ABSTRACT:
A hand manipulated electrically heated stylus tool for transferring insignia to an article from a ribbon or sheet having a coating on one face thereof subject to release and transfer to an article to be printed which operates on a 115 volt power supply without use of a voltage reducing transformer or temperature control means. The tool includes an aluminum mandrel with a surrounding sleeve of heat shrinkable Teflon on which a heating element of high resistance insulated wire is wound so that the sleeve provides back-up insulation between the wire and mandrel. The mandrel is provided with a bore which receives the tip portion of a conventional ball point pen, thus forming a heated stylus. The heated stylus assembly is disposed within a hollow frusto-conical support and is secured therein by a hardenable mixture forming heat insulation between the assembly and the support. As compared with a slidable stylus tip, the device operates smoother and with less pressure thus facilitating holding the ribbon in place on an article. The molded frusto-conical mandrel support and the potting cement therein also provides improved heat insulation resulting in a hotter stylus tip and cooler handle.
