PROVISIONAL SPECIFICATION.
An Improved Method of Constructing Flanged Bobbins.
We, JOHN DIXON, of the firm of John Dixon and Sons, Steeton near Keighley
in the County of York, Bobbin Manufacturer, and JAMES LEE, of the same place,
Foreman, do hereby declare the nature of this invention to be as follows:-
This invention has for its object, the construction by an improved method of
what are commonly known as jointed bobbins used in the textile trades, by forming
the flanges and barrels in such a manner that, they are more firmly attached to
each other and in such a way, that any lateral pressure exerted on the inside or
between the flanges by the tight wrapping of the yarn on the bobbins, such strain
on the flanges is supported by the barrels instead of the supplementary bushes
driven into the barrels, or by screwed threads or pins applied to the flanges and
barrels in the manner as hitherto.
We
Te accomplish our object in the following manner-Each barrel is bored and
the ends turned for some distance, so that the section of the circumference at the
ends is dovetailed.
The flanges are prepared in the ordinary manner and recessed to the diameter of
the barrel, and in addition are bored conical to the same diameter and angle as the
turned dovetailed ends, the smallest diameter of the conical hole being equal to the
smallest diameter of the turned ends.
The flanges are glued and secured to the barrels by being forced thereon, the
smaller diameter in the flanges going on first, which compresses the wood at the
end of the barrels, the wood expanding again to its original diameter, on arriving
at the wider portion of the conical hole, thus dovetailing the flanges on to the ends
of the barrels and which may be further secured by driving a bush into the centre
hole of the bobbin, thereby giving additional strength and rigidity to the turned or
conical ends of the barrel.

An Improved Method of Constructing Flanged Bobbins.
We, JOHN DIXON of the firm of John Dixon and Sons, Steeton, near Keighley,
in the County of York, Bobbin Manufacturer, and JAMES LEE, of the same
place, Foreman, 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 has for its object, the construction of what are commonly known
as jointed bobbins such as are used in the textile trades, by a novel method of con-
necting the flanges and barrels of same in such a manner that, they are more
firmly attached to each other and in such a way that, any lateral pressure exerted
on the inside or between the flanges by the tight wrapping of the yarn on the
bobbins, such strain or outward pressure on the flanges is supported by the barrels
instead of supplementary bushes driven into the barrels, or by screwed threads or
pins applied to the flanges and barrels in the manner as hitherto.
In the accompanying drawings
Fig. 1 represents an elevation of a bobbin barrel partly in section showing the
ends turned in accordance with our invention.

page_text: Fig. 2 is an elevation of a bush suitable for insertion in the ends of barrels
constructed as shown by Fig. 1.
Fig. 3 is a section through a bobbin flange, and
Fig. 4 an elevation of a finished flanged bobbin partly in section.
Each barrel A is bored and the ends turned for some distance in a manner that
the outside circumference at each end is dovetailed somewhat as shown at A¹.
The flanges B are prepared in the ordinary manner and recessed at C to the
diameter of the barrel A, but in addition, the flanges are bored conical to about
the same diameter and angle as the turned dovetailed ends A' of barrels A, the
smallest diameter of the conical hole in the flanges B. being about equal to the
smallest diameter of the turned dovetailed ends A'.
The flanges B are glued, and may be secured on the barrels A by being forced
thercon in a similar manner as bobbin flanges of the ordinary construction, or by
any suitable means whereby sufficient pressure can be put upon the flanges B. to
force the same on the barrels A. The recessed side Cand the smaller diameter
of the conical hole in the flanges are placed on the barrel ends, and by applying
pressure to the flanges B. in the direction of the axis of the barrel A. the wood of
the dovetailed ends A¹ is compressed to such an extent as to allow the flanges B to
be forced on the barrel until the recesses C are in contact with the respective
shoulders D of barrel.
After the flanges B are placed on the barrels A. the contracted ends expand to
about their original diameter, thus dovetailing the flanges B on the barrel ends A',
which may be supported and strengthened by driving or pressing a bush E such as
shown by Fig. 2 into each end of the barrel A, or when the hole F of the barrel
is made parallel as shown by Fig. 5, a parallel bush may be used for supporting
and giving additional strength and rigidity to the turned or conical ends A of the
barrel for sustaining any lateral pressure between the flanges of the bobbin.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, we declare that what we
claim is,
1. The method of constructing flanged bobbins by turning each barrel end
conical, boring the flanges conical to the same angle and compressing the flanges
on the bobbin barrels subst. tially in the manner set forth.
2. The method of constructing flanged bobbins by turning each barrel end
conical, boring the flanges conical to the same angle, compressing the flanges on
the bobbin barrels and inserting a bush in the centre hole of barrel all
substantially in the manner set forth.
