12 Claims.

This invention relates to a ring traveler for spinning and twisting frames; and has for one of its objects the provision of a traveler which may be more easily applied to a ring by reason of its 5 construction than travelers of the usual construction, which have heretofore been made.

Another object of the invention is the provision of a traveler which although being provided with means to allow it to be more easily placed upon the ring, will not change its weight and therefore not change its running position on the ring.

Another object of the invention is the provision of a traveler which will not load or acquire lint accumulation which changes the running qualities of the traveler on the ring.

Another object of the invention is the provision of means which act not only to permit the traveler to be more easily placed on the ring, but also has the additional property of reducing the lint accumulation or load of the ring.

A further object of the invention is the provision of a traveler so constructed that it may be made readily by machine operations and without reducing the strength of the traveler.

A still further object of the invention is the provision of a means which will reduce the breakage of the travelers when applied to the ring by causing them to be more flexible and easily applied.

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.

Ring travelers used in spinning and twisting are found to be a very important element in obtaining the quality of yarn desired, and an important element with reference to the breakage of the yarn, or as it is frequently termed in spinning language keeping the ends up, particularly at the very high rates of speed which are being used in spinning at the present time. Many of these travelers in spinning acquire a rate 15 of over a mile a minute and travelers when made of suiflcient hardness to withstand the use to which they are put are often difficult to spring over the flange of the ring by spreading the horns and sometimes in placing them in position the traveler will break; and in order to avoid these undesirable results, I have provided a traveler which is more flexible at a suitable point desired to enable it to be more readily positioned on the ring and without breakage to the traveler; and I have accomplished this without reducing the stock of the traveler, and thus I have not changed its weight or running properties by spreading out the stock to make it thinner and more flexible at one point, and I have also acquired a further and more desirable advantage which is that of preventing loading to a material extent of the traveler and one which will have less end breakage by reason of this construction than travelers heretofore made; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results are accomplished.

With reference to the drawing, ll] designates the ring having an upper flange H and lower flange l2; these flanges being interchangeable by turning the ring over.

The traveler is designated I 4 and consists of horns l5 and I6 connected by a shank or bow portion H on a generally continuous curvature, and formed over an arbor in the usual manner to acquire this curvature and shape desired. This traveler will run with substantially a single point of contact at the inner edge of the ring, such as at the point I 8, as illustrated in Figure 1, the yarn I9 being shown as passing through the traveler to be guided about the bobbin as it comes from the rolls.

The distance between the horns l 5 and I6 is of such extent as to require these horns to spread apart as the traveler is being forced over the flange of the ring. In Figure 2, the traveler I l is shown in dotted lines in its normal position as being applied to the ring and showing the relation of the distance between the horns to the flange, while in full lines, I have illustrated the traveler as sprung open to increase the distance between the horns that it may pass over the flange of the ring, and in order that this spreading of the horns may more readily take place and the pressure required to force the traveler onto the ring lessened, I have thinned the stock as at 20, at a point substantially the middle of the traveler, as illustrated, so as to preserve the balance of the traveler regardless of whether the horn I5 is on the outer or inner web of the ring.

This thinning or flattening of the stock is caused by striking the traveler and with a hammer like blow during its formation which causes the stock to be squashed down or squeezed'out and thinned, as illustrated inthe drawing, see Figures 1, 2, 3 and 7, and at the same time the stock spreads out to provide protruding portions 2| and 22 on either side of the traveler which I control to provide the proper shape of spread by the shape of the tool used to transmit the pressure required, and while I choose to form this traveler by striking it on the inner surface, as illustrated in Figures ,1, 2, 3 and 7, I may also strike the traveler on the outside to preserve the curvature on the inner surface 23 and thus flatten out the outer surface as at 25, as illustrated in Figure 4, or in addition to providing a single thinned portion, I may strike this traveler at other points such as 25 and 26 on either side of the center thinned portion in Figure 6, so as to provide a plurality of points of bending where desired, or as illustrated in Figures 8 and 9, this flattening may occur either at the points 30, Si or 32, or at all three points if desired on the vertical traveler.

The flattening or spreading of the stock in this manner maintains the same amount of stock as would be maintained in a traveler having a wire of regular or uniform size throughout its length, but spreads this stock in a different shape,

, yet I have a traveler in which every right angular cross section taken through the traveler or wire I will have the same sectional area, regardless of where the sections are taken, and by this arrangement I maintain the weight of the traveler substantially the same as it was before, so that the horizontal neutral axis and center of gravity are not disturbed and yet a traveler is provided which by reason of its shape will permit of greater resiliency orflexibility at these points where the change in shape occurs.

This shaping also has the further advantage of reducing the loading of the traveler. As the yarn l9 runs through the traveler (see Figure 1) there are at times small particles of fibers scraped oil of the yarn, and while .usually these particles are blown or fly off, at times, the twist of fibers or for some other reason they embrace the traveler lodging thereon about the traveler and do not dislodge by the air blowing across, and when so gripping the traveler the particles through centrifugal force travel from the inside where the yarn engages to the opposite outside bend of the traveler and there accumulate to form what is known as loading, and Ihave found that by spreading the stock of the traveler at a point along the traveler over which these fibers must pass that these fibers will be spread out in a wider form and be blown from the traveler and that loading is thus in many instances prevented and is materially decreased. I further find that in running a traveler of this character, there are fewer ends down, that is, there are fewer breakages, than with a traveler of the usual construction, and which I attribute partly to the prevention of loading.

In the operation of this traveler, it is frequently found that the yarn will traverse back and. forth along the traveler to a certain extent, and I find that by the provision of this broadened portion 20 of the traveler that I may control or localize this traverse and reduce the extent thereof.

I have also illustrated in Figures 10 and 11 at 40, a differently shaped traveler and have also shown thefl'attened'portion 4| as provided herein to permit of the advantageous results being obtained as above specified.

The foregoing description is directed solely .towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the appended claims.
