Improvements in Charge Receptacles or Cases for Submarine .
Ground Mines.
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:-
This Invention has for its object to provide cases or receptacles into which the
charge of a submarine ground mine can be more readily and expeditiously inserted
than is the case with the receptacles at present in use and by which the separate
sinking weights hitherto used are dispensed with.
According to this Invention the case is made so that one of its entire sides
preferably the top side can be removed for inserting the charge and after the charge
is inserted the said side or top can be securely fastened in position by screws or
other fastenings. The removable side where it constitutes the top of the case or
receptacle has an opening in which the case carrying the electrical apparatus
is inserted and fixed and also carries eyes or loops for the lowering and raising
tackle.
The sinking weights are formed as part of the case or receptacle itself preferably
taking the form of ribs cast upon the exterior of the case or receptacle.

Agent for the said Joseph Pannell Gibbins.

I, JOSEPH PANNELL GIBBINS of 4 Osborne Terrace Coombe Farm Lane Westcombe
Park in the County of Kent, Submarine Mining & Electrical 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 for its object to provide cases or receptacles into which the
charge of a submarine ground mine can be more readily and expeditiously inserted
than is the case with the receptacles at present in use and by which the separate
sinking weights hitherto used are dispensed with.
According to this Invention the case is made so that one of its entire sides
preferably the top side can be removed for inserting the charge and after the charge
is inserted the said side or top can be securely fastened in position by screws or
other fastenings. The removable side where it constitutes the top of the case or
receptacle has an opening in which the case carrying the electrical apparatus is
inserted and fixed and also. carries eyes or loops for the lowering and raising
tackle.
The sinking weights may be formed as part of the case or receptacle itself
preferably taking the form of ribs cast upon the exterior of the case or receptacle.
The accompanying drawing represents in vertical section in Figure 1 and plan in
Figure 2 a case or receptacle made according to my Invention as formed of cast
iron although the arrangement as far as removability of one entire side is concerned
is not limited to cases made of cast iron.
A is the case body and B is the removable side. C are the eyes or loops for
raising and lowering tackle. D is the opening for the electrical apparatus case,
and e are the screws or fastenings for securing the lid in place. b is a space for
packing material to ensure tight closure.
Having now particularly described and 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. A charge receptacle or case for submarine ground mines having the
whole of one of its sides entirely removable substantially as and for the purpose
herein before described.
Second. A charge receptacle or case for submarine ground mines having the
whole of one of its sides entirely removeable and having the sinking weights cast
thereon as ribs substantially as hereinbefore described and illustrated in the
accompanying drawings.
