site sides, laterally projecting cantalivers supporting rail holding beams. I

A further object is to. provide a construction of the character stated which isyespecially adapted for use with suspension trucks having wheels at both sides of the longitudinal girder and supporting the car suspended from the truck.

A further object is to provide a structure of the character stated which will be exceedingly strong and durable to withstand the strains and stresses to which it is necessarily subjected. 1

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating my Fig. 2 is a view in trans- Fig. 3 is an enlarged view in transverse section through the longitudinal section on the line 4-4 of Fig. 3.

1 represents my improved longitudinal girder which is supported on transverse the latter mounted on vuprights 3. The longitudinal girder 1 comprises parallel upper angles 4 constituting the upper chord of the beam and lower angle bars 5 constituting the lower chord of the beam. These angle bars 4 and 5 have gusset plates 6 secured between them, and the gusset plates of the upper and lower chords are connected by vertical and diagonal angle bar struts 7 and 8 respectively.

The longitudinal girder is connected to the transverse 'rders by shear plates 9 and suitable filler p ates 1'0 are located between the several angle bars and plates to permit the surfaces of the bars to come flush toand Fig. 4 is a view in horizontalgether and allow them to be securely riveted as shown. The. vertical angle bar struts 7 have triangular plates llsecured between them. These plates 11 are located at opposite sides of the girder and are strengthened at their inclinededge by angle bars 12 and at their lower horizontal edge by channel bars 13. At the outer end of the channel bars 13, angles 14 are secured and in turn are Se ured to {beams 15 supporting rails 16. The plates 11, angle bars 12, channel bars 13, and angles 14: constitute cantalivers, and a seen lear y n ig 3 and he cantalivers are located at directly opposite points on the sides of the longitudinal girder 1, and at the inner ends of the channel bars 13 bear against the vertical angle bar struts and insure a strong and rigid construction-to withstand the lateral strains at this point. j

17 represents a suspended car supported by trucks 18 having wheels 19 mounted to run on the rails 16, and it will be noted that the trucks are provided with two pairs of wheels at each side of the lon 'tudinal girder so that the car is supporte by the rails 16 at both sides of the girder, and the cantalivers operate to properly space the rail supports from the girder, and provide a stron and rigid mounting to sustain lateral or en wise thrust and to insure a rigid trackage for the car suspension. Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit andscope of the appended claims.

Having thus described my invention,

beams secured to the outer ends of the cantalivers. substantially as described.

2. In a suspension railway, the combination with a longitudinal girder, comprising upper and lower chords consisting of angle bars secured together with gusset plates between them, and struts connecting the gusset plates, of cantalivers secured to certain of the struts and projecting laterally from both sides of the girder, each cantaliver comprising a triangular plate secured to the vertical struts, channel bars secured to the lower edges of the plates at opposite sides thereof, angles secured to the outer ends of the channel bars, I-beams secured to the angles, and rails on the I-beams, substantially as described.

3. In a suspension railway, the combination with uprights, transverse girders connecting the uprights, and a longitudinal girder secured to and suspended from the transverse girders, of triangular plates secured to the longitudinal girder at opposite sides thereof, channel bars secured to the opposite sides of the plates and to the longitudinal girder, angle bars secured to the inclined edges of the plate, and rail supports at the outer ends of the channel stantially as described.

4:. In a suspension railway, the'comhination with uprights, transverse girders connecting the uprights, and a longitudinal girder secured to and suspended from the bars, subtransverse girders, of triangular plates secured to the longitudinal girder at opposite sides thereof, channel bars secured to the opposite sides of the plates and to the longitudinal girder, angle bars securedto the in- -clin ed edges of the plate, angles secured to JOSIAH H.
