ABSTRACT:
A tube cutter consisting of two frame portions or jaws, being pivoted to one another at their end portions, and further interconnected at their intermediate poritons by a large bolt through which the jaws will move relative to one another about their common pivot. The free end of one jaw carries anvil rollers, and the other jaw free end carries a discoid knife, the anvil roller and knife cooperating in tangentially cutting a tube extending transversely between the jaws free ends. The knife is freely caried by a jaw axle, which is itself freely releasably engaged through the jaw. A spring-loaded band within the knife containing jaw casing frictionally yet releasably locks the knife axle, and thus the knife, in position, by engaging a diametrally smaller portion of the knife axle.
