ABSTRACT:
A repair apparatus for tire punctures is operable upon a damaged tubeless tire in situ and includes a hollow probe initially containing a rubber boot disposed in a collapsed condition but subsequently automatically unfolding when urged into the tire interior by a plunger rod in the probe. A stem integral with a circular main body of the rubber boot is connected to the plunger rod by a flexible tether that serves to retain the unfolded boot juxtaposed the puncture point inside the tire while a drive rod forces a measured amount of rubber bonding fluid through the probe to sealingly secure the boot. Alignment and retention of the probe and drive rod is facilitated by a mounting unit secured to the tire by adjustable attachment elements clampingly engaging the rim of the wheel mounting the tire while threads on the probe and drive rod cooperate with tapped bores in the mounting unit to permit controlled advancement and retraction of the probe and drive rod.
