PROVISIONAL SPECIFICATION.
Improvements in Ring Doubling Frames.
We, GEORGE NUTTER STOTT, ROBERT STOTT, and WILLIAM STOTT, of the
Firm of Robert Stott's Sons, of Spotland Mill, Rochdale, in the County of
Lancaster, Cotton Waste Spinners and Doublers, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to ring doubling frames and the object of our invention is
to stop the bobbin or spool on which the doubled yarn is being wound when an
end breaks without stopping the spindle thereby saving. wear and tear, simplifying
the machine and greatly relieving the strain on the spindle band which occurs
when a spindle is stopped as is now customary when an end of yarn breaks.
In a convenient arrangement for effecting this we secure upon the spindle, or
form with the wharve, a cone and above this cone we fit loose upon the spindle
a flanged boss which has a taper recess corresponding with the conc. The boss is
provided on its upper surface with pegs or the like which carry and drive the
bobbin or spool on which the yarn is to be wound. The forked end of a lever lies
preferably between the top of the wharve and the flange of the boss and this
lever is secured upon or connected to a rod which is actuated by a needle detector
mechanism (or otherwise) which raises the top roller when an end of yarn
breaks and simultaneously lifts the boss off the driving cone when, the boss
and the bobbin or spool which it carries stops while the spindle continues to .
revolve.
In place of the coned surfaces mentioned any suitable means such as a clutch
might be employed.

bobbin or spool on which the yarn is to be wound.
And in order that our invention may be fully understood and readily carried
into effect we have shown on the accompanying drawing an elevation partly in
section of a ring doubling spindle to which our improvements are applied.
In this view the spindle is marked a and the spindle wharve 6 formed with an
upper coned surface 6. The flanged boss c is tapered internally to fit upon the
cone b¹ and on its upper surface has any convenient number of pegs c' which enter
corresponding holes in the bottom of the bobbin or spool d. The forked or other
suitably prepared end of a lever, not shown, lies preferably between the top of
the wharve b and the flange of the boss and this lever is secured upon or
'connected to a rod which is actuated by a needle detector mechanism (or otherwise)
which raises the top roller when an end of yarn breaks and simultaneously lifts
the boss c off the driving cone b¹ when the boss and the bobbin or spool d which
it carries stops while the spindle a continues to revolve.
In place of the coned surfaces herein shown and described any suitable
-equivalent means such as a clutch might be employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Mounting the bobbin or spool upon the spindle of a ring doubling frame in
such a manner that when the end of yarn breaks the bobbin or spool is
disengaged and stopped without stopping the spindle substantially as herein set
.forth.
2. In combination, the coned surface 61 of the spindle wharve, the internally
tapered boss c carrying the bobbin or spool and means for disengaging the boss
and stopping the bobbin or spool without stopping the spindle substantially as
herein set forth.
Dated this 5th day of August 1896.
