Patented Feb. 16, 1932 V UNITED STATES PATE OFFICE" JOSEPH J. woacmonowsxr, or GUDAHY,- wrsoonsim Assronon To A. o. smrrn CORPORATION, or MILWAUKEE, WISCONSIN, a CORPORATION on NEW YORK RAILWAY GRADE CROSSI'LNG; CONSTRUCTION Application filed March 28, 1931 Serial No. 525,946.

This invention relates to sheet metal rail- Wa grade crossing construction.

ne of the objects of the invention is to provide a sheet metal railwaycrossing for which the supporting ties need notloe uniformly spaced part. V

Another object is to provide such a crossing whichmay be l'eadil adapted for em ployment with rails of di erent heights.

Referring now to the drawings wherein is illustrated a preferred embodiment of the invention,

Figure 1 is an end elevation of a portion of a railway crossing constructed according to the present invention, parts. being shown in section for the purpose of clearness; r h Fig. 2 is a longitudinal section thereof taken on a plane indicated by the line 22 in Fig. 1; h

Fig. 3 is a topiplan view of Fig.1, certain parts being" omitted, and others shown in section for the purpose of clearness; and Fig. 4 is a fragmentary perspective View of one of the carrier bars.

Referring now more particularly to the drawings, the reference character indicates one of a pair of rails of a railroad track which are secured to cross ties 11 in any suitable manner. Secured to the cross ties 11 by means of spikes 12 and extending parallel to the rails 10 are carrier bars 13.

The carrier bars 13 Iaremade of sheet 1 metal in the form of channels having upper horizontal web portions 14 anddownwardly extending supporting side. walls 15. The side walls 15 have their lower edge portions bent inwardly toward each other in aplane parallel to theupper web 14 to. form flanges 16 which constitute means for providing substantial bearing surface for the carrier members and also to serve as means for securing the same in position. a h

In securing thecarrier bars 13 tofthe cross ties. 11, the spikes 12 are passed through alignedholes 17 and 18in the webportion 14 and bearing flanges 16, respectively and driven into the cross ties 11. This manner of securing the carrier bars to the ties prem vents spreading of the side Walls thereof dur upper web thereof predetermined intermeans an securingthe same in position on ing passage of heavy loads over the cross- Thecarrier bars areprovided with pairs of ears 20 which are struckup from the j u vals to providefimeans for securing tie bars.

21thereto.j The tie bars 21 are also made of sheet metalin the form of channels and have upper horizontal web portions 22 and downwardly extending side walls 23. The side walls 23 have their lower edge portions bent inwardly toward each other in a plane paralleltothe uppen web 22 to formflanges 2 1 whi'chprovide substantial bearing surfaces forthe tie bars andalso serve as the carrier bars.

. inturned flangesQt of the bars are adapted to underlie the pairs of struck up cars 20 of the carrier bars to maintain the tie barsin adjusted jposition. The bearing flanges 2 1 01 the tie bars 21 have notches 25cut1inthem at intervals corresponding to the spacing of the carrier bars13,thus per mitting the tie barsjto he slipped over the struck up ears 20 and moved endwise over the Webs 14 into theirifinally adjusted positions. lVhen the tie bars are. thus positioned, the "flanges 2 1". interlock. with the struck up ears 20 to prevent vertical or lateral movementof the tie bar relative to the carrier'bar, v i

The tie bars 21 are provided with a plurality of pair sfofears 26 which 'are struck up from thesupper web thereof to provide means for securing crossing elements 27 thereto in parallel juxtaposed relation. The crossing elements 27 have inturned bearing flanges 28 which are adapted to underlie the struck up ears 26 ofthe tie bar to secure the crossing elements in adjustedjposition. The bearing flanges 28 of the crossing elements have notches 29 at spaced intervals correspending to thefldistance between the pairs of struck up ears 20 on carrier bars 13. y

; In'the installation of a crossing, the carrier bars13 are first secured by spikes 12 to the cross ties 11 with corresponding pairs of struckup ears 20 of the several carrier bars in cross alignment; The tie bars are then tohold the tie bars in position. The several tie ;bars are so adjusted in position that corresponding pairs of struck up ears 26 of the several tie bars are in crossalignmentr Crossing elements 27 are then secured to the tie bars in a manner similar to-the securing of the tie bars to the carrier bars. 7 v

' By providing the carrier bars 13, a tie bar 21 need not be positioned directly above a cross tie 11 as is thecase when no carrier bars are used, thereby expediting the installation of'a crossing at. a place where the cross ties are non-uniformly spaced or are spaced in such a manner as to make it impossible to locate the tie bars in the proper position.

' Furthermore, by providing carrier bars of different heights it is possible to adapt the crossing to use with rails of correspondingly different, height-s without necessitating a change in the height of the tiebars or crossing elements.

Although the foregoing description is necessarily of a detailed character in order to completely set forth the invention,it is to be understood that the specific terminology is not intended to be restrictive or confining and it is to be further understood that various rearrangements of parts and modifications of structural detail may be resorted to without departing from'the scope or spirit of the invention as herein claimed.

' .Having thus described the invention, what isclairned anddesired to be secured by Letters Patent is:

v 1. In a sheet metal railway grade crossing, the combination with the rails and ties of sheet metal carrier bars extending substantially parallel to the rails and fastened to the ties, sheet metal tie bars extending transversely to said carrier bars and supported thereby, means integral with said carrier bars and tie bars for interlocking the same and preventing relative vertical movement,

and crossing elements supported upon said tie bars and fastened thereto in parallel juxtaposed relation to provide a tread surface substantially flush with the. tops of the rails.

2. In a sheet metal railway grade crossing,

the combination with the railsandties of sheet metal channel shaped carrier bars extending substantially parallel to the rails and fastenedto the ties, sheet metal channel shaped tie bars extending transversely'to said carrier. bars andsupported thereby, means integral with said carrier-barsand tie bars for interlocking the same and preventing relative vertical movement, and crossing elements supported upon said tie bars and fastened thereto in parallel juxtaposed relation to provide atread surface substantially flush with the tops of the rails.

3. In a sheet metal railway grade crossing, the combination with the rails and ties of sheet metal channel shaped carrier bars extending substantially parallel to the rails and fastened to the ties, said-carrier bars having relative vertical movement, and sheet metal channel shaped crossing elements extending longitudinally of the rails and in juxtaposed relation to provide a tread surface, said'crossing elemnts having means for fastening the same to said tie bars; i
