Abstract
Abstract A solder removing bit for use in melting solder by heat of the bit and for removing the solder by suction includes an elongated bit body having an inclined front surface. A suction bore extends the length of the body from a suction pipe opening at the rear end thereof and is exposed at the center of the inclined surface by a right-angled notch. A portion of the bore is left on one surface of the notch to form a slight groove which prevents blockage of the bore during use. A cross notch is provided across said surface of the right-angled notch to intersect the groove.

Total Claims: 4
Claim 1
Independent Claim
334 words
A solder removing bit for use in removing melted solder, comprising: a bit body; said bit body having a rear end; a suction pipe opening at said rear end of said bit body; said bit body having a front end opposite its said rear end; said bit body having a front end portion adjacent said front end; at said front end portion, said bit body having flat, parallel, side surfaces; said bit body having a top and an opposite bottom surface extending along said bit body and extending between said front end portion side surfaces; at said front end, said bit body comprising a generally inclined connecting surface that is inclined with respect to said top and said bottom surfaces and that extends between said side surfaces; a suction bore passing through said bit body from said suction pipe opening through said inclined surface; a notch cut into said inclined surface and spaced from said top and said bottom surfaces; said notch being defined by two mutually intersecting surfaces which meet at an intersection; the first of said intersecting surfaces extending in a first direction, which direction intersects the direction of extension of said top and said bottom surfaces; said first intersecting surface intersecting said inclined surface at the top of said notch; the second of said intersecting surfaces extending in a second direction, which direction is generally parallel to at least one of said bottom and said top surfaces; said second intersecting surface intersecting said inclined surface at the bottom of said notch; said intersection of said first and second surfaces extends across and through said suction bore to provide a solder entrance opening into said bore, such that said suction bore extends beneath said second surface; a suction bore notch formed in said second surface; said suction bore notch corresponding in cross-section and direction of extension to the portion of the cross-section of said suction bore that is below said intersection and below said second surface, whereby said suction bore remains unblocked.
Claim 2
Dependent Claim
334 words
A solder removing bit for use in removing melted solder, comprising: a bit body; said bit body having a rear end; a suction pipe opening at said rear end of said bit body; said bit body having a front end opposite its said rear end; said bit body having a front end portion adjacent said front end; at said front end portion, said bit body having flat, parallel, side surfaces; said bit body having a top and an opposite bottom surface extending along said bit body and extending between said front end portion side surfaces; at said front end, said bit body comprising a generally inclined connecting surface that is inclined with respect to said top and said bottom surfaces and that extends between said side surfaces; a suction bore passing through said bit body from said suction pipe opening through said inclined surface; a notch cut into said inclined surface and spaced from said top and said bottom surfaces; said notch being defined by two mutually intersecting surfaces which meet at an intersection; the first of said intersecting surfaces extending in a first direction, which direction intersects the direction of extension of said top and said bottom surfaces; said first intersecting surface intersecting said inclined surface at the top of said notch; the second of said intersecting surfaces extending in a second direction, which direction is generally parallel to at least one of said bottom and said top surfaces; said second intersecting surface intersecting said inclined surface at the bottom of said notch; said intersection of said first and second surfaces extends across and through said suction bore to provide a solder entrance opening into said bore, such that said suction bore extends beneath said second surface; a suction bore notch formed in said second surface; said suction bore notch corresponding in cross-section and direction of extension to the portion of the cross-section of said suction bore that is below said intersection and below said second surface, whereby said suction bore remains unblocked.
Claim 3
Dependent Claim
15 words
The solder removing bit of claim 1, wherein said first and second surfaces are perpendicular.
Claim 4
Dependent Claim
30 words
The solder removing bit of claim 1, further comprising a cross notch formed in and extending across said second surface near said intersection and intersecting through said suction bore notch.
