THOMAS BLACKBURN, of Phoenix Mill, Brighouse, in the County of York, Cotton
Spinner. "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR SECURING
THE ENDS OF BANDS FOR DRIVING THE SPINDLES OF SPINNING OR OTHER
MACHINES."
The first part of this Invention relates to certain improvements in the method of
securing together the ends of bands for driving the spindles of spinning frames or
other machines, described in the Specification of Letters Patent granted to me,
dated February 14th, A.D. 1876, and numbered 606.
The object of this part of the Invention is to preserve the double hook described
in the before-named Specification from cutting the band where the same is hooked
into the loop and strands of the band. This is accomplished in the following
manner-I place a metal eyelet between the strands at the loop end of the band,
and between the strands close to the metal ring, described in the said Speci-
fication. These eyelets are clenched, and thus made secure in the strands of the
band and forms a bush, which gives more bearing surface in the band. The double
hook is passed through these eyelets, and does not cut the strands of the band in
passing over the pullies or spindles. The ends are connected together, as described
in the before-named Specification.
The object of the second part of this Invention is to connect together the ends of
the bands for driving the spindles of spinning frames and other machines in such a
manner that when the band becomes slack on the pullies or spindles the tension can
be increased and regulated so as to drive the machinery at an uniform speed, and to
effect a great saving in time and material over the ordinary method of replacing
new bands for those that have become a little slack. I accomplish this in the
following manner:-The bands are made in the ordinary manner, or on the cable
principle, with a loop at one end, and in lengths to suit the various machines. At
the loop end of the band I secure a metal eyelet, which forms a bush in the band;
D

band. One end of this sliding book is arranged to receive the end of a double hook,
similar to those in ordinary use for driving sewing machines. The band is placed
round the pullies or spindles and stretched tight to the proper length, when the loose
end of the band is untwisted from the end to the before-named sliding hook. The
strands of the band are tied together in a single knot, and the loose ends cut off.
The double hook, which is secured in the eyelet at the looped end of the band, is
then hooked into the sliding hook, and thus forms a swivel coupling, which is
flexible, and will accomodate itself to the curve of the pullies or spindles, and pass
easily round the same, and not cause the pullies or spindles to jump, but will have
a steady motion.
The introduction of the eyelets into the bands is for the purpose of making the
band more durable, and preventing the double hook from cutting the same.
The swivel coupling can also be applied in coupling the ends of the bands together
without the eyelet, as before described.
The sliding hook can also be so arranged to connect the ends of the band together,
without the use of the before-named double hook, but I prefer using the two hooks
in conjunction with each other, the same being more flexible and better adapted to
pass round the small curves of the spindles.
