Abstract
An electric hand-held resist pen with an improved font and holder is disclosed. The font holder includes arcuate prongs for slidably engaging the font. By sliding the font up and down in the font holder, the heat eminating from the resistance heat to the font to its contained materials is varied and, thus, the flow rate of the material from the pen is controlled.
Claims4
Apparatus for controlling the rate of flow of molten material from the tip of an electric resist pen to a work piece comprising:
- (a) a font for containing flowable material;
- (b) a capillary tip passing through said font to its interior whereby material in said font may flow to said work piece;
- and
- (c) heat conducting font holding means including coupling means for connecting said font holder at one end to a resistance heat source and transverse font grasping means at said other end, said font grasping means slidably engaging said font whereby, by adjusting variable font resting positions, the amount and placement of heat transferred from holder to font is controlled, thereby controlling said flow rate of molten material from said pen.
