Abstract

A switch point roller assist apparatus includes an elongated main support structure on which is movably mounted a rail securement clamp for releasably adjustably connecting the main support structure to a railroad rail. An elongated tie bar is adjustably mounted on the main support structure generally perpendicular to the main support structure. A roller support cage is pivotally adjustably mounted on the main support structure, the roller support cage supporting at least one roller rotatably mounted thereon, each roller mounted generally perpendicular to the main support structure. The tie bar is adjustably mounted to the main support structure such that the position of the tie bar is vertically adjustable relative to the main support structure. Finally, the roller support cage is adjustably mounted on the main support structure such that the position of the rollers is vertically adjustable relative to the main support structure.

Dependent claims

A switch point roller assist apparatus for attachment to a railroad rail at a switching location comprising;

an elongated main support structure having a center longitudinal axis and inner and outer ends;
rail securement means mounted on said main support structure adjacent said outer end for releasably connecting said main support structure to a railroad rail;
an elongated tie bar adjustably mounted on said main support structure adjacent said inner end generally perpendicular to said center longitudinal axis of said main support structure;
roller support means adjustably mounted on said main support structure;
at least one roller means having a center rotational axis, said roller means rotatably mounted on said roller support means such that said center rotational axis is generally perpendicular to said center longitudinal axis of said main support structure;
said tie bar adjustably mounted on said main support structure such that the position of said tie bar is vertically adjustable relative to said main support structure;
and
said roller support means adjustably mounted on said main support structure such that the position of said at least one roller means is vertically adjustable relative to said main support structure such that said roller may be fixed in multiple operative positions.
