Abstract
Abstract A method and apparatus for transposing a pair of railroad rails. In the embodiment of the invention described below, a selfpropelled rail-transposing machine having a pair of rail threader eyes at both the front and rear of the machine is provided, with the two rails being threaded through these four eyes so that they cross beneath the machine. Hydraulic cylinders are preferably included for moving the eyes vertically and horizontally and for individually tilting the threader eyes to twist the rails so that, on double-shoulder tie plates, the rails will come over the shoulder when spikes are pulled only on one side of the rail. Further, a hydraulic clamp and thrust jack is provided on the machine for moving up to a quarter mile or so of a rail along its length in either direction to realign transposed rails having staggered joints.

Claim 1
Independent Claim
200 words
Apparatus for transposing a pair of railroad rails of the type having staggered joints comprising: means for moving each of said rails along its length in a direction and for a distance so that each rail can be attached to the joint formerly attached to the outer rail including clamping means adapted to be clamped to a rail, said clamping means including a clamping member having a passage for a rail and a wedge member having an eye for connecting said wedge member to hydraulic jack means and adapteD to be fitted in said passage between said clamping member and said rail and hydraulic jack means connected to said clamping means for exerting a force on that rail to move it along its length, and means for transposing said pair of rails including a vehicle having a frame and means to move said frame along said rails and wherein said moving means includes means attaching said hydraulic jack means to said frame, said attaching means attaching said hydraulic jack means pivotably to said frame so that said jack means is free to pivot about an axis substantially perpendicular to the direction of the force exerted by said hydraulic jack means.
Claim 2
Dependent Claim
200 words
Apparatus for transposing a pair of railroad rails of the type having staggered joints comprising: means for moving each of said rails along its length in a direction and for a distance so that each rail can be attached to the joint formerly attached to the outer rail including clamping means adapted to be clamped to a rail, said clamping means including a clamping member having a passage for a rail and a wedge member having an eye for connecting said wedge member to hydraulic jack means and adapteD to be fitted in said passage between said clamping member and said rail and hydraulic jack means connected to said clamping means for exerting a force on that rail to move it along its length, and means for transposing said pair of rails including a vehicle having a frame and means to move said frame along said rails and wherein said moving means includes means attaching said hydraulic jack means to said frame, said attaching means attaching said hydraulic jack means pivotably to said frame so that said jack means is free to pivot about an axis substantially perpendicular to the direction of the force exerted by said hydraulic jack means.
Claim 3
Dependent Claim
199 words
Apparatus for transposing a pair of railroad rails of the type having staggered joints comprising: means for moving each of said rails along its length in a direction and for a distance so that each rail can be attached to the joint formerly attached to the other rail including clamping means adapted to be clamped to a rail, said clamping means including a clamping member having a passage for a rail and an eye for connecting said clamping member to hydraulic jack means and a wedge member adapted to be filled in said passage between said clamping member and said rail and hydraulic jack means connected to said clamping means for exerting a force on that rail to move it along its length, and means for transposing said pair of rails including a vehicle having a frame and means to move said frame along said rails and wherein said moving means includes means attaching said hydraulic jack means to said frame, said attaching means attaching said hydraulic jack means pivotably to said frame so that said jack means is free to pivot about an axis substantially perpendicular to the direction of the force exerted by said hydraulic jack means.
Claim 4
Dependent Claim
199 words
Apparatus for transposing a pair of railroad rails of the type having staggered joints comprising: means for moving each of said rails along its length in a direction and for a distance so that each rail can be attached to the joint formerly attached to the other rail including clamping means adapted to be clamped to a rail, said clamping means including a clamping member having a passage for a rail and an eye for connecting said clamping member to hydraulic jack means and a wedge member adapted to be filled in said passage between said clamping member and said rail and hydraulic jack means connected to said clamping means for exerting a force on that rail to move it along its length, and means for transposing said pair of rails including a vehicle having a frame and means to move said frame along said rails and wherein said moving means includes means attaching said hydraulic jack means to said frame, said attaching means attaching said hydraulic jack means pivotably to said frame so that said jack means is free to pivot about an axis substantially perpendicular to the direction of the force exerted by said hydraulic jack means.
Claim 5
Dependent Claim
186 words
Apparatus for transposing a pair of railroad rails comprising: frame means, means for moving said frame means along said pair of rails, four guide member means attached to said frame means with two of said guide members on one end of said frame means and two of said guide members on the other end of said frame means, each of said guide members defining a passage for a rail, arm member means for each guide member connecting that arm member means to said frame, first hydraulic jack means associated with each said arm member means for moving that arm member means vertically, second hydraulic jack means associated with each said arm member means for moving that arm member means horizontally, third hydraulic jack means associated with each said guide member means for rotating that guide member means, and hence a rail in said passage, clamping means adapted to be clamped to a rail, and fourth hydraulic jack means connected to said clamping means and to said frame means for exerting a force on the clamped rail so as to move the clamped rail along its length.
