The engine had a truck in front, with four 30-inchwheels. The cylinders were inside the frames and were con-nected to a crank-axle of the form shown in Fig. 13. Theeccentrics were outside of the frame, and the eccentric rodsextended back to rocking shafts which were located under thefoot-board. The was of the bonnet kind, and hada deflecting cone in its center. The edges of the cone werecurled over so as to deflect the sparks downward, and thusprevent their passing through the wire bonnet, as well as pre-venting the bonnets from wearing out too Fig. 12. The driving-wheels of the engine were made of cast-iron,with hollow spokes and rims, which at the time was a re-markable novelty. The section of the spokes was of an ovalform, and the rim of very much the same shape as that whichis in common use at the present time. This kind of driving-wheel has since come into almost universal use in this country. .Another important Improvement adopted by Mr. Rogersin the construction of this engine, was the counterbalancingthe weight of the crank, connecting rods and piston. Forthis he filed a specification in the Patent Office, dated July 12th,1837. It is described as follows in the specification : The nature of my improvement consists in providing the section of thewheel opposite to the crank with sufficient weight to counterbalance thecrank and connecting rods, making the resistance of the engine less instarting and in running; also preventing the irregularity of motion causedby that siile of the whe
