~ ccording to the present invention there is provided an apparatus for the vertical and lateral move~nent of a section of railway track wherein gripping members operated so as to be able to grip the ~wo lines Oe rails are mounted on at least one Erame connected by articulated connecting members including track lifting and lining jacks to a chassis movable on the track, which support frame is movable both vertically and laterally relative to said chassis under the action of said jacks, said gripping members being provided for each side of the traok and being displaceable along said support frame, substantially in a straight line, transversely in relation to the chassis;
and a rail engaging means for each side of the track, being mounted on the support frame so as to co-operate with the gripping member for the same side of the track.
~ccording to one preferrcd embodiment of the inYentiOn there is ~ provided an apparatus for the vertical and lateral movement of a sec~ion of railway track wherein gripping members operated so as to be able to grip from the outside the two lines of rails are mounted on at least one support frame ` connected by articulated connecting members including track lifting and lining jacks to a chassis movable on the track, which support frame is movable both vertically and laterally relative to said chassis under the action of said ; 20 jacks, in order to move said track section and to bring it into a predeter-:; mined reference position, said gripping members being provided for each side ~`~` of the track and being displaceable along said support frame, substantially ; in a straight line, transversely in relation to the chassis; and a flanged guidance wheel member for each side of the track, being mounted on the support frame so as to co-operate with the gripping member for the same side of the ; track. .
: The ad~antages of this combination are shown in detail by the des-cription and drawing which follow, but it can be easily understood that as a result of the spatial mobility provided to the gripping member, which can be 3a of any appropriate shape for engagement underneath any lateral outline of the line o~ rails or the track equipment to be gripped, it is possible to perform ~ ~
~ - 3 -':
, .
, 74~3 a gripping operation at any level relatlve to the upper surface of the rail head as well as at any lateral distance relative to the side oE said rail head and then to move the track both vertically and laterally.
The relative movements of a gripping member relative to a support frame can be obtained in an appropriate manner notably by the use of an in-termediate chassis upon which the gripping member is height-adjustably mounted.
The intermediake chassis is itself displaceably mounted on the support frame in a plane parallel to the track plane and transversely thereto.
In the same way the regulation of the vertical displacement of a gripping member relative to its intermediate chassis can be obtained by a device having multiple clamping abutments randomly interch ngeable.

~7~B3 The space betwe0n the abutmcnts is selected to adapt to the different levels of the contours to be grippedJ as will be shown hereinafter.
In an advantageous and preferred ~orm of the device according to the invention the support frame extends at least over the complete width of the railway track and supports direc~ly or indirectly the gripping and guidance wheel members of the two lines of rails of the track. This arrangement offers a number of advantages including ease of distribution of the track displacement loads on the two lines of rails.
To increase the possibilities of adaptation to track obstacles fur-10 ther the articulated connecting members connecting the support ~rame to the chassis of th0 vehicle comprise members for moving the support frame in a di-rection longitudinal to the track and/or rotating the frame in a plane substan tially parallel to the plane of the track. It is then advantageous to couple to the support frame a guide which accompanies it in its movements and prevents it turning on itself about its longitudinal axis.
In the preferred embodiment of the invention the flanged guidance wheel members of the support frame can be mounted on at least one axle parallel to the su~port frame. The axle is movable along its axis by at least one mem-ber which is e.g. extensible. The axle is connected to the support frame so as 20 to support a flanged wheel, as desired, against the side of the rail head of one or other of the lines of rails. It is then advantageous to provide the axle movement control means with a orce which is equal to half that of the lining jacks which displace said support fram0 in order to obtain ~he same lateral dis-placement force on the two lines of rails.
, It is also possible to adapt the apparatus according to the invention Z~ in its above-indicated preferred form to the different heights of the rail heads of conventional rails b~ mounting the axle of the flanged guidance wheel mem-bers in a height-adjustable ~'ashion on the support frame.

Figures 1, 2 and 3 show a support frame 1 articulated to a chassis 2 of a track working vehicle according to the invention. Articulation is via extensible articulated connecting members, or linksl which include, double acting track lifting members shown here as hydraulic jacks 3,6; track lining members shown here as hydraulic jacks 4 and 5; and positioning hydraulic jacks 7,8. Support frame 1 rests on two lines of rails 9 and 10 of a railway track, (one sleeper 11 of which is shown) via intermediate flanged guidance wheel members 12 and 13 to which reference will be made below. A guide 1~
sliding in the vehicle chassis articulated by a fork 15 in the centre of the support frame accompanies the latter in all its movements whilst preventing it from turning on itself about its longitudinal axis. The articulation points of the cylinder barrels and the piston rods o the jacks connecting the support frame to the vehicle chassis are swivelled so as to permit, f within adequate limits, complete liberty of movement for said support frame.
When the appara~us is non~operative the frame is simply guided on the rails by rail engaging means shown here as the flanged guidance wheel members 12 and 13. ~hen the apparatus is working the jacks act as desired to lift and ~ line the track. When working its movements can be broken down as follows:
- ~ 30 The vertical movements of the support frame are controlled by the .: _ 5 _ . ~ :
~V~41~;3 parallel jaclcs 3 and 6 (Figure 2).
The latera]. movements of' the ,support frame are controlled by ~he differential action of jaclcs 4 and 5 (Figure 2), The substantially hori~ontal movements of the support frame in the longitudinal direction of the railway ~,rack are controlled by the action of jacks 7 and 8 (Figure 3).
The rotation of the support frame in a plane substantially parallel to that of the track abou.t the articulat:ion of the fork 15 of the guide ~4 is controlled by the action of the jacks 7 and 8 (Figure 3). Thus by the ' ~ ~

These two figures show one o~ the gripping member~ 25 whose lower portion in the ~orm of a hook 26 can be introduced beneath the rail head 10 in order both to raise it and pu~h it laterally whilst being ~uppo~ted on i~s web.

27 and 2B of ~he i~termediate chassi~ 23 which ~or thi~ purpo~e has vertical grooves that engage pin~ 29 and-30 integral with the grlpping mamber 25. The mov~ment o~ the gripping member 25 i8 control-ed by th0 action o~ a double acting hydraulic ~ack 31 co~necting gripper m~mber end 32 remote ~rom the hook 26 to the lower end 33 to the guidance flange3 27 and 2~.

axlc 16 sliding and ~urning in bearings 17 and 18 :Eixed to the support frame 1. The~e rollers have a flange so that they can be laterally pressed against the inner face of the rail head by the combined action of two doub]e acting hydraulic jacks 19 and 20 connecting respectively the axle 16 to the bearings 17 and 18. rwo spr;ngs 21 each supported on a central shoulder of axle 16 and one of the bearings 17 and 18 serve to centre the axle 16 when the jacks 19 and 20 are released. The set of arrows shows that when it is, for exarnple, desired to move the track to the right the support frame 1 is pushed to thc right relative to the chassis 2 of the vehicle by the differential action of 10 the jacks 4 and 5. The support frame, in this movement, entrains the two gripping members 24 and 25 only one of which t25 is Figure 2) is supported on the rail ~rail 10 in Figure 2). On the other side, the rail 9 receives the force for the lateral displacement to the right via the flange of roller 12 through the jacks 19 and 20. The force is selected to be equal to half that obtained on the support frame 1 by jacks 4 and 5. I`he axle 16 may be mounted so as to be height-adjustable relative to the support frame.
Figure 6 shows schematically a track working vehicle of the tamping, levelling, lining type equipped with a device according to the invention. This vehicle whose chassis 47 rests on the track via two axles 48 and 49 is quipped 20 with tamping units 50 having vibrating tools 51 and 52 to tamp the ballast under the sleepers. The tamping units are in accordance ~ith those described in Swiss Patents 507,415 and 511,979, particularly adapted to tamping poin~s, crossing and other track equipment. It is particularly advantageous ~o install a lifting lining devica according to the invention, ths reference num~r~
being the same as in ~igure 1, on such a type of vehicle because of th~ possi-bilities of adapting said device to t~e obstacles encountered during levelling ~; and lining railwa~ equipment.
, Figures l, 2, 4 and 5 also show the possibilities of adaptation.
In Figure l shows in dotted lines the movement la of suppo~t frame 1 . j in the longitudinal direction to the track to avoid a fish plate 53 (also shown . . .
by dotted lines) which is preventing the hook of the gripping member 24 from gri~ping the rail head 9. This movement can be obtained b~ the action in B ~parallel of the two jacks 7 and 8, but parallel action is not necessar~ if ' ,, ' ' ........ ' ' ' .. '.- . . . :

`t there is no obstacle on the opposite line of rails 10. In thi3 latter ca3e it is possible to opera-te either a single jack on the side ~ere the obstacle to be avoided i~ encountered or to operate the two di~erenti~lly in the ca~e, for example, where the other side has an ob3tacle extending in the opposite direction to the first. The set of arrows in Figure 1 shows the mo~ement in par~llel. The arrows in the plan view Or Figure 3 show the differential movement causing a rotation o~ the ~upport frame about the articulation of ';'`~,7 the fork 15 of the ~ 14.
In Figure 2 the track is shown juat in front Or points when the t~o lines of rail3 54 and 55 of a second track are approaching the rails 9 and 10 of the first. The combination of the movements of the ~arious members Or the device, particularly that of the lateral movementa of the intermcdiate chasYis ; 22 on the support frame 1 with the v~tical mov~ment3 o~ the gripping m~mber 24 on ~aid chaYsis~ permits the introduction of the hook of the gripping member between th~ two rails 9 and 5S as long as the hook can paYs betwaen the heads o~ the two rails, m u3 by the normal play of ~he gripping members it is possible to lift the two lines of rails 9 and 10 up to the immediate vicinity o~ the points. m e advantage o~ this combinationis shown in Figures 4 and 5 whi¢h show that when the hook can no longer pass between the heads of the two rails 9 and S5 (~ig~re 4) for gripping the head of the line o~ rails 55 it i9 then simple to cros3 ov~r said rail S5 by means of a displac~ment to tha right of the inte~mediate chassis 22 relative to the support frame 1 combined with a vertical movement of the gripping m~mber 24 relative to the chas3is, On traversing said poi~ts ~6 (Figure 5) the combination o~ these m~vements also per~its b~ the clearance of the already described device with -1 spacer blocks (Figure 7~ to sufficientl~ lower the gripping member so that without lateral gripping it can grip th0 ~ of poin~s 56.
It should be noted that throughout the~e adapta~ions illustrated by !
Figure3 ~, ~ and 5 tra~srsing points requires no change of rails for guidance of tha device by the support rollers 12 and 13 and no change in the position oP the gripping member 25 on the line of rail 10.
These adaptatio~s ara not m~reover limitati~e and~ ~or example~ on g_ - .:
leaving points ik i8 poggible to :Eollow the rail 5S of the sf3cond track with -the gripping membex 24 (Figure ~) a3 long a~ thi~3 is permitted b~ the rree sliding l~ngth of the chassis 22 of the 8upport, ~rame 1 whilst rail 55 moves away ~rom rail 9~ Thls variant permits a longer gripping Or the combined two tracks than sho~n by Figure 2, which invol~es regripping the line Or rails 9 as soon a~ po~sible, Thus ~or ~u~mple on tr~versing a fi~h plate it is possible to grip the ~rph~ Or the rail b~tween the slespsrs with the gripping member, By this mean~ the total displac~menk Or the support frame 1 only take~ place to the right thereor~ a~3 shown in Figure 1 in dotted line3, In fact all ~ariants can be made thereto both as regards the adap-tations to the various obstacles encountered and to the known manual or auto-matic control means for obtainlng the mo~eme~t~ described without departing from the soope o~ the invention, .

~ccording to one preferrcd embodiment of the inYentiOn there is ~ provided an apparatus for the vertical and lateral movement of a sec~ion of railway track wherein gripping members operated so as to be able to grip from the outside the two lines of rails are mounted on at least one support frame ` connected by articulated connecting members including track lifting and lining jacks to a chassis movable on the track, which support frame is movable both vertically and laterally relative to said chassis under the action of said ; 20 jacks, in order to move said track section and to bring it into a predeter-:; mined reference position, said gripping members being provided for each side ~`~` of the track and being displaceable along said support frame, substantially ; in a straight line, transversely in relation to the chassis; and a flanged guidance wheel member for each side of the track, being mounted on the support frame so as to co-operate with the gripping member for the same side of the ; track. .
: The ad~antages of this combination are shown in detail by the des-cription and drawing which follow, but it can be easily understood that as a result of the spatial mobility provided to the gripping member, which can be 3a of any appropriate shape for engagement underneath any lateral outline of the line o~ rails or the track equipment to be gripped, it is possible to perform ~ ~
~ - 3 -':
, .
, 74~3 a gripping operation at any level relatlve to the upper surface of the rail head as well as at any lateral distance relative to the side oE said rail head and then to move the track both vertically and laterally.
The relative movements of a gripping member relative to a support frame can be obtained in an appropriate manner notably by the use of an in-termediate chassis upon which the gripping member is height-adjustably mounted.
The intermediake chassis is itself displaceably mounted on the support frame in a plane parallel to the track plane and transversely thereto.
In the same way the regulation of the vertical displacement of a gripping member relative to its intermediate chassis can be obtained by a device having multiple clamping abutments randomly interch ngeable.

~7~B3 The space betwe0n the abutmcnts is selected to adapt to the different levels of the contours to be grippedJ as will be shown hereinafter.
In an advantageous and preferred ~orm of the device according to the invention the support frame extends at least over the complete width of the railway track and supports direc~ly or indirectly the gripping and guidance wheel members of the two lines of rails of the track. This arrangement offers a number of advantages including ease of distribution of the track displacement loads on the two lines of rails.
To increase the possibilities of adaptation to track obstacles fur-10 ther the articulated connecting members connecting the support ~rame to the chassis of th0 vehicle comprise members for moving the support frame in a di-rection longitudinal to the track and/or rotating the frame in a plane substan tially parallel to the plane of the track. It is then advantageous to couple to the support frame a guide which accompanies it in its movements and prevents it turning on itself about its longitudinal axis.
In the preferred embodiment of the invention the flanged guidance wheel members of the support frame can be mounted on at least one axle parallel to the su~port frame. The axle is movable along its axis by at least one mem-ber which is e.g. extensible. The axle is connected to the support frame so as 20 to support a flanged wheel, as desired, against the side of the rail head of one or other of the lines of rails. It is then advantageous to provide the axle movement control means with a orce which is equal to half that of the lining jacks which displace said support fram0 in order to obtain ~he same lateral dis-placement force on the two lines of rails.
, It is also possible to adapt the apparatus according to the invention Z~ in its above-indicated preferred form to the different heights of the rail heads of conventional rails b~ mounting the axle of the flanged guidance wheel mem-bers in a height-adjustable ~'ashion on the support frame.

Figure 6 shows a tamping, levelling and lining track working vehicle equipped with the device according to the invention.
Figure 7 is a detailed elevation of the operation of a gripping member according ~o section II-II of Figure 8.
~igure 8 is a plan view of ~igure ~.
Figures 1, 2 and 3 show a support frame 1 articulated to a chassis 2 of a track working vehicle according to the invention. Articulation is via extensible articulated connecting members, or linksl which include, double acting track lifting members shown here as hydraulic jacks 3,6; track lining members shown here as hydraulic jacks 4 and 5; and positioning hydraulic jacks 7,8. Support frame 1 rests on two lines of rails 9 and 10 of a railway track, (one sleeper 11 of which is shown) via intermediate flanged guidance wheel members 12 and 13 to which reference will be made below. A guide 1~
sliding in the vehicle chassis articulated by a fork 15 in the centre of the support frame accompanies the latter in all its movements whilst preventing it from turning on itself about its longitudinal axis. The articulation points of the cylinder barrels and the piston rods o the jacks connecting the support frame to the vehicle chassis are swivelled so as to permit, f within adequate limits, complete liberty of movement for said support frame.
When the appara~us is non~operative the frame is simply guided on the rails by rail engaging means shown here as the flanged guidance wheel members 12 and 13. ~hen the apparatus is working the jacks act as desired to lift and ~ line the track. When working its movements can be broken down as follows:
- ~ 30 The vertical movements of the support frame are controlled by the .: _ 5 _ . ~ :
~V~41~;3 parallel jaclcs 3 and 6 (Figure 2).
The latera]. movements of' the ,support frame are controlled by ~he differential action of jaclcs 4 and 5 (Figure 2), The substantially hori~ontal movements of the support frame in the longitudinal direction of the railway ~,rack are controlled by the action of jacks 7 and 8 (Figure 3).
The rotation of the support frame in a plane substantially parallel to that of the track abou.t the articulat:ion of the fork 15 of the guide ~4 is controlled by the action of the jacks 7 and 8 (Figure 3). Thus by the ' ~ ~

These two figures show one o~ the gripping member~ 25 whose lower portion in the ~orm of a hook 26 can be introduced beneath the rail head 10 in order both to raise it and pu~h it laterally whilst being ~uppo~ted on i~s web. Thi~

axlc 16 sliding and ~urning in bearings 17 and 18 :Eixed to the support frame 1. The~e rollers have a flange so that they can be laterally pressed against the inner face of the rail head by the combined action of two doub]e acting hydraulic jacks 19 and 20 connecting respectively the axle 16 to the bearings 17 and 18. rwo spr;ngs 21 each supported on a central shoulder of axle 16 and one of the bearings 17 and 18 serve to centre the axle 16 when the jacks 19 and 20 are released. The set of arrows shows that when it is, for exarnple, desired to move the track to the right the support frame 1 is pushed to thc right relative to the chassis 2 of the vehicle by the differential action of 10 the jacks 4 and 5. The support frame, in this movement, entrains the two gripping members 24 and 25 only one of which t25 is Figure 2) is supported on the rail ~rail 10 in Figure 2). On the other side, the rail 9 receives the force for the lateral displacement to the right via the flange of roller 12 through the jacks 19 and 20. The force is selected to be equal to half that obtained on the support frame 1 by jacks 4 and 5. I`he axle 16 may be mounted so as to be height-adjustable relative to the support frame.
Figure 6 shows schematically a track working vehicle of the tamping, levelling, lining type equipped with a device according to the invention. This vehicle whose chassis 47 rests on the track via two axles 48 and 49 is quipped 20 with tamping units 50 having vibrating tools 51 and 52 to tamp the ballast under the sleepers. The tamping units are in accordance ~ith those described in Swiss Patents 507,415 and 511,979, particularly adapted to tamping poin~s, crossing and other track equipment. It is particularly advantageous ~o install a lifting lining devica according to the invention, ths reference num~r~
being the same as in ~igure 1, on such a type of vehicle because of th~ possi-bilities of adapting said device to t~e obstacles encountered during levelling ~; and lining railwa~ equipment.
, Figures l, 2, 4 and 5 also show the possibilities of adaptation.
In Figure l shows in dotted lines the movement la of suppo~t frame 1 . j in the longitudinal direction to the track to avoid a fish plate 53 (also shown . . .
by dotted lines) which is preventing the hook of the gripping member 24 from gri~ping the rail head 9. This movement can be obtained b~ the action in B ~parallel of the two jacks 7 and 8, but parallel action is not necessar~ if ' ,, ' ' ........ ' ' ' .. '.- . . . :

`t there is no obstacle on the opposite line of rails 10. In thi3 latter ca3e it is possible to opera-te either a single jack on the side ~ere the obstacle to be avoided i~ encountered or to operate the two di~erenti~lly in the ca~e, for example, where the other side has an ob3tacle extending in the opposite direction to the first. The set of arrows in Figure 1 shows the mo~ement in par~llel. The arrows in the plan view Or Figure 3 show the differential movement causing a rotation o~ the ~upport frame about the articulation of ';'`~,7 the fork 15 of the ~ 14.
In Figure 2 the track is shown juat in front Or points when the t~o lines of rail3 54 and 55 of a second track are approaching the rails 9 and 10 of the first. The combination of the movements of the ~arious members Or the device, particularly that of the lateral movementa of the intermcdiate chasYis ; 22 on the support frame 1 with the v~tical mov~ment3 o~ the gripping m~mber 24 on ~aid chaYsis~ permits the introduction of the hook of the gripping member between th~ two rails 9 and 5S as long as the hook can paYs betwaen the heads o~ the two rails, m u3 by the normal play of ~he gripping members it is possible to lift the two lines of rails 9 and 10 up to the immediate vicinity o~ the points. m e advantage o~ this combinationis shown in Figures 4 and 5 whi¢h show that when the hook can no longer pass between the heads of the two rails 9 and S5 (~ig~re 4) for gripping the head of the line o~ rails 55 it i9 then simple to cros3 ov~r said rail S5 by means of a displac~ment to tha right of the inte~mediate chassis 22 relative to the support frame 1 combined with a vertical movement of the gripping m~mber 24 relative to the chas3is, On traversing said poi~ts ~6 (Figure 5) the combination o~ these m~vements also per~its b~ the clearance of the already described device with -1 spacer blocks (Figure 7~ to sufficientl~ lower the gripping member so that without lateral gripping it can grip th0 ~ of poin~s 56.
It should be noted that throughout the~e adapta~ions illustrated by !
Figure3 ~, ~ and 5 tra~srsing points requires no change of rails for guidance of tha device by the support rollers 12 and 13 and no change in the position oP the gripping member 25 on the line of rail 10.
