Abstract
Abstract A fairing tool for aligning plates preparatory to welding comprising a main body proportioned to span a predetermined distance between plates and having a passageway therethrough, handle means having a portion slidably disposed in the passageway and a head at the front end thereof which is narrower than the predetermined distance but when rotated 90.degree. will span that predetermined distance. A nut engages threads on the handle means for drawing the head toward the main body and thereby forces the plate edges into planar alignment. The main body is threaded and carries a large nut which can be used to extract the tool if needed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A fairing tool for aligning plates which tool comprises main body means proportioned to span a predetermined distance between plates and including an externally threaded sleeve having a passageway therethrough and an internally threaded outer nut element, first means having a portion slibably disposed in said passageway and extending therethrough and having a head at the front end thereof which is dimensioned in one direction less than said predetermined distance so as to fit through an opening between the plates and which is dimensioned in another direction greater than said predetermined distance, said first means having handle means at the rear end thereof for rotating said head after its insertion through an opening between the plates so that it bridges such plates, and second means in contact with said first means and said main body means for moving said first means relative to said main body means whereby said head can be drawn toward said main body means to force the plate edges into planar alignment.
Claim 2
Dependent Claim
166 words
A fairing tool for aligning plates which tool comprises main body means proportioned to span a predetermined distance between plates and including an externally threaded sleeve having a passageway therethrough and an internally threaded outer nut element, first means having a portion slibably disposed in said passageway and extending therethrough and having a head at the front end thereof which is dimensioned in one direction less than said predetermined distance so as to fit through an opening between the plates and which is dimensioned in another direction greater than said predetermined distance, said first means having handle means at the rear end thereof for rotating said head after its insertion through an opening between the plates so that it bridges such plates, and second means in contact with said first means and said main body means for moving said first means relative to said main body means whereby said head can be drawn toward said main body means to force the plate edges into planar alignment.
Claim 3
Dependent Claim
37 words
A tool in accordance with claim 1 wherein said first means include an externally threaded portion and said second means comprises a nut having mating internal threads which abuts the rear end of said main body means.
Claim 4
Dependent Claim
28 words
A tool in accordance with claim 1 wherein the front end of said sleeve carries guide means extending therefrom having a width slightly less than said predetermined distance.
Claim 5
Dependent Claim
25 words
A tool in accordance with claim 2 wherein said passageway is circular and of a diameter larger than said threaded portion of said first means.
