Improvements in Driving Belts.
We JOHN M QUEEN of the firm of Messrs. John Hetherington & Sons of
Pollard Street Manchester in the County of Lancaster and WALTER MOORES
Foreman at the same place do hereby declare the nature of this invention to
be as follows:-
Our said invention relates to driving belts for transmitting motion in machinery
as is well understood and refers particularly to such belts as are used to communi-
cate motion from one revolving cone to another as is frequently the case in textile
and other machinery. When an ordinary belt is applied to this purpose it will be
evident that on each cone one edge or side only of the belt is in driving contact
with the periphery of the cone the other edge or side being slack and doing
practically little or no work. It will also be evident that the wider the belt the
greater will this defect become apparent. The object of our invention is to obviate
this disadvantage. We divide the belt in its breadth into several widths or rather
arrange a series of narrow belts side by side and connect the various widths to each
other in such a manner that while being to a certain degree independant of each
other they cannot nevertheless either encroach upon each other or become dis-
associated. To obtain this result we connect the several independent and parallel
widths comprising the belt by means of links of sheet metal or other material each
link extending between two adjacent widths. For example if a belt were composed
of say three equal and parallel widths of material the first link might extend from
the right hand side width to the centre width and so on alternately the links being
pitched the requisite distance apart. The effect of this arrangement is that while
the divided belt is by these connections made practically one belt the driving power
of such a belt is very materially improved. In using such a belt, that edge of the
belt which rides on the higher part of the cone surface (and which in a homo-
geneous belt does almost all of the work) has movement independent of the other
widths and therefore allows the central and other outside widths to have contact
with the cone periphery and thus take their proper share of the work. As has
been said the connecting links might be of sheet metal slotted or loosely pivotted
from width to width so as to allow of easy relative movement while preventing
over-riding or disconnection of the various widths or instead of applying the links
from width to width alternately as described we might pivot the links on the central
width loosely and at each side to the side widths the link rocking on the central

might loosely lace the various widths together or we might have lengths of wire or
cord at the back of the widths threaded through eyes in bars carried by the central
or other of the widths or we might use other similar means giving us the herein-
before referred to desired results.

Improvements in Driving Belts.
We JOHN MCQUEEN of the firm of Messrs. John Hetherington and Sons of
Pollard Street Manchester in the County of Lancaster and WALTER MOORES
Foreman at the same place do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement and accompanying drawings:-
Our said invention relates to driving belts for transmitting motion in and to
machinery as is well understood and refers particularly to such belts as are used to
communicate motion from one revolving cone to another as is frequently the case in
textile and other machinery, such for example as scutching machines slubbing and
intermediate frames and the like. When an ordinary belt is applied to the driving
of cones it will be evident that on cach cone, one edge or side only of the belt is in
driving contact with the periphery of such cone the other edge or side being slack
and doing practically little or no work. On both cones the belt grips most strongly
the largest diameter with which it is in contact and as on the driving cone this
point of gripping contact is diagonal to that on the driven cone it will be evident
that the driving must be faulty and irregular. The wider the belt the more
apparent will this defect become.
The object of our invention is to obviate these disadvantages. We divide the
belt in its breadth into several widths or rather arrange a series of narrow belts
side by side and connect the various widths to each other in such a manner that
while they are for practical purposes independent of each other they cannot never-
theless either encroach upon each other or become disassociated. To obtain this
result we connect the several independent and parallel widths composing the belt
by means of pivotted sheet metal links, each link extending between two adjacent
widths.
The construction and advantages of the improved belt will be more apparent
from an inspection of the annexed drawing which is a plan view of two cones
connected by a driving belt of the improved description.
For
In the said drawing we show a belt extending between two cones A and B and
composed of four widths or strips a bed although it will be apparent that a
greater or less number might be used. The various widths are connected by
links e e e² of thin sheet metal which are pivotted loosely on rivets / secured to
the strips. These links are distributed at suitable intervals upon the belt.
example the links e connect the first outer strip a to the second strip : the links e'
connect the strip to the stripe and the links, the stripe to the strip d. The
butt ends of the respective strips are joined by means of hooks g, or by any
suitable fastener or they might be sewn together. The butt ends of the strips
are preferably made to break joint in the manner shown in the drawing. The
effect of this arrangement is that while the divided belt is by these connections
made practically one belt the driving power of such a belt is very materially
increased. In our improved belt, the outer opposite edges or strips or d of the
belt which rides on the higher part of each cone surface as at x in the drawing and
which in a homogeneous belt would do almost all of the work, have movement
independent of the other widths and e and therefore allow the central strips to
have driving contact with the peripheries of the cones so as to take their proper
share of the work. It will be obvious that instead of using flat metal links to
connect the various widths as shown we might use other means such as links of
leather or wire or the like; or the connecting links might be of sheet metal slotted
or loosely pivotted from width to width so as to allow of easy relative movement
while preventing over-riding or disconnection of the various widths. Instead of
applying the links from width to width alternately as described we might pivot the

page_text: links on the central width loosely and at each side to the side widths the link
rocking on the central pivot. We might moreover use suitable substitutes for the
links. For example we might loosely lace the various widths together or we
might have lengths of wire or cord at the back of the widths threaded through eyes
in bars carried by the central or other of the widths or we might use other similar
means giving us the hereinbefore referred to desired results.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
A driving belt for transmitting motion between cones and consisting of two or
more parallel strips connected together at intervals by means of loose links or
attachments so as to allow the respective strips independent freedom of motion for
the purposes and substantially as described and shown.
