COMPLETE SPECIFICATION.
Improvements in Means for Opening and Displaying the Contents of
Boxes, Cases, Cabinets, and the like.
I, HENRY WIGFULL, Silversmith, of John Street Works, Sheffield in the
County of York 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 has for its object to so construct boxes, cases, cabinets and the
like that the act of opening them serves to project the contents forward to display
them prominently to view and consists in hinging the sides at their bottom parts
and connecting thereto levers passing under the bottom of the receptacle, and
which on opening the said sides automatically raise the bottom and with it the
enclosed contents.
In the accompanying sheet of illustrative drawings :
Fig. 1 is a perspective view of a box constructed according to this invention, the
hinged sides being fully open and the bottom raised to display the articles contained
in it.
Fig. 2 is a similar view with the sides partially closed and
Fig. 3 is a view of the sides and bottom when fully opened the ends being entirely
removed.

C
A movable bottom a having end projections 6 sliding in vertical guides c secured
to the ends d of the box, rests upon bent levers e secured to the sloping sides which
are hinged at their bottom parts to the bottom or base frame
9.
On opening the box the sides f and with them the levers e are rotated about the
hinge axis and raise the bottom a as seen in Fig. 2 until the sides are fully opened
when the bottom is raised into the position shown in Fig. 1. thereby displaying the
contents of the box prominently to view.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In boxes, cases, cabinets and the like supporting the bottom on levers secured
or connected to the sides so that the act of opening them automatically raises the
bottom and displays the contents substantially as described.

page_text: 2. The combination of the movable bottom a and guides c with levers e secured
to hinged sides f substantially as described.
3. The arrangement and construction of boxes, cases, cabinets and the like
substantially as described with reference to the drawings.
