J. " This is a motion for a preliminary injunction founded on letters patent granted to Eugene A. Heath, October 10, 1871, for an "improvement in cuspi- dors." The specification says : �" Be it linown that I, Eugene A. Heath, of New York city, in the state of New York, have invented certain new and useful improvements in cus- pidors, of which the following is a specification setting forth what I consider the best means of carrying it into efEect. The accompanying drawing forma a part of this specification. Figure 1 is a vertical sec- tion, showing the construction in its proper position ; and figure 2 a double view, the strong Unes being a section in an upset or overturned position and the dotted lines an elevation in its upright position. Similar letters indicate like parts in both the figures. I form separately three metallic parts and unite them, after suitable preparation, tightly and strongly by soldering. The lowermost, A, is of cast iron, thick at the extreme bottom and thinner towards the top. Its upper edge is rabbeted and nicely flnished to receive the lower edge of the sheet metal part, B, and form a flush exterior surface therewith, as shown. B is a piece of sheet iron pressed in a Grrimshaw press, or otherwise formed in the proper dome shape, and of exactly the proper diameter, and with a vertical flange at its upper edge, as shown. C is a conical piece which may be sirailarly formed into shape. Its lower edge has a flange which matches closely inside the flanged upper edge of B, and its upper edge is turned over by the ordinary tinsmith's tools, or otherwise, and made to embrace a wire ring, D, to stiflEen it; the construction of which is obvions. On soldering the several joints smoothly, and prop- erly decorating the surfaces, there results a metallic cuspidor, not liable to fracture, and lighter than ordinary cuspidors on its upper side, and much heavier than ordinary cuspidors on its lower side. One of the important ends attained by my invention is extraordinary stability. If the cuspidor is upset by any chance, and caused to lie for a time in the position indicated by the strong lines in figure 2, the excess of weight in its ��� �
