PROVISIONAL SPECIFICATION.
Improvements in the Construction of Spherical, Elliptical, and
similarly shaped Collapsing Boxes.
I, FRANCIS JAMES CANDY, of Highfield, Fen Ditton, in the County of Cambridge,
Master of Arts, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of spherical, elliptical, and similarly shaped
collapsing boxes the object of the invention being to produce a strong and substantial
form of box of this character which can be used for various useful purposes.
The boxes may be made of metal, wood, cardboard, millboard, papier-maché, or of
any other material or composition of materials which is sufficiently rigid to maintain
its shape. They are made in three or more sections one of which is rather larger than
the others, and is provided with a boss at each extremity carrying pivot pins, on to
which are pivoted the ends of the other sections. All the sections turn on the said
pivot pins which form the ends of an imaginary axis to the spherical elliptical, or other
similarly shaped figure.
The sections are so placed on the pivot pins that they can all be nested in the largest
section, and the end sections are provided with flanges which can be bolted or other-
wise fastened together when the box is in use. Each section is provided with a bead
or rim which abuts against a shoulder or the like on the next section, so that the
pulling forward of the end section pulls forward the other sections.

COMPLETE SPECIFICATION.
Improvements in the Construction of Spherical, Elliptical, and
similarly shaped Collapsing Boxes.
I, FRANCIS JAMES CANDY, of Highfield, Fen Ditton, in the County of Cambridge,
Master of Arts, 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 relates to the construction of spherical, elliptical, and similarly shaped
collapsing boxes, the object of the invention being to produce a strong and substantial
form of box of this character which can be used for various useful purposes.
The boxes may be made of metal, wood, cardboard, millboard, papier-maché, or of
any other material or composition of materials which is sufficiently rigid to maintain
its shape. They are made in three or more sections one of which is rather larger than
the others, and is provided with a boss at each extremity carrying pivot pins, on to
which are pivoted the ends of the other sections. All the sections turn on the said
pivot pins which form the ends of an imaginary axis to the spherical, elliptical or other
similarly shaped figure. The sections are so placed on the pivot pins that they can all
be nested in the largest section, and the end sections are provided with flanges which
can be bolted or otherwise fastened together when the box is in use. Each section is
provided with a bead or rim which abuts against a shoulder or the like on the next
section, so that the pulling forward of the end section pulls forward the other sections.
And in order that my invention may be wore fully understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawings, in which similar letters are used to indicate corresponding parts throughout.

page_text: Figure 1 is a side elevation, and Figure 2 an end elevation of a cylindrical collapsing
box constructed in accordance with my invention ;
Figure 3 is section on the line a b at Figure 1 ;
Figure shews an end elevation of the same box partially closed and Figure 5
shews it entirely closed.
Figure 5 is a section on c d Figure 5.
Figures 6 to 12 shew other forms of my invention which will be explained here-
after.
Referring to Figures 1 to 5ª, all the parts A are made in the shape of a sector or
triangular section of the cylinder slightly varying in size, so that they will nest one in
the other, the largest A¹ being provided at each end with a boss B through which
passes a pin C on to which the ends of all the other sections are pivoted, (see Figure 5*).
Each section is provided with a bead or rim D on one edge and with a shoulder or the
like E on the other edge, so that the bead or rim D on one section, abuts against the
shoulder or the like E on the contiguous section, as shewn in Figure 3, thereby
preventing the sections from separating from each other when pulled out and also
opening out all the sections one after the other by simply pulling out the end sections A².
The largest section A' is provided with a shoulder or the like E at each end, and the
end sections A² have a bead or rim D at one end, and a flange F at the other. These
two flanges F lie against each other when the box is fully opened as in Figures 1 and 2,
and are secured by bolts, or by a catch piece G pivoted to one of them, as shewn
in Figures 1 and 2, or they may be secured in any other convenient manner.
beads or rims D and the shoulders or the like E may be on the longitudinal edges of
the sections as shewn in Figure 3, or they may be on the edges at the ends of the
sections, or on both as found desirable. In collapsing or opening out the box, all the
sections will turn on the pivot pins C which being aligned form the ends of an
imaginary axis to the box as previously stated.
The
In Figures 6 and 7 I have shewn side and end elevations of a conico-cylindrical
form of collapsing box. The construction and mode of operation is the same as in the
cylindrical form already described, except that in this case the ends of the sections
form parts of a cone, and the boss B is in the shape of the apex of a cone..
Figure 12 shews another simple form of fastening adaptable to the cylindrical or
conico-cylindrical forms of box shewn in Figures 1 and 6. The flanges F' are made
tubular and a bent wire G₁ is passed through from one end, or a short bent wire G¹ is
used, placed in each end to hold the two flanges together.
Figures 8 and 9 shew two elevations, taken at right angles to each other, of a
spherical collapsing box. Figures 10 and 11 shew one of my collapsing boxes applied
as trigger and hammer guard to a sporting or other gun.-The-largest-section_is_fast_
on the stock at the side of the ordinary trigger guard, and all the other sections may
be pulled out and fastened in position so as to completely encircle. the trigger and
hammer and prevent the gun from being accidentally exploded when pulling it through
bushes or such like. Figure 10 shews a side elevation of the gun with the box
collapsed and Figure 11 shews an end elevation of the gun with the box in section
opened out and encircling the trigger and hammer. It will be understood that this
application of my invention may be also used simply as a trigger guard for hammerless
guns and rifles, and that it will effectually prevent the accidental discharge of the gun
or rifle, which at full cock, might be poked or pulled through a bush or hedge with
impunity. For firing, the catch at top is released and the sides or sections of the box
fall down leaving the trigger exposed as required.
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 :-
A collapsing box consisting of three or more sections, pivoted together and nesting
one within the other, the sections having beads or rims and shoulders or the like to
cause the sections to open each other out one after the other and to keep them together

page_text: when opened out, the box being secured by a catch, bolts, or other suitable means,
constructed and operating substantially in the manner described and illustrated, and
for the purpose stated.
