Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A heating device for a heat activated binder system comprising in combination: a. parallel spaced side walls connected to a bottom wall defining a U-shaped slot for holding an article to be heated and bound, b. an electrical heating element positioned on the bottom wall of said slot and switch means activated in one direction by heat expension from said heating element whereby said switch means shuts off current to said heating element after a desired amount of heat has been developed, c. said switch means including a two position snap action switch having an "off" position and an "on" position with manual means for moving said switch from the "off" position to the "on" position and means activated by heat expansion to snap said switch to the "off" position when a desired temperature has been reached whereby said switch remains in "off" position until it is again manually actuated to the "on" position.
Claim 2
Dependent Claim
