The side walls I4 and side wall extensions I6
are provided with rearwardy extending flaps 26
and 28, respectively, and forwardly extending
iiaps 88 and 82, respectively. The above several
30 .
parts of the drawer are divided from each other
by longitudinal parallel scores 34, 38, 38, and
48, and by lateral parallel scores 42, 44, 46, and
48. The scores 84 and 88 divide the bottom I2 of
the drawer from the two side walls I4, while the
scores 88 and 48 divide the side walls I4 from
the side wall extensions I8. ‘I'he score 42 di

also divides the rearwardly extending ñaps 28
and 28 from the side walls I4 and side wall ex

the front wall 22 and forwardly extending flaps
88 and 32 from the bottom I2, side walls I4, and

48 separates the rear wall I8 from the rear wall 46
extension 28, while the score 48 separates the
front wall 22 from the front wall extension 24.
The flaps 28, 28, 88, and 22 are separated from
each other and from the front and back walls 22
and Il by knife cuts 88 and 52 and by narrow 60
slots 54 and Il along the longitudinal scores 34,
38, 28, and 48 extending inwardly to the lateral

To strengthen the bottom I2 of the drawer, I

25 score 48. The lower edges 84 oi' the arms BII are
spaced from the sc‘ore 44 a distance equal to the
height of the side walls I4, so that when the draw
er is folded, the reinforcing member 58 will aid
in supporting that portion of the front wall 22
30 which is above the side walls I4, and will also
serve to engage the tops of the flaps 89 and 82 and
secure them in proper position, as best shown in
Fig. 5. The stem 66 of the T shaped reinforcing
member 58 fits into reentrant right angles 88 and
35 19 formed in the front iiaps 39 and I2, thereby
distributing over a larger area the strain on the
naps caused by their attempting to move upward
1y. This stem 66 also serves to give added rigid
ity to that portion of the reinforcing member I8
40 which extends above the side walls I4 and sup
ports the top portion of the drawer front.
In erecting the drawer, the side walls I4 are
bent upwardly perpendicular to the bottom I2,
and the side wall extensions I6 turned inwardly
45 and downwardly against the side walls, so that
the side walls and side wall extensions together
form a double thickness wail for the drawer with
a smooth turned edge uppermost.> Next, the end
naps 28, 28, 30, and 32 are turned inwardly across
50 the ends of the drawer and enclosed within the
end walls I8 and 22 and end wail extensions 2l
and 24, which are folded in a manner similar to
the folding ofthe side walls and side wall exten
sions. In folding the iront wall and4 front wall
55 extension, care should be exercised to insure the
proper fitting of the reentrant angles B8 and 1I
around the stem 66 of the T shaped reinforcing
member 58.
When the drawer is folded, properly located
holes 12 in the iiaps are brought into alignment
with holes 'I4 in the end walls and end wail ex
tensions. In this position, screws 16 are inserted
through each set of aligned holes 12 and 'I4 and
secured by nuts 18. Because of the thickness of
the paper board, the portions of the end wall ex
tensions 29 and 24~which are folded inside the
drawer are provided with reentrant right angles

but differing somewhat especially in the' form
and arrangement of the reinforcement for the 25
drawer front, this being preferable where the
drawer is relatively shallow. In Figs. 9 to 13 the
primed reference characters are to be understood
as the same as or corresponding to the similarly
30
numbered parts in the previous characters.
In the form oi’ Figs. 9 to 13 I do not laterally in

extensions 8D’ and 32'. The reinforcing mem

filler of double thicknessinterposed between the
upper edges ci’ the extensions 28' and 82' and
the bight formed by the front wall 22' and its
return-folded extension 24’.
The reinforcing
member 58' is a narrow strip of a length twice the
width of the drawer. The ends of the member 88' 40
are folded inwardly so that they abut at the cen
ter. The mating faces of the main body and the
return-folded ends of the member 58' are glued
together. The reinforcing member 58' is then
glued to the inside face of the front wail 22' adja 45

in Figs. 11 and 13, as the front wall 22', carry 50

vertical position, the reinforcing member as
sumes a position immediately above the exten

of any hollows.

Although I have described a preferred embodi
ment of_my invention, it should be understood
that I contemplate that departures may be made
therefrom, and that the scope of my invention
is to be limited solely by the following claims.
I claim:

`
1. A file drawer comprising, a bottom wall; an
end wall and side walls attached to said bot
tom wall: an end wall extension and side wall
extensions attached to the end wall and side
walls respectively; said end wall being higher
than said side walls and having a member to
reinforce the portion of said end wall above said
side walls; and ñaps attached to said side walls
and side wall extensions, said flaps being in the
same plane as said reinforcing member and en
20 closed between the end wall and end wall ex
tension.
`
2. A ñle drawer comprising, a bottom wall; an
end wall and side walls attached to said bottom
wall: an end wall extension and side wall ex
tensions attached to the end wall and side walls
respectively; said end wall being higher than said
side walls and having a member to reinforce the
portion of said énd wall above said side walls;
i‘laps attached to said side walls and side wall ex
30 tensions, said iiaps being in the same plane as
said reinforcing member and enclosed between
the end wall and end wall extension;I and means
to reinforce the bottom of said drawer and hold
said side wall extensions against said side walls;
said means comprising a removable inner bottom.
3. A paper board ñle drawer comprising, a
bottom wall; an end wall and side walls attached
to said bottom wall, said end wall being higher
than said side walls; a reinforcing member for
40 said end wall, a portion of said reinforcing mem
ber substantially covering the inner surface of
said end wall above said side walls; another por
tion of said reinforcing member fractionally cov
ering the portion of said end wall below the tops
of said side walls; end wall and side wall exten
sions attached to said end and side walls; ilaps
attached to said side walls and side wall exten
sions, and adapted to be enclosed between said
end wall and end wall extension in the same
plane as said reinforcing member, and means to 10
reinforce the bottom of said drawer and hold said
side wall extensions against said side walls, said
means comprising a removable inner bottom.
4. A collapsed paper board filing drawer com
prising an integral blank having a central bot
tom wall, side walls extending laterally from the
side edges of the bottom, side wall extensions
extending laterally from the outer edges of the
side walls, ñaps extending from the front and
rear ends of the side walls and side wall ex 20
tensions, a rear wall extending from one end of
the bottom, a rear wall extension extending rear
wardly from the rear wall, a front wall of greater
height than the side walls and extending from
the other end of the bottom, and a front wall 25
extension extending forwardly from the front
wall, the flaps being of a length substantially
half the width of the bottom whereby, when the
side walls are swung to vertical position and
their extensions swung downwardly into contact 30
with the side walls and the flaps swung inwardly
to transverse vertical position, the ends of the
naps from the two sides substantially abut, and
a reinforcing strip of length approximating the
width of the front wall and adapted to fill the
space above the front flaps and between the
front wall and its extension when the drawer
is assembled.
