Specification of Letters latenth Application filed October 2, 1916. Serial No. 123,309.
To all whom it may concern:
Be it known that I, Mosns A. VVoonnniocn,
a citizen of the United States, residing at features of construction and combinations of parts which will. be hereinafter described and pointed out in the claims.
In the accompanying drawing Figure 1 is a view in top plan of the invention;
Fig. 4 is a perspective view of the central plate slightly modified.
A, represents the ties, and B the two rails, which may be fastened to the ties in the usual manner.
Located between the rails B, and parallel therewith are a pair of wooden bars 1. The bars are of suflicient height to support a plate 2, made preferably of heavy slab iron or malleable iron, in the proper plane with the upper surface of the ball or tread (if the rails B.
The plate 2 is preferably made of such a length as to accommodate the traiiic, but several lengths may be employed when found desirable. The plate 2 and bars 1, are fastened to the ties A, by means of bolts, screws or spikes 3 which pass through the plate, and bars. into the ties for rigidly maintaining the plate and bars in position. The longitudinal edges of the plate 2 are bent downwardly and then upwardly so that the edges lie beneath the ball or tread of the rails, forming a trough or groove 10' along each side of the plate, so that there is no interference with the travel of trafiic over the rails, and insures against the packing of dirt and gravel between the plate and rails, I
and any water willfiow oil, so that the plate is. practically self-cleaning against the lodging of sleet and snow.
Inclined plates 4 are located at the ends I, of the-bars 1, and are fastened to the bars and ties by means of bolts or screws 5. The plates form a means to" prevent anything hanging from the car or trucks engaging the plate 2 and causing its disarrangement.
Located along the. outer surface of each rail B, and parallel therewith are wooden bars 6, to which are connected inclined "plates 7 by means of bolts or screws 8,
which pass through the plates and bars and into the ties A for fastening them in position. The outer or lower edges of the plates 7 are. connected to the ties by bolts, spikes or screws 9.
The plates 2 and 7 are each provided with angle iron braces '12 and 11', respectively, which are connected to lower surfaces thereof by rivets, and extend transversely thereof.
It may be advisable in some instances to omit the grooves or troughs 10 from the central plate 2, and simply allow the edges of the plate to extend down between the rails i clined plates connected to the bars located along the outer surfaces of the rails, and means passing through the plates, and bar and into the ties for fastening them in place.
2. A railroad crossing, comprising ties and rails, bars located between and along the outer surfaces of the rails and extend- Patented June'12, 1917.
ing parallel to the rails, a plate supported on the bars between the rails, the edges of the plate being bent soithat they are 10- eated beneath the tread of the rail, inclined plates engaging the ends of said bars and resting 'on the ties'for-forming a protection for the ends of the plate, inclined plates supported on the bars located on the ties along the outer surface of the rails, and means passing through said plates and bars 10 and into the ties for fastening the bars and plates in positipn.
