Definitions

  • This invention relates to a switch system utilizing a pivoting frog and laterally displaceable rails at the entrance to the switch wherein provision is made for longitudinally non-pivoting displaceable rails ahead of the entrance to the switch and ahead of the frog point.
  • the rails ahead of the switch entrance abut the inside of the main track rails.
  • the longitudinally displaceable rails ahead of the frog point abut, in one case the outside or perferably the inside of the inside rail of the branch track rails, and, in the other case, abut the outside or preferably the inside rail of the main track rails.
  • the invention relates to a switch for rail vehicles, which has a pivoting frog and in which the frog point can be joined in an end-to-end relationship to either of the two rails which are non-pivotally disposed within the frog and which have a flangeway between them, and wherein the main track rails and the branch track rails are separate from the main track rails ahead of the switch, are in the form ofa laterally pivotable deflection unit, and can be joined in an end-to-end relationship to the rails lying ahead of the switch entrance.
  • the rails of the main and branch tracks are separate from the rails preceding the switch entrance.
  • the ends of the rails are blunt.
  • the rail sections preceding the switch entrance are pivotable laterally, but they are not movable longitudinally.
  • gaps are provided between the blunt ends of the rails to permit the rails to pivot. These gaps cause bumps and increased wear as the car wheels pass over them. See US. Pat. Nos. 2,641,690 and 3,3l7,725.
  • the point of the tongue is not located at the beginning of the are, but is set back towards the end of the switch. This results in an abrupt angle of entrance which is perceived on the one hand as a jerk when it is struck and on the other hand through the increased wear which it causes.
  • the rails in the track are canted, at an inclination, for example, of 1:20 or 1:40.
  • a canting of the rails and tongues can be achieved only at an economically unfeasible cost.
  • the frog of the switch has a stationary point.
  • frogs with movable points or movable guardrails are used.
  • This invention is directed to an improvement in a switch for rail vehicles which switch comprises a pivot-- ing frog in which the frog point is adaptable to be joined in an end-to-end relationship with either of the rails non-pivotingly disposed within the frog which rails form a flangeway wherein the main track rails and the branch track rails are separate from the main track rails ahead of the switch and means are provided for pivotingly effecting lateral deflection of the main track rails and branch track rails at the entrance to said switch, said improvement comprising longitudinally displaceable non-pivoting rails positioned ahead of the switch entrance, which rails are adaptable on one end thereof to abut in end-to-end relationship a pair of pivotingly laterally deflectable rails deflectable by said means for pivotingly effecting lateral deflection and on the other end to abut the inner edge of the main track rails; longitudinally displaceable non-pivoting rails positioned ahead of the switch entrance, which
  • the middle rail of the branch track rail and the middle rail of the main track rail are both tapered outwardly to receive against their inside surfaces the longitudinally displaceable rails ahead of the frog point, which rails are guided into position against the inner edge of these inside rails.
  • the invention utilizes longitudinally displaceable non-pivoting rails both ahead of the switch entrance and ahead of the frog point to engage pivoting rails on one side with stationary rails on the other.
  • Such longitudinally displaceable rails avoid unnecessary gaps or the like at switch entrances and exits.
  • the rails are moved by suitable servo motors which are coupled by means of spindles for racks and pinions to these longitudinally displaceable rails for rail extensions. They are suitably held in place against the inside ends of the nonpivoting rails by ciamping means which can be actuated by hydraulic, pneumatic, mechanical or electrical means to secure the rail in its proper position. Movement of the rails is permitted by release of clamping means disposed against the flange of the rails. When the rail is set in its new position the clamping means are once again actuated to secure the rail against lateral movement. 1
  • securement of the ends of the longitudinally displaceable non-pivoting rails to the pivoting rails at the entrance to the switch and at the frog point is provided by an angle junction whereby the ends of the rails are caught at an angle to mesh with the corresponding rails to provide a junction which inhibits lateral displacement of the rails at said junction.
  • the longitudinally displaceable non-pivoting rails are provided with a tenon adaptable to enter a mating mortise or on the end of the pivoting rail to provide further securement against lateral displacement at the junction.
  • the rails of the branch track can be increasingly depressed or, on the other hand, can be increasingly elevated to provide against further side sway at the switch entrance.
  • the rails in the switch can be disposed in an inclined position, as more fully discussed below.
  • the special advantages of the invention consist in the robust construction, which can be designed in accordance with the dynamic conditions involved.
  • Such switch system readily permits canting of the rails and the elevation or depression of the branch track in respect of the main track rails.
  • all of the rails within the switch and the frog point can consist of standard, unthinned rail cross-sections and the rails, while being tightly held on the saddles, can be clamped in the desired end position. This is especially desirable in the case of switches with great radii of curvature for high speeds.
  • FIG. 1 is a schematic plan view of a switch.
  • FIG. 2 shows the deflection unit at the switch entrance and the rail extensions leading to the switch entrance, in a plan view.
  • FIG. 3 shows the rail extension in a cross section taken along line II of FIG. 2.
  • the clamping means 32 are shown as if the view, in that respect, were an end view.
  • FIG. 4 shows the deflection unit at the switch entrance in a cross section along the line II-II of FIG. 2.
  • FIG. 5 is an enlarged plan view of an angled rail junction at the switch entrance.
  • FIG. 6 shows the frog of the switch with the rail extensions facing the frog point and one of said extensions 13 engaged with a pivoted rail.
  • FIG. 7 shows a cross-section taken along line III-III of FIG. 6 through the rail extensions ahead of the frog.
  • FIG. 8 is a sectional elevation taken along line lV-IV of FIG. 1, illustrating the canting of the rails at line IV-IV of FIG. 1
  • FIG. 9 is a sectional elevation taken along line VV of FIG. 1, illustrating the lowering or raising of the branch rails in respect of the main track rails.
  • FIG. 9 is also a sectional view taken along the line VI-VI of FIG. 1 illustrating the lowering or raising of the branch rails in respect of the main track rails.
  • FIG. 9 can show both embodiments, i.e., when the branch rails are lowered or when the branch rails are raised with respect to the main track rails.
  • the switch represented in FIG. 1 consists of the straight-running main track 1 and the branch track 2' departing from the main track 1.
  • the rails 3 and 4 of the main track 1 and the rails 5 and 6 of the branch track 2 are invariable in their spacing from one another and are locked together in a laterally pivotable deflection unit 7.
  • Ahead of the switch entrance lie two tongue-shaped rail extensions 8 and 9 which are longitudinally displaceable on slide plates and which lie against the inner sides of the outwardly bent or tapered rail ends 10 and 11 of the main track 1 located ahead of the switch entrance.
  • These rail extensions 8 and 9 are non-pivotable.
  • Servo motors 29, 30 and 31 are coupled, by means of spindles or racks and pinions, to the rail extensions 8, 9, 13 and 14 for the longitudinal displacement thereof.
  • the rail extensions 8, 9, 13 and 14 are laterally guided by the rail end portions l0, 11, 15 and 16 engaging them and by the dogs of clamping means 32, 33, 34 which are affixed to the corresponding slide plates 60 and engage the rail flanges.
  • the rail flanges have step-like guiding edges 35, 36, 37, running parallel to the rail end portions 10, 11, 15 and 16.
  • the clamping means 32, 33 and 34 have hydraulically actuated dogs engaging the rail flanges, as shown in detail in FIGS. 3 and 7.
  • the rails 3 to 6 are mounted with invariable spacing on a plurality of saddles 38, 39, arranged in series, only one pair of saddles being represented in the drawing.
  • Two adjacent saddles 38, 39, are joined together with the invariable spacing by a connecting bar 40, with provision for adjustment.
  • the saddles 38 and 39 are mounted for lateral displacement on slide plates 41 and 42 which remain stationary. In the rail junction area, plates 41 and 42 are widened to provide better support for the rail junctions.
  • the saddles 38 and 39 are guided in the guiding means 43, 44, 45, 46, 47, 48, 49 and 50 affixed to slide plates 41 and 42 and can be locked in place by means of the hydraulically actuated clamping means 61, 62, 63, 64, 65, 66, 67 and 68. Details of the deflection unit 7 are shown in FIG. 4.
  • a servo motor 51 which can be coupled to saddles 38 and 39 through a threaded shaft or rack-and-pinion drive, for example, serves for the shifting of the deflection unit 7.
  • the clamping means can be pneumatically, mechanically or electrically actuated.
  • the frog point 12 is, like the deflection unit 7, mounted on a plurality of saddles 52 arranged in series, which are guided by guiding means 69, 70, 71 and 72 and are laterally displaceable on stationary slide plates 54 by means of a servo motor 53, and which can be locked in place by hydraulically actuated clamping means 55, 56, 57, and 58 engaging the saddle.
  • the saddle 52 is widened for better support of the rail junction.
  • the switch is operated in the following manner.
  • the rail extensions 8, 9, 13, 14 and rails 3 to 6 as well as frog point 12 are again locked in place by the actuating of the clamping means 32 to 34, 61 to 68, and 69 to 72, hydraulically.
