mprovements in Sandals and in the Material for their Manufacture.
I, EUGENE BALLY, of Aarau, Canton Aargau, in the Republic of Switzerland,
Manufacturer of Elastic Goods, do hereby declare the nature of this invention and
a what manner the same is to be performed, to be particularly described and
scertained in and by the following statement :-
Sandals as at present in use have the disadvantage of not fitting sufficiently close
on the upper part of the foot, in consequence of which they are very liable to
lip off.
In order to overcome this objection I make the upper part of the sandal of elastic
abric whereby it adapts itself to and closely fits the fore part of the foot and thus
nsures a firm hold of the sandal to the foot.
The elastic fabric, which I employ in the manufacture of such sandals, may be
plain or variously coloured and ornamented or not with patterns according to taste,
but it is preferably adorned with threads of gold, silver, or other metal, the threads
being either woven into the fabric or put in by sewing. This ornamentation of the
elastic fabric is preferably effected as follows:-The metallic threads are loosely
woven into the woollen back of the elastic fabric as warp-threads, that is to say,
they are woven with much less tension than the other warp-threads, so that these
metallic threads make visible loops or curls on the upper surface of the right side.
The improved sandals having their upper part of elastic fabric, may be made with
or without heels.
In the accompanying drawings :-
Figure 1 is a plan of a sandal without a heel made according to my invention,
the elastic fabric being single coloured and ornamented with metallic threads.
Figure 2 is a transverse section on the line 2-2 of Figure 1.
Figure 3 is a similar view to Figure 1 but shewing a sandal with a heel, and the
elastic fabric inade of various colours, with in-woven metallic threads.
Figure 4 is a plan of the right side of the elastic fabric ornamented with metal
warp-threads, and,
Figure 5 is a section of the same.
The elastic fabric shewn in Figures 4 and 5 consists, like ordinary elastic fabric,
of a cotton warp which shews upon the wrong side of the fabric, of one or more
(according to the design of the fabric) woollen, warp threads, also shewing upon the
wrong side, of an india rubber warp which lies between the two previously mentioned
warps and of one or more weft threads, which secure the various threads of the
warp together, and it further consists, unlike the ordinary elastic fabric, of the warp
of metallic thread with which I effect the ornamentation of the right side of the
material.
In Figures 4 and 5 a, a are the cotton warp threads b, b the woollen warp threads;
c, c the india-rubber warp threads; d, d the metallic warp threads, and e, e the weft
thread or threads.
The metal warp threads d (such as gold, silver or copper threads) are not stretched
tightly, but are quite loose, and are woven into the fabric alongside the woollen
threads, that is to say, the threads d are at a much less tension in the loom than the
other threads and are only held by a few threads of the weft e, so that these
metallic threads pucker up on the right side of the fabric, and appear as loops or
curls, which contribute to the ornamentation of the elastic fabric, whilst on the
other hand the threads d by reason of their looseness, do not detract in the least
degree from the elastic qualities of the fabric.
The upper part A of the sandals, Figures 1 and 2, consists of an elastic fabric
such as that described with its ornamentation of metallic threads, or of any other

page_text: elastic fabric single-coloured or of various colours and plain or having a pattern
and is firmly held at its lower edge between the sole B and the inner sole (or welt) C
the two latter being as usual made of leather and connected in the ordinary way
The edge which remains free is bound with a border D which is sewn on. The
dotted lines, a, b, in Figure 1 represent the metal threads which are very loosely
woven as warp threads into the elastic fabric, and these serve for the ornamentation
of the single coloured fabric, and form ou the woollen upper side of the latter loops
or curls which project but very slightly.
The sandal shewn in Figure 3 is the same as that shewn in Figures 1 and 2
except that it is provided with a heel E, and that its upper part A consists of elastic
fabric with variously coloured stripes in wool on the right side.
The stripes of various colours in Figure 3 are produced by intersections of
different kinds.
The improved sandals, having their upper parts made of elastic fabric possess the
further advantages that the foot, as the result of the elasticity of the material
employed, is able to move with much greater freedom and is free from any pressure
or confinement, and more particularly that the evaporation from the feet is much
easier and freer than in the sandals hitherto used, which are usually made of cloth
or satin, and heavily ornamented with gold or silver needlework. My sandals
having their upper part made of elastic fabric are also much more durable than
those at present in use.
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 :-
1. Sandals, the upper part of which is made of elastic material, of one or several
colours, and either plain or ornamented, the elastic fabric being secured to the sole
of the sandals and allowing a better adaptation of the sandals to the feet and a
freer movement of the foot and facilitating evaporation from the foot and increasing
the durability of the sandals, substantially as hereinbefore described.
2. Sandals having their upper part of elastic fabric ornamented with metallic
threads such as gold, silver or copper threads, substantially as hereinbefore
described.
3. As a new article of manufacture, an elastic fabric specially suited for the
manufacture of sandals, and having its right side ornamented with metallic threads
such as threads of gold, silver or copper woven in as warp threads by the side of
the woollen threads which form the right side of the fabric and puckered up on the
right side of the fabric so as to be visible thereon in the form of slightly projecting
loops or curls.
