Abstract: The first part of my invention relates to the circular frame resting upon the axles of the deriving and steering wheels or upon intermediate frame supporting the machinery used for forming the propelling power. The second part of my invention 'relates to the fore part of the afterbody of the carriage, which rests upon and is extended in cylindrical or circular form or framework around the aforesaid circular frame of the fore-body, which rests upon the axles of the driving-wheels or upon an intermediate frame. This arrangement affords a support for the forebody of the vehicle; it also allows the said forebody to turn independently, the object being to enable the carriage to be steered in any direction by the regulation of the speed given to either of the (hiving-wheels. The third part of my invention relates to the inner hub attached-to the driving-axles and its projecting arm, which, when "in motion, becomes connected with a projection from the driving-wheels, the object of which is to prevent the engine being caught ,on a center when the power is being applied to the aforesaid driving-wheels. Claim: The circular frame of the forebody B B resting upon the axles K K of the driving-wheels C C.

Manufactured by American Road Steamer Co. - Philadelphia PA

Abstract: The nature of my invention consists in the construction and arrangements of the various parts of a steam-vehicle in such a manner as to best permit the application of steam-power to the same for the various purposes that a movable power of this kind may be applied to, such as moving over common roads, haul- ring heavy loads, plowing and other agricultural work, acting as a fire-engine, and in various other places too numerous here to mention. The two driving-wheels of this vehicle are arranged each side of a vertical steam-boiler by means of axles, which are firmly attached to the sides of the same, permitting the wheels to revolve upon these axles. These axles are made hollow at the center, so as to permit the passage of water through them, for the double purpose of keeping them cooled from the heat of the boiler, and at the same, time furnishing a supply of water to the boiler. The third or guide wheel of the vehicle is a peculiar device, and is so arranged that its use will give guidance and direction to the movements of the whole machine. The water-tank, which is formed of iron, carries a supply of water for the boiler, and forms the body or frame of the vehicle. It is bolted firmly at one end to the lower and front side of the boiler, and at the other end it rests upon the guide or third wheel, thus connecting the three wheels and boiler, at the same time forming a bed or floor for the engines and gearing, with room also for the engineer. The boiler is so arranged that it may be heated with wood, coal, or coal-oil. Thus all is arranged so as to give the greatest power, compactness, lightness, economy, simplicity and efficiency needed in a machine of this kind. Claim: he combination of hollow axles with the boiler of steam-vehicles, for the purpose of conveying water to the boiler, and for keeping said axles cool.
