  • Patent number: 5433005
    Abstract: A hammer and chisel device for clearing slag from welds includes a chipping chisel interchangeably and springingly affixed within a weighted handle having a slip resistant grip. Since welds often produce slag in a hard to reach spot, the invention provides for repeated one handed slag removal. A sturdy chisel with a resilient cutting surface is replaceably received by the handle utilizing a releasable retaining washer and retaining ring. A spring within the handle returns the chisel shank to an extended position, thereby providing for repeatable hammer-like blows to the chisel shank by the handle. The handle or striking rod includes a chisel shank guide receiving track for consistent sequential strikes without axial rotation. A molded slip resistant grip minimizes necessary grip pressure and prevents hand slippage. Heavy construction provides sufficient force for quick, one handed operation. A slim design provides for easy handling and use in harder to reach places.
