ends of two corrugated segments of cones, and combining with them corrugated, enclosing 

 casings supplied with two feeding apertures, and arranged in such a manner that corn and 

 cobs can be fed into one opening, and ground-shelled corn be fed into the other aperture, and 

 both be converted into meal. 



Shearman's Method of Feeding Grain to Millstones. An Improvement recently patented by 

 Simeon Shearman, of Goshen, Indiana, consists in an arrangement placed between the ordinary 

 hopper and the grinding stones, whereby the grain, in passing from the one 4o the other, is 

 winnowed and dusted by means of a fan-blast and appropriate arrangements. The blast 

 also acts upon the spindle, keeping both it and the grain cool and clean. 



Leavitt's Portable Grain Mill. 



THE accompanying figures represent an improved portable grain mill recently invented and 

 patented by Charles Leavitt, of the city of Quincy, Illinois, and for which the first premium 

 for grain mills was awarded at the State Agricultural Fair of Ohio, 1855. 



The nature of the invention consists in applying to a portable corn mill (in which the ex- 

 ternal portion or concave revolves upon a fixed cone) the following improvements : First, the 

 combination of the bed-plate, legs or supports, the breaker, and the main pivot, cast in one 

 piece. Secondly, in combination with the foregoing, a lever in two parts, attached to an 

 external revolving concave, constructed and arranged substantially as hereinafter described.

Fig. 1 is a vertical section of the mill ; fig. 2 is an elevation ; fig. 3 is a plan view of the mova- 

 ble rings; and fig. 4 is a plan view of the annular conductor. Similar letters refer to like 

 parts. 



The bed-plate a, legs or supports 6, ogee-breaker c, and vertical main pivot or journal d, 

 are cast in one piece. Upon a flange projecting from the lower edge of the bed-plate a is 

 placed an annular grooved conductor e, which has an outlet at /. Between the top of the 

 breaker c, and the base of the pivot, is an annular groove i, with an outlet at the bottom 

 thereof, for the purpose of collecting and discharging the oil from the pivot d, and preventing 

 it from mixing with the meal. A sleeve g fits upon the pivot d and revolves thereon, its lower 

 edge resting upon the bottom of the groove i. A top plate or cover h, having a circular open- 

 ing in its centre a little less than the base of the breaker c, is joined to the sleeve g by four 

 strong arms I. The plate h extends to the outer edge of the conductor e, and carries on its 

 under side square projecting scrapers n, which fit in the conductor and revolve therein. 

 The arms I are toothed on their under sides to correspond with the teeth in the breaker c.
