PROVISIONAL SPECIFICATION.
Improvements in and connected with Spindle Bearings for Ring
Frames.
I, ISAAC. WALSH, of Beach Cottage, Gorton Lane, West Gorton, in the County of
Lancaster, Foreman Spindle Maker, do hereby declare the nature of this invention to
be as follows:-
My invention relates to spindle bolsters for ring spinning and doubling frames and
consists in improvements in the bolster and the means for holding down the spindle. "
I make the foot of the spindle flat with bevilled edges and bore out the lower end of
the bolster with a tubular drill or cutter so as to leave a central peg forming a table
for the flattened foot of the spindle to rest upon, with a cavity round the peg constitu-
ting an oil reservoir and chamber for the settlement of any dirt. Above the table the
bore of the bolster fits the spindle for a short length, and is enlarged above this point
up to the top, where the bolster is tapped with a screw thread and has a short bush
screwed into it forming a second bearing for the spindle.
The bolster is formed with a collar to fit upon the spindle rail and secured to the
latter by a nut screwed upon the part projecting below the spindle rail. The collar
has a groove turned into it into which an open steel hoop is sprung formed at one end
with an upright blade turned over at the top so as to be above the wharve when the
spindle is placed into the bolster and prevent it from being lifted when doffing. As
the pull of the driving band is towards one side, the bolster will wear on that side.
The holding down devices hitherto used being fixed to the collar do not allow the
position of the bolster to be changed, but with my improved arrangement the bolster
can be turned partly round at times and the bolding down clip turned in the groove
as required, so that a more uniform wear and longer duration of the bolster is
obtained.

COMPLETE SPECIFICATION.
Improvements in and connected with Spindle Bearings for Ring
Frames.
I ISAAC WALSH of Beach Cottage Gorton Lane in the County of Lancaster
Foreman Spindle 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:-
My invention relates to bearings or bolsters for the spindles of ring spinning and
doubling frames and consists in improvements in said bearings or bolsters and the
means for holding down the spindle.
On the drawings appended hereunto
Figure 1 shows my improved bearing and holder in section and
Figure 2 the same in outside view.
1 make the foot of the spindle a flat with bevilled edges as shown at a¹ and bore out
the lower end of the bearing or bolster with a tubular drill or equivalent cutter so as
to leave a central peg c forming a table for the flattened foot of the spindle to rest
upon, with a cavity round the peg e constituting an oil reservoir and chamber for the
settlement of dirt. Above the peg c the bore of the bolster or bearing fits the
spindle for a short length up to d and is enlarged above this point up to the top, where
the bolster b is tapped with a screw thread and bas a short bush e screwed into it
forming a second bearing for the spindle. The latter is preferably reduced in diameter
D

page_text: between the upper and lower bearings, as shewn, for the purpose of enlarging the
capacity of the oil chamber and facilitating the flow of the lubricant to the bearing
surfaces.
The bolster or bearing b is formed with a collar ƒ fitting upon the spindle rail and
is secured to the latter by a nut g screwed upon the part projecting below the spindle.
The collar has a groove turned into it as shewn into which is sprung an open steel
hoop formed at one end with an upright blade ' turned over at the top so as to be
above the wharve i when the spindle is placed into the bearing and prevent it from
being lifted when doffing. As the pull of the driving band is towards one side the
bearing will wear on that side. The holding down devices hitherto used being fixed to
the collar of the bearing do not allow the position of the latter to be changed as the said
devices would interfere with the driving band but with my improved arrangement of
spindle holder the bearing can be turned partly round at times and the holder h
turned in the groove of the collar fas required so that a more uniform wear and longer
. duration of the bearing is obtained.
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
Firstly. The arrangement or construction of bearings or bolsters for ring spindles
substantially as herein before described and illustrated by the drawings.
Secondly. A bolster or bearing for ring spindles bored out so as to leave a central
solid peg (c) for the spindle to rest upon and to fit the lower part of the spindle and
having a bush (e) screwed into the upper part of the said bolster or bearing substan-
tially as herein before described and illustrated by the drawings.
Thirdly. Spindle holders arranged in such a manner that they can be turned round
the bolstor or bearing for the spindle substantially as hereinbefore described.
Fourthly. A spindle holder (h) formed with an open hoop sprung into a groove
turned into the spindle bolster or bearing substantially as herein before described and
illustrated and for the purpose set forth.
Dated this 14th day of June 1890.
