Opinion

Green, J.

This is a suit in equity to restrain an alleged infringement by the defendants of letters patent No. 199,908, granted to the complainant as assignee of John W. Hyatt, for “improvement in the manufacture of sheets of celluloid and other plastic compositions.” Of the validity of this patent, there is no question. It has been critically examined by the circuit court of the United States for the district of Massachusetts, in the case of Celluloid Manuf’g Co. v. American Zylonite Co., 31 Fed. Rep. 904, and sustained in all respects. The only question involved in the present litigation is that of infringement. The patent in question concerns itself with the manufacture of sheets of celluloid and other plastic compositions. Celluloid, as an article of commerce, had been known for years. It is a compound of which pyroxy-line is the base or principal ingredient. Pyroxyline is made by subjecting vegetable fiber to the action of sulphuric and nitric acids. To the pyroxyline base is added a solvent, usually camphor and alcohol, which softens or dissolves it, and then pigment may be added to give color. Thef solvent •converts the pyroxyline into a jelly-like mass, which, upon being subjected to heat and pressure, and to a thorough mechanical kneading, resolves itself into a solid, homogeneous mass, which is called “celluloid.” It is rough and porous in texture, and somewhat brittle, when cooled. By the reapplication of heat, however, it is rendered plastic, in which condition it can readily Joe caused to assume any desired form or shape by moulding or pressure. In the manipulation and treatment of celluloid, however, one difficulty seemed almost insuperable. Experience had shown that for the manufacture of many articles, and for use in many respects, thin’ sheets of celluloid were far preferable to the more usual forms of bar or cylinder. Gutting or planing such thin sheets from a larger mass or block of celluloid had been accomplished, but not with such success as to justify the adoption of the processes. The great difficulty in the cutting or planing operation was that the plastic “material was apt to rise from the surface supporting it, and ride up the knife,” thus producing a material irregularity in the cutting, or stopping the operation altogether. Evidently, the great desideratum was some tool or [82] some process by which the slab or block of plastic material would be firmly and securely held in place upon the surface supporting it during the operation of shaving or planing it into thin sheets. It was to accomplish this purpose that the inventor, Mr. Hyatt, originated the process and the mechanism secured to the complainant by the letters patent in question. Hyatt describes his invention, generally, as an improvement in the manufacture of sheets of celluloid and other plastic compositions, and he declares that the objects of the invention are “accomplished by causing the union in a single slab of a number of sheets or pieces of celluloid, this being effected by pressure and heat, which contemporaneously amalgamate the sheets into a slab, and also force portions pf the under side thereof into channels or inclined grooves in the surface upon which the slab rests, which grooves are so arranged that, upon the hardening and shrinking of the material, the portions thereof in the grooves operate as a series of hooks or clutches to retain the slab in place, after which the plate supporting the slab is placed upon a machine for planing, whereby the material is shaved or planed off in sheets or pieces of any desired thickness, the sheets being subsequently dried in open frames, whereby they acquire and retain formation.” The specification in' the letters patent describes an apparatus for doing this, in which the middle of the upper surface of the plate is a slightly-raised boss, wholly covered with grooves and intermediate ridges or elevations, and the grooves on either side of the central vertical longitudinal plane of which, incline inward and downward towards that plane, and again, “the purpose of retaining the slab in position may be effected, also, by Vertical apertures in the plate, or, in fact, apertures or elevations of any order, in or upon or about which the plastic composition can be forced, and .then permitted to harden; the essence of this element of the invention being to affix a plate of plastic composition upon a plate immovably, by combined heat and pressure and subsequent cooling.” In other words, the improvement in the manufacture of celluloid sheets, invented by Hyatt, and as specifically described in his specification, consists in placing in a pile a number of rough sheets of celluloid upon a grooved plate in a chase or mould, subjecting them to a high degree of heat, and to great pressure, by which they are solidified into a compact slab, the lower portion of which is, at the same time, forced into the grooves, •then cooling the material, causing it tq shrink so that such part of the material as has been forced into the grooves, by reason of the shrinkage, Operates as a clutch Or hook grasping the metal of the tool with immense power, and holding the slab firmly by a tension towards the center against any. movement or force, either lateral or upward. “Thus,” to quote from, the • specification, “is the prime object of the invention accomplished,” ’ ■ ,

Of tlié various and numerous “claims” of the inventor, it is now contended'-that the’defendants are guilty of infringing the twenty-eighth, thirtieth y and .thirty-first. These claims are as follows:

“(28) The within-described process of making sheets of plastic composition, .wliich consists — First, in forming and causing the adhesion of a slab of the [83] composition to a plate; second, subjecting such slab to the operation of aplane to reduce it to sheets; and, third, drying the sheets thus produced in a frame, substantially as set forth.” “(30) A slab of plastic composition fixed upon a bed or plate, by the means substantially as herein specified, for the purpose of enabling the division or planing of the slab, substantially as set forth. (31) A plate carrying a slab of plastic composition affixed thereon by means of heat and pressure, substantially as set forth, and for the purpose specified.”
