' To all whom may concern:

Be it known that I, SIGMUNDSPITZER, a

- subject of the Emperor of Austria, residing at Vienna, Empire of Austria-Hungary, have invented certain new and useful Improvements in Hulling-Machines; andI do hereby declare the following to b e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. A L -My invention relates to improvements in v, milling-machines for grain; and the object is to-construct a machine by which the grain is thoroughlydivested of the hulls, bran, the., inan expeditious and reliable manner; also, to vproduce a means by which to' correctly graduate or'regulate the distance between the hull- 'ingfstone and the roughened shell or casing.

' in elevationof my hulling-machine.

The invention consists in the construction 'and arrangement of parts, as will be more fully described hereinafter, and specifically pointed out in the claim, reference being had to the accompanying drawings and the letters of reference marked thereon. l The same letters indicate the same parts in the different figures of the drawings, in which Figure l represents a vertical section, partly Fig. 2 is across-section of the hullin'g-casing. Fig. 3 is a detail view, on an enlarged scale, ofthe roughened surface of the hulling-casing.

In the drawings, A represents the hullingstone, which is roughened on its surface by furrows or otherwise, vand is mounted on a vertical shaft, a, in the upper part of the machine.

The shaft has suitable journals, and its lower part rests in a suitable step, b. The stone A is surrounded by a casing or shell, C, of sheet- -p steel, and made in two parts, as seen in Fig. 2, so as to be adjustable. Two screws, c, are attached firmly to the two'parts of the casing, and pass through suitable threaded brackets, d, or nuts, and are operated by hand-wheels or cranks, so as to graduate the distance between the stone and the casing as desired. The grain vis admitted through the feed-spout e, and after being exposed to the action of the hulling-stone and roughened shell is carried through the spout f into the polishing-machine.

In this part is arranged av revolving. brush, B; which is secured to the same shaft as the stone.. The brush is nclosed in a casing of metal or clothing, or other suitable material.

wood, and consists of a cylinder with the heads g, and is covered with bristles, card The grain is thoroughly brushed or scoured, so as to relieve it of all dust or fine particles that have not been removed by the hullingstone and shell. The grain, in descending through the machine, is subjected to the action of an exhaust-fan arranged in thel upper part of the' spout D. This is connected by a spout, h, with the casing C,'and has a branch' spout, i,

for the hulls, chati", &c., while another spout, k, serves to convey the good kernels of grain f `to a suitable receptacle. The spouts may be provided with valves or ventilators, as desired. The casing Gis roughened on its interior surface by sharp points or'edges of similar construction to those of a wood-rasp, by which the hulls are better loosened or cutfrom the k'ernels, and, being lighter than the kernels of grain, can readily be withdrawn by the action 4 of the suction-fan and separated from the good grain.

The entire machine is arranged in a suitable frame-work,'F, and can be .thus easily transported from place to place.

The hulling-stone and brush receive their'. -motion through the pulley G, securedto the vertical shaft a. The upper and lower ends of the casing for the hulling-stone and the re- Volving brush must be made perfectly tight to prevent any dust from escaping.

The grain, having been exposed tothe action of the revolving brush B, passes through the outlet-spout Z to any suitable receptacle or place. A scale, m, on each side indicates the yamount of adjustment of casing C by means of ointers n.

lt will be readily understood by those skilled in the art that the hulls, chaff, Ste., will be most thoroughly removed by the hulling-machine herein described, while the grain will be r made perfectly clean and pure from the scouring action of the brush in its compartment; also, that no parts are liable-to get out of order, that the roughened shell of the hullingstone can be adjusted to a nicety, and that the IOO machine can be' produced at very reasonable cost.

' The rasp-teeth are struck up outof the'sheetsteel casing. .v
