ROAD-BED.

Specicaton of Letters Patent.

Patented July 25, 1911.

Applieauon led September 24, 1910. Serial No. 583,636.

' To all whom it may concern.'

Be it' known that I, SHERMAN MAHURIN,

a citizen of the United States, residing at Frankfort, in the county of Spink and State `of South Dakota, have invented new and useful Improvements in Road-Beds, of

which the following is a specification. This invention relates to railroad road beds and more particularly to metallic road beds.

The object of the invention is to provide` a continuous and rigid supporting surface for the rails and to provide means for conveniently and expeditiously attaching said rails.

.A further object of the invention is the provision of novel metallic ties and stringere for interconnecting the ties and supporting the rails together with novel attaching means for the stringers and rails.

Further objects of the invention will appear as the following specific description is read in connection. with the accompanying drawing which forms a partof this application, and in which:

.Figure 1 is a top plan view. Fig. 2 is a section on the line 2-2-0f Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 1. Fig. 4 is a detail perspective of one of the ties. Fig. 5 is a similar view of one of the stringers. Fig. 6 is a perspective View of one of the connecting devices. Fig. 7 is an enlarged detail top plan View. Fig. 8 is a.

sectional view of a modified form `of Stringer. Fig. 9 isa section on the line' 9 -9 of Fig. 7. Fig. 10 is a section on the line 10-10 ofy Eig. 7. l

Referringmore articularly to the drawings 1 represents t e road bed upon which are mounted aplurality of ties 2 each consisting of a flat piece of metal with its ends formed into vertical upstanding flanges 3 which are adapted to engage and hold one side of the stringers 4. The stringers com-I prise a flat piece of metal having its opposite side edges bent downwardly into retain- -ing flanges 5 which are adapted to enter the road bed and prevent lateral slipping of the tiesand stringers. The flanges are cut away as at 6 so as to permit the ends of the stringers to rest upon the ties 2- and the flanges 5 extend downwardly into the road bed between the ties. The stringers. are mounted upon the ties as shown in Fig. l with their ends slightly separated so as to permit expansion and contraction thereof and are held in position upon the ties by means of fastening devices or clips 7 'which are adapted to enter T-shaped slots 8 formed 1n the ties 2. These fastening devices are vsubstantially U-shaped in outline and have projecting from their vertical leg a bracing vents the head 10 from becoming disengaged with thestringers. In applying the clips the horizontal leg thereof isplaced in the T-shaped slot and moved forward until the head engages over the Stringer. The clip is then moved laterally in the slot so that the extension 9 will rest upon the portion of thetie on the side of the slot. Two of these clips are placed in each slot to engage the adjoining stringers and in order to prevent their accidental removal from the slot one of the clips is provided with a pivoted locking pawl 11 with ashouldered end 12 adapted to enter a slot 13 formed upon` the 'opposite clip as shown in Fig. 9. This construct-ion permits disengagement of either clip.

Throughout the length of each'stringer on opposite sides of its longitudinal center are formed L-shaped slots 14' in which the clips 7 are adapted to be placed and forced against the base flanges of the rails 15 as shown. Thel pivoted dog 11 in this instance will engage the wall of' thelongitudinal leg of the slot when the clip is positioned in the lateral leg thereof as shown in Fig'. 10. It will thus be seen that I have provided a boltless road extension 9 which rests upon the tie and prebed Whichmay be expeditiously*constructedn Y and which will be durable and'ellicient in operation.

In the modification shown inl Fig. 8 a Stringer 16 is shown having clips punched up adjacent its outer edge to receive theouter base flange of the rails. The Stringer is provided with the usual`L-shaped slots adj acenty its inner edge so as to receive clips adapted to engage the vinner base flange of the rail.

Having thus described the invention, what isclaimed is- 1. In a device of. the classr described, the combination with a plurality of metallic ties having end-flanges stringers mounted upon said ties and having one side edge abutting against said flange, said ties having slots therein, clips mounted in said slots and adapted to engage the opposite side edge of said stringers, and means carried by one of the clips and coacting with the opposite one to prevent disengagement of the clips. from theslots.

2. In a device of the class described,lthe

-the clipsin'the slots, heads ont-he clips to en'- combination With a plurality of metallic ties, gage the inside edges of said stringers, and of stringers mounted thereon and having the means carried by the stringers for securing ends thereof closely related, flanges on the the rails thereto.

slots in said ties, pairs of clips mounted in said T-shaped slots, a locking pawl pivoted SHERMAN MAHURIN' to one of the clips of each pair and adapted Witnesses: to engage the opposite clip of the pair to lock C. R. WILSON,
