. The Civil engineer and architect's journal, scientific and railway gazette. Architecture; Civil engineering; Science. My next improved machinery and apparatus is a wheel adapted to run upon the common road or upon the rails of a railway. Figure 8 is a side view, and figure 9 a cross section of the wheel, the wheel is formed as shown, as if the conical railway wheel were placed outside of the common wheel; if the wheel be formed of wood the felloes should be broad enough to take both tires, the outside tire may be the same as that used for a railway wheel, and tlie road tire the same as usual. I consider H inch sufficient ditfijrence in the radius of the two wheels; the best mode to fijj. the spokes will be as shown, alternately to cross them; the would be best of cast iron in the usual way. The only part of the wheel which I claim as my invention being the form of the rmg, any usual method may be used, and any material employed; the best mode to form the ring will be to make the wheel in the usual way and then shrink the railway tire b, b, upon it, then when this is turned in the lathe and the edge likewise, tlie road tire c, c', may be shrunk on afterwards in the usual way ; or the tire iron may l)e rolled to the entire shape, and the wheel put to- gether upon the usual railway system. D is the nave, t the axle, and y the spokes. TILGHMAN'S RAILWAY BAR. The nature of the improvement consists in so forming the bar that there shall be a reducticm of the height usually given to the f between its head and the base on which it rests ; thereby diminishing the leverage of the rail, while its strength and capability of being firmly secured to the cross-tie, are provided for by the addition of a rib directly under the centre of the base, which rib may be made plain, trapezoidal, or with a lower web. To fasten the rail, the lower rib is inserted in the cross-ties, and wedged securely to its place, wliere it is supported conjointly upon the ordinary base, and th
