RAILWAY-ROAD-BED CONSTRUCTION.

Specification of LettersPatent.

Patented Apr. 9, 1918.

Application filed July 18, 1917. Serial No. 181,328.

To all whom 'it may concern:

Be it known that I,- JAMES DELos NEGUS, a citizen of the United States, residing at Douglas, in the county of Converse and State vof Wyoming, have invented new and useful Improvements in Railway-Road-Bed Construction, of which the following is a specification.

This invention relates to improvements 1n the construction of railway road beds, the object of the invention being to provide a road bed having a water proof covering for the surface of the bed proper, as well as the major portions of the ties, together with all embankments, excavations, drainage ditches, ctc., alongside the road bed, and which water-proof covering will be so constructed as to facilitate't-he drainage off of the water,

thereby keeping the road bed continually dry and diminishing the rusting of the rails and other metallic parts of the road structure, and at the same time preventing rotting of the ties and the undermining or loosening of the soil from the action of water and the results incident thereto.

A further object of the invention is to provide a road bed structure which will reduce the cost of repairs and 11p-keep of the tracks, etc., will maintain the alinement of the rails and the established grade to prevent derailments and other accidents, which will reduce the amount of dust deposited and set into motion by the travel of a passing train, which will prevent the growth of grass, weeds, etc., 1n the road bed, which will obviate liability of danger of ire reaching and attacking the ties and which will insure greater resiliency of the rails vand greater comfort in travel thereover, with a inal gain in the cost of construction and maintenance of the road bed and track notwithstanding any primary increased cost under some conditions.

With these and other objects in view, the invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings in which Figure l is a top plan view of a section of a. railway road bed and track embodying the principles of my invention. Y

Fig. 2 1s a vertical longitudinal section taken centrally between the track rails as indicated by the line 2 2 of Fig. 1.

Fig. 3 is a vertical transverse section taken on a plane between ties, as indicated by the line 3-3 of Fig. l.

Fig. 4 is a vertical transverse section on the line 4 4 of Fig. l, taken on the line of one of the ties. y

Fig. 5 is a section on the line 5-5 of Fig. 1.

Referring to the drawings, 1 designates the 'earth base or other foundation, 2 the ties and 3 the track rails of the road bed and track construction, the rails being secured to the ties in the ordinary or any preferred manner, as byv the use of spikes or other similar fastenings 4.

The ties 2, which may be .of woodor metal, but preferably of wood, are embedded in the foundation l up to a point adjacent to the tops of the ties, the latter projecting just sufficiently above the general line of the surface of the trackway to support the rails in a sufficiently elevated position. As shown, the entire road bed, consisting of the surface of the foundation lbetween the rails and ties and laterally beyond the same to the base of the embankment forming the road bed is provided with a cove-ring 5 of waterproof material. This covering 5 is pref erably and ordinarily from one to two inches in depth and consists of a fine concrete cement, composed of one part of good hydraulic cement and three parts of good silica sand or cement applied and compacted by the use of an ordinary cement gun or in any suitable manner. This layer of concrete covers the surface of the earth throughout the entire area of the droad` bed and the sides of the ties up to the level of the rails, thus preventing the water from reaching the sides of the ties and rottingthe same. The water-proof surface also prevents the rain or other water from reaching any part of the road bed, thus preventing' the earth fromA becoming loosened and so tened up, or of being washed away or undermined in any manner, whereby a solid and compact roadway will at all times be secured. i

For the purpose of protecting the tops of the ties and sealing the openings formed by the rail spikes or fastenings, the exposed surfaces of the ties may be coated with tar, pitch or any ,other suitable like waterproofing coating, which may be fired in about the spikes to prevent the entrance of moisture to incas/is tially independent of the coveringY between the ties, and the latter are permitted to vibrate on the soft earth bed irovidino' necesa i-l sary resiliency and preventing fracture of the covering. rl e latter, being formed of'y concrete, of course maintains aliard surfaceat all times, and if this covering were continuous it heavy enough would destroy all resiliency.

ln practice, a strip of sheet metal may be temporarily placed in position ior forming the abrupt edge portions of the covering ot' the ties..

The bed being thoroughly protected, it maintains its original condition indefinitely, the ballast, bed, and covering cooperating in the production of an ideal track construction. Furthermore, the creepingv of the tie-s is prevented by the bracing effect of the concrete between ties.

ln addition to the use of' a watenproofcovering for the road bed, the surface of the bed is constructed in a novel manner. is shown, the spaces between 'the ties and from the center of the track bedto the ends of the ties is given a compound. slope in order to facilitatev and secure the` rapid and free drainage on? oi!l all rein water or other deposited moisture. To this end the portion of the lower bed between the adjacent ties? slopes from the inner sides olf the ties, as indicated at 6 downwardly and inwardly to a point about centrally between the tiesas indicated yat Z whereby the sloping surfaces meet each other in the form cfa depression. From the longitudinal center et the space between acentties, however, the'surfaces e slope downwardly and outwardly 'freni a point about level. with the tops or the ties. `to a grade gustabovelthebottom surfaces of the ties, as indicated in Fig. 3, from which point the sides` of the embankment forming the bed extend outwardly and' downwardly inthe form ofsloping drainage surfaces 9, whereby the rain; or other water is carried olf for disposal. 1t will, thus-be seen that the surfaces of the. r oad. way between ties slope from a centralpoint downwardly and, inwardly between the ties and downwardly and outwardly from the longitudinal center of the Space between the ties, so that all moisture will be cons ducted away fromthe sidesoi the ties and in 1 an .outward and downward direction, thus keeping the ties and surrounding, surfaces a section on theiline would either be fractured or iff at all times free from moisture. Vl`he rails 3 are also held supported above the level of the road bed and are thereby also protected from. moisture, except as to the amount deposited directlyV thereon during a rain or through the melt-ing of' the limited amount of' snow which can fall thereon, or which may be deposited thereon naturally in the forniof dew., with a result that the metallic parts of the trackway will be much less subject to rust than therails oftrackl; structuresof the ordinary ty ie. lt will be observed that on account or'Y the solidity off the road bed theuse of rcck` or other ballast is entirely unnecessary, the tiesbeing embedded; in the relative soft earth or'otherma.- terial andl thus allowed? to have a much greater resiliency or cushioning actionlthan would otherwise-be possible. Furthermore asthe greundis protected from Vthe soaking; effects or" watersinceall water will be immediately carried. oi'i'V and prevented from` accumulating, it will be evident thatthe road bed will be-at all times kept drv solid.

.m and firm. and sponginess. or looseningv-ofv the earth with, liability of the undermining o'f the track andl spreading of the rails entirely obviated.k The ties will alsobe efectuallyprotected andprevented from decaying,thus adding te the preservative integrity of the trackv structure as a whole.k @ther advantages are, that 'frequent criticalv inspection ofthe track isnot necessary, and hence that then-timber of track walkersand. section repair men may berreduced, that asiall dustl and deposits are washed away by the rain water the` raisingof. dust or grit by the passage of the rollingV stock, with attendant inconveniences and disadvantages, will,l bey wholly overcome. rlllhe parts of the track will also be kept on perfect grade and in perfect alinement, and thus minimize-dangeroit derailments, accidents, etc-while the cost oit maintaining the tracks and rolling,` stock in repair will be materially reduced.v Also there will-be less jar and vibration incident to the movement of the rollin j stock, and theli'fe Voit the rails will be greatly prolonged because of' the presenceof a continuouslydry road bed, and grass, weeds and like` vegetable. mattery yfill be'prevented from growing Vbetween rails, and danger of theties catch,-

ing fire from cinders will-be entirely obviated, allof which will be appreciated by those versed in the art.` Zll'iesey and' other advantages are obtained by theuseofmy improved road bed which will, within a br-iet-y time after cobstruction,` reducey the general"-x cost oi construction and maintenance, owingy tothe perfect condition in which the bed and` tracks remain and the` reductionV ot"v re-` pairs to the minimum;

l claim:-A

l'.` ln a railway road` bed and trackcon' struction, the-'combination of a bed of; earthor the like, ties and track rails laid thereon, and a covering of water-proof material including cement as an ingredient over the surface of the bed between and beyond the ties and rails and over the major portionsl or the like, ties and track rails laid thereon, and a covering of a water-proof material including cement as an ingredient for the surface of the bed between and beyond the ties and rails and providing a substantially continuous covering for the bed and the ties, the vibratory movement of the ties being independent of the covering between the ties, said covering sloping outwardly and downwardly beyond the sides of the rails and being at the highest level on a longitudinal line centrally between the track rails and ties and thence sloping from the ties downwardly and inwardly and also downwardly and outwardly beyond the ends of the ties.

3. In a railway bed and track construction, the combination of a bed of earth or the like, ties sunk into the bed to points just below the top surfaces thereof, said bed having outwardly and downwardly sloping surfaces beyond the sides of the rails and between adjacent sides of the ties, and having sloping surfaces between the longitudinal center of the road bed and the lateral sides thereof from the center of the road bed outwardly.

4. In a railway bed and track construction, a bed of soft earth, ties embedded therein at their central portion and having their ends partially projecting above the surface, and a covering of which ce-v ment forms an ingredient, presenting a permanent hard surface and laid in sections above the ties and bed, the surface being inclined in two directions with reference to the ties, and said 'sectional covering permitting vibratory movement of the ties on the bed without fracturing the covering.

In testimony whereof I affix my signature.
