which may' be used in connection with the railway ties and trac-k rails, said plates being of such proportion that they may be prepared in stock ready for use` and may be conveniently mounted between the track rails to provide a complete, permanent crossing at a less expense ol" time than ordinary.

The invention broadly includes the use of comparatively thin bearing-plates having flanges or wings projecting downwardly .frein their longitudinal edges to be dis-v posed between the balls and bases and to be supported on thebases of two adjacent rails, the plates when thus mounted having their wings disposed closely adjacent to the webs of the rails and having their upper surfaces disposed. inline with the upper surfaces of the balls of.4 said rails so that vibration usually caused by moving vehicles on crossings maybe practically eliminated.

The invention also includes a third rail disposed midway between and approximately parallel witlrthe track rails so that the plates may havea lesser width to per mit them to be constructed of thin material, said plates, on account.y ofl the construction provided, being adapted to adequately sus; tain all stresses incident to travel, the third rail having a suitable length and preferably corresponding tothe t'onn, in crossscction, of the track rails. Alsocthe invention includes reinforcing ribs for the plates, said ribs bein r arranged for a support upon the bases of t ie trackrails.

While the invention includes structural parte' providing a permanent crossing as a feature oi' durability, these parts, or so many as is nccessary'i may be readily removed `to pcrniit removal of a broken track rail or for repairs of a rail joint, and the plates provide housings for the rail joints and their usual attachments.-

.lWith theforegoing objects in view and others to be mentioned the invention pre- Y sente a novel and useful construction, comscribed herein and claimed and as' illustrated in the accompanying drawings, it being understood that changes inform, size,

roportion of parts and.'minor details -may lie made as found to be of advantage, said changes being within the scope of the invention as claimed.

In the drawing, Fig. 1 is a plan view of railroad highway croing sliowing`-one bination and arrangement of parts as deembodiment ofthe invention. Fig. 2 is a sectional detail showing insulation between the plates, 'for use in connection with a block signal system.4 Figs. 3 and 4 are de-l tails relating to Fig. 5. Fig. 3 isV a side view of a bearing-plate showing a groove for receivingthe Harige of ,a car wheel. Fig. 4 is a view showing the opposite side of said plate. Fig. 5 is a sectional view on line 5-5 of Fig. 1. Fig. 6 is a'fsectional `View on line 6-6 of 1.

Fig. 9.is a Ysectional viewshow-ingv a modified arrangement for connecting the plates.

Referring now Vto the drawing for a more lparticular .(lescription, the invention is shown and described in connection with the railway ties 10 and the parallel track rails A and B thereon, the ball of each 'track-rail.

being indicated at 11, its base being indicated at 12 and. its web being indicated at 13.

For pui poses of the invention I provide a third rail O adapted to be disposed approximately parallel with and midway between the track rails A and B. Numerals .14 and 15 indicate bearing-plates disposed between the rail C and track rail A, each plate havingwings or flanges 16 projecting downwardly' from its longitudinal'ed es and having its lower side provided with ribs 17. each rib being disposed transversely of a plate. While I haveshown only two of these plates, any desired number may be employed, depending upon the width offa' crossing, and said .plates `may have I sliding movements -on the' bases of the rails'A and* C `when building a crossing or when it mlghtbe necessary to removes. broken track rail; and blocks 18 may be secured'ito-,ilthc rail at ythe vends of theV plates to prevent creeping. vThese plates are provideduwith grooves 19 tor receiving theflanges'ofcar wheels.

I provide additionalrails D and E, these j and being outwardly of Aand approxi matel parallel with the resfbective rails A ,While said rails and E are shownfto be'sixnilar to ordina track rails, this feature is not important, and inverted T-rails may be used for this purpose if desired f ff:

Numerals 20 and 21 indicate bearinglates adapted to have slidingmovements or theirmounting between rails A and ll shown best in Fig. 5 of vthe drhwin s, their wings 22ybeing supportedV on' the ases of said rails, said plates being provided, transversely,`w`ith reinforcing-ribs 23 similar to those described. i

Numerals 24, 25`and 26 indicatebearin plates disposed between the rails B and and they are rovided at 'their longitudinal edges with wings 16 and ribanl'?, for a support on the bases of said rails `l and C, the same. as described. i M, l Numerals 27, 28 and 29 indicate bearingplates disposed between therailsq and E, each being provided with wings 16 and ribs 17 enga ing the bases l12 of said rails.

As in icated at ie, the ends of the plates at the res ective sides of the cgossing are inclined` ownwardly, this being the preferred construction to provide closures, and bein 'of advantage to avoid injury which mig t occur from loose parts occasionally carried by moving trains, and to prevent accumulations beneath the crossing of sand, dust or snow. j

It will be appreciated that the movable feature for the plates operates'to advantage since it might be necessary to remove `a dama ed rail or to repair a rail joint, the fish-p tes for the latter being indicated at 30.

The plates 20 and 21 may have outward sliding movements for their removal after the blbocks 18 have been detached Yfrom the rail A. Also, after detaching the blocks 18 the- plates 14, 15,` 24, 26, 27 and 29 may 'be removed by causing them to slide outwardly.

The plates 25 and 28, which cover the rail joint, may have rocking movements to eii'ect their removal, it only being necessary to move the distance.

In order that sand, dust or other similar substances will not move downwardly between the ends of the plates, suitable ianges f and recesses g are providedfor their abutting' ends, said flanges being adapted toengage in the recesses when the parts are assembled as a complete crossing. Also other cri-operating fastening devices are provided, as, for instance, projections h ada ted to enter apertures k which are provide for the abutting ends of the plates. While, as shown in the drawing, these last named fastening devices` are provided for'the ribs of two adjacent plates, they may be provided plates 24, 26, 27 and 29 a limited for other parts o f the plates; alsot'he projectionsh may-be of any suitable proporf tions, the recesseshaving such proportions required width, and while it is shown as a crossi-ngfor a single track it, of course, may have a length sufiicientto cross any required numberA of tracks. Numerals' 31 indicate approaches to the-crossing which may be constructed of any suitable material.

InFig. 2 a pairwof horizontal vbeams 32 are shown as a substitute for tlie rail'C, and x between thesebcams is disposed an insulat ing plate 33 adapted for use in instances where a railway is operating under a blocksignal system, it being. assumed that the `plates lf and 25 are of metallic construction' and therefore would operate as electrical conductors between the rails A and B.

. While the rail C is of advantage in the construction of the herein described crossing, it could be dispensed with if plates of:v

` considerable thickness were used, and there- `fore I do not wish to be limited -to the use of said rail.`

Fig. 9 illustrates a modified form of the invention since the wings 16 of the bearin plate 25 are provided at one of their en s with recesses g and k, the wings'at its op: posite end being provided with projections f and h. This construction is clearly within the scope of thel invention and it permits the projections f and h of the bearing-plate 24 to enter recesses -g and 7c of the bearin plate 26 after the plate 25 has been remove,

this feature being an advantage in manu- Yfacturing'or production to permit interchange -of the plates.

While I have shown and described a rail C between two track rails and identified it as a third rail, it is obvious that the scope of the invention permits more vthan a single rail C to be employed, and I do not Wish 'to limit myself to the employment of a sin lerail C.
