Ifatented Sept. 25, 1906.

Application filed January 26.1906- Serial No. 298,050.

To all whom it may concern/.1

Be it known that I, EDWARD J. FOGARTY, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented new and useful Improvements in Railroad Crossovers, of which the following is a specification.

This invention relates to an improved pav ing for railway-crossings where a street orroad intersects a railroad-track; and the object generally is to provide a substantial pavement which will be continuous and flush with the top of'the rails to permit pedestrians pnd vehicles to cross the track on a level surace.

A further object is to provide a construction and arrangement that will relieve the paving-blocks from jar or vibration incident to the traffic on the track by the railway-cars, and thus prevent displacement of the pavingblocks or their foundation. r

These and other objects will be better understood by reference to the following description and to the accompanying drawings, in which- Figure 1 is a perspective view of a paving for a railway street-crossing constructed in accordance with my invention, with the paving-blocks and their foundations shown in transverse section. view of one of the paving-blocks employed, and Fig. 3 is a perspective view of another paving-block.

Making renewed reference to the drawings, 1 designates the ties, which are laid in the road-bed as usual, and 2 designates the rails mounted on .the ties, being-secured thereto by any suitable track-fastening. Mounted on the ties on each side of the rail are bed- pieces 3 and 4. These bed-pieces consist of bars of cast-iron that extend parallel with the rails and have their inner sides sha ed to conform to the web and base of the rai there being a flan e 5 at the bottom that projects beyond the arse-flange of the rail and rests upon the ties,"as shown; These bed-pieces also have upward extensions 6, that flare slightly outwardly from the rail and surround the sides of the tread portion thereof, with theirup er surfaces -fiush with the tread of the rail, tffus providing a chair for the rails, and preferably the extension 6 of the inner bed-pieces 4 is separated far enough away the rail to provide a space or groove for the flange of the wheels of the rolling-stock, whereby the said extensions serve as guard- Fig. 2 is a perspective upper surface above the ties,

from the tread of rails. The outer sides of these bed-pieces are concaved transversely, the concavity extending from the top to a shoulder 7 above the base of the flange 5, the said shoulder forming a seat for the lower inner edge of the paving-blocks-adjacent to the bed-pieces.

' In Fig. 2 one of the paving-blocks 8 is shown as consisting of substantially a rectangular block with one side convexed, as at 9, and the opposite side provided with a lon gitudinal groove 10. The convexed face 9 is adapted to engage with the concaved face of the bed-piece, as shown in Fig. 1, and the groove 10 is adapted to receive a tongue 11 of an adjacent block 12, whose opposite face is provided with a similar longitudinal groove 13 to receive the tongue of another block. I

refer to have the first two or three rows of locks adjacent to the bed-pieces provided with these tongues and grooves; but as this is an expensive construction the blocks may be of the plain type with straight flat sides, inasmuch as any jar or vibration incident to the traffic on the rails will not be communicated to the blocks near the center of the track or at any great distance from the rails, and therefore the blocks are not liable to be dislodged from their foundation; but in some instances it may be advisable to employ the tongue-and-grooved blocks throughout the pavement, while in other instances the tongue-and-grooved blocks may be entirely dispensed with.

The paving-blocks are preferably laid upon a foundation 14 of cement, which is filled in between the-ties and over the same, with its so that the foundation for the paving-blocks is entirely =independent of the foundation for the ties and rails and bed-pieces, and thus the strains and vibrations upon the rails and bed-pieces are not communicated to the paving-blocks, but to the ties, as usual.

From the description thus far given it will be seen that each rail is supported and partially inclosed by a chair constituted by the bed-pieces 3and 4, which not only supports the rails, but also, receives the strain and vibration incident to the trafiic thereon, and, further, that such strains are communicate to the ties and not to the cement foundation for the paving-blodks or to the latter. Fur thermore, any lateral vibrations of the bedpieces incident to vehicles crossing the track or the rolling-stock upon the rails will not tend to dislodge the paving-blocks adjacent .to' said bed-pieces because of the contiguous paving-blocks aid upon said foundation berails, of bed-pieces mounted on the ties and &

curved faces of the bed-pieces and the blocks 8 adjacent thereto, the elimination of such dislodgment being augmented by the grooveand-tongue connection of the blocks, though, as before stated, these may be omitted without departing from the principle of. m invention. It will also be seen that the b ocks engaging the rails on opposite sides thereof, a bed or foundation laid between and over the ties with its up or surface above the ties, and

tween the bed-pieces.

2. The combination with the ties and rails, of bed-pieces mounted on the ties and engagingthe rails on opposite sides thereof, and having their outer faces concaved, a foundation laid between and over the ties with its upper surface above the ties, paving-blocks 'laid upon said foundation between the bedfiieces, the paving-blocks adjacent to the ed-pieces having their contiguous faces convexed and fitted into the concavity of the bed-pieces, substantially as described.

3. The combination with the ties and the rails, of bed-pieces mounted on the ties and engaging the rails on opposite sides thereof and having their outer faces concaved and also provided witha'basaflange which rests upon the ties and provides a shoulder at the bottom 'of thefconcaved face, paving-blocks laid between the bed-pieces, the pavingblocks adjacent to the bed-pieces having convexed faces engaged with the concaved face of the bed-piece and resting on the shoulv der above the flange of the bed-piece, substantially as described.

4. The combination with the ties and the I rails mounted thereon, of bed-pieces mounted on each side of the rail and having baseflanges engaged with the ties, the inner bed pieces having upward extensions spaced from the tread of the rail to'constituteguardrails, a bed or foundationlaid between and over the ties with its upper surface above the ties and flush with the base-flanges of the bed-pieces, pavingblocks mounted upon said foundations and having tongue-andgrooved connections with each other, the

paving-blocks contiguous to the bed-pieces partially resting upon the base-flanges thereof, substantially as described.

5. The combination with the ties and rails,

of bed-pieces mounted on theties and engaging the rails on opposite sides thereof, pavingblocks interlocking with said bed-pieces, and

a bed or foundation to support said pavingblocks.

In testimony whereof I affix my signature in presence of two subscribing witnesses.
