Opinion

Blatchford, C. J.

This is a motion for preliminary injunction on two patents. One is a re-issue granted to tho plaintiff October 22, 1878, No. 8,460, for an “improvement in waxing paper;” the original patent, No. 193,867, having been granted to him August 7, 1877. The specification of the re-issue says:

“ Tiie object of this invention is to apply paraffine or other wax to paper, to render the same water-proof. This paper is adapted to confectionery, to prevent the adhesion of articles, one to another, or to the paper, and the paper may also he used in wrapping butter, cheese, cutlery, and other articles requiring a water-proof protection. My improvement relates to a means for heating the wax, applying it to the paper, spreading or diffusing the wax into the paper, removing surplus wax, and then polishing the surface prior to winding the paper upon a reel. In the drawing, figure 1 is a plan view, and figure 2 is a longitudinal section of the apparatus employed by me. The cylinders, a, b, e, are hollow. * * * Each cylinder is supplied with steam to heat the same to tiie desired temperature, as in a calendering machine. * * * There is a trough, ii, beneath the cylinder, a, into which paraffine or other wax is introduced, and the proximity of the rollers, a, b, to this trough insures the melting of such wax, and the surface of the cylinder, a, takes up a layer of wax and applies it to the web of paper, s, that is drawn off the reel t and wound upon the reel w. The scraper, x, is applied to tiie cylinder, a, between the wax trough and the place of contact with the paper, to remove surplus wax, and only allow a uniform layer of wax to adhere to the heated cylinder, a. The paper passes beneath the heated cylinder, b, with the plain surface of the paper next to the heated cylinder. This serves to heat the paper, and molt and diffuse the wax throughout the fabric of the paper, so as to render it thoroughly water-proof. Tho paper now is drawn over the stationary scraper, l, to remove any surplus paraffine, and then it is brought over the heated cylinder, c, with the waxed surface in contact therewith. By this cylinder, c, the paraffine is again fused and spread into and upon the surface of the paper, thereby ironing and [586]*586smoothing the wax, and giving to the same a polished and uniform appearance, and the surface of the heated cylinder, e, by preference, travels in the opposite direction to the paper with which it comes into contact. The paper prepared in this manner is saturated and rendered transparent, or nearly so, by the action of the wax, and it is a new article of manufacture adapted to various uses in the arts as aforesaid.”

The claims are as follows:

“(1) In a machine for applying wax to the surface of paper, a heated cylinder revolved within the trough containing the wax, and acting to heat the wax and apply a layer to a web of paper, substantially as set forth. (2) The method herein specified of applying wax to the surface of paper, consisting in transferring the melted wax from a trough to the paper by a roller, moving the paper in contact with such roller, and removing the surplus wax by a scraper, substantially as set forth. (3) In a machine for applying wax to the surface of paper, the heated cylinders, a, and 5, in combination with the trough, n, and scraper, l, and means for supplying paper, whereby the heated wax is applied to one surface of the web of paper by the roller, a, and afterwards the paper is heated at the other surface, to draw the wax into the paper, substantially as set forth. (4) The heated cylinders, a, 5, e, in combination with the. trough, n, the scraper, l, and mechanism for revolving the cylinder, c, in the opposite direction to the movement of the paper with which it is in contact, substantially as set forth. (5; The method herein set forth of waxing paper, consisting in spreading the wax upon the surface, heating the paper from the opposite side, to spread and fuse the wax into the fabric of the paper, removing the surplus wax, and remelting and polishing the wax upon the paper, substantially as setforth.”

There is no dispute as to the manner of the construction of the defendant’s machine, in so far as. it is alleged to infringe the said re-issue. A lettered drawing of it is furnished, with reference to which the description of it, as given by the plaintiff’s expert, is as follows:

' A indicates a reel containing a web of paper, P, to be coated with wax or paraffine. B1, B, are guides, being small wooden rollers, over and under which the paper passes on its way to the machine. <7 is a steam-heated cylinder, about 10 inches in diameter, revolving in a trough containing melted wax or paraffine. At one side of said cylinder, extending the whole length thereof, is a wooden bar, A?, padded with felt, and forei- ' bly held against the cylinder, G, with a constant pressure, and serving to prevent more than a given quantity of wax or paraffine from being carried up to the paper. Close by, say about six inches therefrom, is a horizontal plate, F, somewhat wider than the paper and about 18 inches long, heated by a number of steam-pipes, g, beneath it. This plate, F, has a groove, A, A1, in its upper surface, all around its margin, about one and one-half or two inches from the edge thereof. One end, /, of the plate is [587]*587sel lower Ilian the other, and in the groove, h, at that end, are a number of lióles (see dotted lines) which allow wax taken oil the under side of the paper, passing over the plate, to pass through. Upon this heated plate, F, and receiving heat therefrom, are two diffusers, J. These are bars of wood covered with thick felt and with cloth over all. They arc 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 diffusers 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 permitting the brush to rock or incline. The diffusers, J, are weighted, and they and the brush, K, rest on the paper, and occupy about one-half of llie surface of the plato, 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, W, one and one-fourth inches in diameter, reaching entirety across the machine from side to side, the upper surface of which is flat and dressed smootli for half an inch in width. The operation of the machine, as given by the plaintiff’s expert, is as follows: The steam is first turned on, and the entire apparatus is properly heated, before commencing to run the paper thro ugh. The web of paper on the reel, A, passes first over the guide, B1, 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, G, from which the surplus wax has been removed by the bar, 7?, serving as a scraper. The cylinder, G, which acts to heat the wax in the trough, 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.
