  • the tool is used in the type of track renewal apparatus more fully described and claimed in our copending application Ser. No. 849,406, filed Aug. 12, 1969, under the title Mobile Track Maintenance Apparatus.
  • the car frame has swivel trucks 2, 2 for mobility on track rails 3, 3 which rest on ties 4.
  • a separate tool is associated with each track rail and each tool is mounted for movement in the direction of track elongation on guide rail means 8 and is glidable therealong by chain drive 9, the carriage 10 of the tool being vertically adjustably so that it may be lifted off the track in case of obstructions, all as described in our application filed on even date.
  • the tool is within sight of the operator in cabin 5, and each tool associated with a respective rail is independently movable in the direction of track elongation and transversely thereof for ready use in track curves.
  • the track working tool particularly described herein is a power-driven wrench for driving rail fastening bolts but it will be obvious to those skilled in the art that it could be a spike driver or puller where spikes are used instead of bolts to fasten the rails to the ties.
  • the tool may also be an oiler for track fastening elements or a tie drill, a tie placer or the like.
  • the underside of the car frame platform carries a pair of guide rails 8, 8 vertically above each rail and extending in the direction of track elongation, each IOIOIS 0700 either direction. It supports a pivotal arm 16 whose'one end is mounted on the carrier plate by means of pivot bolt 14 and whose other end carries rollers 17 running in an arcuate guide 18.
  • the arm 16 is laterally pivotal by pressure fluid drive 15 schematically shown in FIG. 4.
  • a vertical guide column 19 projects downwardly from carrier arm 16 and has a pair of studs 19' to which the tool carriage 10 is glidably attached.
  • a pressure fluid drive 20 is mounted on the guide column 19 and has one end connected to the carriage 10 for vertically moving the carriage, the carriage also being pivotal in a horizontal plane about the guide column so that the tool may be adjusted to an oblique position of a tie.
  • the tool carriage 10 runs on the track rails 3 by means of rimmed rollers 21 which serve to guide the tool along the rail, the lateral pivoting of carrier arm 16 serving to press the tool carriage 10 either against the inner or the outer edge of the rail head, preferably against the inner rail head edge.
  • the entire carriage with its rollers may be lifted off the track along column 19 by means of pressure fluid drive 20.
  • a guide housing 23 on carriage 10 encloses two tool holders 22 mounted in the housing side by side for operation on either side of the rail 3.
  • Each toolholder carries on top a tool drive motor 22' and a downwardly extending tool 27.
  • Yielding, resilient or elastic bearings elastically support the tool holders with their tools in the housing and in relation to each other so that the tools may be in at least approximate registration of alignment with the rail fastening element 25 on which work is to be done.
  • the tool is a power driven wrench and the rail fastening element is a rail bolt to be fastened or loosened by the wrench.
  • the toolholder bearings illustrated in FIGS. 3 to are coil springs 24 mounted between the walls of housing 23 and the toolholders as well as between the toolholders.
  • the elasticity or resilience of the coil springs may be adjusted by set screws acting on the springs.
  • the bearings consist of elastic inserts 24, for instance of rubber, arranged between the tool holders as well as between a respective toolholder and an adjacent wall of housing 23.
  • FIG. 4b Another and functionally equivalent modification of an elastic bearing is shown in FIG. 4b where pressure fluid operated cylinders 24 are mounted between the tool holders and a respective toolholder and an adjacent wall.
  • the above-described elastic bearings for the toolholders 22 extend transversely of the track to permit resilient movement of the toolholders in this direction. However, it may be useful to impart such resilient movement to the toolholders also in the direction of track elongation, for which purpose additional elastic or yielding bearings for the toolholders may extend in the latter direction. Such additional bearings are illustrated in FIGS. 3 and 4 in the form of coil springs 26 mounted between the front wall of housing 23 and the toolholders 22.
  • the coil spring bearings may be readily exchanged for springs of different resiliency and/or length to change the basic position of the toolholders in the housing.
  • the shaft of wrench 27 is rotatable by motor 22' in either direction to operate the wrench when it engages bolt head 25.
  • This wrench shaft is vertically movable in the toolholder by means of the pressure fluid drive 20 also used to move the tool carriage vertically.
  • the free outer end of the piston rod of drive is linked to two-armed levers 28 which act upon the rotatable wrench shafts, which are vertically movably mounted in the toolholders 22, against the pressure of compression springs 29.
  • the shaft of tool 27 ends in a cup-shaped head which tapers conically outwardly towards the bolt head so that, when the tool is lowered into operating position, the tool head will be automatically centered on the bolt head in view of the elastic mounting of the toolholder which will readily yield in all directions as the tool head seeks secure engagement with the bolt head.
  • a pair of stops are mounted on carriage 10 alongside the rail 3, the stop illustrated in FIG. 3 being a twoarmed lever"32 which is pivoted to the carriage at 31 for movement in a vertical plane parallel to the track.
  • the stops may be reciprocated in this plane by a pressure fluid drive 30 so that the lower end of the stop levers engage a part of the rail fastening, for instance the tie plate or the rail bolt or spike, when the machine advances during the track work, to the left in the drawing.
  • the tool carriage will be held in fixed position during tool operation without interfering with the continuous forward movement of the car frame 1 since the tool carriage is movable in respect to the car frame in the direction of track elongation.
  • the tool carriage While the car frame continuously advances with the train which is used to renew the track, the tool carriage may be periodically stopped to enable the tool to do its work, and is then more rapidly moved forwardly on the car frame by its chain drive to the next working station.
  • the stop levers 32 position the tool carriage 10 so that the tools will be in approximate vertical alignment with the rail fastening elements on which they are to work, whereupon the tools are lowered and automatically centered on the rail fastening elements due to the elastic mounting of the toolholders.
  • the position of the stops 32 in the direction of track elongation is adjustable, for instance by changing the effective length of the piston rod of the drive 30, so that the stops may engage selected parts of the rail fastening.
  • Such adjustment may be effected, for example, by using a telescoping piston rod whose length is adjustable.
  • the tool holders 22 are separately and independently mounted in the housing 23 on a pair of guide columns 19, 19.
  • Eachtoolholder has its own elastic bearing 24 so that each toolholder is laterally yieldingly positioned between the sidewalls of the housing 23. There is no elastic connection between the toolholders, as in the previously described embodiments.
  • the coil springs 24 bear against exchangeable setscrews mounted in the housing sidewall opposite to the sidewall wherein the springs are mounted so that the resiliency of the tool holder bearings may be varied at will. This makes it possible accurately to adjust the position of the tool 27 in relation to the rail fastening means on which it is to work.
  • the tool carriage housing 23 may also carry a vertically adjustable jack shoe serving to press down and fixedly hold a tie 4 during the operation of the tool 27 on the rail fastening element 25.
  • the illustrated jack includes a pressure fluid operated cylinder 34 and a piston rod 33.
  • FIGS. 7a and 7b Modifications of elastic bearings for tool holders 22 are shown in FIGS. 7a and 7b.
  • the toolholder 22 is carried by a pair of leaf springs 24a.
  • an annular bearing of elastic material, such as rubber, holds the toolholder in yielding relationship to the walls of housing 23.
  • FIGS. 8 and 9 illustrate the use of the present invention in relation to a machine which comprises a carriage frame 35 running on the track rails 3, 3 by means of wheels 35'.
  • a central drive 36 is connected to gear boxes 37 positioned on the carriage frame vertically above rails 3 for operating the tools associated with each rail.
  • the toolholders 38 are universally yieldably mounted on carriage frame 35, the tool shafts 39 extending from the tool holders into gear boxes 37 for rotation by common drive 36.
  • a common tool carrier constituted by a crossbeam 40 extends transversely of the track over both rails, the common tool carrier being yieldingly suspended on the carriage frame 35 by means of springs 35'.
  • the tool carrier defines slots 41 extending in a direction transversely of the track and each receiving a pair of the toolholders 38 which are vertically adjusted with the common tool carrier 40.
  • Elastic toolholder bearing 42 illustrated as coil springs, mount the toolholders in the slots 41 so that the same are yieldingly positioned in a direction transverse to the track.
  • a common, transversely extending guide piece 43 is mounted in vertical alignment with each rail for each pair of tools associated with a respective rail 3.
  • a bolt M projects from each toolholder 38 into a horizontal slot in the guide piece 43.
  • the bolts carry nuts 45 which may be tightened so that each toolholder may be fixed in a desired lateral position in respect to the associated rail after the bolt has been moved in the horizontal slot of the guide piece.
  • the lateral position of the guide piece 43 in respect of rail 3 is controlled by rail sensing rod 46 whose upper end is linked to carriage frame 35 and whose lower end yieldingly engages the inner edge of the rail head, as best seen in FIG. 8, under the bias of spring 47 connecting an intermediate point on the rod to the carriage frame.
  • the carriage frame may have a seat 48 for an operator.
  • the common tool carrier 40 is rotatably journaled on a vertical support column 49 so that the tool carrier may be rotated into desired operating positions of the tools.
  • the tool carriage of FIG. 10 is generally similar to that of FIGS. 3 to 5 but the vertical adjustment of tools 27 is controlled by a stop lever 50.
  • the illustrated position is the initial position of tool 27 before its head engages the head of the rail fastening element.
  • the tool is lowered by distance x by means of drive in the manner fully described in connection with FIGS. 3 to 5.
  • the piston of drive 20 is raised to lift the tool until the stud 51 on'the lower end of the piston rod of drive 20 engages a cooperating recess in stop lever 50. This is repeated after each tool operation.
  • the stop lever 50 is pivoted out of the illustrated operating position to the right, as seen in the drawing, by means of pressure fluid drive 52. With the stop lever out of the path of stud 51, the latter is free to move on to engage the carriage housing 23 so that the drive 20 will lift the housing and the carriage 10, which is fixedly connected thereto, off the track.
  • a machine for working on track rail fastening elements and mounted for mobility on the track in the direction of track elongation comprising 1. a tool carriage,
  • the toolholder and guide cooperating to maintain the tool at a distance from an associated one of the track rails which is secured by the track rail fastening elements on which the tool is to work
