As the apparatus is drawn along, these cylinders revolve upon their axles, which are mounted in the frame bbb. There is a small guide roller, or wheel in front of tlie frame to which the shafts are at- tached, and by wliicl) the appara- tus may be turned round, or guided in a curved course; rfrf is a thin plate of iron placed ob- liquely across the machine, in front of the rollers ; it is attached to the framing by rods and screws, and is thereby made adjustable to any height, so as to scrape the surface of the road evenly. Tlie foremost end of the scraper is curved, for the purpose of preventing the escape of the mud, which, being collected as tlie machine advances, runs along the inclined surface of the scraper, and is conducted to the side of the road. Thus the mud is proposed to be scraped off the surface as the apparatus advances , and the materials of the road compressed and hardened by the traversing of the rollers. It may be added, that in order to increase the pressure of the rollers, a box, to be affixed to the framework, is proposed to be placed over the rollers, which may carry stones, or other heavy materials, that might be ased in making or rooairing of the road.
