RING AND TRAVELER FOR SPINNING AND TWISTING FRAMES Filed April 18, 1935 Rdph R azz Patented June 2, 1936 mom TRAVELER roa SPINNING AND TWISTING FRAMES Ralph Bagan, Atlanta, Ga., assignor to Steel Heddle Manufacturing Company, Philadelphia, -'Pa., a corporation of Pennsylvania Application April 18, 1935, Serial No. 16,95 17 Claims. (o1. 118-59) This invention relates to rings and travelers for spinning and twisting frames, and in some respects comprises certain improvements in the invention described and claimed in my previous 5 application for Letters Patent, Serial No. 731,248. The principal obiect of the present invention is to provide a ring and traveler for spinning and twisting frames, which will operatemore efliciently and uniformly than the rings and travolcrs at present in common use.

A further object of the invention is to provide a'ring and traveler'to be used inconnection therewith, which are so constructed and arranged as to insure a large bearing surface at the place where the traveler contacts with the ring in its movement about the same.

A further object of the invention is to provide improved means for lubricating the bearing surface of the ring, whereby a sufflcient, but not'excesslve quantity of lubricant will at all times be present on said bearing surface.

A further object of the invention is to provide a ring and traveler construction in the use of which there is taken into account the resultant of the forces imposed by the tension of the yarn as well as the centrifugal action of the mass of the traveler, to the end that amore uniform twist in the yarn will be obtained, and irregularities in and breakage of the yarn will be greatly reduced.

A further object of the invention is to provide Figure 1 is a top plan view of'a ring and traveler employed in connection therewith, embodying the main-features of the present invention;

a Fig. 2 is an enlarged sectional view thereof,

taken approximately on the line 2-2 of Fig. 1; Fig. 3 is an elevational view of the traveler shown in Fig. 2, this view being taken in the direction of the arrow 3 on Fig. 2, the traveler shown being that provided where the yarn is to have a right hand twist imparted thereto, and the 5 device is to be used in connection with a spindle rotating in a contra-clockwise direction, as indicated by the arrow shown in connection with Fig. 3;

Fig. 4 is a horizontalsection of the bearing porton of the traveler shown in Fig. 3, this section 6 being taken on the line 4-4 of Fig. 3, the yarn engaging portion of the traveler being shown removed therefrom;-

Fig. 5 is a view similar to Fig. ing a form of traveler to be used where the yarn is to have a left hand twist imparted thereto, and the spindle rotates in a clockwise direction,- as indicated by the arrow shown in connection with Fig. 5;

Fig. 6 is a similar view of a modified form of traveler, which may be used under certain conditions in which the hole in which the yarn engaging ortion in mounted is symmetrically disposed inthe bearing portion of the traveler, the yarn engaging portion being 'in this instance .swung in either direction, whereby the same may be used for imparting either a right or a left hand twist to the yarn; and

Fig. '7 is a similar view of another modifled' form of traveler, in which the'bearing portion is provided with a pair of holes, in either of which the yarn engaging portion of the traveler may be mounted, depending upon whether file traveler is used to impart a right or a left hand twist to the yarn.

, It will, of course, be understood that the description and drawing herein contained are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departingfrom the spirit of the invention.

Referring to the drawing,- III is a ring made of any preferred material, such, for example, as any of the alloy steels commonly used for such purpose. This ring may be hardened and pol- 40 ished in the usual manner. The ring III has a base portion l I of sufiicint area in cross-section to afford the necessary rigidity.

A portion I2 extends upwardly from the base 3, but illustratportion I l of the ring, being so shaped as to pro- 45 vide an inner bearing surface I3, which is made frusto-conical for a purpose to be presently ex-; plained. The small diameter. of the frusto-conical bearing surface (3 is disposed upwardly.

At the upper end bf the upwardly extending portion l2 there is provided an inwardly extending flange I 4, which serves to limit the upward displacement of the traveler. to be hereinafter ,described. At the lower part of thefring Hi there is providedan inwardly extending flange I5,

which serves to limit the downward displacement of said traveler, and also assists in feeding a lubricating medium to the bearing surface l3 of the ring in an eflective mannen,

An oil reservoir l6, preferably made of pressed sheet metal, is mounted on the ring it by means of an upwardly extending rim II, which frictionally engages the outer surface of the base portion ll of the ring. The oil reservoir I6 is so shaped as to provide an annular chamber It, disposed below the base portion ll of the ring.

.In this chamber I! there is mounted an annular oil covered surfaces of the ring it against the accumulation of the fly and grit which are thrown centrifugally outward during the spinning and twisting operation. This guard wall 2| of the oil reservoir also serves to prevent broken ends of the yarn from coming in contact with the oil covered surfaces of the ring andbecoming fouled thereby. Furthermore, the guard wall 2! serves to prevent the base of the bobbin from contacting with the traveler, as sometimes happens with the ordinary types of rings and travelers.

The traveler comprises two members, a yam engaging-portion 22, made of a length of wire or a metallic strip,-suitabiy bent to provide a curved portion 23 around which the yarn passes in the usual manner; and a bearing portion 24, comprising a small metallic block having one surface complemental in shape to the frustoconical bearing surface It of the ring.

The yarn engaging portion 22 of the traveler is preferably madeof round wire having its ends bent inwardly toward each other, and the hearing block'portion 24 of the traveler is provided with oneor more holes 26, in which the intumed end 21 of said yarn engaging portion of the traveler is positioned. The other inturned end 28 of the yarn enga ing portion 22 of the traveler serves to prevent the traveler from, becoming detached from the ring by reason of the outwardly extending flange "provided at the top of the ring, over which the end 2' of the yarn portion 22 of the traveler may be snapped in the usual manner when it is desired to mount or demount the traveler with respect to the ring.

The hole 24 in the bearing block'portion 24 of the traveler preferably extends entirely'through said bearing block. However, the inturned end 21 of the yarn engaging portion of the traveler is preferably shorter than the thickness of the block, in this manner providing a pocket in which a portion of the lubricating medium may be trapped, thereby to be more evenly distributed over the bearing surface It: of the ring. The hole; 28 in the" bearing block portion 24 of the traveler must be properly located for the most eiilcient operation of the. traveler, the determination of the location being made by taking into consideration the distribution of the mass of the bearing block portion 24 and of the yarn enga i D0rtion'22 of the traveler, as well as the normal operating speed of. he p n l n the tension of the yarn.

Ifdesired, the end 2! oftheyarn engaging portion 22 of the travelermay be mounted in the bearing block portion 24 of the traveler with a forced fit, the yarn engaging portion being set atthe proper angle with respect to the bearing block portion to insure the most eflicient opera- -5 tion. However, it may be found preferable to permit the yarn engaging portion 22 of the traveler to have a certain pivotal motion with respect to the bearing block portion 24 thereof, so that in the operation of the device the yarn engaging portion may automatically adjust itself to the proper angular position when changes occur in the speed of rotation of the spindle and in the tension of the yarn.

Ordinarily, the best location for the hole 26 in the bearing block portion 24 of the traveler, which is used for the mounting of the yarn engaging portion 22, will be slightly above the horizontal center and to the left of the vertical center of said bearing block portion, as shown in 20 Fig. 3, when the traveler is to be used for imparting a right hand twist to the yarn; and to the right of the vertical center, as shownin Fig. 5, when the traveler is to be used for imparting a left hand twist to the yarn.

In some instances it will be found permissible to locate the hole 26 0a the vertical center of the bearing block portion 24, as shown in Fig. 6, the angular position assumedby the yarn engaging portion 22 serving to obtain the proper reaction whereby the bearing surface 25 of the bearing block portion 24 of the traveler will be kept in the proper complemental relationship with respect to the frusto-conical bearing surface I! of the ring III.

In still other instances it may be found desirable to provide two holes 26 in' the bearing block portion 24 of the traveler, as shown in Fig. 7, whereby the yarn engaging portion 22 may be alternatively positioned in said holes, accordingly 40 as the traveler is to be used for imparting a right or a lefthand twist to the yarn.

A ring and traveler constructed as aforesaid will operate in a manner peculiar to itself, and differently from any of the various types of rings and travelers heretofore used or suggested. By eason of the provision of the frusto-conical surface II of the ring at the proper angle, the centrifugal action will tend to cause the traveler to descend, the force thus imparted being in addias: to the gravitational force. As opposed to the tension of the yarn passing around the yarn engaging portion 22 of the traveler will tend to raise the traveler. The desideratum is to obtain a balance between the forces thus imposed on the traveler.

It has been found, however, thateven where the traveler is provided with'a bearing block portion, if the mass thereof be disposed centrally with respect to the yarn engaging portion of the traveler, there will be a tendency on the part 0. the traveler to cook to an angular position, this by-reason of the yarn extending tangentially from the bobbin to the traveler.

In the present instance this tendency is overcome by the oif-centerposition of the hole 28, in which the yarn engaging P rtion 22 of the traveler is mounted, as well as the angular position at which the said yarn engaging portion is fixed, or which it assumes when the same is piv- 1'0 'otally mounted with respect to the bearing block portion 24 of the traveler. In this manner there is provided a distribution of the mass of the .traveler which serves to correct the tendency of the traveler. to cock and bind on the ring.

The provision of the improved means for lubrieating the bearing surface I3 of the, ring 7 III is I also an important feature of the present invention. In this instance the oil contained within the annular chamber l8 of the reservoir l6 willbe carried upwardly by the capillary action of the wick l9 until it encounters the lower surface of the inwardly extending flange l5 of the ring. The oil will then creep over the inner surface of said flange l5, and pass to the bearing surface of the ring in such' quantity as to lubricate said bearing surface sufficiently, yet not to an excessive extent.

A ring and traveler constructed as aforesaid will be found to operate more evenly and uniformly than the rings and travelers at present in common use, and burning of the ends of the traveler, by reason of their frictional engagement with the flanges of the ring, will ,be eliminated.

'In fact, the entire structure will be found to operate in a much more satisfactory manner than the present types of rings and travelers, and will per- -mit operation at higher speeds.
