TRAVELER
William Wesley Bassett, Pawtucket, R. I., assign
or to A. B. Carter, Incorporated, Gastonia, N. 0.,
a corporation of North Carolina
Application April 10, 1937, Serial No. 136,100
4 Claims. (Cl. 118-61)
This invention relates to ring travelers for
spinning machines.
Ring travelers when in operation on a spinning
machine travel at a very fast rate of speed around
5 the ring and when so traveling the traveler ?oats
or has practically no contact with the ring.
Various traveler cross-sections have been pro-
posed and used, such for instance as round, flat
and half-oval, that is oval or curved on one side
10 and ?at on the other.
This invention has for its salient object to
provide a traveler so designed as to cross-section
as to reduce the friction of the yarn on the traveler to a minimum.
15
Another object of the invention is to provide
a. traveler having a cross-section so designed as
to reduce to a minimum the air resistance on the
traveler.
Another object of the invention is to provide
The yarn Y approaches the traveler from an
angle and engages one of the surfaces 20 or 25
substantially on a tangent and passes around this
surface and leaves the surface also substantially
on a tangent. Therefore there is a minimum "
amount of frictional engagement between the
yarn and the traveler. Furthermore due to the
shape of the cross-section illustrated in Fig. 2
it will be evident that the air resistance to the
movement of the traveler around the ring will in
be reduced to a minimum. Moreover since the
traveler is symmetrical with reference to its ma
jor axis or to the major axis of the cross-sec
tion thereof, a perfectly balanced construction
is provided.
15
If desired, the edges of the traveler or ends of
the oval surfaces shown at 23 and 24 may be
slightly rounded instead of sharp.
Although one speci?c embodiment of the in~
20 a traveler so designed as to cross-section as to
vention has been particularly shown and de- 20
equalize the weight, thereby producing a more
perfect balance,
Further objects of the invention will appear
from the following speci?cation taken in connec25 tion with the drawing which forms a part of this
application and in which
scribed, it will be evident that modi?cations and
changes in the construction may be made with
out departing from the spirit and scope of the
invention, as expressed in the following claims.
Having thus described my invention, what I <5,
claim is:
Fig. 1 is a sectional elevation of a traveler ring
having mounted thereon one form of traveler
1. A ring traveler having means for embrac
ing a traveler ring, said traveler cross section
constructed in accordance with the invention, and
having on opposite sides of the major axis there
31)
Fig. 2 is an enlarged transverse sectional elevation of the traveler.
In the embodiment of the invention illustrated
in the drawing there is shown a traveler Ill
which may be of any desired form or shape and
35 in the form illustrated has hooks H and [2 formed
on the ends thereof for embracing the spinning
ring 13. The yarn Y is shown as leading down-
wardly to the ring Ill, passing under the angular
portion l5 of the ring and being led to the bobbin
40 or spool S.
The particular novel feature of the traveler
of convex, symmetrical surfaces.
30
2. A ring traveler having means for embracing
a traveler ring, said traveler cross section hav
ing oppositely facing convex, symmetrical sur~
faces, said convex surfaces meeting at each len
gitudinal edge of the traveler in a line.
3;,
3. A ring traveler having means for embracing
a traveler ring, said traveler cross section having
oppositely facing convex, symmetrical surfaces,
said convex surfaces meeting at the edges of the
traveler.
4D
4. A ring traveler having means for embracing
consists in the cross-section which is shown in
a traveler ring, said traveler having a cross sec~
the enlarged view in Fig. 2. From this ?gure it
will be noted that the surfaces 25) and 21 of the
tion comprising oppositely facing symmetrical,
convex surfaces, said surfaces converging from
45 traveler are curved and meet at the edges 23
and 24 in lines which lie in the plane of the
major axis of the cross-section.
the center to the edges of the traveler.
