Improvements in Driving and Stop Mechanism for the Spindles of
Doubling, Twisting, and other like Machines.
We BRINTONS LIMITED of Kidderminster in the County of Worcester, Carpet
Manufacturers, EDWIN BEDFORD of 102 Lea Street, Kidderminster aforesaid
Spinning Manager and CHARLES OSBORNE of 34 Park Street, Kidderminster
aforesaid, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to driving and stop mechanism for the spindles of
doubling, twisting and other like machines and consists in constructing such
mechanism so that the spindles are driven by friction and also so that the act of
putting the friction devices out of contact brings a brake into operation.
According to our invention we make the spindle wharl cylindrical, its surface
being either uncovered or covered with leather or other like material. In frictional
contact with this wharl is a driving wharl or wheel covered with leather or other
like material and carried on a rod or spindle which runs in a tube or sleeve. The
driving wharl or wheel and the tube or sleeve are supported on one end of a bent
lever the other end of which constitutes a brake to the spindle wharl, the position
of the brake being diametrically opposite the driving wharl. This wharl is driven
by means of a band or cord from any convenient part of the machine. The pull
of this band combined with the weight of the brake end of the lever, this end being
the heavier, keeps the driving wharl normally in contact with the spindle wharl.
Upon pressing the brake end upon the spindle wharl the driving wharl through
the movement of the lever is thrown out of contact and the rotation of the spindle
is therefore stopped.

Improvements in Driving and Stop Mechanism for the Spindles of
Doubling, Twisting, and other like Machines.
We, BRINTONS LIMITED of Kidderminster in the County of Worcester, Carpet
Manufacturers SUSANNAH BEDFORD of 102 Lea Street, Kidderminster aforesaid
Widow Administratrix of Edwin Bedford of 102 Lea Street, Kidderminster
aforesaid, Spinning Manager, deceased, and CHARLES OSBORNE of 34 Park
Street, Kidderminster aforesaid, Mechanic 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 :-
This invention has reference to driving and stop mechanism for the spindles of
doubling, twisting and other like machines and consists in constructing such
mechanism so that the spindles are driven by friction and also so that the act of
putting the friction devices out of contact brings a brake into operation.
According to our invention we make the spindle wharl cylindrical, its surface
being either uncovered or covered with leather or other like material. In
frictional contact with this wharl is a driving wharl or wheel covered with leather

page_text: or other like material and carried on a rod or spindle which runs in a tube or
sleeve. The driving wharl or wheel and the tube or sleeve are supported on one
end of a bent lever the other end of which constitutes a brake to the spindle
wharl the position of the brake being diametrically opposite the driving wharl.
This wharl is driven by means of a band or cord from any convenient part of the
machine. The pull of this band combined with the weight of the brake end of
the lever, this end being the heavier, keeps the driving wharl normally in contact
with the spindle wharl. Upon pressing the brake end against the spindle wharl
the driving wharl through the movement of the lever is thrown out of contact and
the rotation of the spindle is therefore stopped.
The accompanying drawing is an elevation partly sectional of driving and stop
mechanism constructed in accordance with this invention. A represents the spindle
wharl, and B is the driving wharl which is normally in contact with the wharl A
and drives it by friction. The wharl B is supported on a rod or spindle H which
runs in a tube or sleeve C. The wharl B is driven from any suitable part of
the machine by a band or cord G passing round the pulley I. The said wharl
and the tube C are supported on one end of a bent lever E pivoted at F; the
other end of the lever constitutes a brake D to the wharl A this brake being as
regards this wharl diametrically opposite the wharl B. The pull of the band G
in driving combined with the weight of the brake end of the lever E, this end
being the heavier, keeps the wharl B normally in contact with the wharl A.
When it is required to stop the rotation of the wharl A the brake end D of the
lever is pressed against the wharl A and by the movement thus given to the lever
on its pivot F its other end moves the wharl B out of contact with the wharl A
and the rotation of this wharl and its spindle is thereby stopped. The spindle H
is lubricated by means of an oil cup or reservoir J on the end of the lever E and
Burrounding the tube C; the oil enters the tube by two holes K K connected by
a groove L. Opposite the upper hole which is in line with the bottom of the
cup J, a hole M is bored in an oblique upward direction through the spindle.
By the centrifugal force due to the rotation the oil passes up through the hole M
and then to the top of the tube C and it returns down the outside of same to the
cup J.
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 :-
An arrangement of driving and stop mechanism for the spindles of doubling,
twisting and other like machines in which arrangement the spindles are driven by
friction and the act of putting the friction devices out of contact brings a brake
into operation, substantially as herein before described and represented in the
accompanying drawing.
