PROVISIONAL SPECIFICATION.
Improvements in or relating to Fixing the Lids of Air and Water
Tight Boxes.
I, STEPHEN WINCKWORTH SILVER, of Sun Court, Cornhill, London, Merchant,
do hereby declare the nature of this invention to be as follows:
This invention relates to certain improvements in fixing the lids of air and water
tight boxes known as African boxes, the object being to render the fastening more
ready for opening or closing the box and require less labour than by the present
system of fasteners employed.
For the purpose of this invention, I arrange a turn down bolt with claws having
eccentric faces on the front of the lid or front of the box next the meeting edges,
and by a lever forming part of the bolt and in most cases serving as the hasp of
the lock also, the claws can be caused to under-run or over run projecting lips,
studs, or pins and to gradually draw the lid into close contact with the water
and air tight lip of the box, this being effected by a rubber cushion secured in the
lid by flanges of metal strip soldered in place.

Improvements in or relating to Fixing the Lids of Air and Water
Tight Boxes.
I, STEPHEN WINCKWORTH SILVER, of Sun Court, Cornhill, London, Merchant,
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 relates to certain improvements in fixing the lids of air and water
tight boxes known as African boxes, the object being to render the fastening more
ready for opening or closing the box and require less labour than by the present
system of fasteners employed.
For the purpose of this invention, I arrange a turn down bolt with claws having
eccentric faces on the front of the lid or front of the box next the meeting edges,
and by a lever forming part of the bolt and in most cases serving as the hasp of
the lock also, the claws can be caused to under-run or over-run projecting lips,
studs, or pins and to gradually draw the lid into close contact with the water

page_text: and air tight lip of the box, this being effected by a rubber cushion secured in the
lid by flanges of metal strip soldered in place.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 perspective elevation from the front of one of the African boxes before
mentioned with the lid raised.
Figure 2 perspective sectional elevation of the box from one end.
A, outer body of box. 3, liner of same. C, air space. D) bead rim. E, raised
edge somewhat wide to ensure a broad bearing thereto. F, cushioned or plain
rubber strip inside lid G secured in position by metal strips H. I, closing bolt
on front of lid G with eccentric faced claws J, J, which when the lid is closed can be
forced under lips 1 of the head rim or under the bead rim to put pressure
against the rubber strip F and so make the meeting seams air tight when the lid
is closed. K, lever (hasp or other) by which the bolt I can be operated for both
opening and closing the lid G.
In the drawings I have shown an ordinary spring catch lock L, but any other
kind may be fitted, or staple and cover hasp for a padlock can be applied, if so
desired.
I have for convenience shown the African box with a back hinged lid G but the
same invention can be applied to side or end hinged lid boxes or to lids not hinged,
in which case the lid may have any number of my improved claw bolt fasteners for
securing it to the body A, and if desired the rubber cushioned or plain strips F
may be on the body of the box A and the compression may be from fillets of the
lid G.
The African box shown has a plain open interior but it may be provided with
partitions or shelves for keeping the contents separate and the better ready for
removal as found necessary. The spaces C may be filled with cork or the hair of
reindeer for lightness and buoyancy.
.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. Fitting box lids with eccentric faced claws J, J, of rotating bolt I for passing
under bead D or lips 1 for compression of rubber cushion strips in lid as shown
and for the purposes specified.
2. Providing metal boxes known as African boxes with inside cushioning seams
and outside compression claws for securing the lids to the bodies in the manner
described and substantially as represented on the annexed drawings.
