In re Midgley
Opinion of the Court
delivered the opinion of the court:
The appellant filed his application for a patent on a process and apparatus for incorporating cords in rubber sheets. It is stipulated that claim numbered 1, rejected by the various tribunals in the Patent Office, is the only one in issue here. This claim is as follows:
1. The method of building a composite sheet of rubber and parallel cords which consists in feeding the cords in parallel relation under equalized tension, applying them while in this condition to a sheet of rubber traveling at the same speed as the feed of the cords, locating all the cords on the rubber at the meeting point of the cords and rubber by rolling pressure in the predetermined .positions they are to occupy with relation to one another, holding them in such position until they adhere to the rubber, and then applying additional rolling pressure on the entire surface of the cord and rubber sheet to cause the cords to sink further into the sheet.
This claim sufficiently sets forth the essential elements of appellant’s invention without further description. The First Assistant Commissioner justifies his rejection of this claim by reference to a United States patent to Marquette, No. 1321223, issued November 11, 1919.
Furthermore, it is quite obvious, from an examination of the Marquette specifications, that a flat-surfaced cord fabric was well known to the art at the time of their filing, and is therein fully disclosed. To quote:
Various methods have heretofore been devised for the proper covering of the cords, and for the production of cord fabric. But certain of these processes were slow, while other and more rapid ones entailed the subjecting of the cords to pressure, distortion, strain, and breaking of the fibers. Of this latter- class were those processes which included the passing of the cords and the rubber stock between calendar rolls, while causing sufficient pressure between the rolls to work the stock down between the cords, and stick it to the cords. The difficulty was that the high pressure, applied over the whole width of the sheet, not only acted- on the rubber but, unfortunately, acted also to flatten, distort, and disrupt the cords, and cords so abused, resulted in a fabric, whose cords were of inferior quality and wearing properties. Yet this calendar method had the very real advantages of rapid and continuous production of sheets of indefinite length, performance by simple and easily procured machines, and simple technique.
We conclude that the decision of the commissioner is right and it will be affirmed.
