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 is a wheel, upon the contrivance of which much thought has been spent, as its construction fully manifests. Its intention is to preserve a vertical position in the buckets of a paddle wheel. Many patents have been procured for this object, and we have before taken occasion to express an unfavourable opinion of the whole of them; not merely on account of their complexity, but because we believe that if the end could be attained without a multiplication of moving parts, it would offer but little, if any, advantage beyond the ordinary paddle wheel.
The present plan is certainly not less complex than some of its predecessors. To move ten buckets there are not many less than 200 moving parts, and this certainly would present some objection both in point of cost, and in liability to derangement.
In several of the plans alluded to, one general principle prevails. The buckets, or floats, have on each end two pivots, inserted into the rims of eccentric wheels, the rims being of equal size, and having their centres one as far below the other as the distance between the two pivots on one end of a bucket. An arrangement of this kind will keep all the buckets vertical throughout their whole revolution. Although the plan before us differs considerably from this, yet a little analysis brings it back to an analogous, if not the same principle.
How far this scheme will obviate back water, we cannot now discuss, but will make a single remark on the subject. Suppose the paddle wheel iminersed to the centre of the shaft, the last dipping and rising buckets would then have no horizontal motion whatever, but would offer the same resistance as would a flat board of the same size, fixed to the side of the boat with its surface exposed to the water."
