To m7] n-imm it nmy cone- 27%.-

Be it known that I, RICHARD I citizen of the United States, resioing Lo's Angcles, in the county of Los Angeles and. State of California, have invented new and useful Improvements in liaihvay-Crossings, of which the following is a specification.

My invention relates to that portion or a railwa\ '-crossiI1g where the railsiof one track cross those of another track at an angie t ereto; and the object thereof is to provide cheap, simple, and eflicient ineans to prevent theusual. ar which occurs when the car-wheels on one track cross over the rails of the other track. I accomplish this object by the de vice described hereinand illustrated. in the accompanying drawings, by what I will term a "railroad-rail-crossing bridge, in which- Figure 1 is a plan of a portion of two tracks crossing each other at rightv angles with mybridge in place where the respective rails cross each other. Fig.2 1s a section on the line 2 2 of Fig. 1. Fig. 3 is a sectionon the perspective line 3 3 of Fig. 2. Fig. 4 is in the drawings the rails 5 and 6 one track cross the rails 7 and 8 of the other track at right angles thereto. The tread of each rail. at its point of intersection with the other rail is grooved transversely to allow for the passage through such groove of the flange of the car-wheels which travel upon the other track. In these flange-channels 10 I provide a bridge 11, which has' as many-arms 11 as there channels at such rai1-crossing,which arms project from the intersection of such channels a suflicient distance to gradually engage the flange 13 of the wheel 14 and gradually raise it .high enough so that the tread 15 of the wheel will be above the tread oi the rail when it reachesthe flange-channel fit-the crossing, thereby preventing the wheel from jarring, as it now does in the ordinary railway-crossings. v

In the top surface of my bridge. are flangegrocves '12, which keep the flange central in the bridge and prevent the flange from running of? the bridge as it crosses the flangechannei of the railroad-rail.

I prefer to make my bridge of heavy springs steel and he the body or central portion thereof raised slightly above the bottom of the rail-flange channel. The ends of the arms which aretapend rest upon the bottom of the raihilange channel, as best shown in this construction the tread'of the wheel is prevented from being injured as it passes over the flangecl1annel of the rail and all jar therefrom is likewise avoided.

'Ha :ing described 1ny.invention,.-what I claim ,a's.new, and desire to seciire by Letters Patent, is."

. A bridge for railway-rail crossings comprising av body havinga plurality of resilient tapered arms adapted to fit into the flange- .channels of the railway-rail crossing at their intersection,'said body being raised slightly above the bottom of the flange-channels, and the ends of the arms resting upon the bottom E the 'flange channels and having central grooves in the top of the arms and body.

In witness that I claim the foregoing I have hereunto subscribed my name this 7th day of September, 1905.

RICHARD WALTON.
