The invention consists in the several novel fea
tures of construction hereinafter set forth and
more particularly defined by claims at the con.
clusion hereof.
In the drawing: Fig, 1 is al perspective of one
form of brief-case embodying the invention, a
corner of the outer cover of leather being folded

Fig. 4 is a section on line 4-4 of‘Fig. 3. Fig.
5 is a section on line 5-5 of -Fig. 3l.
In Figs 1 and 2, the invention is applied. to a
brief-case which comprises sides -I connected to
gether by a fold to form the back 3 anda strip
‘ 9 of flexible material, such as stout thin woven
30 cloth, along the inner and top edges of the sides
'I, which permit expansion. of the sides and are
adapted to be secured together by hookless fas*
secure the backingsheet, the facing or liner
sheet, and the binding strip- 9 together. A sheet 10
of leather I5 is cut to conform to the shape of
the case desired to form the outer cover for the
sides. 1 and back 8. The edge of this sheet is
finished by suitable tools so that it will be smooth
and possess a finished appearance.
The inner l
structure comprising strip 9, sheets I2 and ||
which have been bound together by the seam I4
and binding strip I3 are placed on the leather
cover sheet I5 which is then seWed to» the inner
structure by a seam I 6 which extends through 20
the cover sheet I5, sheets II and I2, strip 9 and
both of the sides I3b and I3c of the binding strip
I3. The seam I6 is made outwardly from the
seam I4 so that the outside of seam I4 Will be
covered by the leather sheet f I5 and only the
seam I6 will be visible when the case is closed.
The finished edge I5a of sheet I5 terminates
substantially in or near the plane of the outer
portion I3a of .the binding strip I3. The ñnished
edge I5a of the leather cover sheet I5, the binding
strip I3, and the seam I6 are visible from the
teners IIl for closing and opening the case. In
this type of case, the sides 1, when the case is

In building up the case, a sheet I I of somewhat
stout and diu‘able because the inner seam. binds
flexible backing or stiffening material such, for
example, as cardboard or strawboard, and a
sheet I2 ofA material for forming an inner lining
40 or fastening, are cut into shape to conform to
the sides -I and back 8 of the case. Sheet I2 may
be of thin leather or ñne cloth which is adapted
to serve as a ñnish for the inside of the case
and to protect the contents from contact with
the stiffening sheet Il. 'I‘he stripI 9 is- then laid
with its outer edge so it conforms to the margin.
of the stiffener sheet II and liner sheet I2. A
binding strip |3 preferably of leather and of
suiñcient width to extend around the edges of
sheets II, I2 and strip 9 and to lap the outer
faces of sheet || and the inner face of strip 9,
is extended as at I3a around the edges of said
sheets and strip and folded to lap and fit against
55 the entire margin of the outer'face of strip 9, as
This construction provides a margin which is
the binding strip, the backing and liner strips
and the expansible strip together, and the outer
seam secures together the same parts and the
leather cover sheet.
The margin of the brief-case presents an at
tractive and ñnished appearance on account of
leaving visible the cut edge of the leather on the
outer cover, the single seam on the outer face
of the cover, and the folded edge of the binding. 45
In Figs. 3 and 4, the brief case comprises a
front side I8, a back side I9, with a construction
2| forming a ñap to extend over and close the
top of the case, and pockets in the case and be
tween the sides which are formed by partitions 50
23 which are connected to one another and to
the sides by an expansible or bellows memberV 24
of leather, which extends along the ends and
bottom of the case.
The front side I8 comprises an outer or cover- `55
sheet of leather 26 and an inner facing or liner
21 of thin material, such as iine fabric or leather.
Thelback-side I9 and the flap 2I comprise a
cover-sheet 26’ of leather and a liner 21' of
ñne fabric or leather. Bellows-member 24 is
looped around the edges of partitions 23 and
sewed thereto as at 23C. The outermost strip
' 24a of member 24 is extended tolap the margins
comprising a strip having its margin lapping the
margin of the inner face of the liner, and a
binding striprfolded around the edges and lap

strips 24a, respectively, are stitched- together by gether by a connecting back at one margin, a
a seam 32 which extends through the liner and
connecting strip between the sides, the sides com
strip 24a and both portions 28S”V ofthe binding prising an outer sheet of leather, an inner lining
strip adjacent the inner edge of theV latter.
The leather cover-sheet 26 is cut Yto fit the
20 side I8 and the cover-sheet 26’ is cut to lit >side
I9 with its flap 2|. 'I'he edges of the leather
sheets 26, 26’ are finished off and correspond
substantially toV the outer edge of the binding
strips. The outer ycover-sheets. of leather are
each secured to the Vpreviously formed structure
composed of the liner strips 21, the member
24 and the binding strips 28 by seams 30, which
are stitchedrthrough' the lapped margins of the
cover sheets, the binding sheets, and strips 24a,
30 respectively. This edge-construction is strong
and durable because the liner-sheet, expansible
member, and binding~strip are united together by
the inner seam and are also united together and
to the outer cover by the outer seam. The fin
ished edge is attractive in appearance, the single
outer seam, ñnished edge of the leather, and the
edge of the binding strip being visible, while the
inner seam is invisible from the outer sides of

the case.
The invention is not to be understood as re
stricted to the details set forth, since these may
be modified within the scope of the appended
of thinY flexible material and a stifîening sheet
between the liner andthe covering sheet, the
connecting strip having its margin lapping the
margin of the liner sheet, a binding strip folded
around the edges and the sides of the backing
and liner sheets and the connecting strip, the
binding strip, the liner and the connecting strip
being stitched together by a seam spaced from ‘
their edges and passing through them, the outer

between the sides, the sides comprising an outer
covering sheet of leather and an inner. liner of
relatively thin ñexible material, the connection
stitched together by a seam spaced from the 45

sheet having its edge conforming to the binding
strip and stitched thereto by a seam extending
through both folds of the binding strip, the liner
and backing sheets and the connecting strip out- '
