is

eye in the usual way and the weight of the shell tends to make the engagement
of the countersunk lugs more efficient.
Figure 1 of the drawings annexed shows an edge view of the fastening of a
sling and Figure 2 a side view while Figure 3 shows to a smaller scale the
method of putting the sling round a shell a while in place in the stack.
bis the band having an eye e rivetted to one end and at the other end holes d
to receive the lugs e on the removable eye f. It is convenient to attach the
eye f to the other eye c by means of a short chain fastened to the small eyes g.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:-
1. A sling for lifting shells in which one end is free to pass round the shell
and can be fastened to the other end by means of a detachable eye.
2. A sling for lifting shells in which one end is free to pass round the shel
and can then have a loose eye coupled to it to be passed through an eye on the
other end and form a handle by which the band and shell can be lifted, the
weight of the shell then keeping the loose eye securely locked to the band.
3. A sling substantially as described and shown.
