Improvements in India Rubber Bands or Rings.
LOUIS NISSIM, Mechanist, 12, Leadenhall Street, Loudon, E.C., do hereby declare
the nature of this invention to be as follows:--
-
My invention relates to india rubber bands, hoops and rings. The object of
my invention is to make these articles of greater strength than hitherto, the same
thickness of rubber only being provided as before, that is to say, if from a
sheet of rubber of a certain thickness a band or ring be made according to my
invention it will resist tension to a greater degree than a flat india rubber ring
made from a sheet of the same thickness.
My improved india rubber bands or rings are made of a corrugated form, the
corrugations being preferably arranged concentrically and being of angular form,
though I do not restrict myself to this respect since other forms of corrugation
may be used. The corrugations may also be arranged radially instead of con-
centrically if desired.
My invention is particularly applicable to elastic bands for holding papers
together in place of the ordinary flat india rubber bands but my improved bands
may be employed for other purposes where elastic rings are required.

Improvements in India-rubber Bands or Rings.
I, LOUIS NISSIM, of 12, Leadenhall Street, in the City of London, Mechanist, 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;
My invention relates to elastic bands such as are usually made of india-rubber
or similar extensible material for the purpose of holding papers or in general for
embracing a greater or less number of loose articles loosely connected together.
The object of my invention is to make such bands of greater strength than
hitherto, the same thickness of rubber or the like being provided.
My improved elastic bands are made of a corrugated form, the corrugations
being either concentric or radial, and of any suitable shape.

page_text: In the acompanying drawings,
Figure 1 is a plan of a circular elastic band constructed in accordance with my
invention.
Figure 2 is a section on the line 2-2 Figure 1.
Figure 3 is a plan and
Figure 4 an edge view of a band having radial corrugations.
Figure 5 is a perspective view of a modified form.
Figure 6 is a perspective view of another modification a portion of the band
being broken away to show the section and
Figure 7 is a plan of a fourth modification.
Referring now to Figures 1 and 2 the band illustrated is somewhat similar to
the ordinary elastic bands cut from a sheet of india-rubber, said band is however
corrugated as shown at a. The corrugations are arranged concentrically and the
angles of said corrugations are right angles. It will be furthermore observed
that the lowest points of the troughs of the corrugations on
the upper
side of the band are in the same plane as the highest points of the troughs of the
corrugations on the under side. I do not, however, confine myself to the exact
shape of corrugation shewn in Figure 2 as the crests may be rounded if desired
and corrugations of different angles may be employed.
In Figures 3 and 4 the band is shewn as being corrugated radially and in
Figure 5 such a radially corrugated band is shewn in its deformed position en-
circling a roll of papers, for example, the roll being however not shewn in the
figure. Such forms of corrugation may advantageously be used when the band
is not required to be stretched to any great extent.
Figure 6 is a view of a band cut from a tube of elastic material, the corruga-
tion being disposed concentrically in planes perpendicular to the axis, a portion
of the band being broken out to shew the section. It will be observed that
Figure 6 exhibits the form taken by a band such as shewn in Figure 1 when
the same is stretched.
Figure 7 is a band of round or square section suitable for securing together the
ribs of umbrellas for example, being particularly adapted for this purpose, since
the tops of said ribs lie in the troughs of the inner corrugations as will be readily
understood.
Bands or rings made according to my invention will resist tension to a greater
degree than ordinary bands made of flat rubber; furthermore, in the case of
bands made with concentric corrugations such as shown in Figures 1 and 6, if
one part of the band breaks, the break will in general extend no further than
through one corrugation, whereas with an ordinary india-rubber band when once
it has begun to split it stretches at the break and the fracture extends from edge
to edge thereby rendering the same useless.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A band made of elastic or extensible material and provided with corrugations
substantially as set forth.
2. An elastic band constructed substantially as described with reference to any
of the accompanying drawings.
