32 Claims.

This invention pertains toY railway crossings', and more particularly to crossing including metallic plate members adapted to be interlocked suitably between and adjacent track rails at a crossing.

In the present day crossings it is desirable to build up space between and adjacent rails to provideY as smooth a crossing as possible, yet at the same time it is desirable to build up the O crossing with a plurality of metallic plates which will be no forces pressing against the' crossing between the ties toi-tend to loosen the plates;

It' is therefore an object of this invention to provide a crossing includinga plurality of plates interlocked toforrn a smooth crossing and onev which is' readily applied and removed.

Another' object of the invention is to providen an improved railway crossing wherein therev is no interference With any track circuits and wherein the partsY yare arrangedV so" that there is no tendency of the same to loosen upon any' settling' action of theA road bed;

Aj further object of the invention is tov provide an improved railway crossing inexpensive'to make` and maintain', and one which fullls all requirements of manufacture and service'.

With these andv various other objects in' view, the invention may consist of certain novelifea` tures ofV construction and operation as' will be more fully described and particularly pointed out in the specification, drawings and' claims api' pended hereto.

In the drawings, which illustrate'fanA einbodi? ment of the device and wherein like reference characters are used to designate like partsv Figure 1 is a fragmentary topplan View of a` railway crossing embodying'M the invention;

Figure 2 is a sectional elevation throng-ha road-bed taken at the side of theembodiment of theinven'tion shown in Figure 1; Figure 3 is a transverse sectional elevation through the road bed illustrated in Figure. 1 takenat one end thereof;

Figure'4 is an enlarged fragmentary sectional (ci. ees-s) elevation through a crossing, the same corresponding substantially' to Figure 2, showing thev interlock of adjacent plate members;

Figure 5 is a top plan view of one of the center' plates used in the crossing Figure 6 is an end elevation of the center plate illustrated in Figure 5, the same showing the interfitting tongues;-

Figurev 7 is an end elevation of the center plate illustrated in Figure 5 taken at the opposite end from that shown in Figure 6; and

Figure 8 is a side elevation of the center plate shown in Figure 5.

In the embodiment of the invention illustrated, spaced rails l0 are mounted on successive and adjacent ties 12 extending transversely of said rails, the road bed being completed by suitable ballast,` not shown. The crossing extends toward the rails and transversely thereof, and is approached by means of approach and end platesv 14 between which are disposed approach plates 1:6 of any suitable number, depending upon the width of the crossing. The crossing is completed between the rails by means of end plates 18" shown in alignment/with the approach and end plates; and av suitable number of intermediate center plates 20.

Each approachr and end plate, as shown, is provided with a' main plate portion 22 provided with suitable anti-skid means such as the buttons 24, the' sides'of said plates adjacent the rails l0 being provided witha depending flange 26. The plates are also provided with central reinforcing ribs 28 and outer reinforcing flanges' 30 spaced from the outer edgev of the plates and reinforced by means of brackets 32,` the reinforcing flanges preferably merging into an approach. portion 34,

as shown, disposed at anv angle of approxinfiately and merging into a' flange or foot 36 adapted to receive the spikes 38v securing saidy fiange to the cross ties.

The reinforcing membersV also merge into a depending flange 40 reflanged at 42 to providev means" for receiving spike 44 for securing the other support of the plate to the? adjacentfcross ties, The flange 42 preferably does'not extend. the'entirewidth of the plate, but terminate'sshort ofthe inner and outer edges to provide clearance for'the rail mountings' 45, the member 34'andthe flange 36 being also of a size to fit on the tie and to clear the'rail mountings; The vertically eX-` tending fiange 40 is apertured at 46 to receive the interlockingtongue 48 provided on the adjacent approach plate 50. As shown, the tongue 48 is a downwardly sloping member reinforced by the soNv bracket 52 and the plate 16 is correspondingly thickened at 54 to provide a proper t for the tongue.

The plate 50 is provided with a shortened leg 56 provided with the flange 58 adapted to rest on the flange 42 but to avoid the spike 44 which secures the flange 42 to the tie. The opposite leg 60 of each approach plate corresponds to the leg and is adapted to receive the adjacent leg 56 of the adjacent plate. The leg 60 is likewise apertured to receive the bracket 48 and the plate 50 is thickened for accommodating a proper lit. The plate 50, as well as the other plates, is provided with anti-skid means as the buttons 24. The approach plates are also provided with the side and intermediate flanges 126, 128 and 130 corresponding to the

flanges

26, 28 and 30 of the end and approach plates. It is of course to be understood that the flanges of the legs are of corresponding size to the flanges of the legs of the end and approach plates to clear the rail mountings and t on the ties 12. The end plates 18 disposed between the rails also are provided with a substantially 45 approach portion Y 62 provided with ilanged portions 64 for facilitating the fastening of the end plates to the cross ties, the flanges adjacent the rails being inwardly directed from the side edges of the plates in order to clear the rail mountings. The center plates 20 are provided with legs having langes for facilitating the fastening to the rail ties.

The end plates and center plates are provided with cooperating :interlocking portions corresponding to the interlocking

portions

48 and 54 already described for the approach and end plates and approach plates, and similar reinforcing flanges are also formed. The center plates, shown particularly in Figures 5 to 8, in-

v Lelusive, are similar to plates in that they 40 are provided with a top plate portion having anti-skid buttons 24, and side and

intermediate llanges

226, 228 and 230 corresponding to

flanges

26, 28 and 30. The depending legs 256 are shorter than the legs 260, said legs being ilanged as at 242 and 342, respectively, to provide foot portions. Legs 256 are provided with tongues or brackets 48, and legs 260 are apertured as at 46 to receive adjacent tongues 48 of adjacent plates. The

u foot portions 342 are apertured at 343 to receive securing spikes and are broadened for receiving the flanges or foot portions 242 of the adjacent plates, the portions 242 being of such size and dsposition as to clear the apertures 343, as is clearly indicated in Figure 5.

In the case of the end plates and center plates, as well as the approach and end plates and approach plates, it may be stated that in general successive plates are provided with short adjacent legs adapted to be tted on the longer leg of the 'adjacent plate as particularly shown in Figure 4, which construction, with the interlocking portions, forms a strong as well as smooth crossing assembly.

The crossing, then, consists of a series of pref erably cast steel sections or plates comprising end there are provided the projecting members adapted to t into openings in adjacent plates, and at the same time there is a lower supporting ilange on adjacent legs for the shorter legs of adjacent plates. By forcing the plates together a tight joint is obtained at the point where the center plates meet the end plates. The other ends of the center plates are then spiked down to the cross tie and the remaining center plates are installed in a similar manner. The crossing is completed by the end and end approach plates which are interlocked with center plates, the end being spiked down to the cross tie, which forms a perfect interlocked crossing arrangement. In order to remove the plates for replacement of cross ties or any other reasons, the reverse operation is required.

It will thus be seen that a very smooth crossing is obtained, one which in no wise interferes with trackv circuits, and one in which any settling of the road bed will not cause loosening of the crossing plates; and it is to be understood that we do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
