Abstract
Abstract An electrically heated soldering element with a removable cartridge of solder received within a cavity in the element with a spherical valve mounted in the tip of the element and communicating with a solder-dispensing tubular extension on the cartridge so that inward movement of the valve sphere will open the valve to allow dispensing of melted solder from the cartridge.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
A soldering means having a heating element with a heated tip portion comprising, a solder cartridge-receiving chamber in said heating elemEnt for receiving a cartridge container of solder, a cartridge container of solder in said chamber, a solderdispensing tubular extension extending from said cartridge, a solder discharge conduit in said tip portion communicating with said solder-dispensing tubular extension for gravitationally dispensing solder from said tip when solder within said cartridge is melted with said discharge conduit including valve means comprising a spring-urged valve closure member movable to an open position for allowing discharge of melted solder and movable to a closed position for preventing discharge of melted solder wherein said spring-urged valve closure member is mounted in a removable valve body cup threadedly received within said tip and is biased outwardly from said tip and has a projecting portion projecting outwardly of said tip so that engagement of said projecting portion with an object to be soldered will move said closure member inwardly for opening said valve to allow melted solder to flow therefrom onto the object to be soldered.
Claim 2
Dependent Claim
180 words
A soldering means having a heating element with a heated tip portion comprising, a solder cartridge-receiving chamber in said heating elemEnt for receiving a cartridge container of solder, a cartridge container of solder in said chamber, a solderdispensing tubular extension extending from said cartridge, a solder discharge conduit in said tip portion communicating with said solder-dispensing tubular extension for gravitationally dispensing solder from said tip when solder within said cartridge is melted with said discharge conduit including valve means comprising a spring-urged valve closure member movable to an open position for allowing discharge of melted solder and movable to a closed position for preventing discharge of melted solder wherein said spring-urged valve closure member is mounted in a removable valve body cup threadedly received within said tip and is biased outwardly from said tip and has a projecting portion projecting outwardly of said tip so that engagement of said projecting portion with an object to be soldered will move said closure member inwardly for opening said valve to allow melted solder to flow therefrom onto the object to be soldered.
Claim 3
Dependent Claim
20 words
The invention of claim 1 wherein said spring-urged closure member is a spherical ball mounted within said valve body cup.
Claim 4
Dependent Claim
23 words
The invention of claim 2 additionally including a vent extending through said tip and communicating with the interior of said valve body cup.
Claim 5
Dependent Claim
45 words
The invention of claim 3 wherein said tip portion includes a solder-dispensing face from which melted solder is dispensed from said valve body cup and a planar working face adjacent said dispensing face and oriented at an acute angle with respect to said dispensing face.
Claim 6
Dependent Claim
22 words
The invention of claim 4 wherein said spherical ball includes a portion which extends outwardly from the surface of said solder-dispensing face.
Claim 7
Dependent Claim
45 words
The invention of claim 5 wherein said solder-dispensing face is oriented at an angle with respect to the longitudinal axis of said heating element at an acute angle less than the angle at which said working face is oriented with respect to said heating element.
Claim 8
Dependent Claim
40 words
The invention of claim 1 wherein said tip portion includes a solder-dispensing face on which melted solder is dispensed and a planar working face adjacent said dispensing face and oriented at an acute angle with respect to said dispensing face.
Claim 9
Dependent Claim
20 words
The invention of claim 7 wherein said spring-urged closure member is a spherical ball mounted within said valve body cup.
Claim 10
Dependent Claim
23 words
The invention of claim 8 additionally including a vent extending through said tip and communicating with the interior of said valve body cup.
Claim 11
Dependent Claim
36 words
The invention of claim 9 wherein said spherical ball includes a portion which extends outwardly from the surface of said solder-dispensing face when said solder-dispensing face is not in engagement with a surface to be soldered.
