UNITED STAT ES PATENT OFFICE OLUF'F. JENSEN, OF COUNCIL BIQUFFS', IOWA, ASSIGNOR, BY REE-SITE ASSIGNMENT-S; T0 LOCOMOTIVE FINISHED MATERIAL COMPANY, OF ATGHISON, KANSAS; Ii CORPORA- TION OF KANSAS Original No. 1 ,5'5'7,590, dated This invention relates tohighvvay crossingso'ver railway tracks, and has for its objectto provide slidable and rotatable plates'ivhich may be used in connection with the railway ties and track rails said plates being of such prop'ortioi'i' that they nayfbe prepared in stock ready foruse and may be coi'ivenientl'y mounted between the track rails to" provide a complete, permanent crossing at a less expense of time" than ordinary.

I 1 The invention broadly includes the use of comparatively thin bearing-plates having flanges or Wings projecting downwardly from theirlongitudinal edges to'be disp osed between the balls and b ases and to be supported on the bases 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 in linewith the upper surfaces oftheballs of said rails so that vibration usually caused by'nioving' vehicles on crossings may be practically eliminated. p

The invention also includes a third rail disposed midway betweenand approximately parallel with the track rails so that the" plates mayh'ave a lesser Width to pcrmit tfhein' to be constructed'ofthinmaterial, said plates, on account of the construction provided, being adapted to adequately sustain allstrcsses incident to travel", the third rail h aving a suitablelength and preferably corres riondingto the forln in cross sect-ion, of the track ra' Also the invei'ition includes reinforcing i be for the plates, said ribs being arranged for a support upon the basesotthetra'ck rails.

VVhil e the invention includes structural parts providing apermanent crossing as a feature of durability, these parts, or so many as is necessary, maybe readily removed to- I permit removalof a broken tracli' rail or for repairs of a rail j'oint, and" the plates providej housings for the rail oints and their usual attachments.

With the foregoing objects in viewand others/to be mentioned the invention presents a novel and useful construction, comb nation and arrangements of parts as described here in and claimed and as illustrated inlthe ac-;

coinpanying drawings, it being understood that changes in form, size, proportion of parts minor details may be madeas found to be of advantage, said changes being RAILWAY HIGHWAY CROSSING. v v

Serial No. 205,955.

Withinth'e scope of the invention as claimed.

Figure 2 is a sectional detail showing insu- I lat-ion between the plates, for use in connection with a block signal system;

'Ke'terring now to the drawing tor-ta more particular description the invention is'sh-own and described in connection with the railiv'av ties 1'0 and the parallel track rails A and B thereon, the ball of each track rail being in-' dicated at 11, itsbase" being indicated at 12 and its Web being indicated at 13; v

For purposes of the invention I provide a" third rail 0 of substantially the lengtli' cor responding to the Width of the highway adapted to be disposed approximately p arallel with and midway between the track rails A and B. Nunmtnlhld and 15 indie ebear ing plates disposed between their track rail A, each plate having Wings or. c

flanges 16 projecting, downwardly from its longitudinal edges and having its Tower side provided With ribs 17;, each rib being dis posed transversely of a plate. While I have shown only two otthese' plates, any desired number may I be employed, depending upon;

I provide additional rails D and E, these being disposed outwardly of and approxi mately parallel with the respective rails A and B. While said rails D and E are shown to be similar to ordinary track rails, this feature is not important, and inverted T-rails may be used for this purpose if desired.

Numerals 20 and 21 indicate bearing plates adapted to have sliding movements for their mounting between rails A and D shown best in Figure 5 of the drawings, their wings 22 being supported on the bases of said rails, said plates being provided, transversely, with reinforcing ribs 23 similar to those described.

Numerals 24, 25 and 26 indicate bearing plates disposed between the rails B and C, and they are provided at their longitudinal edges with wings 16 and ribs 17 for a support on the bases of said rails B and C, the same as described. I

Numerals 27, 28 and 29 indicate bearing plates disposed between the rails B and E, each being provided with wings 16 and ribs 17 engaging the bases 12 of said rails.

As indicated at c, the ends of the plates at the respective sides of the crossing are inelined downwardly, this being the preferred construction to provide closures, and being of advantage to avoid injury which might oeone from loose parts occasionally carried by moving trains, and to prevent accumulations beneath the crossing of sand, dust or snow.

It will be appreciated that the movable feature for the plates operates to advantage since it might be necessary to remove a damaged rail or to repair a rail'joint, the fishplates for the latter being indicated at 30. I

The plates 20 and 21 may have outwart sliding movements for their removal after the blocks 18 have been detached from 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 effect their removal, it only being necessary to move the plates 24, 26, 27 and 29 a limited distance.

In order that sand, dust or other similar substances will not move downwardly between the ends of the plates, suitable flanges f and recesses g are provided for their abutting'ends, said flanges'being adapted to engage in the recesses when the parts are assembled as a complete crossing. Also other cooperating fastening devices are provided, as for instance, projections h adapted to en ter apertures k which are provided 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 adj acent plates, they may be provided for other parts of the plates; also the projections it may be of any suitableproportions, the recesses having such proportions that they will receive said projections, the object in view being to prevent undue vibration of the plates when subjected to'stresses directed thereto.

The crossing as described may have any required width, and while it is shown as a crossing for a single track it, of course, may have a length sufficient to cross any required number of tracks. Numerals 31 indicate approaches to the crossing which may be constructed of any suitable material.

In Figure 2 a pair of horizontal beams 32 are shown as a substitute for the rail C, and between these beams is disposed an insulating plate 33 adapted for use in instances where a railway is operating under a. block signal system, it being assumed that the plates 15 and 25 are of metallic construction and there fore would operate as electrical conductors between the rails A and B.

l Vhile the rail 0 is of advantage in the construction of the herein described crossing, it could be dispensed with if plates of considerable thickness were used, and therefore I do not wish to be limited to the use of-said rail.

Figure 9 illustrates a modified form of the invention since the wings 16 of the bearing plate 25 are provided at one of their ends with recesses g and 7c, the wings at its opposite end being provided with projections 7 and h. This construction is clearly within the scope of the invention and it permits the projections 7 and h of the bearing plate 24 to enter recesses g and 7c of the bearing plate 26 after the plate 25 has been removed, this feature being an advantage in manufacturing or productionto permit interchange of the plates.

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

I claim as my invention-- 1.
