Application filed; July 13,

T00 whom it may concemf] Be it known that We, V. VA'N' DOREN and PETER O. HErrMANN, citizens of the United Statesof America, and residents, respectively, of 'Burling'ame, county of San Mateo, and State ,of'C-alifornia, and San Francisco, county of San Francisco,v and State of California have inventedYa new and Improved Railroad Crossing, of which the followingis a description. p Our invention relates to a railroadicrossing and the invention has for its general object to provide a railroad crossing improved in various particulars, whereby the weight of the roadbed both between the rails of a track and outside of the track is supported through the medium of the rails on a supporting assemblage beneath the track and whereby the bed is prevented from umping movements.

A further object of the invention is to stifl'en the rails" through the medium of the bedsupporting means and also to provide in connection with the portion of thebed outside of the rails pier supports along the outer edge of said bed portion and to: so arrange the bed and supporting meansthat the 'up and-down motion of therails is converted into angular motion in the-outer bed portion with .outer, pier supports; as fulcrums or centers. The manner and means whereby the above and other objects are attained will clearly appear from the Reference is to behad to'the accompany ing drawingsforminga part of this specification, it being 'understood that the drawings are merely'illustrative of two examples of the invention. 7 1 V Figure 1 is a transverse vertical section of a railroad crossing constructed in accordance with our invention, the plane of the section being indicated by the line 1-1 in Figure 2; i I

Figure 2 is a fragmentary plan view" with parts of the roadbedbroken out;

Figure 3 is av detail in longitudinal vertical section as, indicated by thelline 3+3, Figure 1;

Figure 4 is a fragmentary transverse vertical section illustrating the modified form of roadbed on our novel supporting elements.

In embodying our invention in a railroad crossing in accordance with the illustrated example we provide a transverse supporting element 10 extending between the rails A of a track. The supporting elements 10 have end projections 11 to overlie and rest upon the opposed rail flanges. At the outsideof the rails we provide transverse supporting members 12 each of which at one end has a projection 13 to! overlap and rest upona rail flange and at the opposite end each-supporting element 12 has a projection 14: which rests and has support upon a shoulder 15 of aconcrete pier 16 disposed outside of the outer bediportion of the crossing. Between the tracks a concrete pier 17- vis provided in'the crossing and formed withshoulders lS tojform rests for the outer ends 14 iofth'e bed portions'be tween tWo tracks. Thus, the supporting element 10 is disposed between the rails of eachtrack and a supporting element 12 outside of the rails of each track. A pier "17 is provided "between'the two adjacent tracks and piers 16 at the outer sides of the outermost bed portions of the crossing.

' The adjacentends of transverse elements 12 are linked together by supportingbars 19 extending beneath each track rail A trans versely thereof. The supporting bars 19 prevent: depression of the track rails and transfer the load to the transverse elements 10 and 12 while'the engagement of the projecting ends 11 and 13 withl the rail flanges prevents undue jumping of the track rail or vertical displacement thereof. In the case of the elements 12, which have support at their outer endson the concrete piers 16 or 17, in

responding to vertical play of the rails,

numeral'23' indicates bolts fastening the ends of the suppor'ting bars 19"to the elements 10 and 12. At the inner and outer sides of each bed portion formed by the planks 20, that is to say, the bed between adjacent tracks, and outside of the outermost rails,

concrete, cement, or the like.

Each'of the'elements 1O, 12 is given a truss shape for strength and the lower edge is'made V-shaped as shown in section, Figure 3, so as to not materially disturb the ballast of the roadbed by the up-and-down movements as the train'rolls over the track.

WVe would state in conclusion that while the illustrated examples constitute practical embodiments of our lnvention, we do not limit ourselves strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described our invention, we claim:

-1. In a railway structure, transverse supporting elements adapted to be positioned between rails of a track and of a length to rest on the flanges of the 1'ails, transverse supporting elements adapted to be disposed outside of the rails of the track, means to support the second-mentioned transverse elements at one end on the flangesof'the adjacent rails, fixed means to support the opposite ends of said second-mentioned supporting elements, and-means linking the adjacentends of the first-mentioned and second-mentioned transverse elements and affording support for the track rails.

2. In a railway structure, transversesupporting elements adapted to be positioned between rails of a track and of a length to rest on the flanges of the rails, transverse supporting elements adapted to be disposed outside of the rails of the track, means to support the second-mentioned transverse ele ments at one end on the flanges of'the adjacent rails, fixed means to support the 0p posite ends of said second-mentioned supporting elements, means linking, the adjacent ends of the first-mentioned and secondmentioned transverse elements and 'afiording support for the track rails, and longitudinally' disposed bars above and secured to-said transverse elements adapted to receive a roa'dbed between said bars.

3. In a railway structure, transverse-supp0rting., elements adapted to be positioned between rails of a track and of a length to rest on the flanges of the rails, transverse supporting elements adapted to be disposed outside of the rails ofthetrack, meansto support the second-mentioned transverse elements at one end on the flanges of the adjacent rails, fixed means to support the opposite ends of said second-mentioned supporting elements, means linking the adjacent end of the first-mentioned and second-mentioned transverse elements and afiording support for the track rails, longitudinally disposed angle bars, means fastening said angle bars tothe transverse supporting elements adjacent to the ends of the latter, and

'a roadbed forming a filling between the angle bars.

4; In a' railway structure, transverse supporting elements having members adapted to rest on the flanges of the rails of a track, transverse supporting elements adapted to be disposed outside of the track rails and having members at one end adapted to rest on the flanges of the rails, and piers on which the opposite ends of said second-mentioned transverse elements rest and are afforded vertical movement with the rest points on the piers as centers.

5. In a railway structure, transverse bedsupporting elements adapted to be disposed outside of the rails of a track and having .members at one end to rest on the adjacent flanges of the track rails, and piers on which the opposite ends of said transverse supporting elements may have rocking vertical movement.

6. In a railway structure, transverse supporting elements adapted to be disposed at opposite sides ofa track rail to afi'ord support for a roadbed, and links'co'nnecting the adjacent ends of said supporting elements and affording support for a rail.

7. Ina railway, bed portions between the rails, bed portions outside of the rails, transverse elements affording supports for said bed portions, and means linking the inside bed supports and outside bed supports and adapted to'seat the railway rails.

8. In a'railway, bed portions between the rails, bed portions outside of the rails, transverse elements affording supports for said bed portions, and means'linking the inside bed supports and outside bed supports and adapted to seat the railway rails; together with fixedflpiers'forming rests for the outer bed supports at the outer ends thereof on which'piers the said bed supports are per mitt'ed'v'ertic'al rocking "movement.
