Abstract
An insert for use in a level railway crossing includes an elongated high molecular weight body defined by a generally trapezoidal head with one planar vertical side edge, a shoulder extending outwardly and downwardly from the other side edge of the head for bearing against the bottom of one side of the head of a rail, a bottom portion for extending downwardly into engagement with the top surface of the base of the rail at the junction between such top surface and the vertical web of the rail, and circular cross section seals in longitudinally extending rectangular grooves in the one side edge of the head and in the inclined top surface of the shoulder for sealing with an adjacent plank and with the rail. The insert restricts the entry of the water and other foreign matter into the area of the bottom of the rails.

A railway crossing structure for use in a railway crossing of the type defined by center planks between the rails and outside planks on the outer sides of the rails and the rails being retained in place by rail clips, said structure comprising:
- (a) first elongated body means for insertion between a plank and one side of a rail,
- (b) second elongated body means for insertion between another plank and the other side of the rail,
- (c) each of said body means including a head portion having one straight side edge for engaging one side edge of a plank and a shoulder extending outwardly from the other side edge of said head portion for insertion beneath the head of a rail,
- (d) said head portion of said first elongated body means extending from a top edge of the rail to a top edge of the plank when inserted between the rail and the side edge of the plank,
- (e) said head portion of said second elongated body means having a portion for providing a recess below the top edge of the rail when inserted between the rail and the side edge of the other plank,
- (f) both first and second elongated body means having an inclined bottom portion extending downwardly from said head portion to a foot portion for resting on an inner top edge of a bottom flange of the rail;
- and,
- (g) whereby, said head portions provide a cover over the rail clips and provide an open space around the rail clips permitting the rail clips to flex when said first and second elongated body means are inserted.
A railway crossing insert for use in a railway crossing structure of the type defined by center planks between the rails and, optionally outside planks on the outer sides of the rails, said insert comprising:
- (a) elongated body means for use between each plank and one side of a rail,
- (b) said body means including a head portion having one straight side edge for engaging one side edge of a plank or roadway,
- (c) a shoulder extending outwardly from the other side edge of said head portion for insertion beneath the head of a rail,
- (d) an inclined bottom portion extending downwardly from said head portion for resting against an inner top edge of a rail bottom,
- (e) first sealing means for providing a seal between said one side edge of said head portion and an adjacent plank or roadway,
- (f) second sealing means for providing a seal between said shoulder and the head of the rail;
- and,
- (g) mortise means in said one side edge of said head portion for connecting tenoned strip means to said body means to widen said head portion.
A railway level crossing structure comprising:
- (a) elongated center plank means for insertion between the rail;
- and,
- (b) insert means,
- (c) said insert means including elongated body means for use between each plank and one side of a rail,
- (d) said body means including a head portion having one straight side edge for engaging one side of a plank or roadway;
- (e) a shoulder extending outwardly from the other side edge of said head portion for insertion beneath the head of a rail;
- (f) an inclined bottom portion extending downwardly from said head portion for resting against an inner top edge of a rail bottom;
- (g) first sealing means for providing a seal between said one side edge of said head portion and an adjacent plank or roadway;
- (h) second sealing means for providing a seal between said shoulder and the head of a rail,
- (i) longitudinally extending first groove means in one side edge of said head portion for receiving said first seal means;
- and,
- (j) second groove means in said shoulder for receiving said second seal means.
A railway crossing insert for use in a railway crossing structure of the type defined by center planks between the rails and, optionally outside planks on the outer sides of the rails, said insert comprising:
- (a) elongated body means for use between each plank and one side of a rail,
- (b) said body means including a head portion having one straight side edge for engaging one side edge of a plank or roadway,
- (c) a shoulder extending outwardly from the other side edge of said head portion for insertion beneath the head of a rail;
- (d) an inclined bottom portion extending downwardly from said head portion for resting against an inner top edge of a rail bottom;
- (e) first sealing means for providing a seal between said one side edge of said head portion and an adjacent plank or roadway;
- (f) second sealing means for providing a seal between said shoulder and the head of the rail;
- (g) a longitudinally extending first groove means in said one side edge of said head portion for receiving said first seal means;
- and,
- (h) second groove means in said shoulder for receiving said second seal means.
A railway crossing structure comprising:
- (a) a pair of parallel rails, each having a bottom flange and a rail head,
- (b) an elongated center plank means having first and second sides inserted between said pair of parallel rails, defining a horizontal plane therewith,
- (c) insert means for each of said rails including elongated body means inserted between said center plank means and one side of its respective rail,
- (d) track plate means extending horizontally beneath a bottom flange of each of rails and supporting its rail,
- (e) each of said track plate means extending outwardly in a horizontal plane from the bottom flange of its respective rail,
- (f) rail clips attached to each said track plate means and engaging its respective bottom flange,
- (g) one of said body means including a head portion having a side edge for engaging said first side edge of the plank means,
- (h) the other of said body means including a head portion having a side edge for engaging said second edge of said plank means,
- (i) each of said body means including a shoulder extending outwardly from the other side edge of said head portion and inserted beneath each of said rail heads,
- (j) said body means abutting said bottom flange and said center plank means;
- and,
- (k) said body means, said bottom flange, said center plank means and said track plate means forming a chamber around each of said rail clips.
