A New or Improved Method of Rope Driving.
We, WILLIAM BAMBER of Mount Pleasant Mill, Cotton Spinner, and FRANK
GOODLAD of 24 Blackhorse Street, Mill Manager, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows
This invention relates to a new or improved method of rope driving and refers
to the use of cotton, hemp, or other textile ropes on flat faced strap, leather,
or other belt pulleys in lieu of what are known as rope or grooved pulleys. In
employing a rope or ropes on a flat faced pulley an ordinary or what is well known in
the trade as a strap or rope fork is employed for moving the said rope or ropes
from the fast to the loose pulleys and vice-versa. If desired a screw or its equiva-
lent may be employed to regulate the tension of the rope or ropes to compensate
for stretch and the like. If desired the face of the strap pulley may be rovided
with concaved or other indents to allow of increased frictional surface, the said
indents being so constructed that the rope or ropes may be moved from one to the
other with the least possible friction or wear on the rope or ropes employed.

We, WILLIAM BAMBER of Mount Pleasant Mill, Cotton Spinner, and FRANK
GOODLAD of 24 Blackhorse Street, Mill Manager, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-

caved or other indents to allow of increased frictional surface, the said indents
being so constructed that the rope or ropes may be moved from one to the other
with the least possible friction or wear on the rope or ropes employed.

Fig 1 is a sectional end elevation of fast and loose flat faced pulleys-Fig: 2
a side elevation of Fig: 1-Fig: 3 a sectional end elevation of flat faced pulley
provided with concaved indents-Fig: 4 a side elevation of Fig: 3 with rope or
band fork arrangement, and Fig: 5 a side view of rope or band fork arrangement
in Fig: 4.
A is a shaft; B fast flat faced pulley; C loose flat faced pulley; D fast flat faced
pulley provided with concaved indents; E loose flat faced pulley provided with
concaved indents, and G the bands or ropes composed of either cotton, hemp, or
other textile materials or substances. The fast flat faced pulley B is secured on
the shaft A by the key H, and the flat faced pulley C is loosely mounted on the
shaft A, and is held in position by the metallic washers I secured to the shaft A
by the set screws K. The fast flat faced pulley B and the loose flat faced pulley C
are placed side by side and in close proximity to each other as shown in Fig: 1
so that the ropes or bands G may be slid from one to the other easily and readily
when required or desired. The ropes or bands G are mounted on the peripheries
of the flat faced pulleys B as shown and by the rotating action of the driving
pulley the other flat faced pulley is driven by means of the bands or ropes G
mounted thereon. The bands or ropes G are moved from the fast flat faced pulley B
to the loose flat faced pulley C by the fork composed of the bowls or rollers M on
the pins or centres O secured to the sliding bar P mounted in the fixings R, the
latter being secured to any suitable fixing or other support such as the under side
of a work room floor or anywhere else most convenient. The peripheries of the
flat faced pulleys D and E may-if desired-be provided with the concaved or
other indents S as shown in Figs: 3 and 4 to allow of increased frictional surface
for the bands or ropes G, the said indents being constructed with rounded corners
or edges to allow of the bands or ropes G being easily and readily moved from one
If desired
pulley to the other with the least possible friction or wear on the same.
the tension of the bands or ropes G may be regulated to compensate for stretch
and the like by means of the screw at present employed for moving the counter or
driving shaft to regulate the tension on straps or belts now in use.
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:
1. In combination with flat faced strap pullies the use of cotton, hemp, and other
textile ropes, and the means for moving the same from the fast pulleys to the loose
pulleys and vice-versa, applied and operating substantially as described and as
illustrated for the purposes set forth.
2. In combination with the flat faced strap pulleys provided with concaved
indents the use of cotton, hemp, and other textile ropes and the means for moving
the same from the fast pulleys to the loose pulleys and vice-versa, applied and
operating substantially as described and as illustrated for the purposes set forth.
