- RAILWAY CROSSING'.

Original No. 1,551,165, dated August 25, 1925, Serial No. 728,282, leduly 26, 1924. Application for 4 reissue filed April 21, 1927. Serial No. 185,866. f,

This invention relates to improvements in railway crossings, and has for yits object to provide a Structure utilized to provide a continuation `of a roadway across a railway track.

In my co-pending application, Serial No. 674,638, iiled November' k14, 1923, Patent No. 1,551,164, grantedvAugust 25, 1925, I have illustrated a somewhat similar structure as applied to an existing trackway. In the herein describedinvention, I have illustrated` a modified structure utilized in conjunction with a concrete roadway.

The object of the present invention is` to provide andfsecurea quickly applied means to locky the crossing plates to the track rails and to insulate the same therefrom to prevent short-circuiting of current for signalling or the like. l

` These and other objects will be more fully described in thek following specifications and `shown in the accompanying drawing, in

which- Y Figure 1 is a plan view of one embodiment ofmy invention.;

Figure 2 is a vertical transverse section along the line A-A of Figure 1.; j y

Figure 3 is a vertical section drawnto an enlarged scale of a portion of the structure showing the locking means;

Figure 4 is aside elevation `of a pair of coacting wedge blocks.

Like numerals refer to like elements i throughout the drawings, in which 10 designates generally the track rails having the usual head portions 1,0, web portions 10d, and transverse base fianges 1()b and 10. yThe rails are supported in the usual manner yupon ties or sleepers 12. I have illustrated a portion of the concrete roadway at either side yof the track which, in the embodiment shown, is a singlel track line, although my"invention is readilyapplicable to double or other track systems as will be obvious.

At the 'outer side of each rail is provided `an approach plate50, each plate having anr edge et inset in the concrete C. Depending webs 50b are supported between the transverse ties 12, while a face flange 50c projects slightly forward ,from the approach plate to partially `underlie the rail head 10?, being supported on. the flange l()h therebeneath.

The `interniedgiate plates are designated by the numeral 60, andextend between and aresupported upon the rail flanges as shown in.

Figure 2, for example. In the .afQITm shown,

sulating material are interposed between the j flanged bottom portion GOn and the rail flanges 1()C upon .which they are supported, thus preventing short-circuitingoi' currents ior signalling or the like. Instead of utilizing a single locking block, `as in the above described form, I utilize pairs of co-acting wedge blocks 63 and 64E, fitting in the grooves between the rib 60 and bottom portion 60h, and having inclined contact surfaces as ment of one block with respect to its comple;-l mental bl'ock will increase the locking of the intermediate plate tothe rail, as will be ob- `shown in Figurel whereby relative displace.- i

viousi The nail or the like, indicated by the numeral 65, is driven into. each lower wedge block 64.-` as shown -in Figure L after position.- ing o the blocks `.to prevent relativejdisplacement thereof, which would release and per? mit vertical displacement of the plates. The

wedges being in pairs are quickly insertable where desired, no `wedging resistance being present until the upper section is moved relative to the bottom section.

Transverse ribs or stiilening flanges (i0d are .castor formed integrally with the plate 60 to increase the strength and rigidity. thereof.

At its endsythe intermediate crossing is provided with the sloping. aprons 60e andthe approach with aprons 50d extending down-` wardly ,and y.outwardly to adjacent the roadbed. This prevents engagement of the struc.- ture by chains, hose, or the like dangling from passing-trains.

It will be obvious that by the structure as desired.

' `above described and shown inthe drawing, j

It will be obvious that my invention is susceptible of modification, and I do not wish to be restricted to the form shown and described, except as defined in the appended claims.
