PROVISIONAL SPECIFICATION.
Improvements in or relating to Spindles employed in Spinning and
Doubling Machines.
We, BENJAMIN ALFRED DOBSON, Machinist, of Kay Street Works, Bolton,
in the County of Lancaster, and EDWARD GILLOW, Foreman Mechanic, of the
same place, do bereby declare the nature of this invention to be as follows:-
Our invention relates to improved arrangements of stopping brakes and holding
down appliances for the spindles of spinning and doubling machines, and the chief
object of the improvements is to make a convenient brake and holding down
appliance.
In one arrangement the brake block and holding down wire are formed with or
secured to a bridle piece, which is fitted to slide at an angle in or on the base or
collar of the bolster, so that the brake can be pushed against the spindle wharve to
stop the spindle, and will when released slide back clear of the wharve. The
holding down wire can either be secured as described to this bridle piece, and move
as one piece with it, or it may be separately connected to a bridle piece or to the
bolster or spindle rail in any convenient manner.
One advantage of our arrangement is that 'the bridle piece can be put into
its working position after the spindle and bolster have been adjusted and the latter
secured to the spindle rail.

Improvements in or relating to Spindles employed in Spinning and
Doubling Machines.
We, BENJAMIN ALFRED DOBSON, Machinist, of Kay Street Works, Bolton,
in the County of Lancaster, and EDWARD GILLOW, Foreman Mechanic, of 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 ascertained in and .by
the following statement :-
Our invention relates to improved arrangements of stopping brakes and holding
down appliances for the spindles of spinning and doubling machines, and the chief
object of the improvements is to make a convenient brake and holding down
appliance.
In one arrangement the brake block and holding down wire are formed with or
secured to a bridle piece, which is fitted to slide at an angle in or on the base or
collar of the bolster, so that the brake can be pushed against the spindle wharve to
stop the spindle, and will when released slide back clear of the wharve. The
holding down wire can either be secured as described to this bridle piece, and move
as one piece with it, or it may be separately connected to a bridle piece or to the
bolster or spindle rail in any convenient manner.

page_text: And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figures 1, 3, 5, 7, 9 and 11 are elevations of spindles fitted with our improved
arrangement of stopping brakes and holding down appliances.
Figures 2, 4, 6, 8, 10 and 12 are views of the bridle piece detached.
In all these views a designates the spindle, the spindle wharve, c the bolster,
d the spindle rail, e the bridle piece, f the brake block and g the holding down
wire.
In Figs. 1 and 2 an incline e' is formed on the bridle piece e which in this example
carries both the brake block and the holding down wire 9.
When the incline e¹ is pushed up the edge of the bolster c the brake f comes
against the wharve & and stops the rotation of the spindle a and when released the
brake slides back by reason of the incline e' clear of the wharve.
To prevent the holding down wire g from being lifted accidentally or when
doffing we make a projection e³ on the bridle piece which engages a recess formed
to receive it in the base or collar of the bolster c.
In Figs 3 and 4 the holding down wire g is a spring wire separately secured by
a screw to the base of the bolster c.
In Figs. 5 and 6 the arrangement is the same as in Figs. 1 and 2 except that the
brake block is dispensed with and the holding down wire g alone is secured on the
bridle piece e.
In Figs. 7 and 8 two inclined slots are cut on opposite sides in the base of the
bolster c to receive two corresponding inclined slides e* on the bridle piece e and
the incline and projection are therefore dispensed with; the arrangement
otherwise is identical with that shown in Figs. 1 and 2.
The arrangements Fige. 9 and 10 and Figs. 11 and 12 are identical with the
arrangements Figs. 3 and 4 and Figs. 5 and 6 respectively except that they also
have slides fitting into inclined slots in the bolster base instead of the incline e¹
as in the earlier arrangements.
One advantage and special feature of our arrangements is that each bridle piece e
can be put into its working position after the spindle and bolster have been
adjusted and the latter secured to the spindle rail, and another feature is that the
bridle piece will when released automatically slide back into its normal position.
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-
1. The combination with the spindle of a spinning or doubling machine, of a
bridle piece fitted to slide at an angle in or on the base or collar of the bolster, said
bridle piece carrying either a brake block or a holding down wire or both brake
block and bolding down wire substantially as and for the purposes herein set
forth.
2. The several arrangements and combinations of parts substantially as herein
described and as shown on the accompanying drawings.
