ABSTRACT:
A simple and economical tire repair tool, providing an open-ended support tube which carries in the free end a plug member axially of the tube for sealing the hole. The plug member is provided on its forward end with a hard-material pointed member for penetration of the casing, and that pointed member has an abutment against which the free end of the support tube presses during use, forcing the pointed end and a plug body connected thereto to penetrate the tire casing, without need of enlarging the hole, and with the tube holding the casing walls away from the plug body. Interengaging lugs of the tube and the pointed end member provide for twisting the pointed member to facilitate passage of the pointed member into the casing, but permit simple axial retraction of the tube to draw it out of the casing, yet the resilience of the casing in the hole region causes the casing walls to firmly embrace the plug member, sealing the hole.
