G. H. @H LIGAN TWISTER RING AND TRAVELER Marcas,- 1932.

Filed Aug. 12, 1951 Patented Mar. 81,v 1932 l UNITED. STATES f- GEORGE II. GILLIGAN, on PROVIDE-NOE, RHoDEIsLAND, 'n'ss'IcfNonV To U. s. TRAV- ELER COMPANY, 'or' PROVIDENCE, RHODE1 'IS.LAND, A CORPORATION OF RHODE y ISLAND A Application led August 12,'1931.r Serial' No. 556,524.

My invention relates-to twister rings and cooperating travelers, both of the` vertical,`

livery of the lubricant upon the ring face aty all possible points Of contact therewith by Y 10 the traveler; to enable the maintenance of the traveler in anupright or floating position relatively to the ring; to prevent lateral tipping of the traveler whereby gripping or .binding of the latter upon the Vring is often 15 induced; to aiford amaximum of clearance for the filament engaged by the traveler; to maintain the traveler in a uniform horizontal plane throughout its rotation around the ring; and ineXpens-iveness of construction.

20 Other objects and vadvantages Vwill be apparent to those familiar with the art and will be hereinafter adverted to.

My invention consists primarily in the means for accomplishing the above objects.
