Abstract

Abstract A soldering iron and tip therefor in which the tip has a bore along its longitudinal axis with a transverse vent opening through the tip connecting with the bore to increase the capillary action of drawing solder up into the bore. An arrangement is also provided for threading a braided wire into the bore to further enhance the capillary action. In the latter case it is preferred that a second hole be formed in the tip at an angle to the bore.

Claim 6
Dependent Claim 30 words
A tip as in claim 1 wherein said bore extends only part way of the length of the tip from the active end thereof at least until said vent passage.
Claim 7
Dependent Claim 29 words
A tip as in claim 1 wherein the active end is forked with at least a pair of tines, the bore opening in the tip located between said tines.
Claim 8
Dependent Claim 38 words

Claim 9
Dependent Claim 185 words
A tip for a soldering iron in which the tip is an elongated generally cylindrical member of heat conductive material, said tip having an active end for placement adjacent an area where solder is to be melted and another end adapted for connection to a solder iron for heating the tip, a single bore only of substantially uniform diameter throughout formed axially in said tip extending along at least a portion of the length thereof and having an opening at the active end of the tip, said tip also formed with a vent passage and a second passage which extend from the outer surface of the tip at points spaced from the active end through at least a part of said tip to communicate with said bore with said second passage being more remote from the active end of the tip than said first passage, and a piece of wire braid material extending through one of said passages, said bore and out of the opening of said bore at the active end of the tip to provide a plurality of capillary passages for molten solder.
Claim 10
Dependent Claim 185 words
A tip for a soldering iron in which the tip is an elongated generally cylindrical member of heat conductive material, said tip having an active end for placement adjacent an area where solder is to be melted and another end adapted for connection to a solder iron for heating the tip, a single bore only of substantially uniform diameter throughout formed axially in said tip extending along at least a portion of the length thereof and having an opening at the active end of the tip, said tip also formed with a vent passage and a second passage which extend from the outer surface of the tip at points spaced from the active end through at least a part of said tip to communicate with said bore with said second passage being more remote from the active end of the tip than said first passage, and a piece of wire braid material extending through one of said passages, said bore and out of the opening of said bore at the active end of the tip to provide a plurality of capillary passages for molten solder.
Claim 11
Dependent Claim 26 words
