Abstract
A chain pipe-cutter is made up of chain links joined together by cross bars, the cross bars further engage cutting wheels. A pair of adapters each having a U-shaped body with a pair of longitudinally oriented legs joined together by a back portion from which the legs depend. The legs have holes so the adapters may engaged with one of the chain links at a terminal position on the chain by cross bars. The back portions providing a groove having a longitudinal orientation so that with the chain wrapped around a brittle pipe the adapters are positioned in near adjacency, and may be further forced into convergence by a tool engaging each of the longitudinal grooves to sever the pipe.
Claims5
A workpiece-cutting apparatus for being compressively drawn by a clamping tool around a workpiece, the apparatus comprising:
- a flexible, non-extensible metal chain having a plurality or cutting wheels aligned longitudinally along the metal chain and rotationally engaged therewith;
- opposing ends of the metal chain each terminating with an adapter;
- each said adapter providing a pair of legs supporting therebetween at least one of the cutting wheels;
- each said adapter further having a clamping groove longitudinally extensive and directed along the adapter without extending through the adapter;
- the apparatus circularly configurable for encircling a workpiece with each said pair of legs directed toward the workpiece and with each said clamping groove directed away from the workpiece;
- wherein one of the adapters further provides a guide groove and another of the adapters provides a guide tongue;
- the guide groove and the guide tongue engagable when the apparatus is circularly configured, whereby, when the adapters are drawn together, contact forces of the cutting wheels sever the workpiece.
A workpiece-cutting tool apparatus positioned around a workpiece for being compressively drawn by a clamping tool, the apparatus comprising:
- a flexible, non-extensible metal chain having a plurality of cutting wheels aligned longitudinally along the metal chain and rotationally engaged therewith;
- opposing ends of the metal chain each terminating with an adapter;
- each said adapter providing a pair of legs supporting therebetween at least one of the cutting wheels;
- each said adapter further providing a clamping groove;
- the apparatus encircling the workpiece with each said pair of legs directed toward the workpiece and with the cutting wheels in contact with the workpiece;
- and each said clamping groove longitudinally extensive and directed along the adapter without extending through the adapter and directed away from the workpiece;
- whereby, when the adapter are drawn together, contact forces of the cutting wheels sever the workpiece.
A workpiece-cutting apparatus for being compressively drawn by a clamping tool around a workpiece, the apparatus comprising:
- a flexible, non-extensible metal chain having a plurality of cutting wheels aligned longitudinally along the metal chain and rotationally engaged therewith;
- opposing ends of the metal chain each terminating with an adapter;
- each said adapter providing an elongate clamping groove longitudinally extensive and directed along the adapter;
- the apparatus circularly configurable for encircling a workpiece with each said clamping groove directed away from the workpiece.
