Purpose: The patent covers a machine for sowing powdery (pulverulent) manure. According to the inventor, it protects "a new mode of arranging certain essential parts of the machine," asserted to be a valuable improvement upon a patent granted to him July 9, 1861 (identified in the source as US32800A).

Plain-language scope: A box (A) holds the manure and rides on two wheels (B). The axles drive into the ends of a roller (C) that forms the box bottom. A spring-loaded pressure-bar (D, springs a, adjustment screws b) seals the gap at the rear of the roller to stop manure escaping. Inside the front of the box, a horizontal gauge bar (E) with set-screws (F) is raised or lowered to set the discharge opening between the roller and gauge, controlling application rate. A clearer bar (G), mounted on springs (H) with set-screws, presses against the roller to keep it clean. Pawls (I) on the wheels engage ratchets (J) on the axle ends so the wheels turn the roller as the machine is drawn; springs (K) are adjustable to hold the pawls engaged (roller turning) or to release them so the machine can be drawn without turning the roller. Thills (L) attach to the box top, and a driver's seat (M) is carried on supports (N) tied to thill cross-pieces. The inventor contemplates two rollers in line, with inner bearings in a central transverse partition, each compartment having its own gauge, pressure-bar, and clearer — said to ease turning and even out manure distribution.

Claim: "The arrangement of box A, roller C, spring pressure-bar D a, gauge E, and spring-clearer G H, as and for the purpose specified."
