Abstract
Abstract A refacing tool by which the spaced seating surfaces of an oxy-acetylene cutting torch nozzle can be refaced. The tool includes a main body member from which there extends a plurality of support members. The support members are affixed to the main body and are radially spaced from one another and support a guide member. The support members each have cutting means thereon for simultaneously engaging the spaced seating surfaces of the nozzle. The guide member slidably receives the nozzle therethrough. In one embodiment of the invention, a second guide member is supported by a mid-portion of the support members and telescopingly receives a marginal end portion of the nozzle therewithin. The refacing tool restores the seating surfaces of the torch nozzle and represents a considerable savings to the welding industry which heretofore was not realized.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
161 words
A refacing tool by which spaced seating surfaces of an oxygen-acetylene torch nozzle can be refaced, comprising: a main body by which said tool can be manipulated; a plurality of support members having opposed ends with one of said opposed ends being affixed to said main body and the other of said opposed ends extending therefrom and in radially spaced relation to one another; said radially spaced support members each having a cutting face formed thereon for simultaneously engaging the spaced seating surfaces of the nozzle; a guide member affixed to the free ends of said support members for telescopingly receiving a marginal length of the torch nozzle therewithin with spaced marginal lengths of said cutting face being brought into engagement with the spaced seating surfaces of the nozzle, whereupon the refacing tool can be axially rotated respective to the longitudinal axis of the nozzle to cause the cutting face to remove material from and thus reface the spaced seating surfaces.
Claim 2
Dependent Claim
161 words
A refacing tool by which spaced seating surfaces of an oxygen-acetylene torch nozzle can be refaced, comprising: a main body by which said tool can be manipulated; a plurality of support members having opposed ends with one of said opposed ends being affixed to said main body and the other of said opposed ends extending therefrom and in radially spaced relation to one another; said radially spaced support members each having a cutting face formed thereon for simultaneously engaging the spaced seating surfaces of the nozzle; a guide member affixed to the free ends of said support members for telescopingly receiving a marginal length of the torch nozzle therewithin with spaced marginal lengths of said cutting face being brought into engagement with the spaced seating surfaces of the nozzle, whereupon the refacing tool can be axially rotated respective to the longitudinal axis of the nozzle to cause the cutting face to remove material from and thus reface the spaced seating surfaces.
Claim 3
Dependent Claim
28 words
The refacing tool of claim 1 wherein said tool is limited to two diametrically opposed radially spaced support members, and said cutting face includes a cutting edge thereon.
Claim 4
Dependent Claim
61 words
The refacing tool of claim 1 wherein the cutting face on each of said spaced support members is in the form of a cutting edge which diverges outwardly away from said main body such that the included angle between said cutting edge of said support members determines the angle of conicity of the face of the reseated surface of the nozzle.
Claim 5
Dependent Claim
52 words
The tool of claim 1, and further including a second guide member supported by a medial length of each of the support members, said second guide member is in the form of a reduced diameter annular member which circumferentially extends about and telescopingly receives a marginal length of the torch nozzle therewithin.
Claim 6
Dependent Claim
88 words
The tool of claim 1 wherein there are only two diametrically opposed radially spaced support members; said tool further includes a second guide member supported by an intermediate length of the support members, said second guide member is in the form of a circumferentially extending skirt which telescopingly receives a marginal length of the torch nozzle therewithin, with the large seat of the nozzle being located between the guide members and the small seat of the nozzle being located between the small guide member and the main body.
Claim 7
Dependent Claim
104 words
The tool of claim 1 wherein each of said spaced support members are in the form of a blade, said blade includes a cutting edge which faces towards the longitudinal axial centerline of the tool, each said support member diverges outwardly away from said axial centerline such that the included angle between said cutting edges determines the angle of the face of the reseated surface of the nozzle; and further including a second guide member formed by an intermediate part of the cutting edges, said second guide member circumferentially extends about and telescopingly receives part of the small face of the torch nozzle therewithin.
Claim 8
Dependent Claim
72 words
The tool of claim 1 wherein there is provided two diametrically opposed spaced support members; each of said spaced support members is provided with a blade, said blade has a cutting edge thereof placed towards said axial centerline; said cutting edges diverge outwardly away from said main body such that the included angle between said cutting edges determines the angle of conicity of the faces of the reseated surfaces of the nozzle.
Claim 9
Dependent Claim
116 words
The tool described in claim 1, and further including a second guide member supported between said main body and the outer extremity of said support members, said second guide member is in the form of a circumferentially extending skirt which telescopingly receives the neck of the torch nozzle therewithin; there being only two diametrically opposed, radially spaced support members; wherein each of said spaced support members includes a cutting face having a cutting edge thereon which is placed towards said axial centerline, said cutting edges diverge outwardly away from said main body such that the included angle between said cutting edges determines the angle of conicity of the face of the reseated surface of the nozzle.
Claim 10
Dependent Claim
