S. VASOON AND A. GUIIII'D, OF CINCINNATI, OHIO.

GRINDING-MILL.

Speccaton of Letters Patent No. 20,310, dated May 18, 1858.

To aU whom may concern:

Be it known that we, SALvAnoR Vascosv and ADOLPHE Grimani), of the city of Cincinnati, Ohio, have invented a new and useful Improvement in Grinding-Mills; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon and made to form part of this specification.

Similar letters and figures refer to like p arts of the improvement.

The nature of our improvement consists in the combined arrangement of parts composing the mill, with which we make one notliable'to get out of order in its running gear and the grinding surface will not become dull with the same amount of wear as those in ordinary use, and can be made cheaper for grinding a given quantity of grain than any mill in common use and will not heat the grain in the process of grinding and occupy less space.

To enable others skilled in the art to make and use our improvement we will proceed to describe its construction and operation by referring directly to the accompanying drawings.

Figure 1, is a longitudinal sectional view of the mill showing the end of the stone. Fig. 2, is a transverse sectional view through the mill stone and other parts of the machinery, and Fig. 8 represents the gearing used for giving the proper motion to the grain crackers.

(c, a,) is the general frame work of the mill.

(B) is a French bur stone mounted on the shaft (.I,) and attached firmly to it by any suitable means so that the stone can be revolved by a belt working over the pulley 7L on the end of the shaft (O, O,) is a concave piece made of French bur stone and attached to the frame work (CZ, ch) which frame work will be made of metal and the whole will be adjustable up and down with the screw (g.) and cross pieces (f, f,) for regulating the edge of the stone (B) and the bottom of the concave (C, C,) apart.

The dotted lines (s. s, 8,) in Fig. 1, represent the place for the gearing for giving motion to the shaking shaft (13,) and breaking rollers (O', O,) But two of the gear wheels one on the stone shaft (J) and the other on the shaking shaft 13, are represented by 7c and (m) in Fig. 2.

.1() is the hopper in which the grain is placed to be ground. Y

(11,) is the bottom of the hopper and swings, by being attached with straps of leather and is acted upon with the cam (14,) on the shaft (13,) by striking the rod (12,) which rod is attached to and moves the bottom (11) and thus jars the grain from the hopper, down between the breaking rollers (C, C,) which rollers are furnished with grooves as represented-and as the grain passes between them it is broken and passes from them into the chute (O) and then passes between the edge of the stone (B.) and concave (O C) as represented and is ground to any requiredneness by adjusting the edge of the stone and concave apart with the screw (g.) v

(712,) is the chute in which the ground grain passes from the mill into the box The edge of the stone and inside of the concave will be furnished with grinding surfaces-and will be made for grinding grain of all kinds.

Cob and corn can be ground together by this mill, by adjusting the breaking rollers `apart to suit for breaking the cob which is effected by moving the pillow blocks 8, out in which one of the breaking rollers revolve and then adjust the mill to suit the size of the pieces of cob as it comes from the breaking rollers for grinding. When the cob is ground up with the corn it will be used as feed for stock.

The wheels 4, 5, 6, and 7, are employed for giving motion and the right direction of it to the breaking rollers ((l C).

A mill of this description furnished with one stone (1,) foot in diameter and 8, inches face with 500 revolutions per minute can grind from siX to eight bushels of grain in one hour. And a stone 1-1; feet in diameter 12 inches face with 400 revolutions per minute will grind from 9, to 12, bushels per hour. And a stone 2, feet in diameter and 16, inches face with 250, revolutions per minute will grind from 12 to 15 bushels per hour. The facts stated above I know from actual experience having had the mills in l justing the cylinder and concave apart as operation. before described for grlndlng.
