and Tunstall, Staffordshire —Inventor.

An illustrative model of a bar-trellis suspension bridge,to make a more secure and cheap roadway over rivers,without obstructing the navigation by high-masted vessels.The greatest part of the weight is laid on the lower partsof the suspension towers, by tapering the constructionthroughout from the base, beginning with strong suspend-ing bars, and decreasing their strength to the summit, sothat the tops of the towers shall have the least possibleweight upon them, trussing and bracing together the sus-pension bars. The shortest suspension bars being madethe heaviest, and the longest bars the lightest, withoutaffecting their efficiency, each being constructed so as tobe equal to its task, expense is saved by lessening thequantity of material to be used, and undulation andlateral motion as in chain bridges avoided, the bracingand trussing giving rigidity and a united hold.

42 Woods, F. F., 5 Pelham Terrace, Brompton —

Inventor, Patentee, and Manufacturer.

Patent union paving, for public and private roads; anew application of materials, being a combination of woodand stone; designed to possess the following advantages:—Less noise than stone-paved roads; less mud than roadsmade with loose stones; less slippery than wood paving;besides having a better foothold for horses, and beingmore durable than the latter.

The principle of this invention consists in the applica-tion of stone and wood to the construction of a pavingmaterial, which is effected in the following manner: thestone which is employed for the purpose, is broken intopieces, and inserted in grooved or perforated blocks ofwood, as in fig. 1, which is a section of one of the blocks,showing the position of the broken pieces of stone in thegrooves or holes of the block.

The grooves or holes in the wood are about 3 or 4inches deep; 2 or 2 ^ inches wide, and 2 inches apart.The pieces of stone are driven into the grooves tightwith a hammer, and their angles or corners are made topenetrate the wood at each side, so as firmly to retaintheir position. The pieces of stone are driven hard onto the wood at the bottom of the grooves or holes, whichare previously lined with a small portion of a compo-sition consisting of small gravel and ground lime. Whenthe grooves or holes are filled up with the pieces of stone,a portion of the same composition is poured over thesurface, and compressed with a brush or otherwise, inorder to fill up any interstices that may remain betweenthe stones and the wood. There are various designswhich may be formed for the arrangement of the grooves,either for beauty or utility; and circular holes may bealso used, according to a - variety of patterns. Theseought to be of 3 or 4 inches diameter, and within aninch or half an inch of each other. When straightgrooves are used, which are most easily constructed, the
