BRIDGE.

Specification of Letters Patent.

.ratented May 15, 1906.

Application filed February 13 1906. Serial No. 300,851.

To (ti/Z whmn it may concern.-

Be it known that I, CHARLES KUTZ, a citi- Zen of the United States, residing at Louisville, in the county of Stark and State of Ohio, have invented new and useful Improvements in Bridges, of which the following is a specification.

This invention relates to bridges, and has for its object to provide a truss-bridge embodying strength and simplicity of construction.

In the accompanying drawings, Figure 1 is an elevation of one of the bridge-spans. Fig. 2 is a plan view. Fig. 3 is a vertical section on the line 3 3 of Fig. 1. Figs. 4 and 5 are cross-sections on the lines 4 4 and 5 5, respectively, of Fig. 1. Fig. 6 is a sectional detail of one of the end-post shoes. Fig. 7 is a plan view of the shoe, and Fig. 8 is an elevation of a modification.

Referring specifically to the drawings, 10 denotes the top chord. This consists of a plate 11, to which are riveted on opposite sides angle-irons 12. The horizontally-extending flanges or legs of the angle-irons are at the .top and extend outwardly from the plate and flush with the top edge thereof. The diagonal end posts 13 each consist of a plate 14 and angle-irons 15 on each side thereof, which are riveted together in the same manner as the top chord. The plate 11 of the top chord extends beyond the ends of its angle-irons into or between the angle-irons 15 of the end posts, and the plates 14 of the end posts fit at their upper ends against the Extending over the joint thus formed between the plates 11 and 14 are gussets 16, which are riveted to said plates on opposite sides thereof. Corner-caps 17 are also provided for the top chords and the end posts, said corner-caps being riveted to the angle-irons of these parts. The feet of the end posts rest in shoes 18, consisting of cast-iron blocks, which. are recessed on top, as at 19, to receive said feet. The bottom chord comprises bars 20, which are secured to opposite sides of the shoes by bolts 21, which extend across the outer ends of said shoes in grooves 22 therein.

At the middle of the span is a post 23,

which extends between the topchord and a cross-beam 24. Said post and beam are ordinary Ibeams. The post is cut away at the top to fit the top chord and rests at its lower end on the cross-beam. It is fastened to the top chord by a strap 25 and to the cross beam by angle-irons 26. The cross-beam also supports thebottom chord, the lower edges of the bars 20 resting on the horizontal flanges or legs on the angle-irons 26. The bars are also riveted to the upright flanges of the angle-irons.

The diagonal brace-rods 27 extend under the cross-beam 24 and through the cornercaps 17, the projecting ends of the rods being threaded to receive fastening-nuts 28. Two brace-rods are employed for each panel. To the bottom of the cross-beam 24 is secured, by clips 29 or other. suitable means, a block 30, which is grooved on the bottom, as at 31, to receive the brace-rods. At the bottom of the bridge are brace-rods 32, which are arranged in pairs on opposite sides of the crossbeam 24. The brace-rods are secured to and extend diagonally between the cross-beam 24 and the lower chord 20.

For short spans the structure shown in Fig. 1 will be employed. The structure shown in Fig. 8 is intended for long spans. In this form two intermediate posts 23 and cross-beams 24 and two sets of diagonal brace rods 27 are employed. The bracerods extend from the top of the corner-posts, under the cross-beams, and through the cor her-caps, as before, and they are also provided with turnbuckles 33.

A bridge constructed as herein described can be readily and cheaply put up and unites great strength with simplicity of construction.

I claim 1. A truss-bridge, the top chord and end posts of which are beams built up of flat plates and angle-beams secured to the sides thereof, the plate of the top chord projecting at its ends beyond the end of itsangle-beams between the angle-beams of the end posts.

2. A truss-bridge, the end posts of which are built up of angle-beams with a plate therebetween, in combination with a top chord having a plate which extends between I beam, and a strap passing over the top of the 10 the angle-beams of the end posts and rests beam and down the sides of the post.

upon the upper ends of the plates thereof, In testimony whereof I have signed my and gussets covering the joint between the name to this specification in the presence of 1 plates. two subscribing witnesses.

3. A truss-bridge, the top chord of which CHARLES KUTZ. is a T-beam, in combination with an inter- Witnesses: mediate post which has at the top a vertical H. E. COX,

recess to receive the web of the aforesaid HENRY BENDER.
