Concrete railroad tie anchor structure

A concrete railroad tie and anchor structure for holding rails on a road bed comprising:

• an elongated block of reinforced concrete spanning the distance between two parallel rails;
• a base plate adapted to be disposed in a generally horizontal position on the tie;
• integral upwardly projecting shoulders rigid with said base plate at opposite sides thereof and extending away from said plate to cooperate therewith in presenting a seat for said rail;
• a first generally arcuate segment integral with each of said shoulders and extending away from the adjacent end of the base plate in the general direction of said concrete block to cooperate with the latter in presenting an opening;
• a second generally arcuate segment integral with each of said first segments and extending in an arc intersecting the arc of the first segment to present a groove along the line of juncture of the first and second segments;
• blade means integrally connected with each of said second segments and extending downwardly from the end of said second segments which is farthest removed from said base plate in a continuous uninterrupted manner;
• said blade means including a planar vertically oriented upper blade portion integral with said bridging portion, a planar vertically oriented intermediate blade portion extending below said upper blade portion and having a lateral dimension less than that of said upper blade portion, and a planar lower blade portion having a greater lateral dimension than said intermediate blade portion, said lower blade portion presenting a pair of opposed anchoring edges facing generally upwardly and outwardly on opposite sides thereof;
• a resilient pad disposed on said seat intermediate the rail and the plate;
• and
• a retaining pin disposed in each of said openings and engaging said rail for holding the rail in place on said seat,
• said pin comprising a first leg extending through said opening, an integral curvilinear portion complementally engaging said first arcuate segment, and an integral second leg disposed in said groove.
