Improvements in Self Contained Spindles Used in Ring Spinning
and Doubling Fibres.
I SAMUEL TWEEDALE of Globe Works Accrington in the County of Lancaster
Foreman Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improved combination of parts means and appliances
for supporting and centering the lower end of the bolster tubes of self contained
spindles where the said tubes are fitted loosely in their bolster carriers and the lower
end is free to move, the object being to accomodate itself to an unbalanced load.
In carrying out this invention I employ a shell the outside of which fits the hole or
bore in the bottom end of the bolster carrier the upper end fitting the outside of the
bolster tube. To enable the bolster tube to yield to an unbalanced load 1 cut a
number of longitudinal or vertical slits in the upper part of the shell.
The hole or bore of the bolster carrier is made larger opposite to the slit part of
shell and the lower part of the bolster carrier is tapered to allow it to have a limited
amount of play.
The shells can be stamped or cut from sheet metal and bent to cylindrical form the
joint not being closed forms one of the slits.

Improvements in Self Contained Spindles Used in Ring Spinning
and Doubling Fibres.
I SAMUEL TWEEDALE of Globe Works Accrington in the County of Lancaster,
Foreman 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 relates to improved combination of parts, means and appliances for
supporting and centering the lower end of the bolster tubes of self contained spindles
where the said tubes are fitted loosely in their bolster carriers, and the lower end is
free to move the object being to accomodate itself to an unbalanced load.
In carrying out this invention I employ a shell the outside of which fits the hole or
bore in the bottom end of the bolster carrier the upper end fitting the outside of the
bolster tube. To enable the bolster tube to yield to an unbalanced load, I cut a
number of longitudinal or vertical slots in the upper part of the shell.
The hole or bore of the bolster carrier is made larger opposite to the slit part of
shell and lower part of the bolster carrier is tapered to allow it to have a limited
amount of play.
The shells can be stamped or cut from sheet metal and bent to cylindrical form
the joint not being closed forms one of the slits.
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:-
Fig. 1 is a sectional view of spindle (and fittings) having my improvements applied
thereto, drawn about twice full size.
Fig. 2 is a like view illustrating the yielding shell inverted.
Figs. 3 and 4 are elevation and plan of the shell detached.
Fig. 5 is a view of shell inverted as applied in illustration Fig. 2.
Fig. 6 shews yielding part of the shell contracted or of bottle necked form.
At 1 is the bolster, its bore is of two diameters being at 2 slightly less than at
part 3.
Within the bore 2 is tightly fitted the plain or cylindrical part 4 of the shell, the
upper part of which is provided with slits 5 or parts cut away, so as to permit this
part of the tube to yield, at 6 is the lower part of the bolster tube 7 slightly tapered
and somewhat less in diameter than the bore of the bolster carrier. At 8 is a collar
or swell thereon, which fits nicely its bore, 9 is the spindle.
It will be seen that when the spindle is working with an unbalanced load, the slit
part 5 of the shell 4 yields and permits a limited amount of play to the lower end
of the bolster and the spindle, the bore of the bolster carrier being greater than
the diameter of the slit portion 5 of the tube 4 for purpose of permitting such
action.
At fig. 6 the slit yielding part of the tube 4 is shewn contracted or bottle necked,
this form may be used either in position as shown at fig. 6 or in the inverted position

page_text: of like tube as illustrated by figs. 2 and 5, in either case it will be understood that
the bore of the bolster carrier will be uniform or alike from top to bottom the lesser
diameter at 5 permitting the required yielding or play and movement of this part of
the shell for effecting the balancing of the bolster tube and spindle.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. The slit shell 4 combined with bolster tube, the bore of bolster carrier being
recessed or of varying diameters for purpose described and as illustrated by Figs. 1
and 2 of annexed drawings.
2. The slit shell as shown by Fig. 4 combined with bolster tube and bolster carrier
for purpose described.
