PROVISIONAL SPECIFICATION.
Improvements in and connected with Driving Belts.
I, ISAAC JACKSON of Glossop in the County of Derby, Belt Fastener Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to driving belts of considerable width, and particularly to
textile and woven belts.
It is well known that the costs of such belts increases in a much greater ratio
than the direct increase in their width. For example, a forty-eight inch belt will
cost very much more than two twenty-four inch belts of the same thickness and
length, and these again will cost more than three sixteen inch belts.
The object of this invention is to assimilate the costs of wide driving bands to
those of the narrower bands, and at the same time to make the belts practically
endless, that is to say without a cross joint.
For these purposes I construct the wider belts of two or more narrow belts
joined together along their selvedges by means of suitable fasteners, such for
example as those described in the Specification of the Letters Patent granted
to me No. 20050 dated the 9th December A.D. 1890, and in the Provisional
Specification filed with my application for Letters Patent No. 19789 dated the
14th November A.D. 1891.
The widths constituting the belt are arranged relatively to each other so as to
break joint by preference. Thus, if three widths are employed, the second may
be commenced two or three feet from the commencement of the first, and the
third at a similar distance from the commencement of the second. This distance
will depend upon the local conditions in each case, but it is preferred that it should
be such that two pairs of ends or two joints should not be on one pulley at the same
time. The ends of the widths may be joined together by suitable fasteners, or by
lacing when the belt is put to work.
Dated this 23rd day of November A.D. 1891.

COMPLETE SPECIFICATION.
Improvements in and connected with Driving Belts.
I, ISAAC JACKSON, of Glossop; in the County of Derby, Manufacturer of
Belt Fasteners, 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 :-
This invention relates to textile and woven belts of considerable width.
It is well known that the cost of such belts increases in a much greater ratio
than the direct increase in their widths. For example, a forty eight inch belt
will cost very much more than two twenty four inch belts of the same thickness
and length, and these again, will cost more than three sixteen inch belts.
The object of this invention is to assimilate the relative costs of wide driving
belts to those of narrower belts of the same united widths, and at the same time, to
make the belts practically endless, that is to say without a cross joint.
For these purposes, I construct the wider belts of two or a greater convenient
even number of narrow belts, firmly joined together along their selvedges side by
side, by means of suitable fasteners, such for example as those described in the

page_text: Specification of Letters Patent granted to me No. 20050 dated the 9th December
1890, and in the Complete Specification left with my application for Letters
Patent No. 19789 dated the 14th November A.D. 1891.
The several widths constituting the belt are arranged relatively to each other
so as to break joint. Thus, if four widths are employed, the second may commence
at two feet, more or less from the end of the first, the third at a similar distance
from the end of the second, and the fourth at the same distance from the end of
the third. This distance will depend upon the local conditions in each case,
and it is preferred that it should be such that two pairs of ends, or two joints
should not be on one pulley at the same time. The ends of the widths may be
fastened by suitable fasteners, or by lacing, when the belt is put to work.
I prefer to employ an even number of narrow belts for the reason that in this
case there will be two selvedges along the centre of the belt, and as the selvedges
are the stronger parts of the belts, the greater strength will be in an advantageous
position. desire it to be understood that I do not exclude the use of an odd
number of narrow belts from my invention, but that in all cases prefer where
convenient, to use an even number.
The accompanying drawings illustrate in what manner I may carry out my
In these drawings,
invention.
Figure 1, is a plan of a composite belt constructed according to this invention,
the central length of the belt being shewn as torn away.
Figure 2 is a plan of the belt represented by Figure 1, fitted upon two pulleys.
Wide belts constructed as herein described, are particularly applicable for
cambered and round faced pulleys such as those shewn by Figure 2; as in the
case illustrated, the two middle widths A B, may be made longer than the two
outer widths CD.
In making up the belt, the narrow widths are brought as closely as possible
edge to edge, and are in this position firmly connected together at intervals of
about 10 or 12 inches by the fasteners E.
The cross joints F may be made by means of similar fasteners, by laces or by
other means.
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 1
claim is :-
Wide textile and woven belts, made up with two or more narrow belts arranged
closely side by side and firmly connected together, and with their cross joints at a
distance from each other, substantially as and for the purposes hereinbefore described
and as illustrated by the accompanying drawings.
