JOSHUA VALENTINE EVES of Brooklands Knock County Down Ireland Mill
Manager do hereby declare the nature of this invention to be as follows:-
This improved bush for bobbins or pirns, used on spinning frames consists of a
loose ring which is free to revolve on the spindle and which acts as an antifriction
bush between the spindles and the bobbins or pirns which are "dragged" to cause
them to take up the yarn as spun.
This loose ring or bush is placed upon the spindle and is carried up and down
thereon by the traversing of the builder or bobbin rail.
In doffing or changing the bobbins or pirns the loose ring or bush is left upon the
spindle the bobbins or pirns being mado of a sufficiently large internal diameter to pass
over or on to the loose ring.
These loose bushes or rings are by preference made of metal and grooved
circumferentially.
By the use of those loose bushes for the bottom of bobbins or pirns for spinning
frames simpler and cheaper pirns or bobbins can be employed.

COMPLETE SPECIFICATION.
Improvements connected with the Spindles of Spinning Frames for
Flax or other Fibres.
I, JOSHUA VALENTINE EVES of Brooklands, Knock, County Down, Ireland, Mill
Manager, do hereby declare the nature of this invention and in what manner the saine
is to be performed, to be particularly described and ascertained in and by the following
statement:
The object of this invention is to provide a bush or ring to carry the bobbins or
pirns on the spindles which will prevent friction between them and will allow of the
use of cheaper or softer forms of pirns without fear of their clinging to the spindle or
interfering with the regulated amount of "drag" or tension.
It consists of a loose bush or ring of metal or other bard material applied to the
spindle and free to revolve thereon, with which the lower end of the bobbin or pirn
engages.
It will be described with reference to the accompanying drawing which as an
example shows parts of a spindle and building rail sufficient to illustrate the
invention.
.
Fig. 1, is elevation of top part of spindle with part of builder rail, pirn and busb in
section.
Fig. 2, 3 and 4 sectional elevations of three modified forms of bushes or rings.
The spindle A, builder rail B, and the pirn C are all made in the usual form.
On the spindle A, I place a loose bush or ring D. This ring or bush D internally
I form or bore out to fit the spindle but free to move or revolve thereon, and externally
to fit inside the base of the bobbin or pirn. I prefer to make it with a flange upon
which the base of the bobbin or pirn will rest as in Fig. 1 though if desired such may
be dispensed with as in Figs. 2 and 3.
The loose bush or ring may be of wood or metal and of any desired shape and when
made of metal may be formed in any of the usual ways for making small metallic
articles. In fig. 1 the bush is shown turned and bored, with bottom flange: 6g. 2 is

page_text: a plain bush of wood or motal: fig. 3 a bush formed of spiral wire and fig. 4, a bush
formed of drawn or stamped brass.
The loose bush or ring D is carried up and down on the spindle by the traversing
of the builder or bobbin rail. The bobbin or pirn is placed on the spindle over the
loose bush and the two rotate together the friction on the spindle being almost reduced
to nil.
When doffing or changing the bobbins or pirns the loose bush or ring D remains
upon the spindle and the bobbins and the yarn thereon are removed without them.
By the use of these loose bushes on the spindles I estimate that a very considerable
saving can be effected.
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 use or combination with a spinning frame spindle of a loose bush or ring with
which the base of the pirn or bobbin engages substantially as described.
