PROVISIONAL SPECIFICATION.
Improvements in Reels or Holders for Skeins or Hanks of Yarn.
I, HEINRICH SCHWARZENBACH, of Langnau, a/A, Switzerland, Mechanical Wood-
ware Manufacturer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide yarn-reels or the like with radially
adjustable arms that are acted upon by spring pressure which has a tendency to
thrust the reel arms outwards. The spring is mounted in the hub, and can, after
loosening a suitable device by means of which the arms are fixed in their position
for the time being, be brought into action in such a manner that it shifts the
arms radially outwards.
In the accompanying drawing, there is shown, by way of example, one form in
which the arms have teeth which engage in a central pinion so that, by the rotation
of the pinion, under the action of the spring, the arms are simultaneously auto-
matically shifted outwards, and by rotating by hand in the opposite direction, they
are shifted inwards.

nut e.
The arms a of the reel are toothed and carried in grooves 6 of the hub c. In
the latter there is located a toothed-pinion or bolt d, in such a manner that the
teeth of all the arms engage in the teeth of the pinion. The spring casing c
is detachably connected with the casing c so that the spiral spring f can be placed
therein. This spring is fastened on the one hand at to the axle of the pinion d
and on the other hand at at the interior of the spring casing. The axle of the
pinion is provided at the other end with a screw thread d¹, on which is placed a
Upon the axle of the pinion there is arranged a ring g which serves as a
supporting disc for the nut e so that on screwing up the said nut e upon the sup-
porting disc g, the latter is pressed upon the casing c. In this clamped position,
the pinion axle with nut and casing are firmly connected together in such a
manner that the spring f cannot act. If, on the other hand, the nut e is
unscrewed or loosened, then, assuming that the spring f has been previously given
the necessary tension by rotating the projecting part of the pinion axle, the
pinion d, under the pressure of the tension of the spring, rotates within the hubo
and the arms are, by the toothed pinion, shifted radially outwards till the spring
tension ceases to act, or till possibly the tension of the yarn that is on the reel
counteracts the expansion force.
In use, the arms will be adjusted to a comparatively small radius and fixed by
means of the nut e. Then as soon as the yarn is on the reel, the arms are allowed
to expand under the elastic spring-pressure to a certain limit, whilst being
capable of yielding inwards elastically. In order to prevent the arms from being
brought quite out by means of the pinion when the reel is empty on possible

Improvements in Reels or Holders for Skeins or Hanks of Yarn.
I, HEINRICH SCHWARZENBACH, of Langnau, a/A, Switzerland, Mechanical Wood-
ware Manufacturer, 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:-
A varn-reel according to this invention is provided with arms that can all be
automatically and simultaneously moved outwards by means of a single spring,
which is mounted in the hub of the reel.
In the drawings filed with my Provisional Specification there is shown an
example of such a reel in which the arms have teeth which engage in a central
pinion so that, by the rotation of the pinion, under the action of the spring, the
arms are simultaneously and automatically shifted outwards, and by rotating by
hand in the opposite direction, they are shifted inwards.
Fig. 1 shows the reel in side view:
Fig. 2 shows the middle portion thereof, to a larger scale, and
Fig. 3 is a corresponding front elevation after removal of the arms;
Fig. 4 is a longitudinal section corresponding to Fig. 3; and
Fig. 5 is an elevation of the spring casing taken from within.
The arms a of the reel are toothed and carried in slots b in the hub c. In the
latter there is located a toothed pinion d, which engages with the teeth of all the
arms. The spring casing c¹ is detachably connected with the hub c, in any con-
venient manner, as by screws, so that the spiral spring f can be placed therein.
This spring is fastened on the one hand at d to the axle of the pinion d, and,
on the other hand, at to the interior of the spring casing. The axle of the
pinion is provided at the other end with a screw thread d¹, on which is placed a
.nut e. On the axle of the pinion there is also placed a ring g, which serves as a
washer for the nut e, so that on screwing up the said nut e against the washer g,
the washer is pressed against the casing c. In this clamped position, the pinion
axle, the nut, and the casing are firmly connected together in such a manner that
the spring cannot act. If, on the other hand, the nut e is unscrewed or
loosened, then, if the spring f has been previously given the necessary tension by
rotating the projecting part do of the pinion axle, the pinion d, under the action
of the tension of the spring, rotates within the casing c¹, and the arms are shifted
radially outwards by the toothed pinion till the spring tension ceases to act, or, it
may be, till the tension of the yarn that is on the reel counteracts the expansive
force.
In use, the arms are adjusted to a comparatively small radius and fixed by
means of the nut e. Then, as soon as the yarn is on the reel, the arms are allowed
to expand under the elastic spring-pressure to a certain limit, whilst being capable
of vielding inwards elastically.
In order to prevent the arms from being brought quite out by means of the
pinion and consequently coming out of engagement, when the reel is empty and

page_text: the nut is loose, a stop or projection aº is, for example, put on one of the arms, as
shown in Fig. 1.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A yarn reel in which all the arms can be automatically and simultaneously
moved outwards by a single spring contained in the hub of the reel.
2. A yarn reel whose arms can be automatically moved outwards by a spiral spring
and are provided with teeth engaging with a toothed wheel which is arranged cen-
trally in the hub and engaged by the said spiral spring causing the shifting, and
which can be fixed by means of a nut arranged on the axle of the toothed wheel.
3. A varn reel constructed, arranged, and operating as herein before described
with reference to and shown in the drawings filed with my Provisional Specifica-
tion.
