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.
"This engine and water wheel are to act precisely upon the principle of Barker's mill; in one case, steam, in the other, water, are to be the actuating agents. When steam is used, a hollow axis is to proceed from a boiler; upon this axis, a wheel is to be fitted like the wheel upon the axis of a carriage. The rim of this wheel is to be made heavy, so as to form a flywheel; the parts which resemble spokes, are curved hollow tubes, open at both ends. They are usually bent, so as to reach the rim on the side opposite to that from which they issue from the hub; an opening, or openings, made in the hollow axis, admits steam into each of the curved tubes; and this, by the force with which it rushes out, is to give a direct rotary motion. The wheels of carriages are to be similarly constructed; as also are the proposed water wheels.
The patentee calculates that such an engine will not only be simple in its parts but operate with great force. A boiler, of the high-pressure kind, is preferred. We are very apprehensive that with one really of the low pressure kind, his wheels would stand still.
In principle, this machine is precisely the same as some of the whirling globes, or wheels, exhibited in different histories of the steam engine, and which mark the infancy of this herculean instrument. Our calculations are egregiously faulty, or the patentee is altogether wrong in his anticipations."
