COMPLETE SPECIFICATION.
A Doubling Reel for Twining or Doubling Yarn, and Delivering
it in Skeins.
I, GUSTAV SALEFSKY, Junior, of 23p Reinickendorfer Strasse, Berlin, Manager
of a Spinning Mill, 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 subject of this invention is a machine adapted to twine or double yarn
direct from the cops as supplied by the selfactor, and then to reel such yarn, so
that it is delivered from the machine in skeins ready for immediate transport or
shipment; it being unnecessary to either wind the yarn on spools before, or to reel
it after, the twining or doubling process.
The subject of the invention is illustrated in the accompanying drawings, in
which
Figure 1, is a front view, and
Figure 2, a side elevation of one individual apparatus of the class herein
described, any suitable number of which, may be arranged side by side,
Figure 3, is a section of the upper part of the spool, also shewing the thread-
tension device, which is supposed to have dropped to its lower position, and
Figure 4, represents the reels supposed to have been turned at 180° to Figure 1,
i.e., to the position in which the spun material is ready for removal from such
reels.
The cops, of which there may be two, three or any desired number, are disposed
at (e), the yarn passing from such cops, over transversely extending guide rods (w),
and through an eye (p) adaped to exercise the requisite pressure or tension on the
thread and provided in the lever (f). Thence the thread passes over the roller of
a suitable measuring instrument, after which it is conducted through the hollow
shaft or spindle of a vertical flyer (a), during which passage it is twined and finally
wound upon two reels (i), (). The flyer is driven from the pulley (b) through the
medium of an endless cord passed over the said pulley and a grooved roller (c), and
it consists of a rectangular frame bent or contracted at the top and bottom and
terminating in pivots or journals for the reception of the shaft. Below, in a step-
bearing (4), the central pivot is arranged, while at the top, the shaft is hollow, and
is held in a collar-bearing provided with the spool frame (=).
The reels (i), (i) are driven in the following manner:
A toothed wheel (1) engages or gears with a stationary ring (k) threaded
internally. This arrangement is a kinematic reversion of the well known worm
and worm-wheel gearing, the only difference being, indeed, that the worm instead
of being threaded externally, offers an internal screw thread for engagement, or in
other words, forms a screw-nut. The wheel (1) has to be arranged eccentrically to
the revolving shaft or spindle, seeing that it is required to remain in gear during
the rotation of the flyer; and to enable it to be so situated the said spindle is
slightly cranked. Whenever the flyer is set in motion, such motion is directly
imparted to the wheel (1) and, through the medium of the toothed wheels (m), (n),
(o), (g), is transmitted to the lower wheel (i).
For the automatic arrest of the mechanism a friction-clutch (s), capable of
being disengaged when required, is provided, the upper half of the clutch being
firmly connected with the hollow shaft or spindle of the flyer, while the lower half

page_text: joins the grooved cord pulley (c). A lever (r), fitted with a balancing weight, in
the normal condition keeps the friction-clutch in gear, so that the cord pulley may
convey its own rotary motion to the flyer. In the event, however, of the thread
breaking, the thread-tension eye (p), together with the lever (f), descends, and in
so doing depresses the left arm of the lever (r), thereby disengaging the coupling
or clutch. By such means the flyer is instantly arrested, independently of the
grooved pulley or roller, which continues to revolve idle.
When a predetermined number of yards or metres of yarn has been wound or
reeled, a cam or tappet (u¹), projecting from the wheel (u), of the measuring
instrument engages with the arm (t), fixed on the lever (r) which it depresses,
thereby throwing the clutch-coupling (s) out of gear.
In order to remove the finished skeins, the reel spindle may be removed from the
flyer by turning. For this purpose, there is provided on the left side of the flyer
a movable sleeve (r) (Figure 1), wherein one of the bearings for each of the reel
spindles (i) (i) are formed. A pin, adapted to slide in a slot, with which the said
sleeve is provided, secures the sleeve in its position, while the lower reel spindle
is retained in its position, so that the toothed wheel (9) cannot get out of gear.
The spindles of the reels revolve in bearings in which they are held by pointed
journals, such bearings being formed, on one side, in the sleeve (1), and on the
other side in the rod or bar of the flyer (a), or the flyer screw (y).
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:
The doubling reels for combining or twining together any desired number of
threads provided with an arrangement in which the cops remain stationary in the
frame, whilst the reels rotate about the axis of the doubled or twined yarn in
course of formation.
