A communication by ADOLF SILBIGER, of IX Kolingasse 2, Vienna, in the Empire
of Austria, Gentleman.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of War-
wick, and 322, High Holborn, in the County of Middlesex, Civil 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:-
These improvements in collapsible boxes consist essentially in the arrangement
of improved devices for connecting the sides of the box when opened out and also
in the arrangement of the halves of the lid or cover on the sides so that the box
in its collapsed condition is completely protected. The invention also consists of
an improved means of fastening the lid which is so arranged that it may be
employed either when the box is ready for use or when it is in a collapsed condi-
tion. The lid fastened on the collapsed box thus forms an excellent protection for
the sides of the box which are folded one on the other, and imparts to the collapsed
box an extremely practical and convenient form so that the same occupies very
little space and is very portable.
In the accompanying drawings
Figure 1 is a longitudinal section of the box when extended and with the lid
closed;
Figure 2 is a partial plan view of the closed box;
Figure 3 a cross section of the box when in position for use;
Figure 4 is a longitudinal section of the collapsed box;
Figure 5 is a detail view of the method of connecting the sides one with another;
Figure 6 is a modified form of this connecting device;
Figures and 8 are details of the same;
Figure 9 is a view in perspective of a modified form of lid fastening for use in
connection with a different kind of lid, showing the box ready for use.
Figure 10 is a view in perspective of this lid fastening when the box is
collapsed;
Figures 11, 12, 13 and 14 are detail views of the fastening screws and nuts.
Referring to Figures 1-6 a b c d are the sides which are folded inwards on
hinges against the bottom f and which when the box is extended are held together
by means of inserted pins g which enter sockets h, Figure 5, in the sides a and
and engage in lugs i of the sides b and d. In order to insure the bars or pins
holding in the sockets h angle irons k, Figure 5, are screwed on said sides c and a.
The halves j of the cover or lid are pivoted, by means of pins 7 or hinges, on the

page_text: sides a and c and when the box is fastened said halves rest on projections or
supports m fixed on the sides b and d.
The fastening of the lid takes place by means of a bar o inserted through an
opening n of the side 6 of the box, which bar is pushed through a closed channel p
in one of said halves j of the lid and engages in a similar opening q in the side d.
The further securing of the bar o takes place by means of a seal s, the cord of
which is drawn through a lug t of the side b and through a hole in said bar o.
When the box is not in use the bars g and o are withdrawn and the sides
together with the parts of the cover connected therewith are folded together into
the position shown in Figure 4.
In the modified form of the mutual attachment of the sides shown in Figure 6
spring hooks u see detail view Fig. 8 are arranged in the sides a and c, which
hooks may be pressed up by means of studs v. Simple hooks w Fig. 7 are fixed
on the sides 6 and d. If the sides of the box are to be extended the spring hooks u
spring or snap over the hooks w the latter penetrating into recesses, thus holding
said hooks w fast, whilst the latter in turn find a firm hold on the edges y of the
plate. The sides which engage with one another are thus fastened in all directions..
If it be desired to collapse the box, the studs v are pushed outwards so that the
hooks u and w are released. As may be seen in the drawing all the hinges are
fixed in the interior of the box, so that the box by this means is fully protected
against any unauthorized opening.
.
In the modified form of lid and fastening shown in Figures 9-14, the lid, when
the box is in position for use (as shown in Figure 9) is secured, by means of
screws which pass through said lid or cover a¹ into sockets 61 fixed on the upper
edges of the sides d', the number and distribution of said screws being employed
as may be found most suitable. In order to fasten the lid a¹ on the collapsed box,
sockets fare arranged in a similar manner exactly beneath the sockets in the
edges e which come in contact, and the screws may be again in turn screwed
into the said sockets f' and thus the lid a' fixed down over the collapsed portions of
the box shown in Figure 2.
From the above explanation and by reference to the accompanying drawings it
will be readily seen that the sides are folded one over the other and are thoroughly
protected, at the same time being firmly held together by means of the lid a¹.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is;-
1. In collapsible boxes, the arrangement of lugs (i) on the sides (b & d) and
fastening irons (k) over the hollow sockets (h) of the other sides (a c) for main-
taining the sides (a b c d) in position by inserting the bars g into the sockets h,
substantially as hereinbefore described and shown in the accompanying drawings.
2. In collapsible boxes, the arrangement of attaching the halves () of the lid
or cover by means of hinges (i) on two opposite sides of the box and' of supports (m).
for receiving the halves of said lid or cover and bars (o) inserted through
openings (n q) and channels (p) in the sides, said bars being secured by means of
a seal, the halves of said lid being maintained in firm connection with those sides
of the box having the openings (n q) substantially as herein before described and
shown in the accompanying drawings.
3. In collapsible boxes, means for connecting the sides (a b c d) of the box
together, consisting of spring hooks (u w) mounted on the sides a c, said hooks
when the box is extended holding further hooks to mounted on the corresponding
sides bd, and the said hooks w in turn finding support on the edge (y) of the wall
of the plate, substantially as hereinbefore described and shown in the accom-
panying drawings.
4. In a collapsible box a modified form of lid fastening consisting of screws s¹
heing passed through the cover, which screws when the box is to be used, may be
firmly screwed in sockets b¹ fastened on the upper edges c¹ of the sides d', or when

page_text: the box is collapsed in sockets f¹ mounted on the encountering edges e¹ of the
sides d', which latter are capable of being folded inwards, substantially as herein-
before described and shown in the accompanying drawings.
