Abstract
Abstract An electrically heated tool for forming and shaping wax-like substances is provided with a replaceable tool tip formed from electrical resistance wire. The wire of the tip is made into a narrow loop with a gap between the sides of the loop. The gap is closed at each end and provides a capillary tube action for applying or removing melted wax-like material. The resistance wire is flattened to a thin cross section in the plane of the sides of the loop and is curved along the longitudinal length thereof.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
192 words
A tool for shaping wax-like substances comprising: a tool tip comprising a carving tool formed of electrical resistance wire with a pair of spaced, parallel electrical contact legs for supporting said tool tip, a handle member for supporting said tool tip, a quickly changeable tool socket having a body portion with a pair of spaced parallel electrical contact pins projecting through said body portion and extending from each side thereof, one of the pair of ends of said contact pins having openings for receiving said contact legs, a pair of conductive bores in one end of said handle for receiving said contact pins, electrical power conducting means extending through said handle to said conductive sockets, said carving tool having a projection comprising a narrow loop of resistance wire with sides of said loop having a narrow gap therebetween, which gap is open mid-way the length of said loop and is closed at each end providing a capillary tube action causing melted wax to flow away from the tip of the projection, and said resistance wire being substantially flattened to a thin cross section in the plane of the sides of said loop.
Claim 2
Dependent Claim
192 words
A tool for shaping wax-like substances comprising: a tool tip comprising a carving tool formed of electrical resistance wire with a pair of spaced, parallel electrical contact legs for supporting said tool tip, a handle member for supporting said tool tip, a quickly changeable tool socket having a body portion with a pair of spaced parallel electrical contact pins projecting through said body portion and extending from each side thereof, one of the pair of ends of said contact pins having openings for receiving said contact legs, a pair of conductive bores in one end of said handle for receiving said contact pins, electrical power conducting means extending through said handle to said conductive sockets, said carving tool having a projection comprising a narrow loop of resistance wire with sides of said loop having a narrow gap therebetween, which gap is open mid-way the length of said loop and is closed at each end providing a capillary tube action causing melted wax to flow away from the tip of the projection, and said resistance wire being substantially flattened to a thin cross section in the plane of the sides of said loop.
Claim 3
Dependent Claim
23 words
A tool as claimed in claim 1 in which: said relatively flat side of said loop is curved along the longitudinal length thereof.
