Abstract
A model railroad turnout assembly includes a roadbed element having an entry track thereon. The entry track includes a pair of spaced apart entry rails. Plural, branching discharge tracks are mounted on the roadbed element, each discharge track including a pair of spaced apart discharge rails. The adjacent rails of the discharge track terminate with ends intermediate the other rails of the discharge tracks. A switch element is provided and has a pair of blades at one end thereof. A frog extends from the discharge track ends over the switch. The frog is shiftable, with the switch element, such that the frog contacts an element blade to provide a continuous rail segment between a selected entry track rail and a selected discharge track rail.
Claims17
A model railroad turnout comprising:
- a roadbed element;
- an infeed track having a pair of spaced apart infeed rails mounted on said roadbed element;
- plural outfeed tracks mounted on said roadbed element, each track having a pair of spaced apart outfeed rails, wherein one rail of each pair of the outfeed track is continuous with an infeed rail, and an extension of the other rail of each outfeed pair intersect one another at a point intermediate said infeed rails;
- an elongate blade element for directing a model train traveling from the infeed track onto a related outfeed track, said blade element including a pair of spaced apart rails having rail points at one end of the blade element arranged between the rails of the infeed tracks and laterally shiftable to provide contact between only one point and only one of said infeed rails, the blade element rails converging towards one another at the other end of the blade element, said blade element and the other rail of each outfeed pair defining a gap therebetween each of said spaced apart rails of said blade element being a single continuous rail extending from said one end to said other end of said blade element;
- an elongate frog pivotably mounted on said roadbed element at one end of said frog, said frog extending over said blade element and being pivotably mounted thereto, connection means for directly connecting said frog to said blade element, said frog being constructed and arranged to pivot with lateral movement of said blade element to close said gap between a selected blade element rail and a selected outfeed rail.

In a model railroad turnout assembly for selectively directing a model train to one of plural track pairs, an improved switching mechanism comprising:
- a roadbed element;
- an entry track including a pair of spaced apart entry rails;
- plural, branching discharge tracks, each including a pair of spaced apart discharge rails, the adjacent rails of the discharge tracks terminating with ends intermediate the other rails of the discharge tracks, said adjacent rails extending along lines which intersect at a intersection point between said entry rails beyond the ends of said adjacent rails;
- a switch element having a pair of blades spaced apart a lesser distance than said entry rails, said blades having points at one end of the switch element, which points are alternately laterally shiftable with said switch element into a contacting relationship with one only of said rails of said entry track, the other end of said switch element being located adjacent said discharge track ends each of said blades being a single continuous rail extending from said one end to said other end of the switch element;
- and
- a frog extending from said discharge track ends into said switch element, which is shiftable with said switch element such that said frog contacts a blade to provide a continuous rail segment between a selected entry track rail and a selected discharge track rail.

In a model railroad turnout assembly for selectively directing a model train to one of plural track pairs, an improved switching mechanism comprising:
- an entry track including a pair of spaced apart entry rails;
- plural, branching discharge tracks, each including a pair of spaced apart discharge rails, the adjacent rails of the discharge tracks having ends intermediate the other rails of the discharge tracks, said adjacent rails extending along lines which intersect at a point between said entry rails beyond the ends of said adjacent rails;
- a switch element having a pair of blades spaced apart a lesser distance than said entry rails, said blades having points at one end of the switch element which points are shiftable with said switch element into a contacting relationship with one only of said rails of said entry track, the other end of said switch element being located adjacent said discharge track ends and including a web having a connecting bore extending therethrough and a notch located therein at the other end of said switch element, said switch element being yieldingly biased to a datum position each of said blades being a single continuous rail extending from one end to the other end of the switch element;
- a roadbed element carrying said entry track, said discharge tracks and said switch element thereon, and having a bore extending therethrough underlying said notch in said switch element;
- and
- a generally triangular shaped frog, extending between said discharge track ends and said point of intersection, which is shiftable by said switch element in the same lateral direction of movement as the switch element with the apex of the triangular shape contacting a selected blade to provide a continuous rail segment between a selected entry track rail and a selected discharge track rail, and which includes a pivot pin located on the underside thereof at one end thereof, said pivot pin extending downwardly through said switch element notch and said bore in said roadbed element and a connecting pin located on the underside of said frog adjacent said pivot pin, said connecting pin extending downwardly through said connecting bore in said switch element.
