SPINNING RING.

Application med June a,

T all whom it may concern Be it known that I, SUMNER FORBES, a

citizen of the United States, and resident of Brookline, county of Norfolk, State of Massachusetts, have invented an Improvement: in Spinning Rings, of which the following description, in connection with the accompanying' drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to spinning rings of that type which include a casing or holder which is provided with a bearing member or lining of self-lubricating material and an annular traveller operating within the casing. As exemplifying spinning rin s of this type I would refer to United States atents No. 957,759, May 10, 1910 and No. 1,333,072. March 9, 1920.

One of the objects of the present invention is to provide an improved spinning ring of this type which is constructed so that the annular, traveller will be subjected to a minimum friction when the spinning ring is started up thereby obviating any danger that the yarn will become broken and providing a structure which may be successfully used for spinning even the finest yarns.

Another object of the invention is to provide an improved spinning ring of this type which is constructed with a 'novel yarn clearer arranged so that in case the yarn does become broken the eye of the traveller will be protected from the loose end of yarn which is extended from the bobbin. Other objects of the invention-are to improve generally spinning' rings of this type all as will be more fully hereinafter set forth..

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment of. the invention which will now be described after which the novel features will be pointed out in the appended claims.

support for the annular traveller indicated at 7. The under member 1 is provided with I 1,460,751 UNITED. sTA Es PATENTOFFICE.

This base mem-' her 1 is formed with the inwardly directed the annular bead 8 and the upper member 2 of the casing has its lower end 9 shaped to snap over the bead, saidupper member 2 having the flange 10 at its upper end which overlies the 1iner3. The liner is thus retained between the flanges 10 and 5. This liner is formed with an annular travellerreceiving recess 11 in which the traveller is received and the portion 12 of the liner overhangs the traveller The traveller is provided with the usual stem 13 having an eye 14 at its upper end, said stem passing up through the opening in the liner and being supported above the stem.

' The parts thus far described are, or may be, all as usual in spinning rings of this type and form no part of my present invention. In spinning very fine yarns 1t sometlmes suflicient to cause breakage of the yarn and one of the objects of my present invention is to provide a structure for reducing such friction. I accomplish this herein by giving the outer wall 1 5 of the traveller-receiving recess a scalloped formation as shown in'Fig. 2. Asa result of this construction the traveller 7 can engage the walll5 only at the separated points 16 and hence if during the starting up of the spinning frame the traveller isdrawn to one side of the recess 11 it will bear against the wall 15 only at separatedpoints and therefore much less friction will'be developed than if the traveller had an extended bearing against the wall of the recess.

., After the spinning ring is in Operation of the'recess with the depending portion 116' which will engage the traveller when the latter is in its raised position. This.'depending portion 116 has a-less width than the traveller and will produce less friction than if the traveller bears against the upper face of the'recess throughout its entire width. Moreover the space outside of the depending portion 116 forms an air chamber in which the. air is given a whirling motion by the rotation ofthe traveller and the presence of such rotating current of air tends to keep the traveller free from lint. I

It sometimes happens that a yarn will break .during the spinning operation and when this occurs with spinning rings of this type heretofore used the loose end 17 from the bobbin 18 will fly out by centrifugal force and will constantly strike the eye 14 thusfilling up the eye-with lint so that before the end can be pieced up it is necessary for the operator to clear the eye.

In order'to avoid this I have provided a protecting finger which receives the whip of the loose end 17 a d which protects the eye 14 from said endfik i This protecting nger is indicated at. 19 and it extends upwardly from the upper side ofthe spinning ring at an inclination in the direction in which the bobbin rotates.

Said protecting finger 19 is long enough to extend slightly above the eye 14 and is situat'ed outside of the path of travel of said eyeso that it does not interfere with the rotation of the'traveller. I

If, however, the yarn breaks the loose end will strike the finger 19. at .'each rotation of the bobbin and the inclination of the finger will raise the yarn up above the level of the eye as the yarn sweeps over the finger. Upon breakage of the yarn the traveller will naturally come to rest in substantially the positions shown in Figs. 1 and 4 and when in this position the loose end 17 will be directed over the eye by the finger 19 at each rotation of the bobbin so that the eye will not be whipped by the loose end and there-.

fore will not become filled upwith lint- I claim.
