WILLIAM M. REED, OF CHICAGO, ILLINOIS.v

ELEVATED RAILWAY.

Specification of Letters Patent.

Patented March 20., 1906.

Application filed December 4,1905.v Serial No. 290,190.

To all whom it may concern: v

Be it known that I, WILLIAM M. REED, a citizen of the United States, residing at Chicago,.in the'county of Cook and State of Illinois, have invented certain new and useful Improvements inElevated Railways, of which the following is a specification.

, This invention relates to new and useful4 improvements in elevated railways, vand has for its objects, first, to dispense with the use of the usual cross-ties and to provide a longitudinal base for the track-rail; second, to

. provide an elevated railway construction in which, eXce ting the supporting means, the longitudina gir'ders and the track-rails form substantially the complete structure; third,

to provide a construction that shall offer' less obstruction to light and air and obviate much of the noise incident to the resentconstruction, and, fourth, to provi e a simple,

. p durable, and comparatively inexpensive construction.

With the above and other objects in view` this invention consists of the novel form and the combination and arrangement of 4parts hereinafter more specifically described, illustrated in the drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings,

. forming a part of this specification, wherein .like numeralsA of reference lindicate corresponding parts throughout the severalviews,

and in whiclr- Figurel is a perspective view. Fig. 2 is across-section on line 2 2 of Fig. lV Fig. 3 is an enlarged detail end view o the track-rail and girder. y Referring to the drawings by reference-numerals, 4 denotesy the usual post or column by which the different sections of the structure are supported.

5 5 represent cross-beams post'.

I provide an I-beam 6 6 or other girder or from4 .post :to

base having a horizontal upper flange 7 7 and a track-rail 8 fastened tot e same. Preferably the girders 6 6 are of metal and may be the ordinary I-beam or a suitable built-up girder or Stringer. The track-rails 8 8 are of thek usual. form and may be secured to the lon itudinal girders by any suitable means,`

suc as bolts 9 passing through the rail-foot l() and the head or top flange 7 of the girder 6, washers or bosses l 1 1 l on the rail foot and with the head and nut of the bolts.

The girders 6 6 are fastened at their ends to the cross-beams 5 5, preferably by angleplat-es or gussets 12 12. When girders -6 6 are used for an ordinary two-railed track, they may be made more firm against lateral deflection by braces of any desired character, such as 13, placed at suitable intervals. 14 shows the common braces fastened to post 4 andl supporting cross-beam5.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isf l. In an elevated railway, the combination of a supporting structure comprising columns, cross-beams and longitudinal metal girders of uniform height with and supported by said cross-beams, and track-rails seated directly on said longitudinal girders, substantially as shown and described.

2. In an elevated-railway, the combination of a supporting structure comprising columns, cross beams, longitudinal metal gird-4 ers of uniform height with the tops 'of said cross-beams, means adapted to give lateral 'stiffness to said girdersand track-rails seatu WILLIAM M. REED. Witnesses: l i
