securing the key in place.
Fig. 8 shows a crate, the key or cover of which is locked in place by a pin passed
through a perforation in one of the end pieces and engaging the key.
A represents the bottom of the box; B, B' the ends; C, C, the sides, and F the
top or cover.
The side edges of the bottom are turned up to form vertical or perpendicular
flaps a, a, which bear against the outer surfaces of the sides C, C, respectively.
The lower edges of the ends B, B', are turned under and provided with perpen-
dicular flaps b, b, which engage and bear upon the outer surface of the bottom.
The side edges of the sides are bent to form perpendicular flaps 6, 6, which engage
and bear upon the outer surfaces of the ends.
The upper edge of the end B is provided with ears D, D, and the upper edge
of the end B' is provided with a tongue D', said ears and tongue being bent
inwardly over the box, as shown in Fig. 2.
E represents the key, which is in the form of a hollow square, or rectangular, the
end bars e, e, of which being horizontal, and the side bars e¹, e', of which being
vertical, as shown, whereby when in position upon the upper side of the box the
said side-bars engage and bear against the outer surfaces of the sides of the box,
and the end bars engage under the cars D, D, and tongue D' respectively.
The top or cover F is provided at its side edges with depending flaps f, f, which
engage and bear against the outer surface of the sides of the box, the end edges
thereof being adapted to be engaged by the ears and tongue above described.
It will be seen that the key holds the entire box in shape, and that if it is
removed by raising the tongue D' all the members of the structure will be
released.
Each member of the box is provided with two opposite upturned flaps or flanges,
which engage diametrically opposite sides of the box, the exception being in the
case of the ends which at one edge engage the bottom and at the other edge engage
the key.

page_text: It will be seen that no securing devices are needed in a box or crate constructed
in accordance with my invention.
Where made of strips, as a crate for vegetables, fruit, etc., the flaps or flanges
are formed by transverse strips attached to the edges of the members.
In Fig. 7 I have shown a slightly different manner of securing the key in place,
namely: G, G, are knobs or projections upon the upper surface of the key,
and H, H, are pivoted hooks to engage said knobs, the hooks being attached to one
of the ends of the crate and the opposite edge of the key being engaged by an ear
or tongue upon the opposite end piece.
Figure 8 illustrates still another manner of securing the key in place, namely, by
a pin K passed through a perforation in the upstanding edge of one of the end
pieces, the opposite edge of the key being engaged as in Fig. 7..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a box or crate of the class described, the combination with the opposite
end-sections, the side edges of which are inwardly bent, the bottom section having
its ends struck up to embrace the end-sections, and the side-sections having their
lower ends bent under the bottom, of the open locking frame having its opposite
ends downwardly bent to embrace the end-sections and its side edges embraced by
the upper bent edges of the side-sections, and the cover surmounting the locking
frame and covering the opening therein, said cover having its opposite ends
downwardly bent similar to and embracing those of the locking frame, and its
opposite side edges overlapped by the upper inwardly-bent edges of the side-
sections, substantially as specified.
2. A knock-down box comprising a bottom having upturned side edges, the side
edges having upturned end edges, the ends having upturned lower edges and
provided at their upper edges respectively with ears D, D, and tongue D', open key
frame E engaging said ears and tongue and provided with side flanges, and a cover
surmounting the key-frame, engaged by the ears D, D, and having its ends
embracing two of the opposite walls of the box, substantially as specified.
