Abstract
Abstract A transportable machine for the but-welding of rails under field conditions. The machine is provided with a stationary pincer clamp for fixing a first rail to be welded, a movable pincer clamp for fixing another rail to be welded to the first rail, a common axle on which the pincer clamps are mounted, a drive for displacing the movable pincer clamp, a hydraulic cylinder for turning the clamping jaws of the stationary pincer clamp, a hydraulic cylinder for turning the clamping jaws of the movable pincer clamp, at least two profile cutters rigidly secured to the clamping jaws of the movable pincer clamp and having a form contoured to the head and side portions of the rail in cross section, at least one lower cutter mounted on one of the pincer clamps and adapted to reciprocate transversely in relation to the longitudinal axis of the rail, the lower cutter having a cutting edge which coincides with the plane of the rail foot.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
162 words
A rail butt-welding Transportable machine disposed on a rail under field conditions, comprising in combination a stationary pincer clamp for fixing a first rail to be welded, a movable pincer clamp for fixing another rail to be welded to the first rail, a common axle on which said pincer clamps are mounted, a drive for displacing the movable pincer clamp, a hydraulic cylinder for turning the clamping jaws of the stationary pincer clamp, a hydraulic cylinder for turning the clamping jaws of the movable pincer clamp, at least two profile cutters rigidly secured to the clamping jaws of said movable pincer clamp and having a form contoured to the head and side portions of the rail in the cross section, at least one lower cutter mounted on one of said pincer clamps and adapted to reciprocate transversely in relation to the longitudinal axis of the rail, said lower cutter having a cutting edge which coincides with the plane of the rail foot.
Claim 2
Dependent Claim
162 words
A rail butt-welding Transportable machine disposed on a rail under field conditions, comprising in combination a stationary pincer clamp for fixing a first rail to be welded, a movable pincer clamp for fixing another rail to be welded to the first rail, a common axle on which said pincer clamps are mounted, a drive for displacing the movable pincer clamp, a hydraulic cylinder for turning the clamping jaws of the stationary pincer clamp, a hydraulic cylinder for turning the clamping jaws of the movable pincer clamp, at least two profile cutters rigidly secured to the clamping jaws of said movable pincer clamp and having a form contoured to the head and side portions of the rail in the cross section, at least one lower cutter mounted on one of said pincer clamps and adapted to reciprocate transversely in relation to the longitudinal axis of the rail, said lower cutter having a cutting edge which coincides with the plane of the rail foot.
Claim 3
Dependent Claim
56 words
A machine according to claim 1, including a further hydraulic cylinder to provide the reciprocating motion for the lower cutter in the transverse direction in relation to the longitudinal axis of the rail, said further hydraulic cylinder being secured to one of the pincer clamps, the rod of said hydraulic cylinder being connected to said cutter.
Claim 4
Dependent Claim
60 words
A machine according to claim 1, wherein said further hydraulic cylinder is mounted on one of the clamping jaws of the stationary pincer clamp, the cutting edge of the lower cutter being positioned so that the cutting of the weld burr from the rail foot is made in the transverse direction in relation to the longitudinal axis of the rail.
Claim 5
Dependent Claim
67 words
A machine according to claim 1, wherein at least one clamping jaw of the movable pincer clamp is equipped with an additional hydraulic cylinder, said additional hydraulic cylinder having a rod connected to the lower cutter, the cutting edge of said lower cutter being positioned so that the cutting of the weld burr during the travel of the movable pincer clamp is made longitudinally along the rail.
Claim 6
Dependent Claim
25 words
A machine, according to claim 4, wherein the lower cutter is arranged in guides secured on the movable pincer clamp with at least one bracket.
Claim 7
Dependent Claim
63 words
A machine according to claim 2, wherein said further hydraulic cylinder for displacing the lower cutter is mounted on one of the clamping jaws of the stationary pincer clamp, the cutting edge of the lower cutter being positioned so that the cutting of the weld burr from the rail foot is made in an orthogonal direction to the longitudinal axis of the rail.
Claim 8
Dependent Claim
67 words
A machine according to claim 2, wherein at least one clamping jaw of the movable pincer clamp is equipped with an additional hydraulic cylinder, said additional hydraulic cylinder having a rod connected to the lower cutter, the cutting edge of said lower cutter being positioned so that the cutting of the weld burr during the travel of the movable pincer clamp is made longitudinally along the rail.
Claim 9
Dependent Claim
25 words
A machine according to claim 7, wherein the lower cutter is arranged in guides secured on the movable pincer clamp with at least one bracket.
