Improvements in pedestal stands and the like

The innovation here is a method of scrollsawing using a bevel cut of about 5 degrees (the appropriate bevel depending on the blade kerf and the material thickness); closed shapes cut with a bevel can be either pushed below the surface or raised above the surface depending on the direction of the bevel; by rounding the edges, a carved effect results. This technique had been developed by an Italian priest, Monsignor Antonini. Antonini wrote to Hobbies Ltd.—a manufacturer of fret-sawing machines and blades, and a publisher of fretsawing patterns—to tell them of his innovation. Hobbies engineer Herbert Jewson paid Antonini a visit and the result was a licensing agreement for the idea. They patented the idea and the company called it the "Antofret" system after Antonini. The company then published plans for ninepence, which came with a license to sell exactly one item from the plan, each plan coming with a small paper "license" that was to be affixed to the item as proof that a separate plan had been purchased for it. |
