Improvements in Belting.
I, ERNST GUSTAF OLSON, of Mariedal, Gothenburg, in the Kingdom of
Sweden, Master Workman, do hereby declare the nature of this invention to be as
follows:-
Belting as hitherto known, has been produced in long bands, and an endless.
belting has thus always been provided with a joint. Such a joint has required a
so called belt clip or a special seam, but notwithstanding the most careful work-
manship, the joint has always been a weak point in the belting. There are however
many instances in which a specially manufactured endless belting would be very
convenient, as for instance, in cases where an expanding roller is employed for
stretching the belting, or when small portable machines are to be driven.
Now the object of this invention is the production of such endless beltings.
In carrying the invention into effect, the beltings are made preferably of cloth,.
which, in the form of a long band, either single, double, or multifold, is wound
upon itself into a ring corresponding in size to the endless belting required. The
number of the windings varies according to the thickness of the belting required,.
that is, it varies as the belt required is to be single, double or multifold.
The band which is to form the endless belting may be single; double with the
fold at one edge and sewn together at the other edge, or folded at both edges and
a longitudinal seam in the middle; or manifold. In winding the band, care should
be taken that the ends will be about opposite each other, and if a band folded, as
above described with a central longitudinal seam, is employed, the longitudinal
edges are first folded over on one face of the band for a distance somewhat longer
than one winding of the band, and then over on the opposite face, for the remaining
distance, to the end that the longitudinal seam may always lie inside the belting,.
so that the belting when complete is without seam on its inner as well as on its.
outer surface. At the point where the folding is changed from one face to the
other as above described, a cross cut is made on each edge of the band for a
distance equal to a fourth part of the whole width of the band. When a double
folded band is employed, the moiety or other part of its thickness is taken away at
each end to such a length as the said ends should overlap each other, in order that
the belting may be uniform in thickness. A joint may also be made in the same
way in the band itself, if the latter require to be joined. After the winding of
the band, the various turns or windings are secured together by means of longi-
tudinal stitched seams. Also some adhesive binding material may be employed
when winding the band, such material being adapted to cause the windings to
adhere to each other.

Improvements in Belting.
I, ERNST GUSTAF OLSON, of Mariedal, Gothenburg, in the Kingdom of
Sweden, Master Workman, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and
5. ascertained in and by the following statement :-
Belting, as hitherto known, has been produced in long bands, and an endless.

page_text: belting has thus always been provided with a joint. Such a joint has required a
so called belt clip or a special seam, but, notwithstanding the most careful
workmanship, the joint has always been a weak point in the belting. There are,
however, many instances in which a specially manufactured endless belting would
be very convenient, as, for instance, in cases where an expanding roller is employed
for stretching the belting, or when small portable machines are to be driven.
Now the object of this invention is the production of such endless beltings.
In carrying the invention into effect, the beltings are made preferably of cloth,
which, in the form of a long band, either single, double or multifold, is wound
upon itself into a ring, corresponding in size to the endless belting required. The
number of the windings varies according to the thickness of the belting required,
that is, it varies as the belt required is to be single, double or multifold.
On the accompanying drawings
Figure 1 represents sections of the band, and
Figure 2, a belting.
As shown in Figure 1, the band, which is to form the endless belting, may be
single, as at a; double with the fold at one edge and sewn together at the other
edge, as at ; or folded at both edges and a longitudinal seam in the middle, as.
at c or manifold, as at d. In winding the band, care should be taken that the
ends will be about opposite each other, and, if the band C, folded as above described
with a central longitudinal seam, is employed, the longitudinal edges are first
folded over on one face of the band, as shown in dotted lines, for a distance
somewhat longer than one winding of the band, and then over on the opposite
face, for the remaining distance, to the end that the longitudinal scam may always
lie inside the belting, so that the belting, when complete, is without seam on its
inner, as well as on its outer, surface. At the point where the folding is changed
from one face to the other as above described, a cross cut is made on each edge of
the band for a distance equal to a fourth part of the whole width of the band.
When a double folded band is employed, the moiety or other part of its thickness
is taken away at each end to such a length as the said ends should overlap each
other, in order that the belting may be uniform in thickness.
made in the same way in the band itself, if the latter require to be joined. After
A joint may also be
the winding of the band, the various turns or windings are secured together by
means of longitudinal stitched seams. Also some adhesive binding material may
be employed when winding the band, such material being adapted to cause the
windings to adhere to each other.
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
An endless belting constructed of a band of cloth or other suitable pliable
material, of single, double or manifold thickness, wound as described into the form
of a ring corresponding to the length of belting required, the ends of the band
and the various windings thereof being secured in position, either during or after
the winding operation, by glutinous material, sewing, or otherwise, substantially as
described.
