I CARL SIPMAN of St. Mary Gate in the town and County Town of Nottingham,
Silk Merchant, do hereby declare the nature of this invention to be as follows:-
:-
Instead of placing the guide bar in front of the spindles, which carry the bobbins or
reels, I place it over the driving shaft with the guides in a horizontal position, so as to
guide the threads on to the bobbins from above.
This enables me in double sided machinery to make one guide bar do for both sides,
by fixing guides horizontally on both sides of the guide bar, employing only one
shaft with driving wheels attached, each wheel turning two spindles, one on each side
of the frame.
This arrangement also enables me to fix in doubling machinery the leavers, intended
for stopping the spindle in case of breakage of the thread, above the spindle.
For regulating the tension and keeping the leaver lifted up, I employ a fork, through
which the thread runs.
In order to keep the thread, in its passage from the hank to the bobbin or reel, in
its proper place, I run it between two wires stretched across the frame.
By these arrangements I simplify the construction of winding and doubling
machinery and effect a saving both in space and in cost of construction.

An Improvement in Winding and Doubling Mechanism.
I CARL SIPMAN, British subject, of St. Mary Gate in the Town and County Town
of Nottingham, Silk Merchant do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
==
The object of my invention is to simplify the construction of winding and
doubling mechanism and thereby reducing the cost of construction and at the same
time increasing production.
According to my invention, instead of placing the guide or traverse bar in front
the receiving bobbins, I place it over the driving shaft with the guides projecting in an
horizontal position, so as to guide the thread on to the bobbins or reels from above.
This arrangement enables me in double sided winding or doubling machinery to make
one traverse bar do for both sides by fixing guides horizontally on both sides of the
traverse bar employing only one shaft with driving wheels attached for both sides of
the machine, each wheel turning two spindles, one on each side of the machine.
In order to keep the thread in its passage from the hank or delivery bobbins on to
the receiving bobbin in its proper place, I run it over a wire or wires stretched across
the frame or attached to a bar at a suitable height. When the silk or yarn is wound
from swifts, I use wires bent on both ends, so as to fit the spokes, being moveable so as
to adjust themselves to the length of the hank.
For regulating the tension I run the thread through a fork or through an eye fixed
to a spring.
The ination is il

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1) The construction and arrangement of the traverse bar with guides horizontally
fixed to it, as described.
2) The arrangement for adjusting the tension as described.
3) The general arrangement for drawing off the thread from the hank and guiding
it on to the receiving bobbins as described.
