Patent

CA 2387824

A modular tongue switch assembly comprises a tongue pivotally connected to a slide surface, held down by a pivot retainer. The slide surface consists of slide plate sections removably attached to corresponding bed plate sections, which are in turn welded onto a base plate. Floating brace blocks hold a non-integral stock rail in place on the base plate. When the tongue moves, a horizontal lever arm actuates an inner box assembly housed within an outer box and containing the conductor rail, allowing the passing train to maintain contact with the conductor rail, if necessary. A novel rodding and lever arrangement is used.
