Abstract
Abstract A cup-shaped thermomagnetic temperature sensing element is secured to the soldering tip of a heat controlled electric soldering iron by electroplating the shank end of the tip which fits into the cup-shaped thermomagnetic element with a thin coat of iron. The electrodeposited iron coating produces an enlargement at the edges of the reduced diameter shank forming a tapering surface axially inwardly. The cup-shaped thermomagnetic element may then be positioned over the enlargement and mechanically deformed around said enlargement to securely hold the thermomagnetic element to the end of the soldering tip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A soldering tip assembly for use in a thermomagnetic element, heat controlled electric soldering iron comprising: a soldering tip having both a working end and a shank end, and a thermomagnetic cup-shaped material positioned at the shank end, said shank end being provided with an edge remote from said working end and surrounding said shank end, an electrodeposited iron coating covering said soldering tip, said coating being of greater thickness in the area contiguous to said edge, said coating forming an enlargement at said edge, said thermomagnetic cup-shaped material having an internal bore receiving said shank end and said enlargement, said thermomagnetic cup-shaped material being deformed around said enlargement and fixedly secured to said shank whereby said thermomagnetic material is held firmly in place on the shank end of said soldering tip.
Claim 2
Dependent Claim
132 words
A soldering tip assembly for use in a thermomagnetic element, heat controlled electric soldering iron comprising: a soldering tip having both a working end and a shank end, and a thermomagnetic cup-shaped material positioned at the shank end, said shank end being provided with an edge remote from said working end and surrounding said shank end, an electrodeposited iron coating covering said soldering tip, said coating being of greater thickness in the area contiguous to said edge, said coating forming an enlargement at said edge, said thermomagnetic cup-shaped material having an internal bore receiving said shank end and said enlargement, said thermomagnetic cup-shaped material being deformed around said enlargement and fixedly secured to said shank whereby said thermomagnetic material is held firmly in place on the shank end of said soldering tip.
Claim 3
Dependent Claim
26 words
The soldering tip assembly of claim 1 wherein said coating forms a tapering surface along said shank end inwardly from said edge toward said working end.
Claim 4
Dependent Claim
43 words
The soldering tip assembly of claim 1 wherein said soldering tip is provided with a reduced diameter shank end protruding axially from a larger diameter shank portion of said soldering tip and wherein said reduced diameter shank end is provided with said enlargement.
Claim 5
Dependent Claim
32 words
The soldering tip assembly of claim 1 wherein said enlargement is between 5 and 200 per cent greater than the thickness of the coating along the smooth surface of the soldering tip.
Claim 6
Dependent Claim
29 words
The soldering tip assembly of claim 1 wherein the outside diameter of the soldering tip assembly is substantially the same across the thermomagnetic cup-shaped material and the soldering tip.
Claim 7
Independent Claim
107 words
The method of securing a thermomagnetic cup-shaped material to the shank end of a soldering tip to form a soldering tip assembly for use in a thermomagnetic element heat controlled electric soldering iron comprising: forming a reduced diameter shank end at one end of the soldering tip remote from the working end, forming an edge substantially surrounding said shank end, electrodepositing a coating of iron on the soldering tip, forming an enlargement from said coating contiguous to said edge, inserting said cup-shaped thermomagnetic material onto said shank end and deforming said cup-shaped thermomagnetic material around said enlargement to fixedly secure said thermomagnetic material to said shank end.
Claim 8
Independent Claim
107 words
The method of securing a thermomagnetic cup-shaped material to the shank end of a soldering tip to form a soldering tip assembly for use in a thermomagnetic element heat controlled electric soldering iron comprising: forming a reduced diameter shank end at one end of the soldering tip remote from the working end, forming an edge substantially surrounding said shank end, electrodepositing a coating of iron on the soldering tip, forming an enlargement from said coating contiguous to said edge, inserting said cup-shaped thermomagnetic material onto said shank end and deforming said cup-shaped thermomagnetic material around said enlargement to fixedly secure said thermomagnetic material to said shank end.
Claim 9
Dependent Claim
34 words
The method of claim 6 wherein said electrodeposited iron forming the enlargement is of a thickness of 5 to 200 per cent greater than the coating deposited upon a smooth surface of said tip.
Claim 10
Dependent Claim
21 words
The method of claim 7 including forming said enlargement onto an inwardly tapering surface from said edge toward said working end.
