NEW RESULT FBOM OLD PROCESS. — A patent for an electrical insulator and method of making same describes a porcelain insulator for use with high-tension conductors, made, according to the process shown, in two or more separate parts or shells molded so as to nest or fit into each other, and which when dried are coated with glaze, placed together with the open side up, and extra liquid glaze poured into annular channels between the parts. When placed in the oven for firing in this position, the extra glazing material melts, and flows down as the clay shrinks, and fills the spaces and any crevice or crack which may form in the process or firing. It was held, that while neither the making of insulators in parts fitted into each other, nor the uniting of such parts by glazing, was novel, the combination of them with the further step of supplying an extra amount of liquid glaze sufficient not only to fuse the parts into a whole, but to fill all crevices, the result being a superior article, constituted invention, and was not anticipated by anything in the prior art. While the application of an old process to a similar or analogous subject, with no change in the manner of the application, and no result substantially distinct in its nature, will not sustain a patent, even it the new form of result has not before been contemplated, yet, if a new combination and arrangement of known elements produce a new and beneficial result never attained before, it is evidence of invention as a general rule.
