Abstract
There is disclosed in the specification a tire repair device and kit for inserting plugging material typically in the form of rubber coated twisted strands into a tire puncture. The device and kit is provided with one or more interchangeable tools such as a strand inserting needle, an awl, a knife, and screwdriver, said tools being interchangeably joinable with the handle of said device. In operation the awl is first joined with said handle and used to enlarge the puncture, if necessary. The inserting needle tool is then joined to the handle. The plug material is threaded into the open eye of the needle and inserted into the puncture. The inserting motion is limited by a stop bushing captive on said needle tool so that the ends of the strands are not drawn into the puncture. The stop also limits the withdrawal of the needle. After the strand has been inserted in accordance with the present invention the knife tool may then be attached to said handle and used to trim off any excess strand of material extending out of the puncture.
