I SAMUEL BROOKS of Union Iron Works West Gorton, near Manchester in the
County of Lancaster Machine Maker, do hereby declare the nature of the said invention,
to be as follows: :-
My invention relates to combinations and arrangements of mechanism for holding
down or preventing what are known as self contained spindles from lifting out of their
bearings also for stopping the rotation of the spindles to piece the thread and for
both holding down and stopping the rotation of the spindle, and my invention consists
in arranging a lever on a vertical pin or fulcrum on the collar of the bolster or bearing
for the spindle or on the spindle rail this lever thus moving horizontally and in fixing
or forming a hook on the lever to come above the warf to be just clear of it when
rotating but which will prevent the warf and thus the spindle from lifting or being
withdrawn from its bearings except when the lever is moved the lever being pressed
outwards by a helical or other spring-When the spindle is inserted in its bearings
the spring will give way and allow the warf to pass down until it comes under the
hook.
In some cases the hook is or may be made to enter a groove or come over a flange
specially formed on the lower part of the warf.
The arrangement above described, namely, the lever is also used as a brake, the
inner surface to come against the warf being if desired covered with leather or similar
material.
In some cases the lever above described is arranged to act both as a brake to stop
the spindle and to hold down the spindle, the hook acting to hold down the spindle
when the lever is not operated as a brake. According to another modification of my
invention a slide is arranged on the bolster and is acted upon in one direction by a
spring, this slide has a brake surface so that when moved towards and against the
warf of the spindle it will stop it and when the pressure upon it is removed the spring
will bring the slide and thus the brake surface away from the warf.

page_text: We THOMAS GOODBEHERE and FREDERICK BOSTOCK DODDS, Executors of the late
Samuel Brooks, of Union Iron Works, West Gorton, near Manchester, in the County
of Lancaster, Machine Maker, 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 invention relates to combinations and arrangements of mechanism for holding
down or preventing what are known as self contained spindles from lifting out of
their bearings also for stopping the rotation of the spindles to piece the thread, and
for both holding down and stopping the rotation of the spindle and the invention
consists in arranging a lever on a vertical pin or fulcrum on the collar of the bolster
or bearing for the spindle or on the spindle rail this lever thus moving horizontally
and in fixing or forming a hook on the lever to come above the warf to be just clear
of it when rotating but which will prevent the warf and thus the spindle from lifting
or being withdrawn from its bearings except when the lever is moved the levor being
pressed outwards by a helical or other spring-When the spindle is inserted in its
bearings the spring will give way and allow the warf to pass down until it comes under
the hook.
In some cases the hook is or may be made to enter a groove or come over a flange
specially formed on the lower part of the warf.
The arrangement above described, namely the lever, is also used as a brake, the
inner surface to come against the warf being if desired, covered with leather or similar
material.
In some cases the lever above described is arranged to act both as a brake to stop
the spindle and hold down the spindle the hook acting to hold down the spindle when
the lever is not operated as a brake.
According to another modification of the invention a slide is arranged on the bolster
and is acted upon in one direction by a spring, this slide has a brake surface so that
when moved towards and against the warf of the spindle it will stop it and when the
pressure upon it is removed the spring will bring the slide and thus the brake surface
away from the warf.
Fig. 1 is an elevation of a spindle (the upper part supposed broken away) connected
parts, and its bolster or bearings and connected parts shown detached from the rail
to which it is attached, such combination of parts being commonly termed "self
contained spindles."
Fig. 2 is a plan or end view looking from the point end of the spindle-These
figs. 1 and 2 illustrate one modification of the invention.
Figs. 3 and 4, and figs. 5 and 6, and figs. 7 and 8 are respectively views corre-
ponding to figs. 1 and 2 illustrating other modifications of the invention.

page_text: In the modification shown by figs. 5 and 7 the rail is shown to which the bolster
is attached and the lower part of the bolster is supposed to be broken away.
In each modification, a is the spindle, a¹ the sleeve secured to the spindle, the lower
end of this sleeve forms the warf a' for the driving band.
In figs. 1 and 2, and
and 4, a³ is the cone cup to fit and drive the cone of the
bobbin or spool used for spinning.
In figs. 5 and 6 and 7 and 8, which are such spindles as are generally used for
doubling and twisting, at are projections to fit the slot in the end of the bobbin or
spool and rotate it.
is the bolster of the ordinary construction in the interior of which the bearings
for the spindle are formed.
The exterior of the lower part of the bolster bis screw threaded for a screw nut b
or nuts by which it is secured to the rail c as illustrated in figs. 5 and 7.
In figs. 1 and 2 the collar formed on the bolster is shaped to receive a lever d
which oscillates upon a fulcrum formed by a screw or a pin passing through a hole
in the lever and screwing or being rivetted into the collar 62.
The lever d is formed by a flat portion with a vertical flange d² descending to near
the lower edge of the collar 12.
In the lever d a hook d³ is screw tapped, riveted or otherwise secured.
This hook d³ when in the position shown in figs. 1 and 2 comes over but without
touching the upper edge of the warf a² and will thus keep it from lifting until the hook
is withdrawn by oscillating the lever d.
The lever d is held in the position shown in figs. 1 and 2 (one edge coming against
the side of the bolster which thus acts as a stop) by a helical spring done end of
which is inserted in a hole drilled in the edge of the collar 3 of the bolster the other
end of the spring d* coming against the inside of the vertical flange on the
lever d.
When the spindle is taken hold of by one hand and the lever d is pressed by one
finger the spindle is readily removed from its bearings.
Figs. 3 and 4 show a modification same as that illustrated by figs. 1 and 2 except
that the hook d³ comes within a groove a* formed in the lower edge of the warf as
shown.
The modification shown by figs. 5 and 6 is similar to that shown by figs. 1 and 2
except that the inside of the lever d, (or a piece of leather or other suitable material d³
with which it is lined) is arranged when moved, to, come against the lower edge of
the warf to act as a brake to stop the rotation of the spindle.
When the lever d is moved to act as a brake upon the warf the hook pin ³ is
withdrawn or the hook pin d³ is sufficiently withdrawn to liberate the warf just before
the brake surface d of the lever comes against the warf.
The brake surface on the lever d figs. 5 and 6 is or may be arranged to act above
a slight flange on the lower edge of the warf a² and thus hold it down when acting as
a brake.
Or the lower edge of the warf is or may be bevelled or coned, the largest part of
the cone being nearest the rail c. The acting surface of the brake lever d in this case
is bevelled to correspond with the cone of the warf so that when the lever is acting
as a brake it will also hold down the warf.
In the modification shown by figs. 7 and 8, the collar 2 of the bolster is shaped to
fit the two sides of a slot in a plate e which is kept down upon the surface of the
rail when the bolster is secured therein by a projection 63 on each side of the
collar that overhangs the plate e which can thus slide to and fro freely.
The sliding plate e is pushed outwards towards the front of the rail e by a helical
spring done end of which is inserted in a hole in the edge of the collar 62, or in the
front edge of the rail c the other end acting against the end of the slot in the plate e
at the front of the rail c the spring thus drawing the plate e, until the other end of
slot in it is brought against the back side of the collar 6.
The front end of the slide e has an upward flange to which a piece of leather or

page_text: other suitable material d³ is attached to act as a brake upon the flange of the warf
when the slide e is pressed inwards by the operative.
The holding down hook d³ is formed in the modification shown by figs. 7 and 8, by
a thin flat piece of steel bent as shown and secured at its lower end by a screw to the
back edge of the collar 1.
The bolster bis secured in the rail cas shown in figs. 5 and 7 with the holding down
hook d³ by preference at the back of the rail e so as to be clear of the knot of the
driving band.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim as
the invention of the late Samuel Brooks is.
