To all whom; it may concern:

State of Pennsylvania, have invented a new and useful Improvement; in Railw'ayflohstruction, of -which 1 the following: is e' full,

clear,.and exact description, reference being had toIthe accompanying drawings,-forn1ing part of this specification, 'in-which'- Figure-1 is apersp ective view of asection of track constructed in accordance with' n'y invention. .Fig. 2 is a vertical section transversely of one of the girders; Fig. 3. is a --si"mi-lar section taken through the tie-piece. Fig. 4 is a perspective view-of the; tie-piece. j Figshdand 6 are perspective viewsshowing different types of clips, and Fig, 7 is alongitudinal vertica'l section showing a slip-joint My invention relates to substructure of railways,- and isdesigned to provide a. continnous-girder construction which may be easil y and. cheaply made'and, installed and'which .will give an efiicient and durable structure. 1 In the drawings, 2 represents thegirders, having flat upper faces 4, upen'which the-rails 1 are; supported vThe sides ofl-the girders arepreferably slightly con vex and terminate in -bottom flanges 3, which extend outwardly and are preferably turned up slightly at their edges to increase the strength, 1 The girders are provided in their tops and sides-with, re? cesses ordepressions 5, which are also extended through the bottom flanges, as shown,

These depressed portions are of arsuitable width and depth to receive the flattened Joad uniformly to-thaxrdad-bed inall postends 18 'of'the channel side-piece 16,'havin'g the flenges ji'Z. The flatten'edvportions 18ers; presided withfs-truck-u'p; lugs .19, which en; gage slots 20, cut in the tops of the girders.

Therai-lsiare held in place by clips 8,h av

in'g'. hooked ends 9, these'clips being inserted through slots in thesides of the-girders and heldin place either by a cutlug 14,-,whic'h-i bent dowmjas s'ho'wnin. Figs- 1 vtoll, or by a 'key 12, d riveh'through a h'ole' in the end, i'a's shownin Fig ,6;-

The, endsoflsthe girders in each continuous row are pretera blyiconneeted,byslip-joints;

which allow expansion and give a continuous "ind mm support-to the rail and transniit the tions smile load. This is illnstratedin ig, i

7, wherein the end oithe'left-ha-nd girder is contracted'andslips within the end of .the'

girder at the right hand of the figure.

, Theadvantagesof'my invention result from ,the simplicity,c'heapness, end'ease of construction -inassembling the parts. .A continuousysn pportfor. the rails is afforded, the

I springing of thew-ail endsqs prevented, and

the ballast can be easilyand-cheaply applied. -Manyvariations maybe made in theform between their 'ends; substantially as 'described.
