Improvements in the Construction of Combined Step and Bolster
Bearings for the Spindles of Spinning and Doubling Machines.
I SAMUEL TWEEDALE of Globe Works Accrington in the County of Lancaster
Manager do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of step and bolster
bearings of. what are known as self contained spindles of spinning and doubling
machines such spindles having a bolster tube fitted loosely in a holster carrier and
the object of this invention is to so construct the same that an upright position of the
spindle is ensured and at the same time the bolster tube is free to move so as to
accommodate itself to an unbalanced load.
This invention consists in the application of a spring to one side of the bolster tube.
The pressure of this spring acting in the same direction as the pull of the driving
band and thus keeping the bolster tube in contact with the side of the hole in the
bolster carrier and as the hole in the bolster carrier and the periphery of the bolster
tube are made parallel to the centre line of the spindle the pressure of the spring
tends to maintain the spindle in an upright position by pressing the parallel sides of
the bolster tube and bolster carrier together.
The hole in the bolster carrier is made larger than the diameter of the bolster tube
and when the spindle is running with an unblanced load the spring allows the
bolster tube to move slightly and permits the spindle to find its own centre thus
enabling the same to be run at a greater speed without jar or vibration.
The whirl is made so as to surround a part of the bolster carrier, bolster tube and
spring.
To prevent the bolster tube turning in the bolster carrier I cut a groove in the
bolster carrier and bolster tube and the spring rests in these two grooves when in the
working position.
To enable the bolster carrier to hold a greater quantity of oil I recess the hole
in the bolster carrier and the outside of the bolster tube.

Improvements in the Construction of Combined Step and Bolster
Bearings for the Spindles of Spinning and Doubling Machines.
I, SAMUEL TWEEDALE of Globe works Accrington in the County of Lancaster
Manager, 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 relates to improvements in the construction of step and bolster
bearings of what are known as self contained spindles of spinning and doubling
machines such spindles having a bolster tube fitted loosely in a bolster carrier and
the object of this invention is to so construct the same that an upright position
of the spindle is insured and at the same time the bolster tube is free to move so as to
accommodate itself to an unbalanced load.
This invention consists in the application of a spring to one side of the bolster
tube. The pressure of this spring acting in the same direction as the pull of the
"

page_text: driving band and thus keeping the bolster tube in contact with the side of the
hole in the bolster carrier and as the hole in the bolster carrier and the periphery
of the bolster tube are made parallel to the centre line of the spindle the pressure
of the spring tends to maintain the spindle in an upright position by pressing the
parallel sides of the bolster tube and bolster carrier together.
The hole in the bolster carrier is made larger than the diameter of the bolster
tube and when the spindle is running with an unbalanced load the spring allows
the bolster tube to move slightly and permits the spindle to find its own centre thus
enabling the same to be run at a greater speed without jar or vibration.
The whirl is made so as to surround a part of the bolster carrier, bolster tube and
spring.
To prevent the bolster tube turning in the bolster carrier I cut a groove in the
bolster carrier and bolster tube and the spring rests in these two grooves when in the
working position..
To enable the bolster carrier to hold a greater quantity of oil I reces the hole in the
bolster carrier and the outside of the bolster tube.
Such being the nature and object of this my said invention the following is a
complete description of same reference being had to the accompanying drawings in
which: --
Fig. 1 is a side elevation partly in section of my improved construction of combined
step and bolster bearings for spindles.
Fig. 2 is a plan view of the bolster tube and bolster carrier drawn on line A-B
of fig. 1.
་
Fig. 3 is a similar view to fig. 2 but drawn to an enlarged scale.
Fig. 4 is a side elevation of the bolster tube and spring.
Fig. 5 is a sectional elevation of part of bolster tube, and bolster carrier drawn to
enlarged scale.
According to this my said invention in a groove 1 formed longitudinally in the
bolster tube 2 I fix a blade spring 3. The pressure of this spring 3 acting in
the same direction as the pull of the driving band 4 and in the direction indicated by
the arrows, thus the bolster tube 2 is kept in contact with the side of the hole 5 in the
interior of the bolster carrier 6, and as the hole 5 and the periphery of the bolster
tube 2 are made parallel to the centre line of the spindle and the pressure of the
spring 3 tends to maintain the spindle in an upright position by pressing the parallel
sides of the bolster tube 2 and the bolster carrier 6 together, (see fig. 5).
The hole 5 in the bolster carrier 6 is bored to a larger size than the outside circum-
ference 7 of the bolster tube 2 and when the spindle is running with an unbalanced
load the spring 3 allows the bolster tube 2 to move slightly and permits the spindle
to find its own centre thus enabling the same to be run at a greater speed without jar
or vibration.
The whirl 8 is made so as to surround a part of the bolster tube 2, bolster carrier 6
and spring 3 so that the pull of the band 4 on the whirl 8 is directly over the spring 3
(see fig. 1).
To prevent the bolster tube 2 turning in the bolster carrier-6 I cut a longitudinal
vertical groove 9 in the bolster carrier 6 and the spring 3 rests in the groove 1 in the
bolster tube 2 and the groove 9 in the bolster carrier 6 and locks or keys the parts in
position (see figs. 2 and 5).
To enable the bolster carrier 6 to hold a greater quantity of oil I recess the
hole 5 in the same and also bore to a greater depth or length as shewn at 10 the
oil passing through the holes 12-12 in the bolster tube 2 to the spindle and overflow
of oil passes down by way of the vertical groove.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what I
claim is : -
1. The spring 3 in combination with the bolster tube and bolster carrier 6 applied

page_text: and used as illustrated and described so as to assist the pull of the band 4 to
maintain the bolster tube in contact with the bolster carrier and set the spindle in an
upright position.
2. The spring 3 combined with the vertical grooves 1 and 9 whereby the rotation
of the bolster tube is prevented.
