Complete Specification Accepted, 4th May, 1889
I JOSEPH PANNELL GIBBINS of 4 Osborne Terrace, Coombe Farm Lane Westcombe
Park in the County of Kent Submarine Mining and Electrical Engineer do hereby
declare the nature of this Invention to be as follows:-
My Invention has for its object to provide a ground mine for marine or land purposes
which can be readily and safely filled to its full capacity with granular explosives such
for example as gunpowder.
I provide a circular case with a lid or cover which is secured or screwed down
upon the main body of the casing and is provided with an orifice through
which the case containing the mechanism for testing and firing the mine is passed
and in which it is secured. The said lid or cover is provided with a filling orifice
preferably bushed with gun metal and through this after the lid or cover is in place
the casing is filled up with the granular explosive by a suitable funnel which is then
removed and the orifice is closed by a plug secured or screwed therein. The
bottom of the casing is made of a dished or dome-shaped section to give secure
anchorage.
I have described the lid or cover as being made separately but it may be cast in one
with the other parts of the case if desired.

Improvements in Ground Mines for Sea and Land.
I JOSEPH PANNELL GIBBINS of 4 Osborne Terrace Coombe Farm Lane Westcombe
Park in the County of Kont Submarine Mining and Electrical Engineor 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 :-
My Invention has for its object to provide a ground mino for marine or land
purposes which can be readily and safely filled to its full capacity with granular
explosives such for example as gunpowder."
Figure 1 of the accompanying drawing represents in vertical section and Figure 2
in plan a ground mine casing made according to my invention I provide a circular
case A with an opening at a at is upper side which opening I cover with a ring lid or
cover B which is secured or screwed down upon the main body of the casing. This
may conveniently be effected by screw bolts and nuts as at a². The said lid or cover B
is provided with an orifice & through which the case containing the mechanism for
testing and firing the mine is passed and in which it is socured. The said lid or
cover or the upper side of the box outside the said lid or cover (which latter is the
plan shown in the drawings) is provided with a filling orifice at c preferably bushed
with gun
metal. The bushing is most conveniently made in the form of a screwod
tube with nuts serowed on at top and bottom which nuts may have washers
between them and the casing A (or the lid B if the orifice be in the lid) to make a
tight joint. Through this orifice e after the lid or cover B and case containing the
mechanism are in place the using is filled up with the granular explosive by a
suitable funnel which is then removed and the orifice is closed by a plug or cap d
secured or screwed therein or thereon.
The bottom of the casing A is made of a dished or dome shaped section as shown
at A' to give secure anchorage.
I have described the lid or cover as being made separately and secured to the
case A but it may be cast in one with the other parts of the case A if desired,
whero the mine is one small enough to allow of the arm of a man reaching through
the opening to the bottom and sides of the interior of the casing. This is shewn in
Figures 3 and 4 where the parts which correspond with those shown in Figuros 1 and 2
are marked with the same letters of reference.
Having now particularly described and ascertained the naturo of my said invon-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A ground mine casing having a lid containing a separate aperture for enabling
the casing to be couveniently charged with a granular explosive and having also an

page_text: aperture 6 therein for inserting the testing and exploding mechanisin substantially as
described with reference to figures 1 and 2.
2. A ground mine casing having a lid aperture 6 cast in the top and having a
separate aperture for enabling the casing to be conveniently charged with a granular
explosive substantially as described with reference to Figures 3 and 4.
3. Forming the casing of ground nines with a concave bottom to give secure
anchorage substantially as hereinbefore described and shewn at A' in the accompanying
drawings.
