Patent Images
1. A tool kit for bending wire into shaped articles comprising:
- a. a base block having an upper and lower surface and;
b. a mandrel for bending wire consisting of a plurality of pins having an essentially cylindrical shape and;
c. a plurality of cylindrical holes for receiving said pins, wherein said holes traverse through said block between said upper and lower surfaces, each hole having a first portion and a second portion in essentially co-axial alignment and;
d. said first portion of said cylindrical holes having a diameter larger than the diameter of said cylindrical pins, and said second portion having a diameter approximately 0.032 less than the diameter of said cylindrical pins, wherein said first and second portions cooperate to form a shelf at the conjunction of said portions and;
e. said conjunction of said first and second portions of the cylindrical holes being proximal to lower block surface and;
f. wherein a plurality of said pins is inserted into said cylindrical pin receiving holes in a pattern of pins determined by the by the characteristic shape of the article.

Abstract
A wire bending jig adapted for jewelry manufacture having one or more arrays of holes for receiving bending pins. The jig has means to hold the tare end of the wire stock, freeing the hands for the work of bending wire. The bending jig may be held in one hand, mounted to a work table, or mounted in tandem on a base for complex tool construction.
