Abstract
Abstract A desoldering device consisting of a cylindrical container housing a coil of stranded wire impregnated with a small amount of soldering flux, the container having an elongated outlet conduit through which the stranded wire is extended to act as a wick. The stranded wire absorbs melted solder by capillary action when the wire is held against a soldered joint and heat is applied thereto.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A desoldering device comprising a holder having a dispensing aperture and a length of stranded wire carried by the holder and extending through said dispensing aperture, whereby the extended end portion of the wire may be employed as a solder wick element, wherein said stranded wire is impregnated with soldering flux, whereby to induce capillary action when the wick element is applied under heat to a solder joint, wherein said holder comprises an elongated container adapted to be employed as a handle, and wherein said holder has an elongated substantially rigid relatively small-diameter conduit portion communicating with said dispensing aperture, said stranded wire extending through and frictionally engaging in said conduit portion, whereby the extended end portion of the wire is substantially supported against flexure adjacent the end of the conduit portion.
Claim 2
Dependent Claim
132 words
A desoldering device comprising a holder having a dispensing aperture and a length of stranded wire carried by the holder and extending through said dispensing aperture, whereby the extended end portion of the wire may be employed as a solder wick element, wherein said stranded wire is impregnated with soldering flux, whereby to induce capillary action when the wick element is applied under heat to a solder joint, wherein said holder comprises an elongated container adapted to be employed as a handle, and wherein said holder has an elongated substantially rigid relatively small-diameter conduit portion communicating with said dispensing aperture, said stranded wire extending through and frictionally engaging in said conduit portion, whereby the extended end portion of the wire is substantially supported against flexure adjacent the end of the conduit portion.
Claim 3
Dependent Claim
21 words
The desoldering device of claim 1 and wherein said holder comprises an elongated container substantially axially aligned with said conduit portion.
Claim 4
Dependent Claim
15 words

Claim 6
Dependent Claim
35 words
The desoldering device of claim 2 and wherein said container has a front wall provided with a peripheral flange and said elongated conduit portion has a transverse support element lockingly engagable with said peripheral flange.
Claim 7
Dependent Claim
26 words
The desoldering device of claim 5 and wherein said transverse support element comprises a cover disk formed with a recess lockingly receiving said container front wall.
Claim 8
Dependent Claim
