RING TRAVELER

Application October 4, 1937, Serial No. 167,294
5 Claims.
This invention relates to improvements in ring
travelers, and particularly of the vertical type of
travelers adapted for use in twisting machines,
and of such construction as will avoid and over
come objections to ring travelers heretofore in
general use.
The present invention relates to a traveler for
use in twisting machines and in the handling of
various kinds of yarn. Prior to the development
10 of the present traveler the usual type of vertical
traveler was made with the two ends, or horn
and foot portions, at substantially a 90° angle
with the body or shank or back of the traveler.
Such a traveler in use lies at an angle such that
the top of the traveler leads the bottom of the
traveler in revolving around the ring. Traveling
in this fashion at considerable velocity the tend
ency is for the air to pushdown on the top of
the traveler and hold down on the bottom of the
20 traveler with the net result that the entire trav
eler is forced downwardly by the air.
In the case of o?set travelers heretofore in
use the top or horn and bottom oi.’ the travelers
are bent at such an angle to the body of the trav
eler that said portions are substantially parallel
to the upper and lower edges of the ring while
the traveler is in use.
In the use of a traveler
of this nature there would be normally no air
pressure causing either a lift or a downward push
on the traveler.
The present invention relates to an improve
ment in a traveler wherein the horn or top of
the traveler is bent at an angle greater than the
angle at which the traveler lies in use, that is,
wherein the forward edge of the horn is at an
angle to the rear edge forming in effect a pocket
wherein the air is caught under such top portion
with the result that as the traveler moves around
on the ring the air pressure on the inner face
40 of the horn will tend to lift the traveler upwardly
away from the ring against the force of gravity
which normally would hold the traveler down
on the ring.
One form of my invention is shown in the ac
companying drawing wherein corresponding nu
merals of reference indicate corresponding parts
in the several views, and in which:—
Fig. 1 is a rear perspective View of my inven
tion showing its use on a vertical twister ring;
Fig. 2 is a fragmentary view of a ring with
a rear view of the traveler mounted thereon;
Fig. 3 is a section on the line 3—3 of Fig. 2;
and
Fig. 4 is a fragmentary view of the ring, in
front elevation, with a traveler mounted thereon.
(Cl. 118-61)
In the drawing, I0 designates a vertical twister
ring in the rail ll, of a twister frame, of any
usual construction, wherein the ring has recip
rocating vertical movement in the direction of
the arrows shown in Fig. 1. In this ?gure there 5
is also shown a portion l2 of the yarn or thread
which is delivered to the traveler l3 from the
usual delivery rolls and which passes from the
traveler to the spool or bobbin on which the yarn
is being wound.
10
The present traveler, as shown in perspective
in Fig. 1, comprises a foot portion I4 which en
compasses the lower edge of the ring In and is
substantially parallel thereto, the outer end of
this foot portion being bent upwardly as at I5 in 15
the usual manner.
This traveler has a shank
portion l6 which extends upwardly and inwardly
as at I‘! to a point l8 where it merges with the
horn or top portion l9 of the traveler. Said
horn or top portion l9 extends on its rear or
trailing edge from the point l8 substantially out
wardly on a line parallel with the bottom foot
portion. From the front or leading edge '20 of
the horn portion the top portion [9 extends out
wardly and upwardly at an angle to the rear edge 25
and the horn portion terminates in a portion 2|
bent sharply downward, thus forming in effect
a pocket 22 for the air; the air pressure against
the under surface of the horn, as indicated by
the arrow in Fig. 1, causing the lifting or ele- 30
vating of the traveler and raising of the same
against the force of gravity when the traveler is
revolving around the ring.
The main feature of the present traveler is the
provision of a horn portion of this character such 35
that the air is caused to contact with the under
surface of the horn portion and the traveler is
thereby always held in position on the ring with
the horn portion above and free of the ring, while
in 1186.
40
The advantages: in the use of such a traveler
will be obvious from the opening statement here
in and. it will be readily seen that in operation
the traveler is held, as shown in all of the ?gures,
with the upper end of the shank of the traveler 45 ' '
and the horn portion above and away from the
upper edge of the ring, whereby a. pocket is pro
vided such that the air is directed against the
under face of the. horn or head portion, holding
the same away from the upper edge of the ring 50 r
and obviously avoiding any tendency of the yarn
becoming soiled by reason of grease or oil from
the traveler. It will also be seen that in the use
of the present traveler considerable friction is
avoided in that in use no portion of the horn or 55
