Abstract
Abstract Apparatus for the vertical and lateral movement of a section of railway track. Gripping members are operated to grip the two lines of rails. The gripping members are mounted on at least one support frame connected by articulated connecting members to the chassis of a track maintenance vehicle movable on the track. The support frame is movable both vertically and laterally relative to the vehicle under the action of lifting members or lining members, to move said track section and to bring it into a predetermined reference position. The apparatus comprises in combination vertical and lateral support members connected to the support frame to guide the same and supported on at least one line of rails and guidance and control members for moving each gripping member relative to the support frame in directing both vertical and transverse to the track.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
Apparatus for the vertical and lateral movement of a section of railway track wherein gripping members operated so as to be able to grip the two lines of rails are mounted on at least one support frame connected by articulated connecting members to a chassis movable on the track, which support frame is movable both vertically and laterally relative to said chassis under the action of lifting members or lining members, in order to move said track section and to bring it into a predetermined reference position characterized in that said gripping members are provided for each side of the track and are displaceable, substantially in a straight line, transversely in relation to the support frame; and in that rail engaging means, for each side of the track, are mounted on the support frame and are operable to engage the track so as to face the gripping members for the same side of the track.
Claim 2
Dependent Claim
155 words
Apparatus for the vertical and lateral movement of a section of railway track wherein gripping members operated so as to be able to grip the two lines of rails are mounted on at least one support frame connected by articulated connecting members to a chassis movable on the track, which support frame is movable both vertically and laterally relative to said chassis under the action of lifting members or lining members, in order to move said track section and to bring it into a predetermined reference position characterized in that said gripping members are provided for each side of the track and are displaceable, substantially in a straight line, transversely in relation to the support frame; and in that rail engaging means, for each side of the track, are mounted on the support frame and are operable to engage the track so as to face the gripping members for the same side of the track.
Claim 3
Dependent Claim
24 words
Apparatus as claimed in claim 1 in which said gripping members are also vertically displaceable in a straight line relative to said support frame.
Claim 4
Dependent Claim
45 words
Apparatus according to claim 1, characterised in that each gripping member of a line of rails is height-adjustably mounted on an intermediate chassis which is itself displacably mounted on said support frame in a plane parallel to the plane of the track and transversely thereto.
Claim 5
Dependent Claim
42 words
Apparatus according to claim 3, characterised in that the control of the vertical displacement of a gripping member relative to its intermediate chassis is obtained by a device comprising multiple spacer blocks interchangeable as desired by means of a pre-selection control member.
Claim 6
Dependent Claim
37 words
Apparatus according to claim 1, characterised in that the support frame extends at least over the entire width of the railway track and supports the gripping and supporting members of two lines of rails of said track.
Claim 7
Dependent Claim
49 words
Apparatus according to claim 5, characterised in that the articulated connecting members connecting the support frame to the chassis of the vehicle comprise control members for moving said support frame longitudinally to the track or rotating the same in a plane substantially parallel to the plane of said track.
Claim 8
Dependent Claim
40 words
Apparatus according to claim 6, characterised in that the articulated connecting members connecting the support frame to the chassis of the vehicle comprise at least one guidance member for preventing said support frame turning on itself about its longitudinal axis.
Claim 9
Dependent Claim
71 words
Apparatus according to claim 5, characterised in that the vertical and lateral support members of the support frame are mounted on at least one axle parallel to said support frame, said axle being displaceable along its axis by means of at least one control member which is extensibly connected to the support frame so as to be supported against the side of the head of one or other line of rails.
Claim 10
Dependent Claim
46 words
Apparatus according to claim 8, characterised in that the control means for displacing the axle of the vertical and lateral support members of the support frame produce a force which is at least equal to half that of the lining members which move said support frame.
Claim 11
Dependent Claim
34 words
Apparatus according to claim 8, characterised in that the axle upon which are mounted the vertical and lateral support members of the support frame is height-adjustably mounted on and relative to said support frame.
Claim 12
Dependent Claim
171 words
