5 Claims.

This invention relates to a spinning or twisting ring and more especially to a composite ring having the wearing surface thereof, which is engaged by traveler, formed of a, non-corrosive, sleek material such as bakelite, glass, wood, fibre, bronze, celluloid and the like, and the other portion formed of any suitable material such as pressed steel.

It is a common practice in spinning rings and travelers which are used today, to make both of these members out of an integral piece of the same material which is usually steel. It is. a well known fact that these travelers rotate around the ring several thousand revolutions per minute and as a result the friction between the traveler and the ring becomes a very important factor. It is further known that the friction which is created between two metallic members is considerably greater than the friction caused by contact between a metallic member and some other material such as fibre, glass, wood and the like. Also, there is less friction, even in cases of metal to metal contact, when diiferent metals -are:used.as in the case ofa bronze flange and a steel traveler.

It is therefore, an object of this invention to provide a spinning ring having a traveler formed of one type of material and the wearing surface of the ring formed of another type of material so that the friction and heat caused by the motion of the traveler around the ring will be materially reduced, thus insuring a longer life of the traveler and the ring, and also making it possible to obtain ahigher spindle speed,

3 resulting in greater production of yarn.

posed between the traveler and the bobbin occupies substantially a radial position relative to the ring. At this time the pull on the strand between the traveler and the bobbin is more direct than it will be when the bobbin is built up to a considerable size; consequently, the friction will be greater. Added to this friction is the friction produced between the traveler and the flange. By providing a flange of a different material from that of the traveler, and thereby cutting down the friction, more yarn may be placed on the bobbin because less resistance is offered to the-traveler by the ring.

By providing a composite ring the: bobbin can be of a smaller diameter, thus allowing one to start the yarn with a greater direct pull between the bobbin and the traveler Without producing any greater friction. For the same reason, a larger ring can be used which means that a. greater amount of yarn can be, put on the bobbin without having to doff the frame.

It is a well known fact that yarn tension is obtained more by the weight of the traveler than by the friction between the traveler and the ring. By providing a ring having a. wearing surface comprised of a sleek, wear-resisting material, a heavier traveler can be used; consequently, these travelers will last much longer without replacement. 7 I

It is a further object of this invention to provide a spinning ring of the class described having the: wearing surface thereof composed of a suitable sleek, wear-resisting material, said wearing surface being removably secured to the base portion of the ring so that when this: surface becomes worn it-can be replaced by another without affecting the other portions of the ring.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:-

Figure 9 is an isometric view of the ring frame or the lower portion of the ring shown in Figures 7 and 8 omitting the wearing surface or flange;

Figure IQ is a-plan view of still another type of ring upon which the invention is adapted to be used;

Figure 11 is a front elevation of Figure 10;

Figure 12 is an isometric view of a segment of the ring shown in Figures 10 and 11;

Figure 13 is an isometric View of a segment of a ring showing a slightly modified form from that shown in Figures l0, l1 and 12;

Figure 14 is an isometric view showing still another modified form of ring embodying two concentric rings, the inner ring being made of' a wearing material and the exterior portion being made of metal.

Referring more specifically to the drawings, the numeral I denotes a suitable ring rail in which is secured a spinning ring I I, said spinning ring being composed of two portions. The lower portion is made 'of any suitable metal such as pressed steel, and the upper, interior portion is made of any suitable wear-resisting, sleek material such as bakelite, glass, wood, fibre, bronze, porcelain and the like. This upper portion or flange is held in position as at I3 by the upper portion of the crimped frame member I2.

It is a well known fact that in the type of ring shown in Figures 2 and 3, the greatest amount of wear onspinning rings take place upon the lower side of the inner flange of the ring;

consequently, the member I4 has been made of one of the above-named materials and so placed on top ofmember I2 that the inner flange thereof will be contacted by a suitable traveler I5. This traveler is usually made out of a suitable hardspring steel. As heretofore stated, by providing a traveler which is made of steel and by providing a wearing surface such as I4 made of another suitable sleek, wearing material, less friction and wear is caused by the contact of these two members. .40 By observing Figure 3 it will be noted that the lower portion of the upper flange of ring II has cavities or indentations I1 and I8 which 'are made to conform to the upturned portions or horns I9 and 20 of my improved traveler I5. By prov 45 viding a flange and traveler of this type, there is less likelihood of the traveler flying ofi of the flange due to the tension exerted upon the yarn as it is drawn from the drawing rolls thereabove'.

By observing Figures 1 and 2, it is seen that 50 there'isa greater direct pull upon strand 22 between the-traveler I and the bobbin '23 when the yarn is first started upon the bobbin than it will be when the bobbin builds up to a considerable'size'; consequently, a greater friction will be 55 present between the ring and the traveler and a greater force will be required to draw the yarn onto the bobbin. Not only will there'be a greater friction between the traveler I5 and strand '22, but also the friction between the flange and the traveler will likewise be greater.

Hence it is necessary to provide a wearing surface which contacts the traveler, said wearing surface being made of a material which will be sleek, wear-resisting and more durable than 5 steel.

The upper flange of this ring is provided with a suitable hole- 24 which prevents the loading of the traveler with cotton lint. As the traveler passes over this hole at a very rapid speed, an

' 7 air current will be created through the hole by thereof in a similar manner to that shown in Figures 1 to 3 inclusive. It will be noted in this form that the lower portion of the upper flange is straight and is adapted to receive the conventional traveler which has horizontal horns or elbows on the lower end thereof.

Figures 5 and 6 show another slightly modified form which is similar in all respects to the form shown in Figures 1 to 3 inclusive, except that the upper portion of base or ring frame I2 has a wider flange 30, which flange is crimped as at I3 and extends approximately two-thirds the entire distance across the upper surface of the ring. This is done in order to provide a metallic support for mounting a dog 3 I. Dog 3i has a resilient spring projection 32 integral therewith,which projection is secured as at 33 to the crimped flange portion 30. Normally this spring portion 32 holds the dogs 3| in the position shown in Figure 5 to close gap 34 in the outer flange of the ring. This gap is shown in an opened position in Figure 6 and provides means whereby the traveler I5 may be inserted onto the ring or removed therefrom without distorting the same. By extending this flange 30 it is possible to provide a composite ring. with a gap therein and a closure member for said gap so that the traveler may be easily inserted on the ring without scratching, marring or defacing the material from which the inner wearing flange is made.

Figures '7, 8 and 9 show another modified form of a ring which comprises base member or ring frame 38 which is preferably made of pressed steel. The upper periphery of member 38 has spaced opposed projections 39 and 4!] integral therewith which flare outwardly from the center line of the ring frame. adapted to fit into a suitable dove-tailed groove 4| which is cut in the-lower surface of flange 42. It will be noted by referring to Figures '7 and 8 that the groove 4| has suitable spaced pins 43 extending from the lower central portion thereof which are adapted to project downwardly between the projections 39 and 40 to normally force these flanges into contact with the opposed sides 7 of the groove. Since there is a certain amount of natural resiliency in the flared projections 39 and 48 itis quite evident that this upper flange may be removed after it hasoncebecome worn and a new flange placed thereon. On this flange a conventional traveler 45 is adapted to be placed.

Figures 10, 11 and 12 show another type of ring showing the same principle applied thereto. This ring is. broadly designated by reference character 41- and is adapted to have a traveler 48 mounted thereon. This ring has a wearing surface'or traveler track 50 which is made of any of the above-named materials, which fits on the interior of an outer shell or ring frame 5I, said frame being crimped as at 53 and 54 to the upper and lower edges respectively of the wearing surface or traveler track 50'.

Figure 13 shows a form similar to the form shown in Figure 12, except that the crimped portions 53 and 54 are not present in this form; instead. the outer shell or ring frame 55 stops short of the upper and lower edges of the ring, and the wearing surface or the traveler track extends over the upper and lower edges of the ring. This form is particularly adaptable to cases where the traveler is likely to lag upon the ring thus wearing-the upper and lower portions thereof.

Figure 14 shows still another modified form of These projections are the same may be reversed or turned over when one flange becomes worn. In this form the inner portion or wearing surface thereof is composed of a ring 58 made of any suitable material such as glass, bakelite, bronze, celluloid, porcelain and the like, and having an outer ring 59 preferably made of steel. Upon these flanges a suitable traveler 60 is adapted to be placed. Likewise, in the outer flange of the ring 59, a hole 6|, is provided for preventing the traveler from becoming loaded with cotton lint and the like, and is essentially the same as the hole 24 which is shown in Figures 1 to 3 inclusive, and described therein in detail.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. A spinning or twisting ring having a flanged portion for the reception of a traveler, said flanged portion having a hole therethrough whereby currents of air will be induced through said hole by the motion of the traveler to remove lint from the traveler and ring.

2. A textile ring comprising a base formed from sheet metal and having inner and outer spaced sidewalls joined at the bottom of the base and open at the top, and a wearing member for receiving a traveler secured to the upper edges of said base.

3. A textile ring comprising a base formed from sheet metal having inner and outer sidewalls and crimped to form a ledge on the exterior thereof for supporting the ring in a ring rail, a wearing member for reception of a traveler, and interengaging means between the lower surface of the wearing member and the upper edges of the inner and outer sidewalls of the base for securing the wearing member and the base together.

4. A textile ring comprising a base formed from sheet metal and having inner and outer sidewalls, and having a continuous projection on the exterior of the outer sidewall. the upper edge of the inner and outer sidewalls being spaced from each other and flared outwardly, a wearing member for the reception of a traveler, said wearing member having a groove in the lower surface thereof adapted to receive the upper edges of the inner and outer sidewalls for confining the wearing member on the base.

5. A textile ring comprising an outer portion formed from sheet metal and having a projection on its outer periphery for supporting the ring in a suitable ring rail, a wearing portion disposed on the inside surface of said sheet metal portion, said wearing portion having a corresponding irregular outer surface fitting against the inner surface of the sheet metal portion to confine the wearing portion in said sheet metal portion.
