Patented Dec. 25, 1934 UNITED STATES RING TRAVELER Edwin R. Jerome, Cranston, R. L, assignor to Victor Ring Traveler Company, a corporation of Rhode Island Application May 18, 1933, Serial No. 671,677

Claims.

This invention relates to a ring traveler of the type used in ring twisting or spinning, which operates about a horizontal flange of the ring;

and has for one of its objects to reduce the friction of the traveler on the ring thus reducing wear on both the traveler and the ring.

Another object of the invention is to produce a traveler which may be used longer upon the ring without changing travelers.

Another object of the invention is to produce a traveler which will cause an even tension on the yarn without strain and thus produce an evener yarn and one of improved quality.

Another object of the invention is to provide a traveler having relatively short horns which will permit of easy assembly of the traveler on the ring and yet will maintain the traveler against coming off during running.

A further object of the invention is to balance the traveler and the tension of the yarn extending thru the traveler so that the traveler will substantially float about the flange of the ring.

A still further object of the invention is to so lower the weight of the traveler that it will run without tipping and thus in substantially a vertical plane whereby to prevent jamming of the traveler as sometimes occurs from such tipping action.

With these and other objects in view the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a perspective view of a ring traveler.

Fig. 2 is a perspective view of a ring in section with the traveler mounted thereon in the position which it will assume in operation.

Fig. 3 is a top plan view of a portion of the ring showing the position of the traveler with reference to the ring.

Fig. 4 is a section on substantially line 44 of Fig. 3, thru the ring and the traveler to illustrate 'the plane in which the traveler moves.

Fig. 5 is a side elevation of the traveler showing the axes thereof.

Fig. 6 is a sectional view of the ring and traveler showing the traveler in its relative position thereto.

Fig. '7 is an edge view of a traveler of semicircular type showing the axis thereof.

Fig. 8 is a sectional view of the ring showing the relative running position of the traveler 'shown in Fig. '7.

Travelers for some time have been made upon substantially the arc of a circle with inwardlyextending horns at a point just below the center of the arc of the shank of the traveler and providing a substantially semi-circular shank connecting these horns. In use, there are two primary forces acting upon a traveler; one is a centrifugal force which tends to direct the traveler outwardly radially of the ring and the other force is the tension of the yarn which tends to lift the traveler vertically upwardly off the ring and which lifting is limited by the horns.

In the operation of this semi-circular traveler above mentioned the horn on the inner edge of the ring will limit the lifting movement but at this time the horizontal neutral axis of the traveler is so high above the ring that the traveler tends to fall outwardly on the ring and will do so until this neutral axis will pass thru the point of contact which the traveler has with the ring. It so happens, however, in all of this semi-circular type of traveler that the semi-circular shank is so long that the horn on the outer side of the ring will contact the outer surface of the ring before the neutral axis passes thru the point of contact which the traveler has with the inner edge of the ring, and further this high center of gravity and additional contacting point will cause the ring to tilt from a vertical plane and in some instances-jam and cause a breaking down of the end of the yarn. Also, it causes friction, heat and less length of time that the traveler may be used, and. in order to eliminate to some extent these undesirable effects I have produced a traveler which matured into Patent No. 1,846,732, dated February 23, 1932, in which I formed an elliptical shank and thus lowered to some extent the center of gravity so that the horizontal neutral axis will pass thru the point of engagement of the traveler and the ring prior to the outer horn of the traveler contacting with the outer surface of the ring, and in order to further lower the center of gravity and this axis that the ring may run with its horizontal neutralaxis more nearly level, I have lowered the weight of the traveler, and consequently the horizontal neutral axis, by lowering the horns and flattening the shank of the traveler and by reason of the reduced curvature of the ends, prevent this traveler from lifting to such an extent that it will tilt and thus it will run more nearly vertical than heretofore, which is desirable in efiecting a better action of the traveler about its ring; and the following is a more detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplished:
