Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
For an improvement in the Application of Power to Machinery; Robert Mitchell, Cynthiana, Harrison County, Kentucky, October 10.
"This patent is for one of those outrages upon the A, B, C of mechanics, which might astonish us were they not so frequently perpetrated. The screw of Archimedes is to be made to elevate iron balls of 200 lbs. each, which are to fall upon a bucket wheel, near its top, and be delivered at the bottom into a trough, down which they are to run into the " Elevator." "The power of one horse will run the elevator with twelve balls weighing 2400 lbs.; this weight applied on the side of a wheel 30, or any other convenient number of feet in diameter, may be applied to the running of any kind of machinery," says the patentee, and no doubt he is correct, provided his machinery does not require more than the power of half a horse to turn it.
If power is to be thus gained, why fatigue and feed the horse? A little of this swindled power may as well be applied to the turning of the elevator, and the circulating medium of iron be thus rendered perpetually current."
Description from the Journal of the Franklin Institute, V5 1830 pg. 23.
