Abstract
Abstract A temperature controlled heat delivery head for heat staking electrical contact retention clips in rapid succession in an insulator. A large heat-conductive body acts to store heat and to deliver it to a substantially smaller heat-conductive projection. The body is maintained at, for example, about 820° F. The projection is maintained at, for example, about 830° F.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
243 words
Heating apparatus comprising: a delivery head including a heat conductive storage body and a heat conductive projection fixed relative to said body, said projection extending outwardly of said body to deliver heat to each successive one of a plurality of work pieces, said projection being in heat conductive relation with said body; a first thermocouple fixed contiguous to said projection and being sensitive to the temperature of said projection; a second thermocouple fixed contiguous to said body and being sensitive to the temperature of said body; a first heating element fixed relative to said projection in heat conductive relation therewith for supplying heat directly to said projection; a second heating element fixed relative to said body in heat conductive relation therewith for supplying heat directly to said body; first means connected from said first thermocouple to said first heating element to keep said projection at a first predetermined approximately constant temperature, said first temperature being the working temperature of a work piece; and second means connected from said second thermocouple to said second heating element to keep said body at a second predetermined approximately constant temperature, said body having a size and said first and second means acting in a manner such that heat is quickly resupplied to said projection after heat therein has been conducted to a work piece so that said projection quickly regains said working temperature before engaging the next one of said work pieces thus making possible increased production.
