TIRE TOOL. Application ?led my ‘14, 1921. Serial No. 484,564.

To all whom it may concern: , manent ring or ?ange 11 of the rim 12. A Be it known that I, FRANK R. HARTSOCK, holding ?nger 13 is secured to the lower a citizen of the United States'of America, surface of the arm 5 and engages beneath and resident of Warsaw, Kosciusko County, the ?ange of the rim, as clearly shown in 55 5 Indiana, have invented a certain new and Fig. 2, so that vthe arm 5 ?rmly grips the useful Improvement in Tire Tools, of which rim ?ange.
