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. Only the patent drawing is available. This patent is in the database for reference only.
“For the application of Steam to produce a Rotary Motion; Joseph Mount, Nashville, Tennessee, July 16.
It would be in vain to attempt an explanation of the very complex machine above named. The arrangement of the parts has been a business of much thought, and the constructing of the machine would be one of much expense. The patentee claims the whole arrangement of the various parts, and bringing all the parts which require to be packed, into convenient situations to be packed, or tightened, without removing any parts of the engine, thereby removing the greatest difficulty which has attended the working of all former rotary engines.
We have repeatedly noticed the objections to rotary engines, and certainly one of them is the difficulty of packing, but still, we do not think this the greatest difficulty. In most of the plans which have been proposed, a greater difficulty than packing, is, the obtaining in large machines the accuracy in form which they require, and the impossibility, in many parts, of making the packing a remedy for this defect, without producing an enormous portion of friction; these difficulties, we apprehend, are not removed.' The greatest, however, has been, that, hitherto, with the same quantity of fuel, less power has been obtained from the rotary, than from the reciprocating engine, whilst, at the same time, it is more expensive.”
