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.
“The patentee admits the fact of friction-wheels, or rollers, having been long used to the axles of carriages, and rests his claim upon particular mode of applying them. The carriage wheels consist of a rim and two sides, so as to form a hollow box; through openings in the centre of these sides, the axis is to pass. This axis is to be surrounded with friction-wheels, which lie within the box, their axes running in holes in the casings which form the sides. Small friction rollers, it is said, may surround the axes of these friction-wheels, &c. &c.
The objections to this plan, which immediately present themselves to us, are its complexity, and its being no better than others which are much more simple. For the rest, we have heretofore expressed our opinions on the application of friction rollers and have no inclination to go again over the same ground."
