Improvements in Paper Boxes.
1, ROBERT PITFIELD BROWN, of 3412 North Nineteenth Street, in the City
of Philadelphia, in the State of Pennsylvania, one of the United States of America,
Manufacturer, do hereby declare the nature of my invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention relates to knock down paper or card board boxes, and has for its
main object to provide a box which may be very easily set up and when set up
will be very firm and stiff.
My invention is best understood as explained in connection with the accompanying
drawings, in which,
Fig. 1 is a view of the blank from which I construct my preferred form of box.
Fig. 2 is a view of a box, formed from the blank shown in Fig. 1, showing the
box partly set up and with a portion of the side torn away so as to show the end.
Fig. 3 is a vertical section illustrating a modified form of box.
Fig. 4 is an end view in section, on an enlarged scale illustrating a slight modifi-
cation of the box shown in Fig. 2, and
Fig. 5 is a perspective view of a box completely set up and in position to be
pushed into a telescope cover.

A is the blank from which I construct my box and consists, as shown in Fig. 1,
of a bottom B, sides S S and ends E E. The sides I provide with wings
extending from each extremity thereof, as shown in Figures 1 and 2; these
wings, when the box is set up, as shown in Fig. 2, are adapted to form parts of
the ends of the box. The ends consist of flaps e e which are adapted to fold
outside of the wings ss and of flaps e¹ e' which are adapted to fold inside the
wings ss. In the construction shown in Fig. 1, I provide these flaps ele' with
wings E' E' which project from their sides substantially as shown; these wings E¹ E¹
fold against the sides S S of the box, as shown in Fig. 2. I also preferably provide
additional flaps e e², which fold against the bottom of the box and serve to further
secure the ends and hold them in place. I also may in some cases provide additional
locks bb for the ends of the box, which locks may consist, as shown in Fig. 2, of a
strip of card board B¹ whose ends abut against the end flaps el e¹ and hold them in
position, or fold over the flaps e if these are employed, or I may form the locks by
cutting tongues in the material of the bottom of the box. The pieces B¹ if used
may be broad enough to form a false bottom, or may be simply a narrow strip, and,
in the latter case, I prefer to secure it to the bottom of the box, as by pasting. It
will be noted that when a piece of card board is employed, it not only serves as a
lock but also stiffens the box.
I may dispense with the wings E' and construct the box, as shown in Fig 3,
where the strip or piece B' is alone employed to hold the ends in position, but
unless very stiff material is used I find that the flaps e will bulge, as indicated in

page_text: dotted lines at f, Figure 3, the action of the wings
that of a brace or strut, and
as they make a right angle with the flap e' at the bend e³ they serve to keep this
flap very neatly in position. In most cases I prefer, however, to dispense entirely
with the additional locks and depend entirely on the wings E E¹ or these
wings and the flaps e² e² to hold the ends in position; these Haps e e² as I have
indicated, may however, if it is found desirable, be dispensed with, as shown in
Fig. 4.
A box constructed from a blank similar to that shown in Fig. 1, will be found
very stiff, as the ends are formed of three thicknesses of material, and very easy to
set up since there are no locks to be engaged, and in practice the ends have been
found to be firmly held by the wings E E which are crowded against the sides of
the box, without any additional locks; such a box is shown in Fig. 5. Any sort of
cover, may, of course, be provided, either a cover formed in the same way, or a
telescope cover, as indicated at C, Figure 5.
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
e
1. A knock down box having a bottom B, sides S provided with wings & $
extending from both extremities of said sides and adapted to form part of the
ends of the box, and end pieces E consisting of flaps adapted, when the box
is set up, to fold outside of the wings ss, flaps el el adapted to fold inside of the
wings ss, and wings E' E' projecting from each side of the flaps e¹ e and adapted
to fold against the sides S S of the box, substantially as shown.
2. A knock down box having a bottom B, sides S provided with wings 3
extending from both extremities of said sides and adapted to form part of the
ends of the box, and end pieces E consisting of flaps e e adapted, when the box
is set up, to fold outside of the wings ss, flaps el el adapted to fold inside of the
wings, wings El El projecting from each side of the flaps e¹ el and adapted to
fold against the sides S S of the box, substantially as shown, and flaps e² e² adapted
to fold against the bottom of the box.
3. A knock down box having a bottom, B, sides S provided with wings & s
extending from both extremities of said sides and adapted to form part of the
ends of the box, end pieces E consisting of flaps ee adapted, when the box is
set up, to fold outside of the wings ss, flaps el el adapted to fold inside of the
wings ss, and wings E¹ El projecting from each side of the flaps e'e' and adapted
to fold against the sides S S of the box, substantially as shown, and locks b
adapted to hold the flaps e¹ el in place.
4. A knock down box having a bottom B, sides S provided with wings s s
extending from both extremities of said sides and adapted to form part of the
ends of the box, end pieces E consisting of flaps e e adapted, when the box is
set up, to fold outside of the wings ss, flaps e adapted to fold inside of the
wings ss, wings E' E' projecting from each side of the flaps e e¹ and adapted to
fold against the sides S S of the box, substantially as shown, and flaps e e
adapted to fold against the bottom of the box, and locks bb adapted to project
over the flaps e²e and hold the ends in place.
5. A knock down box having a bottom B, sides S provided with wings
extending from both extremities of said sides and adapted to form part of the
ends of the box, end pieces E consisting of flaps e e adapted, when the box is set
up, to fold outside of the wings as, flaps el e' adapted to fold inside of the wings s
and a piece of card board B' whose ends form locks bb adapted to hold the ends in
place.
