EDMOND F. BOSDEVEX, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR 0F ONE-THIRD TO NETTI'E ARMSTRONG, 0F PHILADELPHIA, PENNSYLVANIA.

RAILWAY-GnossrNG.

Specification of Letters Patent.

Application filed March 19, 1914.

Patented Julie 16, 1914. Serial No. 825,738.

T 0 all whom it may concern Be it known that I, EDMOND F. Bosnnvnx, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Railway-Crossing, of which the following is a specification.

My invention consists of railway rails provided at the intersection of crossing tracks with novel means for preventing the jar or noise of car wheels at said intersections and the battering and injuring of the edges of the rails thereat. To this end, I employ a bed plate formed of a circular head, which is `adapted to occupy the space at the crossing and a bolt pendant from said head adapted to enter an opening in the base of the crossing at said space, said head being adapted to have the flanges of the wheel ride thereon so as to elevate the treads of the latter and remove them from direct contact with the edges 'of the rails at the intersections.

It consists also in forming a recess in the base of the grooves of the crossing rails, the

same being adapted to receive the head of the bed plate, so as to seat it firmly in position and prevent shifting of said head when it is engaged by the flange of a car Wheel. It consists also in adapting the head of the bed plate to be seated firmly within the ends of the rails at the crossing thereof.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described.

Figure l represents a top or plan view of a railroad crossing with a bed plate embodying my invention applied thereto. Fig. 2 represents a top view of a portion of a crossing on an enlarged scale, as illustrative of my invention. Figs. 3 and 4. represent vertical sections thereof. Fig. 5 represents a perspective view of the bed plate employed.

Similar numerals of reference indicate corresponding parts in the figures. K

Referring to the drawings :-l designates a well known form of a railway crossing. In the bases of the grooves 2 in the rails at the intersections of the crossing rails are the circular recesses 3 which are below said grooves so as to form the circular' shoulders il. In said bases centered in said recesses are the vertically-extending openings 5. The four corners of the rails at the intersections thereof are formed with chainfers 6 which taper from the tops of the rails downwardly to the shoulders l so that the spaces in the intersections between said chamfers are comparatively conical with the widest diameters being above.

7 designates bed plates for the intersections of the crossing rails, each of the same being formed of a circular head 8, and a stem or bolt 9, depending therefrom, it being noticed that said bolt or stem occupies an opening 5, and said head is seated in a recess 3, it being seen that when the bed plates are assembled position, the upper surfaces of said head 8 are above the bases of the grooves 2, whereby when a flange of a car wheel reaches said heads it rides thereon and lifts thetreads of the wheels above the heads of the rails whereby said treads do not strike said heads at the rail crossings, thus avoiding the noise and the battering and injuring of the ends of the rails heretofore occasioned by the car wheels striking the ends in passing the crossings, as well known. After the flanges clear the heads and renter the grooves 2, the wheels run on the rails as usual.

Attention is drawn to the fact that in locating the Ibed plates, the heads thereof are placed within the spaces between the chamfers (5 of the ends of the rails and snugly occupy the same, and the stems or bolts 9 are inserted in the openings 5. plates are driven forcibly downwardly by blows imparted to the heads thereof, whereby the sides of the heads wedge downwardly with the chamfers tightening therewith in their descent, and when to full extent, they enter the recesses 3, surrounded by the shoulders -ZL thereof, whereby the plates are controlled laterally by and interlocked with the rails at the intersections thereof, and prevented from shifting or creeping, and as the l weight of the cars are superimposed on said heads as the flanges of the wheels ride over them, the plates are self tightening in their nature, and so prevented from being abstracted or removed excepting by superior force applied by prying under the heads which is required when the plates wear-out and need renewal, it being seen also that as there is frictional engagement of the peripheries or sides of the head with the ends of Then the the rails at the crossing there is increasing tightening of the heads on said ends, as the bed plates are driven down by the primary superior force, and avoid also the employment of screw belts on the heads and threaded openings in the crossing, and nuts on the lower terminals of the bolts below the crossings and subsequent Weight of the cars.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

l. In a railway crossing an elevating bed plate adapted to occupy the space at the crossing composed of a head of circular form, and a bolt depending therefrom, the periphery of `said head being adapted to engage frictionally the ends of the rails at said crossing and tighten thereagainst.

2. A railway crossing having in the base of the rails at the space of the crossing below the ange-receiving grooves of the latter a recess, and an opening extending downwardly from said recess and a bed plate formed of a circular head, and a bolt depending therefrom, the periphery of said head being adapted to engage frictionally the ends of the rails at said crossing and tighten thereagainst.

8. A railway crossing having in the base of the rails at the space of the crossing a ed to fit within the ends of the rails and fric- I tionally engage with said ends and tighten thereagainst and said bolt to enter said opening.

4. A railway crossing having the ends of the rails at the crossing formed with downwardly extending chamfers, a recess in the space at the base of the crossing below the flange-receiving grooves of the latter, an opening extending downwardly from said recess, and a wheel-elevating bed plate come posed of a circular head, and a bolt depending therefrom, the side of said head being adapted to lit within said chamfers, the body of said head being adapted to be seated on said recess, and said bolt to enter said I opening.
