PROVISIONAL SPECIFICATION.
Improvements in the Construction of Driving Belts.
We, NORMAN KNOWLES of Mossfield and Egyptian Mills, Bolton, Cotton
Spinner, and WILLIAM PHILIPSON of Hillfold Mill, Astley-Bridge near Bolton,
Pneumatic Tyre Manufacturer, both in the County of Lancaster, do hereby
declare the nature of our said invention to be as follows:
-
This invention relates to improvements in the construction of driving belts
composed of links mounted on metallic or other centres and consists in constructing
the said links of a core of india-rubber, canvas, or other suitable material or
substance, covered by a layer or layers of canvas or like material, secured together
by cement, india-rubber or other solution, after which the whole is vulcanized in
the ordinary manner, thus producing a strong pliable belt with great gripping and
driving power.

COMPLETE SPECIFICATION.
Improvements in the Construction of Driving Belts.
We, NORMAN KNOWLES of Mossfield and Egyptian Mills, Bolton, Cotton
Spinner, and WILLIAM PHILIPSON of Hillfold Mill, Astley-Bridge near Bolton,
Pneumatic Tyre Manufacturer, both in the County of Lancaster, do hereby
declare the nature of our said 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 improvements in the construction of driving belts
composed of links mounted on metallic or other centres and consists in constructing
the said links of a core of india-rubber, canvas, or other suitable material or
substance, covered by a layer or layers of canvas or like material, secured together
by cement, india-rubber or other solution, after which the whole is vulcanized in
the ordinary manner, thus producing a strong pliable belt with great gripping and
driving power.
Fig. 1, Sheet 1, is a longitudinal section of our improved driving belt.
Fig. 2 is a plan.
Fig. 3 is an enlarged section of a single link showing one method of constructing
same.
Fig. 4, Sheet 2, is a longitudinal end view of belt.
Fig. 5 is a plan of Fig. 4 showing metallic or other washers and centres flush on
sides of outer links.
Fig. 6 is an enlarged section of a single link with a core composed of layers of
canvas or other suitable material, and
Fig. 7 is an enlarged section of a single link with a solid core of india-rubber or
other suitable material.
Our
A are links comprising the belt, and B the metallic or other centres.
invention consists in the method or manner of constructing the links A, which is
as follows:-
On and round the metallic or other centres B is wrapped the layer or layers of
canvas or like material C, which after being wrapped on one centre B is carried or
passed to and round the other centre B and back again and so on according to the
Price 8d 1

page_text: number of layers required to produce the desired strength of link or belt. Each
link A may have a separate core F composed of layers of canvas or other suitable
material or materials, each layer being secured together by cement, raw india-
rubber, or other similar solution D as shown in Fig. 6. In this case the core F is
formed by folding canvas or other suitable material or materials until the same is
about equal in thickness to the diameter of the metallic or other centres B. The
core F may be solid or in one piece composed of either india-rubber, canvas, metal,
or other suitable material as shown in Fig. 7. After the core F has been placed
in position between the metallic or other centres B the whole is wrapped or
enclosed with the layer or layers of canvas or like material C, which may be
wrapped round as often as necessary to produce the desired strength of belt.
Between each layer of canvas or like textile material C is disposed cement, raw
india-rubber, or other similar solution D, after which the whole is congealed by
vulcanization in the ordinary manner, thus producing a strong pliable belt with
great gripping and driving power. The outside of the links A are covered
entirely with raw india-rubber D as shown by thick lines on plans, thereby
protecting the outer layers C and increasing the gripping power of the belt. In
making belts according to this invention the links A may be made separately, or
in broad pieces from which may be cut longitudinally a number of links by means
of a saw or other suitable cutting instruments. The links A are formed or
moulded on metallic centres equal in diameter to the centres B, which are removed
after vulcanization has been performed. After the links A have been formed they
are placed as shown in Figs. 2 and 5 on the centres B and are secured together by
the metallic or other washers E and the rivetting over of the ends of the centres B.
The metallic plates or other washers E may be sunk into the sides of the links A
as shown in Fig. 5.
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. Constructing the links of driving belts of layers of canvas or like textile
materials, secured together by means of cement, raw india-rubber, or. other similar
solution or material, and coated externally with raw india-rubber, the whole being
vulcanized to congeal the same, substantially as described.
2. Constructing the links of driving belts with a core composed of layers of
canvas or other suitable material secured together by means of cement, raw india-
rubber, or other similar solution or material, and wrapped with canvas or like
textile material or materials secured together by means of cement, raw india-rubber,
or other similar solution or material, and coated externally with raw india-rubber,
the whole being vulcanized to congeal the same, substantially as described.
3. Constructing the links of driving belts with a solid core composed of either
india-rubber, canvas, metal, or other suitable material wrapped with canvas or
like textile material or materials secured together by means of cement, raw india-
rubber, or other similar solution or material, and coated externally with raw
india-rubber, the whole being vulcanized to congeal the same, substantially as
described.
