Definitions

  • ABSTRACT A rail fastener includes a spring clip having a longitudinal section with one end applying downward pressure upon a rail base as the opposite end, formed with a vertical pivot arm, bears downwardly toward a crosstie. Deflection of the control portion of the longitudinal section is achieved upon the insertion of a transverse pin through spaced apart sidewalls of an anchor member underlying and adjacent the lateral edges of the spring clip.
  • This invention relates generally to railway devices, and more particularly, to an improved rail fastener including an anchor member fixedly attached to a crosstie and provided with means cooperating with a removable spring clip to position and retain the clip in a deflected stressed condition with one end thereof bearing upon the upper surface of a rail base flange.
  • an improved spring clip rail fastener comprising an L-shaped spring clip having a pivot section directed toward the upper surface of the crosstie on the one end and a rail base engaging section on the other end.
  • the spring clip is retained in working position by means of a unique anchor member having insertable means for downwardly deflecting the central body section of the spring clip such that an extremely high degree of pressure is exerted by the under surface of the rail engaging section upon the upper surface of the rail base flange.
  • one of the primary objects of the present invention is to provide an improved rail fastener including an anchor member fixedly secured to a crosstie and containing a longitudinal spring clip therein having its medial portion deflected downwardly by means of a removable cross pin.
  • a further object ofthe present invention is to provide an improved rail fastener including an anchor member secured to a crosstie and provided with a pair of upwardly extending sidewalls connected by a top bridge with a removable cross pin insertable between said sidewalls and bearing against the under surface of the bridge on the one hand and serving to downwardly deflect a spring clip insertable between said sidewalls beneath said pin.
  • Still another object of the present invention is to provide an improved rail fastener including an anchor member fixedly attached to the crosstie and containing a removable spring clip maintained in a downwardly deflected condition by means of a removable transversely disposed pin and a gage block insertable between said anchor member and a rail base flange and upon which one end of the spring clip bears.
  • Another object of the present invention is to provide an improved rail fastener including an anchor member having a pair of spaced apart vertical sidewalls between which is disposed an L-shaped spring clip having a rail engaging section on the one end and a vertical pivotal section on the other end directed downwardly toward the upper surface of the crosstie.

  • an anchor member 2 to inhibit the longitu dinal creeping of a rail R as disposed upon the upper surface 3 of a crosstie T.
  • the anchor member 2 must be thoroughly secured relative the upper surface 3 of the crosstie and in the case of a concrete crosstie, this is most readily achieved by forming the anchor member with an integral stem 4 during casting thereof.
  • the stem is then placed in the concrete of the tie during the casting of the crosstie.
  • the exact construction of the stem is immaterial as it may include any of various forms of projections 4, such as grooves or serrations, or it may be otherwise irregularly configured to enhance its retention within the crosstie following its casting.
  • the anchor member 2 comprises a substantially planar base 5 flushly disposed upon the upper surface 3 of the crosstie and from which the stem 4 depends. Extending upwardly from the two opposite sides of the base 5 are a pair of vertical sidewalls 6-6 the limits of which are disposed in a plane well above the base of the rail. The spaced apart sidewalls 6-6 define a channel 8 therebetween which is bounded at its top by means of a transverse bridge 9 having inclined sides l0l0 shown most clearly in FIGS. 2 and 3.
  • the two sidewalls 6 are provided with aligned openings 1 1, the upper portion of the circumference of which is contiguous with the arcuate bridge undersurface 12 such that the bottom of the bridge 9 serves as a curved bearing surface continuously extending from one side wall opening 11 to the other side wall opening 11, and the function of which will become obvious hereinafter.
  • the two sidewalls 6 are provided with aligned openings 1 1, the upper portion of the circumference of which is contiguous with the arcuate bridge undersurface 12 such that the bottom of the bridge 9 serves as a curved bearing surface continuously extending from one side wall opening 11 to the other side wall opening 11, and the function of which will become obvious hereinafter.
  • the two sidewalls 6 are provided with aligned openings 1 1, the upper portion of the circumference of which is contiguous with the arcuate bridge undersurface 12 such that the bottom of the bridge 9 serves as a curved bearing surface continuously extending from one side wall opening 11 to the other side wall opening 11, and the function of which will become obvious hereinafter.
  • included angle formed by the two bridge sides -10 is no less than 30.
  • the spring clip 1 comprising a unitary metal member preferably L-shaped to provide a vertical pivot arm or tie section 13 at one end, an intermediate central body section 14 and a rail engaging section 15 at the other end.
  • the rail fastener of the present invention is intended to be used in pairs, that is, one such assembly on opposite sides of a rail R and cooperating with the two oppositely disposed rail base flanges 16.
  • the anchor members 2 would be initially secured to the crosstie T such that the opposed inner edges 17 of each pair of spaced apart anchor members 2 would be spaced from one another a distance sufficient to accommodate rails of different weights intended to be used with the invention.
  • gage block 18 having a vertical edge flange 19 insertable between the rail base edge and the inner edge 17 of each anchor member 2 with a top arm 20 of the gage block overlying the upper surface 21 of the rail base flange 16.
  • a more positive retention of the gage block 15 may be ensured by providing a notch 22 within the inner edge 17 of the anchor member as shown most clearly in FIG. 1 whereupon any longitudinal shifting of the gage block will be precluded.
  • bearing means comprising a transversely disposed bearing groove 23 formed in the upper surface of the anchor member base 5 and into which the rounded tip 24 of the clip pivot arm section 13 is disposed.
  • bearing means comprising a transversely disposed bearing groove 23 formed in the upper surface of the anchor member base 5 and into which the rounded tip 24 of the clip pivot arm section 13 is disposed.
  • the upwardly curved tip 25 forming the distal portion of the rail section 15 of the spring clip is properly located relative the upper surface 21 of the rail flange and more specifically the upper surface of the top arm 20 of the gage block 18.
  • a close fit is provided by the proximity of the parallel lateral edges la of the clip to the parallel lateral limits of the channel 8 as defined by the anchor member side walls 6-6.
  • the cross pin 26 is inserted merely by striking its head 27' with a maul thereby driving the feed end 28 thereof through a first one of the openings 11 and while the top of the pin bears against and is guided in a straight line by the curved bridge undersurface 12, continuing to drive the pin over the top surface of the spring central body section 14 to progressively downwardly depress this area of the spring clip as the feed end 28 is driven thereover and subsequently through the second one of the openings 11.
  • a chamfer 29 formed adjacent the feed end 28 of the cross pin provides a camming action assisting in the initial deflection of the spring clip and the subsequent passage of the feed end through the second one of the openings 11. Additionally, a slight taper may be provided adjacent the chamfer to facilitate the assembly.
  • FIG. 2 of the drawings most clearly illustrates additional structure providing an insulated arrangement.
  • a tie bearing pad 30 of suitable insulating material may be provided intermediate the rail base flange and the upper section of the crosstie while at the same time a suitable insulating layer 31 may be applied as a coating to the undersurface of the gage block top arm 20 and edge flange 19 such that the rail R is totally electrically isolated from both the crosstie and the rail fastener of the present invention.
  • FIG. 4 of the drawing shows an embodiment wherein the same concept as described above is employed but wherein a longer spring clip 1' is utilized, an arrangement which has been found to provide improved holding power in certain installations.
  • the rail section 15 and pivot arm section 13 are both substantially longer than the corresponding portions of the previously described spring clip 1.
  • the cross pin 26 engages the central body section 14 substantially medially of the longitudinal upper portion of the clip, it has been found that in the embodiment of FIG. 4, an improved device is achieved by providing the pivot section 13' longer than the rail section 15'.
  • a suitable spring clip 1 may define an overall length of four inches from the contact line 15a to the vertical axis passing through the tip 24 and with the cross pin 26 deflecting the intermediate central body section at substantially the medial point of the clip, while in the embodiment illustrated in FIG. 4 a suitable spring clip 1 includes an overall length of approximately seven inches with the cross pin 26 engaging a central body section 14' at a point which is three inches from the pressure contact line 15a and thus 4 inches from the vertical axis of the tip 24.
  • a separate bearing member 32 may be imbedded or cast in situ within the crosstie T and further interlocked therewith by the inclusion of a suitable stem 33 depending therefrom.
  • the anchor member 2' deflects the spring clip 1' at a point from the rail which is greater than in the first described embodiment it is necessary to provide an inner base extension 5" in order to present the notch 22 therein at a point adjacent the edge of the rail base flange 16 so that the gage block 18 may cooperate therewith to define the specified gage.
