Improvements in Ropes applicable for Driving Bands.
I, ROBERT COOKE SAYER, of 11, Clyde Road, Redland, Bristol, Civil Engineer,
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:
The object is to drive ropes by toothed gearing so that the driving teeth may
act on the spaces or teeth of one face of the rope and the driven teeth of a wheel
or wheels may be actuated by the spaces or teeth of the same or other faces of the
rope, also to obviate noise while being strong. And that when required
shall carry taath suit spaces formed in their pinions.
This object is illustrated by the attached drawing where
Fig. 1 shows a plan of the rope.
Fig. 2 a section at ab Fig. 1.
Fig. 3 a section at cd Fig. 1.
Fig. 4 a diagramatic view of the rope driving a pinion from a different face to
that by which it is driven.
Fig. 5 is a section of a rope carrying teeth secured during manufacture.
Fig. 6 a similar view, in part, to Fig. 5 with the teeth attached after manufacture
Fig. 7 is an elevation of Fig. 5.
The rope Z Figs. 1 to 4 is formed of rings 1 divided at 2 with a lug 3 on one
end to fit a cavity in the other carrying alternate sector sectioned links 4 pro-
jecting beyond similar links 5 and are of material to prevent noise and somewhat
elastic, while the links 5 give strength. Their sizes are regulated to form spaces of
equal pitch at different angles, spaces 6 being on top, 16 at ninety degrees, 26 at
forty five degrees and 36 at one hundred and eighty degrees from 6, and others
when required, so that either face may receive pitched teeth 7, as shown at
Figs. 2 and 4, where the rope Z is driven by the teeth
the spaces 6 and after passing round the toothless pulley 9 drives the pinion 10
of the wheel 8 entering
y its teeth entering the spaces 16 at an angle of ninety degrees from 6, and
hus avoiding twisting the rope Z.
Figs. 5 to 7 show a wire rope Z provided with teeth 7 and 17 connected by the
reb 11 which when required are multiplied like the above spaces 6, 16 and 26
or a like purpose.
Fig. 6 shows a means of securing the teeth by driving the web 11 through the
ope Z and riveting on the teeth 17 by rivets 12.
Having now particularly described and ascertained the nature of my said
vention and in what manner the same is to be performed, I declare that what
claim is:-
1st. A means of driving ropes by toothed gearing.
2nd. Ropes driven by toothed gearing giving out their power to toothed or
aced pitch wheels by the same series of them, or other series suitably arranged
different angles to obviate twisting the
оре
spaces formed in their pinions.
This object is illustrated by the attached drawing where
Fig. 1 shows a plan of the rope.
Fig. 2 a section at ab Fig. 1.
Fig. 3 a section at c-d Fig. 1.
Fig. 4 a diagramatic view of the rope driving a pinion from a different face to
that by which it is driven.
.
Fig. 5 is a section of a rope carrying teeth secured during manufacture.
Fig. 6 a similar view, in part, to Fig. 5 with the teeth attached after manufacture
Fig. 7 is an elevation of Fig. 5.
The rope Z Figs. 1 to 4 is formed of rings 1 divided at 2 with a lug 3 on one
end to fit a cavity in the other carrying alternate sector sectioned links 4 pro-
jecting beyond similar links 5 and are of material to prevent noise and somewhat
elastic, while the links 5 give strength. Their sizes are regulated to form spaces of
equal pitch at different angles, spaces 6 being on top, 16 at ninety degrees, 26 at
forty five degrees and 36 at one hundred and eighty degrees from 6, and others
when required, so that either face may receive pitched teeth 7, as shown at
Figs. 2 and 4, where the rope Z is driven by the teeth 7 of the wheel 8 entering
the spaces 6 and after passing round the toothless pulley 9 drives the pinion 10
y its teeth entering the spaces 16 at an angle of ninety degrees from 6, and
hus avoiding twisting the rope Z.
Figs. 5 to 7 show a wire rope Z provided with teeth 7 and 17 connected by the
reb 11 which when required are multiplied like the above spaces 6, 16 and 26
or a like purpose.
Fig. 6 shows a means of securing the teeth by driving the web 11 through the
ope Z and riveting on the teeth 17 by rivets 12.
Having now particularly described and ascertained the nature of
vention and in what manner the same is to be performed, I declare that what
my said
claim is:-
1st. A means of driving ropes by toothed gearing.
2nd. Ropes driven by toothed gearing giving out their power to toothed or
aced pitch wheels by the same series of them, or other series suitably arranged
different angles to obviate twisting the rope.

material calculated to secure strength and quietness of running, the whole sub-
stantially as described and shown on the drawing.
