Improvements in Spinning Frame Lifting Mechanism.
ALFRED HITCHON, Globe Works, Accrington, in the County of Lancaster,
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention relates to a part of the lifting mechanism of the yarn guide
rails of machines for spinning yarns, one part of which my improvement refers
to being known by the trade as the lifting poker and its cast iron shoe; the
latter is usually secured by a set screw pinching against the foot of the poker
within the socket hole of this poker shoe, which does not provide for the poker
being withdrawn and replaced with an accuracy of poker and its shoe being same
length overall when the pokers are withdrawn for cleaning or like purposes.
By my improved invention I make the shoe of the poker in the usual form but
I add what may be rightly termed an adjusting screw which has the effect of
raising or lowering the poker within by the movement of same; as a means of
showing how the same may be brought into effect, I make an incline plane at
the poker foot which has the effect of raising the poker upwards from its shoe
by same being tightened. I also provide a lock nut for securing such an adjust-
ment and provide that the poker and shoe can be taken apart without the afore-
said adjustment being disturbed thereby giving assurance of same being fixed
together in their original adjusted position.

Improvements in Spinning Frame Lifting Mechanism.
ALFRED HITCHON, Globe Works, Accrington, in the County of Lancaster,
Machinist, 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 a part of the lifting mechanism of the yarn guide rails
of machines for spinning yarns, one part of which my improvement refers to
being known by the trade as the lifting poker, and its cast iron feet, the latter
is usually secured by a set screw pinching against the foot of the poker within
the socket hole of this poker shoe, which does not provide for the poker being
withdrawn and replaced with an accuracy of poker and its shoe being same
length over-all when the pokers are withdrawn for cleaning or like purposes.
By my improved invention I make the shoe of the poker in the usual form,

page_text: but I add what may be rightly termed an adjusting screw which has the effect
of raising or lowering the poker within by the movement of same; as a means
of showing how the same may be brought into effect, I make an inclined plane
at the poker foot which has the effect of raising the poker upwards from its
shoe by same being tightened. I also provide a lock nut for securing such an
adjustment and provide that the poker and shoe can be taken apart without the
aforesaid adjustment being disturbed thereby giving assurance of same being
fixed together in their original adjusted position.
By the accompanying sheet of drawings my invention may be fully understood,
and as to where the same is applied to the several figures of such drawings I make
reference.
Sheet 1, Fig. 1, shews framework parts of a yarn spinning machine, and with
one ring rail and a pair of lifting pokers.
Figs. 2 & 3 shew the poker shoes in two views and a lower portion of a poker
end shewn as resting in same, the dotted line B shewing the inclined plane in
the poker as resting against end of set screw A which is in position for raising
the poker within the shoe by the action of same being further screwed up, when
it is secured to any decided fixed position by locking nut C. Set screw D secures
the shoe to the poker end to any position that has been defined by set screw A.
Fig. 4 is a plan view of 2 and 3.
Fig. 5 is a piece of the lower end of the lifting poker, to better illustrate the
inclined plane within same.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The incline plane formation on the lower end of spinning machine poker com-
bined with the adjusting screw A and locking nut C used for the purpose as
described and as illustrated in the accompanying sheet of drawings forming part
of this specification.
