The bases of 60 5 of Cook and State of Illinois, have invented the COIlIleCtlg mils E E' E2 E3, and the certain new and useful Improvements in bases Of the rails F and G where they are Railway-Crossings, of which the 'following coupled with the arms of the base plate, are is a specification. omitted from these rail sections, but these The present invention relates to improvebases are Supplied by the cruciform cast- 65 i ments in railway crossings, and is designed lhg's as Shown. y

Wlth @G Tltfl SOS 0l IlOCheS aS 15 and .16

,j Each of the four joints is built upon a respectively so that, as clearly seen 1n Fig 105 base plate of cruciform shape comprising 6, the guard m11 8 may sWlIlg t0 the right the four arms 1, 2, 3, and 4C. These arms are without interference from the rail 7, and each slotted as at 4 and the usual rail heads the rail 7 may swing to the left Without are omitted from the arms, but the heads of interference from the rail S. To reinforce the sections F, Gr, E, E E2 and E3 are suband brace the joint between these crossed 110 stituted therefor, while the webs E4 of the rails I provide them with angular lugs as connecting sections and the Webs F of the 7a and 8n respectively, and the outer face of these'l lugs` is struck froma line With the` hinge bolts 10 as a center. Each of these lugs is alined with the tracky that it intersects, and the connection rails or sections E E E2 and E3 have their ends 17 rounded at the underside of their heads so that these lugs may turn doWn under the ends. At 7b and 8b the lugs 7a and 8@L are slotted so that they may fold down past the ends of the Webs E4, as indicated in Figs. 4 and 5, and thisarrangement of parts further adds to the stability of the devices.

In operation, assuming a car to be passing over the crossing from left to right in'Fig. 3, the lianges of the Wheels Will engage the guard rails 7, 7 and turn them both in'- Wardly and hold the rails in this position until the Wheels have passed through the joint, when the rails are turned back to normal position by the springs 18. The second pair of rails 7 is noW encountered by the Wheels and they are also turned inwardly, and after passage of the Wheels, are returned by their springs 13. It Will be noted that the track from left to right is continuous and smooth and the Wheels travel over a continuous surface, as the gaps are closed and filled on the track over Which the Wheels are to pass. In this manner the objectionable features of noise and Wear are avoided in the crossing of cars, and the guard rails after being opened by the car Wheels and held so until the Wheels pass, are automatically returned to normal closed position. All parts 'Copies ot this patent may be obtainedlor ofH the rail sections are closeitting, as seen in Figs. 2, 4 and 5, and the tops of the rails or rail heads form' a continuous and smooth surface for the Wheels to travel over.

What I claim is l. The combination in a rail crossing With four corner base plates and rail sections connecting them, of a pair of crossed guard rails hinged at the sides of the crossing arranged in pairs parallel With the intersecting rails and adapted to be turned down on their hinges, and means for holding the guard rails in normal upright position.

2. The combination with a cruciform shape base plate, of a pair of notched and crossed guard rails each respectively hinged to the base plate at the sides of the corner and adapted to be turned down flat, bolts passed through perforations in the rails and base plate, and springs held on said bolts to return the guard rails to normal upright position.

3. The combination with a cruciform base plate of a pair of notched and crossed guard rails separately hinged to the base plate and each formed With a projecting lug formed with a circular 'face adapted to co-act With the rail that the guard rail intersects, and means for holding the guard rails in normal position.

In testimony whereof I aiiX my signature.
