Heat shielded handle for an electrically heated hand tool
| Details |

Attorney, Agent or Firm: Young & Thompson
A hand tool for heating a workpiece includes an elongated electric heating element, a heat applying member conductively connected at one end of the heating element and in alignment therewith, and an elongated cover surrounding and spaced from the heating element. The heating element and heat applying member are connected to the cover adjacent only one end of the cover, with the connection defining the sole heat conductive path therebetween. A handle is disposed at generally right angles to the cover. A relatively wide bent bracket member, including a hair-pin shaped portion, substantially coextensive in length with the cover and disposed between the cover member and handle, connects the handle to the cover solely at the opposite end of the cover. The cover dissipates heat throughout its length and the bracket is wide enough to shield the handle from the heat dissipated by the cover. Thus the cover and bracket member shield the handle from heat generated by the heating element with the tool is in operation. |

DETAILED DESCRIPTION What we claim is: 1.
A hand tool for heating a workpiece comprising an elongate electric heating element, a heat applying member conductively connected to one end of the heating element and in alignment with the longitudinal axis thereof, an elongate cover member extending in spaced relation around and generally parallel to the heating element, means for securing said heating element and said heat applying member to one end of said cover member with said heat applying member extending outwardly of said cover member, said securing means defining the sole heat conductive connection therebetween, a handle disposed generally at right angles to the cover member, a relatively wide, bent bracket member connected to said handle and connected in heat conductive contact with said cover member solely at the opposite end of said cover member, said cover member being adapted to dissipate heat along its length from said one end to said opposite end, said bracket member being arranged to form a shield between said cover member and handle, whereby said cover member and said bracket member shield said handle from heat generated by said heating means when said hand tool is in operation, said bracket member comprising spaced, parallel elongated first and second portions, each substantially coextensive with said cover member, said first and second portions having a width at least as great as the width of said cover member and being joined together at one end in a hairpin configuration, said first portion lying in lateral spaced relation beneath and parallel to said cover member and having its other end secured to said cover member at said opposite end of the cover member, said handle being secured to the other end of said second portion, said handle extending substantially at right angles to said second portion.
2.
The hand tool according to claim 1, comprising clamp mounting means for securing the handle to said second portion.
3.
The hand tool according to claim 1, wherein an electrical lead for supplying the heating element with electric power passes through holes in the first and second portions of the bracket member and in the cover member, the portion of the lead extending between the first and second portions running, over a substantial length, generally parallel thereto
