Opinion

BLATOHFORD, District Judge..

This suit is founded on letters patent granted to W. IJ. Dudley and Lawrence W. Clark, as assignees of W. U. Dudley, the inventor, July 27th, 1S69, for an “improved hand-mirror.” The specification, signed by the inventor, says: “My improvement relates to that description of hand-mirrors for toilet use and other purposes, in which the frame that holds the glass is elongated at one end, to form a handle, or it may be similarly shaped at both ends. The usual mode of constructing such mirrors is to mount the glass in a solid frame or thin block of wood, either naturally of ornamental character, or afterwards made so by veneering, cut or shaped so as to be of similar contour to the glass, and with a projecting end formed to constitute a handle. Apart from the expense of hand-mirrors so-constructed, where a very ornamental appearance is required, there is not only a general want of strength, especially at the neck or junction of the handle with the body, but a great liability to fracture of the glass by the twisting or warping of the wood of which the frame or holder is made. This latter defect is not merely at first, or peculiar to any greenness of the wood or newness of the article, when fracture of the glass from such causes frequently occurs, but is induced at any time by sudden and violent changes in the temperature of the atmosphere, exposure to damn and extreme heat. My improvement obviates such defect, being non-absorbent as regards damp, and free from any liability to warp, at the same time combining beauty with strength at a comparatively trifling cost; and the nature of my invention consists in rdounting the' glass on a base piece, of wood or other material, having a stiffening extension running into the handle, and embedding the whole in a composition or cement of suitable description, that, on hardening, forms the back, edges and outside handle of the mirror.” The manner of constructing the article is then described, with references to the, drawings: “A, is the glass; B, a base-piece, of wood or other suitable material, preferably of similar contour to the glass which is designed to be mounted on it, but elongated at one end, which extension, with a strip of metal or other stout material at its back, forms a handle-stiffener, C, to the mirror. This base-piece, with its handle extension or stiffener, C, is then laid in a mould or on a block, face downward, with or without the glass, A, in its place, and a composition or cement of any suitable plastic material, applied in sufficient quantity to cover the back and extend beyond the edges of the base-piece, B, and so as to surround the handle-stiffener or end extension of the latter, when an upper mould, of suitable configuration, and having its interior embellished with any ornamental device or devices, is pressed down upon the cement, which, when hard or dry, on removing the upper mould and lifting the article from the lower one, constitutes a smooth or finished, and, it may be, highly ornamental outer back and handle, D, impervious to damp, exempt from warping, with its consequent liability of fracturing the glass, and preservative of the wooden or other base-piece, which may be of a cheap and rough construction; and that, by its end extension, with strengthening strip at its back, gives not only a general stability to the whole article, but especially stiffens the handle at its junction with the back or body, where it is naturally weakest or most liable [919]*919to break. The under mould or block may also be embellished with any ornamental device. The glass may either be laid on a cushion of the lower mould, so as to be embedded at its edges, simultaneously with the forming of the outer back and handle, in the plastic composition or cement, or it may be afterwards inserted and restrained to its place' on the base-piece, either by an ornamental bead around the edges of the glass, and formed of the same composition or cement of which the outer handle and back are made, or of different material afterwards run around and applied thereto. As I do not desire to coniine myself to any particular composition or cement of which to form the outer handle and back, but design to use any plastic substance or compound of suitable character, it will here suffice to state, that a mixture in equal parts, more or less, of paint, sifted sawdust and shellac, forms a very desirable composition for the purpose, and one which readily admits of the color being varied to suit different tastes or demands.” The claim is in these words: “I claim, as a new article of manufacture, a hand or portable-toilet mirror, constructed, substantially as described, of a base-piece, B, with its handle-extension piece or stiffener, C, glass, A, and outer back and handle, D, made of any suitable composition or cement, substantially as specified.”

The hand-mirror of the defendant is made of a cement applied in a plastic state, and afterwards hardened, and embedded in the cement and concealed from view are two flat wires or strengtheners, made of metal, and running from the body of the mirror part through the neck and into the handle, and serving to stiffen and strengthen the article, particularly at the junction of the handle with the body.

The defendant insists that the claim of the patent must be construed as being for a hand-mirror made by means of a glass mounted on á piece of wood shaped for the glass, and a handle, the handle being strengthened by a strip of iron, and the whole covered with a cement; that the defendant’s mirror is a hand-mirror with a composition back, the composition being strengthened by the two wires; that the only office of the wires is to give strength to the back, and they are not, in any sense, the base-pieces or foundation on which the cement is pressed; that, in the defendant’s mirror, the composition is the base or foundation, while, in the patent, the wood is the base or foundation; that the defendant’s mirror has nothing corresponding to the base-piece, B, of the patent, the two wires corresponding only to the stiffener, C, of the patent; that the base-piece, B, is an essential part of the article claimed, and is claimed in the patent as such part; and that, therefore, the defendant’s mirror does not infringe the patent. But, the patent is not fairly susceptible of this limited construction. According.to the description, the glass is to be mounted’on a base-piece of any suitable material, which base-piece is, at its end. to be elongated or extended through the neck and into the handle, the extension being made sufficiently strong not only to give general stability, to the whole article, but especially to stiffen the handle at its junction with the body, and the whole being embedded in a suitable cement, applied in a plastic form, and which, when hardened, forms the bade, edges and outside handle of the mirror. The defendant’s wires act as a base-piece or support for the glass, and the wires extend through the neck and into the handle, and act at the neck and in the handle as stiffeners, and there is an outer back and handle of cement. There can be no doubt that the defendant’s mirror is, in its construction, substantially the same as the patented mirror.

Various defences are set up in attack on the validity of the patent. To understand them, it will be necessary to give a history of certain events. The application for the patent sued on was filed on the 6th of August, 1806, the oath to the specification having been made by W. U. Dudley, on the 1st of August, 1866. The specification presented was in the same language as that attached to the patent. The application was rejected on the 23d of August, 1S66, as being anticipated by a patent granted to Alanson C. Estabrook, June 19th, 1S66.
