CARL SIPMAN, of Kaye's Walk, in the Town and County Town of Nottingham,
Silk Merchant. "AN IMPROVEMENT IN DOUBLING, TWISTING, AND REELING
MECHANISM WHEREBY THE USUAL SEPARATE OPERATIONS FOR THOSE PURPOSES ARE
DISPENSED WITH.
"
The object of this Invention is a certain improvement in mechanism to be
employed in doubling and twisting silk, wool, cotton, and other fibrous materials
and threads of other descriptions in and by the same apparatus, instead of by
separate apparatus and at distinct operations, as is now the case.
According to my Invention I dispense with the usual spindle which carries the
bobbin, and instead thereof I employ a tubular collar, to which I attach a flyer or
flyers, the thread or other fibre passing through direct from the bobbins or cops to
the reel or the taking up bobbin.
The collar is capable of producing twists either from one or from both ends
simultaneously.
By this Invention the several operations of doubling, twisting, redoubling, second
twisting, and reeling are effected in the one apparatus, and simultaneously.
Instead of driving the collar or collars and corresponding part of the reel from
the usual drum I purpose employing a wheel fixed to the shaft, which by being
thrown out of gear any collar or set of collars with the corresponding part of the
reel and bobbins can be stopped in cases of any thread or threads breaking, or for
oiling purposes.

This Invention relates to a tubular rotatory twister for attachment to doubling,
twisting, and reeling mechanism whereby the usual separate operations for those
purposes are dispensed with.
The tubular rotatory twister is illustrated in the annexed Drawings, Figure 1
being an elevation, Figure 2 a section of same, and Figure 3 a plan.
A is a tube; B, the body, this having one or two annular grooves C, C, for the
reception of gut or other bands by which the twister can be rotated; D is a flyer,
through the eye E of which the thread or threads to be twisted is or are passed,
and then led through the tube A, the thread or threads bearing upon a wire a
fitted across the tubular portion to keep it or them in the centre of the tube, and to
prevent friction the thread is led therefrom to a draw off bobbin or reel; F is a
second flyer on the same apparatus, through the eye G of which the twisted thread
may be passed.
Figure 4 illustrates the application of my Invention to a portion of a spinning
frame. The thread H from the cop J passes through a funnel shaped opening in
the bar K, then between two tension rollers L, L, to the eye E of the flyer D, and
through the tube A to a draw off bobbin, the twister being supported and guided
by the two bars M, N.
Figure 5 is a similar view of a portion of a spinning frame showing two threads
from separate bobbins or cops J, J, to the eye E of the twister for the doubling
operation, the doubled thread passing through the tubular portion of the twister to
the draw off reeling bobbin, as before explained.
In order to combine the process of gassing the thread with the process of reeling
or winding the same on bobbins, I fix between every two tubular collars, as repre-
sented at Figure 6, a gas burner so arranged that the flyers just pass underneath
the flame and remain cool, whereas the thread or threads are several times and at a
rapid speed carried through the flame, and have the ends of the two loose fibres
burnt off whilst being drawn through the rotating tube by the reel or the taking
up bobbins, the speed of the latter being so adjusted as to prevent injury to the
thread in passing through the flame.
The method of doubling two or any number of threads is shown at Figure 7,
which illustrates a section of a doubling frame, the top part being an exact counter
part of the bottom part (reversed), so as to bring the shafts S, S, which give motion
to the taking up bobbins C, C, into the middle of the frame, and enabling the
driving of the shafts by one gearing, dispensing at the same time with one slide
rod, and thus considerably simplifying the mechanism. A, A, are the bobbins con-
taining the single threads for doubling. In the Drawing six threads are run
together, but any number more or less can be doubled in the same way. Only the
heads of the bobbins are indicated in the Drawing, each having a narrow stripe
painted across it, so as to attract at once the notice of the attendant in case the
thread should break or run off. Little rollers either of wood, brass, or any other
suitable material are employed at B¹. Three threads are run together, and having
passed over B the six threads are united at B3, round which they travel, and where
the tension is regulated so that they pass evenly on to the taking up bobbins C. In
case it should be requisite that any twist be imparted, a tubular collar may be sub-
stituted for the roller B³. The taking up bobbins C, C, are fastened to the shaft S

page_text: by a small key K, which when withdrawn in case of the breakage of a thread
causes the particular bobbin to remain stationary, whilst all the other bobbins
continue to take up.
When doffing becomes necessary the shaft, which is constructed in separate
sections, takes out in short pieces, and after the keys are removed the full bobbins
slip off, and are replaced by empty ones.
Having now described the nature of my said Invention, and in what manner the
same is to be performed, I declare that I claim,—
The construction, arrangement, and employment of the tubular collar with flyer
or flyers attached, substantially as at Figures 1, 2, 3, 4, 5, and 6 of the annexed
Drawings, for the purposes described.
Secondly. I claim the arrangement of combining the process of gassing with
reeling or winding, as shown at Figure 6 of the annexed Drawings, and as
described.
Thirdly. The general arrangement for doubling, and the method of fastening the
taking up bobbins to the bobbin shaft, as described.
In witness whereof, I, the said Carl Sipman, have hereunto set my hand and
seal, this Thirtieth day of April, in the year of our Lord One thousand
eight hundred and eighty.
