Be it known that I, HERBERT J. KRATZER, a citizen of the United States of America, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Road-Beds for Railway-Rails, of which the following is a specication.

The primary object of this invention is to provide an improved road bed for the laying of railwayvrails which in itself will be practically permanent, in which provision is made whereby the rails c an be removed without destroyingv the road bed.

Another object is to provide an improved manner of securing ralls to this-improved road bed. v

A further object is to provide an improved road bed which in addition to being permanent, improved means are provided whereby, when the rails are mounted in position, the usual truing or leveling of the rails is done away with.

A still further object of this invention is to provide an improved construction of road bed in which the rails will be resiliently mounted in the road bed, therebyproviding a noiseless sup orting structure.

Other and flirther objects will appear in the specification and be specifically. pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a fragmentary plan View of a portion of this improved road bed,`showing the rail portions mounted thereon.

Fig. 2 is an enlarged transverse section of eferring to the drawings, 1 designates a road bed, preferably constructed of concrete, 1 or the same can be made of any self harden`v ing lastic material, said road bed being rem orced by the bars 2 and 3.

Formed in said road bed -are a pair of longitudinally arranged grooves 4, each of said grooves having expanded side walls 5 formed adjacent the bottom thereof, and outwardly Baring walls 6 formedadjacent the top thereof, the bottom 7 of each of said grooves 4 land said expanded side walls,4 5 being lmed by a metallic channel member 8.

In the\construction of` this improved road bed, it is g'eferable to first elevate the channel mem rs 8 to the desired level, said channel members being several feet. in length. Forms are then mounted on each of the channel members relative to the making 4 of the upper portion of each groove. The

body of concrete is then mounted under and around each of the channel members and around the forms, said body of concrete be- 4 ing reinforced in any desired manner.

When the forms, not shown, `are removed,

a pair of grooves as described is the result, f

the channel members 8 being leftA embedded in the body of concrete. The

l grooves 4 are then ready for the reception of the rails and their supporting structure, in which wooden blocks 9, 4which are the approximate length of the width of the channel members 8, are rst laid in an abutting relation in each vof said channel members, said blocks being first treated with a preservative, such as creosote oil. Tar oil is then poured on the blocks 9 to serve as a filling around and between the blocks and also as a further'- preventive- These blocks 9 are against deterioration. of a thickness so that the upper surfaces adjacent the ends thereof will engageagainst the inwardly extending flanges 10 =of the channel members 8. RailsA 11 are then mounted in each groove 4 on the laid blocks 9, said rails being gaged relative to yproper wheel tread, and the rail securing lag screws 12 are engaged into the blocks 9 thereby holding the rails in proper position. Abody of sand 13 is then laid over each base of each rail-l and on top of the blocks 9. Filling bricks such as 14 and 15 having inclined surfaces 17 and 18, respectively, are then mounted in place against the rails and on top of the body ofsand, the inclined faces of said bricks bearing against the outwardly surface 16, such as asphaltum is' then mountved on the concrete body between the inner rows of bricks 14, and wearing surfaces such ,as 19 are lled in against`the outside rows of brick.15. This completes theconstru'c-` will serve as deadenersto the sound on ac-Q count of the fact that 'the jarring of the f rolling' stock when applied to the rails will be transferred to the wooden blocks, and since said blocks are resilient, said blocks will serve somewhat as shock absorbers to 4 the jarring strains. v

Owing to the fact that it is found that o1l will commence `deterioration of concrete, attention is called to the channel members 8 which will containl the tar oil relative to the blocks 9, which will prevent the oil from coming in contact with the concrete road bed.

The body of sand 13 which is'illed in over the blocks 9 after the rails have been mounted thereon will serve as an insulation to said blocks 9 against water seeping into the channel members Sand around the blocks, thereby preventing dampness and subsequent deterioration to the blocks. The

30 bricks 141:v and 15 will also assist preventing water from getting to the blocks 9, although said bricks are primarily intended to serve as good wearing surfaces adjacent the rails,

and also to protect the upper edges of the walls of the grooves 4.

Attention is also called to the inwardly extendin bers 8 W ich will serve as a reinforcement to the concrete walls of the groove against 40 downward strains, and at the same time serving as a reinforcement against upward strains duringl the undulating movements of the rails relative to the resiliency of the blocks 9 while rolling stock is passing over It is known that the life of street railway rails is very short on account of the traflic thereover being heavy, and in the present day methods of removing worn out rails,

the whole roadbed is broken up. It is therefore the intent of this invention to provide a permanent road bed with pairs offrail seating grooves, in which the filling in or supporting elements or members relative to the rails can be easily removed without destroying any part of theroad bed, as all of theparts which are mounted in the grooves 4 of this improved road bed can easily be demounted and removed.`

Furthermore the manner in which the rails are .secured in the grooves provides means for the better securing of the rails to the road bed than heretofore, as the rails anges 10 of the channel mem- Leonesa are practically keyed or locked tothe road n bed on account of the engagement of the wooden blocks 9 under the extending vianges 10 of the channel members'S. v After'the removal of worn out rails from an improved road bed of this character, the grooves 4 are found to bein the original condition in which they were made, and all that is necessaryis a repetition of the mounting of the building or filling structure as afore related, and the rails will be found to have the desired elevation without any additional adjustment or leveling of the wooden blocks 9.

What claim is:

1. In roadbed construction, a longitudinally arranged groove formed in the roadbed being wider at the bottom than adjacent the top, a rail mounted in said groove, removable sectional rail supportingmembers mounted in saidvgroove each having a rail base ,recessformed therein, said recesses of said members being for the reception ofthe base of said rail.

2.
