GRAIN-HULLER.

SPECIFICATION forming part of Letters Patent No. 313,984, dated March 17, 1885.

Application tiled Julyv9, 1884. (No model.)

To all whom it' may concern:

Be it known that I, FREDRICH BURG/K- HARDT, of St. Charles, in the county of St. Charles and State of Missouri, have invented a certain new and useful Improvement in Grain-Hullers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side elevation of my huiler. Fig. 2 is a vertical section of the hulling portion of the same, one part of the cone being in side view. Fig. 3 is a top View of one-half ofthe cone and shell. Fig. 4 is avertical section of theJl shell. Fig. 5 is an elevation of one ofthe plates of the shell. Fig. Gis atransversc section taken on the line 6 6, Fig. 2.

This invention relates to an apparatus more particularly intended for use in hulling corn in the manufacture of hominy, grits', die. It relates more particularly to an improvement on that form ot' huller shown in my application No. 148,915, filed November 16, 1884.

My improvement consists in features of novelty hereinafter fully described, and pointed out in the claims.

A represents a conical form of huller provided with a shell whose inner portion has rows of tufts B, the lower part having double the number of rows of tufts that the upper part has, for the purpose of increasing the hulling-surface- The huller-casing is preferably made in two parts provided with perforated lugs C, and secured together by bolts D.

The huller is supported by posts II or other suitable means. The tufts B,tl1at act to break and hullthe corn,are made of metallic brushes, as represented in Figs. 2, 4, and 6, and are arranged preferably in spiral form and held in place by the material from which they are made, are bent and passed through the perforated plates I of the inner portion, and are held from coming out by wires J, and from passing in by the outer portion, L, of the shell. One section or plate is shown in Fig. 5.

N are upper and lower rings to which the plates I are secured by screws 0,(sce Fig. 2,) and the plates may be further connected to the outer portion by screws I). (See Fig. 6) These plates or sections are preferably pro` vided with ribs T, as shown in Figs. 5 and 6, back of each upwardlyextending row of perforations. The ribs form backings to the brushes, supporting and making them more rivid.

tII represents the cone or runner located within the shell and supported on ashaft, U', provided with a driving-pulley, U2, and an adjusting-lever, U3, and screw Uf. The hulling-surface of this cone may also consist of metallic brushes made and arranged the same as ou the inner portion of the shell, or the same as shown in my application referred to herein.

The apparatus is preferably provided with a feed-hopper, V, or instead of the hopper the material could be discharged into the machine directly from a spout or chute.

The casing and shell may both be secured to the rings N.

I claim as myinvention- 1. In a huller, the combination, with a cone or runner having a hulling-surl`ace, of a shell having rows of tufts increasing in number toward the bottom, and consisting of metallic brushes, substantially as and for the purpose set forth. A

2. In a huller, the combination, with a shell having a hulling-surface, of a cone 0r runner having rows of tufts increasing in number to- Ward the bottom, and consisting of metallic brushes, substantially as and for the purpose set forth.

3. A perforated huller-plate, I, having metallic brushes forming rows of tufts, and the ribs T, formed on said plate to provide backings or supports for the rows of tufts, as set forth. 1

4. The combination of a cone having spiral rows of metallic tufts, and a shell having spiral rows of metallic tufts, said rows of tufts increasing in number' toward the bottom of both the cone and shell, as set forth.

5. The combination of a cone having ahulling-surface, and the shell, the latter consisting of inner and outer portions, upper and lower rings, and spiral rows of tufts forming the hulling-surtce, the inner portion being formed of sectional ribbed plates, and the rows of tufts increasing in number toward the bottom, as set forth.
