CHARLES HENRY STANBURY of No 91 Fleet Street in the City of London
"IMPROVEMENTS IN BOXES OR TRUNKS,"
This Invention has for its object improvements in boxes or trunks.
I make boxes or trunks telescopic that is to say the upper part carrying the lid
is separate from the lower part and these two parts slide the one within the other.
The upper part fits within the lower and has flaps attached to the lower edges of
two of its sides. These flaps are formed of several strips hinged together, the strips
being of the same thickness as the sides of the upper part of the box. When it is
desired to increase the capacity of the box, the upper portion is drawn up and one
or more of the strips are turned down so as to form continuations of the sides of
the upper part of the box the lower ends abutting firmly against the bottom.
Straps or other fastenings are arranged to connect the upper and lower portions of
the box and so prevent the upper portion being drawn further out whilst the flaps
prevent it from being pushed in again. In this way the box can be made of several
sizes according to the number of strips in the flaps. The strips when not in use
are strapped or folded back out of the way.
The upper part of the box might be arranged outside the lower part and the
flaps might be on the upper edges of the sides of the lower part but I consider the
first described arrangement to be the most convenient.
.
The trays which tit inside ladies travelling boxes may also be constructed in a
similar way so that when the box is enlarged the trays may be enlarged also.
The above described method of supporting the upper part of telescopic boxes has
the advantage of giving great stiffness to the box when enlarged.

"IMPROVEMENTS IN BOXES OR TRUNKS
"
This invention has for its object improvements in boxes or trunks.
I make boxes or trunks telescopic that is to say the upper part carrying the lid
is separate from the lower part and these two parts slide the one within the other.
The upper part fits within the lower and has flaps attached to the lower edges
of two of its sides. These flaps are formed of strips hinged together, the strips
being of the same thickness as the sides of the upper part of the box. When it is
desired to increase the capacity of the box, the upper portion is drawn up and one
or more of the strips are turned down so as to form continuations of the sides of
the upper part of the box the lower ends abutting firmly against the bottom.
Straps or other fastenings are arranged to connect the upper and lower portions of
the box and so prevent the upper portion being drawn further out whilst the flaps
prevent it from being pushed in again. In this way the box can be made of several
sizes according to the number of strips in the flaps. The strips when not in use
are strapped or folded back out of the way.
The upper part of the box might be arranged outside the lower part and the flaps
might be on the upper edges of the sides of the lower part but I consider the first
described arrangement to be the most convenient.
The trays which fit inside Ladies travelling boxes may also be constructed in a
similar way so that when the box is enlarged the trays may be enlarged also.
The above described method of supporting the upper part of telescopic boxes has
the advantage of giving great stiffness to the box when enlarged.
The drawings hereunto annexed shew a box or trunk constructed in the manner
I prefer for carrying out my invention.
Figure 1 is a longitudinal vertical section and Figure 2 a transverse section of
the box. Figures 3 and 4 are similar views shewing how the capacity of the box
can be increased by drawing upwards the upper part of the box.
A is the lower part of the box, B the upper part sliding within it and fitted at
the top with a lid C. D D are the flaps hinged to the lower edge of the two ends
of the part B-preferably the hinge joints are formed by securing the strips D to a
canvas lining which is also secured to the inside of the part B. E are short straps
fixed to the bottom of the part A and each carrying a buckle. Fare straps secured
to the interior of the part B-when these straps are secured in the buckles they
hold down the upper part B into the part A and prevent its being drawn out.
In Figures 1 and 2 the strips D are shewn turned upwards and held against the
ends of the part B by the straps E F. When it is required to enlarge the capacity
of the box the straps E F are unbuckled and the upper part B is drawn upwards.
Small canvas straps G secured at their ends to the parts A and B respectively
prevent the part B from being then entirely withdrawn from the part A. Both
strips D at both ends of the part B may now be turned down into the position
shewn on the left hand side of Figure 3 and the straps E F be again buckled
together to securely hold down the part B and keep the lower edge of the bottom
strip D abutting against the bottom of the box. On the right hand side of Figure 3
the straps E F are shewn unbuckled and the strips D not pressed back against the
end of the part A so as to show more clearly the way in which the several parts
are formed. When it is not required to enlarge the box to its full capacity then

page_text: the upper strip D only might be turned down so as to lie against the ends of the
part A, whilst the lower strips would be turned upwards as in Figures 1 and 2.
In place of two strips only being jointed to the lower edge of each end of the
upper part B of the box a single strip or a greater number of strips might be sɔ
jointed to it.
Having thus described the nature of my Invention and the manner of performing
the same I would have it understood that I do not claim generally the making of
telescopic boxes or trunks but I claim the combination with such boxes of flaps D
and retaining straps E F substantially as described.
In witness whereof I the said Charles Henry Stanbury have hereunto set
my hand and seal this fifth day of March in the year of our Lord One
thousand eight hundred and eighty three.
