1 Claim.
This invention relates to garments, and par
ticularly to a sleeve structure including an ex
panding insert, the object being to provide a
construction of sleeve which will be conventional
5 in appearance but which at the elbow or other
desired points will be expansible to take care of
any unusual strains.
Another object of the invention is to provide
an expansion insert for sleeve wherein the parts
10 are so formed that when any strain or tension
thereon is released the parts will spring back
into their normal position.
In the accompanying drawing:
Fig. 1 is a perspective view showing a ?gure
with a garment embodying the invention ?tted
Fig. 2 is an enlarged fragmentary side view of
one of the sleeves shown in Fig. 1;
Fig. 3 is a view similar to Fig. 2 but showing
20 only the sleeve without the cuff or the insert;
Fig. 4 is an elevation of the insert shown in
Fig. 2;
Fig. 5 is an enlarged fragmentary sectional
View through Fig. 2 on the line 5—5;
Fig. 6 is a fragmentary sectional view through
Fig. 2 approximately on the line 6—6, the same
being on an enlarged scale;
Fig. '7 is a fragmentary view showing part of a
sleeve with dot and dash lines indicating how an
30 expansion member may be formed intergral with
the sleeve;
Fig. 8 is the next step from Fig. 7 in forming
the joint.
Referring to the accompanying drawing by nu
35 merals, I indicates a shirt which may be of any
desired kind. The shirt I is provided with sleeves
2, and 3 which are identical except that they are
for right and left arms. These sleeves are made
in the conventional way and are each provided
40 with a conventional cuff 4. However, they are
of special construction by reason of the expan
sion insert or panel 5. The blank of this in
sert is shown in Fig. 4, from which it will be seen
that the insert is formed with parallel side edges
45 6 and 1 and a. tapering end B. When the insert
is mounted in blank 5, edge 6 for instance is
stitched to the sleeve 2 along the edge 9 of the
insert opening [0. Edge 1 is stitched to the sleeve
along the edge ll of the sleeve and the two edges
12 and I3 are stitched together so that the ?n
ished structure will appear as indicated in Fig. 2.
However, after the blank 5 has been stitched in
place it is folded along a central line and then
the cuff 4 is placed in position, after which the
55 lines of stitching M are applied. This stitching
will secure the side edges 6 and ‘I together at
the end I5.
After the insert has been inserted and the cuff
l4 applied the parts will appear as shown in Fig.
80 2. with the insert 5 folded along the central line
(Cl. 2-125)
[6 as indicated in Fig. 5. Normally the opening
I0 will remain substantially closed as shown in
Figs. 2 and 5, but in case the arms are swung to
the position shown in Fig. 1 or some other posi
tion whereby tension is brought to bear on the
sleeve, the edges 9 and II‘ will separate as indi- '
cated in Fig. 1 and the expansion insert 5 will
gradually unfold until the parts appear for in
stance as shown in Fig. 1. It will be noted from
Fig. 1 that by reason of the position of the in 1O
sert it is in what may be termed the outside part
of the sleeve whereby it readily expands when
the elbow is bent.
As soon as the tension is
released the parts will automatically return to
their former position. 'The threads 14 stitching 15
the edges 6 and 1 together at end 5 will produce
an action causing the opening ID to automati
cally close.
Instead of applying a separate insert or panel
as just described, an insert or triangular expan 20
sible panel 5' might be provided from the body
of the material of sleeve 2. As shown in Fig. '7
the sleeve 2 is made slightly of greater diameter
and is folded along the lines I‘! and [8 until the
parts appear as shown in Fig. 8. The corner I9 25
is then pulled longitudinally of line 20 until the
respective wide edges 2! and 22 are parallel with
the edge 23 whereupon the stitching [4 could be
applied. This gives what may be termed an in
tegral insert or panel which will allow a certain 30
expansion of the sleeve when the elbow of a per
son Wearing the shirt is bent, although normally
the sleeve will remain flap or undistended. As
the insert or panel 5' is integral it must taper
as shown in Fig. 8, but will readily expand when 35
the elbow is bent by reason of its position on
what may be termed the outside part of a sleeve.
Where it is a separate piece it may be arranged
as shown in Figs. 2, 4 and 5, which will permit
a greater expansion at or adjacent the elbow.
I claim:
A shirt provided with a full length sleeve having
a cuff with an opening and means for disen
gageably holding the cuff closed, said sleeve be
ing formed with a fullness from adjacent the 45
elbow to the cuff end, said fullness being formed
as a single triangular expansible panel normally
lying ?at and extending from adjacent the elbow
to the cuff with the point adjacent the elbow of
the sleeve and the wide end at the cuff, said panel 50
being part of the outside part of the sleeve so
that as the arm of a person using the shirt bends
at the elbow the panel will expand approximately
from the elbow to the cuff and then move back
to a flat position when the arm is straightened,
said wide end of said panel being positioned par
allel with the edge of said cuff and a seam con
necting the cuff to the sleeve and said wide end
to the cuff in permanent folded position.
