page_text: LETTERS PATENT to Samuel Tweedale of Accrington in the County of
Lancaster Foreman mechanic for an Invention of "IMPROVEMENTS IN
MACHINERY FOR SPINNING FIBRES"
PROVISIONAL SPECIFICATION left by the said Samuel Tweedale at the
Office of the Commissioners of Patents on the 14th June 1882.
SAMUEL TWEEDALE of Accrington in the County of Lancaster Foreman Mechanic
"IMPROVEMENTS IN MACHINERY FOR SPINNING FIBRES
This invention relates to improvements in machinery employed for Spinning
wherein cranked wires are used for the purpose of preventing the spindle being
lifted during the act of doffing the bobbins or spools such wires heretofore being
screwed into the boss of the spindle tube or attached to partial reciprocating rod
or shaft or to bars and actuated by turning the wire by hand-imparting partial
rotation to the shaft or by sliding the bars carrying the wires
According to this my invention I dispense with the shafts and sliding bars and
mount the wire for each spindle upon a tilting counterbalanced carrier so that
when a spindle is being placed in position the underside of the wharle forces
backwards the wire until the wharle is passed whereon the wire carrier tilts on
its centre or fulcrum and carries the cranked part of the wire over the upper part
of the wharle which is thus prevented rising when a bobbin is being doffed or
lifted off
The spindle is released for removal by simply depressing the end of the carrier
nearest the wire and which may be done whilst in the act of removing the driving
band from the groove of the wharle whereon the spindles may be lifted out for
lubrication or other purposes.

"IMPROVEMENTS IN MACHINERY FOR SPINNING FIBRES
"
This invention relates to improvements in machinery employed for spinning
wherein cranked wires are used for the purpose of preventing the spindle being
lifted during the act of doffing the bobbins or spools such wires heretofore being
screwed into the boss of the spindle tube or attached to partial reciprocating rod
or shaft or to bars and actuated by turning the wire by hand imparting partial
rotation to the shaft or by sliding the bars carrying the wires
According to this my invention I dispense with the shafts and sliding bars and
mount the wire for each spindle upon a tilting counterbalanced carrier so that
when a spindle is being placed in position the underside of the wharle forces back-
wards the wire until the wharle is passed, the wire carrier tilting on its centre or
fulcrum hd carrys the cranked part of the wire over the upper part of the wharle
which is thus prevented rising when a bobbin is being doffed or lifted off.
The spindle is released for removal by simply lifting the end of the carrier and
which may be done whilst in the act of removing the driving band from the groove
of the wharle whereon the spindles may be lifted out for lubrication or other
purposes.
Such being the nature and object of this my said invention I will now proceed
to describe the particulars thereof and in order that the invention may be fully
understood I have hereunto annexed a sheet of drawings illustrative thereof in
which at
Fig 1 is an elevation of spindle having my improved carrier applied thereto.
Fig. 2 is a like elevation shewing the improved carrier tilted or raised back for
the removal or for replacing the spindle in and upon its tube.
Fig. 3 is an elevation of tube and my improved carrier shewn in section.
Fig. 4 is a plan of Fig. 3.
Figs 5 and 6 are elevation and plan of the carrier detached or shewn apart from
the spindle or tube.
The lower end of the cranked holding wire 1 is screwed into the projecting part 2
of the counterbalanced carrier 3 and when the spindle 4 is being placed in position
on and in its tube 5 the underside of the wharle 6 bears or acts upon the cranked
end 7 of the wire 1 forcing back the wire 1 and tilting the carrier 3 on its fulcrum
pin S (the latter being passed through the sides of the carrier 3 and through the
lug 9 of the tube 5) clear of the wharle 6 when the latter is down or passed to
the position shewn at Fig. 1 the heavy end 10 of the carrier 3 returns the carrier
on its pin 8 and the wire 1 to the holding position shewn at Fig. 1 It will thus
be seen that if the spindle 4 is placed on its tube 5 and allowed to fall the
wharle 6 self actingly tilts back the wire 1 and carrier 3 and the latter being as
described counterbalanced by part 10 will return the bent end of the wire over the
wharle G thus tho action is automatic the spindle 4 cannot be raised or lifted
when doffing or removing the bobbins or spools because if the wharle G be lifted
against the cranked end 7 of the wire 1 the motion being on the pin S the part 10
of the carrier 3 bears on or against the flange 11 of the tube 5, but when it is
necessary to remove the spindle for lubrication or other purposes the end 10 of the
carrier 3 is by the thumb or finger raised, the carrier then tilts on the pin 8
assuming the position shewn at Fig. 2 and the spindle is free for removal,

page_text: It will be understood that the drawings illustrate a spindle carrier and holding
wire complete each and every spindle having its own carrier and holding wire so
that any one spindle may be stopped released and removed without interference
with the remaining or adjoining spindles as heretofore on spinning frames whereon
the holding wires or fingers were mounted upon and operated simultaneously by a
longitudinal shaft or bar. Having thus fully described the nature and particulars
of this my said invention together with the manner in which the same is to be or
may be performed or carried into practical effect I would have it understood that I
claim as my invention
The movable or tilting carrier and pin 1 (combined with the spindle and
wharle 6. 4) for purpose herein described and constructed substantially as illustrated
by drawings annexed
In Witness whereof I the said Samuel Tweedale have hereunto set my
hand and scal this twelfth day of December in the year of our Lord
one thousand eight hundred and eighty two
