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 is one of those disguised perpetual motions, which serve to deceive none but the merest tyro in mechanical knowledge, and which yet deceive numbers. One man is successively to raise a number of weights, all of which, in descending, are to operate upon a barrel common to the whole of them. Suppose there are ten weights of 50 lbs. each, nine of these are to be acting, whilst the tenth is being raised, and they are all, of course, to act with their whole power. The specification states, that the labour of a single man, can suffice to keep an immense weight in constant action:" we, however, are very apprehensive, that it would require a man with a large family, in order that he might station one stout fellow at each weight.
Most of our readers will excuse us from publishing the particular structure of this machine, whilst those who wish to know all about it, may do so by applying at the patent office.“
