Abstract
Abstract A railroad crossing construction. The construction includes the conventional rails and ties. In addition there are provided a plurality of flat traffic plates which may be steel or other appropriate material. Each plate is positioned substantially horizontally so as to provide a flat surface for automobile traffic. Crosswise of the rails in one embodiment there are four main plates and two auxiliary plates. Each of the main plates has a downwardly extending flange on the sides of the plates which are parallel to the rails. Two of the main plates extend inwardly from each associated rail and their downwardly extending inner flanges rest on associated ties at approximately the central portion of the tie. The said inner flanges are secured to each other but are insulated from each other against the passage of electricity. Each of these plates contacts one of the rails at the adjacent end and rests on the flanges of the rail. On the opposite side of each rail is a similar plate which extends outwardly and has its downwardly extending flange secured to the outer end of the associated tie. Pivoted to each of these outwardly extending plates is a hinged plate which normally rests upon a fixed support adjacent the sides of the right of way. Should the rails, ties and ballast be forced downward by the weight of the train, truck or other vehicle passing over the crossing or should the crossing settle by reason of time or weather, the hinged outer plates pivot to accommodate for the movement of the rails and ties.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
226 words
A railroad crossing construction comprising: a plurality of railroad ties; a pair of rails secured to said ties; a main traffic plate for each rail, such plate contacting one of said rails on one side of the rail and resting on the flange of said rail and extending away from such rail in a direction toward the other rail so that there is an inwardly extending main plate; an outwardly extending support for each rail; an outwardly extending auxiliary hinged plate pivotally connected to a portion of each of the outwardly extending supports; and roadway supports for the outer ends of said outwardly extending auxiliary plates in which each outwardly extending support is an outwardly extending main traffic plate; in which there is also provided means for securing the outer portion of each of said outwardly extending main traffic plates to an outer portion of one of the associated ties; in which each of the main traffic plates is formed with a downwardly extending flange at each end; in which the two inner flanges of the two inwardly extending plates are separated from each other by a spacing strip which is not a conductor of electricity; and in which the flanges at the outer ends of the outwardly extending main traffic plates are secured to the outer end of the associated tie by a railroad spike.
Claim 2
Dependent Claim
226 words
A railroad crossing construction comprising: a plurality of railroad ties; a pair of rails secured to said ties; a main traffic plate for each rail, such plate contacting one of said rails on one side of the rail and resting on the flange of said rail and extending away from such rail in a direction toward the other rail so that there is an inwardly extending main plate; an outwardly extending support for each rail; an outwardly extending auxiliary hinged plate pivotally connected to a portion of each of the outwardly extending supports; and roadway supports for the outer ends of said outwardly extending auxiliary plates in which each outwardly extending support is an outwardly extending main traffic plate; in which there is also provided means for securing the outer portion of each of said outwardly extending main traffic plates to an outer portion of one of the associated ties; in which each of the main traffic plates is formed with a downwardly extending flange at each end; in which the two inner flanges of the two inwardly extending plates are separated from each other by a spacing strip which is not a conductor of electricity; and in which the flanges at the outer ends of the outwardly extending main traffic plates are secured to the outer end of the associated tie by a railroad spike.
Claim 3
Dependent Claim
161 words
A railroad crossing construction comprising: a plurality of railroad ties; a pair of rails secured to said ties; a plurality of pairs of main plates for each such rail, each such plate contacting its associated rail on the side of said rail opposite to the other associated plate and each such plate extending away from said rail in a direction opposite to the other associated plate so that there is for each rail a plurality of inwardly extending main plates and a plurality of outwardly extending main plates; means for securing the inwardly extending plates to each other adjacent to the center of the associated ties; means for securing the outwardly extending portion of each of said main outwardly extending plates to an outer portion of the associated ties; a pair of outwardly extending hinged auxiliary plates pivotally connected to an outer portion of each of the outwardly extending plates; and roadway supports for the outer ends of said auxiliary plates.
Claim 4
Dependent Claim
161 words
A railroad crossing construction comprising: a plurality of railroad ties; a pair of rails secured to said ties; a plurality of pairs of main plates for each such rail, each such plate contacting its associated rail on the side of said rail opposite to the other associated plate and each such plate extending away from said rail in a direction opposite to the other associated plate so that there is for each rail a plurality of inwardly extending main plates and a plurality of outwardly extending main plates; means for securing the inwardly extending plates to each other adjacent to the center of the associated ties; means for securing the outwardly extending portion of each of said main outwardly extending plates to an outer portion of the associated ties; a pair of outwardly extending hinged auxiliary plates pivotally connected to an outer portion of each of the outwardly extending plates; and roadway supports for the outer ends of said auxiliary plates.
Claim 5
Dependent Claim
30 words
The structure of claim 2, in which the ties are supported by the earth and by ballast but are free to rise and fall with passage of engines and cars.
Claim 6
Dependent Claim
30 words
The structure of claim 3, in which the outer ends of the outwardly extending main plates, as well as each of the rails are secured to the ties by spikes.
Claim 7
Dependent Claim
23 words
The structure of claim 4, in which the outer ends of the auxiliary hinged plates are supported by supports associated with the highway.
Claim 8
Dependent Claim
35 words
The structure of claim 2, in which the surface of the crossing and track, including the ties, rails, and plates may move up and down if the earth or the ballast is raised or settles.
Claim 9
Dependent Claim
24 words
The structure of claim 2, in which each of the main plates is provided at each of its ends with a downwardly extending flange.
Claim 10
Dependent Claim
251 words
A railroad crossing comprising: a plurality of railroad ties; a pair of rails secured to said ties; a plurality of pairs of main plates for each such rail, each such plate contacting its associated rail on the side of said rail opposite to the other associated plate and each such plate extending away from said rail in a direction opposite To the other associated plate so that there is for each rail a plurality of inwardly extending main plates and a plurality of outwardly extending main plates; means for securing the inwardly extending plates to each other adjacent to the center of the associated ties; means for securing the outwardly extending portion of each of said main outwardly extending plates to an outer portion of the associated ties; a pair of outwardly extending hinged auxiliary plates pivotally connected to an outer portion of each of the outwardly extending plates; and roadway supports for the outer ends of said auxiliary plates; in which each of the main plates is provided at each of its ends with a downwardly extending flange; in which each rail is clamped between the downwardly extending flanges of the two main plates associated therewith and in which the flanges at the inner end of the two inwardly extending plates are secured to each other adjacent the center of the tie by bolts extending through the downwardly extending flanges of said inwardly extending plates and through a resilient packing interposed between said flanges of said inwardly extending main plates.
Claim 11
