BURR STONE FLOURING MILLS, 
EOR HORSE OR OTHER POWER. 
Plate VIII. 
There is no material so well adapted for flouring purposes as the French Burr Stone, 
and it is now generally used in this country. 
§ 82. Its first cost may he a little more, hut the greater durability and efficiency very soon 
over-balance any difference in first cost. 
Experience has shown that a Burr Stone should be as large in diameter as thirty or 
thirty-six inches to produce the greatest results, where the power to be used and the results 
are both considered, as larger and consequently heavier mills would require a greater pro- 
portion of a limited available force to propel them, and in fact would in many instances 
actually reduce the amount of work done. 
These mills have been made with especial reference to their completeness in themselves, 
and their adaptation to a demand which requires them to be simple and easily managed, and 
at the same time suited to grinding all kinds of grain and feed for man and beast. 
They are constructed so the running stone is hinged and balanced by a single point or 
cock head at the center, and yet the spindle runs upon two steel points at its extreme ends, 
in steps or sockets, which also form oil cups. (See plate viii.) 
These stones are brought to their bearing by means of an iron beam passing under the 
lower end of the spindle, and another over the upper end, and connected together by a 
screw rod outside the frame, and which is regulated by a hand wheel upon it where it is 
convenient to the person in attendance. 
The weight of the running stone is from four to six hundred pounds, and requires from 
three to four hundred revolutions per minute, at which speed and with less power they will 
accomplish as much work as is done with the four and five foot stones, and a greater propor- 
tionate amount with a more limited power. 
§ 83. Weight of mills complete, are six to twelve hundred pounds, cubic measurement ; 
when packed for shipment, about fifty to seventy-five feet.

Corn and Cob Crushes, also Bark Mills, for horse or other power of various and most ap- 
proved kinds furnished to order, at manufacturers' prices. 
§ 85. N. B. — All persons ordering Mills, should be careful to state which way they desire to 
have them run, whether with or against the sun, as they are made to run both ways. 
CORN SHELLERS, 
FOR HAND POWER. 
There is a great variety of Corn Shellers, including the various 
modifications of the old Pennock and Clinton Sheller, the most 
popular throughout the States for hand use. 
§ 86. They are made some with one and others with two Hop- 
pers ; some are adapted for large and others for small ears of corn. 
A good shelle r, with single hopper, will shell corn as fast as the 
ears can be fed into it by hand, and is easily turned by one man, 
often shelling a bushel of ears per minute. The double Hopper 
Machine will do nearly twice as much, and turns but little harder. 
Some of the hand shellers have separate delivery for the corn 
and cobs, while others do not ; those, however, which separate, 
generally run heavier on account of the power consumed by 
retaining and carrying the cobs around between the shelling 
plates to the delivery after the corn is shelled, and are a little 
more likely to get out of order ; they also require more care in 
j,^^,. ■ feeding and cannot shell as much per day. 
§ 87. "Weight from eighty to one hundred and fifty pounds. Cubic measure six to eight feet.
