1, HENRY TAYLOR, of Little Moor Lane, Oldham, in the County of Lancaster,
Spinning Master, do hereby declare the nature of this invention to be as follows:-
The bobbins at present in use in frames known as ring spinning frames are made
practically parallel or nearly so from end to end without flanges or bottoms though
slightly tapering at each end.
In spinning when "gaiting" or beginning on a fresh bobbin the yarn is wound
upon the bobbin, each succeeding layer increasing the thickness until the required
number of layers is wound upon each.
When the desired number of layers has
been laid on the filling of the bobbin proceeds regularly up to the top until full.
These first layers wound upon a smaller diameter receive less twist and the yarn is
consequently weaker and more liable to break.
It is, to obviate this defect chiefly that this invention is designed and to provide a
bobbin which will wind the yarn at the first layer of the same diameter as each
succeeding one until the bobbin is full.
It consists essentially in making the bobbin with an inclined or tapered collar or
shoulder at or near the base to receive the first layer of yarn spun or wound upon it.
It will of course be understood that the yarn is at present wound upon an inclined
surface formed by the material itself after the desired number of layers have been first
laid on to raise the lower part of the wound bobbin to the desired thickness.
In carrying out the invention I may form the bobbin of a solid piece and turn it
down to the required size with an inclined collar or shoulder at the base or such a
collar or shoulder may be separately made and applied. This shoulder tapers or
inclines towards the top of the bobbin for a length equal to that of the lift or chase
and may be flat beneath or inclined in that direction also. Below the shoulder the
bobbin is formed to fit the cup of the spindle.
By the invention I consider I effect a saving in spinning by preventing waste and
breakage I produce a more uniform quality of yarn and at the same timo provide a
bobbin that will be stronger and less liable to breakage or damage than many of those
at present in use.

page_text: I, HENRY TAYLOR, of Little Moor Lane, Oldham, in the County of Lancaster,
Spinning Master, 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 bobbins at present in use with ring spinning frames in which the "Rabbeth
spindle" is used, are made parallel or approximately so from end to end, at that part
which receives the yarn as it is spun and wound upon them.
In the course of spinning upon the ring spinning frame the greater quantity of the
yarn upon the bobbin is wound upon an inclined or conical surface formed by the
several layers of yarn one upon the other, hitherto when "gaiting or beginning a
fresh set, the yarn forming the cop bottom is first wound upon the parallel surface
of the bobbin each succeeding layer increasing the thickness until the required number
of layers have been first laid on to raise the lower part of the wound bobbin to the
desired thickness, the filling of the bobbins then proceeds regularly up to the top.
until full. These first layers forming the cop bottom wound upon the smaller diameter
receive less twist and the yarn is consequently weaker and more liable to break than
what is uniformally wound upon the inclined surface afterwards provided.
It is to obviate this chiefly that this invention is designed and to provide a bobbin
which will present an inclined or conical surface to receive the first layer of yarn,
of the same diameter and inclination as each succeeding layer until the bobbin
is full.
It consists essentially in making the bobbin with an inclined or conical shoulder or
- collar at or near the base to receive the first layer of yarn spun or wound upon it.
Referring to the accompanying drawings.
Fig. 1. is an elevation of my improved bobbin and Fig. 2 is a sectional elevation
of same showing in dotted lines the position the yarn will assume upon it.
The bobbin A is made preferably of wood turned down from a solid piece (though
it may be made of other material, such as papier mache, from which bobbins are
made). At the base or lower end it is formed with a conical or inclined shoulder or
collar B. This shoulder tapers or inclines towards the top of the bobbin for a length
equal to that of the lift or chase, and at the base is of diameter equal to the thickness
of the full bobbin. It is preferably flat or square at the base but may be more or less
inclined in the direction of the bottom also if desired.
Although the bobbin is shown with the collar B made or turned out of a solid piece,
it may be made separately in the form of a truncated cone and applied, but I prefer
in making new bobbins to have them solid as-shown but for old or existing bobbins
the collar may be made-separately and applied.
Below the shoulder B, the bobbin is formed to fit the cup of the spindle. This is
preferably done by cutting a groove or slot b round the underside of the conical
collar B leaving the base a of the bobbin to project a short distance beyond. This

page_text: construction I prefer as it protects the base a-the weakest part of the bobbin-from
being damaged by being trodden upon. The groove may however be dispensed
with and the base a project beyond the shoulder for a sufficient distance to engage
with the cup of the spindle.
In spinning, the first layer of yarn at the cop bottom is wound upon the shoulder B
and subsequently each succeeding layer is built one upon the other, gradually filling
up the parallel part of bobbin from the point a¹ to the top. It will be seen that as
each layer of yarn is wound upon a surface of the same inclination the whole cop will
be of equivalent quality throughout.
By the invention I consider I effect a saving by preventing breakage and waste
both in spinning and reeling, I produce a more uniform quality of yarn and at the
same time provide a bobbin that will be stronger and less liable to breakage or damage
than many of those at present in use.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I wish it to be understood that
I am aware that bobbins which revolve at a different rate to the spindles have been
made with collars or shoulders at the bottom and I make no claim therefor but limit
the invention to the hobbin with inclined or conical shoulder as applied to the
Rabbeth or similar spindle in ring spinning frames and I declare that what I
claim is.
1. The use or combination with a ring spinning frame fitted with Rabbeth spindles
of a bobbin having a conical or inclined shoulder at its base in length equal to that
of the lift or chase, and in diameter to that of the full bobbin, substantially as and for
the purposes described.
2. In a bobbin for ring spinning frames the combination with the parallel tubular
sides A of the conical shoulder B and the base a with or without the groove & sub-
stantially as shown and described.
