PROVISIONAL SPECIFICATION.
Improvements applicable to Ring Spinning, Doubling and Twisting
Spindles.
I, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the County
of Lancaster, Machine Maker, do hereby declare the nature of this Invention
to be as follows:-
This invention relates to improvements applicable to ring spinning, doubling
and twisting spindles, the object being to simplify the construction of the holding-
down arrangement and to prevent the catch from being displaced or overbalanced.
In carrying this Invention into effect the holding-down arrangement is con-
structed of two parts, the stand or pillar, and the hinged or swivel catch. The
stand or pillar is constructed of one piece of metal preferably by stamping it
out in such a manner that when doubled one end will form a jaw to receive the
catch and the pin upon which it is hinged.
The swivel or hinged catch is also constructed of one piece of metal, preferably
by stamping it out, and is made so that it forms no obstruction to the descent
of the ring rail and is so weighted that it will readily recover its position when
the spindle has been placed in the bolster.
To prevent the over balancing of the catch the slot forming the jaw of the
stand or pillar is made shorter than that part of the catch projecting over the
wharve of the spindle so that when a spindle is dropped into the bolster the
wharve forces the projecting part down the projecting part of the catch coming
against the stand or pillar and when the wharve has passed this projecting part
the catch regains its normal. position automatically.

COMPLETE SPECIFICATION.
Improvements applicable to Ring Spinning, Doubling and Twisting
Spindles.
I, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the County
of Lancaster, Machine 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:-
This invention relates to improvements applicable to ring spinning, doubling
and twisting spindles, the object being to simplify the construction of the holding-
down arrangement and to prevent the catch from being displaced or overbalanced.

page_text: In carrying this Invention into effect the holding-down arrangement is con-
structed of two parts, the stand or pillar, and the hinged or swivel catch. The
stand or pillar is constructed of one piece of metal preferably by stamping it
out in such a manner that when doubled one end will form a jaw to receive the
catch and the pin upon which it is hinged.
The swivel or hinged catch is also.constructed of one piece of metal, preferably
by stamping it out, and is made so that it forms no obstruction to the descent
of the ring rail and is so weighted that it will readily recover its position when
the spindle has been placed in the bolster.
In the accompanying Sheet of Drawings-
Figures 1 and 2 are elevations of a spindle shown in two positions and fitted
with my improved holding down arrangement.
Figures 3 and 4 are detail views of the stand or pillar and the catch respectively.
In these views,-a designates the spindle, a¹ its wharve, b the bolster, c the
spindle rail, d the oil cup, e the stand or pillar, which is fixed to the bolster by
a screw h or otherwise, f the catch and g the pin by which it is hinged to the
stand.
The stand e is stamped out of thin sheet metal, is slotted for part of its length,
and is bent over and doubled so as to form jaws el and a groove or recess e for
the catch as clearly shown in Fig. 3. The catch f is also stamped out of sheet
metal and is hinged to the stand e by a pin g which passes through it and the
jaws el of the stand.
To prevent the tipping over of the catch f the slot forming the jaw e¹ of the
stand è is made shorter than that part of the catch. f projecting over the wharve a¹
of the spindle a so that when a spindle is dropped into the bolster 6 from the
position shown in Fig. 2, the wharve a¹ forces the projecting part of the
catch down, this projecting part coming against the solid metal
of the stand e at the back of the recess 2 and when the wharve a¹
has passed, this projecting part the catch f regains its normal position (Fig. 1)
automatically, the heavy end of the catch being prevented from falling toward
the spindle wharve by the solid back of the recess e².
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 :-
The combination with the spindle a, its wharve a¹ and the bolster b, of the
stande and hinged catch f constructed, arranged and operating substantially as
herein set forth.
