PROVISIONAL SPECIFICATION left by the said Joseph Smith at the
Office of the Commissioners of Patents, with his Petition, on the
29th May 1869.
I, JOSEPH SMITH, of Loth, in the Kingdom of Belgium, Worsted
Spinner, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR HOLDING THE BOBBINS ON THE TUBES OR SPINDLES OF
SPINNING AND CAP FRAMES, ALSO FOR REGULATING THE DRAG OF THE THREAD
PASSING ON TO THE BOBBINS OF COMMON SPINNING FRAMES," to be as follows:--
The object of my Invention is to hold the bobbin on the tube or
spindle in spinning and cap frames with varying degrees of pressure
according to the velocity at which the tube or spindle is travelling.
[Price Sd.]

page_text: The Invention consists in fitting two or more springs in recesses
in the stem of the tube or spindle employed in spinning and cap frames.
These springs form a portion of the circumference of the tube and act
upon the inside of the bobbin and hold it thereon by the centrifugal
action of the tube or spindle in revolving.
SPECIFICATION in pursuance of the conditions of the Letters l'atent,
filed by the said Joseph Smith in the Great Seal l'atent Office on
the 29th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPHI
SMITH, of Loth, in the Kingdom of Belgium, Worsted Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of May, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Smith, Her special licence
that I, the said Joseph Smith, my executors, administrators, and
assigns, or such others as 1, the said Joseph Smith, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR HOLDING THE BOBBIN ON THE TUBES OR SPINDLES OF SPINNING AND
CAP FRAMES, ALSO FOR REGULATING THE DRAG OF THE THREAD PASSING ON TO THE
BOBBINS OF COMMON SPINNING FRAMES," upon the condition (amongst others)
that. I, the said Joseph Smith, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, aud in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six

page_text: calendar months next and immediately after the date of the said LRCIS
Patent.
NOW KNOW YE, that I, the said Joseph Smith, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by.
the following statement thereof; reference being 'had to the Drawings
hereunto annexed, that is to say :-
The object of my Invention is to hold the bobbin on the tube or
spindle in spinning and cap frames with varying degrees of pressure
according to the velocity at which the tube or spindle is travelling.
The Invention consists in fitting two or more springs in recesses
in the stem of the tube or spindle employed in spinning and cap frames.
These springs form a portion of the circumference of the tube and act
upon the inside of the bobbin, and hold it thereon by the centrifugal
action of the tube or spindle in revolving.
In some cases the springs may be fitted to a washer or other appliance
on the lifter of common spinning frames in order to regulate the drag
of the thread passing on to the bobbin.
The accompanying Drawings represent the manner in which I prefer
to carry my Invention into effect.
Figure 1 is an external view of a tube which is ordinarily in use
with my apparatus or appliances aflixed thereto; and Figure 2, a
sectional elevation of the same tube taken at right angles to Figure 1
to shew the Invention more clearly.
of
In Figure 2 I have shown a bobbin on the tube with the springs
out of action or in the position they would occupy when the tube is
not revolving, while in Figure 3 I have shewn them in the position
they would occupy when the tube is rotating, and according to the
speed at which the tube may be travelling so would the pressure
the springs be against the inside of the bobbin to ensure its turning
therewith. At the same time should extra strain be put upon the.
thread as it is being wound on, the springs would allow the bobbin
to slip a little, by which means the breaking of the thread is entirely
obviated.
In the Drawings a, a, represent the springs which are fitted into
recesses formed in the sides of the tube b. The springs are bevilled
chamfered, or rounded off at their edges so that they conform to the

page_text: .
circular shape of the tube and admit of the bobbin c being placed
on or removed from the tube with facility. The lower end of the
tube carries a
whorl " or pulley d, for a band to pass round and
cause it to turn on motion being given by mechanism of any kind.
The springs may be soldered or rivetted at their upper ends in the
recesses of the tube while their lower ends are left free to be thrown
outwards by centrifugal force.
In the Figures I have shown the tube as being fitted with two springs
only, but I do not confine myself to that number, as three or more may
be attached if required for the efficient working of the bobbin. Neither
do confine myself to the employment of straight springs as represented
in the Drawings, as spiral or helical springs may be fitted in a similar
manner and for the same purpose.
In some cases the springs may be fitted in recesses formed in the
spindle itself, or they may be fitted on washers or other similar appliance,
in which case I prefer that the washers should rest upon the lifter
bar or some apparatus in connection therewith, so that the drag on
the thread passing on to the bobbin may be regulated with certainty.
And having now described the nature of my said Invention and
in what manner the same is to be performed, 1 declare that I claim,-
Firstly. The employment of springs upon the tubes or spindles of
spinning and cap frames which are thrown outwards by centrifugal
action or force for holding the bobbin and regulating the drag of the
thread in the manner herein-before described and shewn in the
Drawings.
Secondly. The modified arrangements or modes of fitting the springs
upon spinning and cap frames for the purposes herein-before described.
In witness whereof, I, the said Joseph Smith, have hereunto
set my hand and scal, this Twenty-sixth day of November, in
the year of our Lord One thousand eight hundred and sixty-
nine.
JOSEPH SMITH. (L.S.)
