THE SPINDLES OF SPINNING FRAMES OR OTHER MACHINES."
This Invention relates to certain improvements in the method of securing the
The
ends of bands for driving the spindles of spinning frames or other machines.
methods of securing the ends of bands made of cotton or other material for driving
machinery are various, such as splicing the ends together, which causes one part of
the band at the splice to be thicker than the rest; another method is to make the
band with a loop at each end, and secure the ends together by means of a double
hook. The difficulty of making bands of this description is of a very tedious
nature, in consequence of the many varying distances between the centre of the
spindles and the centre of the cylinder; one of the loops at the end of this last
named band is thicker than the other part of the band in consequence of the
strands of the band being turned back and spliced in order to form the loop; when
the machinery is in motion the spliced portion when passing round the spindle
gives a jerking motion to the same, causing the yarn to be uneven in thickness.
The object of my Invention is to connect the ends of bands used for driving
spinning and doubling frames or other machinery together in such a manner that
the irregularities in thickness at the ends where jointed together is reduced to a
minimum, in order to give the spindle an uniform speed.
I accomplish my object in the following manner:- -The bands are made in the
ordinary manner with a loop at one end, and of such lengths as will suit the various
machines, when the band is placed round the cylinder or pulley and the spindles
and stretch tight, I couple the ends together by means of a double hook similar to
those in ordinary use for coupling the leather belts for driving sewing machines;

page_text: one end of the said hook is placed through the loop end of the band, and the other
end of the hook is put between the strands of the band, making the band the
proper length for driving the spindles; the strands at the loose end of the band are
prevented from untwisting and the double hook kept in the proper position by
placing a metal ring at as short a distance as practicable from the aforesaid hook
and firmly securing the same to the band, or in place of the ring to wrap some
waxed yarn round tightly, then cutting off the surplus end of the band near to the
said metal ring or waxed yarn; the band is then ready for driving the machinery,
which will be driven at a more uniform speed than heretofore, in consequence of the
regularity of the thickness of the band at the junction of the two ends.
I wish it to be distinctly understood that what I claim is, the method of securing
the loose ends of driving bands by means of a metal ring or waxed yarn, in order
that the strands will not untwist, and that the ends may be secured together by
means of a double hook or S link.

"IMPROVEMENTS IN THE METHOD OF SECURING THE ENDS OF BANDS FOR DRIVING
THE SPINDLES OF SPINNING FRAMES OR OTHER MACHINES."
This Invention relates to certain improvements in the method of securing the
ends of bands for driving the spindles of spinning frames or other machines. The
methods of securing the ends of bands made of cotton or other material for driving
machinery are various, such as splicing the ends together, which cause one part of
the band at the splice to be thicker than the rest; another method is to make the
band with a loop at each end, and secure the ends together by means of a double.
hook. The difficulty of making bands of this description is of a very tedious
nature, in consequence of the many varying distances between the centre of the
spindles and the centre of the cylinder; one of the loops at the end of this last
named band is thicker than the other part of the band, in consequence of the strands
of the band being turned back and spliced in order to form the loop; when the
machinery is in motion the spliced portion when passing round the spindle gives a
jerking motion to the same, causing the yarn to be uneven in thickness.
The object of my Invention is to connect the ends of the bands used for driving
spinning and doubling frames or other machinery together in such a manner that
the irregularities in thickness at the ends where jointed together is reduced to a
minimum, in order to prevent as much as practicable the jerking motion of the
spindle caused by the uneven thickness of the band at the splicing or junction of
the ends.
I accomplish my object in the following manner:-The bands are made in the
ordinary manner with a loop at one end, and of such lengths as will suit the various.
machines when the band is placed round the cylinder and spindles and strectched
tight. I couple the ends together by means of a double hook similar to those in
ordinary use for coupling the leather belts for driving sewing machines; one end of
the said hook is placed through the loop end of the band, and the other end of the
hook is put between the strands of the band at the other or loose end, making the
band the proper length for driving the spindles; the strands at the loose end of the
band are prevented from untwisting and the double hook kept in the proper
position by placing a metal ring at as short a distance as practicable from the
aforesaid hook; by nipping the circumference of the ring with a pair of pliers or other
instrument the same is compressed and firmly grips the band, thus preventing the
strands from untwisting, and the double hook securely connects the ends together; or

as the waxed yarn is not so durable, and is a more bulky, clumbsy junction; then
cut off the surplus end of the band near to the said metal ring or waxed yarn; the
band is ready for driving the machinery, which will be driven at a more uniform
speed than heretofore, in consequence of the regularity of the thickness of the band
at the junction of the two ends.
I wish it to be distinctly understood that what I claim is, the method of securing
the loose ends of the driving bands by means of a metal ring placed on the loose end
of the band and compressed thereon, in order to prevent the strands from untwisting
and to keep the double or S hook in its proper position, or to use a waxed yarn for
the same purpose as the metal ring.
DESCRIPTION OF DRAWINGS.
Like parts are indicated by like letters and figures.
Fig. 1 shews my improved metal ring A compressed on the loose end of the
band B; in Fig. 2 C is the ordinary loop end of the band.
Fig. 3 is a view of my improved metal ring A.; Fig. 4 is a plan of the same.
Figs. 5 and 6 are views of the double hook E.
Fig. 7 shews the end of the bands joined together by means of the double hook E,
one end of which is hooked into the loop end C of the band and the other is hooked
into the strand of the band, as close as practicable to my improved metal ring A,
which prevents the strands from untwisting.
