Abstract
Abstract A solder extractor apparatus is configured as a self-contained bench unit ving a pump motor to provide an instantaneous source of pressure or vacuum available to the operator from a common port on the apparatus, the pump being started by the operator when he lifts the solder extractor iron from its support holder, and thereafter, the use of the pressure or vacuum being controlled by a foot operated switch so as to be available at the appropriate time in the solder extraction process.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
Solder extractor apparatus for use with a hollow solder extractor iron comprising: a chassis; an electric motor and pump assembly for generating a vacuum input and a pressure input; said inputs being available at a single common port on said chassis; means for selectively connecting one of said inputs through the port ot said solder extractor iron; a circuit for connecting said motor to a secure of power; a holder for supporting said solder extractor iron; a switch on said holder operable to a closed position by the absence of the solder extractor iron; said switch being electrically connected in said circuit with said motor; whereby removal of the extractor iron from its holder will close the switch and energize the motor and pump assembly making said selected input automatically available to the solder extractor iron upon the commencement of the solder extraction operation.
Claim 2
Dependent Claim
144 words
Solder extractor apparatus for use with a hollow solder extractor iron comprising: a chassis; an electric motor and pump assembly for generating a vacuum input and a pressure input; said inputs being available at a single common port on said chassis; means for selectively connecting one of said inputs through the port ot said solder extractor iron; a circuit for connecting said motor to a secure of power; a holder for supporting said solder extractor iron; a switch on said holder operable to a closed position by the absence of the solder extractor iron; said switch being electrically connected in said circuit with said motor; whereby removal of the extractor iron from its holder will close the switch and energize the motor and pump assembly making said selected input automatically available to the solder extractor iron upon the commencement of the solder extraction operation.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein a solenoid and associated valve is provided for each vacuum and pressure input, and a switch is provided alternately to select the energizing of one of the solenoids.
Claim 4
Dependent Claim
31 words
The apparatus of claim 2 wherein a foot operated switch is provided electrically positioned between the source of power and the manual switch for controlling the energization of the selected solenoid.
Claim 5
Dependent Claim
21 words
The apparatus of claim 1 wherein means are provided for varying the amount of pressure flow to the solder extractor iron.
Claim 6
Dependent Claim
59 words
The apparatus of claim 1 wherein said apparatus includes a chassis having two electrical outlets, one outlet located at each left and right side of the cabinet to enable the solder extractor iron and other tools to be postioned with respect to the sides of the cabinet depending on the left hand or right hand dexterity of the operator.
Claim 7
Dependent Claim
17 words

Claim 8
Dependent Claim
94 words
Solder extractor apparatus for use with a hollow solder extractor iron comprising: an electric motor and pump assembly for generating a vacuum input and a pressure input; means for selectively connecting one of said inputs to said solder extractor iron; means for making said selected input available upon demand including; a circuit for connecting said motor to a source of power, a solenoid and associated valve for each vacuum and pressure input, a selector switch for energizing alternately one of said solenoids, a foot operated switch for controlling the energization of the selected solenoid.
Claim 9
Dependent Claim
94 words
Solder extractor apparatus for use with a hollow solder extractor iron comprising: an electric motor and pump assembly for generating a vacuum input and a pressure input; means for selectively connecting one of said inputs to said solder extractor iron; means for making said selected input available upon demand including; a circuit for connecting said motor to a source of power, a solenoid and associated valve for each vacuum and pressure input, a selector switch for energizing alternately one of said solenoids, a foot operated switch for controlling the energization of the selected solenoid.
Claim 10
Dependent Claim
17 words
The apparatus of claim 7 wherein operation of the electric motor is controlled by a second switch.
