Description

Nov. 26, 1963 F. PLASSER ETAL MOBILE TRACK LEVELING MECHANISM Filed Jan. 28, 19460 N um QN INVENTORS, H196# Z pL 4558 giss 72s wenn United States Patent O 3,111,907 MOBILE TRACK LEVELING MECHANISM Franz Plasser and Josef Theurer, both of Johannesgasse 3, Vienna, Austria Filed Jan. 28, 1960, Ser. No. 5,211 6 Claims. (Cl. 104-7) The present invention relates to a mobile track leveling mechanism for automatically aligning two track rails in a pre-determined Vertical plane perpendicular to the track.
In laying tracks and determining the desired relative position of the two rails dening the track plane, one of the rails is usually first fixed in the desired position and the other rail is then lifted in relation to the fixed rail until the desired track level is obtained. In this operation, the angle of the track plane has usually been visually observed by reading a level and the thus obtained information was used by the operator of the track lifting means. The control of the track lifting means in dependence of the reading of the level is time-consuming and requires considerable effect and attention. Accordingly, it has not always been precisely performed and it was also difficult to observe the level while raising the one rail in accordance with the level reading so that lifting of the rail may be stopped precisely at the moment when the level indicated the desired inclination of the track plane.
It is the primary object of the present invention to provide an automatic control of the rail lifting means in response to the angle of the track plane and to stop the operation of a rail jack lifting one of the rails as soon as the relative pos-ition of this one rail to the other, fixed rail of the track is such that the desired track plane is obtained, for instance when the plane is horizontal in a straight section of the track.
This and other objects are accomplished in accordance with this `invention by pivotally and swingably supporting a pendulum on a frame of a car having wheels for mobility on the track and :also supporting means for lifting either of the track rails. The pendulum carries an electrical contact element which, upon swinging of the pendulum, engages an electrical contact element forming part of an electrical circuit and closes the circuit, the circuit being connected to the actuating system for operation of the lifting means and the closed circuit energizing means for discontinuing the operation. The pendulum swings in response to a change in the relative position of the rail being lifted to the other rail which remains lixed.
In accordance with one preferred embodiment of the invention, the electrical contact element of the electrical lcircuit is adjustably mounted on the car frame and s-ince it is advantageous to have the mechanism operable for lifting either rail, i.e. for swinging the pendulum in either direction to close the circuit, one electrical contact element is preferably mounted on each side of the pendulum.
Track planes are preferably inclined on curves so that it is desirable to make the mechanism responsive not only to the horizontal levelling of the track plane but to a pre-determined angle thereof, For this purpose, the contact element or each element of the electrical circuit may be mounted on a carrier which is pivotally mounted on the car frame, 1an arcuate guide being provided for adjusting the position of the carrier in relation to the frame and the contact element of the pendulum, the adjustment of the carrier in relation to the perpendicular determining the track plane angle which will cause closure of the circuit. Preferably, the pendulum and the contact element carrier or carriers are supported on a common pivot means and, when two carriers are used, one is always suiciently pivoted away from the pendulum as to be inoperative.
ICC
The control mechanism of the present invention is particularly useful in connection with pressure fluid operated jacks for lifting rails. In this case, the closed electrical circuit of the mechanism energizes a means, for instance an electromagnet, for closing a valve cutting off pressure fluid from the jack.
The `above and other objects, advantages and features of the present invention will appear more fully from the following detailed description of a specific embodiment thereof, provided merely for purposes of illustration and without in any Way limiting the scope of the invention.
The single FIGURE of the accompanying drawing schematicaily shows a side 'View of an automatic track position responsive mechanism for actuating a track lifting device according to this invention.
'Ihe track lifting means forms no part of the present invention, apart from its combination with the novel control mechanism for its operation, and may take any desired form. For instance, the track lifting means may be the same or similar to those disclosed in U.S. Patent No. 2,734,463 or in our U.S. Patent No. 2,847,943. Suitable jacking means is also disclosed in our copending applications Serial No. 815,979, liled May 26, 1959, and abandoned in favor of continuation :application Serial No. 68,042, now Patent No. 3,103,182, dated September 10, 1963, and Serial No. 815,982, led May 26, 1959, now Patent No. 3,101,676, dated August 27, 1963. Since the track lifting means per se forms no part of the invention, it has been illustrated only inasmuch as it is connected to the novel control mechanism therefor.
Referring now to the drawing, there is shown a triangular frame l of a track lifting car which moves on wheels 2 on rails 3', 3 of a railroad track, the rails being mounted on ties 4 which rest on ballast 5. A pivot pin 6 is journaled in frame 1 at its apex to constitute a pivoting means for the pendulum 7 which hangs on the pin. The pivoting means also carries tWo pivotally adjustable contact carriers 8 and 9 and which have bearing sleeves 29 pivotally mounted on pin 6 so that the contact carriers may be adjusted in any desired angular position.
Pendulum 7 supports a two-faced contact element 10 which is arranged for making contact with contact element 11 on carrier 8 or contact element 12 on carrier 9.
The Contact carriers have pie-shaped lugs 8', 9 delining arcuate slots 14 serving as guides for wing screws 13 which threadedly engage frame 1. The slots and screws constitute means for adjusting the angular position of .the contact carriers in relation to the pendulum, a respect-ive one of screws 13 being loosened when an adjustment of its associated carrier is desired and the screw being tightened again when the scale 15 indicates the desired angular position.
While the lifting means per se forms no part of this invention `the illustrated hydraulic jack is that of our application Serial No. 815,982, now Patent No. 3,101,676, this jacking means including cylinder 16, piston 17 with its piston rod 1S and a foo-t piece 19' constituted by a disc which is pivotally mounted at the end of the piston rod and engages the ground. Ille lift cylinder 16 contains `a compression spring 20 tending to urge the piston upwardly when the jacking means is in its inoperative position. A pressure fluid line 21 is in communication with the other cylinder chamber and when it supplies pressure fluid to this chamber, the piston is urged down against the 'bias of spring 20 to operate the jacking means by pressing the Afoot piece 19 against the ground. The lift cylinder 16 has an upwardly extending lug to support the cylinder pivotally on bracket 1 which extends laterally outwardly from upright 1 forming part of the supporting frame of the mobile track leveling mechanism. At its lower end, the lift cylinder carries a laterally eX- 3 tending rail lift member constituted by a platform 16' xedly attached to the cylinder and adapted to subtend and support rail 3' when the jacking means is in the illustrated operative position.
As shown, the supply of pressure lluid, for instance hydraulic liquid, from a pump (not shown) to conduit 21 may be cut off by valve 23. In the illustrated embodiment, the valve means is constituted by a slide valve which is normally hel-d in open position by a compression spring 24 and which may be closed electro-magnetically when the winding 25 of an electromagnet is energized.
The electric current source is indicated by storage battery 28, the circuit for the electromagnetic winding 25 being constituted `by conductor 27 connected to contact elements 11, 12 and by conductor 26 connected to contact element 10 of pendulum 7. The circuit is closed and the winding 25 is energized when contact element l contacts either contact element 11 or 12, thus closing valve means 23, cutting off further pressure fluid supply to lift cylinder 16 and ending the lifting operation.
The mechanism operates as follows:
Assuming the track lifting car is positioned at a straight section of the track which requires the two rails to be aligned in a horizontal plane. In this case and after the rail 3 has been Xed in the desired position of the track, the contact carrier 8 is pivotally adjusted so that its pointer is aligned with the calibration on scale 15 while Contact carrier 9 is moved sufliciently out of the way of pendulum 7 to remain out of contact therewith during the lifting operation, as illustrated.
The track lifting means is applied only to rail 3" which is to be brought to a level with rail 3'.
As long as the rail 3 remains below the level of fixed rail 3', pendulum 7 swings to the right (as seen in the drawing) and its contact element 1t) is accordingly out of contact with either contact element 11 or l12, contact carrier 9 having been moved out of the way since it is not required for this operation. The pressure fluid supply system is now actuated by the operator to supply pressu-re fluid to lift cylinder 16 through open valve 23, such pressure fluid supply systems -a-lso being known per se, for instance from our Patents Nos. 3,101,676 and 3,103,182.
As soon as the track has been levelled, i.e. rails 3 and 3 lie in the same horizontal plane, as illustrated, pendulum 7 assumes a perpendicular position and its contact element makes contact with contact element 11, thus closing the electric circuit 26, 27 and supplying current from storage ybattery 28 to winding 25. This energizes the electromagnet and instantly closes valve 23 to interrupt the lifting operation and to hold rail 3 in the desired position wherein it may be fixed in a suitable manner, for instance by tamping ballast under tie 4.
After the track has been levelled, the hydraulic jack is withdrawn in a manner known, for instance, from our above-mentioned applications, and the track lifting car may be moved to the next track section which requires correction.
At track curves where itis desired to impart an inclination from the horizontal to the track, the desired angle of inclination can be adjusted by suitably positioning contact carrier 8 or 9 according to scale 15. In each instance, only that contact carrier is operative which delirnits the movement of pendulum 7 during t-he lifting of the respective rail; the other carrier is always moved out of the range of the pendulum to avoid any interference with the control mechanism.
Many variations and modifications of the mechanism may occur to the skilled in the art, particularly after benefiting from our teaching, an essential feature being the control of the inclination of the transverse plane of `the track by a pendulum mechanism automatically c0ntrolling a track lifting means. The scope of the invention is dened in the appended claims.
