 HAMUEBSCHLAO V. SCAMONI. 687 �set lower than the other, and iii the groove, U, at that end, are a ntimber of holes (see dotted liaes) which allow wax taken ofl the iinder side of the paper, passing over the platp, td pass through. Upon this heated' plate, F, and receiving heat therefrom, are two difEusers, J, /. These are bars of wood covered with thick felt, and with cloth over all. They are long enough to reach entirely across the web of paper, and are about four and a half inches wide and two inches thick. Immediately beyond these diflusers is a brush, K, having at each end a trunnion playing in a slot in a standard, there being one standard on each side, and the trunnions per- mitting the brush to rock or incline. The difEusers, J, are weighted, and they and the brush, K, rest on the paper, and occupy about one-half of the surface of the plate, and serve to hold the paper in close contact 'with the plate. Beyond the further edge of the plate, but not far from it, is a steam-pipe, M, one and one-fourth inches in diameter, reaching entirely across the machine from side to side, the upper surface of which is flat and dressed smooth for half an inch in width. The operation of the machine, as given by the plaintiff's expert, is as follows: The steam is flrst turned on, and the entire apparatus is properly heated, bef ore commencing to run the paper through. The web of paper on the reel, A, passes flrst over the guide, B i, and then under the guide, B, and thence, in a slightly upward direction, to, over, and in close contact with the surface of the upper side of the steam- heated revolving cylinder, C, from wWch the surplus waxhasbeen removed by the bar, E, serving as a scraper. The cylinder, G, which actg to heat thewas in the trougb, also takes up wax and applies it to the under side of the web of paper. The paper then passes to and over the heated iron plate, F, with the under or waxed surface in contact with said plate. The wax now begins to corne through the tissue of the paper to the upper side thereof, which upper side is next brought in contact with the heated diSusers, J, J, which, by means of the pressing of their heated surfaces on that side of the paper on which the wax is not applied, thoroughly Incorporate the wax into the substance of tho paper. As the paper passes on under the brush, K, that device operates to finish the spreading and equalization of the wax. The paper emerging from under the diffusera, /, J, and the brush, K, and still in close contact with the heated plate, F, is drawn across the marginal groove, h, in the plate, which groove acts as a scraper, and removes any extra wax still remaining and which can be spared, and the paper then passes over so much of the heated plate as is outside of tKe groove. Pinally the paper passes over and in contact with the top surface of the heated pipe, M. �It is contended that the defendaat's machine infringes claima 1, 2, 3, and 5 of said re-issue. The infringement of claim 6 will be first oonsidered. The theory of the defend- ant is that the melted paraffine, being very fluid under heat and having great penetrating power, when brought in con- tact with the thin, raw, or itnsized paper is absorbed almost instantly into its pores by capillary attraction; that the ��� �
