Improvements in the Manufacture of Belting.
I CHARLES EDWIN ANGUS of St. John's Leather Works, Newcastle-upon-
Tyne, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to the manufacture of belting and its objects are to
give a greater bearing surface upon the pulleys and therefore a greater development
of power, to give a better grip, and to cause the belting to run straight without the
use of flanges which have hitherto been found necessary for high speeds.
My improved belting is particularly adapted for high speeds with small pulleys,
and is more especially applicable in connection with dynamo machines.
The invention consists in forming the belting with longitudinal ribs or fillets
on the inner face and extending throughout its length, the inner face thus
presenting somewhat of a corrugated, grooved or waved form in cross-section.
The belting when run upon pulleys having circumferential grooves of a number
corresponding with that of the ribs has thus a bearing not only in the grooves
by means of its longitudinal ribs, but also by its normal or flat surface upon the
lands or portions between the grooves of the pulley. It will readily be understood
that in addition to this increased bearing surface the belting has a better grip,
and that as the ribs travel in the grooves of the pulley the belting is compelled to
run straight.
The invention can be carried out in various ways and the belting may be made
of leather, raw hide, india rubber, cotton or hair fabric, or other suitable material
or combination of materials. According to one way I stitch or otherwise secure
to the inner face of a plain belt of leather or other material longitudinal ribs
composed of a strip or of two or more superimposed strips of leather or other
material, and in order to give sufficient flexibility to allow the belting to pass round
the pulleys, small pieces or notches are cut out of the strips transversely at
intervals of about two inches more or less. According to another way I form the
longitudinal ribs of ropes made of cotton or other fibrous material stitched or
otherwise secured to the face of the belting. In applying the invention to what is
known as link belting 1 employ links of different depths in such manner that when
secured together in any usual way, ribs or thicker parts are formed longitudinally
of the belting, these ribs or thicker parts being adapted to take into circumferential
grooves in the pulleys.

Improvements in the Manufacture of Belting.
1. CHARLES EDWIN ANGUS of St. John's Leather Works, Newcastle-upon-
Tyne, Manufacturer, 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 has reference to the manufacture of belting and its objects are
to give a greater bearing surface upon the pulleys and therefore a greater
development of power, to give a better grip, and to cause the belting to run.

page_text: straight without the use of flanges which have hitherto been found necessary for
high speeds.
My improved belting is particularly adapted for high speeds with small pulleys
and is more especially applicable in connection with dynamo machines.
The invention consists in forming the belting with longitudinal ribs or fillets
on the inner face and extending throughout its length, the inner face thus
presenting somewhat of a corrugated, grooved or waved form in cross section.
The belting when run upon pulleys having circumferential grooves of a number
corresponding with that of the ribs has thus a bearing not only in the grooves by
means of its longitudinal ribs but also by its normal or flat surface upon the
lands or portions between the grooves of the pulley. It will readily be understood
that in addition to this increased bearing surface the belting has a better grip
and that as the ribs travel in the grooves of the pulley the belting is compelled to
run straight.
The invention can be carried out in various ways and the belting may be made
of leather, raw hide, india rubber, cotton or hair fabric, or other suitable material
or combination of materials. According to one way which is represented in
Figure of the accompanying drawings stitch or otherwise secure to the inner,
face of a plain belt a of leather or other material longitudinal ribs bbcomposed
of a strip or of two or more superimposed strips of leather or other material; three
longitudinal ribs each composed of three superimposed strips are shown in the
figure. If thought necessary in order to give sufficient flexibility to allow
the belting to pass round the pulleys when these are.very small, small pieces or
notches can be cut out of the strips transversely at intervals of about two
inches more or less. According to another way of carrying out my invention
represented in Figure 2 in which a again represents a plain belt I form the longi-
tudinal ribs of ropes bbb made of cotton or other fibrous material stitched or
otherwise secured to the face of the belting. In applying the invention to what is
known as link belting I employ links of different depths as will be well understood
in such manner that when secured together in any usual way, ribs or thicker parts
are formed longitudinally of the belting these ribs or thicker parts being adapted to
take into circumferential grooves in the pulleys.
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 I
claim is :-
1. The manufacture of belting with longitudinal ribs or fillets on the inner face so
that this face presents somewhat of a corrugated grooved or waved form in cross
section, substantially as and for the purpose hereinbefore described.
2. The manufacture of belting substantially as shown in Figure 1 for the
purpose herein before described.
3. The manufacture of belting substantially as shown in Figure 2 for the
purpose hereinbefore described.
4. The manufacture of link belting with links of different depths secured
together so as form ribs or thicker parts longitudinally of the belting such ribs or
thicker parts being adapted to take into circumferential grooves in the pulleys, as
herein before described.
