Specification of Letterslatcnt. Patented Aug. 5, 1919.

Application led May 1, 1919. Serial` No. 293,932.

To all 'Lo/1,0m it may concern.'

Be it known that I, JoHN OWEN DAVIS, a citizen of the United States, and a resident of Cushing, in the county of Payne and State of Oklahoma, have invented certain new and useful Improvements in Railroadlili Ties, of which the following is a specilication.

My present invention relates generally to railr'oad ties, and more particularly to composite ties, my object being the provision of a tie formed of structural steel and concrete, so arranged as toprovide for the ready introduction of the plastic material in connection with the metal, without the necessity for forms, molds, and the like.

A further object is the provision of a metal and concrete tie, the parts of which are so arranged as to provide for the reception and ready securing of cushion blocks upon the rail seats.

Further objects, and the particular advantages of my present construction, will be apparent from the following description, reference bein made to the accompanying drawings forming a part of the specification, in which i Figure 1 is a perspective view of `my improved tie complete, i

Fig. 2 is a vertical longitudinal section taken through one end thereof on an en larged scale, and

Fig. 3 is a transverse vertical section taken through one end of the tie seen in Fig. 2.

Referring now to these figures, and particularly to Fig. 1, my invention proposes a tie including a metal shell, having sides l() and 11 which extend from one end to the other and form a rigid structure, the oppiosite ends of the shell being so Aformed as to provide downwardly opening hopper-like end portions generally indicated at 12 and 13, and of which the end portions of the sides 10 and 11 constitute parts. lt may be possible to form these hopperlike end portions ofthe tie by pressing sheet metal, or they may be made up by outer and inner upwardly and inwardly inclined plates 14e and 15 ateach end, both these outer and inner plates 14 and 15 being riveted or other wise connected, as -at 16, to the sides 10 and 1l.

ln the arrangement as shown, the upper inner edges of the inclined plates 14 and 15 thus coperate to define the rail seats at the oppusite ends ef tie, althcugh the aldea 10 and l11, as shown, are provided `with upper `upright flanges 17 which projectat` their ends above the upper edges of the inclined plates 14 and l5, so as to extend along opposite sides of cushion blocks 18, the latter of which are preferably formed of wood and seat upon the upper edges of plates 14 and `l5, as well as the upper surface of the plastic material` within the hopper-like end portions of the rail, as presently described.

`These" cushion blocks 18 thus serve to cushion the rails in use, as well as a means of receiving the usual spikes 19for holding the rails in place, and these cushion blocks 18 are preferably covered by upper horizontally disposed metal plates 20 having openings 21, as seen at the right of Fig. 1, and in spaced relation, through which the spikes I19 are driven. n a f Thus, with the metallic shell formed and the cushion blocks 18 disposed in place, the latter of which are secured by transverse bolts 22, projecting at their ends through the end portions of the upright flanges 17 of the sides 10 and 11, the tie may be conveniently reversed and the plastic material 23 poured into; the hopper-likeend portions thereof, and the operation, except for the drying of the plastic material, is linishedby merely scraping the surplus plastic material away by passing any form of straight edge along the lower edges of the plates 14 and 15 and the end portions of the sides 10 and 11.` y

The plastic material 23 is preferably reinforced by series of crimped spikes 24, extending transversely therein through the end portions of ;:the opposite sides 10 andll and as shown particularly in Fig. 3.

Itwill be noted that my invention thus provides a rail tie in connection with which all of the advantages of a wooden tie are presentgasthe spaced sides 10 and 11A between thehopper-like end portions where the rail seats are located, is, entirely open for the reception of the road ballast, so as to obviate the possibility of diiiiculty in the way of center binding.

It; is also obvious that my invention proposes a tie in `which the plastic filled portions of the metallic shell may be completed without the use of molds, forms, and the like, which in ordinary practice means: considerable expense in both labor and material. t

It is also to be observed in my particular construction of tie that the concrete is reine reread 'tram Witheet and entirely prntactnd from injury when the tie is placed in use,

vthe two spaced and'com'posite rail seats being rigidly connected by the side members which stand on edge so that kalldanger of splitting of the end portion ofthe tie isen- Ytirely prevented and all danger of splitting therails avoided, 1 v

1t will alsobe noted that the sides l0 and Y11 vare provided withopenings 10au for the maintain the rails in perfect alinement. It

is to be observed furthermore that the foregoing is true particularly in view of the inverted yhoppershaped bases of the rail seats which provide for a large bearing surface so that a smaller numberV of ties will be required per mile than the usual wooden ties. The tie proposed by my invention is in the f nature of a much. more permanent construc- ,tionV than usual, and obviously does away the hopper-like end with the necessity of frequentlytearin up tution' 4of wooden ties.

I claim p v Y '1.' A-rail tie consisting of a metallic shell (formed with downwardly opening hopperthe road-bed in thecase ofnecessary su stishaped end portions, and a plastic reinforcement within the said hopper-like end portions to cooperate with the shell in forming end seats at ythe' ends thereof.

2'. A rail tie consisting. of a metallic shell formed with downwardly Vopening hoppershaped end portions and having -spacedV apart sides rigidly connecting the said end portions, and plastic material. within the said hopper-like endlportions Aas and for the purpose described.

, Y' 3. A rail-tie'consisting of a metallic shell formed with downwardly opening hoppershaped end `portions and having sides, the ends of which form parts of the said end portions yof the tie, and which extend endwise inl a vertical plane between the end portions of the tie, and a plastic material within portions, as and. for the purpose described. Y Y

47. A rail'tie consisting of a lshell having j hopper-like end portions Vand side walls eX- tending `between and rigidly connected to said end portions, plastic material within andv filling the'hopper-like end portions, and reinforcing members extending into the said Y plastic material through the end portions of the said side walls.Y

A5.

6. A railtie consisting of a metallic shell having spaced parallel side walls and hopper-like end portions of which the end portions of the said side walls form the sides said hopper-like end portions having opposing inclined walls extending between and connected to the side walls and flush with one another at their upper edges, the saidside walls being provided with upper flanges projecting above the upper edges of the said inner and outer walls of the end portions of the tie, cushion blocks disposed between the said upright portions of the side walls above the hopper-like end portions, and connected to the said portions of the side walls, and plastic material filling the hopper-like end portions of the tie and coperating with the upper edges of the said inclined walls to form solid seats for the said cushion blocks.

Y'i'. A rail tie having longitudinally spaced hopper-like' end portions the sides of which are eXtended in unbroken relation between the said hopper-like end portions and in spaced parallel relation to one another, each of said hopper-like end portions having inner and outer inclined walls between the said side walls and having upper and lower edges terminating flush with one another, the said side Walls having upright portions projecting above the upper edges of the inner and outer walls, cushion blocks disposed upon the upper edges of the inner and outer walls, bolts extending through said cushion blocks and through the upwardly projecting portions of the side walls, and a plastic filling within each of the hopper-like end portions, coperating with the upperedges of the inner and outer walls to form solid seats for the said cushion blocks.
