    2 A.D. 1822.—N° 4692. Stanley s Improvements in Supplying Furnaces with Fuel, <$fc. NOW KNOW YE, that in compliance with the said proviso, I, the said John Stanley, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are particularly described and ascertained by the following description thereof, reference at the same time being had to the annexed- Drawings, in which said Drawings the same 5 letters or figures of reference are employed to denote the same thing (that is to say) :— The dotted lines a, b, b, c, c, d, represent a part of a boiler; a, b, the top; b, c, the end ; and c, d, the bottom of the said boiler; and as the bottoms of boilers are usually made convex upwards, c, d, represents the crown or highest 10 part of the bottom; e, /, g, j, is a hopper or reservoir for coals, made of plate or wrought iron; j, i, and /i, g, in Fig. 1, are two plates of iron, forming the bottom of the hopper; the lower edges of these two plates are not brought together, but allowed to be about three inches distant from each other, so as to form an opening or slit all along the bottom of the said hopper in the direction ] 5 of j, g, in Fig, 2, in order to allow the coals to fall through the said opening. A, in Fig. 2, represents an end view of the said boiler. &, Z, in Fig. 1, are two rollers placed immediately below the opening in the bottom of the hopper, so as that when the coals fall through the said opening they may fall upon or between the said rollers; those rollers I usually make six inches in diameter, and of a qq length corresponding to the width of the fire-place or grate to which the said machinery is intended to be applied, and I make tbe length of the opening or slit in the bottom of the hopper also to correspond with the length of the said rollers. The rollers 1c, l, (as represented in the Drawings Figs 1 and 2,) are fluted ; there are ten flutes in each roller, and each flute is one inch in depth; these ^5 fluted rollers are employed for crushing or breaking the coals, and for equalizing the quantity required for the supply of the fire in equal and successive periods of time; the absolute quantity of coals required to be supplied in any given space of time is regulated by the number of revolutions made by the said fluted rollers in such space of time, and by the distance at which the said rollers may be placed at from each other. Motion is given to the said rollers by means which I shall herein-after describe, and I regulate the distance between the said rollers by the ordinary and well-known method of applying adjusting screws and sliding brasses or bearings to the axle of one of the said rollers, as shewn at m, in Fig. 1. iv is one of two pinions by which one roller turns the other, as in common use. Immediately below the aforesaid two fluted rollers I place what I shall herein-after denominate a fan; it is composed of an iron axle or spindle w, n, in Fig. 2, lying horizontally and parallel with the aforesaid fluted rollers. Two or more sets of arms (as the lenght of the fan may require, two only are required for the length exhibited in the Drawing) 40 30 35
