Improvements in the Manufacture of Trousers.
We JAMES DONALD of 7 Derby Street Greenheys, Manchester in the County of
Lancaster Tailor's Cutter and JOSEPH SIBLEY of Gresty Road Crewe in the County of
Chester, Manager do hereby declare the nature of this Invention to be as follows:-
Our said Invention relates to an improvement in the manufacture of trousers the
object of the said improvement being to do away with certain defects which at present
exist in ordinary trousers. For example when engaging in exercise and especially in
stooping and sitting down the position of the trousers on the legs of the wearer is
continually being altered or the trousers are subjected to severe strains as for example
at the knee or slack portions are produced in front the results generally speaking being
an ungraceful appearance and speedy deterioration of the garments. We have discovered
that the chief cause of these defects is the want of vertical elasticity in the waist of the
trousers at the back and the gist of our Invention is the introduction of suitable elastic
material into the waist of the trousers at the back so that when the body or the legs or
both are bent the back part of the trousers are stretched vertically allowing the legs of the
trousers to maintain their proper relative position on the legs and freeing the knees and
other parts from undue strains. In carrying our invention into effect we slit the waist
of the trousers behind and introduce into the slit and preferably behind the material of
the trousers a portion of elastic webbing securely sewn in position and capable

or bends his body the slit is extended and the elastic material yielding to the vertical
pull of the lower part of the garments and of the braces allows them to retain their
position and shape. On the wearer resuming his erect position the elastic material
returns to its normal unextended condition and the slit re-closes.
Instead of the
inserted piece of elastic webbing as set forth we might introduce strands of elastic
material or we might connect the edges of the slit by elastic laces or bands or we
might employ any other suitable means or material for conferring the requisite
elasticity upon the trousers.

Improvements in the Manufacture of Trousers.
We JAMES DONALD of 7 Derby Street Greenheys, Manchester in the County of
Lancaster Tailor's Cutter and JOSEPH SIBLEY of Gresty Road Crewe in the County
of Chester, Manager, 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 and accompanying drawings:
:-
Our said Invention relates to an improvement in the manufacture of trousers
the object of the said improvement being to do away with certain defects which
at present exist in ordinary trousers. For example when engaging in exercise and
especially in stooping and sitting down the position of the trousers on the legs of the
wearer is continually being altered or the trousers are subjected to severe strains as
for example at the knee or slack portions are produced in front, the results
generally speaking being an ungraceful appearance and speedy deterioration of the
garments. We have discovered that the chief cause of these defects is the want of
vertical elasticity in the waist of the trousers at the back and the gist of our invention

page_text: is the introduction of suitable elastic material into the waist of the trousers at the back
so that when the body or the legs or both are bent the back part of the trousers
are stretched vertically, allowing the legs of the trousers to maintain their proper
relative position on the legs and freeing the knees and other parts from undue
strains. In order that, our invention may be clearly understood we will now pro-
ceed more particularly to describe the same with reference to the annexed sheet
of drawings which illustrate the improvements.
Fig. 1 is a back view of a pair of trousers to which our invention is shown applied.
Fig. 2 is a sectional side view of the same.
Figs. 3 and 4 illustrate modifications of the invention.
Referring to Figs. 1 and 2 it will be seen that we slit the trousers at a above the
seat and beneath the waistband b. The lower edge of the slit a is connected by strips c
of elastic webbing to the waist band of the trousers or to any other suitably strong
portion of the trousers above the slit. In the drawing we have shown six such
elastic strips c but any greater or less number may be used. To prevent the slit a
from opening too widely at the centre we connect the upper edge of the slit to the
seat of the trousers by means of an elastic strip d, or the edges of the slit may
simply be connected at the centre by a piece of elastic material. In Fig. 2 the
slit a appears and the dotted line c represents the position of the elastic strips c.
The said elastic strips or connections are of course placed on the inner side of the back
of the trousers so that normally they remain entirely concealed. When the wearer
stoops or bends his body or legs, the slit a opens or is extended, yielding to the
drag on the lower portions of the trousers. The elastic strips c and stretch to
the pull of the lower portion of the garments or braces and the trousers retain
their proper position, shape and appearance on the legs of the wearer, instead of
being subjected to the distortion and injurious strains which ordinary trousers
suffer from their want of elasticity and which result in wrinkles and bagging at the
knees. On the wearer resuming his erect position the elastic strips return to their
normal unextended condition and the slit a becomes again closed.
The position and shape of the slit a may vary from that shown in the drawings.
Figs. 3 and 4. illustrate obvious modifications in our invention. Instead of the elastic
strips as in the foregoing figs, we may employ a continuous piece of elastic
webbing e as shown in Fig. 3 which connects the under edge of the slit a, or an
extension thereof, to the waist band b. In Fig. 4 the edges of the slit a are connected
by means of lacings which may either be themselves elastic or have their ends
attached to elastic terminations. We do not however limit ourselves to the illustrated
modes of obtaining the requisite elasticity as further_modifications in the practical
application of our invention might be easily devised. For example instead of merely
slitting the trousers a portion of the back might be entirely removed and replaced by
a portion of elastic webbing preferably of the same appearance or texture as the cloth
of the trousers.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
(1) In the manufacture of trousers the introduction or application of elastic
material at the back of the trousers and between the waistband and the seat so as to
allow the same to yield readily to the movements of the wearer substantially as
described and shown.
(2) In the manufacture of trousers slitting or dividing the material of the trousers
or removing a portion thereof at the back and between the seat and the waist band
and introducing or inserting a piece or pieces or strips of elastic webbing or material
at the said back portion of the trousers in the manner set forth so as to allow the back
part of the trousers to yield easily when the wearer stoops or bends his body or legs,
and to resile to its normal position when the wearer stands erect, for the purposes and
substantially as described and shown.

page_text: (3) In the manufacture of trousers introducing elastic material into the back part
of the trousers between the seat and the waist band for the purposes and substantially
as hereinbefore described and as illustrated in the accompanying drawings.
