Application filed March 13, 1917. Serial No. 154,630.

T0 nZZ 'whom nvay/ Concern Be it known that I, @Hannes F. BnowN, a citizen ot' the United States, residing at Salt Lake City, in th@ county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Railway -Road-Beds, of which the following is a specification.

My invention relates to railway tracks and has for its object to provide a drained and paved roadbed which will prevent the disintegration of the pavement adjacent to rails.

These objects I accomplish with thc improved roadbed illustrated in the accompanying drawings in which similar letters and numerals of reference indicate like parts throughout the several figures and as described in the specilication forming a part or' this application and pointed out in the appended claims.

In the drawings in which I have shown a substantial embodiment of my invention Figure 1 is a vertical section of a portion o1 the roadbed and a rail thereon with a portion of a tie in dotted lines. Fig. EZ is a side eleva-l tion ot one of the rail shields or cover plates. Fig. 3 is a transverse section of one of said plates. Fig. l is a plan view of one ot said plates or shields. Fig. 5 is a plan view of a portion of a railway track with portions of the shields cut away, and removed from the roadbed.

0n paved streets and roads it has been found extremely difficult to lay a railway track with the pavement close to the rails which pavement will not be disintegrated by water passing down at the sides of the rails and accumulating under the rails and ties and then freezing and expanding the ties, water and adjacent portions of the roadbed and bulging the pavement. The present invention is intended to direct the water from sprinkling, rains or melted snows downward by the rails and ties and into a. tile pipe or other drain pipe and away, thus removing the water from the roadbed before it has time to freeze, and consists of sheet metal angle plates C, which are placed adjacent to the web and base flanges of the rails B. The said plates C have portions thereof struck as spacing lugs Gr from the inclosed angle side which lugs Gr bear against the web and base iange of the rails to space said plates from the rails to allow water to pass downward. by the rails when Said ,rails are secured on. the ties Q. Portions ot said plates are struck in the opposite direction to form the pavement engaging lugs II and J and whereby through the grouting and binding material K the said plates C may be securely fastened to the pavement. Vertical openings- D are provided in and through the concrete M to convey the water downward into and through the layer of pea gravel N, to be carried away through the drain pipe A.. In order that said openings D may not become clogged and to form a. longitudinal water channel the lower portion of said plates C are curved upwardly at E.

The roadbed is constructed by excavating the earth l? and filling a portion of said eX.- cavation with pea gravel N in which is laid a drain pipe A. on one or both sides of the road as desired. Under the track portion of the roadbed a hed of concrete 'Il may be laid if desired. 'Ihe bed of pea gravel N covers said concrete T as well as surrounding the said drain pipe A. @n the top of the layer o'fpea gravel is placed a bed oi concrete M with holes D formed therein which partially surrounds the ties Q. @n a portion of the said concrete M adjacent the rails a grouting and binding material K is laid, a portion of which adheres to the said lugs IFI and I of the angle plates C, and on which the pavement .is laid, the kind shown being asphaltum and stone blocks. Adjacent the tread ot the rails stone pavement blocks L may be laid if desired or the asphaltum covering may fill the space shown as L.

Having thus described my invention I dcsire to secure by Letters Patent and claim l. A railway roadbed consisting of a ce ment concrete layer having a plurality of vertical holes therethrough; ties resting in said concrete to support rails; spaced apart angle plates adjacent the web and. base flanges of rails carried on said ties; lugs struck outwardly from said plates; and a cementitious paving strata covering said concrete and engaging with said lugs and bearing against said plates.

2. A. railway roadbed consisting of a layer ot cement concrete having a plurality of vertical openings therethrough; ties partially surrounded by and resting in said concrete; angle plates spaced from rails fastened on said ties; lugs struck Jfrom said angle plates to space them from the rails and to engage with a cementitious paving strata; a convex portion of said. plates to forni a was` lio ter channel leading to said openings in said concrete; and a surface strata covering said concrete and abutting aga-inst the outer side of said plates at their upper edges.

3. A railway track consisting of a layer 0f gravel Within which is placed a drain pipe; a layer of concrete on said gravel and having a plurality of vertical openings therethrough; ties partially surrounded by said concrete and resting on said gravel; rails fastened on said ties; opposed sheet metal angle plates spaced from the web and flange portion ot' said rails; lugs integral with said plates; a cement grouting engaging With said lugs and resting on said cement eoncrete; an are shaped longitudinally disposed' portion of said plates spaced above the openings in said concrete; and a surface strata resting on and adhering to said grouting and concrete.

t. A railway roadloed comprising a drainage layer of gravel; a drain pipe therein: a layer of concrete on said gravel and having a plurality of openings therethrough; opposed sheet nietal plates having a portion ot' each4 Curved upwardly as a covering oi said openings in said concrete; lugs struck from said plates; a eenient grouting engaging With and adhering to said lugs; and a surface strata supported by said concrete and grouting.

In testimony whereof I have affixed my signature in presence of a witness.
