Improvements in Means for the Band or Rope Driving of
Machinery.
We WILLIAM KENYON, GEORGE HENRY KENYON and EDWIN KENYON all
of the Firm of Messrs. William Kenyon and Sous, of the Chapel-field Rope Works,
Dukinfield, in the County of Chester, Rope Makers, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to the cases wherein bands or ropes are or may be used in
the driving of machines or parts of machines which require to be frequently started
and stopped. In such cases it has been customary to drive the machine or revolving
shaft or part through a clutch in order that the machine or the revolution of the
shaft might be stopped without arresting the movement of the band. Such clutches
are expensive and their use entails an amount of wear and tear. The object of our
invention is to dispense with such clutches.
We employ a pair or a combination of fast and loose pullies of special con-
struction and we employ forks or guides or suitable means for shifting the band
from the groove in the fast pulley into the groove in the loose pulley or vice versû.
The two pullies are formed and mounted so that their adjacent rims run close
together and the two meeting flanges are lower than the outside flanges-that is to
say are of less diameter than such outer flanges and are rounded or eased off so
that the band may be passed from one groove to the other without excessive
strain. The-said meeting flanges may be made only about large enough to check
the accidental passage of the band over the flanges. We may make the inner face
of the outer flange of the fast pulley straight or otherwise stated the said face
would be at right angles or thereabouts with the axis of revolution the angularity
of the other flange being increased.
The groove in the loose pulley may be simply rounded to suit the size of the
band. The loose pulley may run upon a sleeve formed upon or fixed to the fast
pulley so that the combination may be complete in itself for application upon a
shaft or the parts may be otherwise suitably adapted for application to the
machine or part to be rotated. When applying the pullies we prefer to arrange
for the fast pulley to be in line with the driver pulley upon the shaft from which
the movement is derived.

COMPLETE SPECIFICATION.
Improvements in Means for the Band or Rope Driving of
Machinery.
We WILLIAM KENYON, GEORGE HENRY KENYON and EDWIN KENYON all
of the Firm of Messrs. William Kenyon and Sons, of the Chapel-field Rope Works,
Dukinfield, in the County of Chester, Rope Makers, 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 and
accompanying drawings:-
Our invention relates to the cases wherein bands or ropes are or may be used in

page_text: the driving of machines or parts of machines which require to be frequently started
and stopped.
In such cases it has been customary to drive the machine or revolving shaft or
part through a clutch in order that the machine or the revolution of the shaft might
be stopped without arresting the movement of the band.
Such clutches are expensive and their use entails an amount of wear and tear.
The object of our invention is to dispense with such clutches.
We employ a pair or a combination of fast and loose pullies of special con-
struction and we employ forks or guides or suitable means for shifting the band
from the groove in the fast pulley into the groove in the loose pulley or vice versa.
The two pullies are formed and mounted so that their adjacent rims run close
together and the two meeting flanges are lower than the outside flanges-that is
to say are of less diameter than such outer flanges and are rounded or eased off
so that the band may be passed from one groove to the other without excessive
strain.
Our invention is illustrated by the accompanying drawing in which Fig. 1
represents a pair of pullies in section.
In the said fig. a is the fast pulley and 6 the loose pulley. The fast pulley is
formed with a tubular boss or sleeve a¹ upon which the loose pulley is mounted to
revolve so that the combination is complete in itself for application upon a shaft.
The meeting flanges at c are made only about large enough to check the accidental
passage of the band over the flanges. We may make the inner face of the outer
Hange of the fast pulley straight-or otherwise stated the said face would be at
right angles or thereabouts with the axis of revolution the angularity of the other
flange being increased.
Such a formation is indicated by Fig. 2.
The groove in the loose pulley may be simply rounded to suit the size of the
band as indicated in the drawing.
When applying the pullies we prefer to arrange the fast pulley to be in line with
the driver pulley upon the shaft from which the movement is derived.
We do not confine ourselves to mounting the loose pulley upon the boss of the
fast pulley.
Having now particularly described and ascertained the nature of our said
invention and in what mauner the same is to be performed we declare that what
we claim is.
The combination of pullies formed and applied substantially as and for the
purpose set forth and indicated.
