IMPROVEMENTS IN RING SPINDLE APPARATUS EMPLOYED IN MACHINES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1884

page_text: J, THOMAS COULTHARD of Preston in the County of Lancaster, Machinist, do
hereby declare the nature of said Invention for "IMPROVEMENTS IN RING SPINDLE
APPARATUS EMPLOYED IN MACHINES FOR SPINNING AND DOUBLING COTTON AND
OTHER FIBROUS SUBSTANCES" to be as follows:-
This Invention of improvements in ring spindle apparatus employed in machines
for spinning and doubling cotton and other fibrous substances relates to "self
contained" spindle apparatus of the Rabbeth type and consists in a novel
arrangement of the hook employed for preventing the spindle and sleeve which
carries the bobbin from being lifted out of place in the bolster during the operation
of doffing or excepting when required. My improved hook is preferably composed
of tempored steel wire bent over and brought together so as to be double at that
part which projects over the upper side of the whirl or wharve and which is
formed in the usual manner the doubled wire being continued downwards as far
as the bolster rail where it is bent at nearly right angles to the stem or upright
portion of the hook the two extremities of the wire being opened out and curved
so as to fit into an annular groove or recess formed in the under side of the
bolster flange. That part of the bolster flange where the lower divided portion
of the hook branches off on each side and enters the annular groove is cut out or
slotted so as to receive and act as a stop and also as a guide bearing for the lower
end of the stem. The two extremities of the wire within the annular groove are
curved or bent in such manner as to act as springs and to press against the upper
side of the groove thereby keeping the upper end of the hook over the whirl or
wharve. When it is desired to remove the spindle and sleeve from the bolster
the hook is pressed back or sprung away clear of the whirl or wharve whereupon
the spindle and sleeve may be lifted out of the bolster.
In lieu of the arrangement of doubled wire as above described in which round
wire would preferably be employed my improved hook may be made of Dat wire

whirl or wharve in the usual manner whilst the bottom part within the annular
groove would be bent in the form of a ring and curved or shaped so as to
give the requisite spring pressure to the upper end of the hook as hereinbefore
referred to.
I, THOMAS COULTHARD, of Preston in the County of Lancaster, Machinist, do
hereby declare the nature of my said Invention for "IMPROVEMENTS IN RING
SPINDLE APPARATUS EMPLOYED IN MACHINES FOR SPINNING AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
This Invention of improvements in ring spindle apparatus employed in machines
for spinning and doubling cotton and other fibrous substances relates to "self
contained" spindle apparatus of the Rabbeth type and consists in a novel
arrangement of the hook employed for preventing the spindle and sleeve which
carries the bobbin from being lifted out of place in the bolster during the operation
of dofting or excepting when required.
In the accompanying Drawings Fig. 1. is a side elevation of an ordinary
arrangement of Rabbeth spindle apparatus, and Fig 2 is an underneath view
(partly in section), Fig 3 a side view (also partly in section), and Fig 4 a back
view of so much of the spindle apparatus as is necessary for illustrating the
application of iny invention."
My improved hook a is preferably composed of tempered steel wire bent over
and brought together so as to be double at that part which projects over the upper
side of the whirl or wharve band which is formed in the usual manner, the
doubled wire being continued downwards as far as the bolster rail c where it is
bent at nearly right angles to the stem or upright portion of the hook, the two
extremities of the wire being opened out and curved so as to fit into an annular
groove or recess & formed in the under side of the bolster flange c.
That part of the bolster flange where the lower divided portion of the hook
branches off on each side and enters the annular groove is cut out or slotted so
as to receive, and act as a stop and also as a guide bearing for, the lower end of
the stem.
The two extremities of the wire within the annular groove & are curved or bent
in such manner as to act as springs and to press against the upper side of the
groove thereby keeping the upper end of the hook over the whirl or wharve.
When it is desired to remove the spindle and sleeve g from the bolster, the hook a
is pressed back or sprung away clear of the whirl or wharve b whereupon the
spindle and sleeve may be lifted out of the bolster.
In lieu of the arrangement of doubled wire as above described, in which round
wire would be preferably employed, my improved Look may be made of flat wire,

whirl or wharve in the usual manner whilst the bottom part within the annular
groove would be bent in the form of a ring and curved or shaped so as to
give the requisite spring pressure to the upper end of the hook as hereinbeforo
referred to.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
"
The use or employment of a hook, constructed, arranged, and operating
substantially as described and shewn in the Drawings for the purpose specified.
