Abstract
A track supporting railway tie collar includes an upper receptacle for slidably and loosely receiving an end portion of a cross tie and a lower enlarged portion supported in the ballast beneath the track structure. The collar serves to transfer the weight of the train directly to the ground, rather than through the tie, thereby greatly prolonging the life of the tie and minimizing track maintenance.
Claims11
A railway tie collar for supporting a rail over spaced ties and ballast, said tie collar comprising a unitary rigid structure having an upper portion and lower portion, said upper portion comprising an upper wall for supporting a rail and a pair of side walls extending between said top wall and said lower portion, and a cavity through said upper portion between said top and side walls, said cavity being dimensioned to loosely and slidably receive each tie near each end portion thereof, whereby vertical forces on the tie collar are substantially borne by the tie collar, thereby minimizing wear and stress on said tie, said lower portion being flared outwardly from the upper portion and being of sufficient length to engage within said ballast.
A railway track arrangement for supporting rails over spaced ties and ballast, said arrangement comprising a tie and a tie collar at each end of said tie, each said tie collar having an upper portion and a lower portion in a unitary rigid structure, said upper portion having a top surface for supporting a rail, a receptacle through said upper portion, each end of a tie extending through said receptacles and having vertical clearance therewith, means for restraining horizontal movement between said tie and said tie collar, said lower portion diverging outwardly from said upper portion and engaging within said ballast, said vertical clearance permitting vertical forces exerted on said arrangement to be borne substantially by said tie collar and not the tie.
