  • Material fed I into the barrel is advanced by a motor-driven conveying screw toward an orifice at the outlet of the feed pas- [56] References cued sage.
  • the barrel is secured to a pistol-gripand housing UNITED STATES PATENTS portion of the device in such manner as to enable inter- 3,337,093 8/1967 Newton 222/l46 HE changeability of barrels, and to minimize heat transfer Davis 219/302 X from the barrel to the grip and housing.
  • This invention relates generally to extruding apparams, and more particularly relates to hand-held apparatus adapted for extruding materials displaying thermoplastic properties.
  • polymeric sealant materials are thermoplastic rubber-based compositions which have come into increasing use for sealant applications, as for example where it is desired to effect a seal between the glass windshield and mating frame of an automobile.
  • Such compositions may, for example, comprise polymerized butyl-based compounds; or may be based on polysulfide polymers, on styrene-butadiene rubber polymers, on acrylonitrile-butadiene rubber polymers, on other butyl rubbers, on neoprene, urethanes, or on combinations of these several components, and/or of other synthetic rubber-based materials.
  • the basic objective sought to be achieved by the artisan is to lay down a bead of the sealant in a prescribed pattern upon one 1 of the surfaces'to be joined.
  • the said material is commercially furnished in rope-like form,and in order to provide the desired well-defined bead, apparatus have from time to time been proposed which in one manner or another, extrude the sealant material under operator control.
  • the sealant material is thermoplastic in nature, a superior bead is deposited if the material-is first heated so that the extrudate may wet the surface upon which it is deposited and otherwise adhere firmly thereto. For such reason it has also been proposed in certain of the aforementioned prior apparatus, that heating be provided during the process ofextrusion.
  • thermoplastic sealant materials which is readily held and actuated by an operator, and which is provided with means enabling accurate and uniform heat control of the extrudate.
  • thermoplastic sealant materials which includes efficient variable speed means for feeding the said materials, which provides for uniform and highly regulated heating of the extrudate, and which moreover minimizes heating and electrical hazards to an operator.
  • thermoplastic sealant materials which provides readily interchangeable barrel portions, whereby an operator may readily change the apparatus configuration for extru sion of successive types of differing materials, thereby avoiding contamination.
  • a hand-held apparatus including a barrel having a material feed passage extending therethrough and a plurality of heating element passageways extending parallel to the feed passage.
