PROVISIONAL SPECIFICATION.
Improved Means for Locking Collapsible Swifts for Reeling Frames.
I, WILLIAM HENRY HASLAM, of 75 Bradford Street, Bolton, in the County of
Lancaster, Cotton Yarn Merchant, do hereby declare the nature of this invention
to be as follows:-
!
The object of this invention is to provide improved means for locking or
retaining in its expanded position a collapsible swift used for reeling yarn.
The series of staves at the corresponding ends of the arms of the swift are con-
nected together in the usual manner, say by a strip of strong webbing, tape or the
like; but according to my invention one of the outside staves of this series is
connected to the adjacent stave of those which are fixed at the opposite ends of the
arms of the swift by a hinged flap so formed as to carry an adjustable catch which
engages when the swift
expanded with a catch or plate fixed on the inner side
of the aforesaid adjacent stave. By this means the position of the catch can be
adjusted to a nicety when required in case the connecting strip above described
becomes stretched by long use, or for any other reason.
On the hinge or the stave to which the flap is hinged, I further propose to fit
a spring which so acts upon the said flap that when the swift is collapsed to doff
the hanks the flap is closed in against the centre shaft of the swift so as not to
obstruct the ready removal of the hanks, and to be in a constant and convenient
position for use when again required for expanding the swift.
The flap which I prefer is made of wire so doubled as to leave a space or slot
between the two lengths the ends of which are bent out to fit in two eyes or bear.
ings thus forming pivots. The catch may be formed by two plates and an endless
piece of thin sheet metal tightly clamping the doubled wire and drawn together
by a screw or screws passing through the slot formed by the doubled wire.
The catch plate above described is so formed as not to interfere with the doffing
of the hanks.
Improved Means for Locking Collapsible Swifts for Reeling Frames.
I, WILLIAM HENRY HASLAM, of 75 Bradford Street, Bolton, in the County of
Lancaster, Cotton Yarn Merchant, 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:―
The object of this invention is to provide improved means for locking or retain-
ing in its expanded position a collapsible swift used for reeling yarn.

page_text: The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawing is a section of a collapsible reel or swift made according
to my invention and shown in its expanded state, Fig. 2 is a similar view of the
same collapsed, and Fig. 3 shows details of the various parts detached and drawn
to a larger scale.
The series of staves a (Figs. 1 and 2) at the corresponding ends of the arms b
of the swift, are connected together in the usual way, say by a strip 61 of strong
webbing, tape, leather or the like, but according to my invention one of the outside
staves a of this series is connected to the adjacent stave a of those which are
fixed at the opposite ends of the arms b of the swift by a hinged flap or stretcher c
so formed (preferably of wire) as to carry an adjustable catch d which engages when
the swift is expanded (see Fig. 1) with a catch or plate e fixed to the inner side of
the aforesaid adjacent stave. By this means the position of the catch
adjusted to a nicety when required in case the connecting strip b¹ above described
becomes stretched by long use, or any other reason.
can be
On the hinge (or on the stave a to which the stretcher c is hinged) I further
propose to fit a spring f which so acts upon the stretcher that when the swift is
collapsed (see Fig. 2) to doff the hanks, the stretcher is closed in against the centre
shaft I of the swift so as not to obstruct the ready removal of the hanks, and to be
in a constant and convenient position for use when again required for expanding
the swift.
I prefer to make the flap or stretcher c of wire (see Fig. 3) so doubled as to leave
a space or slot between the two lengths, the ends of which are bent out so as to fit
into the eyes or hearings of the hinge plate thus forming pivots. The catch d
may be formed by two plates and an endless piece of thin sheet metal tightly
clamping the doubled wire of the stretcher c and drawn together by a screw or
screws passing through the slot formed by the double wire of the stretcher c
as shown at Fig. 3.
The catch plate e above described is so formed as not to interfere with the
doffing of the hanks.
It will be understood that any required number of these stretchers can be used
according to the length of the reel.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
The improved means for locking, retaining, and unlocking the staves of collaps-
ible swifts substantially as hereinbefore described and illustrated by the drawings
annexed.
