For a machine for Thrashing all kind of Grain, called the " Paragon Thrashing Machine;" William C. Ross, Penfield, Monroe county, New York, April 1.

The novelty and merit of this machine depend upon the “ placing the apron on an inclination, and reducing the motion of the main, or thrashing cylinder, and consequently reducing friction, &c." The main cylinder is of wood, covered with iron, or furnished with six beaters, also covered with iron, to protect them against wearing. " The improvements relied on in this machine, are, in adding to the diameter of the main cylinder, consequently producing the same effect with half the revolutions, thereby reducing the friction, which the inventor considers the most discriminating feature of its utility; in the inclination of the apron; and in the conciseness of the machine and its appendages. I therefore claim all the above improvements, together with the privilege of varying the dimensions and proportions of the improved thrashing machine, as my fancy may from time to time hereafter dictate, so that all the while I adhere strictly to my principle, and depart not from it." Which principle is the making the cylinder twice as large as one of half the diameter and inclining the apron by which the machinery is fed.
