THOMAS HUGHES 4S Linver Road, Fulham, London, Engineer & GEORGE CHAPMAN
48 Linver Road, Fulham, London, Gentleman do hereby declare the nature of this
invention to be as follows:-
==
In carrying ont our Invention we employ a Strip or Band of Metal such as Steel,
Iron, Copper, &c. of the width that it is intended the Belt should be, and of such
thickness as is required to give it the necessary strength. On the Inner Face of
this Metal Band we fasten by means of Rivets a Strip of Canvas Leather or other
suitable material which is the same width as the Metal Band for the purpose of
affording the necessary grip of the Pulleys it passes over. In the case of wile
Belts we employ two Strips or Bands of Metal of such width as together make up
the required width of the Belt. These two pieces being fastened together side by
side by means of narrow Strips of the same metal rivetted on thein at suitable
intervals, thus allowing the Belt to fit closely to the Pulley the whole width of its
Face and providing for any convexity of the Face of the Pulley. In joining these
Belts we do not lap them but bring the two ends together and rivet them by
means of a piece of the same Metal on the upper Face of the Belt thus providing
a perfectly smooth and even surface to the Pulleys. The Metal of which the Beit
is made may be tinned painted or otherwise treated to preserve it from rust &c.
Dated this 14th day of January 1889.

COMPLETE SPECIFICATION.
An Improvement in the Manufacture of Driving Belts.
We, THOMAS HUGHES of 48 Linver Road Fulham, London, Engineer; and GEORGE
CHAPMAN of 48 Linver Road, Fulham, London. Gentleman 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:-
The object of our invention is to enable a driving belt for machinery to be manu-
factured which shall not-practically speaking, be affected by atmospheric influences,
and will not stretch-or lergthen, but with he light and durable, as well as cheap to
manufacture, and also lie well over the convex surface of a pulley.
According to our invention we employ a strip or band or bands of metal such as
steel, iron, copper &c., of the width that the belt is intended to be, and of such thick-
ness as is required to give it the necessary strength; the inner face of this flexible
metal band we cover with leather, knitted, woven, or felted fabric, or other suitable
material, for the purpose of obtaining the necessary grip upon the pulleys to which
the driving band is to be applied; this lining of leather or other material hereafter
for the purposes of this description termed "fabric," we preferably secure to the
metal band by means of rivets.
Our invention will be more fully understood by reference to the accompanying
drawings.
Figures 1 and 2 shew in vertical section taken on the line X Y of Figure 3 a
driving band or belt constructed according to our invention, Figure 3 being a plan of
a portion of same.
Figure 4 shews in plan and drawn to a smaller scale than the previous figures, a
construction of the belting suitable for a wider pulley.

page_text: A is the strip or band of metal which we preferably form of annealed steel; B is
the fabric lining for ensuring the necessary grip on the pulleys.

At Figure 1 the lining B is shewn of the same width as the steel band A and is secured
thereto by rivets. At Figure 2 the fabric is turned over the edges of the band and
the said edges are secured by rivets C as will be clearly seen by reference to Figure 2;
when found desirable we may cause the fabric to extend over both surfaces of the
metal band A.
When found desirable we may employ a cement or glue in addition to the rivets
for causing the "fabric" lining to have a greater adherence to the metal band.
When joining together the two ends of belts constructed according to our invention
we do not lap the said ends one over the other but we bring the two ends together,
and place a covering piece E of the same material as the band A over the joint and
rivet the pieces together as is shown in Figure 3 and thereby we retain a perfectly
smooth and even surface to the pulleys.
When producing wide belting according to our invention we employ several strips
or bands A A of such width as when together will make up the required width of the
beit, an example of such a belt when formed of two widths is shewn by Figure 4.
The various widths forming the belt we secure together by means of narrow strips F
of the same material as the band A. thus allowing the belt to fit closely to the
pulley throughout the whole width of its face whatever may be the convexity of the
latter.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In driving belts, the flexible metal band A in combination with the lining of
leather, knitted, woven or felted fabric or other suitable material B, such lining B
being secured thereto by rivets substantially as and for the purposes hereinbefore set
forth.
2. The arrangement and construction of wide width driving belts, substantially as
described and illustrated with especial reference to Figure 4 of the accompanying
drawings.
