PETER SIEMERS, OF ST. LOUIS., MISSOURI.

HoMINY-MAGHINE.

Specification of Letters Patent No. 18,413, dated October 13, 1857.

To all whom t may concern:

Be it known that I, PETER SIEMERs, of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Hominy-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, in which- Figure l is a top view; Fig. 2 a section through A', and Fig. 3 a side elevation.

Similar letters on the different figures represent corresponding parts.

My improvement consists in fixing in the periphery of a cylindrical stone, a series of double corrugated knives, or breakers, and of combining the said stone (having the knives arranged as aforesaid,) with a cylinder, having burs on its inturned surface, the said burs to move in a ldirection opposite to that of the said knives, .or breakers, where by the corn will be broken by the action of the knives, and thrown against the burred cylinder, which, moving in an opposite direction, will hull it, and throw it back in contact with the stone, which will polish it, thus completing the operation of making hominy much quicker, and make it better than any other method with which I am acquainted. And I also combine with the aforesaid arrangement an automatic alarm, which shall give notice when the aforesaid operation is completed.

To enable others to make and use my improvement, I will proceed to describe its construction and operation, which is as follows:

A is the frame of the machine.

B is a cylindrical stone, fixed on an axle, which has its bearing in a pair of plummer blocks fixed on the frame as shown at c, and in the periphery of the said stone a series of double corrugated knives or breakers are fixed as shown at a, which are to be made as shown at Fig. 5, X being an end, and 'Y a side view of the same.

D is a hollow cylinder, the ends of which are to be made of wood or metal as the case may require, and the shell is to be made of sheet iron or other sheet metal, and is to be punched full of small angular holes from the outside toward the center, whereby burs will be formed on the middle surface, as shown at b b. The ends, of the said cylinder are also to be lined with sheet metal punched similar to the shell, as shown at '0,

Fig. 2. constructed is swung on the axle of the stone B and is made to revolve in a direction opposite to it, through the agency of the two cog wheels E F and the pulley Gr. The cog wheel E being fixed against the end of the cylinder as shown, and the wheel F on the shaft H, as is also the pulley G, so that if a belt is led from the shaft C, around the pulley G, it will cause the cylinder to revolve in a direction opposite to that of the stone, as shown by the direction of the arrow, Fig. 2.

The upper part of the cylinder I) is covered with a box, shown at II, which for the sake of perspicuity has been omitted in Figs. 1 and 3. This box may be made in any convenient shape, so long as it covers the cylinder and forms a proper receiver for the hopper J. This hopper is made of the ordinary form and has a canvas or leather leader fixed around its lower end, so that when it is desirous to charge the cylinder, this leader can be readily entered into the receiving nozzle c through a hole cut in the box I, directly opposite the receiving nozzle, in which the operator can put his hand and control the position of said leader.

In the bottom of the receiving nozzle a small slide is placed, which is closed after the cylinder is charged, so as to keep the grain from falling out. The arrangement is shown in dotted lines at c, Fig. 2.

In the end of the cylinder D at e a small pin is fixed, which in revolving strikes the pins 7 1^ fixed in the head of the screw s, which causes the said screw to turn a given distance, every revolution of the cylinder, whereby in a given time the follower H is detached from the screw which causes the bell t to strike an alarm.

Let it be desired to charge the machine and put it in operation. The cylinder is turned, so as to bring the receiving nozzle to correspond with the hopper. The machine is then supplied with the required amount of corn. After which the slide j is closed, the leader removed and the machine put in motion. The knives, or breakers, then commence to operate on the corn, so as to break it, take out the heart, and throw it against the burred cylinder,.which complet-es their duty. The cylinder, revolving in the opposite direction, catches the broken kernels, and hulls them and throws them back against the stone, which completes its duty The said cylinder having been so A,

and the stone in carrying the particles around on its surface polshes them, which completes its duty, and the entire operation, and by the time this operation is completed the follower H Will have run off of the screw s and the bell t struck the alarm or in other Words give notice that the Work is done.

The machine is then stopped. The slide n is removed, which allows the hominy to fall from the cylinder into anything placed to receive it.

It will beseen that the corrugated knives break the kernel and take out the heart, and that the burred cylinder hulls it, and the stone polishes it, each of these parts thus performingla separate function, and each of them necessary to carry out the design, which is to make pure hominy.

Now a cylinder having corrugated knives or breakers has been used before, in combination With a burred cylinder, as such an arrangement is shown in the application of William Davis. But this arrangement only breaks the kernel and hulls it; but does not polish it, which is the function performed by the stone in my machine. I am aware that mere substitution is not patentable, unless the thing substituted performs a separate function and is a real improvement,

which the stone in the relation I have placed it really is.

I therefore claim- The stone, in combination With the corri1- gated knives and burred cylinder, when used for the purpose specified, and operated
