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

page_text: We, THOMAS COULTHARD of Preston in the County of Lancaster Machinist, and
JOHN SIMPSON of the same place, Mechanical Engineer 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.
Our improved hook is held in position over the whirl or wharve by the action of
a spring separate and distinct from the hook itself, the spring being placed within
an annular groove or recess formed in the under side of the bolster flange. The
hook is bent over at its upper end so as to overlap or project over the whirl or
wharve in the usual manner but its lower end is turned up so as to hook into and
thereby be pulled or drawn inwardly by the spring in the annular groove. The
spring may be in the form of an annular ring fitting loosely within the groove or
recess or may consist of a flat spring suitably curved and fitting tightly within the
groove. That part of the bolster flange where the lower end of the hook 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 hook. When it is desired to remove the
spindle and sleeve from the bolster the hook is pressed or sprung back (thereby
pulling at the spring in the annular groove below) so that its upper end may be
clear of the whirl or wharve whereupon the spindle and sleeve may be lifted out of
the bolster.

page_text: We, THOMAS COULTHARD, of Preston in the County of Lancaster, Machinist, and
JOHN SIMPSON, of the same place, Mechanical Engineer, do hereby declare the
nature of our invention for "IMPROVEMENTS IN RING SPINDLE APPARATUS
IN
MACHINES FOR SPINNING AND DOUBLING COTTON AND OTHER
EMPLOYED
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 doffing 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 our invention.
Our improved hook a is held in position over the whirl or wharve 6 by the
action of a spring c separate and distinct from the hook itself, the spring being
placed within an annular groove or recess d formed in the underside of the bolster
flange e.
The hook a is bent over at its upper end so as to overlap or project over the whirl
or wharve b in the usual manner but its lower end is turned up so as to hook into
and thereby be pulled or drawn inwardly by the spring c in the annular groove d.
The spring c may be in the form of an annular ring fitting loosely within the
groove or recess d (as shewn in Figs 2 and 3) or may consist of a flat spring
suitably curved and fitting tightly within the groove (as shewn in Fig 5). That
part of the bolster flange e where the lower end of the book a enters the annular
groove d 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 hook. When it is desired to remove the spindle
and sleeve g from the bolster, the hook a is pressed or sprung back (thereby pulling
at the spring c in the annular groove d below) so that its upper end may be clear
of the whirl or wharve b whereupon the spindle and sleeve may be lifted out of
the bolster.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The use or employment of a hook acting in combination with a spring placed
within a groove or recess formed in the under side of the bolster flange arranged
and operating substantially as described and shewn in the drawings for the purpose
specified.
