MACHINE FOR BREAKING SHELLED CORN.

SPECIFICATION forming part of Letters Patent No. 442,086, dated December 2, 1890. A )plication filed March 31, 1883. Serial No. 90.119- (llo mode- To all who/it 66 may concern.-

Be itv known that I, ALBERT BALL, of Claremont, inthe county of Sullivan and State of New Hampshire, have invented a new and Improved Machine for Breaking Shelled Corn; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in corn-crackers or machines for breaking shelled corn.

The object in view is to so construct such machines that the parts which are subjected to the most wear may be removed and new parts substituted without unnecessary waste of material. To this end I construct the inner portion or cone in two parts, the lower one of said parts being armed with breakingteeth and capable of being readily removed without disturbing the upper part, and in conjunction with this lower armed part I use an armed ring or section of a cone which is i11- terposed between this armed part and the shell at that point, and in this construction lies the novelty of my invention, all as hereinafter described and claimed.

For the better understanding of the invention reference will be made to the accompanying drawings, which form part of this specification, and in which Figure 1 is a central vertical section of a corn oracker embodying my invention; Fig. 2, a plan view showing the inner set of breaking-edges; Fig. 3, a similar view of a ring secured to shell of machine. Fig. 4 is a view in detail of the fastening employed in securing together the two cone-sections, and Fig. 5 is a similar view of another fastening for said parts.

Like letters refer to corresponding parts throughout the several views.

In the drawings, A represents a shaft around which the cracker is placed and with which certain parts thereof revolve. This shaft is placed vertically and motion is imparted to it in any desirable manner.

The outer casing or shell of the machine (marked Bin drawings) is form ed of any suitable material and is composed of two parts,

each provided with a suitable flange a, and the two held together by means of bolts or screws I), passed through said flanges a. The upper portion of shell B is so constructed as toform a flaring hopper into which the corn is poured. The lower portion of said shell forms a receptacle for the corn after it has been reduced, and is provided with a suitable discharge-pipe C. Situated within the shell B, as shown, and secured to said shell by means of bolts or screws 0, is a ring or section of a cone D. (Shown in detail in Fig. This ring D is armed on its inner surface with teeth or breaking-edges d, and remains stationary in the operation of the machine.

It will be readily understood that when the ring D, or the teeth with which said ring is provided, become worn said ring may be removed and a new ring substituted therefor,

it thus being necessary to remove only such parts as are actually useless, while if these breaking-teeth were situated 011 the shell itself it would render the entire shell useless whenever said teeth became worn.

Keyed to the shaft A by means of a bolt or screw e and revolving with said shaft is a cone composed of two parts E and E, the two being held together by a rabbet-joint, as illustrated in Fig. 4-, or by a to11gue-andgroove joint, Fig. 5, or by any of the means well known to a skilled mechanic. The part E of this cone, as shown in Fig. 2, is provided on its outer surface with suitable teeth or breaking-edgesf, which, in conjunction with teeth (Z of ring I), serve to reduce the corn as desired. This part E occupies a position on the shaft or spindle that brings it directly opposite the ring 1), there being a suitable space g left between the teeth with which each of said parts is provided. Inasmuch as the part E'gOr that part of the cone which is provided with the breaking-teeth, is the only part of said cone that is subjected to any wear, a great saving of material is made when new parts are to be substituted for those which have become useless.

The operation and manner of using my device are as follows: Motion is imparted to shaft A, and in its revolution said shaft carries around the cone described. The corn to be operated upon is then placed in the upper or hopper-shaped portion of shell B, the part E of the cone acting as a guide to direct it to the space or opening 9 between the breakingteeth with which ring D and part E of the cone are provided. By the revolution of the teeth on part E, together with the teeth on ring or cone section D, the corn is reduced and passes down into the chamber or receptacle formed by the lower part of shellB, and thence off through the discharge-pipe C. When the breaking-teeth on parts D and E or on either one of them become worn, and

therefore useless, the bolts (1, which hold to gether the two parts of shell B, are removed and the Worn part-s taken out, new ones being substituted therefor, and the two parts of shell B again united.

The advantage of my invention is pally in the great saving of material plished.

Having thus described my invention, what I claim as new therein,and that for which I desire to secure Letters Patent, is-

p-rin ciaccom- The combination of the outer casing or shell 13, made in two flanged parts bolted together, the upper of which being flared or hopper-shaped, for the purposes set fortluthe cylindrical axle A, mounted in an axle-box made integral with the discharge-chute C, the grinding-cone-rigidly secured to said axle and composed of a smooth upper portion E and a serrated or toothed lower portion E, secured thereto, and the internally serrated or toothed-
