Newest Recent Inventions Interesting From the Scientific and Mechanical Viewpoint
â€¢ EACH month, about five thousand patents are issued from the patent office at Washington, exclusive of trademarks, but including design patents.

On the other hand, many are novel in their utilization of known principles; and it is our endeavor to present here those of interest to any mechanically-inclined reader, whether or not they can be used by the public.
