39 F. 323 | U.S. Circuit Court for the District of Southern New York | 1889
The patent in suit granted to complainant, May 6, 1884, is in the words of the claim, for “a collar or sleeve button having a hollow head and stem; the said head, stem, and the base-plate or back of the said button being shaped and made of a single continuous piece of sheet-metal, substantially as shown and described.” The specification and drawings describe and illustrate a button in the form of a stud. It is made of a single piece of metal, without soldering or joints. By means of any suitable dies, a metal plate is pressed into the form of a cap, with a flange or rim at the bottom, and then the sides of the cap are pressed together about the middle in any suitable manner, to form the head and stem. The prior state of the art may be sufficiently understood by referring to only two of the several earlier patents in the record. The patent to Stokes, No. 171,882, granted January 4, 1876, describes a stud composed of one piece of sheet-metal, in which the head and stem are made by striking them up or raising them out of the metal base-plate by means of a punch and die. The stud is of substantially the same form as the stud of the complainant’s patent, except that the head is flat instead of round; the stem is hollow; and the head is solid. The patent to Keats, No. 177,858, granted May 9, 1876, describes a button or stud made of a single piece of sheet-metal having a hollow head and hollow stem, and is of the same form as the stud of the complainant’s patent. It has an entra shank or base-plate. In making it, the sheet-metal blank is formed in two sections, having the desired configuration, one of which is doubled over upon the other, and the edges are brought together by lateral pressure. It thus appears by the two prior patents referred to that the complainant was not the first to make a hollow stud, or a hollow stud from a single piece of metal, or a stud from a single continuous piece of metal, or a partly hollow stud from.a single continuous piece of metal. So far as appears, he was the first to make a stud from a single continuous piece of metal ‘in which the head was hollow and round in shape. The stud of the Stokes patent would be
