Claim 7

In a heated tool incorporating a tool life prolonging heat flow control system, the combination comprising: a. a work contacting portion adapted to be heated; b. a heat source spaced from said work contacting portion; c. means for conducting heat from said source to said work contacting portion; d. control means for regulating the rate of heat flow between said heat source and said work contacting portion; e. said control means being adjustable to cause a low rate of heat flow from the source to the work contacting portion when the tool is not in use; f. said control means also being adjustable to cause a high rate of heat flow to the work contacting portion during tool use; g. said heat source constituting an extension of the end of the tool; h. said work contacting portion lying alongside said heat source to receive a limited heat flow therefrom; i. the work contacting portion being so supported as to be movable into contact with said heat source in order to increase the rate of heat flow; j. the work contacting portion of the tool not being subjected to high temperatures except when the tool is in use so that corrosion of the work contacting portion is minimized.

Claim 8

In a heated tool incorporating a tool life prolonging heat flow control system, the combination comprising: a. a work contacting portion adapted to be heated; b. a heat source spaced from said work contacting portion; c. means for conducting heat from said source to said work contacting portion; d. control means for regulating the rate of heat flow between said heat source and said work contacting portion; e. said control means being adjustable to cause a low rate of heat flow from the source to the work contacting portion when the tool is not in use; f. said control means also being adjustable to cause a high rate of heat flow to the work contacting portion during tool use; g. said heat source being in the form of an elongate mass lying parallel to the axis of the tool; h. said work contacting portion normally lying alongside the heat source for receiving heat therefrom; i. said heat source and said work contacting portion being supported on the tool for relative movement to vary the space and therefore the heat flow therebetween; j. the work contacting portion of the tool not being subjected to high temperatures except when the tool is in use so that corrosion of the work contacting portion is minimized.
