TRAVELER RING AND TRAVELER FOR SPINNING on 'rw rsf'rna nannies.

Application filed November 19,4921. Serial No. 516,457.

This invention relates to traveler rings and travelers and particularly to stationarily mounted rings and travelers therefor for spinning and twister frames.

In order that the principle of the invention may be readily understood, I have represented a single embodiment thereof in, the accompanying drawing, wherein,-

Fig. 1 is a side elevation of a ring and the support therefor;

Fig. 2 is a vertical central section of the construction shown in Fig. 1 upon the line 2-2 of said figure; and

Fig. 3 is a side elevation similar to Fig. 1 but representing the ring as detached from its support or holder.

An important object of my invention is to provide a ring having certain properties including that of self-lubrication, the ring being preferably also non-corrosive and non-oxidizable and of superhardness and capable of sustaining the spinning or twlsting operation for a maximum length of time without wear. In the preferred and disclosed embodiment of the invention the ring is reversible in actual practice and even after a long period of use and particularly because of the fact that the ringis noncorrosive and non-oxidizable. These and other important features of the invention will be more fully disclosed.

Referring more particularly to the drawing, the ring holder or support is indicated at 1, it being of any suitable material and construction not herein necessary more fully to disclose. Preferably said holder or support is formed as a split ring or body as indicated at 2, so that it may frictionally engage and hold from rotation the ring indicated generally at 3. If desired d as shown a clearer 4 of any suitable construction may be employed, it being here shown as a wire coiled to lie in the groove 5 in the top face of the support or holder 1 with an upwardly extending inclined end as illustrated. The said holder or support is provided with an upstanding flange providing a shoulder 6 for the reception at its inner side of the ring 3.

The ring 3 may be of any suitable form but desirably it is reversible; To that end it is provided as herein represented with flanges 7 and 8 at opposite ends thereof, either flange being capable of being received and held by the support or holder 1. If desired, any suitable cooperating means maybe provided to retain the ring fixedly within t e suppo rt or holder, as, for example, retain ng clips or other suitable parts or devices. The invention is not limited to a ring held from rotation but the disclosed and preferable embodiment of the inven- 't1on 1s a ring which is fixed during the operation.

The ring is provided with a suitable traveler 9 which maybe of any suitable shape and is received over the upper flange. Within the scope and purpose of my invention the traveler may be of any suitable and usual material such as steel or it may be of some material such as that herein disclosed with respect to the ring 3, as will be more fully set forth.

Rings as now generally made are cut from a tube of steel and are thereafter ground. and 1n some cases rings have been spun, or forged or stamped from sheet metal and subsequently welded. Such rings are of very uncertain length of life, lasting in some cases about six months and in other cases as much as five years or more.

It has heretofore been proposed to make a ring reversible and in fact a usual construction of ring is one having top and bottom flanges for the purpose of permitting reversal thereof. As a matter of fact, however, an acceptable and successfully reversible ring has never been produced so far as I am aware because if one end of the ring be used for the traveler for a few months till "or even longer, as, for example, the flange 7, and it then is desired'to reverse the ring and use the flange 8 for the traveler, it is found that the flange 8 has oxidized or become corroded to such an extent as to render it no longer practicable to' reverse the ring and use the said flange 8 for the traveler. Hence, a ring that is really and in fact reversible has not been heretofore, produced so far as I am aware.

Owing to the high speed at which a traveler rotates about the ring, such speed averaging between 1500 and 12000 revolutions per minute, it is of the highestimportance that the ring be of a material that is hard and will withstand wear. Heretofore so far as I am aware, however,;no materialhas been found to be satisfactory, in that after a greater or less length of'time the ring wears to such an extent that it must be discarded.

It has not been feasible heretofore to lubricate a traveler ring or the traveler in general Ill ' with the alloy aluove outlined.

' able method I cast in the rough a rlng outof operation thereof because oiland grease must obviously be kept away from the commercial yarn that is being spun.

After a great deal of experimentation I have produced a, ring that is not only noncorrosive and non-oxidizable, thereby permitting it to be actually reversed, but ts high degree of hardness combined with its self-lubricating properties permits 1t to be used for a greater lengthof time than has heretofore beenpossible.

My invention comprehends a rm composed of a metal or a metalic alloy W 1011 n and of itself is a lubricant, and which is desirably non-corrosive and non-oxidizable, but preferably and to secure the results herein specified,the ring is composed at least 1n part of chromium and desirably is composed of chromium and cobalt or nickel and pref erably in the proportions of somewhat more than ten per cent, and somewhat less than about fifty per cent. of chromium, at least a part of the remainder of the alloy being c0- balt, or it may be'nickel. Other metallic 1ngredients may be included but for the purposes of the present disclosure the ring may be regarded as made at least mainly of chromium, and cobalt or nickel.

I may construct the ring of my invention in any suitable way, and I make reference to three methods of manufacture, two of which methods will result in a solid ring of the alloy above'outlined; the third method produces a rin jof steel coated or surfaced In-my preferthe suitable alloy, then grind the ring 'both on the inside and the outside .and on both flanges, lastly, I polish the ring until it presents an absolutely smooth surface; In my second method, I roll into shape a ring of the desired form after which it is necessary only to polish the ring. The rolling into shape is done hot, and it is possible to work the above outlined alloy when to the elements already mentioned is added a slight quantity of iron,-not more than twenty per cent.

The third method consists in making an under size ring of steel by any well known method, placing this ring on a rapidly rotating spindle and spraying thereupon the alloy outlined by means of an electric arc of oxy-hydrogen, or oxy-acetylene element which fuses any desired metal or material,

- combined with an air stream preferably of about-three atmospheres pressure whichatomizes the fused material and projects it upon any desired surface. Such spraying machine may be anddesirably is, of the type invented by one M. U. Schoop, of Zurich.

Switzerland, and disclosed in United States Patent No. 1,133,507 dated March 30, 1915. Such a ring is extremely hard and may be defined as superhard. It is capable of re-..

ceivin and sustaining a very high polish. It-is lnherently self-lubricating and therefore for the first time in the art, so far as I am aware, there is thus produced a ring that is in substance self-lubricating and rendered so without the employment of any material treated with an oil or other lubricant. By this I do not mean that the substance of the allo Y yields an oil or grease but that the ingre ients of the allo so co-act upon or with the traveler as to lubricate the rubbing surfaces of these parts and lessen their friction upon each other.

Because of the fact that the ring is of is therefore desirable to provide a traveler for some material that will last longer than heretofore and be of more certain life. Therefore, desirably I make the traveler of substantially the same metal or alloy as the ring, namely, of chromium with cobalt or nickel. In doing so I provide for the first time in the art a metallic traveler which is itself self-lubricating and which does not corrode or oxidize. Such traveler may be made in any suitable way..

It 15 not essential to my invention that the entire traveler ring be made of a material having ,the qualities or certain of the qualities mentioned, although this is preferable.

Within the scope of my invention one or' both of the flanges 7 and 8 or the upstanding portion 10 of the ring may be of such material. It is not, of course, essential that the ring 3 be absolutely fixed in operation as it may or can turn more or less and even though not desirable, within the broad scope and purpose of my invention it may be of the so-called rotary type of ring.

I have set forth that the ring of my invention is non-corrosive or non-oxidizable. I have also set forth that it is of great hardness. These two qualities combine to produce a highly eflicient rin It is well known that certain materia such as aluminum, are non-corrosive, but they would be wholly unsuitable for use as a spinning orftwister ringbecause they are relatively so t.

It has heretofore been proposed to provide aring with a lining or wood treated with some lubricating material'to reduce friction. Such material, however, wears very rapidly and obviously does not possess many of the properties of the material preferably embut so far as construct a rin of ceramic materials, including earthenare and porcelain, and also to construct it of glass. These materials have in practice been found to be unsuited for the purpose, being relatively fra ile and breaking easily and short lived. oreover in the case of glazed material, it' has been found that after a comparatively short time the glazed surface wears away and the underneath material is wholly unusuable as a spinning or twister ring surface.

Moreover, excepting where some such material as wood is, treated with a lubricant, there is no feature or characteristic of lubrication involved.

In those cases where a material such as wood is employed, and is saturated .or treated with a lubricating material, it is obvious'that not only is the lubricant-receiving material soft, but it is of an open, porous nature that is essentially different from the nature of the material employed by me.

I am aware that heretofore rings of metal have been actually lubricated with oil or other lubricating material, conducted thereto by capillarity or otherwise. Such provision, however, is seriously objectionable because it brings the oil or other lubricant into actual contact with the fibres that are being spun, to the great detriment thereof.

It has also been proposed to construct a ring traveler of some non-metallic material, such as horn, hard india rubber or rawhide, I am aware, such a traveler has never been used to any substantial extent, since it is obvious that such a traveler must be of short durability or life.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptlve sense and not for purposes of limitation, ing set forth Olaims-- 1. A metallic traveler, ring for textile purposes formed of an alloy of inherent superhardness and having inherent nonthe scope of the invention bein the following claims.
