Although I have described the tubular beam, and claim the right to use such in a bridge, it will be evident that other arrangements or constructions of beams may be used ; and therefore I do not confine myself strictly to the proportions of the various parts, as expressed in the drawings, nor to the material or materials, as above set forth; but intend to vary such as circumstances may require, while I maintain an analogous combination or combinations of them.

I do not therefore claim as my invention the combination of diagonal thrust braces and counter-braces, (which act by thrusts,) and vertical suspension rods; but that which I do claim as my improvement thereon consists in a combination of devices by which the diagonal braces operate either by thrust or tension, at pleasure, while the vertical rods at the same time operate either by tension or thrust; the said combination by which this peculiarity is derived being composed of the attachments of the diagonal braces and counter-braces, and upper and lower stringers, together with the double sets of nuts upon the vertical rods, one set being above and the other being below each stringer; the whole being substantially as herein before specified.

In testimony whereof, I have hereto set my signature this 8th day of June, A. D. 1846.
