PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Driving Belts.
We, GEORGE ANGUS AND COMPANY LIMITED of Saint John's Works,
Newcastle-upon-Tyne, Leather Merchants and Belting Manufacturers, and
ALFRED ROBINSON of the same place, Foreman, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to the manufacture of driving belts and consists in
manufacturing them from strips of leather or other suitable material of a width
equal to the thickness of the belt required, and bent into approximately V form
and placed one within another in a succession of V's from end to end of the belt,
the various pieces being secured together at intervals by transverse metal pins in a
similar manner to that adopted in securing the pieces of link or chain belting. In
practice each pin will pass through four more or less of the V pieces. According
to the width of belt required one or more sets of V pieces will be employed and
when there are two or more sets the same transverse pins will preferably pass
through both or all of the sets, or the sets can be hinged together longitudinally
as in some link belting.
The strips can be made sufficiently long to cover the adjoining rivet heads and
thus protect them from contact with clutch forks, pulley flanges or the like and
these lengthening parts may be bevelled so as to produce practically even edges on
the belt.
The pieces of which the belt is composed are preferably strips of leather which
has been heavily "dressed" so as to render it very pliable.
Belts made as above described are stronger than link or chain belting inasmuch
as they are composed of a smaller number of pieces; they have greater adhesion
to the pulleys and consequently effect increased transmission of power; their
pliability, when heavily dressed leather is used, enables them to adapt themselves
to crown pulleys or pulleys having a convex periphery without the belts being
hinged or arched; they have a certain amount of elasticity which renders them
suitable for dynamo electric machines driven by gas or other engines; and the
edges of the belts are peculiarly adapted for use with clutch forks employed for
putting them into or out of gear.

Improvements in the Manufacture of Driving Belts.
We, GEORGE ANGUS AND COMPANY LIMITED of Saint John's Works,
Newcastle-upon-Tyne, Leather Merchants and Belting Manufacturers, and
ALFRED ROBINSON of the same place, Foreman, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described aud ascertained in and by the following statement :-
.
This invention has reference to the manufacture of driving belts and consists in
manufacturing them from strips of leather or other suitable material of a width
equal to the thickness of the belt required, and bent into approximately V form
and placed one within another in a succession of V's from end to end of the belt,

page_text: the various pieces being secured together at intervals by transverse metal pins in a
similar manner to that adopted in securing the pieces of link or chain belting. In
practice each pin will pass through four, more or less, of the ✓ pieces. According
to the width of belt required one or more sets of V-pieces will be employed and
when there are two or more sets the same transverse pins will preferably pass
through both or all of the sets; or the sets can be hinged together longitudinally
as in some link belting.
The strips can be made sufficiently long to cover the adjoining pin or rivet heads
and thus protect them from contact with clutch forks, pulley flanges or the like
and these lengthening parts may be bevelled so as to produce practically even
edges on the belt.
The pieces of which the belt is composed are preferably strips of leather which
has been heavily "dressed" so as to render it very pliable.
Belts made as above described are stronger than link or chain belting inasmuch
as they are composed of a smaller number of pieces; they have greater adhesion
to the pulleys and consequently effect increased transmission of power; their
pliability, when heavily dressed leather is used, enables them to adapt themselves
to crown pulleys or pulleys having a convex periphery without the belts being
hinged or arched; they have a certain amount of elasticity which renders them
suitable for dynamo electric machines driven by gas or other engines; and the
edges of the belts are peculiarly adapted for use with clutch forks employed for
putting them into or out of gear.
In order that the invention may be fully understood we annex a sheet of
drawings which illustrate the same. In these drawings
Figure 1 is a face view partly sectional and Figure 2 is a side view of a piece
of driving belt made in accordance with our invention, the belt being composed of
four sets of V-pieces the two middle sets being hinged together longitudinally
while the V-pieces of each of the outside sets are secured together by the same
transverse pins that secure the V-pieces of the adjoining set.
Figure 3 is a view of the piece of belt looking in the direction of the arrow in
Figure 1.
Figure 4 is a detached view of one of the pieces or strips of leather before it is
bent into the V-form.
a a represent the V-pieces which as herein before explained and as clearly seen
in the drawings are placed one within another so as to form a succession of V's
from end to end of the belt. bare the transverse metal pins which secure the
V-pieces together; these pieces being punched with holes c c to receive the pins.
The inner ends of the pins are rivetted over washers d d. e e represent the
hinges which secure the two middle sets of V-pieces together longitudinally;
they consist of pieces of leather or other material secured to the V-pieces by the
same transverse pins bb; the ends of the V-picces should be bevelled as seen in
Figure 1 at the part against which the hinge pieces e e come.
In the belt shown in Figures 1, 2 and 3 the heads of the pins or rivets bb are
exposed. This is not generally an objection but if for any reason it may be
desired to protect the heads the strips a a can be lengthened as shewn in the
fractional view Figure 5 so as to cover them and the lengthening parts may if
desired be bevelled.
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:-
The manufacture of driving belts substantially as hereinbefore described.
of October 1894.
