SOME SUCCESSFUL PATENTS.

Once a patent takes on, it begins.,to pay, and the patentee's income is then insured. A man obtained a patent in the United States for a slight improvement in chaff-cutters, and after eight months sold it for £8000. Another inventor obtained a patent to thresh and clean grain, and sold it in fifteen months for £12,000; while a third had a patent monopoly in a special printer's ink, and finally sold it for £12,000. These are ordinary cases of minor inventions involving no great inventive powers, and of which hundreds go out of the patent office every year. New Zealand inventions can likewise be placed in the same successful list, and amor- his clients Henry Hughes lias many such, who are, he is happy to. say, doing well. If you have invented anything that fills a want, or replaces any less efficient contrivance, obtain expert information and patent it. For this purpose the office of Henry Hughes (A. R. Holdship, manager), 183 Hereford street, Christchurch, is fully equipped for advising the inventor on the spot.
