I, WILLIAM LUND, of Fleet Street, in the City of London, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN SECURING
CASES CONTAINING BULLION AND OTHER VALUABLE PROPERTY, PARTS OF WHICH ARE
APPLICABLE TO THE SECURING OF BALES AND OTHER PACKAGES," to be as follows:-
1
The first part of my Invention consists in securing cases and packages,
in addition to any other means of securing the same, such as locks, screws, &c.,,
by bands of iron or other suitable metal, in such manner that any attempt
to open the case or package will be apparant..
The second part of my Invention consists in securing cases, boxes, and the
like, where wire or cord is passed round them, by means of a leaden disc with
rising arms, which are turned down and form a seal by an engraved punch
over the ends of the wire or cord, and secure the same from being undone or
separated unless the leaden seal is broken.
For the sake of clearly describing the manner in which I perform the first
part of my Invention, let us suppose it to be about to be applied to the out-
side of a case containing bullion. I take two bands of metal, by preference of
hoop iron, pass one of them round the ends and bottom, and the other
round the sides and bottom of the case, and thus get the four ends near the

page_text: centre of the top of the case; then I pass the four ends through a hollow,
square, and flat piece of metal, and hammer them, smartly back over the edge
of the square. Each end thus forms a loop or hook; in the formation of the
loop the fibre of the iron becomes so disturbed that any attempt to turn back
the loop in order to withdraw any of the ends from the square, will cause the
metal to break at the bend, and thus indicate the effort made to get at
the case. Should the iron not break on being turned up, it would hardly fail
to do so on the end being again turned down to form the loop as before. But
in order to give increased security, where the means before described are not
deemed sufficient, I hammer down a conical-sided nut formed to fit the square,
and thus jam the ends of the bands between it and the square, and secure the
nut by turning down a screw formed with a peculiarly shaped head through
the nut into the top of the case. The head of the screw is formed in such
manner that the sides of the slit thereon offer the usual resistance to a screw-
driver when being driven from left to right, while the slides of the slit are
sloped or thinned off so as to offer no hold to a screw-driver turned from right
to left; of course screws formed to drive in from right to left would have the
heads formed in the reverse manner to that before described.
Although I have only mentioned four ends of bands, yet it will be understood
that by changing the shape of the piece of metal over which they are bent to
form a loop, two, three, or more ends may be fastened in the manner described;
and again, a slot might be formed in one end of a band, and the opposite
end might be turned down and formed into a loop. The essential feature of
this part of my Invention consists in securing boxes and packages by means of
loops formed over a clasp, in such manner that the fibre of the metal shall be
so disturbed at the part where the loop is formed that it shall give or break
upon the same being turned straight, or, if not then, upon its again being
turned down to form a hoop.
