Improvements connected with the Spindle Apparatus of Ring
Spinning and Doubling Machines.
- We, THOMAS COULTIARD, Machinist, THOMAS COULTHARD, Junior, Machinist,
and JOHN HENRY TOULMIN, Machinist, all of Cooper Road, Preston, in the County
of Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to "self contained" spindle apparatus of the Rabbeth
type and has for its object firstly an improved arrangement of parts whereby the
bolster and footstep bearings mounted within a tube answering also as an oil
chamber may be readily withdrawn from and replaced within the bolsten stock
without necessitating the removal of the spindle and secondly an improved con-
struction of the holding-down hook usually employed in such apparatus for
preventing the spindle from being lifted up out of position during the operation
of doffing.
In carrying out the first part of our improvements we bore a central hole
straight through the bolster stock or pillar and close the said hole at the bottom
by means of a screw-threaded flanged or collared plug. The combined upper
and lower bolster bearing-preferably of the well-known "gravity" type-fits.
easily within a tube-closed at its lower end--which in turn fits easily within
the central hole in the bolster stock or pillar-the lower or closed end of the tube
resting upon the screw plug below. To withdraw the bolster and footstep hearing
and its enclosing tube from the bolster stock or pillar it is merely necessary to
unscrew and remove the screw plug whereupon the said tube and bolster and
footstep bearing will drop down out of the bolster stock or pillar leaving the
spindle undisturbed.
Our improved holding-down hook is made of stout wire the upper catch or lip
part standing over the spindle whirl or wharve in the usual way whilst the lower
part is bent round at right angles to the vertical stem part in the form of a
circle within a groove or recess formed in the bolster flange or collar. The front
portion of the circular bent part of the wire answers as a weight to overbalance
and keep the catch or lip portion of 'the hook above in position over the spindle
whirl and is made to project somewhat beyond the front of the bolster flange so
as to be readily movable or tipped up when the hook above is to be moved from
over the spindle whirl or wharve.

We, THOMAS COULTHARD, Machinist, THOMAS COULTHARD, Junior, Machinist,
and JOHN HENRY TOULMIN, Machinist, all of Cooper Road, Preston, in the County
of Lancaster, 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 "self contained" spindle apparatus of the Rabbeth
type and has for its object firstly an improved arrangement of parts whereby the
bolster and footstep bearings mounted within a tube answering also as an oil
chamber may he readily withdrawn from and replaced within the bolster stock
without necessitating the removal of the spindle and secondly an improved con-
struction of the holding-down hook usually employed in such apparatus for
preventing the spindle from being lifted up out of position during the operation
of doffing.
In carrying out the first part of our improvements we bore a central hole
straight through the bolster stock or pillar and close the said hole at the bottom
by means of a screw-threaded flanged or collared plug. The combined upper
and lower bolster bearing preferably of the well-known" gravity" type-fits
easily within a tube closed at its lower end-which in turn fits easily within
the central hole in the bolster stock or pillar-the lower or closed end of the tube
resting upon the screw plug below. To withdraw the bolster and footstep bearing
and its enclosing tube from the bolster stock or pillar it is merely necessary to
unscrew and remove the screw plug whereupon the said tube and bolster and
footstep bearing will drop down out of the bolster stock or pillar leaving the
spindle undisturbed.
Our improved holding-down hook is made of stout wire the upper catch or lip
part standing over the spindle whirl or wharve in the usual way whilst the lower
part is bent round at right angles to the vertical stem part-in the form of a
circle within a groove or recess formed in the bolster flange or collar. The front
portion of the circular bent part of the wire answers as a weight to overbalance
and keep the catch or lip portion of the hook above in position over the spindle
whirl and is made to project somewhat beyond the front of the bolster flange so
as to be readily movable or tipped up when the hook above is to be moved from
over the spindle whirl or wharve.
In the accompanying drawings,
Fig. 1 is a vertical sectional view shewing the construction of our improved
spindle apparatus;
Fig. 2 an elevation of the bolster stock or pillar; and
Fig. 3 a plan view of the same.
Figs. 4 and 5 are respectively sectional and plan views of the removable tube
which holds or contains the bolster.
Fig. 6 is a plan view of our improved holding-down hook.
a is the bolster stock or pillar and b a screw-threaded plug which closes the
bottom of the stock a. At Figs. 7 and 8 is shewn another form of plug 6 which
may be screwed upon the ordinary outer screw-threading of the bolster stock a.
c is the combined upper and lower bolster bearing which fits easily within the
removable tube d. Its lower end may either rest upon the bottom of the tube d,
or it may be suspended (as shewn in the drawings) by means of notches and
catches arranged at its upper end.

page_text: e is the bolster flange or collar having the circumferential recess or groove f
which receives the lower horizontal part of our improved holding-down hook the
upper catch g of which stands over the spindle whirl or wharve h in the usual way
whilst a projecting part gl provides means for tilting up the holder from the front
of the apparatus and so moving the catch g backwards out of the way of the
wharve h when the spindle s has to be lifted out of its bolster.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
1. In spindle apparatus of ring spinning and doubling machines the combination
with a bolster such as c contained within a removable tube closed at its lower end
with a stock or pillar and a lower closing plug substantially as herein described
and shewn in the drawings for the purpose specified.
2. In spindle apparatus of ring spinning and doubling machines the employ-
ment of a holding-down hook constructed and arranged substantially as herein
described and shewn in the drawings.
