| Transcript | THE BERLIN IRON BRIDGE COMPANY, SUSPENSION BRIDGES. ^^7HERE ARE many locations to which none of the bridges shown heretofore are adapted, and where the peculiarities of the location ® I ® demand a suspension bridge. The suspension bridge is especially adapted for long spans, where, either on account of insufficient foundation, or the danger of heavy ice carrying away the piers, it is found impracticable to put in any piers between the banks. There are also locations where a rock anchorage is easily found, and the expense of a suspension bridge is much less than an ordinary truss bridge. The suspension bridge differs from a parabolic truss- bridge in the fact that it is necessary to anchor the cables to a mass of masonry, while in a parabolic bridge the cable anchors itself against the upper chord of the truss; the pull of the cable or lower chord, and the push of the arch or upper chord being equal and in opposite' directions, one counter-balances the other. The cables of a suspension bridge are not of sufficient stability to carry heavy concentrated loads, and therefore it becomes necessary in order to stiffen the bridge, to put in what is known as a stiffening truss, which distributes a concentrated load over several points. Some of the largest bridges in the world are built on this plan, noticable of which is the beautiful structure connecting New York and Brooklyn, known as the " Brooklyn Bridge," and also the bridge at Niagara Falls, built many years ago by the elder Roebling. For long spans, and where the expense of piers is large, there is no bridge so economical and so well adapted as the suspension type. We are prepared to present plans and estimates for suspension bridges, having had a large experience in this class of work, and illustrate on the two following pages two of these structures, built by us within the two last years.
