an Invention of "IMPROVEMENTS IN OR CONNECTED WITH SPINNING-
MACHINERY."
PROVISIONAL SPECIFICATION left by the said Robert Erskine Osborne,

of Patents on the 13th November, 1880. -
ROBERT ERSKINE OSBORNE, ARTHUR PATON MATHEWSON, & JOHN GUILD,
all of Dundee, in the County of Forfar, North Britain. "IMPROVEMENTS IN OR
CONNECTED WITH SPINNING MACHINERY."
This Invention relates to certain improvements in spinning machinery, and
particularly connected with the temper, tension, or friction bands employed to
regulate the strain on the winding thread by pressure on the turning bobbins or
forming a drag or brake for them.
The bands hitherto used for this purpose have been made of leather thongs or
hempen cords heavily weighted to apply the requisite friction, and the bands are
liable to rapid wear and sudden breakage, necessitating the stoppage of the
winding machinery to replace them. By the present improvements such objections
are overcome, and the weights required for the bands being much lighter than
hitherto a great saving is also effected in the power required to operate the
winding frames and the reciprocating bobbin plates which support those
weights.
The Invention consists in forming the temper or tension bands of iron, steel, or
brass wire, preferably slightly curved to bear with the concave surface of each on
the lower flange of its bobbin, and lying as usual across the upper surface of the
bobbin plato or rail. The wires or bands are formed with a loop or eye at each
end, and are connected at the back or inner side to an adjustable screw bolt, or
stud fitted in the back edge of the bobbin plate. The outer end of each wire or
band has a cord, chain, or flexible wire connected to it passing over the front
edge of the bobbin plate and having a small weight attached to its end.
When the improved temper bands are put into action the curve wire is brought
into contact with the flange of the bobbin, and the weighted cord or chain
suspended over the front edge of the bobbin plate is placed in one of the usual
rn

page_text: notches cut in a flange or rib on the front of the plate in such a position as to
cause the curved wire to bear with the desired pressure against the bobbin. And
when a bobbin is to be removed the weighted cord and band are shifted back in the
usual way.
When any part of the wire band becomes worn by friction of the revolving
bobbin the adjusting bolt or stud at the back is screwed up or loosened to bring
another part of the wire to bear on the bobbin when in action, and the band
may thus be worn through the greater part of its length before requiring
renewal.
The metal or wire part of the improved temper bands may be made round or 1
half round to suit the usual groove on the flange of the bobbin, or any other
convenient form of cross section may be adopted, such as triangular, diamond shape,
or even flat.

ROBERT ERSKINE OSBORNE, ARTHUR PATON MATHEWSON, and JOHN GUILD,
all of Dundee, in the County of Forfar, North Britain. "IMPROVEMENTS IN OR
CONNECTED WITH SPINNING MACHINERY."
Our said Invention relates to certain improvements in spinning machinery, and
particularly connected with the temper, tension, or friction bands employed to
regulate the strain on the winding thread by pressure on the turning bobbins or
forming a drag or brake for them.
The bands hitherto used for this purpose have been inade of leather thongs or
hempen cords, heavily weighted, to apply the requisite friction, and these bands are
liable to rapid wear and sudden breakage, necessitating the stoppage of the winding
machinery to replace them. By the present improvements such objections are
overcoine, and the weights required for the bands being much lighter than
hitherto a great saving is also effected in the power required to operate the
spinning and winding frames and the reciprocating bobbin plates which support
those weights.
And in order that our said Invention and the manner of performing the same
may be fully understood, we have hereunto appended for that purpose a Sheet of
explanatory Drawings representing our improvements, which we shall now proceed
to describe. In these Drawings the same reference letters are used to mark the
same parts where repeated.
'
Figuro 1 of the Drawings is a vertical section of part of a spinning frame or
machine; Figure 2 is a plan; and Figuro 3 is a front elevation of the same,
showing two spindles and bobbins with our improved tonsion or temper bands
applied thereto.
Referring to these Drawings our said Invention consists in forming the temper
or tension bands A of iron, steel, or brass wire, preferably slightly curved, as shown
in the plan, Figure 2, to bear with the concavo side or surface of each wire A on
the lower flange of its bobbin B, and lying as usual across the upper surface of the
bobbin plate or rail C. The wires or bands are formed with a loop or eye a, a, at
each end, and are connected at the back or inner side to a screw bolt or stud A'
fitted in or passing through the back edge C¹ of the bobbin plate C, and which is
adjustable by means of screw nuts A². The outer loop or end a.of each wire or
band A has a cord, chain, or flexible wire D connected to it, passing over the
front edge C of the bobbin plate, and having a small weight D' attached to its
end..
When the improved temper bands are put into action the curved wire A is
brought into contact with the lower flange B¹ of the bobbin, and the weighted cord
or chain D suspended over the front edge of the bobbin plate is placed in one of
the usual notches c cut in the flange or rib C on the front of the plate C in such a
position as to cause the curved wire A to bear with the desired pressure against
the flange B¹ of the bobbin B; and when a bobbin is to bo removed the weighted
cord D and band A are shifted back in the usual way to take the wire A out of
contact with the bobbin.
When any part of the wire band A becomes worn by friction of the revolving
bobbin B, the adjusting bolt or stud A' at the back is screwed up or loosened
outwards or inwards to bring different parts of the wire A to bear on the
bobbin B, B', when in action, and the band may thus be worn through the greater
part of its length before requiring renewal.
The metal or wire part A of the improved temper bands may be made round
or half-round to suit the usual groove on the flange B¹ of the bobbin, or any

page_text: other convenient form of cross section may be adopted, such as triangular, diamond
shape, or even flat.
Having thus particularly described our said Invention, and the manner of
performing the same, we desire it to be understood that what we believe to be
novel and original, and therefore claim as the Invention secured to us by the
hereinbefore in part recited Letters Patent is, the construction and use of metallic
wire tension or temper bands for holding the bobbins in spinning machinery,
substantially as herein described in reference to the accompanying Drawings.
In witness whereof, we, the said Robert Erskine Osborne, the said Arthur
Paton Mathewson, and the said John Guild, have hereunto sot our hands
and seals, this Eleventh day of May, in the year of our Lord One thousand
eight hundred and eighty one.
