US 5,509,799 A · Flint replaceable lighter

Abstract

The invention is a flint replaceable lighter. In a preferred embodiment the invented lighter includes a lighter body including means for containing fuel. Fitted upon it is a striker wheel assembly including a striker wheel, a striker wheel support superstructure into which the striker wheel is inserted and a hollow support shaft disposed below said superstructure. A flint is loosely disposed in the support shaft, with the upper end of a spring inserted in the support shaft below the flint. The spring urges the flint against the striker wheel above it. When the user removes the spring, the spent flint may be removed and a new one inserted into the shaft. The spring is then reinserted into the shaft as well. The lighter body is outfitted with a means for releasably receiving the striker wheel assembly. In a preferred embodiment orientation means are disposed on the striker wheel assembly and the receiving means for assuring that said striker wheel assembly is received by said receiving means in a correct orientation. When the striker wheel assembly is inserted into the receiving means, it is then swivelled into its operational position.
