Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
109 words
A mobile system for correcting the position of a track, which system advances along the track in a working direction and comprises a track correction assembly arranged at a track correction station to move the track to a corrected position, and a reference controlling the track correction, the reference including track surveying means in contact with the track for indicating the actual track position and the corrected track position assumed upon movement of the track by the track correction assembly at a track surveying station rearwardly of the track correction station, in said working direction, the distance between the track correction assembly and the track surveying means being variable.
Claim 2
Dependent Claim
109 words
A mobile system for correcting the position of a track, which system advances along the track in a working direction and comprises a track correction assembly arranged at a track correction station to move the track to a corrected position, and a reference controlling the track correction, the reference including track surveying means in contact with the track for indicating the actual track position and the corrected track position assumed upon movement of the track by the track correction assembly at a track surveying station rearwardly of the track correction station, in said working direction, the distance between the track correction assembly and the track surveying means being variable.
Claim 3
Dependent Claim
23 words
In the mobile system of claim 1, the track correction assembly consisting of means for laterally shifting the track for lining the track.
Claim 4
Dependent Claim
22 words
In the mobile system of claim 1, the track correction assembly being mounted for movement in respect of the track surveying means.
Claim 5
Dependent Claim
22 words
In the mobile system of claim 1, the track surveying means being mounted for movement in respect of the track correction assembly.
Claim 6
Dependent Claim
63 words
In the mobile system of claim 4, a mobile frame carrying the track correction assembly and the track surveying means, the reference including a reference line operatively associated with said means, a forward and a rear station to which respective ends of the reference line are anchored, and means for holding the forward and rear stations at adjustable distances from the mobile frame.
Claim 7
Dependent Claim
52 words
In the mobile system of claim 5, a plurality of means for anchoring the respective rEference line ends to each of the forward and rear stations, said means being spaced on each station in the direction of track elongation and being selectively usable to anchor the reference line ends to said stations.
Claim 8
Dependent Claim
31 words
In the mobile system of claim 1, the variable distance between the track correction assembly and the track surveying means being adjustable during the advance of the system along the track.
Claim 9
Dependent Claim
51 words
In the mobile system of claim 1, the track correction assembly and the track surveying means being so mounted for movement in respect of each other that the track correction assembly may selectively assume the forward position in respect of the track surveying means in opposite working directions of the system.
Claim 10
Dependent Claim
25 words
In the mobile system of claim 1, a mobile frame carrying the track surveying means in the range of the center point of the frame.
Claim 11
Dependent Claim
34 words
In the mobile system of claim 1, a mobile frame carrying the correction assembly, the assembly being mounted on a carrier mounted for movement on the frame in the direction of the track elongation.
Claim 12
Dependent Claim
69 words
In the mobile system of claim 10, the track correction assembly including track gripping means and said means being pivotally mounted on the carrier to enable the same to be pivoted into positions permitting the assembly carrier to be moved past the track surveying means so that the assembly may selectively assume the forward position in respect of the track surveying means in opposite working directions of the system.
Claim 13
Dependent Claim
43 words
In the mobile system of claim 1, the track correction assembly including rail gripping means glidingly or rollingly engaging the rail or rails to permit continuous advance of the system while the rail or rails are engaged for correction of the track position.
Claim 14
Dependent Claim
14 words
In the mobile system of claim 1, means for vibrating the track correction assembly.
Claim 15
Dependent Claim
26 words
In the mobile system of claim 13, wherein said vibrating means is mounted in association with, and for vibrating, drive means for the track correction assembly.
Claim 16
Dependent Claim
54 words
In the mobile system of claim 14, wherein the track correction assembly includes two rail gripping means arranged for engaging a respective one of the track rails, two motors for laterally moving a respective one of the rail gripping means, and said vibrating means being mounted centrally of said motors for vibrating the same.
Claim 17
Dependent Claim
66 words
In the mobile system of claim 13, wherein the track correction assembly includes two rail gripping means arranged for engaging a respective one of the track rails, each rail gripping means including a pair of rail gripping rollers mounted on respective axles, each of said axles having a laterally projecting extension, and said vibrating means being mounted on each axle extension for individually vibrating said rollers.
Claim 18
Dependent Claim
63 words
In the mobile system of claim 1, the reference including a forward and a rear station, and the track surveying station intermediate thereof, a bogie at each station, a reference line, means on each of said bogies for anchoring the reference line thereto, and means on at least one of said bogies for moving the anchoring means in the direction of the track.
Claim 19
Dependent Claim
34 words
In the mobile system of claim 1, the track correction assembly being mounted for movement in respect of the track surveying means, and manually controlled means being provided for moving the track correction assembly.
Claim 20
Dependent Claim
32 words
In the mobile system of claim 1, the track correction assembly being mounted for movement in respect of the track surveying means, and automatically controlled means for moving the track correction assembly.
Claim 21
Dependent Claim
21 words
In the mobile system of claim 19, the automatically controlled means being responsive to the indicated error in the track position.
Claim 22
Dependent Claim
23 words
In the mobile system of claim 19, the automatically controlled means being responsive to the extent of the spring back of the track.
Claim 23
Dependent Claim
18 words
