MENTS IN THE CONSTRUCTION OF APPARATUS USED FOR DOUBLING OR TWINING

! 1'.
This invention relates principally to that class of apparatus (used for doubling
or twining yarns or threads) known as "mule twiners" or "doublers" the object
of the said invention being to obtain an extended drag or tension upon the yarns
or threads whilst twining or doubling them, so as to obtain a more evenly twisted
or doubled yarn, and a stronger yarn than heretofore in proportion to the weight
of material employed.
The improvement consists in the peculiar formation of the thread board on the
top of the carriage over which the threads to, be twined or doubled. pass on their
way from the creel to the twining or doubling spindles. (I make the upper surface
of this board in a considerably curved form having a rise of (say). two and a half
to three inches or more in the centre in a board of 'six to six and a half inches in
width and by this means I obtain an additional fractional surface or drag without
increasing the width of the board itself, and an increasing tension on the yarn.
I prefer to make this curve of an elliptical or parabolic form instead of: part of a
regular curve or circle and by these means I get an increasing tension on the yarn
as the twining or doubling proceeds and the twist is much more even and 'regular
than heretofore and consequently the twined or doubled yarn is stronger in pro-
portion to its weight than when irregularly twisted as is frequently the case with
the twiners now in use.

This invention relates principally to that class of apparatus (used for doubling
or twining yarns or threads) known as "mule twiners" or "doublers" the object
of the invention being .to obtain an extended drag or tension upon the yarns or
threads without any increase of strain of breakage whilst twining or doubling them,
so as to obtain a more evenly twisted or doubled yarn and a stronger yarn than
heretofore in proportion to the weight of the material employed.
Such being the nature and object of my said invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect and in order that the same may be clearly understood
I have annexed hereunto a drawing illustrative thereof, and have marked the
same with letters of reference corresponding with those in the following explanation
thereof.
The annexed drawing represents a section of the thread board of a
twiner" or "doubler" with the creel attached.

The improvement consists principally in the peculiar formation of the thread
board on the top of the carriage over which the threads to be twined or doubled
pass on their way from the creel a, a to the twining or doubling spindles.
The thread board is in two parts b, b and c, c as usual and I make the upper
surface of the part b,b in a considerably curved form having a rise of (say) two
and a half to three inches or more in the centre in a board of six to six and a half
inches in width. The part c, c is also made with a considerable curve on the upper
surface as shown on the drawing, and by these means I obtain an additional
frictional surface or drag without increasing the width of the board itself, and an
increasing tension on the yarn. I prefer to make this curve of an elliptical or
parabolic form (or it may be part of a regular curve or circle) and I thus get an
increased tension on the yarn during the twining or doubling process with reduced
breakage, and the twist is much more evenly and regularly distributed along
the thread than heretofore and consequently the twined or doubled yarn is
stronger in proportion to its weight than when irregularly twisted as is frequently
the case with the twiners now in use.
The usual earthenware weights on the part c, c of the thread board are also
dispensed with.
Instead of fixing the rail d, d which carries the hooks e, e (under which the
threads pass) onto brackets, as usual I mount them in notches in the ends of
levers, which are adjustable on a rod or shaft g, g. At one end of this rod or
shaft is fixed a handle or lever h, h by means of which the height of the hooks is
adjusted as shown by the dotted lines according to the count of yarn being
doubled or the drag or tension required. This lever is fixed when adjusted by
passing a pin through it, and through one of the holes in the curved bracket i, i
and thus any requisite amount of tension can be given to the yarn.
Having now described the nature and object of my said invention together with
the manner in which the same is to be or may be performed or carried into
practical effect I wish it to be understood that I claim as my invention the
improvements hereinbefore described and represented on the drawing annexed

page_text: whereby an extended drag or tension is obtained upon the yarns or threads whilst
being twined or doubled with a reduced breakage and more evenly distributed
twist than heretofore without increasing the width of the thread board substantially
in the manner and for the purposes herein before set forth.
In witness whereof I the said William Henry Jones have hereunto set my hand.
