Application filed January 30, 1911. Serial No. 605,418.

To all whom it may concern:

Be it known that I, J orm N: D. BROWN, a citizen of the United States, residing at Anadarko, in the county of Caddo and State of Oklahoma, have invented new and useful Improvements in Railway Road-Bed and Track Construction, of which the following is a specification.

My invention relates to improvements in railway road-bed and track construction and the object of the invention is to simplify, improve and cheapen proposed methods of steel-reinforced-concreteroad-bed and track construction; to eliminate all wood ties and telegraph or'telephone poles and to reduce the quantityof concrete and steel required in such a construction to a minimum; and

to provide a construction in which the entire supporting power of the earth road-bed is utilized, and means provided by which the rail can'be removed and replaced when damaged or worn without disturbing any other part of the construction; and also to provide the resiliency necessary in a safe perspective lineal view of a section of the rail-chair and rail showing manner of joining the ends of rail-chair. Fig. 3 is a modification of Fig. 1 in which the exposed tierod of Fig. 1 is eliminated and the rein-.

forced concretebetween the railsraised to as near the top Oflfliil-Chall'fiS practicable. Fig. 4 is a vertical cross sectional view of a z 1 part of Fig, 3 adapted to street railway con- ,struction when streets are paved with any material having a concrete base.

Corres onding parts of each figure I are indicate .by likenumbers and letters.

I would provide that the parallel trenches required by my construction be dug. ten to fifteen inches deep according to character .of earth road-bed and the requirements of the construction, and that. bottom of trenches be well tamped, and if road-bed. is soft and s ngy, that the trenches be dug deeper and t e deeper part filled in with dry cla or broken stone {that when so dug'plank o the propervwidth be provided in sufiicient quan tity .for one days construction, and thatv three-quarters. of" an inch holes be boredin the plank one-half inch deep and one. one-half inches from the bottom of same, and

Line and level up the parallel established hue and grade of road-bed and gage of rails; and place the four one inch lineal reinforcing bars, as shown in-Fig. 1, and wire them to the bars (.10) near bottom of box; lap these lineal at the ends, or have one end a hook and the other an eye and thus join them; have a supply of timbers of the size and formof ,cushion (l5)three and one-half inches in the center and six inches at widest partand press the same down into the concrete while soft and before box is full; line and level these timbers up and gage them the same as you would the rails; reinforcing ing bar (9) While concrete is'soft. timbers and plank can be removed the day and carried .forward for additional The cushion (15) The next use.

Place conduit (16) when putting on the secondary coat'of concrete; it may be metal tubing on the paper composition tubing used'for such a purpose. Place manholes at suitable intervals and provide covers or same to keep out water and dust. To provide for unequal expansion and contraction of rail and rail-chair the bolt or rivet holes should be slightly elongated from the center 'of rail-chair toward the ends; if the bolt or rivet nearest the center of rail-chair fits snug there can be no-cree ing of rails. To prevent creeping of railchairs rivet a piece of steel, of suitable form, width and length, on the inside ofrail-chairs at'center of same and at right angles thereto.

In order to break joints of rails and rail chairs, I provide for the alternate use of different lengths of rails and rail-chairs. If one length is thirty feet-I would make the other length forty feet; place the center of the thirty foot rail over the center of the forty-foot rail chair and the center of the forty-foot rail over the center of the thirty foot rail chair and have the center bolts or rivets fit snugly while all other bolt or rivet holes in the rail chairs are slightly elongated.

To change the rails when worn or damaged remove the bolts wherebolts are .used or punch out the rivets.

For drainage of space between rails, construction collects the water in center ,of track, and I provide for disposing of same through sewer pipe by conducting it down bases, or through the same when necessary, the local conditions would suggest. My construction is adapted to'either new construction or the reconstruction of existreconstruction is pro.-

In my construction, after material isprovided in the proper form, no skilled labor' would be required other than the concrete and cementboss, the track construction boss and the .civil engineer to levels.

, Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. The combination in a railway road-bed and track construction of parallel steelreinforced-concrete. stringers; called primary concrete, united and connected by. av secondary coat of steel-reinforced concrete extending, and covering the surface of earth roadbed, between [the rails, and having steelreinforcing bars placed across said stringers with lineal steel reinforcing bars resting thereon and nearthe" bottom ofstringers, and 'havingwertical steel-reinforcing bars placed at intervals to bindthe'primary and secondary concrete together, and having horizontal steel-reinforcing bars so placed as to bind the concrete stringers to: the congive lines and crete between the-rails, as and for the purpose shown and specified.

2. The combination in a railway roadbed and track construction of parallel steelreinforced concrete stringers, called primary concrete, united and connected by-a secondary coat of steel-reinforced concrete eXtending, and covering the surface of earth roadbed, between the rails, and having a cushion of resilient materials embedded in said stringers and continuous therewith, said cushion having resting thereon, a rail-chair having a curved base and an upright arm which carries the rail and to which the rail is bolted or riveted, as and for the purpose shown andspecified.

3. The combination with a railway reinforced concrete road-bed of a track construction having parallel continuous rail chairs connected and held in gage by crossed and incased reinforcing'bars riveted to said rail chairs; said rail chairs comprising'a base,

resting. on a cushion," and an upright arm which" carries-a new form of rail in which the base and web of the old form of rail is cut away and'the head narrowed and elonglzlited oh the lower side and havin a groove t erein which fits over the uprig t arm of rail chair and is riveted thereto, as and for the purpose specified.

4. The combination in a railway roadbed and track construction of concrete,

strengthened laterally by steel reinforcingzflfi bars and tie rods and lineally by steel re-- inforcin'g bars and rail chairs and a: conduit; said concrete having parallel cushions embedded therein and rail chairs supportedthereon; said rail chairs united and held in gage by a tie rod and reinforcing bars riveted thereto, as and for the purpose specified.

5. The combination .in a railway road bed and track construction of reinforced parallel concrete stringers in connection 76 with the concrete base of street paving; said stringers having a cushion thereon upon which a rail chair rests; said rail chair having a curved base and an upright arm with a new form of rail fitted thereon and bolted 8g thereto; having 'the paving materials brought up flushwith the top of the rail, except a p a -a row of paving brick so placed as to proce for the flange of wheels, and

vide a means of. getting at the rail bolts and t-hecover t0 manhole to conduit; and embedded tie rods placed at intervals to,- bind rail-chairs together and hold the rails ,in gage, as and for the purpose specified.
